<p>The jQuery that current ships as part of WordPress is (as of WP 5.4.1) an older version of jQuery. As in ancient. This plugin allows you to instead use a much more modern version of jQuery, with optional compatibility for scripts that need the older jQuery calls.</p>
<p>This plugin also optionally allows you to securely select a public CDN for jQuery, including the appropriate Subresource Integrity (SRI) and CrossOrigin attributes. Using a CDN can speed up the loading of your website as there is a good chance a client visiting your website already has the identical file in their browser cache and does not need to fetch it again.</p>
<p>When a CDN is used, a small amount of code is added to your pages to provide a fallback where jQuery and the jQuery Migrate plugin are served from your site if either the CDN can not be reached by the client or if the SRI check fails.</p>
<p>The updated jQuery will not replace the core jQuery for administration pages. This is to avoid potential breakage of administrative pages.</p>
<p>The options for this plugin are managed from the WordPress ‘Dashboard’ in the ‘Settings’ area, using the ‘jQuery Options’ menu option within the ‘Settings’ area.</p>
<h3>Plugin Options</h3>
<p>There are four configurable options you can customize.</p>
<h4>‘Use Migrate Plugin’ option</h4>
<p>Enabled by default.</p>
<p>You may disable compatibility with scripts that require older versions of jQuery. This is not recommended.</p>
<p>The jQuery Migrate plugin provides compatibility with jQuery 1.9 through 3.0. It is enabled by default and provides compatibility with the version of jQuery that currently (WP 5.4.1) ships in WordPress, which is jQuery version 1.12.4.</p>
<p>Scripts written to use the version of jQuery that ships with WordPress may be registered with a dependency of <code>jquery-core</code> but use functions that are no longer supported in jQuery 3.5.1. When ‘Use Migrate Plugin’ is enabled, scripts that are registered with a dependency of <code>jquery-core</code> will trigger enqueuing of the Migrate plugin so that those scripts written for the older jQuery will still work. When ‘Use Migrate Plugin’ is disabled, then enqueuing of the Migrate plugin will only happen if scripts explicitly specify <code>jquery-migrate</code> or <code>jquery</code> as a dependency.</p>
<p>If some jQuery scripts break even with ‘Use Migrate Plugin’ enabled, they are likely written for jQuery prior to version 1.9. The only option in that case is to not use this plugin until you have upgraded that very old code.</p>
<p>It is highly recommended you update such old code as soon as possible, whether or not you plan to use this plugin.</p>
<h4>Note</h4>
<p>Please note that WordPress has provided jQuery for years, this results in many plugins and themes using jQuery out of convenience when they really did not need to.</p>
<p>Rumor is that a future release of WordPress may only use native JavaScript for everything JavaScript in WP Core. If hiring a JavaScript developer to update old jQuery code, make sure the JavaScript developer is wise enough to know when porting the code to native JavaScript makes more sense than continuing to use jQuery and when using jQuery really is the best approach. In other words, do not hire someone like me, I pretty much only use jQuery but that is admittedly not always the best approach, just the convenient approach.</p>
<h4>‘Use Content Distribution Network’ option</h4>
<p>Disabled by default.</p>
<p>By default, the updated jQuery scripts are served from within this WordPress plugin. This is because responsible plugin and theme developers do not (in my opinion) utilize third party resources by default.</p>
<p>I recommend you enable this option however doing so will result in front-end pages being served that reference a Third Party Resource. Links to those services and their privacy policies follows the section on Plugin Options.</p>
<h4>‘Use Subresource Integrity’ option</h4>
<p>Enabled by default.</p>
<p>This option only has meaning when the ‘Use Content Distribution Network’ option is enabled.</p>
<p>This option will add a Subresource Integrity hash that browsers can use to verify the resource retrieved is valid opposed to a modified possible trojan.</p>
<p>The only logical reason I can think of to disable this option is if you already have a different plugin that manages Subresource Integrity.</p>
<h4>‘Select Public CDN Service’ option</h4>
<p>Set to ‘jQuery.com CDN’ by default.</p>
<p>This option only has meaning when the ‘Use Content Distribution Network’ option is enabled.</p>
<p>This option lets you select which public CDN you wish to use from a list of five Public CDN services that are listed at https://jquery.com/download/#using-jquery-with-a-cdn</p>
<p>For many websites, the default ‘jQuery.com CDN’ is <em>probably</em> the best choice but it may not be the best choice for all websites, depending upon where the majority of your users are located geographically and which public CDN has a better response time in that geographical region.</p>
<h3>External Third Party Services</h3>
<p>When you enable the CDN option (recommended but disabled by default) a third party service will be used. You should make sure your website Privacy Policy makes users are aware of this. In the current version of WordPress (WP 5.4.1), the default Privacy Policy does make users aware that third party resources may be used, but you have to actually publish that policy and you should check it yourself in case it has been modified or in case the policy you have predates the current default policy and does not include a Third Party Resource notice.</p>
<p>This plugin <em>always</em> sets the <code>crossorigin="anonymous"</code> attribute in association with the Third Party Service. This attribute instructs the browser not to send cookies or any other authentication information to the third party when retrieving the resource. Most modern browsers respect this attribute but some may not.</p>
<p>By default, the plugin will set the <code>integrity="[[expected base64 encoded hash]]"</code> attribute in association with the Third Party Service. This instruct the browser not to use the downloaded resource if the hash does not match, protecting your users from possible trojans.</p>
<p>For SRI, this plugin uses the hashes associated with the files as provided by https://jquery.com/download/ with one exception (see the Hard-coded SRI Hashes section of this readme).</p>
<p>These are the potential third party services:</p>
<h4>jQuery.com CDN</h4>
<p>The default CDN used by this plugin when a CDN is enabled.</p>
<p>Link to service: https://code.jquery.com/</p>
<p>jQuery.com CDN is actually powered by StackPath.</p>
<p>Link to service: https://www.stackpath.com/<br />
Privacy Policy: https://www.stackpath.com/legal/privacy-statement/</p>
<h4>CloudFlare CDNJS</h4>
<p>When you have a CDN enabled and have selected the CloudFlare CDNJS option then<br />
the CloudFlare CDNJS service will be used.</p>
<p>Link to service: https://cdnjs.com/libraries/jquery/</p>
<p>For jQuery, CDNJS is powered by CloudFlare.</p>
<p>Link to service: https://www.cloudflare.com/<br />
Terms of Use: https://www.cloudflare.com/website-terms/<br />
Privacy Policy: https://www.cloudflare.com/privacypolicy/</p>
<h4>jsDelivr CDN</h4>
<p>When you have a CDN enabled and have selected the jsDelivr option then the<br />
jsDelivr CDN will be used.</p>
<p>Link to service: https://www.jsdelivr.com/<br />
Privacy Policy: https://www.jsdelivr.com/privacy-policy-jsdelivr-net</p>
<h4>Microsoft CDN</h4>
<p>When you have a CDN enabled and have selected the Microsoft CDN option then the Microsoft CDN will be used.</p>
<p>Link to service: https://docs.microsoft.com/en-us/aspnet/ajax/cdn/overview<br />
Terms of Use: https://docs.microsoft.com/en-us/legal/termsofuse<br />
Privacy Policy: https://privacy.microsoft.com/en-us/privacystatement</p>
<h4>Google CDN</h4>
<p>When you have a CDN enabled and have selected the Google CDN option then the Google CDN will be used.</p>
<p>Link to service: https://developers.google.com/speed/libraries<br />
Terms of Use: https://developers.google.com/terms/site-terms<br />
Privacy Policy: https://policies.google.com/privacy</p>
<p>The Google CDN does not host the jQuery Migrate plugin. When you have a CDN enabled and the Migrate option enabled and have selected the Google CDN option then the jQuery.com CDN will be used for the jQuery Migrate plugin. The Privacy Policy for that CDN is listed earlier in this <code>readme.txt</code> file.</p>
<h3>Hard-coded SRI Hashes</h3>
<p>This plugin includes hard-coded Subresource Identity public hashes for the minified versions of the jQuery core library and the jQuery Migrate Plugin.</p>
<p>For a better understanding of what SRI is and why hard-coding the hashes is a necessary security feature, please see the file <code>SubResourceIntegrity.md</code> in this directory.</p>
<p>The hard-coded hashes can be verified against what is published at the https://code.jquery.com/ website.</p>
<p>Click on the minified link for the same version of jQuery (3.5.1) and a window will pop up with a script tag including the same SRI as what is defined by the <code>PIPJQVSRI</code> constant in <code>versions.php</code>.</p>
<p>Click on the minified link for the same version of jQuery Migrate (3.3.0) and a window will pop up with a script tag including the same SRI as what is defined by the <code>PIPJQMIGRATESRI</code> constant in <code>versions.php</code>.</p>
<h4>CloudFlare CDNJS and jdDeliver CDN</h4>
<p>The minified jQuery Migrate plugin hosted at CloudFlare CDNJS and jsDelivr CDN have the following addition at the end of the JS file that cause their hash to be different:</p>
<pre><code>//# sourceMappingURL=jquery-migrate.min.map
</code></pre>
<p>For this reason, an SRI specific to them is used when CloudFlare CDNJS or jsDelivr CDN is the selected Public CDN.</p>
<p>This SRI value can be obtained from https://cdnjs.com/libraries/jquery-migrate</p>
<p>Mouse over the minified version and from the menu that appears select <em>Copy SRI</em> and the SRI that matches the file they serve will be copied to your clipboard and if the version is the same, it will match what is defined by the <code>PIPJQMIGRATESRI_CDNJS</code> constant in <code>versions.php</code>.</p>
<h3>Public CDN Notes</h3>
<p>As of May 28th, 2020 the following notes apply.</p>
<p>The Microsoft CDN does not yet have current versions of either the core jQuery library or the Migrate plugin. If you select that CDN, the files will be served from your host until the Microsoft CDN has them.</p>
<p>The Google CDN does not host any version of the jQuery Migrate plugin. If you select that option and have the Migrate plugin enabled, that plugin will be served from the jQuery.com CDN.</p>
<h3>Plugin / Theme Compatibility</h3>
<p>This plugin does not set the version for jQuery when registering the script. Unfortunately when registering a script with a version in WordPress, it always applies the query tag <code>?ver=whatever</code> to the end of the resource and doing so with a CDN greatly reduces the odds that a browser will recognize it already has the scripts cached. Some plugins and themes may query for the version of jQuery being used. They should not do so, but some do. They will not get an answer if this plugin has run before they run and they will get the wrong answer if they run before this script has run.</p>
<p>jQuery scripts that depend upon certain versions should query for the capability within the JavaScript rather than depending upon a version specified to WordPress which may not always reflect what is actually served.</p>
<h3>Update Policy</h3>
<p>I will try to update this plugin when new versions of jQuery are released but it may not be as fast as some may like. You can bug me by leaving sending an e-mail to pipfroshpress[AT]gmail[DOT]com.</p>
<p>Please note updates to this plugin with new versions of jQuery will not be pushed until that majority of the supported CDNs have the file. New versions also will not be published if the accompanying Migrate plugin does not give support for scripts written for jQuery 1.12.4.</p>
<p>For the included jQuery Migrate plugin, I am less likely to notice when new versions are available but I do check whenever a new version of jQuery itself is released. Again you can bug me if needed.</p>
<p>Development takes place on github at https://github.com/pipfrosch/pipfrosch-jquery</p>
<p>The <code>master</code> branch will usually be exactly the same as what is distributed through WordPress except it will have a small <code>README.md</code> file. The branch <code>pipjq</code> is where I develop and what is in that branch may not always be stable. When a new release is ready <em>and tested</em> from the <code>pipjq</code> branch, it will be merged with <code>master</code> and then repacked for distribution through the WordPress SVN.</p>
<p>Please use the distribution from WordPress rather than from github unless you are testing. The version from WordPress is audited by more eyes than my github.</p>
<h3>Versioning Scheme</h3>
<p>Versions use the standard <code>Major.Minor.Tweak</code> scheme using integers for each. Code in my github may have a <code>pre</code> appended at the end to indicate is not a released version and should not be used on production systems.</p>
<h4>Tweak bump</h4>
<p>The <strong>Tweak</strong> is incremented by one when a minor change is made, such as adding a new language to the translation support. Generally you can ignore upgrading this plugin when there is just a <em>Tweak</em> bump.</p>
<h4>Minor bump</h4>
<p>The <strong>Minor</strong> is incremented by one when a functional bug is fixed or when an update to jQuery or the jQuery Migrate plugin is made that is not a substantial jQuery change. When <em>Minor</em> is bumped, <em>Tweak</em> will reset to <code>0</code>. Generally you should upgrade when <em>Minor</em> is bumped.</p>
<h4>Major bump</h4>
<p>The <strong>Major</strong> will be incremented when there is an upgrade to jQuery that is significant in nature. Both <em>Minor</em> and <em>Tweak</em> are reset to <code>0</code> when <em>Major</em><br />
is bumped.</p>
<p>Generally you should test an update to <em>Major</em> before updating on a production system just in case some of your jQuery code needs tweaks before deployment.</p>
<h3>Translations</h3>
<p>This plugin is ready for translations but so far does not actually have any. Note that the only strings where translations are beneficial require administrative privileges to see (the Settings). Hopefully translations will soon be made for the benefit of WordPress administrators who have a preferred written language other than English.</p>
<h3>Developers</h3>
<p>If you have a plugin or theme that wants to know about versions, the following options are defined if this plugin is active:</p>
<ul>
<li><code>pipjq_plugin_version</code> defines the plugin version.</li>
<li><code>pipjq_jquery_version</code> defines the jQuery version.</li>
<li><code>pipjq_jquery_migrate_version</code> defines the jQuery Migrate plugin version</li>
</ul>
<p>All three those of those options are defined as strings.</p>
<p>You can also get them directly from the defined constants <code>PIPJQ_PLUGIN_VERSION</code>, <code>PIPJQV</code>, and <code>PIPJQMIGRATE</code> respectively but I do not guarantee that I will continue to specify them with those constant into the long-term future. For example, if I switch to a more OOP approach they may be defined within a class rather than as constants. The options however will always be defined.</p>

<p>Manage <a href="https://jquery.com" rel="nofollow ugc">jQuery</a> and <a href="https://jquery.com/download/#jquery-migrate-plugin" rel="nofollow ugc">jQuery Migrate</a> on a WordPress website, activate a specific jQuery and/or jQuery Migrate version. The ultimate jQuery debugging tool for WordPress</p>
<p><strong>TLDR:</strong> Update jQuery / Remove jQuery Migrate / jQuery Updater and get notified of a jQuery update / manage jQuery</p>
<h3>Features</h3>
<ul>
<li><strong>Remove jQuery Migrate</strong> – if you use plugins which are updated regularly, then you can probably disable / remove jQuery Migrate.</li>
<li><strong>jQuery Updater</strong> – If this plugin is installed and activated, jQuery will be updated when you update this plugin</li>
<li><strong>Select jQuery (Migrate) version</strong> — Activate / select a specific version of jQuery and/or jQuery Migrate.</li>
<li><strong>Debug mode</strong> – Debug mode for developers</li>
<li><strong>Active support</strong> – Active support through <a href="https://wordpress.org/support/plugin/jquery-manager/" rel="ugc">WordPress support forum</a> and <a href="https://github.com/Remzi1993/jquery-manager/issues" rel="nofollow ugc">GitHub issues page</a></li>
</ul>
<p>Note that jQuery Manager requires PHP 5.6+ to run.</p>
<p>When the plugin is activated the latest stable version of jQuery and jQuery Migrate are added to your website. The default is sufficient for most people, however the settings provide a way for you to tweak your jQuery install.</p>
<p>jQuery Manager for WordPress is an open source project and I would like to invite anyone to contribute. The development and issue tracker is located on GitHub, see: <a href="https://github.com/Remzi1993/jquery-manager" rel="nofollow ugc">https://github.com/Remzi1993/jquery-manager</a></p>
<h3>jQuery Updater – checks jQuery version</h3>
<p>This plugin is especially designed to update and keep track of jQuery. When a new version of jQuery is released we update the plugin.</p>
<p>Updating the plugin will updates the jQuery version activated. Updates will be periodic, we also do (small) optimizations to our plugin from time to time.</p>
<p>Keep the plugin activated if you want to be alerted for any jQuery updates.</p>
<h3>Also a Developer / Debugging tool</h3>
<p>Everything should work as intended, you should check your website if everything works fine. If things don’t work, don’t panic. You can deactivate the plugin and return to the state before or tweak it’s settings until everything works as intended.</p>
<p>You should understand that not all themes and/or plugins support the latest jQuery version even with jQuery Migrate turned on, but for you to encounter this is highly unlikely if your theme or plugins are up to date.<br />
This is also a developer/debugging tool.</p>
<p>I will not provide support on debugging your own JavaScript and/or jQuery code. (Only if you like to hire me, of course)</p>
<h3>Reporting problems</h3>
<p>Report bugs, issues, questions and/or feature request on our <a href="https://github.com/Remzi1993/jquery-manager/issues" rel="nofollow ugc">GitHub issues page</a>.</p>
<p>I will only provide support on issues caused by this plugin, not your own JavaScript and/or jQuery code. (Again, I will provide paid support or fix all your issues if you’re willing to hire me to debug and/or optimize your website)</p>
<p>If you run into any bugs, turning this plugin off (by deactivation the plugin) will fully deactivate everything and return your website to it`s original state.</p>
<h3>Translations</h3>
<p>This plugin is not ready for translation. Plugin Internationalization (i18n) will eventually happen, see: <a href="https://github.com/Remzi1993/jquery-manager/issues/14" rel="nofollow ugc">https://github.com/Remzi1993/jquery-manager/issues/14</a></p>
<h3>Additional Info</h3>
<p><strong>Idea Behind / Philosophy:</strong> It began as a plugin internally at our company, we would uses jQuery Updater plugin and this plugin was buggy and slow. That’s why we decided to fork this plugin and create our own WP plugin.</p>
<p>I think this plugin solves a major shortcoming in WordPress and gives you finite control over jQuery (giving you control which version you want to use).</p>
