The purpose of this plugin is to minimize page load time and resource usage by updating the page title and content only rather then reloading the entire webpage. 
The new contents and titles are fetched by ajax calls.
Restriction: 
As the rest of the page like header including all styles and scripts, footer and sidebars are not affected, you should only use this to switch between pages with the same overall layout and requirements.
You can enter shortcodes in the page content that will show up as a button or a text link. 
When activating the link, the pages title and content will be replaced by the title and content of the specified page.
There are four possible independant arguments to the shortcode: 
– page (required). This can be the page title or the page id. 
– text (optional). The button text or textlink text. 
– title-elm (optional). The title element id or class if it is not the default as entered on the settings page. 
– content-elm (optional). The content element id or class if not default.
Examples: [pla page=”Tet page”] [pla page=”5″ text=”Go to the testpage”] [pla page=”My Page” content-elm=”#my-div”]

Page Load Ajax

This plugin enables the use of shortcodes that create links to replace the current page content with the content of another page.

With ZM Ajax Login & Register, you can create a custom login and registration page. No need for any custom post types, just create a normal WordPress page, add your own custom logo, text, and use the following shortcode <code>[ajax_login]</code>, <code>[ajax_register]</code>.
From the settings you can assign login and register modal boxes to menu items, and add a redirect URL. By assigning the login and register modals to menu items users will be able to click menu items, will display a single login or register form in a modal without any post content. Once the users login they can be redirected to a custom page, for example: “dashboard”, or “welcome”.
Now your visitors can login or register from the page you’ve set-up.
Each form has pre-set styling options and uses AJAX. From the settings you can choose either; stacked (default) or wide styling. Additional styling you can be achieved by adding your custom CSS or using one of the available hooks. 
Feel free to contact us and will add any additional hooks you need. The forms use AJAX to verify that the username and email are valid and are not already in use.
If you’ve enabled the Facebook login or register, from your settings, the Facebook button will display in the form. Each user that logins with Facebook will be register as a “subscriber” and their Facebook profile picture will be used as their avatar.
