Purpose

A basic AjaxLoader wrapper that inserts AJAXed-in content.

Executing WET plugin on AJAXed-in content

/**

(function( $, document, wb ) {
	"use strict";
	$('#mycontainer').on( "wb-contentupdated", function( event, data ){
		// "data.ajax-type" contains the insersion method [after, append, before, prepend, replace]
		// "data.content" contains the
		var $elm = $(event.currentTarget);
		$elm
			.find( wb.allSelectors )
				.addClass( "wb-init" )
				.filter( ":not(#" + $elm.attr( "id" ) + " .wb-init .wb-init)" )
					.trigger( "timerpoke.wb" );
		/*
		 * Since we are working with events we want to ensure that we are being
		 * passive about our control, so returning true allows for events to always
		 * continue
		 */
		return true;
	});
})( jQuery, document, wb );

Be careful to not execute it on every data-ajax container to avoid a possible recursive self calling situation.

Working example

How to implement

  1. Add one of the following data-ajax attributes to an element, with the attribute value being the URL of the content to AJAX in:

    • data-ajax-after: Insert content after the element

      <section data-ajax-after="ajax/data-ajax-extra-en.html">
	...
</section>

    • data-ajax-append: Insert content at the end of the element

      <section data-ajax-append="ajax/data-ajax-extra-en.html">
	...
</section>

    • data-ajax-before: Insert content before the element

      <section data-ajax-before="ajax/data-ajax-extra-en.html">
	...
</section>

    • data-ajax-before: Insert content at the start of the element

      <section data-ajax-prepend="ajax/data-ajax-extra-en.html">
	...
</section>

    • data-ajax-before: Replace the element with the content

      <section data-ajax-replace="ajax/data-ajax-extra-en.html">
	...
</section>
  2. Optional (v4.0.12+): Filter the content using the URL hash (ajax/data-ajax-filter-en.html#filter-id) or a selector (ajax/data-ajax-filter-en.html .filter-selector).

Configuration options

Option Description How to configure Values
Overlay type Configure the origin and destination of the content to AJAX in. Add the configuration attribute to the affected element with the value being the URL of the content to AJAX in.
data-ajax-after:
Insert the content after the element.
data-ajax-append:
Insert the content at the end of the element.
data-ajax-before:
Insert the content before the element.
data-ajax-prepend:
Insert the content at the start of the element.
data-ajax-replace:
Replace the element with the content.
url Configure the origin of the content to AJAX in. data-wb-ajax='{ "url": "location/of/ajax/fragment/file.html", "type": "replace" }' The value being the URL of the content to AJAX in.
type Configure how the destination of the content will be inserted. data-wb-ajax='{ "url": "location/of/ajax/fragment/file.html", "type": "replace" }' Be one of the valid value listed.
after
Insert content after the element
append
Insert content at the end of the element
before
Insert content before the element
replace
Replace content inside the element
prepend
Insert content at the start of the element
nocache Prevent caching. Prior using the functionality, use the various caching strategies that can be set and communicated through http header from your server, as defined in section 5 of RFC7234. Also, please note that some server may not like to have an query appended to his url and you may get an HTTP error like "400 Bad Request" or "404 Not Found". Like a page served by a domino server will return 404 error if the query string do not start with "?open", "?openDocument" or "?readForm". data-wb-ajax='{ "url": "location/of/ajax/fragment/file.html", "type": "replace", "nocache": true }' or data-wb-ajax='{ "url": "location/of/ajax/fragment/file.html", "type": "replace", "nocache": "nocache" }'
Default
The browser will manage the cache based on how the server has sent the file.
true
Boolean, Use the same cache buster id for the user session. Clossing and opening the tab should generate a new cache busting id.
nocache
String, A new id is generated everytime the file is fetched
nocachekey Prevent caching. Optional, it defined what query parameter name to use for the cache busting. data-wb-ajax='{ "url": "location/of/ajax/fragment/file.html", "type": "replace", "nocache": true, "nocachekey": "wbCacheBust" }'
Default
Will use "wbCacheBust" for the parameter name.
String
URL pre-encoded string

Events

Event Trigger What it does
wb-init.wb-data-ajax Triggered manually (e.g., $( "[data-ajax-after], [data-ajax-append], [data-ajax-before], [data-ajax-prepend], [data-ajax-replace]" ).trigger( "wb-init.wb-data-ajax" );). Used to manually initialize the Data Ajax plugin. Note: The Data Ajax plugin will be initialized automatically unless the required markup is added after the page has already loaded.
wb-ready.wb-data-ajax (v4.0.5+) Triggered automatically after the content has been AJAXed in. Used to identify where content has been AJAXed in by the plugin (target of the event) and to pass along how the content was included ("after", "append", "before", "prepend" or "replace"). 
$( document ).on( "wb-ready.wb-data-ajax", "[data-ajax-after], [data-ajax-append], [data-ajax-before], [data-ajax-prepend], [data-ajax-replace]", function( event, ajaxType ) {
});
$( "[data-ajax-after], [data-ajax-append], [data-ajax-before], [data-ajax-prepend], [data-ajax-replace]" ).on( "wb-ready.wb-data-ajax", function( event, ajaxType ) {
});
wb-ready.wb (v4.0.5+) Triggered automatically when WET has finished loading and executing. Used to identify when all WET plugins and polyfills have finished loading and executing. 
$( document ).on( "wb-ready.wb", function( event ) {
});
wb-contentupdated Triggered automatically when data-ajax has finished to load the response. Use to perform a secondary action upon ajax content is loaded 
$('#mycontainer').on( "wb-contentupdated", function( event, data ){
});
