Parameters

text

factoryFunction
a function(listItem, listIndex) that will be invoked for each list element to create the nodes:
listItem
The list element that will receive the new children.
listIndex
The index of the list element that will receive the new children.
(callback return value)
The node(s) to be added to the list element. Can be either a string for a text node, an HTML element or a list containing strings and/or DOM nodes. If a function is returned, it will be invoked recursively with the same arguments.
(return value)

Description

Adds the given node(s) as children to the list's HTML elements. Unlike add(), the new nodes will be the first children and not the last. If a string has been given, it will be added as text node. DOM nodes will be added directly. If you pass a list, all its elements will be added using the rules above.

When you pass a DOM node and the target list has more than one element, the original node will be added to the first list element, and clones to all following list elements.

EE(), HTML() and clone() are compatible with addFront() and can help you create new HTML ndoes.

Example

Using the following HTML: 

<div id="comments">Here is some text.<br/></div>
Add a text to the div: 
$('#comments').addFront('Some additional text. ');
This results in: 
<div id="comments">Some additional text. Here is some text.<br/></div>

Example

Using the following HTML: 

<ul id="myList">
  <li>First list entry</li>
  <li>Second list entry</li>
</ul>
The following Javascript adds an element to the list: 
$('#myList').addFront(EE('li', 'My extra point'));
This results in 
<ul id="myList">
  <li>My extra point</li>
  <li>First list entry</li>
  <li>Second list entry</li>
</ul>

Example

Use a list to add several elements at once: 

$('#comments').addFront([
     EE('br'),
     'Some text',
     EE('span', {'className': 'highlight'}, 'Some highlighted text')
]);
