JQuery Prepend

From WikiOD

Prepending an element to a container[edit | edit source]

Solution 1:

 $('#parent').prepend($('#child'));

Solution 2:

 $('#child').prependTo($('#parent'));

Both solutions are prepending the element #child (adding at the beginning) to the element #parent.

Before:

<div id="parent">
  <span>other content</span>
</div>
<div id="child">

</div>

After:

<div id="parent">
  <div id="child">

  </div>
  <span>other content</span>
</div>

Prepend method[edit | edit source]

prepend() - Insert content, specified by the parameter, to the beginning of each element in the set of matched elements.

1. prepend( content [, content )]

// with html string
jQuery('#parent').prepend('<span>child</span>');
// or you can use jQuery object
jQuery('#parent').prepend($('#child'));
// or you can use comma seperated multiple elements to prepend
jQuery('#parent').prepend($('#child1'),$('#child2'));

2. prepend(function)

JQuery version: 1.4 onwards you can use callback function as the argument. Where you can get arguments as index position of the element in the set and the old HTML value of the element. Within the function, this refers to the current element in the set.

jQuery('#parent').prepend(function(i,oldHTML){      
     // return the value to be prepend
     return  '<span>child</span>';
});
