jQuery html() example

jQuery html() is used to get the html contents of the first element of the matched elements; While html(‘new html content’) is used to replace or set the html contents of all the matched elements.

For example, two div elements that contains same class name “AClass”.

<div class="AClass">ABC 1</div>
<div class="AClass">ABC 2</div>

1. $(‘.AClass’).html()

This will get the “ABC 1” only, the second matched element “ABC 2″ will be ignore.

2. $(‘.AClass’).html(‘This is new text‘)

This will replace the html content of all the matched elements.

<div class="AClass"><b>This is new text</b></div>
<div class="AClass"><b>This is new text</b></div>
