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>
