JQuery Developer Interview Question:

What is the use of jquery .each() function?

Submitted by: Administrator

Basically, the jQuery .each() function is used to loop through each element of the target jQuery object. Very useful for multi element DOM manipulation, looping arrays and object properties.

Example:
In this example alert box will open 3 times because dom contain 3 <li> tags
<script>
$(document).ready(function(){
$("button").click(function(){
$("li").each(function(){
alert($(this).text())
});
});
});
</script>

<ul>
<li>Coffee</li>
<li>Milk</li>
<li>Soda</li>
</ul>
