loop through elements in an array
Description
.each() works with objects, array-like objects, and arrays.
$.each() is zero-based and accepts two arguments: the collection to iterate over and a callback function.
The callback function accepts the arguments: the index currently operated on and the element value.
Example
The following code illustrates using $.each() to iterate over the members of a simple array:
<!DOCTYPE html>
<html>
<head>
<script type="text/javascript" src="jquery.js"></script>
<script type="text/javascript">
$.ready(function(){<!-- w w w. ja va2 s . co m-->
var numArray = [1,2,3,4];
$.each( numArray, function( index, value ){
value = value * 2;
console.log( "index is:"+index+" new value is:" + value );
});
});
</script>
</head>
<body>
</body>
</html>
