foreach() loop in javascript...?!?

[gilly914]

Is there some kind of loop in Javascript that's equivalent to the foreach() loop in PHP???

foreach ( $AREA as $AreadID => $AreaName) {
        // do something //
}

I don't recall how to do it. In JavaScript, I'm not sure that one can have arrays with indices other than incrementing numbers; I would say no, but that is just a guess.

I don't think I understand what you mean...?

What is the code you gave me supposed to do? and how can it help me, in my case?

[Dr. Script]

PHP can have different keys or indices for each element. Terefore, you could something like: $arr['car'];, if you defined in your array "car" => "Honda" .

For a JS solution, see below.

I'm sure this will help me some time in the future...

well... you can indeed have arrays with associative indices in javascript, means not only numbers. you can even have multi-dimensional arrays...

<script type="text/javascript">
    var aCharts = new Array();
    aCharts['classes']       = new Array( 'notselected', 'selected' );
    aCharts['base_url']      = '***************';
    
    aCharts['images']        = new Array();
    aCharts['images'][0]     = '1D';
    aCharts['images'][1]     = '3M';
    aCharts['images'][2]     = '6M';
    aCharts['images'][3]     = '1Y';
    aCharts['images'][4]     = '3Y';
</script>

well and for the foreach...
you have to use a for loop in this way:

    for( var sIndex in aArray ) {
        var sValue = aArray[sIndex];

        ....
    }

To see the whole thing in action i'm attaching a sample file with just dumps the aCharts array.
