Question

I have the following javascript variable:

var myList =
    {
        itemA: 0,
        itemB: 1,
        itemC: 2,
        itemD: 3,
        itemE: 4
    };

I have the value of the variable, ie 0, 1, 2 etc and need to find the corresponding key to it ie if I have 2, the key would be itemC.

How can I do this with javascript?

    var myList =
    {
        itemA: 0,
        itemB: 1,
        itemC: 2,
        itemD: 3,
        itemE: 4
    };

$.each(myList,function(index,value){
    if(value == 2){ alert(index); }
});
