Need to generate an json array, then loop through the values.

Question

Hi,

I need to create some sort of a state for a bunch of elements on a page. The stats can be 1 or -1.

Now on the server side I will generate a JSON array and put it in my .aspx page like this:

var someArray = { 100:-1, 1001:1, 102:1, 103:-1 }

How do I loop through each value now in javascript?

BTW, is my JSON array format correct?

Answer 1

Note that someArray is a misnomer as it is actually an Object. To loop through it, though:

for(key in someArray) {
    alert(someArray[key]);
}

As far as whether it is valid, the above works for me but I believe technically keys should be strings:

{
    "100": -1,
    "1001": 1,
    "102": 1,
    "103": -1 
}
