How to use jQuery ajax to check if file exists in JS array?

I have an array urlResult which collects the href attribute of all a elements on a component. Looks like:

All I need to do is use jQuery $.ajax() method to check against those URL's and in each callback do something if there is success or failure. So I was thinking of something like:

$.ajax({
    url: urlResult[i] // somehow use dynamic variable?
    type:'HEAD',
    error: function()
    {
        //file not exists
    },
    success: function()
    {
        //file exists
    }
});

I just need some guidance on how to dynamically include urlResult variable and pass each index to url property in ajax call.
