Question

I have this Object:

Object ->

Content: <h1>some html</h1>
Url : A url

Now i’m using this code to work out if a certain URL exists in the current object:

var inURLArray = function(url, array) {
        for(var i in array) {
            if(array[i].url && array[i].url == url)
                return true;
            }
                return false;
        };

So i pass it the url i’m looking for and the object i’m looking in. I can then do var found = inURLArray('http://google.com', tabArray); what could i do if i find the URL i’m looking for to get the content in the same Object. The array is called tabArray. I’m using jQuery/Javascript!

I should say, i dont really mind how i access the content, ie. if its stored in a variable or alerted!

You could replace the boolean function by one that simply returns the object found, or null if there isn’t one:

var findInArrayByUrl = function(url, array) 
{
    for(var i in array) 
    {
        if(array[i].url && array[i].url == url)
        {
            return array[i];
        }
    }
    return null;
};
