How to get the value of an id from the url-jquery

Question

url: testPage?id=67346756384/indexList

how to get the location of the id from the above url? I tried this:

getIdLocation = $(location).attr("href");
id = getIdLocation.substring(getIdLocation.lastIndexOf("/") + 1);

but that gets me "indexList". I need the id.Any ideas?? Thanks!

I have used this function, it works great.

It will be something like this for your case, pretty simple:

var id = GetURLParameter('id');

Full code from the link:

function GetURLParameter(sParam){
    var sPageURL = window.location.search.substring(1);
    var sURLVariables = sPageURL.split('&');
    for (var i = 0; i < sURLVariables.length; i++)
    {
        var sParameterName = sURLVariables[i].split('=');
        if (sParameterName[0] == sParam)
        {
            return sParameterName[1];
        }
    }
}

Although, I prefer to pass the url as a parameter. It will be easier to write unit tests for that.

Use the first and second parameters of substr to designate the start and length of the string to be extracted:

var id = str.substring(str.lastIndexOf("=")+1,str.lastIndexOf("/"));
