javascript - Find out how long an Ajax request took to complete

Question

What is a good way to find out how long a particular $.ajax() request took?

I would like to get this information and then display it on the page somewhere.

ANSWER??::::

I'm new to javascript, this is the best that I could come up with if you don't want to inline the "success" function (because it will be a much bigger function) Is this even a good way to do this? I feel like I'm over complicating things...:

makeRequest = function(){
    // Set start time
    var start_time = new Date().getTime();

    $.ajax({ 
        async : true,
        success : getRquestSuccessFunction(start_time),
    });
}

getRquestSuccessFunction = function(start_time){
    return function(data, textStatus, request){
        var request_time = new Date().getTime() - start_time;
    }
}

@codemeit is right. His solution looks something like the following using jQuery for the ajax request. This returns the request time in milliseconds.

var start_time = new Date().getTime();

jQuery.get('your-url', data, function(data, status, xhr) {
        var request_time = new Date().getTime() - start_time;
});
