Problem with successive ajax call & resolve it?

I was working on a mobile application using phonegap recently. I was making calls to the API to fetch data. I found that before completing a request call, another request was made. So, there were some deadlock of request calls.

Hence, we need to remove the request calls that are not used any longer. We need to detect whether the request is completed or not.


The below is the code block to stop ajax request calls. The $.ajax request returns an object. We check this object, whether any request call is running or not. If one request call is there, then we terminate it using the abort function.

var req = null;

function sendRequest (text)
{
        // Check for pending request & cancel it
        if (req) req.abort ();

        req = $.ajax ({
                // various options..
                success: function (data)
                {
                        // Process data
                        ...
                        // reset request
                        req = null;
                }
        });
}
