回答1:

you can do this for instance it your ajax calling function

var call = $.ajax({
    type: "POST",
    url: "mywebservice.aspx",
    data: "some data you are passing ",
    success: function(msg){
      // do stuff on sucess
    }
});

and the you can call this to kill the process.

call.abort()
