    • 嗨它类似于使用jQuery中止Ajax请求，无论如何这可以帮助你

     var ab = $.ajax({  type: "GET",  url: url,  success: function(m)  {    alert( "success");  } });

//kill the request
ab.abort()

    将从ajax请求返回的promise界面存储在global variable ，并在取消点击时abort它

    var result = $.ajax({  type: "GET",  url: url,  success: function(m)  {    alert( "success");  } });


$('#cancel').click(function() {
    result.abort();
});

    var request= $.ajax({  type: "GET",  url: url,  success: function(m)  {    alert( "success");  } });


$('#cancel').click(function() {
    request.abort();
});

    this will abort the request from the client(browser) side but note : if the server has already received the request, it may continue processing the request (depending on the platform of the server) even though the browser is no longer listening for a response. There is no reliable way to make the web server stop processing a request that is in progress.
