中止以前運行的Ajax請求

Question

是否可以中止先前運行的Ajax請求？

var xhr = $.ajax({ 
    type: "POST", 
    url: "some.php", 
    data: "name=John&location=Boston", 
    success: function(msg){ 
     alert("Data Saved: " + msg); 
    } 
});

嘗試這樣的事情

 $(document).ready(function(){ 
      var xhr; // global object 

      function your_function() { 
       if(xhr && xhr.readystate != 4){ 
        xhr.abort(); 
       } 

       xhr = $.ajax({ 
        type: "POST", 
        url: "some.php", 
        data: "name=John&location=Boston", 
        success: function(msg){ 
         alert("Data Saved: " + msg); 
        } 
       }); 
      } 
     });
