最好使用独立代码.....

var xhrQueue = []; 

$(document).ajaxSend(function(event,jqxhr,settings){
    xhrQueue.push(jqxhr); //alert(settings.url);
});

$(document).ajaxComplete(function(event,jqxhr,settings){
    var i;   
    if((i=$.inArray(jqxhr,xhrQueue)) > -1){
        xhrQueue.splice(i,1); //alert("C:"+settings.url);
    }
});

ajaxAbort = function (){  //alert("abortStart");
    var i=0;
    while(xhrQueue.length){ 
        xhrQueue[i++] .abort(); //alert(i+":"+xhrQueue[i++]);
    }
};

把我的帽子扔进去。提供针对xhrPool数组的中止和删除方法，并且不容易出现ajaxSetup覆盖问题。

/**

 */
jQuery.xhrPool = [];

/**
 * jQuery.xhrPool.abortAll
 * 
 * Retrieves all the outbound requests from the array (since the array is going

 * perform the abortion. Doing so will trigger the ajaxComplete event against

 * @access public

 */
jQuery.xhrPool.abortAll = function() {
    var requests = [];
    for (var index in this) {
        if (isFinite(index) === true) {
            requests.push(this[index]);
        }
    }
    for (index in requests) {
        requests[index].abort();
    }
};

/**
 * jQuery.xhrPool.remove
 * 
 * Loops over the requests, removes it once (and if) found, and then breaks out
 * of the loop (since nothing else to do).
 * 
 * @access public
 * @param  Object jqXHR
 * @return void
 */
jQuery.xhrPool.remove = function(jqXHR) {
    for (var index in this) {
        if (this[index] === jqXHR) {
            jQuery.xhrPool.splice(index, 1);
            break;
        }
    }
};

/**
 * Below events are attached to the document rather than defined the ajaxSetup
 * to prevent possibly being overridden elsewhere (presumably by accident).
 */
$(document).ajaxSend(function(event, jqXHR, options) {
    jQuery.xhrPool.push(jqXHR);
});
$(document).ajaxComplete(function(event, jqXHR, options) {
    jQuery.xhrPool.remove(jqXHR);
});

以下是我目前正在使用的方法。

$.xhrPool = [];
$.xhrPool.abortAll = function() {
  _.each(this, function(jqXHR) {
    jqXHR.abort();
  });
};
$.ajaxSetup({
  beforeSend: function(jqXHR) {
    $.xhrPool.push(jqXHR);
  }
});

注意:_。js中的每一个都存在，但显然不是必需的。我只是懒惰，我不想把它改为$.each()。8页

给每个xhr请求一个唯一的id，并在发送之前将对象引用存储在一个对象中。 在xhr请求完成后删除引用。

随时取消所有请求:

$.ajaxQ.abortAll();

返回被取消的请求的唯一id。仅用于测试目的。

工作职能:

$.ajaxQ = (function(){
  var id = 0, Q = {};

  $(document).ajaxSend(function(e, jqx){
    jqx._id = ++id;
    Q[jqx._id] = jqx;
  });
  $(document).ajaxComplete(function(e, jqx){
    delete Q[jqx._id];
  });

  return {
    abortAll: function(){
      var r = [];
      $.each(Q, function(i, jqx){
        r.push(jqx._id);
        jqx.abort();
      });
      return r;
    }
  };

})();

返回一个具有单个函数的对象，该对象可用于在需要时添加更多功能。

我发现对多个请求来说太简单了。

步骤1:在页面顶部定义一个变量:

  xhrPool = []; // no need to use **var**

step2:在所有ajax请求中设置beforeSend:

  $.ajax({
   ...
   beforeSend: function (jqXHR, settings) {
        xhrPool.push(jqXHR);
    },
    ...

第三步:在任何需要的地方使用它:

   $.each(xhrPool, function(idx, jqXHR) {
          jqXHR.abort();
    });

有一个虚拟的解决方案，我用它来中止所有ajax请求。这个解决方案是重新加载整个页面。如果您不喜欢为每个ajax请求分配ID，并且在for-loop中进行ajax请求，则此解决方案很好。这将确保所有ajax请求都被杀死。

location.reload();
