停止jQuery中的所有活动ajax请求

我有一个问题，当提交表单时，所有活跃的ajax请求失败，并触发错误事件。

如何在jQuery中停止所有活动ajax请求而不触发错误事件?

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。

/**
 * Ajax Request Pool
 * 
 * @author Oliver Nassar <onassar@gmail.com>
 * @see    http://stackoverflow.com/questions/1802936/stop-all-active-ajax-requests-in-jquery
 */
jQuery.xhrPool = [];

/**
 * jQuery.xhrPool.abortAll
 * 
 * Retrieves all the outbound requests from the array (since the array is going
 * to be modified as requests are aborted), and then loops over each of them to
 * perform the abortion. Doing so will trigger the ajaxComplete event against
 * the document, which will remove the request from the pool-array.
 * 
 * @access public
 * @return void
 */
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);
});

其他回答

var Request = {
    List: [],
    AbortAll: function () {
        var _self = this;
        $.each(_self.List, (i, v) => {
            v.abort();
        });
    }
}
var settings = {
    "url": "http://localhost",
    success: function (resp) {
        console.log(resp)
    }
}

Request.List.push($.ajax(settings));

每当您想要中止所有ajax请求时，只需调用这一行

Request.AbortAll()

下面的代码片段允许您维护一个请求列表(池)，并在需要时中止它们。最好放在html的<HEAD>中，在任何其他AJAX调用之前。

<script type="text/javascript">
    $(function() {
        $.xhrPool = [];
        $.xhrPool.abortAll = function() {
            $(this).each(function(i, jqXHR) {   //  cycle through list of recorded connection
                jqXHR.abort();  //  aborts connection
                $.xhrPool.splice(i, 1); //  removes from list by index
            });
        }
        $.ajaxSetup({
            beforeSend: function(jqXHR) { $.xhrPool.push(jqXHR); }, //  annd connection to list
            complete: function(jqXHR) {
                var i = $.xhrPool.indexOf(jqXHR);   //  get index for current connection completed
                if (i > -1) $.xhrPool.splice(i, 1); //  removes from list by index
            }
        });
    })
</script>

安迪的代码有一些问题，但它给了我一些很好的想法。第一个问题是，我们应该弹出任何成功完成的jqXHR对象。我还必须修改abortAll函数。下面是我最终的工作代码:

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

我不喜欢ajaxComplete()做事情的方式。无论我如何尝试配置. ajaxsetup，它都不工作。

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();
    });

这里是一个复制过去的函数，刷新所有的ajax调用。 fillCompteList()和fetchAll()必须返回ajax对象:

function fillCompteList() {
   return $.ajax({
            url: 'www.somewhere.com' ,
            method: 'GET',
            success: function(res){
            ...
          });

然后用这个

var xhrPool = [fillCompteList(inisial), fetchAll(params)] ;//old
function refrechAllUsing(SOME , params){
    xhrPool.forEach(function(request){
        request.abort();
    });
    xhrPool = [fillCompteList(SOME), fetchAll(params)]//new with other parameters
    Promise.all(xhrPool).then(() => {
        $('#loadding').undisplay();//remove the loadding screen 

    }).catch(() => {
        warning("Some problem happened");
        $('#loadding').undisplay();//remove the loadding screen 
    });
}
