在所有AJAX请求完成后采取的措施 [英] action after all of AJAX request finish

问题描述

我试图在ajax之后执行操作，但是我不能

I trying to execute an action after the ajax, but I can't

$.each(LinkUnique,function(i){
        $.ajax({
            type: "POST",
            url: 'http://xxxx.net/',
            success: function(msg){
                if(msg.indexOf("http://") !=-1)
                    link = link+msg+"\n";
            }
        });
    });

在脚本之后执行下一个操作:

Here the next action after the script:

alert("Finish");

async: false不是一个好的选择，因为我的页面完全停止了.

async: false isn't a good option because my page stops completely.

推荐答案

您可能正在尝试等待所有ajax调用完成，因为您正在执行多个操作:

You're probably trying to wait until all the ajax calls have completed, as you're doing multiple :

var xhrs = [],
    link = '';

$.each(LinkUnique,function(i){
    var xhr = $.ajax({
                  type: 'POST',
                  url : 'http://xxxx.net/'
              }).done(function(msg) {
                  if(msg.indexOf("http://") !=-1)
                      link = link+msg+"\n";
              });

    xhrs.push(xhr);
});

$.when.apply($, xhrs).then(function() {
    alert(link);
});
