window.open与ajax的同步

有个需求，在ajax提交新帖子后，要打开刚发的帖子：

$.ajax({            type: "POST",            url: "list.php?action=addArticle",            dataType: "json",            data: data,                   success: function (msg) {   window.open('http://baidu.com');//这里是模拟打开刚发的帖子}});

谁知道，怎么都打不开

把ajax改为同步的，就可以了：

            async: false

  $.ajax({            type: "POST",            url: "list.php?action=addArticle",            dataType: "json",            data: data,            async:false, //同步            success: function (msg) {   window.open('http://baidu.com');//这里是模拟打开刚发的帖子}});
