在页面重定向之前将数据发布到服务器异步 [英] Posting data to server async just before page redirect

问题描述

这似乎是一个普遍的问题，但我找不到相关的主题 - 请直接告诉我，如果我错过了这里。

我们正在使用某种点击跟踪器到我们的网站。
此跟踪器在用户点击链接时接到呼叫，我们希望将某些数据填充到不同的服务器，并让用户继续点击链接。

因为我不想在这里等待服务器响应 - 我不等待对这个ajax调用的响应。
但发生的是我失去了这个呼叫，它永远不会到达服务器。
执行此操作的正确方法是什么？

我正在使用top.window.location.href = url;因为我有时在iframe中打开。

  function onClick（url，clickedFrom）{
 var testClick = ServerHost + 点击 
 var dataObject = buildCommonData（）; 
 
 $ .ajax（{
 dataType：'post'，
 contentType：text / json; charset = utf-8，
 data：dataObject，
 url：testClick，
 async：true，
 success：function（response）{
 top.window.location.href = url; 
 
}， 
 
}）; 
 top.window.location.href = url; 
 
返回false; 
 
  

解决方案

删除第二个 top.window.location.href = url; ...这是打破你的 $。ajax（）调用...和 return false 永远不会到达。

考虑使用 setTimeout 和 成功： $。ajax（） call！



你可以在这里加倍你的方法，并保留第二个 top.window.location.href 调用，但将它放在 setTimeout 块中，以防出现 $。ajax（）延迟。

这样， $。ajax（）调用应该首先发生，但如果没有，至少用户不会在延迟 $。ajax（）调用的服务器故障时发生延迟。

It seems like a common problem, but I couldn't find related threads - please direct me if I missed something here.

we are using some sort of click tracker to our website. this tracker is getting calls when the user click on a link, we want to populate certain data to a different server, and let the user continue to the clicked url.

As I do not want to wait for the server response here- I am not waiting for response to this ajax call. but what happens is the I lose this call and it never gets to the server. What is the correct way to perfrom this action?

I am using top.window.location.href = url; as I sometimes get opened in an Iframe.

function onClick(url, clickedFrom) {
        var testClick = ServerHost + "click";
        var dataObject = buildCommonData();

        $.ajax({
            dataType: 'post',
            contentType: "text/json; charset=utf-8",
            data: dataObject,
            url: testClick,
            async: true,
            success: function (response) {
                top.window.location.href = url;

            },

        });
        top.window.location.href = url;

        return false;
    }

解决方案

Remove the second top.window.location.href = url; ... that is clobbering your $.ajax() call... and return false is never reached.

Consider using setTimeout and success: on the $.ajax() call!

You can double-up your approach here, and keep the second top.window.location.href call, but put it in a setTimeout block, in case there is an $.ajax() delay.

This way, the $.ajax() call should happen first, but if not, at least the user is not delayed if/when there is a server glitch that hangs up the $.ajax() call.
