如何从jQuery GET搜索结果 [英] How do I search results from jquery GET

问题描述

我在调查脚本中get的结果时遇到了一些问题.我得到以下代码来检查用户是否仍在登录:

I'm having a bit of a problem investigating the result from my get in my script. I got the following code to check if a user is still logged in:

$.get("nowhereGet", function(result){
    if($(result).find('[id="loginInput"]'))
    {
        //HTML is in the response then we have been logged out and the user needs to go to 
        window.location.href = "login";
    }
    });

现在，如果用户已登录，Struts将从我的获取中返回result中的一个html页面.如果用户已注销，则将返回一个页面，其中包含id="loginInput"元素.
我以为上面可以解决问题，但是没有爱.我在做什么错?
有没有比使用随机get ping服务器更好的方法了?我需要一种使用ajax执行此检查的方法，并且注销时完成的任何get或post都会被拦截，结果将是登录页面而不是预期页面

Now if the user is logged in Struts will return one html-page in result from my get. If the user has been logged out different page will be returned one with and element id="loginInput"in it.
I thought the above would do the trick but no love. What am I doing wrong?
Is there a better way to do this than to ping the server with a random get? I need a method that performes this check using ajax and any get or post done while logged out will get intercepted and the result will be the login-page instead of the intended page

推荐答案

我找到了其他解决方案，并在史蒂文·贝尼特斯(Steven Benitez)的帮助下，使它正常工作.点击链接以获取更多信息，但总之，我让拦截器代替了它.如果某个路径/动作被调用，拦截器将返回一个文本流，我可以从脚本中读取该文本流.

I found an other soloution and with help from Steven Benitez I got it working. Follow the link for more information but in short I let my interceptor do the work instead. If a certain path/action is called the interceptor will return a text stream that I can read from my script.
