如何从 jquery GET 搜索结果

发布于 2024-11-07 22:28:05 字数 621 浏览 0 评论 0原文

我在调查脚本中 get 的结果时遇到了一些问题。我得到了以下代码来检查用户是否仍处于登录状态：

$.get("nowhereGet", function(result){
    if($(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 get 中返回 result 中的一个 html 页面。如果用户已注销，将返回一个包含 id="loginInput" 元素的不同页面。
我以为上面的方法可以解决问题，但没有爱。我做错了什么？
有没有比使用随机 get ping 服务器更好的方法？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

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";
    }
    });

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

$('#result').get(......); ???

更新
因此元素 #result 将具有 #loginInput 具有的内容

$('#result').load('login.php #loginInput');

否则，请查找 json 选项，因为您的方式这样做，有点乱

除非你正在寻找这个

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

$('#result').get(......); ???

UPDATE
so the element #result would have what ever the #loginInput has

$('#result').load('login.php #loginInput');

Otherwise look for a json option because the way you are doing it, its kinda messy

Unless you are looking for this

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