检查 Javascript 后重定向不起作用

Question

From my below script i request the status from index2.html.从我下面的脚本中，我从 index2.html 请求状态。

My http://test1.info/portal/#portal cannot be reached (Chrome) or displayed (IE).我的http://test1.info/portal/#portal无法访问 (Chrome) 或显示 (IE)。 Since the URL is "404" or not reached it is not redirecting it to index3.html由于 URL 是“404”或未到达，因此不会将其重定向到index3.html

 function website() { var req = new XMLHttpRequest(); req.open('GET', 'http://mytest.info/index2.html', true); alert(req.status); req.send(); if (req.status != "200" || "404") { window.location.href = "http://test1.info/portal/#portal"; } else { alert("123"); alert(req.status); window.location.href = "http://test.example.info/index3.html"; } }

 <body onload="website()" >

Where am I doing it wrong?我哪里做错了？

There are some typos in your code:您的代码中有一些拼写错误：

there is a ) in your body tag你的body标签中有一个)
you haven't closed your body tag你还没有关闭你的body标签
in the if condition you used or , which doesn't exist in JS (it's || ), but in your case your logic should be the following: req.status != "200" && req.status != "404"在你使用的if条件or ，JS 中不存在（它是|| ），但在你的情况下，你的逻辑应该如下： req.status != "200" && req.status != "404"

Once you fix these issues, your code should work:解决这些问题后，您的代码应该可以正常工作：

 function website() { var req = new XMLHttpRequest(); req.open('GET', 'http://mytest.info/index2.html', true); alert(req.status); req.send(); if (req.status != "200" && req.status != "404") { window.location.href = "http://test1.info/portal/#portal"; } else { alert("123"); alert(req.status); window.location.href = "http://test.example.info/index3.html"; } }

 <body onload="website()"></body>
