使用javascript和GET变量刷新页面 [英] Refresh the page with javascript and GET variables

问题描述

<script type="text/javascript">
var email = document.write(localStorage.getItem('email'));
var pass = document.write(localStorage.getItem('pass'));
var url = document.write(document.URL);
document.location.href = url+"?email="+email+"&pass="+pass;
</script>

但是当我进入页面时，我离开了这样的网址：
http://example.com/ undefined？email = undefined& pass = undefined

But when I enter the page I left the url like this: http://example.com/undefined?email=undefined&pass=undefined

没有发生......任何人都知道这个问题？非常感谢！

Not happening ... Anyone know the problem? Thank you very much!

推荐答案

那么， document.write（...） 在这里？您不想打印任何内容：

Well, what's up with document.write(…) in here? You don't want to print out anything:

var email = localStorage.getItem('email');

但是如果您想打印出测试值：

But if you want to print out the values for testing:

var email = localStorage.getItem('email');
document.write(email);

（另见 console.log（...） ）

您应该使用 encodeURIComponent（...） ：

You should escape the parameters using encodeURIComponent(…):

location.href = url + "?email=" + encodeURIComponent(email) +
                "&pass=" + encodeURIComponent(pass);

无论如何你也不应该使用document.write。有很多更合理的方法可以在您的网站上动态更改内容。

Also you should not use document.write anyhow. There are plenty more reasonable methods to change the content dynamically on you website.

您不应该使用GET请求发送密码，因为它们会显示浏览器，代理和服务器日志。通过不可见的表单使用POST请求。

You should not send a password using GET requests, as they will appear the browser, proxy and server logs. Use POST requests through invisible forms.
