Javascript 尝试获取URL参数，并将其与表单一起发布

我正在尝试获取一个登录页抓取URL参数。我在表单中有两个与参数名匹配的隐藏字段，但我似乎无法使其正常工作

注意：这个答案使用jQuery，在这种情况下，jQuery可能是浏览器兼容性的最佳选择，但如果您需要，我可以发布一个纯JS解决方案。

您的代码可以正常工作。您只需添加填充表单字段的部分：

 <input type="text" name="phone" placeholder="Phone Number" required="required">
 <select value="State" name="state" style="width:100%;height: 35px!important; margin-top: 10px!important;">
             <option value="">Please Choose a State:</option>

你反对使用jQuery吗？刚刚意识到你希望用JS来实现这一点。这将与PHP一起工作。感谢您的回复。我怎样才能让它只与JS一起工作？我已经设置了jQuery，并将它粘贴到页面上，但它仍然不起作用..嗯..刚刚修复了一个拼写错误，再试一次。我不知道我做的是否正确。你能很快看一下这页吗？我只是看了看——您已经将脚本放在jqueryinclude之上，将它移到下面，它应该可以工作了。如果没有，我再看一次。我做了另一个重要的改变，请再试一次。
