Question

我有一个jsp页面，它打开一个html页面并传递一些隐藏的参数。如下......

<form name="DMSForm" method="post" action="<bean:write name="URL"/>" >
<input type="hidden" name="userName" value="<bean:write name="userName"/>">
<input type="hidden" name="password" value="<bean:write name="password"/>">

HTML页面有很多其他代码，除了它调用一个url，它需要发送从JSP接收的这些userName和密码。如下......

<frame longdesc="/styles/blank.htm" name="topFrame" id="topFrame" src="**/servlets/servlets.CH_Vault?INT=1&amp;Name=UserNameFromJSP;&amp;Password=passwordFromJSP;**" border="0" frameborder="no" noresize scrolling="no"/>

如何在html中访问JSP传递的userName和密码？

不幸的是，HTML和JavaScript无法处理给定的URL参数。

你可以用一点JavaScript来做到这一点

function gup( name, url ) {
  // If you don't specify an URL in the parameters, it will take the current URL of the browser
  if (!url) url = location.href;
  name = name.replace(/[\[]/,"\\\[").replace(/[\]]/,"\\\]");
  var regexS = "[\\?&]"+name+"=([^&#]*)";
  var regex = new RegExp( regexS );
  var results = regex.exec( url );
  return results == null ? null : results[1];
}

var testUrl = "www.test.com/t.html?a=1&b=3&promo=m2-m3-m4-m5"
var promo_param = gup('promo', 'test') // returns "m2-m3-m4-m5"

如何访问从JSP传递的参数作为HTML页面的隐藏输入？
