有没有办法改变网址是iframe？

Question

I want to show a page of my website within iframe in another page. I mean you can see helper.html while you are navigation main.php. but I want to change some links in helper.html regarding to some conditions set in main.php.

The regular solution is to get content of helper.html and process it in main.php, then echo it. But it is server side, I want this process to be client side.

Is that possible with JavaScript?

If those files are on different domains but you have a full control of them, then use the following solution:

• In the main page call an iframe with GET parameters. For instance:

  <iframe src="foo.html?parameter=value" width="400" height="500"></iframe>
  

• In an iframe parse GET parameters using Javascript and show an appropriate content:

  // get the current URL
  var url = window.location.toString();
  //get the parameters
  url.match(/\?(.+)$/);
  var params = RegExp.$1;
  // split up the query string and store in an
  // associative array
  var params = params.split("&");
  var queryStringList = {};
  
  for(var i=0;i<params.length;i++)
  {
      var tmp = params[i].split("=");
      queryStringList[tmp[0]] = unescape(tmp[1]);
  }
  
  // print all querystring in key value pairs
  for(var i in queryStringList)
      document.write(i+" = "+queryStringList[i]+"<br/>");
