Use JS to get parameters in HTML Web pages.

Use JS to get parameters in HTML Web pages.
We know that HTML pages are executed on the client side, so that the parameters must be obtained using client script (such as JavaScript), which differs from the server-side script fetching parameters.
The following JS code to get HTML page shape such as "Test.html?foo=mytest&program=flash" "?" After all the parameters.

<script language=javascript>
<!--
var hrefstr,pos,parastr;
Hrefstr = window.location.href;
pos = Hrefstr.indexof ("?");
Parastr = hrefstr.substring (pos+1);
if (pos>0) {
document.write ("All Parameters:" +PARASTR);
} else {
document.write ("no parameters");
}
-->
</script>

The following JS code can be more detailed to get an HTML page of a parameter

<script language=javascript>
<!--
function Getparastr (strname) {
var hrefstr,pos,parastr,para,tempstr;
Hrefstr = window.location.href;
pos = Hrefstr.indexof ("?")
Parastr = hrefstr.substring (pos+1);

Para = Parastr.split ("&");
Tempstr= "";
for (i=0;i<para.length;i++)
{
  TempStr = Para[i];
  pos = tempstr.indexof ("=");
  if (tempstr.substring (0,pos) = = strname) {
   Return tempstr.substring (pos+1);
  }
}
return null;
}
Get program Parameters
var programstr = getparastr ("program");
document.write (PROGRAMSTR);
-->
</script>
