HIDDEN Values <==Java Script Function Return value

Hi

Can you please go through the HTML files and let me know where am I going wrong?

Page1.html :

<html> <head> <title>PAGE 1</title> </head> <body> <form action="page2.html" method="get" name="LoginForm" id="LoginForm"> Username : <input name="username" size="20"> Password :<input name="password" type=password size="20"> <input type="submit" name="Login" value="Login" > <input type="reset" name="Reset2" value="Reset"> </form> </body> </html>

Page2.html : <html> <head> <title> Page2.html </title> <script type="text/javascript"> function GetParam(rname) { var rstart=location.search.indexOf("?"+rname+"="); if (rstart<0) rstart=location.search.indexOf("&"+rname+"="); if (rstart<0) return ' '; rstart += rname.length+2; var end=location.search.indexOf("&",rstart)-1; if (end<0) { end=location.search.length; } var result=''; for(var i=rstart;i<=end;i++) { var c=location.search.charAt(i); result=result+(c=='+'?' ':c); } return unescape(result); } </script> <body> <form name="page2" method=get action="page3.html"> <input type="hidden" name="uname" value=GetParam(username)> <input type="button" name="button" value="click"> </form> </body> </html>

When I tried to invoke GetParam(Username) javascript function, it didnt get the hidden element "UNAME" value instead it returned "GetParam(username)" itself.Can you put your ideas into this?

In Page3.html, I should be able to get the Hidden Values and Name for INPUT "UNAME".Is there any concept available??

Regards,
Parani.:rolleyes:

you're not calling the function, you're writing the function name. calling the function is only possible from a

sorry, my mistake, that first example should be:

<body onload="document.forms[0].elements['uname'].value = GetParam(username);">
...same as before...
</body>

Hi
I know I am late, but can be helpful for people seeking response for this kind of questions :) Here is one of the possible solution:
In your existing function

function GetParam(rname) {
..
..
//before returning
var unameElement = document.getElementById('unameid');
if (unameElement == null) {
 var udiv = document.getElementById('unamediv');
 var element1= document.createElement('INPUT');
 element1.type="hidden";
 element1.setAttribute('id','unameid');
 element1.setAttribute('name','uname');
 element1.setAttribute('value',uname);
 udiv.appendChild(ele1);
}else {
 unameElement.setAttribute('value',uname);
}
..
//may be now you do not need return stmt
}
</script>

<body>
<form name="page2" method=get action="page3.html">
<div id="unamediv"></div>
..
</form>
</body>
</html>
