AJAX: Pass vale to Server from Javascript

forums.siva · 07-05-2010, 09:02 PM

Hello

I am using PlainAjax. http://coolpenguin.net/plainajax/?p=examplespostdata

Here is my code and it is not working if i called from Javascript function.

Code:

<script type="JavaScript" src="plainajax.js"></script>
<script language="JavaScript" >

function openWin()
{
	.......		
	.......
	.......
	var selval = selectedValue.toString();	 	// Dynamic value variable
	document.formlist.myval.value = selval; 	// stored to hidden variable

	
	 var cn = document.getElementById( "itsme" ).childNodes;	// Get all the nodes
	
	 var myresult = new Array();					// declare result array
    	 plainajax.request('respurl: req_php.php; resultloc: myresult; paramloc: cn;');
  
	 Window.open("req_php.php");
	
}

</script>

<html>

 <div id="itsme">

	<input type="hidden" name="myval" id="myval" value=""> 
</div>

</html>

req_php.php
=========

Code:

<?php

		echo "value from html = ".$_REQUEST['myval']."<br>";
	
?>

But i am not able to get any value in my php program. What i did wrong in this?

or is anyother way to pass the variable from Javascript (except pass thru url query string, this is not secure)

Thanks

Your input is a hidden input, which means the user can't alter it. Since that hidden input is an empty string, your PHP script is probably printing out the correct value--an empty string (which prints nothing on the screen).
