AJAX - Sarissa - updateContentFromURI()

firemankurt

I am trying to simplify the AJAX content in my scripts and started looking into "Sarissa" to help with this.

I am trying to understand how to use updateContentFromURI() and am just not getting any where.

Here is a simple example where all I am trying to do is insert the content of the XML file into the div with id "response".

Obviously it is not working or I would not be posting here. Anyone had success with Sarissa? Any simple examples or suggestions for making this work?

My PHP/HML doc:

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml" xml:lang="en" lang="en"><head>
  <meta name="GENERATOR" content="Quanta Plus">
  <meta http-equiv="Content-Type" content="text/html; charset=iso-8859-1">
<script type="text/javascript" src="../../sarissa.js"> </script>
<script type="text/javascript" src="../../sarissa_dhtml.js"> </script>  

<script type="text/javascript">
respdiv = document.getElementById("response");
Sarissa.updateContentFromURI("resp.xml",respdiv);
</script> 

</head>
<body>
	<div id="response">
	</div>

<div id="content">
	<p>More stuff.</p> 
</div>
</body>
</html>

My XML doc:

<?xml version="1.0" encoding="UTF-8" standalone="yes"?>
<!DOCTYPE response [
	  <!ELEMENT response (method,result)>
	  <!ELEMENT method      (#PCDATA)>
	  <!ELEMENT result    (#PCDATA)>
]>
<response>
  <method>checkName</method>
  <result>1</result>
</response>

Sarissa scripts are installed "../../" relative to both these files.

When I load the page Firefox Error Console shows:

Error: oNode has no properties
Source File: http://localhost/~kurt/sarissa/sarissa.js
Line: 533

Thanks in advance.

OK... I am finally getting somewhere

My PHP or HTML file:

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml" xml:lang="en" lang="en"><head>
  <meta name="GENERATOR" content="Quanta Plus">
  <meta http-equiv="Content-Type" content="text/html; charset=iso-8859-1">
<script type="text/javascript" src="../../sarissa.js"> </script>
<script type="text/javascript" src="../../sarissa_dhtml.js"> </script>  

<script type="text/javascript">
// script must be in a function and called later so that all elements are loaded and recognized
function DoItNow(){
respdiv = document.getElementById("response");
Sarissa.updateContentFromURI("response.php",respdiv);
}
</script>

</head>
<body onload="DoItNow();">
    <div id="response">
    </div>

<div id="content">
    <p>More stuff.</p>
</div>
</body>
</html>

My PHP/XML file being called by the page above:

<?php
// modifying header is required to get browser to recognize returned file as XML
header('Content-type: text/xml'); 
echo '<response>
  <method>checkName</method>
  <result>1</result>
</response>';
?>

Still much to learn but much simpler than other AJAX methods.
