Venkat PSubject: accessing Javascript variable in XSL
Author: Venkat P
Date: 12 Jun 2008 09:05 AM
Hi,

I have a requirement in which I have to compare the XSL node attribute value with a variable which is a parameter to java script function.

Please observe the following code snippet:



<script language="javascript">

function showPopUp(id){
id);
document.write('<xsl:for-each select="level1/level2/level3/level4[@id=(here I need the value of the parameter id)]/level5"><xsl:value-of select="name"/></xsl:for-each>');
}
</script>

<xsl:for-each select="level1/level2/level3/level4">
<ul class="compact">
<li><span><a href="javascript:showPopUp('{@id}')"><strong><xsl:value-of select="begin"/><xsl:text> - </xsl:text><xsl:value-of select="end"/></strong></a></span></li>
</ul>
</xsl:for-each>



In this code I am calling the java script function from XSL with the attribute value as the parameter. I am able to call the function with the exact parameter. But I am unable to access the javascript parameter value to use in XSL for comparision.

Please help me.

Thank you.

Hi,
you cannot evaluate an XSLT instruction in order to build the body of a function that will receive an argument dynamically (after the XSLT finishes writing it). The only option is to run the for-each on 'level5' inside the 'level4' loop, gather the 'name' values into an array and pass that array to showPopUp.

Hope this helps,
Alberto
