Passing parameters to javascript script in xslt

Question

Is it possible to handle a parameter to a javascript function in XSLT where the script is between tags <script type=text/javascript>....</script>. If possible could someone give a example. Thanks.

I think you're getting confused between the two things: XSLT is something that is used (in this case) to generate HTML/javascript - once that generated HTML/javascript is received by the browser then the javascript can be run. I'm unaware of any such concept of the XSLT "passing" a variable to a javascript function.

My guess is you want something like this XSLT...

<script type="text/javascript">
  var myVar = "<xsl:value-of select="XPATHVALUE"/>";
  <xsl:text disable-output-escaping="yes"><![CDATA[
    function myFunc(){
      alert(myVar);
    }
  ]]></xsl:text>
</script>

If you put the main "body" of the javascript within the xsl:text element, it means you won't get caught out using reserved characters (such as < > etc).

The generated HTML/javascript that is set to the browser would end up as something like this, meaning calling myFunc would display "hello world"...

<script type="text/javascript">
  var myVar = "hello world";
    function myFunc(){
      alert(myVar);
    }
</script>

Update

As MichaelKey has highlighted, the <xsl:text> element above is unnecessary. This should produce the same thing...

<script type="text/javascript">
  var myVar = "<xsl:value-of select="XPATHVALUE"/>";
  <![CDATA[
    function myFunc(){
      alert(myVar);
    }
  ]]>
</script>
