=?Utf-8?Q?Call_a_function_defined_in_=E2=80=9Cmsxs?=

(Beginner's question)

Xml file contents:
<Results>
 <Iteration Sample="1" Pressure="14"
Derivative="0" Regression="0" />
<Iteration Sample="2" Pressure="16"
Derivative="0" Regression="0" />
<Iteration Sample="3" Pressure="10"
Derivative="0" Regression="0" />
<Iteration Sample="4" Pressure="25"
Derivative="0" Regression="0" />
</Results>
With XSLT file:
...
<xsl:template match="Iteration">
                <td onclick="user:onClickHandler( )">
<xsl:value-of select="@Sample" />
                </td>
                <td>
<xsl:value-of select=" @Dervative" />
                </td>
                <td onclick="clickIt()">
<xsl:value-of select="@Regression" />
                </td>
</xsl:template>
...
<msxsl:script language="JScript"
implements-prefix="user">
	function onClickHandler( )
        	{
        	}
</msxsl:script>

Please explain how I can call “onClickHandler” when user clicks somewhere 
inside “Sample” cell and pass sample number to this function (current 
implementation throws axception “Object required”)

Thank you,

Eugene

Thank you.

How can I pass a variable or a parameter to this function?

i. e.:

<xsl:param name="sampleParam" select="@Sample" />
...
   <td onclick="onClickHandler( $sampleParam );">
     ...
   </td>
   <script type="text/javascript">

   function onClickHandler (sampleParam ) {
     ...
   }
   </script>

Instead of <msxsl:script> use a normal <script> element; the former
is
only if you want to execute functions while the document is being trans-
formed.

That looks as if you want to use script in the HTML result document of 
the transformation. In that case forget about msxsl:script, simply do e.g.
   <td onclick="onClickHandler();">
     ...
   </td>
   <script type="text/javascript">
   function onClickHandler () {
     ...
   }
   </script>
that is simply insert a HTML script element in the transformation result.

You have to be aware that your XSLT stylesheet constructs a HTML 
document where in that case the HTML document has some script embedded. 
You can't pass parameters in the XSLT stylesheet to the script functions 
as the XSLT transformation is executed first and has as its result the 
HTML document with the script and the script is executed later. What you 
can do however is construct JavaScript code where you use values of XSLT 
parameters or values.
So you can use attribute value templates for instance to do e.g.
   <td onclick="onClickHandler({$sampleParam});">
but you need to make sure that you construct syntactically correct 
JavaScript code. Thus the above will work for instance if $sampleParam 
has a number value (e.g. 2.5) as that results in the JavaScript code
    onClickHandler(2.5);
If the $sampleParam is a string however then you need to make sure you 
construct a JavaScript string literal e.g.
   <td onclick="onClickHandler('{$sampleParam}');">
That will work as long as $sampleParam does not contain a single quote.
