Javascript in XSLT namespace error

Here is my XSLT...

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE xsl:stylesheet [ <!ENTITY nbsp " "> ]>
<xsl:stylesheet
version="1.0"
xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
xmlns:msxml="urn:schemas-microsoft-com:xslt"
xmlns:msxsl="urn:schemas-microsoft-com:xslt"
xmlns:myjs="myjs"
xmlns:umbraco.library="urn:umbraco.library"
xmlns:Exslt.ExsltCommon="urn:Exslt.ExsltCommon"
xmlns:Exslt.ExsltDatesAndTimes="urn:Exslt.ExsltDatesAndTimes" xmlns:Exslt.ExsltMath="urn:Exslt.ExsltMath" xmlns:Exslt.ExsltRegularExpressions="urn:Exslt.ExsltRegularExpressions" xmlns:Exslt.ExsltStrings="urn:Exslt.ExsltStrings" xmlns:Exslt.ExsltSets="urn:Exslt.ExsltSets" xmlns:tagsLib="urn:tagsLib" xmlns:BlogLibrary="urn:BlogLibrary" xmlns:pdcalendar="urn:pdcalendar" xmlns:PS.XSLTsearch="urn:PS.XSLTsearch"
exclude-result-prefixes="msxsl myjs msxml umbraco.library Exslt.ExsltCommon Exslt.ExsltDatesAndTimes Exslt.ExsltMath Exslt.ExsltRegularExpressions Exslt.ExsltStrings Exslt.ExsltSets tagsLib BlogLibrary pdcalendar PS.XSLTsearch ">

<xsl:output method="xml" omit-xml-declaration="yes"/>

<xsl:param name="currentPage"/>

<xsl:template match="/">
<msxsl:script language="JavaScript" implements-prefix="myjs">
<![CDATA[
function jumpToPage(){
// stuff goes here
}
]]>
</msxsl:script>


<select>
<xsl:attribute name="onChange">
<xsl:value-of select="myjs:jumpToPage(this.selectedValue)"/>
</xsl:attribute>

<xsl:for-each select="$currentPage/*">
<option>
<xsl:attribute name="value">
<xsl:value-of select="@urlName"/>
</xsl:attribute>
<xsl:value-of select="@nodeName"/>
</option>
</xsl:for-each>
</select>

</xsl:template>

</xsl:stylesheet>

I get this error:

System.Xml.Xsl.XslTransformException: Cannot find a script or an extension object associated with namespace 'myjs'.
at System.Xml.Xsl.Runtime.XmlQueryContext.InvokeXsltLateBoundFunction(String name, String namespaceUri, IList`1[] args)

at umbraco.presentation.webservices.codeEditorSave.SaveXslt(String fileName, String oldName, String fileContents, Boolean ignoreDebugging)
What am I missing?

Thanks in advance!

Hi James,

This is JavaScript you want to be able to execute in the browser (client-side), right?

The <msxsl:script> element is used for scripting stuff the XSLT can't do very well (like Regular Expression, Date calculations etc.).

You can just do something like this:
```
<script type="text/javascript"> 
<![CDATA[
function jumpToPage() {
    // stuff goes here
}
]]>
</script>
...
<select onchange="jumpToPage(this.selectedValue)">
    <xsl:for-each select="$currentPage/*">
        <option value="{@urlName}">
            <xsl:value-of select="@nodeName" />
        </option>  
    </xsl:for-each>
</select> 
```
