How to automate updating the value of a param for the selected outputs
Dear All;
I needs some advice from you to help me write a xslt for following tasks.
The problem is like this; say, there are 20 lines in the xml and 5 lines can be isplayed
for the given page number. The page number ,pageno, is defined using <xsl:param name="pageno" select="1"/>.
The output is done by calling a named template with the pageno named param.
I hope to be able to use prev and next link to automate updating the value of the pageno
and calling the named template for the sequential output.
I have tried some suggestions from the xsl-list archived records, and could not work out this specific task.
The xml and xsl is listed for your information. Any suggestion to the xslt will be much appreciated.
== xsl ==
<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
<xsl:output method="html" indent="yes" />
<xsl:param name="maxline" select="5"/>
<xsl:param name="pageno" select="2"/>
<xsl:template match="/">
<SCRIPT language="JScript"><xsl:comment>
<![CDATA[
var XSLTDOM;
function movenext()
{
XSLTDOM = new ActiveXObject('Msxml2.FreeThreadedDOMDocument');
// XSLTDOM = document.all['XSLDocument'];
XSLTDOM.async = false;
XSLTDOM.load('pageno.xsl');
var s = XSLTDOM.selectSingleNode("//xsl:param[@name ='pageno']/@select");
alert(s.value);
var str1;
str1 = parseInt(s.value) + 1;
alert(str1);
s.value=str1;
}
