分享急求msxsl:script元素的使用方法和例子
使用微软的xslt元素msxsl:script时老是出现错误，本人编写的程序：
<msxsl:script language="javascript" implements-prefix="urn:schemas-microsoft-com:xslt">window.alert('natify');</msxsl:script>
但该程序无法在msxml2.xsltemplate对象中执行转换，请高手指教！！
<msxsl:script language="javascript" implements-prefix="urn:schemas-microsoft-com:xslt">window.alert('natify');</msxsl:script>

TestSample.xsl改成
……
<xsl:for-each select="data/value">
<xsl:if test="position()=last()">
setVariable(<xsl:value-of select="@id"/>);
</xsl:if>
</xsl:for-each>
……
TransformFile.htm改成
……
function initialFun() {
……
pro.transform();
window.execScript(pro.output);
}
……
……
<xsl:for-each select="data/value">
<xsl:if test="position()=last()">
setVariable(<xsl:value-of select="@id"/>);
</xsl:if>

隐藏文本框的id也是可以通过xsl生成

try
<xsl:if test="position()=last()">
<script language="javascript" defer="true">setVariable(<xsl:value-of select="@id"/>);</script>
</xsl:if>
there seems to be a bug, you need to output some text , or try
<xsl:if test="position()=last()">
<xsl:element name="script">
<xsl:attribute name="language">javascript</xsl:attribute>
<xsl:attribute name="defer">true</xsl:attribute>
setVariable(<xsl:value-of select="@id"/>);

why do you need an event handler? you can just call the method

Yes, saucer(思归/MVP).But the page that I use xsl transform is a no refreshing page,so it is difficult to reload the window.onload event handle.I do all data exchange by xmlhttp,and I do not need to refresh the page.
Can you get a solution that execute the event handler automatically?

bdhh(Silent),您提供的方法并不十分可行。
因为，每个隐藏文本框都带唯一id,当我们要获取其中的值时必须要知道明确的文本框id，但xsl无法捕获这些id，如果xsl能记录这些id的话，我们也就无需再用隐藏文本框了，我们可以直接保存值到记录变量中，所以这种方法不十分可行。

if I understand you correctly, write a window.onload event handler

Oh,Yes!Thanks for saucer(思归/MVP)'s great help!
I think your sample code has illuminate everything that puzzle me some days.Thank you very much again.
By the way,may I ask you another question? Your sample code has soled the transform and evaluate problem indeed, but the javascript function still depend on the element event,and the evaluate statement only execute by custom event.So how can I make it executing immediately all javascript code of the transformer itself ?

xsl是用来讲一个xml转换成另外一个xml的。所以它无法与目标文档交互是正常的,它根本不会识别dom。
另外,浏览器的解析过程是将xml转换成xhtml然后才生成dom,也就是说转换过程中dom还没有形成。
而且它没有界面交互能力，所以不能调用alert。

you'd better create a simple xml/xsl sample, tell us exactly what you want
<script language="javascript">
val = "<xsl:value-of select='....' />";
</script>
<script language="javascript">
val = "<xsl:value-of select='....' />";
</script>

谢谢bdhh(Silent),您所提到的问题很有道理。
本人想解决的是一个传值的问题：用xsl转换xml后怎样将原来xml中特定的数据写入生成的HTML文件页里的javascript变量中？
若我只用一个xsl模板，每次更换xml，并保持对xml进行转换操作的javascript脚本不刷新，则怎样转换特定的xml数据到javascript变量中，而不是直接转换成静态HTML？

Thanks for saucer(思归/MVP),and thanks for your commendatory site.I think you are right.The value saved in the global variable may be evaluated again or lost its original value.
But,what I want to resolve is that how can I get a value from the xsl transforming process,why I refer to the <msxsl:script> element is I want to use the javascript in xsl to interact with the javascript in HTML.I need a dynamic data exchange.Now the xsltemplate only give me the <xsl:param> to input values,but it can not give me a way to output values as dynamically interact usage,which just like a javascript variable.
