将参数传递给xslt中的JavaScript脚本 [英] Passing parameters to javascript script in xslt

问题描述

是否可以在脚本位于标记< script type = text / javascript> ....< / script>之间的XSLT中处理JavaScript函数的参数。如果可能的话，有人可以举个例子。谢谢。

解决方案

我认为你在这两件事之间感到困惑：XSLT是用来产生HTML / JavaScript - 一旦生成HTML / JavaScript被浏览器接收，那么JavaScript就可以运行。我不知道任何这样的XSLT概念将一个变量传递给一个javascript函数。

我的猜测是你想要像这样的XSLT ...

p>

 < 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> 
  

如果您将javascript的主体body放在xsl：text元素中，这意味着您不会被保留字符（例如<>等）捕捉到。

设置到浏览器的生成的HTML / javascript最终会成为像这样，这意味着调用myFunc将显示hello world...

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

更新

<正如MichaelKey强调的那样，< xsl：text>以上元素是不必要的。这应该会产生同样的结果......

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

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.

解决方案

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>
