Answer 1

我会使用myval，因为val是一个返回整数的函数。

你有没有尝试过：

<cfoutput>
   <script type="text/javascript">
       alert("#myval#");
   </script>
</cfoutput>

Answer 2

如果您想将CF值转换为Javascript值，请使用ToScript。

<cfset thisString="hello world">
<script type="text/javascript" language="JavaScript">
<cfoutput>
var #toScript(thisString, "jsVar")#;
</cfoutput>
</script>
