Access VBScript variable within Javascript inside of an HTA

问题

I'm trying to access a variable in javascript that i set in vbscript all within one hta file:

<script type="vbscript">
    var globalVariable = test123
</script>

<script type="text/javascript">
    var globalVariable = <%= globalVariable %>;
</script>

This doesn't populate the variable globalVariable with anything. I've also tried

var globalVariable = "<%= globalVariable %>";

This just populates the string within the quotes into the variable globalVariable.

I can't get the value 'test123' set in the VBScript section to populate into a JS variable within the JS section.

Any help would be appreciated.

Based on your question, I've written an HTA containing the following code:

<script type="text/vbscript">
dim globalvariable
globalvariable = "test123"
</script>
<script type="text/javascript">
alert(globalvariable);
</script>

and the value "test123" is displayed in the alert box.

Note the following differences with your code:

vbs language syntax is different to js syntax;
your js code looks like asp code to me, rather than js;
I got an error message using '' without 'text/' prefix;

Mixing languages in a .HTA App is easy, if you just follow the syntactical rules for each language (e.g. there is no "var" in VBScript).

<html>
 <head>
  <hta:application id = "mix"></hta>
  <script LANGUAGE="VBScript">
  Dim gsX : gsX = "global VBScript variable"
  </script>
  <script LANGUAGE="JScript">
  alert(gsX);
  </script>
 </head>
 <body>
 </body>
</html>

Can you use a DOM element like a hidden input field to communicate between VBScript and JS? If that works you can trigger a custom event when the value changes, and listen for that event on both sections.

I never used VBScript before so this may not be possible.
