PRB: VBScript Style Event Trapping Does Not Work in JScript

ID: Q183617


The information in this article applies to:
  • Microsoft JScript, versions 2.0, 3.0


SYMPTOMS

In Microsoft JScript 1.0, the VBScript-style event syntax using Object_Event could be used to trap events. The following is an example of this syntax: function MyObject_MyEvent(a, b) { // event code }


CAUSE

JScript 1.0 incorrectly implemented the above syntax.


RESOLUTION

Use the FOR and EVENT attributes of the <SCRIPT> tag to handle JScript events.


STATUS

This behavior is by design.


MORE INFORMATION

The Object_Event syntax worked in JScript 1.0, but this incorrect syntax was removed in JScript 2.0.

Here is the correct syntax to trap events in JScript, using the FOR and EVENT attributes of the <SCRIPT> tag:


<SCRIPT LANGUAGE="JScript" FOR="MyObject" EVENT="MyEvent(a, b)">
   <!--
   // event code
   //--&gt;
</SCRIPT>
