Syntax

Parameters
vCode

iMilliSeconds
Required. Integer that specifies the number of milliseconds.
sLanguage
Optional. String that specifies one of the following values:
JScript

VBScript

Remarks
In versions earlier than Microsoft® Internet Explorer 5, the first argument of setTimeout must be a string. Evaluation of the string is deferred until the specified interval elapses.
As of Internet Explorer 5, the first argument of setTimeout can be a string or a function pointer.
The specified expression or function is evaluated once. For repeated evaluation, use the setInterval method.
When you use the setTimeout method with Introduction to DHTML Behaviors, the value of vCode should be a function pointer to call a function within the HTML Component (HTC) file or a string to call a function in the primary document.
