Description
System message and event handler; in a movie with Macromedia Shockwave content, contains
statements that run when the handler receives an
EvalScript message from a browser. The
parameter is a string passed in from the browser.
• The EvalScript message can include a string that Director can interpret as a Lingo statement.
Lingo cannot accept nested strings. If the handler you are calling expects a string as a
parameter, pass the parameter as a symbol.
• The on EvalScript handler is called by the EvalScript() scripting method from JavaScript
or VBScript in a browser.
Include only those behaviors in
on EvalScript that you want users to control; for security
reasons, don’t give complete access to behaviors.
Note: If you place a return at the end of your EvalScript handler, the value returned can be used by
JavaScript in the browser.
