behaviorFunction()

Description

This function inserts one or more functions—surrounded by the following tags, if they don’t

yet exist—into the

HEAD section of the user’s document:

Arguments

None.

Returns

Dreamweaver expects either a string that contains the JavaScript functions or a string that

contains the names of the functions to be inserted in the user’s document. This value must be

exactly the same every time (it cannot depend on user input). The functions are inserted only

once, regardless of how many times the action is applied to elements in the document.

Example

The following instance of the behaviorFunction() function returns the MM_popupMsg()

function:

function behaviorFunction(){

return ""+

"function MM_popupMsg(theMsg) { //v1.0\n"+

" alert(theMsg);\n"+

"}";

}

The following example is equivalent to the preceding behaviorFunction() declaration and

is the method used to declare the

behaviorFunction() function in all behaviors that come

with Dreamweaver:

function MM_popupMsg(theMsg){ //v1.0

alert(theMsg);

}

function behaviorFunction(){

return "MM_popupMsg";

}

NOTE

Quotation marks ("")within the returned string must be preceded by a backslash (\)

escape character to avoid errors that the JavaScript interpreter reports.
