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:
<SCRIPT LANGUAGE="JavaScript"></SCRIPT>
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.
Note: Quotation marks ("")within the returned string must be preceded by a backslash (\) escape
character to avoid errors that the JavaScript interpreter reports.
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";
}
