// such as "show" or "hide") to the existing list of argument

inspectBehavior()

Description

This function inspects the function call for a previously applied behavior in the user’s document and sets the values of

the options in the Parameters dialog box accordingly. If the

inspectBehavior() function is not defined, the default

option values appear.

Note: The inspectBehavior() function must rely solely on information that the applyBehaviorString argument

passes to it. Do not attempt to obtain other information about the user’s document (for example, using

dreamweaver.getDocumentDOM()) within this function.

Arguments

applyBehaviorString

This argument is the string that the applyBehavior() function returns.

Note: If the HTML element contains code that is similar to 'onClick="someBehavior(); return

document.MM_returnValue;"', and you add a new behavior from the behavior menu, Dreamweaver calls

inspectBehavior() as soon as the new behavior UI pops up, and passes an empty string as the parameter.

Consequently, be sure to check the

applyBehaviorString parameter, as shown in the following example:

function inspectBehavior(enteredStr){

if(enteredStr){

//do your work here

}

Returns

Dreamweaver expects nothing.
