The Behaviors API 319

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.

Arguments

applyBehaviorString

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

function inspectBehavior(enteredStr){

if(enteredStr){

//do your work here

}

Returns

Dreamweaver expects nothing.

Example

The following instance of the inspectBehavior() function, taken from the Display Status

Message.htm file, fills in the Message field in the Parameters dialog box with the message that

the user selected when the behavior was originally applied:

function inspectBehavior(msgStr){

var startStr = msgStr.indexOf("'") + 1;

var endStr = msgStr.lastIndexOf("'");

if (startStr > 0 && endStr > startStr) {

document.theForm.message.value = ¬

unescQuotes(msgStr.substring(startStr,endStr));

}

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.

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:

1 2 ... 314 315 316 317 318 319 320 321 322 323 324 ... 503 504
