Arguments

For pop-up menus, combo boxes, text boxes, and color pickers, the first argument is the

current value within the control. The

getDynamicContent() function can optionally attach

individual IDs to items within a pop-up menu. If the selected item in the pop-up menu has

an ID attached, Dreamweaver passes that ID to the

receiveArguments() function instead of

the value. For combo boxes, if the current contents of the text box do not match an entry in

the pop-up menu, Dreamweaver passes the contents of the text box. To determine whether

the text box matches, Dreamweaver compares against the pop-up menu without case-

sensitivity.

If you specified the

arguments attribute, those arguments are passed next. If you did not

specify the

arguments attribute, Dreamweaver passes the ID of the item.

Returns

Dreamweaver expects nothing.

Example

function receiveArguments(newTitle)

{

var dom = dw.getDocumentDOM();

if (dom)

dom.setTitle(newTitle);

}

showIf()

Availability

Dreamweaver MX.

Description

Specifies that an item appears on the toolbar only if the function returns a true value. For

example, you can use the

showIf() function to show certain buttons only when the page has

a certain server model. If the

showif() function is not defined, the item always appears. The

showIf() function is the same as the showIf attribute in a toolbar item tag.

The

showIf() function is called whenever the item’s enabler runs; that is, according to the

value that the

getUpdateFrequency() function returns.

Arguments

None.
