objectTag()

Description

The objectTag() and insertObject() functions are mutually exclusive: If both are defined

in a document, the

objectTag() function is used. For more information, see “insertObject()”

on page 162.

This function inserts a string of code into the user’s document. In Dreamweaver MX,

returning an empty string, or a

null value (also known as "return;"), is a signal to

Dreamweaver to do nothing.

In Dreamweaver 4, if the focus is in Code view and the selection is a range (meaning that it is

not an insertion point), the range is replaced by the string that the

objectTag() function

returns. This is the value

true, even if the objectTag() function returns an empty string or

returns nothing. The

objectTag() function returns an empty string or a null value because

edits to the document have already been made manually. Otherwise, double quotation marks

(" ") often delete the edit by replacing the selection.

Arguments

None.

Returns

Dreamweaver expects the string to insert into the user’s document.

Example

The following example of the objectTag() function inserts an OBJECT/EMBED combination

for a specific ActiveX control and plug-in:

function objectTag() {

return '\n' +

'<OBJECT CLASSID="clsid:166F1OOB-3A9R-11FB-8075444553540000" \n'¬

+ 'CODEBASE="http://www.mysite.com/product/cabs/¬

myproduct.cab#version=1,0,0,0" \n' + 'NAME="MyProductName"> \n' ¬

+ '<PARAM NAME="SRC" VALUE=""> \n' + '<EMBED SRC="" HEIGHT="" ¬

WIDTH="" NAME="MyProductName"> \n' + '</OBJECT>'

}

NOTE

The assumption is that edits have been made manually before the return statement, so

doing nothing in this case is not equivalent to clicking Cancel.
