Example

The following example determines which item, if any, should be checked in a pop-up menu of

paragraph formats and CSS styles.

function isCommandChecked()

{

var bChecked = false;

var style = arguments[0];

var textFormat = dw.getDocumentDOM().getTextFormat();

if (dw.getDocumentDOM() == null)

bChecked = false;

if (style == "(None)")

bChecked = (dw.cssStylePalette.getSelectedStyle() == ’’ || textFormat ==

"" || textFormat == "P" || textFormat == "PRE");

else if (style == "Heading 1")

bChecked = (textFormat == "h1");

else if (style == "Heading 2")

bChecked = (textFormat == "h2");

else if (style == "Heading 3")

bChecked = (textFormat == "h3");

else if (style == "Heading 4")

bChecked = (textFormat == "h4");

else if (style == "Heading 5")

bChecked = (textFormat == "h5");

else if (style == "Heading 6")

bChecked = (textFormat == "h6");

else

bChecked = (dw.cssStylePalette.getSelectedStyle() == style);

return bChecked;

}

isDOMRequired()

Description

The isDOMRequired() function specifies whether the toolbar command requires a valid DOM

to operate. If this function returns

true or if the function is not defined, Dreamweaver assumes

that the command requires a valid DOM and synchronizes the Code view and Design view for

the document before executing the associated command. This function is equivalent to the

domRequired attribute in a toolbar item tag.

Arguments

None.

Returns

Dreamweaver expects true if the DOM is required; false if the DOM is not required.

Example

function isDOMRequired()

{

return false;

}
