152 Insert Bar Objects

Next, decide whether to use objectTag() or insertObject() for the next function. The

Strikethrough object simply wraps the

s tag around the selected text, so it doesn’t meet the

criteria for using the

insertObject() function (see “insertObject()” on page 162).

Within the

objectTag() function, use dw.getFocus() to determine whether the Code view

is the current view. If the Code view has input focus, the function should wrap the

appropriate (uppercase or lowercase) tag around the selected text. If the Design view has input

focus, the function can use

dom.applyCharacterMarkup() to assign the formatting to the

selected text. Remember that this function works only for supported tags (see

dom.applyCharacterMarkup() in the Dreamweaver API Reference). For other tags or

operations, you may need to use other API functions. After Dreamweaver applies the

formatting, it should return the insertion point (cursor) to the document without any

messages or prompting. The following procedure shows how the

objectTag() function

now reads.

To add the objectTag() function:

1. In the HEAD section of the Strikethrough.htm file, after the isDOMRequired() function,

add the following function:

function objectTag() {

// Determine if the user is in Code view.

var dom = dw.getDocumentDOM();

if (dw.getFocus() == 'textView' || dw.getFocus(true) == 'html'){

var upCaseTag = (dw.getPreferenceString("Source Format", "Tags Upper

Case", "") == 'TRUE');

// Manually wrap tags around selection.

if (upCaseTag){

dom.source.wrapSelection('<S>','</S>');

}else{

dom.source.wrapSelection('<s>','</s>');

}

// If the user is not in Code view, apply the formatting in Design

view.

}else if (dw.getFocus() == 'document'){

dom.applyCharacterMarkup("s");

}

// Just return--don't do anything else.

return;

}

Save the file as Strikethrough.htm in the Configuration/Objects/Text folder.

Instead of including the JavaScript functions in the

HEAD section of the HTML file, you can

create a separate JavaScript file. This separate organization is useful for objects that contain

several functions, or functions that might be shared by other objects.
