The ID must be a unique name for the button (following standard naming conventions, use DW_Text_Strikethrough for this object). The image and file attributes simply tell Dreamweaver the location of the supporting files, as shown here: 3 Save the insertbar.xml file. 4 Reload the extensions (see "Reloading extensions" on page 74). The new object appears at the beginning of the Common category on the Insert bar, as shown in the following figure: Adding a dialog box You can add a form to your object to let the user enter parameters before Dreamweaver inserts the specified code (for example, the Hyperlink object requests the text, link, target, category index, title, and access key values from the user). In this example, you add a form to the Strikethrough object from the previous example. The form opens a dialog box that provides the user with the option to change the text color to red as well as add the strike-through tag. This example assumes you have already created a separate JavaScript file called Strikethrough.js. First, in Strikethrough.js, you add the function that the form calls if the user changes the text color. This function is similar to the objectTag() function for the Strikethrough object, but is an optional function. To create the function: 1 After the objectTag() function in Strikethrough.js, create a function called fontColorRed() by entering the following code: function fontColorRed(){ 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('',''); }else{ dom.source.wrapSelection('',''); } }else if (dw.getFocus() == 'document'){ dom.applyFontMarkup("color", "#FF0000"); } // Just return -- don't do anything else. return; }

This line identifies the beginning of the Common category on the Insert bar.
2
Start a new line after the category tag; then insert the
button
tag and assign it the
id
,
image
, and
file
attributes
for the Strikethrough object.
The ID must be a unique name for the button (following standard naming conventions, use
DW_Text_Strikethrough
for this object). The
image
and
file
attributes simply tell Dreamweaver the location of
the supporting files, as shown here:
<button id="DW
_
Text
_
Strikethrough"
image="Text\Strikethrough.gif"
file="Text\Strikethrough.htm"/>
3
Save the insertbar.xml file.

Reload the extensions (see “Reloading extensions” on page 74).
The new object appears at the beginning of the Common category on the Insert bar, as shown in the following figure:
Adding a dialog box
You can add a form to your object to let the user enter parameters before Dreamweaver inserts the specified code
(for example, the Hyperlink object requests the text, link, target, category index, title, and access key values from the
user). In this example, you add a form to the Strikethrough object from the previous example. The form opens a
dialog box that provides the user with the option to change the text color to red as well as add the strike-through tag.
This example assumes you have already created a separate JavaScript file called Strikethrough.js.
First, in Strikethrough.js, you add the function that the form calls if the user changes the text color. This function is
similar to the
objectTag()
function for the Strikethrough object, but is an optional function.
To create the function:
1
After the
objectTag()
function in Strikethrough.js, create a function called
fontColorRed()
by entering the
following code:
function fontColorRed(){
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('<FONT COLOR="#FF0000">','</FONT>');
}else{
dom.source.wrapSelection('<font color="#FF0000">','</font>');
}
}else if (dw.getFocus() == 'document'){
dom.applyFontMarkup("color", "#FF0000");
}
// Just return -- don't do anything else.
return;
}
