A simple command example 173

Linking functions to the OK and Cancel buttons

When the user clicks OK or Cancel, the extension needs to perform the appropriate action.

You determine the appropriate action by specifying which JavaScript function to perform

when either button is clicked.

To link the OK and Cancel button to functions:

1. Open the file Change Case.js in the Configuration/Commands folder.

2. At the end of the file, add the following code:

function commandButtons() {

return new Array("OK", "changeCase()", "Cancel", "window.close()");

}

Save the file.

The

commandButtons() function causes Dreamweaver to supply the OK and Cancel buttons

and tells Dreamweaver what to do when the user clicks them. The

commandButtons()

function tells Dreamweaver to call

changeCase() when the user clicks OK and to call

window.close() when the user clicks Cancel.

Letting the user specify uppercase or lowercase

When the user clicks a menu item, the extension needs a mechanism to let the user select

uppercase or lowercase. The UI provides this mechanism by defining two radio buttons to let

the user make that choice.

To let the user specify uppercase or lowercase:

1. Open the file Change Case.js.

2. At the end of the file, add the following code:

function changeCase() {

var uorl;

// Check whether user requested uppercase or lowercase.

if (document.forms[0].elements[0].checked)

uorl = 'u';

else

uorl = 'l';

// Get the DOM.

var theDOM = dw.getDocumentDOM();

// Get the outerHTML of the HTML tag (the

// entire contents of the document).

var theDocEl = theDOM.documentElement;

var theWholeDoc = theDocEl.outerHTML;
