EXTENDING DREAMWEAVER CS4

Commands

Otherwise, canAcceptCommand() returns the value false and Dreamweaver dims the item, as shown in the following

figure:

Link 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.

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()");

}

3 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.

Let 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.

1 Open the file Change Case.js.

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

1 2 ... 136 137 138 139 140 141 142 143 144 145 146 ... 386 387
