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:
Open the file Change Case.js.

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;
// Get the node that contains the selection.
var theSelNode = theDOM.getSelectedNode();
// Get the children of the selected node.
var theChildren = theSelNode.childNodes;
var i = 0;
if (theSelNode.hasChildNodes()){
while (i < theChildren.length){
if (theChildren[i].nodeType == Node.TEXT_NODE){
var selText = theChildren[i].data;
var theSel = theDOM.nodeToOffsets(theChildren[0]);
break;
}
++i;
}
}
else {
// Get the offsets of the selection
var theSel = theDOM.getSelection();
// Extract the selection
var selText = theWholeDoc.substring(theSel[0],theSel[1]);
