Selected Text for Command UI Window

[jgiotta]

I'm creating my first Dreamweaver Custom Command. I want to use the selected
text in the document for JavaScript to wrap into a custom tag. However, I want
the Command UI input to value the selected text. Basically, if no text is
selected it just simply inserts the text entered from the input field, but if
there is text selected then I don't the input field to be empty.

To get the user's selection you can use the following code:
var dom = dw.getDocumentDOM()
var sel = dom.getSelection();
var html = dom.documentElement.outerHTML;

// see what the selection is
// can use this to set the value of your text field.
alert(html.substring(sel[0],sel[1]));


But you can test the offsets within sel to see if there is anything
selected. If sel[0] and sel[1] are equal then there is nothing selected,
there is only an insertion point.

I figured out a solution. In the HTML document for the UI, I added a onLoad
event to the body tag. It grabs the selected text and populates the input
field. Example:

function myValue(input) {
var theDOM = dw.getDocumentDOM();
var theDocEl = theDOM.documentElement;
var theWholeDoc = theDocEl.outerHTML;
var theSelNode = theDOM.getSelectedNode();
var theSel = theDOM.getSelection();
var selText = theWholeDoc.substring(theSel[0],theSel[1]);
input.value = selText;
}
