I see the same behavior in my instantiation of that code as well.

$.prompt($(this).clone(withDataAndEvents).html(), options);

should look like this:

$.prompt($(this).clone(options.withDataAndEvents).html(), options);

-> between lines 204 and 205:
if (clicked.constructor == Array) {
clicked = clicked[0];
}

For my own needs, I added something which may be useful for others: have an optional title attribute associated to some prompt buttons.

To achieve it, I simply inserted the followings (line numbers below refer to 3.0 development version):
-> between lines 65 and 66:
var title=”;
if (v.constructor == Array) {
title = v[1];
v = v[0];
}
-> inside line 66, where the end of the line becomes:
…v + ‘”‘+ (title?(‘ title=”‘+title+’”‘):”) +’>’ + k + ”;

With this patch, using jqImpromptu may look like:
$.prompt (‘Some text’, buttons: {Ok: [true, 'Will save your changes'], Cancel: false});

This manner, the option is that each button value may be, either:
- a simple response value
- an array [response value, title string]
It might be extended to a more sophisticated version, where an object should also be accepted in place of the array, containing attr/value pairs.

Hope this helps.

Thanks a lot for your work!
