javascript - Safari 5.1 prompt() function and cancel

Question

In most browsers (including older versions of Safari), the Javascript prompt function returns null when the user clicks "Cancel", and the empty string if the user clicks "Ok" with nothing in the text box. But in Safari 5.1, it returns the empty string for both cases.

I used Safari's "report a bug" feature to report it to Apple, but who knows when they might even acknowledge it much less fix it. Does anyone have a workaround?

Answer 1

var res = prompt('hello?', '')
if (res === null || res === '' && isSafari && confirm('was that cancel?'))
    cancel
