Copy failing when text is null

[Nothing4You]

Hey there,

suppose I have the following code:

<button id="copy-link" onclick="return false;">Copy link</button>

with

var clipboard;
var clipboardText = null;;
clipboard = new Clipboard('button#copy-link', {
    text: function() {
        return clipboardText;
    }
});
clipboard.on('success', function(e) {
    // success animation
});
clipboard.on('error', function(e) {
    // Custom error-catching prompt wrapper
    tryPrompt("You can copy the link with Control+C", clipboardText);
});

The content of clipboardText is dynamically set depending on what is currently needed.
Sometimes there is no link available, in which case I want to inform the user about that and run some other js stuff, prompting the user to provide a link.
However, due to the current check for text being set, when I return null it checks the same way as it would for undefined or even an empty string.
Is there currently any way to implement this feature?

just make it
return clipboardText || ' ';

As the comment in the other issue already tells, I'd rather not copy an empty string if there is null, since clearing the clipboard isn't what I'm looking for there.

Fixed at 7a5a910. Please use v1.5.10 in order to benefit from this.
