Copying empty text to clipboard throws javascript error.

[dweepcan]

I was trying to replace ZeroClipboard with this new clipboard.js library to get rid of the flash dependancy, but I felt this one workflow was unsupported with this library. An example of this is showcased here: https://jsfiddle.net/o6g9gu2w/. When trying to copy empty text, due to user input being empty, I get the following error: Missing required attributes, use either "target" or "text" caused by the following line

clipboard.js/src/clipboard-action.js

Line 45 in d925445

throw new Error('Missing required attributes, use either "target" or "text"');

. I would like to know if there is a way for me to catch or prevent this error or how this could be fixed. This is the only thing preventing me from switching to this library.

Hey @dweepcan,

Some sort of string needs to be returned, so we can include a space if input is empty.

Let me know if you have any other problems.

@zenorocha But this means that whatever was previously in the clipboard is destroyed which might be unexpected/annoying for the user.

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