[#109] Add copyTest API

[timnew]

Allow zeroClipboard works as an clipboard service.
e.g:

window.zeroClipboard = new ZeroClipboard();

$('#copyTime').click(function(){
  zeroClipboard.copyTest(new Date().toLocaleTimeString());
});

This wont work because of flash restrictions. http://help.adobe.com/en_US/FlashPlatform/reference/actionscript/3/flash/system/System.html#setClipboard()

This method works from any security context when called as a result of a user event (such as a keyboard or input device event handler).

What that means is they only will setClipboard data when you either click directly on a flash object, or press a key with the flash object as focused.

closing this as wont-fix because I can't change the security restrictions.

Thanks @jonrohan
I still have some question about this.
I knows little about AS, but is that possible to do something like this in AS:

function copyText(contentText) {
  setTimeout(0, function() {
    flash.system.System.setClipboard(contentText);
  });
}

Or how about trigger the mouse click event programatically? Does that work?

[jonrohan]

I believe they still would need to originate from a mouse click. And you can't trigger one programmatically from what I could find.

My understanding is the same as @jonrohan's: after all, it wouldn't be much of a user security mechanism if a malicious developer could get around it just by programmatically invoking a synthetic click event. Good for the user, annoying and untestable for the developer....

[timnew]

Understand, and agree to @JamesMGreene. It is good for user, but really annoying.
Just for curious, does HTML5 have any enhancement about Clipboard?

[jonrohan]

@timnew sort of. It's on our roadmap https://github.com/jonrohan/ZeroClipboard/blob/master/docs/roadmap.md, but there is limited support in browsers for it currently.
