Stop C# compiler from static type-checking

GeoffCox / CopyToClipboard.js

Created April 16, 2015 16:39

Copy HTML to clipboard in any browser

	// It may be worth making a copy of the element within <body> that is hidden
	// or even producing a section of items to copy.
	// This way you can remove any interactivity styles that make the copied content not
	// look good when pasted into other applications.
	var element = document.getElementById('ClipboardTemp');

	// This technique is simulating the user selecting these elements.
	// Think of a ControlRange as a selection of controls and then executing the command like the user pressing 'Ctrl+C'
	element.contentEditable = 'true';
	var controlRange;
