Calculating text width

Question

I\'m trying to calculate text width using jQuery. I\'m not sure what, but I am definitely doing something wrong.

So, here is the code:

var c = $(\'.c         


        

Answer 1

I had trouble with solutions like @rune-kaagaard's for large amounts of text. I discovered this:

$.fn.textWidth = function() {
	var width = 0;
	var calc = '' + $(this).html() + '';
	$('body').append(calc);
	var last = $('body').find('span.textwidth:last');
	if (last) {
			var lastcontent = last.find('span');
			width = lastcontent.width();
			last.remove();
	}
	return width;
};
