Get only the ellipsis text using jquery

Question

Nice code, just wondered if it is possible to query and get the ellipsis text (i.e. with the dots in and not the original text)?

If I add the text

This is a long sentence

and (using the relevant css for ellipsis) it gets shortened to

This is a long sen ...

Is there a way to get the text

"This is a long sen ..." 

from the $("p") DOM object rather than the original text?

Answer 1

Try that:

function getEllipsis(command, characters) {
	for (var i = command.length; i >= 0; i--) {
		if (command.substring(0, i).length < characters) {
			if (i < command.length) {
				command = command.substring(0, i) + "...";
			}
			return command;
		}
	}
}
console.log(getEllipsis("I am a long sentence",16))
console.log(getEllipsis("But I am even longer",20))
