Get last line of HTML with Javascript

Question

How can I get the last line of HTML text with Javascript?

For example, a HTML request returns this response:

<span>blah blah blah
ha ha ha ha
tatatatata

How would I get the last line "tatatatata"?

Answer 1

var html = document.getElementById('some_element').innerHTML.split(/\r?\n/);
alert(html[html.length - 1]);

Split by /\r?\n/ to break the HTML into lines, then grab the last element of the array.

Note: since this is HTML, you may want to split by /<br(?: \/)?>/ or /<br>/, depending on the situation.

Answer 2

$('#your_span').html().split(/\r?\n/).pop()
