I want to find out the line number that a user's cursor in on in a HTML textarea element.

Is this possible using javascript and jquery?

This works with button click. Stolen from Find out the 'line' (row) number of the cursor in a textarea

​function getline() {     var t = $("#t")[0];     alert(t.value.substr(0, t.selectionStart).split("\n").length); }​ 

HTML

​<textarea rows="6" id="t"> there is no love in the ghetto so come here and get it </textarea> <input type="button" onclick="getline()" value="get line" />​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​
