<p>The lastIndexOf() method accepts a second parameter as the starting position for the search.</p>
<p>Remember that the lastIndexOf() method searches backwards, so position 15 means start the search at position 15, and search to the beginning.</p>
<p>Position 15 is position 15 from the beginning.</p>
​
<p id="demo"></p>

var str = "Please locate where 'locate' occurs!";
var pos = str.lastIndexOf("locate", 15);
document.getElementById("demo").innerHTML = pos;
