Finding the Length of a String in JavaScript
by Amrit HallanWednesday, 26th October 2005
When I used JavaScript to find the length of a string for the first time, I kept testing a function something like str.length(), whereas in JavaScript length is not a function, it is a property of the string object. So here is how you find the length of a string using length property of JavaScript:
<script language="javascript" type="text/javascript"></div>
<div>var str="When a dog bites it pains.";
alert(str.length);</div>
<div></script>
<div>var str="When a dog bites it pains.";
alert(str.length);</div>
<div></script>
The function alert() in this case should throw up 26. So make a mental note that to calculate the length of a string str in JavaScript, it is str.length and not str.length().
