Stringing Things Along
Perform string manipulation tasks on the client with the JavaScript String object

| When Size Does Matter |

With the basics out of the way, let's now turn to some of the other string methods and properties available in JavaScript. One of the most common properties you'll find yourself using is the "length" property, which returns the length of a particular string. Consider the following example, which demonstrates:

<script language="Javascript">

// set string
var movie = "Four Weddings And A Funeral";

// print length
alert ("The length of the movie is " + movie.length + " characters");


This property can come in handy for operations which involve processing every character in a string (as you'll see shortly).

The String object also comes with a split() method, which can be used to decompose a single string into separate units on the basis of a particular separator value; these units are then placed into an array for further processing. Consider the following example, which demonstrates:

<script language="Javascript">

// set string
var friends = "Joey, Rachel, Monica, Chandler, Ross, Phoebe";

// split into array using commas
var arr = friends.split(", ");

// iterate through array and print each value
for (x=0; x<arr.length; x++)
alert("Hiya, " + arr[x]);
