The split() function is really quite easy to use:

var myString = new String('red,green,blue');
var myArray = myString.split(',');

You will get:

• myArray[0] is 'red'
• myArray[1] is 'green'
• myArray[2] is 'blue'

The full syntax for the split() method is:

split([separator][, limit])

Where:

• separator is a string containing the character (or characters) which is used as the delimiter.
• limit is the maximum number of substrings to be extracted.

Using the limit parameter you can choose to extract only the first few elements from a string:

var myString = new String('red,green,blue');
var myArray = myString.split(',', 2);

and get:

• myArray[0] is 'red'
• myArray[1] is 'green'
