String object contains several useful methods which can help ease the pain of string manipulation. One of these methods is the split() function.
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'
