JavaScript Array

Previous

Next

A Java Script array is a little database holding any given type of information, and is easily accessible to you and your scripts. While there exists several built-in Document Object Model (DOM) arrays (arrays which reference HTML elements such forms and images), a custom JavaScript array can also be constructed, holding any information of your choosing.

Define An Array

The Array object is used to holding a set of data or values in a single variable name.

Define an Array object with the new keyword.

var urArray=new Array()

Creating An Array

Creating an array is different than creating a variable. Because Javascript has variables and properties associated with arrays, We have to use a special function to create a new array.

Examnple:1

<script type="text/javascript">

var urArray = new Array();
urArray[0] = "Vyom";
urArray[1] = "Techno";
urArray[2] = "Soft";

document.write(urArray[0] + urArray[1] + urArray[2]);

</script>

Output

VyomTechnoSoft

Accessing Arrays in JavaScript

We can access an array element by referring to the the element's index number and name of the array .

document.write(urArray[1])

The above code displays the second element of the array named urArray

Modifying the Contents of an Array

You can modify the contents of an array by specifying a value for a given index number:

urArray[1] = "vyomtechnosoft?"

The Array object contains 10 functions.All functions are used with the array object.

JavaScript join Function
JavaScript concat Function
JavaScript pop Function
JavaScript push Function
JavaScript reverse Function
JavaScript shift Function
JavaScript slice Function
JavaScript splice Function
JavaScript sort Function
JavaScript unshift Function
