Hi All,
Today we will learn about Working with Javascript Array.
So, an Array is a special kind of variable in Javascript,which holds multiple values at a time.
It's so easy to declare an Array in Javascrtipt.As we know that Array index will be starting from 0.
For Example:-
<script type="text/javascript" language="javascript">
function javascript_array()
{
//defining an Array
var employee = new Array();
employee[0] = "Vishal";
employee[1] = "Kumar";
employee[2] = "Neeraj";
employee[3] = "Pune";
employee[4] = "9876512345";
//Now accessing a value from an Array
var value = employee[0];
alert(value); //Output will be Vishal
//Now changing the value of first element
employee[0] = "Vinay";
alert(employee[0]); //Output will be Vinay
//Array.Length and Array.IndexOf works exactly like Dot Net
var array_length = employee.length;
var find_string = employee.indexOf("Neeraj");
alert(array_length); //Output will be 5 as employee has 5 element.
alert(find_string); //Output will be 2 as Neeraj is the 3rd element but Array index starts from 0
//Convert employee Array into String as with the help of toString() method
alert(employee.toString()); //Output will be Vishal,Kumar,Neeraj,Pune,9876512345
}
</script>
