· The array object is used to store a set of values in a single variable name.
· Arrays are created using a constructor, just like other objects. The Array() constructor uses the following format.
variablename = new Array(); or variablename = new Array([size]);
· There are two ways of adding values to an array.
Example-1
<html>
<body>
<script language="javascript">
var arr = new Array();
arr[0] = “PHP”;
arr[1] = “VB”;
arr[2] = “C++”;
for(x in arr)
{
document.write(arr[x]+”<br/>”);
}
</script>
</body>
</html>
Example-2
<html>
<body>
<script language="javascript">
var arr = new Array(“php”,”vb”,”c++”);
for(x in arr)
{
document.write(arr[x]+”<br/>”);
}
</script>
</body>
</html>
Ø Accessing Arrays
· You can refer to a particular element in an array by referring to the name of the array and the index number.
· The index number starts at 0.
document.write(arr[0]);
Ø Modify values in existing Arrays
To modify a value in an existing array, just add a new value to the array with a specified index number.
arr[2] = “sad”;
document.write(arr[2]);
