The Array Object
An array is an ordered set of data, similar to a table. In JavaScript, arrays are one-dimensional, meaning that you can create a table of data with one column (and as many rows as you like). Arrays are powerful programming tools because they allow you to create a structured set of data, any item of which can be accessed with short statement.
To create an array you need to create a new array, and then populate it with data, as in the following example:
Example:
<script language="JavaScript">
<!--
monthArray = new Array(12)
// note that array numbering starts at zero;
// this method does not work for Netscape 2.0x
// on account of bugs in the JavaScript implemenation
monthArray[0] = 'January'
monthArray[1] = 'February'
monthArray[2] = 'March'
monthArray[3] = 'April'
monthArray[4] = 'May'
monthArray[5] = 'June'
monthArray[6] = 'July'
monthArray[7] = 'August'
monthArray[8] = 'September'
monthArray[9] = 'October'
monthArray[10] = 'November'
monthArray[11] = 'December'
/* The following code writes the values of the array
to the document
*/
var x = 0
while ( x <=11 ) {
document.write('monthArray[' + x + '] = ' + monthArray[x] + '<br>')
x++
}
// -->
</script>
Below you will see the output from this script:
