Totaling the Value of Checked Checkboxes
|
|
The demonstration has checkboxes representing four items, with prices ranging from 0.00 to 55.00. There is also a text field. That text field is automatically updated with the total values of all checked checkboxes, every time one is checked or unchecked.
The JavaScript is TotalCheckedValues(). It does the following actions:
Scans each checkbox to determine whether or not it is checked,
Adds each checked value to a running total,
Formats the total into a currency decimal number, and
Displays the total in the form's text field.
