Chapter 1

The JavaScript’s ready, and the button no longer tries to submit

the form... but right now, getBoardsSold() never runs, either.

This shouldn’t be too hard to x, though:

Running getBoardsSold() from the web form

Can’t we just run the

getBoardsSold() function

whenever someone clicks on

“Show Me the Money”?

<input value=”Show Me the Money” type=”button” />

function getBoardsSold() { ... }

Any time this button is clicked...

...this JavaScript function

needs to get called.

A Question For JavaScript

JavaScript, we need to run a function from our HTML. Can you help us out?

Oh, well I’m incredibly exible when it comes to calling functions from a

web page. Just use one of my event handlers in your HTML. You can use

onBlur() for when someone leaves a eld, or onClick(), for when a

user clicks... how about onChange(), for when a value changes... or there’s

onFocus()... wait, wait, I’ve got more... what do you mean, out of time?
