jQuery

The story so far

In the last lesson, we looked at function parameters. Parameters let you reuse a function for different purposes. Check this out:

<button onclick="BetterPiggyBank.addCoin(0.01)" ...
<button onclick="BetterPiggyBank.addCoin(0.05)" ...
<button onclick="BetterPiggyBank.addCoin(0.10)" ...
<button onclick="BetterPiggyBank.addCoin(0.25)" ...

They all call the same function:

BetterPiggyBank.addCoin = function(amount) {
  //Do something with amount.
}

Arguments can be strings

amount is a number. So…

bc.

The story so far

We're going to talk about two things:

• Function arguments
• Accumulating HTML

You can try the new app.
