Make an html number input always display 2 decimal places

Question

I\'m making a form where the user can enter a dollar amount using an html number input tag. Is there a way to have the input box always display 2 decimal places?

Answer 1

So if someone else stumbles upon this here is a JavaScript solution to this problem:

Step 1: Hook your HTML number input box to an onchange event

myHTMLNumberInput.onchange = setTwoNumberDecimal;

or in the html code if you so prefer

Step 2: Write the setTwoDecimalPlace method

function setTwoNumberDecimal(event) {
    this.value = parseFloat(this.value).toFixed(2);
}

By changing the '2' in toFixed you can get more or less decimal places if you so prefer.
