HTML5 Number Input - Always show 2 decimal places

Question

Is there\'s any way to format an input[type=\'number\'] value to always show 2 decimal places?

Example: I want to see 0.00 instead of

Answer 1

This is a quick formatter in JQuery using the .toFixed(2) function for two decimal places.

// if this first call is in $(document).ready() it will run
// after the page is loaded and format any of these inputs

$(".my_class_selector").each(format_2_dec);
function format_2_dec() {
    var curr_val = parseFloat($(this).val());
    $(this).val(curr_val.toFixed(2));
}

Cons: you have to call this every time the input number is changed to reformat it.

// listener for input being changed
$(".my_class_selector").change(function() {
    // potential code wanted after a change

    // now reformat it to two decimal places
    $(".my_class_selector").each(format_2_dec);
});

Note: for some reason even if an input is of type 'number' the jQuery val() returns a string. Hence the parseFloat().
