Well I have a question about jQuery, what the following code would look like Javascript Puro using the jQuery?

function writeTotal(value){
    var total = document.getElementById('total');
    total.innerHTML = floatToMoneyText(value);
}

A reduced form:

function writeTotal(value) {
    $('#total').html(floatToMoneyText(value));
}

That one floatToMoneyText probably could also be converted to jQuery, but would have to know what you do exactly in it

How about testing the parameter value to see if it is null/empty:

function writeTotal(value) {

var innerHtml = "";

if (value === window.undefined || value === null || value === "") {
    innerHtml = "R$ 0,00";
}
else {
    innerHtml = floatToMoneyText(value);
}

$('#total').html(innerHtml);
};

    The body of the function could be replaced by $('#total').html(value ? floatToMoneyText(value) : "R$ 0,00");, but I think that would be the responsibility of the function floatToMoneyText

  • Clear-cut! use a ternary condition It’s a good one, particularly I like to check whether it’s null or empty, makes it easier for human reading. I also agree, create a validation within the function floatToMoneyText.
