JSON jQuery if statement

Question

I want to be able to append the title_coupon value from the deal.options object but only if it exists. If options doesn't exist I want to get the title.coupon from data.deal. The below code works but it's obviously returning title.coupon from both deal.options and data.deal. Can someone help me construct the if statement?

This is my current code:

$.each(data.deal, function (x, deal) {
    $('#container').after('<tr><td>' + this.title_coupon + '</td><td>' + this.id + '</td></tr>');
    $.each(deal.options, function (x, options) {
        $.each(options, function (x, deal) {
            $('#container').append('<tr><td>' + this.title_coupon + '</td><td>' + this.id + '</td></tr>');
        });
    });
});

jquery is just a library of javascript, use simple if() statement and fetch conditional data — Jaykishan

A few things. This is very hard to read. You declare x multiple times, each time hiding the outer instance. The same with deal. — CodingIntrigue

How about:

$.each(data.deal, function (x, deal) {
    var found = false;
    $.each(deal.options, function (x, options) {
        $.each(options, function (x, deal) {
            $('#container').append('<tr><td>' + this.title_coupon + '</td><td>' + this.id + '</td></tr>');
            found = true;
        });
    });
    if (!found) {
        $('#container').after('<tr><td>' + this.title_coupon + '</td><td>' + this.id + '</td></tr>');
    }
});
