Mark Fields as Required

mark-required.js

// Checks an element to see if the validation says it is required
// and if so, adds a '*' to the label using the 'for' semantic attribute.
function MarkAsRequired(element) {
    var req = $(element).attr('data-val-required');
    if (undefined != req) {
        var label = $('label[for="' + $(element).attr('id') + '"]');
        var text = label.text();
        if (text.length > 0) {
            label.append('<span style="color:red"> *</span>');
        }
    }
};

// EXAMPLE USAGE
// Setup the required markers for each type of input item.
$('input').each(function () {
    MarkAsRequired(this);
});
$('select').each(function () {
    MarkAsRequired(this);
});
