Troubleshooting issue with jQuery validation functionality not functioning properly with select dropdown

My default validator settings include displaying a red error message when validation fails.

However, it works on Input and textareas, but not on select.

$.validator.setDefaults({
        ignore: "",
        errorPlacement: function(error, element) {
        element.attr('title', error.addClass('error').text());
        element.attr('placeholder', error.addClass('error').text());
        element.attr('title', error.text());
       },
       highlight: function(element, errorClass, validClass) {
        $(element).addClass(errorClass).addClass('error').removeClass(validClass).removeClass('valid');
        $(element.form).find("input[id=" + element.id + "]").addClass(errorClass).addClass('error');
        $(element.form).find("select[id=" + element.id + "]").addClass(errorClass).addClass('error');
        },
        unhighlight: function(element, errorClass, validClass) {
        $(element).removeClass(errorClass).removeClass('error').addClass(validClass).addClass('valid');
        $(element.form).find("input[id=" + element.id + "]").removeClass(errorClass).addClass(validClass).addClass('valid');
        $(element.form).find("select[id=" + element.id + "]").removeClass(errorClass).addClass(validClass).addClass('valid');
        }
    });

CSS

.error {
    color:#F00 !important;border:1px solid red !important;
}
.valid {
    color:#060 !important;
}

Answer №1

Utilizing a component that employs a span to display the text results in the select option not being visible, only the span is shown (inspect using Firebug) and requires adjusting the span's color.

The following HTML code has been generated:

<div class="selector" id="uniform-vehicleID" style="width: 348px;">
    <span style="width: 331px; -moz-user-select: none;">Select One...</span>
    <select data-msg-required="Choose Vehicle" data-rule-required="true" class="form-control error" id="vehicleID" name="vehicleID" aria-required="true" title="Choose Vehicle" placeholder="Choose Vehicle" aria-invalid="true"> 
        <option disabled="disabled" selected="" value="" style="color: red ! important;">Select One...</option> 
        <option value="1">Luxury Sedan or Towncar</option> <option value="2">Stretch Limousine</option> 
        <option value="3">SUV Limousine</option> <option value="4">Business Class Van</option> 
    </select>
</div>

The select element has an 'error' class, but due to the presence of the span, only the span content is displayed to the user.

If all selects utilize the same component, you can target the span with the following change:

$(element.form).find("select[id=" + element.id + "]").removeClass(errorClass).addClass(validClass).addClass('valid');

Replace it with:

$(element.form).find("select[id=" + element.id + "]").parent().find("span").removeClass(errorClass).addClass(validClass).addClass('valid');

By using .parent, the <div class="selector"... will be targeted, and .find("span") retrieves the actual text displayed on the screen.
