Enhancing functionality by integrating Jquery/JS with input fields and labels

I am currently facing a challenge in applying CSS to the label element when the corresponding input is selected.

After attempting and failing to use input:checked + label due to limitations in the HTML structure that cannot be altered, I seek alternative solutions.

Is there anyone who can guide me on achieving this using Javascript, JQuery, or CSS?

<div class="radio-button-container">
    <div class="radio-button">
        <input type="radio" value="QUARTER" name="frequency" id="frequencyQUARTER">
    </div>
    <div class="radio-label">
    <label for="frequencyQUARTER">New Label</label>
    </div>
</div>

Appreciate any assistance provided.

Answer №1

$('#frequencyQUARTER').change(function(){
    if($('#frequencyQUARTER').is(':checked')){

        $('.radio-label').find('label').css({color:'red'});
    }
    else{
        $('.radio-label').find('label').css({color:'yellow'});
    }
});

html 

<div class="radio-button-container">
    <div class="radio-button-holder">
        <input type="radio" value="QUARTER" name="frequency" id="frequencyQUARTER">
    </div>
    <div class="radio-label-holder">
    <label for="frequencyQUARTER">Custom Label</label>
    </div>
</div>

To dynamically assign classes based on radio button selection, you can utilize the radio change event.

Start by removing any existing classes from sibling radio elements.

Check out the code snippet below:

$(".radio-button-container input[type='radio']").on("change", function () {
    $(".radio-button-container input[type='radio']").each(function (index, element) {
        $("label[for='" + this.id + "'").removeClass("selected");
    });
    $("label[for='" + this.id + "'").addClass("selected");
});
