Tips on accessing the text content of a dt element with prototype

Below is some HTML code that I am working with:


        <dl>
            <dt><label>test</label></dt>
            <dd><input id="someid" type="checkbox" onchange="opConfig.reloadPrice()" class="product-custom-option"></dd>
            <dt><label>test</label></dt>
            <dd><input id="someid" type="checkbox" onchange="opConfig.reloadPrice()" class="product-custom-option"></dd>
            <dt><label>test</label></dt>
            <dd><input id="someid" type="checkbox" onchange="opConfig.reloadPrice()" class="product-custom-option"></dd>
            <dt><label>test</label></dt>
            <dd><input id="someid" type="checkbox" onchange="opConfig.reloadPrice()" class="product-custom-option"></dd>
        </dl>

        <script>
            reloadPrice: function() {
                var config = this.config;
                var skipIds = [];
                $$('body .product-custom-option').each(function(element){
                    //todo
                });
            </script>
    

I am trying to extract the text of the label within the dt element in a loop. There is a function named 'reloadprice' in my prototype function which runs on the change event. How can I retrieve the label text using prototype? Any assistance would be greatly appreciated.

Answer №1

When you're using Prototype, keep in mind that it extends the DOM. Here's a helpful tip for utilizing this feature:

  $$('.product-custom-option').each(function(element){
      // The 'element' here is a DOM node extended by prototype
      console.log(element.up().previous().down().innerHTML);
  });
