Creating a dropdown menu with a variety of value attributes and corresponding display text

Currently, I am working on a language translation system that involves using the Google Translator API. To make this process smoother, I need to create a dropdown list of languages and pass their corresponding codes to the API. Initially, I attempted this using Bootstrap, but encountered some challenges. While I am comfortable implementing this feature in HTML, I am interested in incorporating it into Bootstrap for a more polished look. Below is my current attempt:

<div class="btn-group"> <a class="btn btn-default dropdown-toggle btn-select2" data-toggle="dropdown" href="#">Select a Region <span class="caret"></span></a>
        <ul class="dropdown-menu">
            <li><a href="#" >Spanish</a></li>
            <li><a href="#">Sinhala</a></li>
            <li><a href="#">Portuguese</a></li>
            <li class="divider">Arabic</li>
            <li><a href="#">Quebec</a>
            </li><li><a href="#">Ontario</a>
            </li><li><a href="#">British </a>
            </li>
        </ul>
    </div>

I would appreciate any suggestions or guidance on how to proceed with this task. Thank you in advance for your help.

Answer №1

Make sure to include a custom data-* attribute in your a elements. Implement a click event that retrieves the value of this custom attribute and sends it to the API.

Example:

<div class="btn-group"> 
   <a class="btn btn-default dropdown-toggle btn-select2" data-toggle="dropdown" href="#">Select a Region <span class="caret"></span>
   </a>
   <ul class="dropdown-menu">
       <li><a data-code="spanishCode" href="#" >Spanish</a></li>
       <li><a data-code="sinhalaCode" href="#">Sinhala</a></li>
       <li><a data-code="portugueseCode" href="#">Portuguese</a></li>
       <li class="divider">Arabic</li>
       <li><a data-code="quebecCode" href="#">Quebec</a></li>
       <li><a data-code="ontarioCode" href="#">Ontario</a></li>
       <li><a data-code="britishCode" href="#">British </a></li>
   </ul>
</div>

Implementing Click Event:

$('ul.dropdown-menu li a').on('click',function(){
     var code=$(this).data('code');
     //Include this code in your API call to retrieve the response
});

Explanation and Application

  1. The data-* attributes are utilized for storing personalized data that is specific to the webpage or application.
  2. By using the data-* attributes, we have the capability to include customized data attributes on all HTML elements.
  3. This custom data can then be accessed in the JavaScript of the page to enhance user interaction (without relying on Ajax requests or server-side database queries).

The data-* attributes are comprised of two parts:

The attribute name should not contain any uppercase letters, and must be at least one character long after the prefix "data-". The attribute value can be any string.

Please Note: User agents will completely disregard custom attributes prefixed with "data-".

<div class="btn-group"> <a class="btn btn-default dropdown-toggle btn-select2" data-toggle="dropdown" href="#">Select a Region <span class="caret"></span></a>
        <ul class="dropdown-menu">
            <li><a href="#" data-langcode = "sp" class="langclass">Spanish</a></li>
            <li><a href="#" data-langcode = "en" class = "langclass">english</a></li>

        </ul>
    </div>

Utilizing jQuery

$(".langclass").on("click",function(){
    var code = $(this).data("langcode");//call this code in your function
     callableFunction(code);
})
