Locate the nearest span element and update its CSS class

On my page, there is a section with the following code:

<h5 class="text-center" id="findStore" style="width:260px">
    <a data-toggle="collapse" data-parent="#accordion" href="#@item.ProductId" aria-expanded="true" aria-controls="@item.ProductId" style="color: @item.ProductTextColor;font-size:19px;text-decoration: none;" class="text-center">
         <span class="text-center" style="margin-left:14%">FIND A STORE</span> 
         <span id="chevvy" class="glyphicon glyphicon-chevron-down pull-right"></span>
    </a>
</h5>

When the user clicks on "Find Store", I want to change the class of a specific span tag (with ID chevvy) from chevron-down to chevron-up. Here's the code I am trying to use for this:

$('h5:not(#nutritionInfo)').click(function () {

if ($(this).find('span').hasClass("glyphicon glyphicon-chevron-down")) {
    $(this).find('span').removeClass("glyphicon glyphicon-chevron-down");
    $(this).find('span').addClass("glyphicon glyphicon-chevron-up");
} else {
    $(this).find('span').removeClass("glyphicon glyphicon-chevron-up");
    $(this).find('span').addClass("glyphicon glyphicon-chevron-down");
}
});

However, this code ends up applying the chevron transformation to "Find Store" as well, resulting in two chevrons being displayed. How can I specifically target the other span tag with ID chevvy and change its chevron class?

Answer №1

Ensure your find('span') is not selecting all spans, but specifically the one you want by narrowing down with additional selectors, such as find('span.glyphicon').

You can also optimize your code by utilizing jQuery's toggleClass feature to switch between -up and -down classes dynamically without needing if-else statements:

$('h5:not(#nutritionInfo)').click(function () {
    $(this).find('span.glyphicon').
        toggleClass('glyphicon-chevron-down glyphicon-chevron-up');
});

Consider using a pseudoclass instead of an id for determining which h5 elements should exhibit this behavior. For instance, you could have multiple instances like:

<h5 class="toggle-my-chevron">...</h5>
<h5 class="toggle-my-chevron">...</h5>

All managed by a single function like:

$('.toggle-my-chevron').click(function () {
    $(this).find('span.glyphicon').
        toggleClass('glyphicon-chevron-down glyphicon-chevron-up');
});

Answer №2

If you want to toggle the class of a span with the glyphicon class selector, you can use the following code:

Important Note - Make sure that if you have multiple spans with the same id like chevvy, each one should have a unique id for proper functionality.

$('h5:not(#nutritionInfo)').click(function () {
  var span = $(this).find('.glyphicon');
  if ($(span).hasClass("glyphicon-chevron-down")) {
    $(span).removeClass("glyphicon-chevron-down").addClass("glyphicon-chevron-up");
  } else {
    $(span).addClass("glyphicon-chevron-down").removeClass("glyphicon-chevron-up");
  }
});

Answer №3

To enhance the performance of your website, it is essential to streamline both your HTML and CSS codes by eliminating redundant elements in your snippet. This will also contribute to improving the efficiency of your JavaScript functions. Consider implementing the following changes:

HTML

<h3 class="text-center" id="searchLocation">
  <a href="#" class="">SEARCH FOR A LOCATION</a>
</h3>

CSS

You can add an icon image using CSS like this:

h3 a {padding-left: 10px; background: transparent url('arrow-right.png') 0% 50% no-repeat;}
h3 a.active {background: transparent url('arrow-left.png') 0% 50% no-repeat;}

JavaScript/jQuery

$('h3 a').click(function(){
  $(this).toggleClass('active');
  return false;
});
