The style of the button label does not persist when onChange occurs

Encountered an interesting issue here. There is a button designed for selection purposes, similar to a select item. Here's the code snippet:

<button class="btn btn-primary dropdown-toggle" style="width: 166%;" 
        type="button" id="dropdownMenuButton" data-toggle="dropdown" 
        aria-haspopup="true" aria-expanded="false">
   <span id="dropdown_button" style="width: 166%;">
     <img src="wp-content/themes/directory2/images/closest.png" />
          10 Closest Amenities</span>
   <span class="caret" style="margin-top: 9px;float: right;"></span>
</button>

To update the text within the button/select using jQuery, this code is used:

$(document).on('click', '.dropdown_anchor', function(event) {
    var index = $(this).data('index');
    var title = $(this).data('title');
    populate_list(index);
    dropdownButtonText(title);
});

The function responsible for updating the button text is defined as follows:

function dropdownButtonText(text) {
    $("#dropdown_button").text(text);
}

The challenge arises when the button loses its set width after the text change, going from 166% to, say, 87%. How can we ensure that the button maintains its width even after the text change?

Your insights and time are greatly appreciated. Thank you.

Answer №1

When the text on a button has fewer characters than the previous text, the width of the button may change. To prevent this, you can set a specific width for the button using CSS.

#dropdown_button {
width: 100px; // Here is an example
}

Another option is to use min-width to ensure that the button never goes below a certain width.

#dropdown_button {
    min-width: 100px; // Here is an example
    }

Answer №2

Prior to altering the text, you may want to capture the width of the elements:

 $(document).on('click', '.dropdown_anchor', function(event) {
          var index = $(this).data('index');
          var title = $(this).data('title');
          var width = $(this).outerWidth();
          populate_list(index);
          dropdownButtonText(title, width);
      });

Subsequently, utilize that width within the new function.

 function dropdownButtonText(text, width) {
    $("#dropdown_button").css("width", width).text(text);
  }

It is important for the button to be displayed as inline-block.

Answer №3

Give this a shot in your stylesheet:

.btn-primary {
   width: 500px;
}

Answer №4

My attempt is shown below.

<div class="dropdown">
    <button id="btnTest" class="btn btn-primary dropdown-toggle" type="button" data-toggle="dropdown" style="width: 80%;">Example Dropdown
    <span class="caret"></span></button>
    <ul id="demolist" class="dropdown-menu">
      <li><a href="#">HTML</a></li>
      <li><a href="#">CSS</a></li>
      <li><a href="#">JavaScript</a></li>
    </ul>
  </div>
</div>
<script type="text/javascript">
$('#btnTest').click(function() {
   console.log("Test");
});
$('#demolist li').on('click', function(){
    var selectedText = $(this).text();
    console.log(selectedText);
    $("#btnTest").html(selectedText+'&nbsp;&nbsp;<span class="caret"></span></button>');
});
</script>
