How to change the text of a label?

🖊️ Title: Changing the Text of a Label: Easy Fixes for a Common Issue

Introduction:

Have you ever encountered a situation where you needed to change the text of a label dynamically? You're not alone! Many developers face this challenge, especially when interacting with radio buttons. In this blog post, we'll walk you through a common problem and provide simple solutions to help you master label text changes effortlessly.

Exploring the Problem:

Recently, one of our readers experienced difficulties when attempting to change the text of a label upon clicking a radio button. Let's take a look at their code snippet:

<asp:Label ID="lblVessel" Text="Vessel:" runat="server"></asp:Label>

<script language="javascript">
  $(document).ready(function() {

    $('#rblDiv input').click(function() {
      var selected = $("#rblDiv input:radio:checked").val();
      if (selected == "exportpack") {
        $('#lblVessel').text("NewText");
      }
    });
  });
</script>

In this example, the developer aims to change the text of the lblVessel label to "NewText" when the "exportpack" radio button is selected. However, upon testing, they encountered unexpected behavior.

Common Issue:

The issue in the provided code arises from the incorrect event binding and selector usage for the radio button click event. The script fails to target the desired radio button correctly, leading to the label not updating as expected.

💡 Solution: Binding the click event correctly

To resolve this issue, make the following modifications to your code:

1. Ensure that you have correctly defined the rblDiv element, which contains the radio buttons. For example, <div id="rblDiv"> in your HTML.

2. Use the change event instead of the click event for the radio button inputs.

<asp:Label ID="lblVessel" Text="Vessel:" runat="server"></asp:Label>

<script language="javascript">
  $(document).ready(function() {
    $('input[name="radioButtonName"]').change(function() {
      var selected = $('input[name="radioButtonName"]:checked').val();
      if (selected == "exportpack") {
        $('#lblVessel').text("NewText");
      }
    });
  });
</script>

In this updated code, we bind the change event to the radio buttons by targeting their shared name attribute, which ensures the correct selection and modification of the label text.

Now, give it a try! You should see the label text changing as expected when selecting the "exportpack" radio button.
