If you are working with a select dropdown option box. And want to disable the selection based on the dropdown value.
So, in this tutorial, you will learn how to disable select options based on their selection values using jQuery.
jQuery Disable Select Option Based on Value
You can use the following steps and disable the select option based on the value using jQuery:
- Step 1: Include jQuery Library
- Step 2: HTML Select Element
- Step 3: jQuery Code
Step 1: Include jQuery Library
First, make sure you have the jQuery library included in your HTML file. You can include it by adding the following line within the <head> section of your HTML file:
<script src="https://code.jquery.com/jquery-3.6.0.min.js"></script>
Step 2: HTML Select Element
Create a <select> element in your HTML file with multiple <option> elements. Each <option> should have a value attribute that you can use to identify it.
<select id="mySelect"> <option value="1">Option 1</option> <option value="2">Option 2</option> <option value="3">Option 3</option> </select>
Step 3: jQuery Code
Use the following jQuery code to disable select dropdown options based on their values:
$(document).ready(function() {
$('#mySelect').change(function() {
var selectedValue = $(this).val();
disableOptions(selectedValue);
});
function disableOptions(value) {
$('#mySelect option').each(function() {
if ($(this).val() === value) {
$(this).prop('disabled', true);
} else {
$(this).prop('disabled', false);
}
});
}
});
Save the above given HTML and jquery code in your file and open it in a web browser. Now, whenever you select an option from the dropdown, that option will be disabled, preventing it from being selected again.
Conclusion
That’s it! You’ve successfully learned how to disable select options based on their values using jQuery.
