How To Make Input Readonly In Jquery

In this blog post, we will discuss how to make an input field readonly using jQuery. A readonly input field is one where the user can’t change its value, but the value can still be submitted with the form.

Prerequisites

To follow along with this tutorial, you should have a basic understanding of HTML, CSS, and JavaScript, as well as some experience working with jQuery.

Make sure to include the jQuery library in your project before proceeding.

Method 1: Using the .prop() Method

The first method we’ll discuss is using the .prop() method provided by jQuery. This method allows you to both get and set the properties of an element.

Here’s how to use the .prop() method to make an input field readonly:

    $('input').prop('readonly', true);
    

This line of code selects all input elements and sets their ‘readonly’ property to true, making them readonly.

If you want to target a specific input field, you can use an ID, class, or other attribute to select it. Here’s an example targeting an input field with the ID ‘myInput’:

    $('#myInput').prop('readonly', true);
    

Method 2: Using the .attr() Method

Another method to make an input field readonly is by using the .attr() method provided by jQuery. This method is used to get and set attributes on the selected elements.

Here’s how to use the .attr() method to make an input field readonly:

    $('input').attr('readonly', true);
    

Similar to the previous method, you can use an ID, class, or other attribute to target a specific input field. Here’s an example targeting an input field with the ID ‘myInput’:

    $('#myInput').attr('readonly', true);
    

Removing Readonly Attribute

If you want to remove the readonly attribute from an input field, you can use the .removeAttr() method provided by jQuery:

    $('#myInput').removeAttr('readonly');
    

This will make the input field editable again.

Conclusion

In this blog post, we discussed two methods for making input fields readonly in jQuery: using the .prop() and .attr() methods. Both methods are easy to use and can be applied to one or multiple input fields at once.
