How to Enable Disabled Input Fields in jQuery Using the Correct Method?

How to Manipulate the "Disabled" Attribute Using jQuery

Problem Statement

I have disabled input fields on my web page and want to enable them when a link is clicked. I've attempted to use jQuery to remove the "disabled" attribute, but it has not been successful.

jQuery Code:

$("#edit").click(function(event){
   event.preventDefault();
   $('.inputDisabled').removeAttr("disabled")
});

Problem Analysis

The issue here is that jQuery should use the prop() method to set or retrieve element properties, rather than using attr() or removeAttr(), especially for boolean attributes like "disabled."

Solution

$("#edit").click(function(event){
   event.preventDefault();
   $('.inputDisabled').prop("disabled", false);
});

By using prop(), we explicitly set the "disabled" property to false, enabling the input fields and allowing users to interact with them.

Why Use prop()?

While attr() can be used to retrieve or modify HTML attributes, prop() is specifically designed to manage element properties. For boolean attributes like "disabled," "checked," and "readonly," prop() operates directly on the underlying property and ensures correct behavior in modern browsers.

Pre-jQuery 3.0, removeAttr() would also set the corresponding property to false, which is now considered incorrect behavior for handling boolean attributes. Therefore, always use prop() for enabling or disabling elements with jQuery to avoid potential issues.
