jQuery disable button — Disabling and enabling buttons with jQuery

Using jQuery to disable a button has many advantages as it will allow you to enable and disable the button based on user interaction. You will easily be able to use this code with other jQuery implementations. Lets get started. Starting out we are going to create a very basic HTML form that will have an input and a button, this simple form will pretend to be a search form, but will not work as part of this tutorial.

Before we do anything we include the jQuery library into our page so we are able to, well… use jQuery. We do this by simply adding the following line into the header of the page. The first thing we need to do is catch the user interaction event, there are many events to choose from but for this purpose I believe that the best event to choose will be keyup.

This means that we can trigger a set of code to run every time the users presses and releases a key within the searchInput text box. Firstly we are wrapping all our code into:. This will tell the browser to execute any code within when the page loads. We then attach the keyup event to the search input we created by using the following code. Now we have attached the event to our input, we can go ahead and add some code to achieve our desired result.

For the code to be executed when the users key has been pressed and then released we need to wrap the code within a function and put it into the keyup event trigger method. The above code is commented well to make it as easy as possible to understand, but I will go into more detail here.

First, we check to see if the input currently has any text entered. It is worth mentioning here why I chose the keyup event as opposed to, say the keydown event. If we had attached the keydown event then when we check for any input we would be checking just before some input is about to be entered, as its on key down. Where with keyup we are checking after any input has been entered or removed. This will become apparent when we can see it in action.

Depending on the outcome of the if statement, if the input is equal to nothing then we need to ensure the button is disabled, so we use the following code. Notice how this is referencing the enableOnInput class as opposed to ID, as its using a. What this code is actually doing, is setting the disabled attribute on the HTML element to disabled, so when this code is executed, the HTML button will look like the following:. This will now prevent any action when the user clicks on the button and will also grey out the button to make it visible to the user that it is disabled.

When we check to see if there is any text added to the searchInput element and we find some, we then can set the disabled attribute to false therefore enabling the button, with the following code:. This will literally remove the attribute making the button input look like the following:. This then means that the user will be free to click the submit button and submit the form. There is one last thing we must do before this simple script is complete.

Below is all the code for the whole implementation, feel free to copy, paste and use as you please. Thank you for reading this tutorial I hope it has been useful, please let me know your thoughts and any other ways you would use jQuery to enable or disabled a button. Comment and share!

Element Forms Support in all current engines. A form is a component of a web page that has form controls, such as text, buttons, checkboxes, range, or color picker controls. A user can interact with such a form, providing data that can then be sent to the server for further processing e. No client-side scripting is needed in many cases, though an API is available so that scripts can augment the user experience or use forms for purposes other than submitting data to a server. Writing a form consists of several steps, which can be performed in any order: writing the user interface, implementing the server-side processing, and configuring the user interface to communicate with the server. Any form starts with a form element, inside which are placed the controls. Most controls are represented by the input element, which by default provides a text control. To label a control, the label element is used; the label text and the control itself go inside the label element.
