How to stop type text textbox in Javascript

Have you ever had a textbox where you wanted to prevent the user from typing any text? Perhaps you were building a calculator and you didn't want users to enter anything in the display textbox. Or maybe you wanted to create a read-only textbox that couldn't be edited. Whatever the reason, there are several ways to stop users from typing in a textbox using Javascript.

Method 1: Using the disabled attribute

The simplest way to prevent users from typing in a textbox is to disable it using the disabled attribute. This will make the textbox uneditable and grayed out, making it clear to the user that they can't enter any text. Here's how you can do it:

<input type="text" disabled />

In the above code, we've added the disabled attribute to the input element. This will disable the textbox and prevent users from typing in it. Note that you can't set the value of a disabled textbox using Javascript, so if you need to set a default value, you'll need to do it using the value attribute before disabling the textbox.

Method 2: Using the readonly attribute

If you want to allow users to select and copy text from a textbox but don't want them to be able to edit it, you can use the readonly attribute. This will make the textbox uneditable, but it won't be grayed out, so the user may not realize that they can't edit it. Here's how you can do it:

<input type="text" readonly />

As with the disabled attribute, you can't set the value of a readonly textbox using Javascript, so you'll need to set the value using the value attribute before making the textbox readonly.

Method 3: Using Javascript to prevent typing

If you need more control over when users can and can't type in a textbox, you can use Javascript to prevent typing. Here's how you can do it:

<input type="text" id="myTextbox" />

<script>
var myTextbox = document.getElementById("myTextbox");

myTextbox.addEventListener("keydown", function(event) {
    event.preventDefault();
});
</script>

In the above code, we've added an event listener to the input element that listens for the keydown event. When this event fires, we call the preventDefault() method on the event object to prevent the default behavior (i.e. typing) from occurring. This will effectively disable the textbox and prevent users from typing in it. Note that this method won't work if users are copy-pasting text into the textbox.

These are three ways you can stop users from typing in a textbox using Javascript. Choose the one that best suits your needs and use it to create a better user experience for your users.
