Step by step solution

Create an HTML Text Field using Form and Input Tags

To create a text field in an HTML document, we will use the `form` and `input` tags. We can assign an `id` attribute to the text field so that we can refer it in JavaScript code. ```html ```

Make the Text Field Read-Only using the "readonly" Attribute

To make the text field read-only, simply add the `readonly` attribute to the input element. This prevents users from editing the text. ```html ```

Store Text in the Text Field using JavaScript

To store text in the text field, we will use JavaScript. First, let's create a function called `storeText()` and use the `getElementById()` method to access the text field element by its `id`. Use the `value` property to store the desired text inside the text field. ```javascript function storeText() { document.getElementById("textBox").value = "This is a read-only text!"; } ```

Add the JavaScript Function to the HTML Document

Add the JavaScript function inside a ` ``` Now, load the HTML document in a web browser, and clicking the "Store Text" button will store the text "This is a read-only text!" in the read-only text field.
