Short Answer

Expert verified

Answer: To create a read-only text field and store text in it using HTML and JavaScript, complete the following steps: 1. Create an HTML file with a basic page structure. 2. Add a text field using the "input" element with the "readonly" attribute, like this: ``. 3. Use JavaScript to make the text field read-only, if not already done using the "readonly" attribute: `document.getElementById("myTextField").readOnly = true;`. 4. Store text in the text field using JavaScript: `document.getElementById("myTextField").value = "This is read-only text.";`. The resulting HTML file should display a read-only text field with the text "This is read-only text." stored inside it.

Step by step solution

Create the HTML file

Begin by creating an HTML file. This file will include the code needed to create a basic web page. You can use any text editor or integrated development environment (IDE) to create this file. Save it as "read_only_text_field.html" or any other name with an ".html" file extension.

Add a text field in the HTML file

Inside the HTML file, we need to add a text field using the "input" element. To do so, add the following code within the "body" section of the HTML file: ```html ``` This code creates a text field with the id "myTextField" for later manipulation using JavaScript.

Make the text field read-only

There are two ways to make the text field read-only: directly in HTML or using JavaScript. Method 1 - Using HTML: Add the "readonly" attribute to the "input" tag, like this: ```html ``` Method 2 - Using JavaScript: You will need to use JavaScript to manipulate the text field's properties. Add this inside your "script" tag or in an external JavaScript file: ```javascript document.getElementById("myTextField").readOnly = true; ```

Store text in the text field

Since you are looking to store text in the text field, we'll assume you want to do this programmatically, using JavaScript. Add the following JavaScript code inside the "script" tag or an external JavaScript file: ```javascript document.getElementById("myTextField").value = "This is read-only text."; ```

Final HTML file

Here is a full HTML file incorporating the discussed code snippets: ```html Read-Only Text Field ``` Now, when you open the HTML file in a web browser, you will see a read-only text field with the text "This is read-only text." stored inside it.
