How to Append Text Data with Line Breaks Using jQuery

When building interactive web applications, one common requirement is to collect user input from forms and display it in a clean and readable format. If you're using jQuery to handle this process, you might encounter a challenge: appending the input data with proper line breaks. This guide will guide you through this problem and provide you with an effective solution.

The Problem

Imagine you have a form where users enter their name, age, email, country, and a message. When the user clicks a button to submit this form, you want to display the entered data in a structured way. However, you may find that all the information appears in a single line, like this:

What you actually want is to format it like this:

Why You Might Face This Issue

The primary cause of this formatting issue lies in how you're appending the text to the output area. In JavaScript, using newline characters like \n or carriage returns \r\n won’t translate to line breaks in HTML. Consequently, you need an alternative approach to make your output visually appealing.

The Solution

To achieve your desired output format, you'll need to wrap each line of your data in paragraph <p> tags. This will ensure that each piece of information is displayed on a separate line when appended to the output area.

Step-by-Step Implementation

Here's a breakdown of how to correctly append the input data with line breaks using jQuery:

Set Up Your HTML Structure: Ensure you have a simple form to collect user inputs, and a div to display the results.

Use Template Literals: You can utilize ES6 template literals to keep your code clean and readable.

Append Each Line: Use a loop to append each line to your output area.

Here's the adapted code snippet:

Key Changes to Note:

Using <p> Tags: Each piece of data is enclosed in <p> tags, allowing it to take up its own line in HTML.

Function Loop: Instead of trying to insert each piece of information with text nodes, we directly append the <p> formatted data.

Conclusion

With these simple adjustments, you can effectively display multiline data from forms using jQuery. By wrapping your data in HTML elements (like <p>), you'll ensure that users see their inputs formatted clearly and sorted by line.
