React Display Line Breaks from Saved Textarea
When working with React, you may come across a scenario where you need to display line breaks from a saved textarea. By default, when you retrieve the value of a textarea in React, line breaks are represented by the “n” character. However, when rendering this value in the browser, the line breaks are not displayed as expected.
In this blog post, we will explore two solutions to this problem: using the pre
tag and using the dangerouslySetInnerHTML
property.
Using the pre Tag
The pre
tag is used to define preformatted text, preserving both spaces and line breaks. By wrapping the textarea value with a pre
tag, we can ensure that the line breaks are displayed correctly.
Here’s an example of how you can implement this solution:
{`import React from 'react'; function App() { const textareaValue = "This is anmultilinentext"; return (
{textareaValue});
}export default App;`}
The output of this code snippet will display the textarea value with line breaks:
This is a multiline textUsing dangerouslySetInnerHTML
The
dangerouslySetInnerHTML
property allows you to set the HTML content of an element. By replacing the “n” character with the HTMLtag, we can render the line breaks correctly.
Here’s an example of how you can implement this solution:
{`import React from 'react'; function App() { const textareaValue = "This is anmultilinentext"; const formattedValue = textareaValue.replace(/n/g, "
"); return ( ); } export default App;`}The output of this code snippet will display the textarea value with line breaks:
This is a
multiline
textBoth solutions achieve the desired result of displaying line breaks from a saved textarea in React. Choose the one that best fits your project’s requirements and coding style.
