What is Highlighted Text in JavaScript and Why is it Important?
Highlighted text in JavaScript is a selected portion of text on a web page that is visually distinguished from surrounding text by color or other means. This selection is made by the user either by clicking and dragging the mouse or by keyboard input. Highlighted text is important because it can be used to perform various actions based on the selected text. For example, it can be used to apply formatting, to perform a search or to copy the selected text to the clipboard. In JavaScript, it can be accessed and manipulated using the window.getSelection() method. This method returns a Selection object that contains the selected text and its properties. With this object, you can get the selected text, its position on the page, and more.

How to Use CSS for Highlighting Text in JavaScript: A Beginner’s Guide
CSS is a powerful tool for styling web pages and JavaScript allows us to dynamically manipulate elements on a page. One common task is highlighting text based on user input or search results. Here’s how to use CSS to highlight text in JavaScript.
Step 1: Select the Element
First, we need to select the element that we want to highlight. This can be done with the `querySelector` method in JavaScript. For example, if we want to highlight a paragraph with an ID of “myParagraph”, we would use:
“`javascript
const myParagraph = document.querySelector(“#myParagraph”);
“`
Step 2: Add the Highlighting CSS
Once we have selected the element, we can add CSS to highlight it. This can be done by adding a class to the element and defining the CSS for that class in our stylesheet. For example, we can add a class called “highlight” to the selected paragraph:
“`javascript
myParagraph.classList.add(“highlight”);
“`
Then, in our stylesheet, we can define the CSS for the “highlight” class:
“`css
.highlight {
background-color: yellow;
}
“`
This will set the background color of our selected paragraph to yellow when the “highlight” class is added.
Step 3: Remove the Highlighting
Finally, we may want to remove the highlighting when it is no longer needed. This can be done by removing the “highlight” class from the element using the `classList.remove` method:
“`javascript
myParagraph.classList.remove(“highlight”);
“`
With these simple steps, we can use CSS to highlight text in JavaScript. Whether it’s for user input validation or search result highlighting, this technique is a useful tool for any web developer.

Integrating Highlighted Text into Your SPA (Single Page Application) using React and jQuery
If you’re building a Single Page Application (SPA) with React and jQuery, you may want to allow your users to highlight text and save those highlights for later reference. This functionality can greatly improve the user experience and make your application more useful.
One way to accomplish this is by using the popular text highlighting library called “get highlighted text javascript”. This library provides a simple way to extract highlighted text from a web page and save it to a database. In this tutorial, we will walk through the process of integrating this library into your SPA using React and jQuery.
Step 1: Install get highlighted text javascript
First, you will need to install the get highlighted text javascript library. You can do this by navigating to the library’s GitHub page and downloading the latest version.
Once you have downloaded the library, include it in your project by adding the following line of code to your project:
<script src="path/to/get-highlighted-text.js"></script>
Step 2: Create a Highlight Component
Next, you will need to create a new React component called “Highlight” that will allow your users to highlight text and save those highlights. This component should include the following code:
class Highlight extends React.Component {
render() {
return (
<div className="highlight"></div>
);
}
}
The “highlight” class in the above code should be styled using CSS to provide a visual cue to the user when they are highlighting text.
Step 3: Add jQuery Event Listeners
Now that you have created your Highlight component, you can add jQuery event listeners to allow your users to highlight text. Here is an example of how you can add event listeners to a specific element:
$(document).ready(function() {
$("#my-text-element").mouseup(function() {
var highlightedText = getHighlightedText();
saveHighlight(highlightedText);
$(".highlight").append(highlightedText);
});
});
In the above code, the “mouseup” event is triggered when the user releases the mouse button. The getHighlightedText() function is used to extract the highlighted text, which is then saved to a database using the saveHighlight() function. Finally, the highlighted text is appended to the Highlight component using jQuery’s “.append()” method.
Conclusion
By following these steps, you can easily integrate the get highlighted text javascript library into your SPA and provide your users with the ability to highlight and save text. This functionality can greatly improve the user experience and make your application more useful.
