The Selection API gives developers the ability to recognize the screen regions that the user has now selected and to use code to initiate user selections.
The toString() method is used to get a string representation of the selected text.
Syntax:
toString()
Parameters: None
Returns: A string representing the selection.
Example 1: In this example, we will see the basic use of the toString method.
HTML
<!DOCTYPE html> <html>
<head></head>
<body>
<h1 style="color:green">GeeksforGeeks</h1>
<h3> Web API selection toString method</h3>
<p>
Here is some text. Some more text. Some more text.
</p>
<button type="button" onclick="clickHandler()">
Click Here!!!
</button>
<div id="output"></div>
<script>
function clickHandler() {
let selection = window.getSelection();
alert(selection.toString());
}
</script>
</body>
