How to check if a string has a certain piece of text in JavaScript?
The jQuery search() method is used to check whether a string contains a certain text in JavaScript.
You can try to run the following code to check whether “Tutorialspoint: Free Video Tutorials” contains the “Free Video” text in JavaScript or not:
<html>
<head>
<title>JavaScript String search() Method</title>
</head>
<body>
<script>
var re = "Free Video";
var str = "Tutorialspoint: Free Video Tutorials";
if ( str.search(re) == -1 ) {
document.write("Does not contain" );
} else {
document.write("Contains" );
}
</script>
</body>
</html>
