The example in this article describes the method of JavaScript searching for a string and returning the search results to the string. Share it with everyone for your reference. The details are as follows:

The JavaScript operation string has a match method for searching the string. If the specified string is found, the search string is returned. If not found, null is returned. The match method is case-sensitive

<!DOCTYPE html>
<html>
<body>
<script>
var str="Hello world!";
document.write(str.match("world") + "<br>");
document.write(str.match("World") + "<br>");
document.write(str.match("worlld") + "<br>");
document.write(str.match("world!"));
</script>
</body>
</html>
Copy after login

Return results:

world
null
null
world!
