Hi,

Go with indexOf. I have made a sample below for you try it.

<html xmlns="http://www.w3.org/1999/xhtml">
<head runat="server">
    <title></title>
    <script type="text/javascript">

        var inputString = 'Hello this is a test string'; //test input
        var wordToFound = 'this';
        if (inputString.indexOf(wordToFound) == -1) {
            alert(wordToFound + ' Not Found');
        }
        else {
            alert(wordToFound + ' Found');
        }

        //Now let's do another test 
        wordToFound = 'how';
        if (inputString.indexOf(wordToFound) == -1) {
            alert(wordToFound + ' Not Found');
        }
        else {
            alert(wordToFound + ' Found');
        }
        
   
    </script>
</head>
<body>

</body>
</html>
