Syntax:

string.search(regexp);

Here is the detail of parameters:

  • regexp : A regular expression object. If a non-RegExp object obj is passed, it is implicitly converted to a RegExp by using new RegExp(obj)

<script type="text/javascript">

var re = /apples/gi;
var str = "Apples are round, and apples are juicy.";

if ( str.search(re) == -1 ){
    document.write("Does not contain Apples" );
}else{
   document.write("Contains Apples" );
}

</script>
</body>
</html>
