Search a String JavaScript - (Like strstr in php)

you want to search a keyword(String) within a given String using Javascript? need a function like strstr() in php? Then you should look at this code, like in php I haven't seen a built in function to do this but by using some regular expression you can accomplish this task

<script type="text/javascript">
//visit kuppiya.com
var myKey = /kuppiya/;
var myStringVar = "I Love kuppiya";
var myMatch = myStringVar.search(myKey);
if(myMatch != -1)
{
alert("Wow There is a match "); 
}
else
{
alert("hmmm no match");
} 
</script>
