Both JS and C# strings have an IndexOf method. This returns the character position if the string is matched. If it's not matched it returns -1.

If you want to check in javascript its

JavaScript

stringValue.indexOf('MyString');

If you need to check none case sensitive

JavaScript

stringValue.toLowerCase().indexOf('mystring');

If you want to check with c#

C#

stringValue.IndexOf("MyString");

Again, not case sensitive

C#

stringValue.toLower().IndexOf("mystring");

if(e1.keyCode==13){
e1.preventDefault();
}
});
});"

And I've just shown you how to do that.

Dude index off basically provide the exact location(index) of the parameter in the string.. i.e if you have a string like....

rohit_24c and if you wana get index of t than you can use indexof("t") which in result will provide you 5 than by using that index in .substring() method you can get the desired string..

For reference see the links below.
