I tried of checking contains option using jquery for the birthday but its getting exception

var _dob = "4/10";
// this line doesn't work
var _adob = _dob.contains('/') ? _dob.Split('/') : _dob.Split('-');
$('#Month').val(_adob[0]);
$('#Day').val(_adob[1]);

but i can't able to split.. its resulting in error on getting _adob itself

Try this:

var _dob = "4/10";
var _adob;
if (_dob.indexOf("/") >-1) {
    _adob = _dob.split("/");
} else {
    _adob - _dob.split("-");
}

Direct Answer

indexOf(something)>-1

var _dob = "4/10";
var _adob = _dob.indexOf('/')>-1 ? _dob.split('/') : _dob.split('-');
$('#Month').val(_adob[0]);
$('#Day').val(_adob[1]);

Indirectly

You really don't need to check that the string contains that... Using a regular expression, you can split on a -, /, or . by building a character set:

var _dob = '4.10';
var _aodb = _dob.split(new RegExp('[-/.]'));
