Actually i am creating changepassword page. and this is my function of checking old password is match with the existing password or not. And that password is stored in MD5 in database so i want to first convert that password in MD5 and after that i can check that password.
Here is the code.

function fnIsValidOldPassword()

{

var oldPassword = ;

var objUser = new Object();



objUser.UserID = <?php echo $_SESSION['UserId'] ?>;

$.ajax({

    type: POST,

    url: db.php?GetUser,

    data: {data:objUser},

    async:false,

    dataType:json,

    success: function(response)

    {

        if(response.IsError)

            alert(response.ErrorMessage);

        else

            oldPassword = response.Records[0].Password;

    },

    error:function(message)

    {

        alert(Error:  + message);

    }

});



if($.md5($(#txtOldPassword).val())) != oldPassword)

         ^^ //here it shows error. that md5 is not a function.

{

    $(#errorPassword)[0].innerHTML = Wrong Old Password.;

    $(#txtOldPassword).removeClass(successTextBox).addClass(errorTextBox);

    return false;

}



$(#txtOldPassword).removeClass(errorTextBox).addClass(successTextBox);

$(#errorPassword)[0].innerHTML = ;

return true;

}

md5 is not a function in jquery then how to convert the password in md5.
