Redirecting to the root directory with JavaScript in Asp.Net

I have the following problem: I execute my application and start on the default.aspx page, I execute the following function from a button

function RedirectPage() { location.href = ../View/otherpage.aspx;}

Now I need to return to default.aspx and execute this function but it does not work ... what am I doing wrong?

function RedirectPage() { location.href = ../default.aspx;}
