use the clientID property

document.getElementByID('<%=txtQuantity.ClientID %>')

More information here

you can also use find

Quoted from the above link:

Additionaly the ClientID is used in
ASP.NET Ajax as the unique identifier
of client-side controls. Thus the
following JavaScript statement is
commonly used:

var control = $find(<%=
MyControl1.ClientID %>);
