Get Link Value From Object Literal, Onchange--javascript/html Select

I know how to operate this menu with a switch case routine, but I want to change my switch case to an object literal. Part A knows how to get the onchange value and open a window.

Solution 1:

This should make it dynamic.

functionvaluu() {
   ddd = document.getElementById("sed").value;
   window.open(foo(ddd), '_self');
}

You can do all this in one function like,

document.getElementById('sed').addEventListener ('change', function(e){
   var lynk = {
    'default': (''),
    'next': ('nextly.html'),
    'prev': ('previous.html'),
    'gimme': ('http://patreon.com/bearly'),
    'home': ('index.html')
   };
   window.open(lynk[e.target.value]);
});
