Question

I have a javascript object like this

var obj={
    a:{x: "someValue", y:"anotherValue"},
    b:{x: "bValue", y:"anotherbValue"}
};

and I am trying to reference it like this

function(some_value){
    alert("some_value is " + some_value + " with type " + typeof some_value);
    // prints  some_value is a  with type  string 
    var t;
    t=obj[some_value]["x"];   // doesn't work   
    some_value="a";
    t=obj[some_value]["x"];  // this does work
    t=obj["a"]["x"];     // and so does this
}

I would really like understand what is going on here . Ideally I’d like to reference my
object with the value passed to the function.
Thanks

I can only assume that your variable some_value must not contain the value a. It is possible that it has extra white space characters.
