I have following javascript code:

```
var oReg = new Object;
oReg.a = {size: 762, content: 0};
oReg.b = {size: 342, content: 0};
//...

for (var s in oReg) {
    oReg[s].set = function(i) {
        alert('#name of oReg item#: ' + i);
    }
}

```

Where is "#name of oReg item#" should be a, b etc  

I think it should be begin with `this`, but I cant make it out.
