Question

Weird problem here, I’m trying to use a global function to update my settings object, example:

    var Settings = new Object;
    Settings.savepos = 'true';

    function UpdateSetting(obj,value){
        eval("Settings.obj = value");
        alert(Settings.savepos);
    }

The obj is the key of the object, meaning if I call the function with

UpdateSetting('savepos','false')

the alert will always just give me true, how do I convert that eval or any alternative so it will update settings object’s key with the value?

You should be able to use array notation on the object. Underneath it’s just a keyed hash.

Try:

Settings[obj] = value;

I’d also suggest passing values as they are, i.e. string, int, etc:

UpdateSetting('key_name', false);
