Question

I have a function which you can pass an object to. I then need all the vars within this object to become local variables. For instance

function ping(){
    alert(riff); //'raff'
}

ping({
    riff: 'raff'
});

The only way I can think to do it is looping the object and setting them one by one but that seems clunky. Any alternatives?

Edit: the return was to show what that variable would be like. The main thing I don’t want is to have to go through another object to get to the data. I want the structure to be

 function.riff = 'raff' 

rather than

 function.settings.riff = 'raff'

Answer 1

function ping(){
    for(var key in arguments[0]){
        this[key] = arguments[0][key];
    }
}

This currently the best answer I can come up with… any advances on this?

Note how the vars are added directly into the function rather than through an object in the function.

This is because I want to be able to overwrite private function vars with this object before they are used.
