Jquery - How do you pass a variable into a function to use?

I am stumped by a problem which i'd assume is a common Jquery occurence, but i've no idea how to fix!

I have 5 variables -

 var pubtimed 
 var toolstimed 
 var newstimed 
 var mylinkstimed 
 var partnerstimed 

Which are used to store on and off states.

I then have a script that checks cookies for recent states and updates the variables accordingly, then forwards the details onto a render function -

var map = {
    'pub': $.cookie('nwphportal_tabExpPub'),
    'tools': $.cookie('nwphportal_tabExpTools'),
    'news': $.cookie('nwphportal_tabExpNews'),
    'mylinks': $.cookie('nwphportal_tabExpLinks'),
    'partners': $.cookie('nwphportal_tabExpPartners')
}

$.each(map, function (key, value) {
    if (value != null) {
        var varname = key + 'timed';
        varname = value;
        renderScrn(varname)
    } else {
        var varname = key + 'timed';
        varname = "1"
        renderScrn(varname)
    }
});

The problem I have is that I want the variable varname to be trea开发者_JAVA技巧ted as each of the 5 variables above (e.g. key plus timed = pubtimed). But this doesnt happen and I just get an error. I could just place a list of if statements to fix this, but wondered if there were a better solution?

Please help if you can!

Cheers for your time. Paul

I would go for namespacing, encapsulating the related data into one object:

var timed = {};

$.each(map, function (key, value) {

    if (value != null) {
        timed[key] = value;
        renderScrn(varname);
    }

    else {
        timed[key] = 1;
        renderScrn(varname);
    }
});​

So you can call them timed.partners, timed.pub, and so on...

If they're global variables, you can do this:

window[key + 'timed'] = value;

If they're not global (though they look so from what you posted), then you'll have to keep them in a container object, kind-of like your "map":

var container = {
  pubtimed: null,
  // ...
};

// ...

    container[key + 'timed'] = value;

edit — as @galambalazs wrote in his answer, it'd be better to avoid doing this. If you set up a container, just use the keys directly.
