Trying to make a variable that is being changed dynamically in a private scope global

I think I got the Title right but here is what I want to do

        $(document).ready(function(){
        var oVars = {};
        var withones;
         etc //didnt work in what of my attempts to declare variables here so didnt cont.
        $('.checkboxes :checkbox').click(function(){
            var $this = $(this);
            if($(this).is(':checked')){


                    oVars[this.id] = true;
                    console.log( oVars)
                }
                if(!$this.is(':checked')){
                    oVars[this.id] = false;
                    console.log( oVars)
                }

at this point it is to my understanding that the oVars is like

               oVars{
                    withones : true,
                    withoutOnes : false, //if unchecked
                    dispReg :true //if checked
                }

I see the values of the properties change when I check the boxes

I want to be able to do something like this (globally):

               var withOnes = oVars['withones'];
                var withoutOnes = oVars['withoutOnes'];
                etc;

I want to declare these variables globally and I want their values to change according to true or false because that is what is being assigned in the if $(this).is(':checked') to demonstrate which one is checked. The reason why I want to do this is that i want to make a function where the argument is the updated value.

});

I would make a code like below somewhere else in the code

if(withOnes){ // I want withOnes to be true if checked false if unchecked
            process code if true
        }

I tried to do something like below. please help me figure out how to change these variables value so I could use the variable other places in the code

       if(withones = true){
            console.log("withones checked")
        }
        if(withones = false){
            console.log("withones unchecked")
        }

but only "withones checked" was displayed every time the checkbox was changes.

});
