Use callbacks to return data from an AJAX call, not return

function returnOptionList(optName, callback){
    $.post('getListTypes',{"key":optName},function(data) {

        if (data.ListNames == optName){

            for(var i=0; i<data.Values.length;i++){ 

                retval.push(data.Values[i]);
            }

        } 
        callback(retval)
    });       
}

And call:

returnOptionList(optName, data) {
    console.log(data); //your array
})

Please don't answer obvious duplicates. – SomeKittens Sep 23 '14 at 18:31 — SomeKittens, Sep 23 '14 at 18:31
