Picker选择器，多级（3级以上）联动时，怎么默认选中指定对象？

2级联动我是会的 比如 ：picker.pickers[1].setSelectedIndex(1); 3级联动怎么写呢？

如果是3级联动，插件载入时岂不是不能自定义哪那一项被选中？

var cityPicker3 = new $.PopPicker({

layer: 3

});

cityPicker3.setData(cityData);

cityPicker3.setSelectedItems = function(items) {

var self = this;

//items = ["110000","110101","110108"];

        for (var i in self.pickers) {  

            var picker = self.pickers[i];  

            for(var j = 0;j<items.length;j++){  

                picker.setSelectedValue(items[j],"");  

            }  

            //console.log(i);  

        }  

    }  

var showCityPickerButton = doc.getElementById('showCityPicker');

var cityResult = doc.getElementById('cityResult');

showCityPickerButton.addEventListener('tap', function(event) {

cityPicker3.setSelectedItems(["110000","110101","110108"]);

cityPicker.hide(function(items) {

cityResult.innerText = "你选择的城市是:" + items[0].text + " " + items[1].text;

//返回 false 可以阻止选择框的关闭

//return false;

});

}, false);
