                });
        };
    }
    $Core.DicCache = new _cache();
})(window, jQuery);

 

tempitem = cache[i] = cache[i] || {};初始化对象

$.extend({}, cache[dicCode]);获取数组中的对象

    //初始化字典数据
    $Core.DicCache.initDictionary("customerType,,yesno", function () {
        debugger;
    	$("#customerType").combobox({
            data: $Core.DicCache.get("customerType").originalData
    });

$Core.DicCache.get("devapplyState")[approveState]

 

 

 

 

必须要初始化new实例才能调用

实例化后通过全局window调用

 

后台实现：

	public AssembleJSON getDicByCodes(@PathVariable String dictCodes) {
