就是这个函数。大函数内嵌小函数。返回值还是个带冒号的东东。到底是怎么回事？究竟返回了个神马？



    function StringStore(strings) {
        function getText(id) {
            var text = strings[id];
            if (!text)
                return '';
            if (text[0] == '*')
                return text.substring(1);
            var extracted = extract(text);
            strings[id] = '*' + extracted;
            return extracted;
        }
        function extract(text) {
            var decoded = JXG.Util.Base64.decodeAsArray(text);
            var extracted = (new JXG.Util.Unzip(decoded)).unzip()[0][0];
            return JXG.Util.UTF8.decode(extracted);
        }
        function get(id) {
            if (id === null) return null;
            return getText(id);
        }
        return {get: get};
    }
