面向对象 读取配置信息

function Rect(config) {

    // var this = new Object();
    for (var i  in config) {
        this[i] = config[i];
    }

    // return this;
}


// 共
React.prototype = {

    // 指回
    constructor:Rect;

    //  stroke.call(this,arguments);
    stroke:function(){
        console.log(this.key);
    }
}
