弹出框是使用的artDialog，需要可以做扩展，以下代码供参考：

// 事件代理
_addEvent: function () {
    var resizeTimer,
that = this,
config = that.config,
isIE = 'CollectGarbage' in window,
DOM = that.DOM;
 
    // 窗口调节事件
    that._winResize = function () {
        resizeTimer && clearTimeout(resizeTimer);
        resizeTimer = setTimeout(function () {
            that._reset(isIE);
        }, 40);
    };
    _$window.bind('resize', that._winResize);
 
    // 监听点击
    DOM.wrap
.bind('click', function (event) {
    var target = event.target, callbackID;
 
    if (target.disabled) return false; // IE BUG
 
    if (target === DOM.close[0]) {
        that._click(config.cancelVal);
        return false;
    } else if (target === DOM.max[0]) {
        that.max();
    } else if (target === DOM.min[0]) {
        that.min();
    } else {
        callbackID = target[_expando + 'callback'];
        callbackID && that._click(callbackID);
    };
 
    that._ie6SelectFix();
})
.bind('mousedown', function () {
    that.zIndex();
});
},
