mui日期选择器怎么用啊，有没有完整的demo看一下

在hbuilder中新建移动app --> 选择模板 Hello mui，可看到示例代码

(function($) {  
    var GetDateInfo = $.getDateInfo = $.Class.extend({  
        init: function(element, fun) {  
            var self = this;  
            if(element.nodeType) {  
                self.ele = element;  
                fun && (self.fun = fun);  
                self.EventInit();  
            } else {  
                throw new Error('传入的参数不是Element类型！');  
            }  
            return self;  
        },  
        //绑定事件  
        EventInit: function() {  
            var self = this,  
                selfEle = this.ele,  
                isBindingEvent = selfEle.hasAttribute("data-getDate-event"); //是否绑定点击事件  
            !isBindingEvent && selfEle.addEventListener("tap", function() {  
                self.getDate()  
            }), selfEle.setAttribute("data-getDate-event", true); //绑定点击事件  
            !selfEle.hasAttribute("readonly") && selfEle.tagName == 'INPUT' && selfEle.setAttribute("readonly", "readonly"); //如果是INPUT添加禁用状态
