.el-input { 
    		width: 30%;
    		margin-right: 20px;
    	}

new Vue({ 
    	el:'#page',//选择元素，通常都是id
    	data: function() { 
    		return {  //定义的变量
    			value1: '',
    			value2: '',
    			//注意：-----下面的javascript部分的代码放在这里
    		}
    	},
    })

    	disabledDate(time) { 
    		return time.getTime() > Date.now();
    	},
    	shortcuts: [{ 
    		text: '今天',
    		onClick(picker) { 
    			picker.$emit('pick', new Date());
    		}
    	}, { 
    		text: '昨天',
    		onClick(picker) { 
    			const date = new Date();
    			date.setTime(date.getTime() - 3600 * 1000 * 24);
    			picker.$emit('pick', date);
    		}
    	}, { 
    		text: '一周前',
    		onClick(picker) { 
    			const date = new Date();
    			date.setTime(date.getTime() - 3600 * 1000 * 24 * 7);
