getFullYear is not a function报错

一定是你的js中少了一句

var date = new Date(date)

// 时间转化
var time = value.detail
var date = new Date(time)
// console.log(date) //标准时间
var date = (date.getFullYear()) + "-" + (date.getMonth() + 1)
// (time.getDate()) + " " + (time.getHours()) + ":" + (time.getMinutes()) + ":" + (time.getSeconds());
// console.log(date) //拼接之后的时间
this.setData({
   
        start_time: date,
        show_time_picker: false
})
