本文通过一段实例代码给大家介绍了微信小程序日期选择器的实现思路，非常不错，具有一定的参考借鉴价值，需要的朋友参考下吧
/* JS代码部分 */
3 const date = new Date()
const years = []
const months = []
const days = []
const hours = []
const minutes = []
var thisMon = date.getMonth();
var thisDay = date.getDate();
for (let i = 2017; i <= date.getFullYear() + 1; i++) {
years.push(i)
}
for (let i = date.getMonth(); i <= 11; i++) {
var k = i;
if (0 <= i && i < 9) {
k = "0" + (i + 1);
} else {
k = (i + 1);
}
months.push(k)
}
if (0 <= thisMon && thisMon < 9) {
thisMon = "0" + (thisMon + 1);
} else {
thisMon = (thisMon + 1);
}
if (0 <= thisDay && thisDay < 10) {
thisDay = "0" + thisDay;
}
var totalDay = mGetDate(date.getFullYear(), thisMon);
for (let i = 1; i <= 31; i++) {
var k = i;
if (0 <= i && i < 10) {
k = "0" + i
}
days.push(k)
}
for (let i = 0; i <= 23; i++) {
var k = i;
if (0 <= i && i < 10) {
k = "0" + i
}
hours.push(k)
}
for (let i = 0; i <= 59; i++) {
var k = i;
if (0 <= i && i < 10) {
k = "0" + i
}
minutes.push(k)
}
function mGetDate(year, month) {
var d = new Date(year, month, 0);
return d.getDate();
}
Page({
data: {
years: years,
year: date.getFullYear(),
months: months,
month: thisMon,
days: days,
day: thisDay,
value: [1, thisMon - 1, thisDay - 1, 0, 0],
hours: hours,

minutes: minutes,
minute: "00",
},
bindChange: function (e) {
const val = e.detail.value
this.setData({

month: this.data.months[val[1]],
day: this.data.days[val[2]],

minute: this.data.minutes[val[4]],
})
var totalDay = mGetDate(this.data.year, this.data.month);
var changeDate = [];
for (let i = 1; i <= totalDay; i++) {
var k = i;
if (0 <= i && i < 10) {
k = "0" + i
}
changeDate.push(k)
}
this.setData({
days: changeDate
})
},
})
/* css代码部分 */

/* html代码部分 */

}
