1、创建一个dateTime.wxs文件，放在公共文件夹下，内容代码如下：
var formatNumber = function (n) {
n = n.toString()
return n[1] ? n : ‘0‘ + n
}
var regYear = getRegExp("(y+)", "i");
// 自定义的时间过滤器，下面parseInt(timestamp) * 1000主要是这里使用的s，如果是ms。去掉*1000即可
var dateFormat = function (timestamp, format) { if (!format) { format = "yyyy-MM-dd hh:mm:ss"; } timestamp = parseInt(timestamp) * 1000;
var realDate = getDate(timestamp);
function timeFormat(num) {
return num < 10 ? ‘0‘ + num : num;
}
var date = [
["M+", timeFormat(realDate.getMonth() + 1)],
["d+", timeFormat(realDate.getDate())],
["h+", timeFormat(realDate.getHours())],
["m+", timeFormat(realDate.getMinutes())],
["s+", timeFormat(realDate.getSeconds())],
["q+", Math.floor((realDate.getMonth() + 3) / 3)],
["S+", realDate.getMilliseconds()],
];
var reg1 = regYear.exec(format);
// console.log(reg1[0]);
if (reg1) {
format = format.replace(reg1[1], (realDate.getFullYear() + ‘‘).substring(4 - reg1[1].length));
}
for (var i = 0; i < date.length; i++) {
var k = date[i][0];
var v = date[i][1];
var reg2 = getRegExp("(" + k + ")").exec(format);
if (reg2) {
format = format.replace(reg2[1], reg2[1].length == 1
? v : ("00" + v).substring(("" + v).length));
}
}
return format;
}
module.exports = {
dateFormat: dateFormat
};
