微信小程序如何处理页面缓存

微信小程序处理页面缓存的方法：

根据当前时间作为判断依据，缓存数据，代码：

Page({
 data: {
 },
 onLoad: function () {
//this.getNowTime()
if(wx.getStorageSync("loaction_time")==this.getNowTime()){
 //读取缓存
 console.log("缓存地址");
var datevalue=wx.getStorageSync("loaction");
console.log(datevalue)
}else{
 wx.removeStorageSync("loaction");
 //请求地址
 console.log("请求地址");
 var loactionname="bs";
 wx.setStorageSync("loaction",loactionname);
 wx.setStorageSync("loaction_time",this.getNowTime());
 var datevalue=wx.getStorageSync("loaction");
 console.log(datevalue)
}
 },getNowTime: function() {
var now = new Date();
var year = now.getFullYear();
var month = now.getMonth() + 1;
var day = now.getDate();
if(month < 10) {
 month = '0' + month;
};
if(day < 10) {
 day = '0' + day;
};
// 如果需要时分秒，就放开
var h = now.getHours();
var m = now.getMinutes();
var s = now.getSeconds();
//var formatDate = year + '-' + month + '-' + day + ' ' + h + ':' + m + ':' + s;
var formatDate = year + '-' + month + '-' + day;
//console.log('当前时间',formatDate)
return formatDate;
 }
})
