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;
}
})
