小程序实现微信朋友圈时间显示效果

 

小程序实现微信朋友圈时间显示效果:

1分钟前,2分钟前,···,59分钟前,1小时前,2小时前,···,23小时前,一天前,2天前,2019-06-21 等等...

 

相关代码如下:getTime() {    let start = '2019-6-21 22:41:00'    let nowTime = new Date()

    let oldTime = new Date(start)
    let diff = Math.floor((nowTime - oldTime)/1000/60)
    let time = start
    
    if(diff <= 59){
        time = diff + '分钟前'
    }else if(diff <= 60*24-1){
        time = Math.floor(diff / 60) + '小时前'
    }else if(diff <= 60*24*3-1){
        time = Math.floor(diff / 60 / 24) + '天前'
    }else{
        time = time.split(" ")[0]  
    }
    return time
}

 

实际开发过程中,会发现后台返回的数据不可能一直是 yyyy-mm-dd hh:ii:ss 格式的

也可能返回的是时间戳,这个时候会报  time.split 不是一个方法

 

解决方法:将时间戳或者 yyyy-mm-dd hh:ii:ss 格式 都通过js的Dete对象转换,代码如下:

getTime() {
    let start = '2019-6-21 22:41:00'
    let nowTime = new Date()
    let oldTime = new Date(start)
    let diff = Math.floor((nowTime - oldTime) / 1000 / 60)
    let time = start
    if (diff <= 59) {
        time = diff + '分钟前'
    } else if (diff <= 60 * 24 - 1) {
        time = Math.floor(diff / 60) + '小时前'
    } else if (diff <= 60 * 24 * 3 - 1) {
        time = Math.floor(diff / 60 / 24) + '天前'
    } else {
        // time = time.split(" ")[0]   // startTime格式:yyyy-mm-dd hh:ii:ss
        time = this.getNowFormatDate(time)
    }
    return time
}
getNowFormatDate(time) {
    let date = new Date(time);
    let seperator1 = "-";
    let year = date.getFullYear();
    let month = date.getMonth() + 1;
    let strDate = date.getDate();
    if (month >= 1 && month <= 9) {
        month = "0" + month;
    }
    if (strDate >= 0 && strDate <= 9) {
        strDate = "0" + strDate;
    }
    let currentdate = year + seperator1 + month + seperator1 + strDate;
    return currentdate;
}

 

开发中因为不确定后台传回的是什么样的格式,因此在刚开始添加全局替换

ios不支持 “yyyy-mm-dd”,那么就替换成 “yyyy/mm/dd”

let reg=new RegExp("-");
if(reg.test(startTime)){
    startTime = startTime.replace(/-/g, '/')
}
