方法超级简单，把时间格式化一下就好了，直接奉上代码

function transDate() {

var $time =document.getElementById("share-time");

var date = $time.innerHTML.trim();

var tt = new Date(parseInt(date));

var days = parseInt((new Date().getTime() - date) / 86400000);

var today = new Date().getDate();

var year = tt.getFullYear();

var mouth = tt.getMonth() + 1;

var day = tt.getDate();

var time = tt.getHours() < 10 ? "0" + tt.getHours() : tt.getHours();

var min = tt.getMinutes() < 10 ? "0" + tt.getMinutes() : tt.getMinutes();

var result, offset;

offset = Math.abs(today - day);

if (days < 4&&offset<4) {

if (offset === 0) {

result = "今天" + time + ":" + min;

} else if (offset === 1) {

result = "昨天" + time + ":" + min;

} else if (offset === 2) {

result = "前天" + time + ":" + min;

}

} else {

result = year + "-" + mouth + "-" + day + " " + time + ":" + min;

}

$time.innerHTML = result;

}

transDate();
