JavaScript处理日期显示格式

• 在页面中，尤其是是评论这样功能，常常处理时间显示月，周，今天。

export const  getTimer = (stringTime)=>{
    if (!stringTime) return
    var minute = 1000 * 60;
    var hour = minute * 60;
    var day = hour * 24;
    var week = day * 7;
    var month = day * 30;
    let timer = stringTime.replace(/-/g,"/")
    var time1 = new Date().getTime();//当前的时间戳
    var time2 = Date.parse(new Date(timer));//指定时间的时间戳
    var time = time1 - time2;
    var result = null;
    if (time < 0) {
        alert("设置的时间不能早于当前时间！");
    } else if (time / month >= 1) {
        result = parseInt(time / month) + "月前";
    } else if (time / week >= 1) {
        result = parseInt(time / week) + "周前";
    } else if (time / day >= 1) {
        result =  parseInt(time / day) + "天前";
    } else if (time / hour >= 1) {
        result = parseInt(time / hour) + "小时前";
    } else if (time / minute >= 1) {
        result = parseInt(time / minute) + "分钟前";
    } else {
        result = "刚刚发布！";
    }
    return result;
}

• 直接在页面引入方法调用就行
