微信小程序block應該如何使用

for (var i = 0; i < goodsList.length; i++) {
 var PublishDatetime = goodsList[i].PublishDatetime.replace(/([\d\-]+)T(\d+:\d+)\:.*/, "$1 $2");//將帶T的時間格式轉化掉.
 PublishDatetime = PublishDatetime.replace(/-/g, "/");// 將格式‘-'轉化為‘/'
//換算時間戳，計算得到與當前時間的差距
 var minute = 1000 * 60;
 var hour = minute * 60;
 var day = hour * 24;
 var halfamonth = day * 15;
 var month = day * 30;
 var now = new Date().getTime();
 var diffValue = now - new Date(PublishDatetime).getTime();
 //console.log("diffValue:" + diffValue);
 if (diffValue < 0) {
 return;
 }
 var monthC = diffValue / month;
 var weekC = diffValue / (7 * day);
 var dayC = diffValue / day;
 var hourC = diffValue / hour;
 var minC = diffValue / minute;
 if (monthC >= 1) {
 if (monthC <= 12)
 goodsList[i].PublishDatetime = "" + parseInt(monthC) + "月前";//將時間替換掉想要的數據
 else {
 goodsList[i].PublishDatetime = "" + parseInt(monthC / 12) + "年前";//將時間替換掉想要的數據
 }
 }
 else if (weekC >= 1) {
 goodsList[i].PublishDatetime = "" + parseInt(weekC) + "周前";//將時間替換掉想要的數據
 }
 else if (dayC >= 1) {
 goodsList[i].PublishDatetime = "" + parseInt(dayC) + "天前";//將時間替換掉想要的數據
 }
 else if (hourC >= 1) {
 goodsList[i].PublishDatetime = "" + parseInt(hourC) + "小時前";//將時間替換掉想要的數據
 }
 else if (minC >= 1) {
 goodsList[i].PublishDatetime = "" + parseInt(minC) + "分鐘前";//將時間替換掉想要的數據
 } else {
 goodsList[i].PublishDatetime = "剛剛";//將時間替換掉想要的數據
 }
 }
 //最后將轉化后的時間重新賦值給數據源
