如何获得记录今天和流星JS.I过去的7天记录我使用创建日期如何获得今天和过去7天记录流星JS？

var date = new Date();

我使用MongoDB的集合代码如下所示：

var today = new Date(); 
var dd = today.getDate(); 
var mm = today.getMonth()+1; //January is 0! 
var yyyy = today.getFullYear(); 
var start = new Date(""+yyyy+"-"+mm+"-"+dd+"T00:00:00.000Z"); 
var end = new Date(""+yyyy+"-"+mm+"-"+(dd+1)+"T00:00:00.000Z"); 
var fetchResult = Profile.find({created:{$gte: start, $lt: end}});

怎么办？

回答：

尝试从当前日期的时间戳减去天数：

var today = new Date(); 
var weekAgoDate = new Date(); 
weekAgoDate.setUTCDate(weekAgoDate.getDate() - 7); 
var fetchResult = Profile.find({created:{$gte: weekAgoDate, $lt: today}});

使用momentjs API是非常直观，更容易理解：

var today = moment(); 
var weekAgoDate = today.subtract("days", 7); // same as today.add("days", -7) 
var fetchResult = Profile.find({created:{$gte: weekAgoDate.toDate(), $lt: today.toDate()}});

注意：要获得Moment.js包装的本地Date对象，使用toDate()

回答：

请查看下面的代码片段

var today_date = new Date(frame_date()); 
var range_date = new Date(today_date); 
range_date.setDate(today_date.getDate() - 1); // for toady records 
Profile.find({ 'created': {$gte: range_date, $lte: today_date}}) 
range_date.setDate(today_date.getDate() - 7); // for last 7 days records 
Profile.find({ 'created': {$gte: range_date, $lte: today_date}})

功能frame_date定义这里 -

function frame_date() { 
    var time = require('time'); 
    var timestamp = new time.Date(); 
//  var timestamp = new Date(); 
    timestamp.setTimezone("Australia/Sydney"); //you can set timezone here 
    var getYear = timestamp.getFullYear(); 
    var getMnth = timestamp.getMonth(); 
    var getDate = timestamp.getDate(); 
    var gethours = timestamp.getHours(); 
    var getMins = timestamp.getMinutes(); 
    var getSecs = timestamp.getSeconds(); 
    var getMilisecs = timestamp.getMilliseconds(); 
    if (getDate < 10) { 
     getDate = "0" + getDate; 
    } 
    if (getMnth < 9) { 
     getMnth = parseInt(getMnth) + 1 
     getMnth = "0" + getMnth; 
    } else { 
     getMnth = getMnth + 1; 
    } 
    if (gethours < 10) { 
     gethours = "0" + gethours; 
    } 
    if (getMins < 10) { 
     getMins = "0" + getMins; 
    } 
    if (getSecs < 10) { 
     getSecs = "0" + getSecs; 
    } 
    var getMiliSecs = getMilisecs; 
    if (getMilisecs < 10) { 
     getMiliSecs = "0" + getMilisecs; 
    } else if (getMilisecs < 100) { 
     getMiliSecs = "00" + getMilisecs; 
    } else { 
     getMiliSecs = getMilisecs; 
    } 
    var final_framed_date = getYear + "-" + getMnth + "-" + getDate + " " + gethours + ":" + getMins + ":" + getSecs + "." + getMiliSecs; 
    return final_framed_date; 
}
