用 javascript 计算日期时间（以天为单位）

Question

I have a date in datetime and I need to calculate it with the current date in javascript to check if 7 days have passed.

 var created_at = 2021-05-20; //return 2021-05-20 14:00:00 var data = new Date(); var dataAtual = data.getFullYear() + "-" + ("0" + (data.getMonth() + 1)).substr(-2) + "-" + ("0" + data.getDate()).substr(-2); var result = data - created_at; if(result < 7){ var create_date = true; console.log(true); } else { var created_date = false; console.log(false); }

Answer 1

Can you try the below code

var date1 = new Date('2021-05-20 14:00:00')
var date2 = new Date()
var resulu = date2.getDate() - date1.getDate()
if(result < 7){
  var create_date = true;
  console.log(true);
} else {
  var created_date = false;
  console.log(false);
}

Get the difference of dates in milliseconds and convert into days.

 const old_date = new Date('2021-05-20'); const today = new Date(); const diff_days = (today - old_date) / 24 * 60 * 60 * 1000; if (diff_days < 7) { console.log('older than a week'); } else { console.log('in last week'); }
