在Node.js日期对象中设置日期将日期显示为其他值 [英] Setting date in nodejs date object shows date as different value

问题描述

当我使用以下语句设置日期对象时，nodejs中的输出显示不同。您能帮我理解为什么会这样吗？以及我需要如何传递才能打印正确的值。

When i'm setting up date object using the below statement the output showing different in nodejs. Can you please help me to understand why it is like this. And how i need to pass to print right value.

var date1= new Date(2017,01,01);
var date2= new Date(2017,01,31);
console.log("2017-01-01 is printed as ==>",date1);
console.log("2017-01-31 is printed as ==>",date2);

输出

2017-01-01打印为==> 2017-01-31T18：30：00.000Z

2017-01-01 is printed as ==> 2017-01-31T18:30:00.000Z

2017-01-31打印为==> 2017 -03-02T18：30：00.000Z

2017-01-31 is printed as ==> 2017-03-02T18:30:00.000Z

推荐答案

打印这样的日志

console.log（ 2017-01-01打印为==> + date1）;
console.log（ 2017-01-31打印为==> + date2）;
将为您提供预期的日志
这是因为使用逗号时，控制台日志将日期作为日期对象；使用 + 时，它将应用 object.toString（）迄今为止的对象。

Printing your logs like this
console.log("2017-01-01 is printed as ==>"+date1); console.log("2017-01-31 is printed as ==>"+date2); will give you your expected logs It is because console log will take date as object of date while using comma and while using + it will apply object.toString() to date object.
