在JavaScript中添加一个月到一个日期 [英] Add One Month to a Date in JavaScript

问题描述

我有一个输入字段，需要使用JavaScript Date对象增加一个月。以下是我在增加月份所做的努力的一个例子。这个问题似乎是，它将显示0为1月，不会增加一年。

I have an input field that needs to be incremented by one month using the JavaScript Date object. Below is an example of an effort I have made in incrementing the month. The issue with this seems to be that it will display 0 as January and does not increment the year.

nDate.setDate(nDate.getDate());
inputBox1.value = (nDate.getMonth() + 1) + "/" + (nDate.getDate()) + "/" +  (nDate.getFullYear());

推荐答案

// assumes document.form1.textbox1.value is a parseable date
var d = new Date( document.form1.textbox1.value );
d.setMonth( d.getMonth( ) + 1 );
document.form1.textbox1.value = ( d.getMonth( ) + 1 ) + '/' + d.getDate( ) + '/' + d.getFullYear( );

设置月份应该是范围证明，如这里。

Set month supposed to be range proof, as described here.
