获取两个日期之间的月份名称

问题描述

我必须有两个日期from和to.我想获取这两个日期之间的所有月份名称.

I have to two dates from and to. I want to get all of the month names between these two dates.

以下是我的代码

var monthNames = [ "January", "February", "March", "April", "May", "June",
        "July", "August", "September", "October", "November", "December" ];

function diff(from, to) {
    var datFrom = new Date('1 ' + from);
    var datTo = new Date('1 ' + to);
    var arr = monthNames.slice(datFrom.getMonth(), datTo.getMonth() + 1);
}

以上代码可用于以下输入

above code works for following inputs

diff('September 2013', 'December 2013');

但不适用于此

diff('September 2013', 'February 2014');

我如何使它工作?

var monthNames = [ "January", "February", "March", "April", "May", "June",
        "July", "August", "September", "October", "November", "December" ];

function diff(from, to) {
    var arr = [];
    var datFrom = new Date('1 ' + from);
    var datTo = new Date('1 ' + to);
    var fromYear =  datFrom.getFullYear();
    var toYear =  datTo.getFullYear();
    var diffYear = (12 * (toYear - fromYear)) + datTo.getMonth();

    for (var i = datFrom.getMonth(); i <= diffYear; i++) {
        arr.push(monthNames[i%12] + " " + Math.floor(fromYear+(i/12)));
    }        

    return arr;
}

console.log(diff('September 2013', 'March 2014'));
