根据日期筛选对象数组 属性

Question

我想根据当前月份显示对象 我的代码是

 for (let m of  this.monthEvent){
     m=new Date();            
         if(m.getMonth() === new Date().getMonth()){
           this.thisMonth=m;
   }
     return this.thisMonth;

我的数组是

[{title: "", date: "2018-03-29"},
 {title: "", date: "2018-04-13"},
 {title: "", date: "2018-04-12"},
 {title: "leave", date: "2018-04-11"}
 {title: "", date: "2018-04-16"}]

它显示 m.getTime 不是函数

我要显示当月事件

提前致谢

• 您可以使用函数filter获取特定事件。
• 使用此解构赋值获取事件的月份var [_, month] = e.date.split('-');

var array = [{    title: "a",    date: "2018-03-29"  },  {    title: "b",    date: "2018-04-13"  },  {    title: "c",    date: "2018-04-12"  },  {    title: "leave",    date: "2018-04-11"  },  {    title: "d",    date: "2018-04-16"  }],
    currentMonth = new Date().getMonth() + 1,
    events = array.filter(e => {
        var [_, month] = e.date.split('-'); // Or, var month = e.date.split('-')[1];
        return currentMonth === +month;
    });

console.log(events);

.as-console-wrapper { max-height: 100% !important; top: 0; }
