JavaScript获取当前月份的前12个月，获取最近的12个月

  var dataArr = [];
    var data = new Date();
    var year = data.getFullYear();
    data.setMonth(data.getMonth()+1, 1)//获取到当前月份,设置月份
    for (var i = 0; i < 12; i++) {
        data.setMonth(data.getMonth() - 1);//每次循环一次 月份值减1
        var m = data.getMonth() + 1;
        m = m < 10 ? "0" + m : m;
        dataArr.push(data.getFullYear() + "-" + (m))
    }

    console.log(dataArr)
