    var chartLabels = [];
    var d = new Date();
    for (var m_month = 0; m_month < 5; m_month++){
        chartLabels[m_month] = month[d.getMonth()];
            d.setMonth(d.getMonth()-1);
    }

它今天(4/1)工作,但它昨天没有用.如果你使用var d = new Date(2016,3,30)运行它,你将在结果中得到March两次.我上个月尝试了一段时间的声明,但它没有用.

    var d = new Date(2016, 03, 30);
    for (var m_month …
