如何把_Cross交叉的值变数组形式显示

var crss = []            //存储 交叉死叉的值
    var records = _C(exchange.GetRecords,PERIOD_M30);
    var bar = records[records.length -1]
    var strsi = talib.STOCHRSI(records, 14, 14, 3, 3)  //获取StochRSI指标数据
        if (strsi) {
        var stoc = strsi[0]
        var mast = strsi[1]
        var cross = _Cross(stoc,mast)
        }
    if (bar.Time > mtb) {
        crss.push(cross)
    }
    Log(crss)

问题是我添加索引到crss，不管怎么弄，都只显示一个值 我想把cross变为数组形式显示，那位大佬帮帮忙看一下
