js 字符串中包含逗号和分号分析成数组

var str = "117.39755436808615, 34.59211450864094;117.39783481906638, 34.59185738594207;117.39825396841732, 34.59151467824745;117.39895365857903, 34.59099990825333;117.39975863014654, 34.59003217058297;117.40108929009845, 34.58869213304237;"

    var newArr = []
    var reg = /([^,;；]+)[,\s]+([^,;；]*)/g;
    while(reg.exec(str)){
        console.log( RegExp.$1 + "," + RegExp.$2);
        var aa = [Number(RegExp.$1),Number(RegExp.$2)]
        newArr.push(aa)
    }
    console.log('aaa==>>',newArr)
