Question

week变量只是用json构建的多维数组的表示形式，我使用相同的方法（不是多维的）使用其他数组，它们可以正常工作。

数组而不是0、1、2、3，...具有'monday'，'thursday'，...具有第一级的名称。

Object.keys

给出一个错误，指出长度和移位是没有功能的。

我怀疑您想这样做：

但是您的json对象是错误的（从语法上和结构上）。

使用jQuery解决

$.each(week, function(key, val){
    console.log(key);
	for (var i = 0; i < val.length; i++){
      console.log(val);
	}
});

通过带有标题的多维数组以获取信息
