当执行上面的代码时，我收到以下错误，因为第一个循环的变量没有传递给第二个循环。
VM1172:301 Uncaught TypeError: Cannot read property 'products' of undefined(…)
'var jj =（data.sites）;'然后'data.sites [jj] .products'。看起来等于'data.sites [data.sites] .products'。 – Gavin
是的，你需要做'var ee = jj [key] .products;'或'var ee = data.sites [key] .products;'而不是'var ee =（data.sites [jj] .products）; '它工作得很好。 – Danmoreng
@ user2415266解决了这个问题。 @Gavin我也使用你的建议，并增加了另一个变量，以不使用相等的变量。谢谢 – therealdeal
