为什么Javascript数组是错误的？

Question

我有两个日志：

console.log(res.shared);
console.log(res.shared[0]);

唯一的问题是，完整数组日志的第0个元素与同一个数组的第二行上记录的第0个元素不同！如结果所示：

我称之为“回家Javascript！你喝醉了！”

编辑： 文本按@Zerkms的要求进行了字符串化并且是 - 它们与预期的一样，并且由PHP传递。但是，字符串化和非字符串化版本在同一个console.log中是不同的：

console.log(res.shared, JSON.stringify(res.shared));

编辑2：如果我再次在第556行之后输出完整的内容，结果与第555行相同。

编辑3：如果我只输出元素，则字符串化和非字符串化版本都是相同的：

console.log(res.shared[0], JSON.stringify(res.shared[0]));

Answer 1

控制台本身在日志时显示对象不的状态，但在展开时显示，即在您点击时它显示了内在的内容。

因此，完整数组以及您在控制台中看到的第一个元素不是日志时的状态（在那里，只记住对象的引用），但它显示了当时的状态点击它。在点击完整数组和点击元素之间有足够的时间来改变它。
