此列表有许多重复的行。我想删除所有重复的行。
对象可以有更多的10种性质也，所以检查每个属性是不是解决办法。另外，无论我上网的方式是1维阵列还是删除特定属性的重复。 我怎样才能保持一个包含所有行唯一一个列表？
我能想到的，是比较JSON对象的字符串化版本。像这样：'JSON.stringify（obj1）=== JSON.stringify（obj2）'。我猜想这个速度足够快，但元素属性的顺序很重要。这是一个问题吗？ – Scalpweb
没有订单不是问题。但即使我将每一行与所有其他行进行比较，这个过程是不是会太慢？随着列表大小的增加，复杂度将增加。 –
“善良的用户”的答案正是我想到的。 JSON.stringify过程是比较JS中2个对象的最快方法。我会说你必须制定一些基准来检查它是否足够快，但它应该没问题。 – Scalpweb
