此列表有許多重複的行。我想刪除所有重複的行。
對象可以有更多的10種性質也，所以檢查每個屬性是不是解決辦法。另外，無論我上網的方式是1維陣列還是刪除特定屬性的重複。 我怎樣才能保持一個包含所有行唯一一個列表？
我能想到的，是比較JSON對象的字符串化版本。像這樣：'JSON.stringify（obj1）=== JSON.stringify（obj2）'。我猜想這個速度足夠快，但元素屬性的順序很重要。這是一個問題嗎？ – Scalpweb
沒有訂單不是問題。但即使我將每一行與所有其他行進行比較，這個過程是不是會太慢？隨着列表大小的增加，複雜度將增加。 –
「善良的用戶」的答案正是我想到的。 JSON.stringify過程是比較JS中2個對象的最快方法。我會說你必須制定一些基準來檢查它是否足夠快，但它應該沒問題。 – Scalpweb
