如何从数组中删除元素-Javascript P5

Question

这是我向数组添加元素的方法

assets.push(house_location + " " + "Cost" + " " + cost + " " + "Downpay"+ " " + downpay)

现在，我正在寻找一种方法，从数组中删除相同的特定元素。有人知道这个代码吗？所以基本上，与array.prush 相反

Answer 1

您要查找的是拼接方法。

Answer 2

如果你想删除你推送的最后一个项目，请使用assets.pop((。如果你想像你说的那样删除那个项目，你可以这样做：

assets.filter(d => d !== house_location + " " + "Cost" + " " + cost + " " + "Downpay"+ " " + downpay)

Answer 3

我猜您正在寻找这些方法。

Array.shift() // Removes the first item from an array, and then returns the item removed.
Array.pop() // Removes the last item from an array, and then returns the item removed.
Array.splice() // I really can't be bothered to explain this one, so look at the link below.

拼接方法。
