检查数组中是否包含除null之外的其他内容?
问题描述:
我有一个很可能总是这样的数组:
I have an array that will most likely always look like:
[null, null, null, null, null]
有时这个数组可能会改为:
sometimes this array might change to something like:
["helloworld", null, null, null, null]
我知道我可以使用for循环,但有没有办法使用 indexOf
来检查数组中的某些内容是否等于null。
I know I could use a for loop for this but is there a way to use indexOf
to check if something in an array that is not equal to null.
我正在寻找类似的东西:
I am looking for something like:
var index = indexof(!null);
