NaN从数组中删除。 Underscorejs Javascript

Question

我有一个数组Option Explicit Dim rng As Range Dim shiftRng As Range Sub ClearRow_Click() Dim currRow As Long Dim rng As Range Dim rngShift As Range currRow = ActiveCell.Row 'This is the full range of data If rng Is Nothing Then Set rng = Range("A5:J300") 'This gets the next n rows to the last row of your range If rngShift Is Nothing Then Set rngShift = Range("A" & (ActiveCell.Row + 1) & ":J300") If currRow >= 5 And currRow <= 300 Then '# This copies ONLY column A and moves the values up one row ' This will leave intact all of the rest of the data in columns B:J, etc. ' This preserves formatting -- essentially it just moves the values rngShift.Columns(1).Offset(-1).Value = rngShift.Columns(1).Value '# Get rid of the value in the last row, since it's been shifted up Range("A300").ClearContents End If End Sub 。

如何删除＆＃34; NaN＆＃34;从数组？

请给我正确的方向。

Answer 1

此处不需要强调。

arr = arr.filter( (el) => !Number.isNaN( el ) );

Answer 2

拒绝NaN：

的元素

 _.reject(array, _.isNaN)

Answer 3

您可以使用compact

var arr = [15,34,595,NaN];
arr = _.compact(arr);

注意：每个文档compact也会删除Javascript认为的任何其他内容falsy

  

false，null，0，＆＃34;＆＃34;，undefined和NaN
