DataWeave 以交替顺序组合数组

Question

如果我有数组 [A,B,C] 和 [1,2,3] 我怎样才能将它们组合成[A,1,B,2,C,3]

Answer 1

假设两个数组具有相同的长度：

%dw 2.0
output application/json
var a1=["A","B","C"]
var a2=[1,2,3]
---
a1 flatMap [$, a2[$]]

输出：

[
  "A",
  1,
  "B",
  2,
  "C",
  3
]

Answer 2

您还可以使用 zip

DW

%dw 2.0
output application/json
var a1=["A","B","C"]
var a2=[1,2,3]
---
flatten(a1 zip a2)

输出

[
  "A",
  1,
  "B",
  2,
  "C",
  3
]
