JavaScript：将数组转换为无键或字符串的 object

Question

I have an array like [1,2,3,4,5] . I want to convert it to object like {1,2,3,4,5} or 1,2,3,4,5 .

I would be thankful if someone helps me.

Answer 1

for 1,2,3,4,5 , you just have to use .join()

 const arr = [1,2,3,4,5] console.log(arr.join())

Also, specifically for query parameters, in browser or Node, you could use URLSearchParams , which helps you define your query object

 const obj = { a: [1,2,3,4,5] } const searchParams = new URLSearchParams(obj).toString(); console.log(searchParams)
