=
ref
('foo')
const
item2
=
ref
(0)
const
item3
=
ref
({
prop
: 'val' })
const
list
= [
item1
,
item2
,
item3
]
const
result
=
useArrayJoin
(
list
)
// result.value: foo,0,[object Object]
item1
.
value
= 'bar'
// result.value: bar,0,[object Object]

与反应式数组一起使用

¥Use with reactive array

ts
import { 
useArrayJoin
} from '@vueuse/core'
const
list
=
ref
(['string', 0, {
prop
: 'val' }, false, [1], [[2]], null,
undefined
, []])
const
result
=
useArrayJoin
(
list
)
// result.value: string,0,[object Object],false,1,2,,,
list
.
value
.
push
(true)
// result.value: string,0,[object Object],false,1,2,,,,true
list
.
value
= [null, 'string',
undefined
]
// result.value: ,string,

与反应式分离器一起使用

¥Use with reactive separator

ts
import { 
useArrayJoin
} from '@vueuse/core'
const
list
=
ref
(['string', 0, {
prop
: 'val' }])
const
separator
=
ref
()
const
result
=
useArrayJoin
(
list
,
separator
)
// result.value: string,0,[object Object]
separator
.
value
= ''
// result.value: string0[object Object]
separator
.
value
= '--'
