响应式的 Array.join

用法

与多个 ref 组成的数组一起使用

import { useArrayJoin
 } from '@vueuse/core'

const item1
 = 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]

与响应式数组一起使用

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,

与响应式分隔符一起使用

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
 = '--'
// result.value: string--0--[object Object]
