我正在尝试修改https://vuetifyjs.com/en/components/autocompletes#example-作用域插槽，允许任意内容与芯片之间的任何自动完成项目不匹配(因此用户可以在类似于slack和facebook的消息中标记其他用户(
例如，用户可以键入"Sandra"，然后选择"Sandra adams"，然后键入"foo"，然后输入另一个空格，开始键入"John"，autcomplete将再次弹出，允许用户选择"John Smith"。
我已经浏览了文档中的所有属性，似乎没有支持这个内置属性。
当显示自动完成选项时，我尝试使用自定义筛选来忽略消息中不相关的部分，但当自动完成失去焦点时，它似乎会删除非芯片内容，而且我看不到允许我阻止这种行为的属性。
不确定autcomplete是要使用的东西，还是我最好破解组合框来满足这个要求，因为这个样本似乎更接近我想要做的https://vuetifyjs.com/en/components/combobox#example-没有数据，但我相信我失去了automcomplete附带的ajax功能。
您可以通过将自动完成的异步搜索与组合框相结合来实现这一点。
例如：
new Vue({
el: '#app',
data: () => ({
activator: null,
attach: null,
colors: ['green', 'purple', 'indigo', 'cyan', 'teal', 'orange'],
editing: null,
descriptionLimit: 60,
index: -1,
nonce: 1,
menu: false,
count: 0,
model: [],
x: 0,
search: null,
entries: [],
y: 0
}),
computed: {
fields () {
if (!this.model) return []
return Object.keys(this.model).map(key => {
return {
key,
value: this.model[key] || 'n/a'
}
})
},
items () {
return this.entries.map(entry => {
const Description = entry.Description.length > this.descriptionLimit
? entry.Description.slice(0, this.descriptionLimit) + '...'
: entry.Description
return Object.assign({}, entry, { Description })
})
}
},
watch: {
search (val, prev) {
// Lazily load input items
axios.get('https://api.publicapis.org/entries')
.then(res => {
console.log(res.data)
const { count, entries } = res.data
this.count = count
this.entries = entries
})
.catch(err => {
console.log(err)
})
.finally(() => (this.isLoading = false))
/*if (val.length === prev.length) return
this.model = val.map(v => {
if (typeof v === 'string') {
v = {
text: v,
color: this.colors[this.nonce - 1]
}
this.items.push(v)
this.nonce++
}
return v
})*/
},
model (val, prev) {
if (val.length === prev.length) return
this.model = val.map(v => {
if (typeof v === 'string') {
v = {
Description: v
}
this.items.push(v)
this.nonce++
}
return v
})
}
},
methods: {
edit (index, item) {
if (!this.editing) {
this.editing = item
this.index = index
} else {
this.editing = null
this.index = -1
}
},
filter (item, queryText, itemText) {
const hasValue = val => val != null ? val : ''
const text = hasValue(itemText)
const query = hasValue(queryText)
return text.toString()

将来可能会尝试将其封装为一个小的NPM包，以供任何想要以一种声明性的方式为vue使用tribute.js的人使用，这种方式比vue致敬允许的方式更灵活，但现在这里是我的概念验证
