Mode

Introduction to the working modes of v-selectpage components

Selector mode

Regular dropdown selection mode

import { SelectPageList, SelectPageTable } from 'v-selectpage'

import { SelectPageList, SelectPageTable } from 'v-selectpage'

Core module mode

The core module is a list and table module with search and paging functionality, which can be used directly, placed in other containers, or combined with other components to greatly expand the forms and scenarios in which the functionality can be used

import { SelectPageListCore, SelectPageTableCore } from 'v-selectpage'

import { SelectPageListCore, SelectPageTableCore } from 'v-selectpage'

Examples

List view

vue

<template>
  <SelectPageList @fetch-data="fetchData" />
</template>

<script setup lang="ts">
import { SelectPageList } from 'v-selectpage'
import type { PageParameters, FetchDataCallback } from 'v-selectpage'

// local data list for example
const list = [
  { id: 1, name: 'Chicago Bulls', desc: '芝加哥公牛' },
  { id: 2, name: 'Cleveland Cavaliers', desc: '克里夫兰骑士' },
  { id: 3, name: 'Detroit Pistons', desc: '底特律活塞' },
  ...
]

function fetchData (data: PageParameters, callback: FetchDataCallback) {
  const { search, pageNumber, pageSize } = data

  const start = (pageNumber - 1) * pageSize
  const end = start + pageSize - 1
  // filter by search keyword
  const filtered = search
    ? list.filter(val => val.name.includes(search))
    : list

  callback(
    // get current page items
    filtered.filter((val, index) => index >= start && index <= end),
    filtered.length
  )
}
</script>

<template>
  <SelectPageList @fetch-data="fetchData" />
</template>

<script setup lang="ts">
import { SelectPageList } from 'v-selectpage'
import type { PageParameters, FetchDataCallback } from 'v-selectpage'

// local data list for example
const list = [
  { id: 1, name: 'Chicago Bulls', desc: '芝加哥公牛' },
  { id: 2, name: 'Cleveland Cavaliers', desc: '克里夫兰骑士' },
  { id: 3, name: 'Detroit Pistons', desc: '底特律活塞' },
  ...
]

function fetchData (data: PageParameters, callback: FetchDataCallback) {
  const { search, pageNumber, pageSize } = data

  const start = (pageNumber - 1) * pageSize
  const end = start + pageSize - 1
  // filter by search keyword
  const filtered = search
    ? list.filter(val => val.name.includes(search))
    : list

  callback(
    // get current page items
    filtered.filter((val, index) => index >= start && index <= end),
    filtered.length
  )
}
</script>

In the above example, local static data is used as an example, but in more cases we need to apply remote data for loading and query

function fetchData (data, callback) {
  const params = { ... }
  // get current page items from remote api
  axios.post('some-api-address', params).then(resp => {
    callback(resp.list, resp.count)
  })
}

function fetchData (data, callback) {
  const params = { ... }
  // get current page items from remote api
  axios.post('some-api-address', params).then(resp => {
    callback(resp.list, resp.count)
  })
}

Keyboard shortcuts

When the dropdown container is open and the input focus is in the search box, the following actions can be used for shortcut operations

up and down key to toggle the current highlighted item
left and right key to switch to the previous or next page
enter When a highlighted row exists, the data in that row will be selected
esc close dropdown container

Table view

vue

<template>
  <SelectPageTable
    :columns="teamColumns"
    @fetch-data="fetchData"
  />
</template>

<script setup lang="ts">
import { SelectPageTable } from 'v-selectpage'
import type {
  PageParameters, FetchDataCallback, SelectPageTableColumn
} from 'v-selectpage'

// local data list for example
const list = [
  { id: 1, name: 'Chicago Bulls', desc: '芝加哥公牛', abbr: 'CHI' },
  { id: 2, name: 'Cleveland Cavaliers', desc: '克里夫兰骑士', abbr: 'CLE' },
  { id: 3, name: 'Detroit Pistons', desc: '底特律活塞', abbr: 'DET' },
  ...
]
const teamColumns: SelectPageTableColumn[] = [
  { title: 'Id', data: 'id' },
  { title: 'Team name', data: row => `${row.abbr} - ${row.name}`, width: 250 },
  { title: 'Description', data: 'desc' }
]

function fetchData (data: PageParameters, callback: FetchDataCallback) {
  ...
}
</script>

<template>
  <SelectPageTable
    :columns="teamColumns"
    @fetch-data="fetchData"
  />
</template>

<script setup lang="ts">
import { SelectPageTable } from 'v-selectpage'
import type {
  PageParameters, FetchDataCallback, SelectPageTableColumn
} from 'v-selectpage'

// local data list for example
const list = [
  { id: 1, name: 'Chicago Bulls', desc: '芝加哥公牛', abbr: 'CHI' },
  { id: 2, name: 'Cleveland Cavaliers', desc: '克里夫兰骑士', abbr: 'CLE' },
  { id: 3, name: 'Detroit Pistons', desc: '底特律活塞', abbr: 'DET' },
  ...
]
const teamColumns: SelectPageTableColumn[] = [
  { title: 'Id', data: 'id' },
  { title: 'Team name', data: row => `${row.abbr} - ${row.name}`, width: 250 },
  { title: 'Description', data: 'desc' }
]

function fetchData (data: PageParameters, callback: FetchDataCallback) {
  ...
}
</script>

teamColumns defines the data columns in the table. The data attribute in the column model has the same function as labelProp, that is, you can specify a certain data column as the content field, or provide a function to render the content of the cell to make customizations

In the table view, labelProp is only used to specify the content of the selected item in the trigger object

  PageParameters, FetchDataCallback
} from 'v-selectpage'

function fetchData (data: PageParameters, callback: FetchDataCallback) { ... }
function fetchSelectedData (
  keys: SelectPageKey[],
  callback: FetchSelectedDataCallback
) {
  // get items model by keys when v-model is set to a non-empty value
  callback(list.filter(val => keys.includes(val.id)))
}
</script>

<template>
  <SelectPageList
    multiple
    v-model="selected"
    @fetch-data="fetchData"
    @fetch-selected-data="fetchSelectedData"
  />
</template>

const selected = ref<SelectPageKey[]>([1, 2, 4])

function fetchData (data: PageParameters, callback: FetchDataCallback) { ... }
function fetchSelectedData (

  callback: FetchSelectedDataCallback
) {
  // get items model by keys when v-model is set to a non-empty value
  callback(list.filter(val => keys.includes(val.id)))
}
</script>

v-model and fetch-selected-data

The above is an example of setting a default selected item. v-model is used in conjunction with the fetch-selected-data event. When one or more keys are set using v-model (the content of the key values should correspond to the data columns specified by keyProp), the component responds to the fetch-selected-data event to fetch the data corresponding to the key, while the selection of the item(s) through the interaction of the component does not trigger this event.

Limit the maximum number of selection

Set the max value to limit the maximum number of selections that can be made

columns

type TableColumn[]
default undefined

Tabular data column setting model

interface TableColumn {
  title: string           // title text

    :modelValue="selected"
    @update:modelValue="keys => selected = keys"
  />
</template>

fetch-data

Response data list fetching and content searching

`fetch-data`: (data: PageParameters, callback: FetchDataCallback) => void

interface PageParameters {
  search: string     // search keyword
  pageNumber: number // current page number
  pageSize: number   // the number of records per page
}
type FetchDataCallback = (

The response function submits the results of the data query to the component via the callback function based on the paging and search information provided by data

function fetchData (data, callback) {
  const params = { ... }
  search(params).then(resp => callback(resp.list, resp.count))
}

function fetchData (data, callback) {

API

Before using the component's API, you need to declare the ref attribute for the component, and use ref() to declare a reactive variable with the corresponding name to call the API method

vue

<script setup>
import { ref } from 'vue'
import { SelectPageListCore } from 'v-selectpage'

const selectPage = ref()
// call api
selectPage.value.removeAll()
</script>

<template>
  <SelectPageListCore ref="selectPage" />
</template>

<script setup>
import { ref } from 'vue'
import { SelectPageListCore } from 'v-selectpage'

const selectPage = ref()
// call api
selectPage.value.removeAll()
</script>

removeItem

Remove the selected state of the specified data

removeItem: (item: Record<string, unknown>) => void

removeItem: (item: Record<string, unknown>) => void

This API only work on Core module mode

removeAll: () => void

This API only work on Core module mode
