vuejs2 - 在 V-Data-Table 的全选 [VUETIFY] 中排除禁用的项目

Question

我有 v-data-table带有禁用项并希望在触发 select-all 时将其排除在 header.data-table-select投币口。也适用 :readonly但还是会被检查。

<template v-slot:item.data-table-select="{ item, isSelected, select }">
   <v-simple-checkbox
     :value="isSelected"
     :readonly="item.name == 'Frozen Yogurt'"
     :disabled="item.name == 'Frozen Yogurt'"
     @input="select($event)"
   ></v-simple-checkbox>
</template>

还看了docs并找到了这个 header.data-table-select slot 但只给了我这个选项:

{
  props: {
    value: boolean
    indeterminate: boolean
  },
  on: {
    input: (value: boolean) => void
  }
}

有没有办法处理 v-data-table 中选定的项目？ ?

Answer 1

可以从数据表中的全选中删除禁用的项目

我已经 在项目数组 中添加了一个新键“禁用”

Here is the working codepen: https://codepen.io/chansv/pen/mdJMvJr?editors=1010

<div id="app">
  <v-app id="inspire">
    <v-data-table
      v-model="selected"
      :headers="headers"
      :items="desserts"
      item-key="name"
      show-select
      class="elevation-1"
      @toggle-select-all="selectAllToggle"
    >
      <template v-slot:item.data-table-select="{ item, isSelected, select }">
