專案開發中,使用vue實現tab頁籤切換功能。具體例項如下:
(1)首先定義子元件,如下圖:
以select01.vue為例,子元件的原始碼如下:
- <template>
- <div slot='select01'>{{msg}}</div>
- </template>
- <script>
- export default {
- data(){
- return{
- msg:"select01"
- }
- }
- }
- </script>
- <style lang="scss">
- </style>
- <template>
- <div id="app">
- <div class="radio-wrap">
- <div class="radio-group" v-model="tabView">
- <span v-for="(tab ,index) in tabs" :class="{cur:iscur==index}" @click="iscur=index,tabChange('select' + (index + 1))">{{tab.name}}</span>
- </div>
- <div style="margin:10px 0;"></div>
- <keep-alive>
- <component v-bind:is="tabView"></component>
- </keep-alive>
- </div>
- </div>
- </template>
- <script>
- import select1 from './components/select01.vue';
- import select2 from './components/select02.vue';
- import select3 from './components/select03.vue';
- export default {
- name: 'app',
- data () {
- return {
- tabView: 'select1',
- tabs: [{name: "選項一"}, {name: "選項二"} ,{name: "選項三"}],
- iscur: 0
- }
- },
- components: {
- select1,
- select2,
- select3
- },
- methods: {
- tabChange:function(tab){
- this.tabView = tab;
- }
- }
- }
- </script>
- <style>
- .radio-group{font-size:0;height: 26px;line-height:26px;}
- .radio-group>span{cursor:pointer;display:inline-block;font-size:16px;text-align:center;width:100px;}
- .cur{color:#fff;background-color: #20a0ff;}
- </style>
