组件创建、组件注册方式

一、创建组件

1.在存放组件的目录下新建组件页面文件li-activity.vue文件,

<template name="li-activity">
    <view class="li-group">
        <view class="act-img-left">
            <image :src="list.image" class="img" mode=""></image>
            <view class="share-num-icon" v-if="list.scan">
                <text class="sha-num">{{list.scan}}</text>
                <text class="has-num">{{list.share}}</text>
            </view>
        </view>
        <view class="act-content-right">
            <text class="title">{{list.title}}</text>
            <text class="subtitle">{{list.subtitle}}</text>
            <view class="bottom-content">
                <text class="type">免费</text>
                <view class="button">
                    <view class="example tap-button" @tap="goExample(list.cates,list.id)">查看详情</view>
                    <view class="creat tap-button" @tap="goCreat(list.cates,list.id)">创建</view>
                </view>
            </view>
        </view>
    </view>
</template>

li-activity.vue 文件的组件相关配置:

<script>
    export default {
        name:'li-activity',
        props:{
            list:{
                type:Object,
                default:{}
            }
        },
        methods:{
            goExample:function(cate,id){
                uni.navigateTo({
                    url: '/pages/activity-detail/'+ cate +'/'+ cate +'?id='+id
                });
            },
            goCreat:function(cate,id){
                uni.navigateTo({
                    url:'/pages/activity-creat/'+ cate +'/'+ cate +'?id='+id
                })
            }
        }
        
    }
</script>

name为组件名称;props为相关动态控制的参数,在使用该组件时传递过来;methods为组件内绑定的相关事件

二、组件注册

2.1、全局组件注册

在main.js中引入该组件文件:

import liActivity from './pages/components/li-activity/li-activity.vue'

组件全局注册:

Vue.component('li-activity',liActivity);

然后便可以在其他文件中使用该组件,如在index.vue中使用组件:

<template>
    <view class="content">
        <li-activity v-for="(item,index) in actlist" :key="index" :list="item"></li-activity>
    </view>
</template>

<script>
    export default {
        data() {
            return {
                cate:'',
                cid:'',
                page:'1',
                actlist:[]
            };
        },
        onLoad(e) {
            this.getList(1)
        },
        methods:{
            getList:function(page){}
        }
    }
</script>

<style>
.content{
    width: 100%;
    padding-left: 3%;
    padding-right: 3%;
    box-sizing: border-box;
}
</style>

2.2、局部组件注册

直接在需要使用组件的页面进行注册组件,如在index.vue中使用组件:

在index.vue中引入组件文件:

import liActivity from '../../components/li-activity/li-activity.vue'

并在该页面进行组件注册:

components:{
    'li-activity':liActivity
},

然后便可以在其他文件中使用该组件,局部注册组件完整代码如下:

<template>
    <view class="content">
        <li-activity v-for="(item,index) in actlist" :key="index" :list="item"></li-activity>
    </view>
</template>

<script>
    import liActivity from '../../components/li-activity/li-activity.vue'
    export default {
        data() {
            return {
                cate:'',
                cid:'',
                page:'1',
                actlist:[]
            };
        },
        components:{
            'li-activity':liActivity
        },
        onLoad(e) {
            this.getList(1)
        },
        methods:{
            getList:function(page){}
        }
    }
</script>

<style>
.content{
    width: 100%;
    padding-left: 3%;
    padding-right: 3%;
    box-sizing: border-box;
}
</style>
