vue—封装组件（列表样式）

效果图：

 主要就是需要把写的vue前端页面中的每个数据抽离出来，方便后续的引用与修改

原来的vue代码：

<template>
    <view>
        <view class="index-list">
            <view class="index-list1">
                <view class="">
                    <image src="../../static/demo/userpic/12.jpg" mode="widthFix" lazy-load></image>
                    昵称
                </view>
                <view>
                    <view class="icon iconfont icon-zengjia"></view>关注
                </view>
            </view>
            <view class="index-list2">我是标题</view>
            <view class="index-list3">
                <!-- 图片 -->
                <image src="../../static/demo/datapic/11.jpg" mode="widthFix" lazy-load></image>
                <!-- 视频 -->
                <view class="icon iconfont icon-bofang index-list-play"></view>
                <view class="index-list-playInfo">
                    20W播放 2:47
                </view>
            </view>
            <view class="index-list4">
                <!-- 左边 -->
                <view>
                    <view>
                        <view class="icon iconfont icon-icon_xiaolian-mian"></view>10

                </view>
                <!-- 右边 -->
                <view>
                    <view>
                        <view class="icon iconfont icon-pinglun1"></view>10
                    </view>
                    <view>
                        <view class="icon iconfont icon-zhuanfa"></view>10
                    </view>
                </view>
            </view>
        </view>
    </view>
</template>

<script>
    export default {
        data() {
            return {
                title: 'Hello'
            }
        },
        onLoad() {

        },
        methods: {

        }
    }
</script>

<!-- uniapp在编译的时候会把子组件和父组件合并成同一个文件，一个组件的CSS可能会污染另一个组件的CSS，所以这时候需要使用scoped限制样式的作用域 -->

其中样式中的公共部分可以进行封装，以简化CSS代码 

在父组件中引入封装的vue子组件：

<template>
    <view>
      

       
    <block v-for="(item,index) in list" :key="index">
        <index-list :item="item" :index="index"></index-list>
    </block>
    

    </view>
</template>


<script>
    import indexList from "../../components/index/index-list.vue";
    export default {
        components:{
            indexList
        },
        data() {
            return {
                list:[
                    {
                        userpic:"../../static/demo/userpic/12.jpg",
                        username:"昵称",
                        isguanzhu:false,
                        title:"我是标题",
                        type:"img", // img:图文,video:视频
                        titlepic:"../../static/demo/datapic/11.jpg",
                        infonum:{

                            dingnum:11,
                            cainum:11,
                        },
                        commentnum:10,
                        sharenum:10,
                    },

                        username:"昵称",
                        isguanzhu:true,
                        title:"我是标题",
                        type:"video", // img:图文,video:视频
                        titlepic:"../../static/demo/datapic/11.jpg",
                        playnum:"20w",
                        long:"2:47",
                        infonum:{

                            dingnum:11,
                            cainum:11,
                        },
                        commentnum:10,
                        sharenum:10,
                    }
                ]
            }
        },
        onLoad() {

        },
        methods: {

        },
    }
</script>

<style>
    
</style>
