uniapp 微信小程序自己封装头部标题栏

一、首先要关闭原生导航栏 ：在pages.json 中设置  "navigationStyle":"custom"

二、在APP.vue中

onLaunch: function() {

   uni.getSystemInfo({

       success: function(e) {

       // #ifndef MP

          Vue.prototype.StatusBar = e.statusBarHeight;

              if (e.platform == 'android') {

                  Vue.prototype.CustomBar = e.statusBarHeight + 50;

              } else {

                  Vue.prototype.CustomBar = e.statusBarHeight + 45;

              };

              // #endif

              // #ifdef MP-WEIXIN

              Vue.prototype.StatusBar = e.statusBarHeight;

              let custom = wx.getMenuButtonBoundingClientRect();

              Vue.prototype.Custom = custom;

              Vue.prototype.CustomBar = custom.bottom + custom.top - e.statusBarHeight;

              // #endif        

              // #ifdef MP-ALIPAY

              Vue.prototype.StatusBar = e.statusBarHeight;

              Vue.prototype.CustomBar = e.statusBarHeight + e.titleBarHeight;

              // #endif

         }

      })

  },

三、在components文件夹下新建文件：cu-custom.vue

<template>

    <view>

        <view class="cu-custom" :style="[{height:CustomBar + 'px'}]">

            <view class="cu-bar fixed" :style="style" :class="[bgImage!=''?'none-bg text-white bg-img':'',bgColor]">

                <view class="action" @tap="BackPage" v-if="isBack">

                    <text class="cuIcon-back"></text>

                    <slot name="backText"></slot>

                </view>

                <view class="content">

                    <slot name="content"></slot>

                </view>

                <slot name="right"></slot>

            </view>

            <image :src="bgImage" class="postyle" :style="[{height:CustomBar + 'px'}]"></image>

        </view>

    </view>

</template>

<script>

    export default {

        data() {

            return {

                StatusBar: this.StatusBar,

                CustomBar: this.CustomBar

            };

        },

        name: 'cu-custom',

        computed: {

            style() {

                var StatusBar= this.StatusBar;

                var CustomBar= this.CustomBar;

                var style = `height:${CustomBar}px;padding-top:${StatusBar}px;`;

                return style

            }

        },

        props: {

            bgColor: {

                type: String,

                default: ''

            },

            isBack: {

                type: [Boolean, String],

                default: false

            },

            bgImage: {

                type: String,

                default: ''

            },

        },

        methods: {

            BackPage() {

                uni.navigateBack({

                    delta: 1

                });

            }

        }

    }

</script>

<style>

.postyle{

    position: fixed;

    width: 100%;

    top: 0rpx;

    left: 0rpx;

    z-index: 2;

}

</style>

四、将新建的组件在main.js中注册一下，需要的页面就可以直接引用啦

五、在需要的页面引用

<cu-custom bgColor="green-org" class="colorWhite" :isBack="false">

    <block slot="backText"></block>

    <block class="info-ifo" slot="content">首页</block>
</cu-custom>

好啦来看看效果吧
