uniApp自定義導航條|仿京東、淘寶導航欄

使用 uniapp自定義導航欄|仿微信、淘寶頂部導航條,支持背景漸變、標題居左/居中、搜索條,圓點提示,按鈕可自定義傳入文字/字體圖標/圖片

uniapp原生導航

uni-app原生導航欄也能實現一些頂部自定義按鈕+搜索框,只需在page.json裏面作一些配置便可。設置app-plus,dcloud平臺對app-plus作了詳細說明:app-plus配置,不過目前暫支持H五、App端,不支持小程序。
vue


需在項目page.json裏面配置app-plusandroid

{
    "path": "pages/ucenter/index",
    "style": {
        "navigationBarTitleText": "個人",
        "app-plus": {
            "titleNView": {
                "buttons": [
                    {
                        "text": "\ue670",
                        "fontSrc": "/static/iconfont.ttf",
                        "fontSize": "22px",
                        "float": "left"
                    },
                    {
                        "text": "\ue62c",
                        "fontSrc": "/static/iconfont.ttf",
                        "fontSize": "22px"
 
                    }
                ],
                "searchInput":{
                    ...
                }
            }

uniapp自定義導航欄

如何實現像微信、京東頂部導航欄,支持標題居左、居中、搜索條、按鈕自定義。。。 將navigationStyle設爲custom或titleNView設爲false時,原生導航欄不顯示,這時就能自定義導航欄 json

 ` "globalStyle": { "navigationStyle": "custom" } ` 小程序

 具體效果實例以下:bash

H5效果(如上圖)微信


小程序效果(如上圖)app


App端效果(如上圖)字體

不過在 H五、小程序、App端狀態欄需從新計算處理,下面爲你們提供一種處理方法,在App.vue裏面設置便可
flex

onLaunch: function() {
    uni.getSystemInfo({
        success:function(e){
            Vue.prototype.statusBar = e.statusBarHeight
            // #ifndef MP
            if(e.platform == 'android') {
                Vue.prototype.customBar = e.statusBarHeight + 50
            }else {
                Vue.prototype.customBar = e.statusBarHeight + 45
            }
            // #endif
            
            // #ifdef MP-WEIXIN
            let custom = wx.getMenuButtonBoundingClientRect()
            Vue.prototype.customBar = custom.bottom + custom.top - e.statusBarHeight
            // #endif
            
            // #ifdef MP-ALIPAY
            Vue.prototype.customBar = e.statusBarHeight + e.titleBarHeight
            // #endif
        }
    })
},

居中就設置center便可ui


<header-bar :isBack="true" titleTintColor="#fff" :bgColor="{'background-image': 'linear-gradient(45deg, #007AFF 10%, #005cbf)'}" search>
    <text slot="back" class="uni_btnIco iconfont icon-arrL"></text>
