运用uni-app开发的uniapp自定义导航栏|仿微信、淘宝顶部导航条,支持背景渐变、标题居左/居中、搜索条,圆点提示,按钮可自定义传入文字/字体图标/图片
在uni-app中实现导航效果,一是通过原生导航栏、二是自定义导航栏。
UniApp原生导航配置:
uni-app原生导航栏也能实现一些顶部自定义按钮+搜索框,只需在page.json里面做一些配置即可。设置app-plus,dcloud平台对app-plus做了详细说明:app-plus配置,不过目前暂支持H5、App端,不支持小程序。
如上图,通过配置page.json里面的app-plus选项即可实现
- {
- "path": "pages/ucenter/index",
- "style": {
- "navigationBarTitleText": "我的",
- "app-plus": {
- "titleNView": {
- "buttons": [
- {
- "text": "\ue670",
- "fontSrc": "/static/iconfont.ttf",
- "fontSize": "22px",
- "float": "left"
- },
- {
- "text": "\ue62c",
- "fontSrc": "/static/iconfont.ttf",
- "fontSize": "22px"
-
- }
- ],
- "searchInput":{
- ...
- }
- }
- }
- }
- },
复制代码
UniApp自定义导航配置:
如何实现像微信、京东顶部导航栏,支持标题居左、居中、搜索条、按钮自定义。。。 将navigationStyle设为custom或titleNView设为false时,原生导航栏不显示,这时就能自定义导航栏
"globalStyle": { "navigationStyle": "custom" }
效果如下图:
H5、小程序、App端顶部状态栏高度处理
- 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
- }
- })
- },
复制代码
- <header-bar :isBack="false" title="标题信息" titleTintColor="#fff">
- <text slot="back" class="uni_btnIco iconfont icon-arrL"></text>
- <text slot="iconfont" class="uni_btnIco iconfont icon-search" @tap="aaa"></text>
- <text slot="iconfont" class="uni_btnIco iconfont icon-tianjia" @tap="bbb"></text>
- <!-- <text slot="string" class="uni_btnString" @tap="ccc">添加好友</text> -->
- <image slot="image" class="uni_btnImage" src="../../static/logo.png" mode="widthFix" @tap="ddd"></image>
- </header-bar>
复制代码 实现了如下效果,做了一张大图:
- /**
- * @tpl 顶部导航模板(自定义) by andy Q:282310962
- */
- <template>
- <view class="uni_topbar" :style="style">
- <view class="inner flexbox flex_alignc" :class="[fixed ? 'fixed' : '']" :style="[{'height': customBarH + 'px', 'padding-top': statusBarH + 'px', 'color': titleTintColor}, bgColor]">
- <!-- 返回 -->
- <!-- <text class="uni_icoBack iconfont icon-arrL" v-if="isBack" @tap="goBack"></text> -->
- <view v-if="isBack" @tap="goBack">
- <slot name="back"></slot>
- </view>
- <slot name="headerL"></slot>
- <!-- 标题 -->
- <!-- #ifndef MP -->
- <view class="flex1" v-if="!search && center"></view>
- <!-- #endif -->
- <view class="uni_title flex1" :class="[center ? 'uni_titleCenter' : '']" :style="[isBack ? {'font-size': '32upx', 'padding-left': '0'} : '']" v-if="!search && title">

- }
- },
- props: {

- search: { type: [Boolean, String], default: false },
- searchRadius: { type: [Boolean, String], default: false },
- fixed: { type: [Boolean, String], default: false },
- },
- computed: {
- style() {
- let _style = `height: ${this.customBarH}px;`
- return _style
- }
- },
- methods: {
- goBack() {
- uni.navigateBack()
- }
- }
- }
- </script>
