自定义导航栏高度组成:状态栏(绿色部分)、导航栏(蓝色部分)
通过调用 wx.getSystemInfoSync 获取
const res = wx.getSystemInfoSync() this.setData({ statusBarHeight:res.statusBarHeight })
通过获取右上角胶囊的位置信息计算,navBarPadding为导航栏上下的间隙
let res = wx.getMenuButtonBoundingClientRect() let navBarPadding = (res.top - this.data.setStatusBarHeight) * 2 this.setData({ navBarHeight: res.height + navBarPadding })
app.js:
App({ onLaunch () { this.setStatusBarHeight() this.setNavBar() }, //设置系统状态栏高度 setStatusBarHeight(){ try { const res = wx.getSystemInfoSync() this.globalData.statusBarHeight = res.statusBarHeight }catch(error){ console.log(error) } }, //设置导航栏height setNavBar(){ let res = wx.getMenuButtonBoundingClientRect() let navBarPadding = (res.top - this.data.setStatusBarHeight) * 2 this.globalData.navBarHeight = res.height + navBarPadding }, globalData: { statusBarHeight: 20, navBarHeight: 44 } })
wxml:
<view class="top-bar-wrap"> <view class="top-bar-main" style="padding-top:{{statusBarHeight}}px;height:{{navBarHeight}}px"> 自定义导航栏 </view> </view>
wxss:
.top-bar-wrap{
z-index: 9999;
position: fixed;
top: 0;
left: 0;
width: 100%;
}
.top-bar-main{
width: 100%;
display: flex;
justify-content: center;
align-items: center;
color:#fff;
}
js:
const app = getApp()
Component({ data: { statusBarHeight: app.globalData.statusBarHeight, navBarHeight: app.globalData.navBarHeight } })
setStatusBarHeight、setNavBar这两个方法最好写到app.js中,获取好放在app.globalData中,这两个高度可能不止自定义导航栏需要用到。
比如使用了自定义导航栏的页面,因为自定义导航栏是fixed定位脱离文档流,导致整个页面就会上移,所以要给页面加上padding-top,高度跟自定义导航栏的高度一致,即 statusBarHeight + navBarHeight。
