}

自定义头部导航栏代码

wxml部分

wxss部分

.cu-custom{display:block;position:relative;}
.cu-custom.cu-bar{display:flex;align-items:center;justify-content:space-between;position:fixed;width:100%;top:0;min-height:100rpx;padding-right:220rpx;box-shadow:0rpx0rpx0rpx;z-index:9999;background-color:#fff;}
.cu-custom.cu-bar.border-custom{position:relative;background:rgba(255,255,255,0.5);border-radius:1000rpx;height:30px;}
.cu-custom.cu-bar.action{display:flex;align-items:center;height:100%;justify-content:center;max-width:100%;}
.cu-custom.cu-bar.action:first-child{margin-left:30rpx;font-size:30rpx;}
.cu-custom.cu-bar.border-customtext{display:block;flex:1;margin:auto!important;text-align:center;font-size:34rpx;}
.cu-bar.content{width:calc(100%-440rpx);position:absolute;text-align:center;left:0;right:0;bottom:0;top:0;margin:auto;height:60rpx;font-size:32rpx;line-height:60rpx;cursor:none;pointer-events:none;text-overflow:ellipsis;white-space:nowrap;overflow:hidden;}

js部分

constApp=getApp();
Component({
options:{
addGlobalClass:true,
multipleSlots:true
},
properties:{
isBack:{
type:[Boolean,String],
default:false
},
bgColor:{//类名
type:String,
default:''
},
bgImage:{//仅支持网络地址
type:String,
default:''
},
},
data:{
StatusBar:App.GlobalData.StatusBar,
CustomBar:App.GlobalData.CustomBar,
Custom:App.GlobalData.Custom,
isShare:App.GlobalData.share
},
methods:{
BackPage(){
wx.navigateBack({
delta:1
});
},
toHome(){
wx.reLaunch({
url:'/pages/index/index',
})
}
}
})

app.js判断是否分享

App({
GlobalData:{
share:false,
StatusBar:0,
Custom:0,
CustomBar:0
},
onLaunch:function(){
letself=this
letsystemInfo=wx.getSystemInfoSync()
self.GlobalData.StatusBar=systemInfo.statusBarHeight;
if(wx.getMenuButtonBoundingClientRect){
letcustom=wx.getMenuButtonBoundingClientRect();
self.GlobalData.Custom=custom;
self.GlobalData.CustomBar=custom.bottom+custom.top-systemInfo.statusBarHeight;
}
})

因为组件css里不支持伪类元素所以写在app.css

/*自定义头部导航栏图标*/
.cu-custom[class*="icon-"]{font-family:"iconfont"!important;font-size:inherit;font-style:normal;}

@font-face{font-family:"iconfont";
