基于UniApp实现的仿微信顶部导航栏|uni-app原生导航栏自定义配置
实现了支持背景色渐变/标题居左/居中、搜索条、红点提示、按钮可自定义文字/iconfont图标/图片
uniapp原生导航
对于一些不是很复杂的顶部导航,当然使用原生导航栏实现是最佳选择
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,不过目前暂支持H5、App端,不支持小程序。
dcloud平台app-plus配置
在项目page.json里面配置app-plus
{
"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":{
...
}
}
}
}
},
那么如何监听按钮、输入框事件? uni-app给出了相应API,只需把onNavigationBarButtonTap
和onNavigationBarSearchInputChanged
,写在相应的页面中即可。
uniapp自定义导航栏
如何实现像淘宝、微信顶部导航栏,支持背景渐变、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" }
需在App.vue里面重新对顶部状态栏进行高度处理
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
}
})
},
