}新建组件 HeadNav
!--注意1、在传入宽度或者高度时如果是Number数据传入的值为px大小,无需带单位组件自动计算2、在使用此导航栏时建议传入UI规定的导航栏高度此高度只针对除微信小程序的其他平台有效微信小程序的导航栏高度组件自计算

/style
使用
引入组件使用
templateviewHeadNav text-content测试导航栏 nav-background-color#fff/HeadNavaaa/view
/templatescriptimport HeadNav from /components/HeadNav.vueexport default {components: {HeadNav},data() {return {title: Hello,}},onLoad() {},methods: {}}
/scriptstyle
body {background-color: aliceblue;
}
/style如果需要定义状态栏前景字体的颜色可以设置 navigationBarTextStyle 只能设置 white 或 black
{pages: [{path: pages/index/Index,style: {navigationBarTextStyle: black}}],globalStyle: {navigationStyle: custom,backgroundColor: #F8F8F8},uniIdRouter: {}
}效果 uview 导航栏使用
引入 uview 根据文档引入 Navbar 自定义导航栏 | uView 2.0 (uviewui.com) 使用 u-navvar
templateview!-- 2.0.19支持autoBack默认为false --u-navbar title个人中心 rightClickrightClick :autoBacktrue/u-navbar/view
/templatescriptexport default {components: {},data() {return {title: Hello,}},onLoad() {},methods: {rightClick() {console.log(rightClick);},leftClick() {console.log(leftClick);}}}
/scriptstylebody {background-color: aliceblue;}
/style效果
