自定义导航栏

修改 pages.json

在 pages.json 中将 navigateionStyle 设为 custom

新建 systemInfo.js

systemInfo.js 用来获取当前设备的机型系统信息，放在 common 目录下

/*** 此 js 文件管理关于当前设备的机型系统信息*/
const systemInfo = function() {/****************** 所有平台共有的系统信息 ********************/// 设备系统信息let systemInfomations = uni.getSystemInfoSync()// 机型适配比例系数let scaleFactor = 750 / systemInfomations.windowWidth// 当前机型-屏幕高度let windowHeight = systemInfomations.windowHeight * scaleFactor //rpx// 当前机型-屏幕宽度let windowWidth = systemInfomations.windowWidth * scaleFactor //rpx// 状态栏高度let statusBarHeight = (systemInfomations.statusBarHeight) * scaleFactor //rpx// 导航栏高度  注意：此导航栏高度只针对微信小程序有效 其他平台如自定义导航栏请使用：状态栏高度+自定义文本高度let navHeight = 0 //rpx/****************** 微信小程序头部胶囊信息 ********************/// #ifdef MP-WEIXINconst menuButtonInfo = wx.getMenuButtonBoundingClientRect()// 胶囊高度let menuButtonHeight = menuButtonInfo.height * scaleFactor //rpx// 胶囊宽度let menuButtonWidth = menuButtonInfo.width * scaleFactor //rpx// 胶囊上边界的坐标let menuButtonTop = menuButtonInfo.top * scaleFactor //rpx// 胶囊右边界的坐标let menuButtonRight = menuButtonInfo.right * scaleFactor //rpx// 胶囊下边界的坐标let menuButtonBottom = menuButtonInfo.bottom * scaleFactor //rpx// 胶囊左边界的坐标let menuButtonLeft = menuButtonInfo.left * scaleFactor //rpx// 微信小程序中导航栏高度 = 胶囊高度 + (顶部距离 - 状态栏高度) * 2navHeight = menuButtonHeight + (menuButtonTop - statusBarHeight) * 2// #endif// #ifdef MP-WEIXINreturn {scaleFactor,windowHeight,windowWidth,statusBarHeight,menuButtonHeight,menuButtonWidth,menuButtonTop,menuButtonRight,menuButtonBottom,menuButtonLeft,navHeight}// #endif// #ifndef MP-WEIXINreturn {scaleFactor,windowHeight,windowWidth,statusBarHeight}// #endif
}export {systemInfo
}

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

<template><view><HeadNav text-content="测试导航栏" nav-background-color="#fff"></HeadNav>aaa</view>
</template><script>import HeadNav from '@/components/HeadNav.vue'export default {components: {HeadNav},data() {return {title: 'Hello',}},onLoad() {},methods: {}}
</script><style>
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

<template><view><!-- 2.0.19支持autoBack，默认为false --><u-navbar title="个人中心" @rightClick="rightClick" :autoBack="true"></u-navbar></view>
</template><script>export default {components: {},data() {return {title: 'Hello',}},onLoad() {},methods: {rightClick() {console.log('rightClick');},leftClick() {console.log('leftClick');}}}
</script><style>body {background-color: aliceblue;}
</style>
