uniapp动态设置顶部导航栏

在pages.json页面

{
	"path": "pages/index/index",
	"style": {
		"navigationBarTitleText": "",
		"navigationBarBackgroundColor": "#000000",
		"app-plus": {
			"bounce": "none"
		}
	}
}

在页面的onLoad中

let pages = getCurrentPages()
let page = pages[pages.length - 1];
let currentWebview = page.$getAppWebview();
let titleNView = currentWebview.getStyle().titleNView
titleNView.autoBackButton = false//隐藏返回按钮
currentWebview.setStyle({
	titleNView: titleNView
})

let titleNView = currentWebview.getStyle().titleNView
console.log(titleNView)
//打印结果
{
	"autoBackButton": true,
	"backgroundColor": "#F8F8F8",
	"dock": "top",
	"height": 44,
	"position": "dock",
	"statusbar": {},
	"tags": [],
	"titleColor": "#000000",
	"titleText": "纸板入库",
	"type": "default"
}

设置延时

titleNView.autoBackButton = true
currentWebview.setStyle({
	titleNView: titleNView
})
uni.setNavigationBarColor({
	frontColor: "#ffffff", //文字颜色
	backgroundColor: "#000000" ,//底部背景色
})
uni.setNavigationBarTitle({
	title: title//想要显示的顶部标题
});
