About the definition of the progress bar (loading) style of uniapp’s webview component

#1. The editor is learning uni-app recently. Because there are many external web pages loaded in the project. So the webview component must be used. But the server of some websites (don’t think wrongly) is because this website is a virtual currency trading website. You know. However, accessing such websites in the app often requires a blank period of three to four seconds.
There is still a progress bar on the web page. But the style is too ordinary. So I did it on a whim. Two modifications have been made to the progress bar. Of course, they are all built-in or supported by uni-app itself. You can read the documentation.
The first normal change the color of the progress bar.
1. According to the official documentation, add: webview-styles="webviewStyles"

2. Set the color in data()

data() {
			return {
				webviewStyles: {
                     progress: {
                        color: '#FF3333'
                    }
                }
			};
		},

3 .Look at the picture

#The second type is a relatively advanced loading effect. Look at the picture

1. The implementation code is as follows

data() {
			return {
				 webviewStyles: {
                     progress: false //必须要设置为false
                }
			};
		},

2. The js code can be written in onload

var pages = getCurrentPages();
	var page = pages[pages.length - 1];
	var currentWebview=page.$getAppWebview();
	setTimeout(function(){
		var web_view= currentWebview.children();
		var w=plus.nativeUI.showWaiting();
		web_view[0].addEventListener("loading",function(){
			w.show();
		},false);
		
		web_view[0].addEventListener("loaded",function(){
			w.close();
			w=null;
		},false);
	},600)
