How to Programmatically Scroll UWP WebView?

由 青春壹個敷衍的年華 提交于 2020-01-06 02:21:30
问题 I'm making a simply UWP (Universal Windows 10 App) web app using a webview. How can I return on the top of the page clicking on a button? I can't find it on the MSDN. 回答1: You can use window.scrollTo(0,0) method, it is a JavaScript method that scrolls the document to position "0" horizontally and "0" vertically. You can interact with the content of the WebView by using the InvokeScriptAsync method to invoke or inject script into the WebView content. For example: <Grid Background="

问题 I'm trying to send an image URI from a Website canvas to application with Javascript. In the Website I'm using the following function that relies on the html2canvas plugin: $("div.imagecapture").click(function() { html2canvas(document.getElementById('paper_trolley_center'), { onrendered: function(canvas) { var strDataURI = canvas.toDataURL("image/jpeg"); console.log('La imagen: '+strDataURI); jsNativeInterface.metodoDemo1(strDataURI); } }); }); The console.log outputs the URI, but the

混合 App 打开 H5 调试开关

背景 随着现在移动端设备的硬件性能的提高，现在web页面的体验逐渐变得可以接受，现在很多的应用都采用的Hybrid开发模式，一方面有利用了原生设备的API的优势（性能好、用户体验好），另一方面利用了web开发的优势（跨平台，开发成本低）。比如微信、QQ、58同城、美团、爱奇艺等等应用都是采用的Hybrid开发模式。 Hybrid应用如何去做自动化呢？ Hybrid是native嵌套了web，对于native页面，我们可以采用原生的自动化框架UIAutomator/XCUITest，而对于web页面，我们可以采用ChromeDriver，两者相结合完成自动化测试。现在流行的说法是移动端内嵌的web可以称为H5，虽然严格意义上来说H5不等同web。为了实现H5页面的自动化，其中H5页面的调试开关我们是必须要打开，否则通过inspector元素探测工具是定位不到页面的元素信息。 有源码的应用 针对公司内部团队开发的App，我们可以要开发直接在源代码中加上如下的代码，然后重新编译打一个debug包 if (0 != (getApplicationInfo().flags & ApplicationInfo.FLAG_DEBUGGABLE)) { WebView.setWebContentsDebuggingEnabled(true); } 无源码的应用 对于无源码的应用，如第三方线上App

Android webview check if page is in cache

由 十年热恋 提交于 2020-01-06 01:29:05
问题 in my app i'm using a webview to load a website for mobile devices. I've set up the webview for caching successfully. But if the device is offline and the user wants to visit a page which wasn't visited before it cannot be shown. This is clear because for a non visited page there is no counterpart in the cache. Therefore the webview shows the "Page not available" page. So to my question: Is it possible to check if a page exists in the cache before loading it in the webview? kind regards

JavaFX WebView doesn't execute JavaScript

由 旧街凉风 提交于 2020-01-05 21:12:30
问题 I am on Windows 8. I have a JavaFX app that creates a simple window with a webview control and loads the local file "test.html". "test.html" contains javascript (a simple "alert("hello");<(script>"). However, the javascript is ignored. What rendering engine does webview in JavaFX use? I have Firefox and IE installed. The latter executes JS contained in local files only if the users accepts to do so. So my assumption is that webview uses IE due to some configuration of my OS. Is this possible?
