问题 I know that Selenium is an automated testing tool, but i'm trying to use it for RPA instead (things to do with my work environment) I've gotten the java code down, and it runs exactly how i want it. It takes data from an excel sheet, converts the data into java objects, then enters data into a web application. It works fine for the first 20-25 entries, then starts to slow down, and eventually crashes the application. I have a few thousand rows to enter. I've tried starting the chrome

问题 I have intermediate knowledge of chrome extension development. Context: Manifest has activeTab and contextMenus permissions. Clicking context menu item should inject content into DOM This works fine for regular web pages, but fails on default Chrome PDF viewer with the following error: Cannot access contents of the page. Extension manifest must request permission to access the respective host. However, if I inject the content first using a key command, then modify that content in the context

问题 Javascript files loaded into Google Chrome DevTools often lose their link with the workspace (the green dot disappears) when I'm revising code. The effect is that simple saves no longer work (I have to use 'save as' from the right-click menu) and debugging often stops. Using the 'Add folder to workspace' button has no effect. I have to close DevTools down and reopen it, a considerable nuisance. I've looked around online but can't see any reports of this happening to others. Is this a known

问题 I am really new working with Angular 4 and Chrome Extensions, but I have this code to comunicate my app in Angular with the Chrome extension. Code in Angular 4. public myObjectExtension : any; public getObjectChrome(){ chrome.runtime.sendMessage(extensionID, 'getObject', function(response) { console.log(response); this.myObjectExtension = reponse; }); } and I have this in my Chrome Extension. chrome.runtime.onMessageExternal.addListener( function(request, sender, sendResponse) { if(request ==

问题 In the Chrome Developer Tools network tab, there are times for Load and DomContentLoaded. These are marked as a red line and a blue line in the network tools. https://developer.chrome.com/devtools/docs/network When analysing some websites, multiple Load and DomContentLoaded event load marker lines appear with the later line updating the final Load and DomContentLoad times in the bottom bar. I am trying to understand why there are multiple event marker lines as the documentation says they

问题 I'm developing a progressive webapp and, in order to make sure it's working on mobile device (and particularly on Chrome for Android as it's 90% of users), I'm trying to test service worker on an Android device. Unfortunaltely, on Chrome for Android , I'm unable to register the service worker : An SSL certificate error occurred when fetching the script. Failed to load resource: net::ERR_CERT_AUTHORITY_INVALID I know service worker needs to be served over HTTPS so I have a self-signed

问题 I've an odd problem, i have a very simple node/expressjs app ( i have a much more complex one but this simple example shows the problem ). This app has three routes as shown here: var i = 0; app.route('/login') .get(function(req, res){ console.log('login', ++i); res.send('login'); }) app.route('/test') .get(function(req, res){ console.log('test', ++i); res.send('test'); }) app.route('/') .get(function(req, res){ console.log('index', ++i); res.send('index'); }) Pretty simple. Any time one of

问题 Does anyone know what the limit is on the maximum number of breakpoints that can be set with Google Chrome's Web Inspector? Thanks. 回答1: The number of breakpoints is only limited by your hardware resources (memory for storing them and CPU for quickly handling this lot of DOM elements.) 回答2: As far as I know there is no explicit limit for the number of breakpoints. However you should expect that some algorithms are not well optimized for a large number of breakpoints, e.g. some internal
