browser

问题 I am doing browser automation and I am blocked at a certain point: at a moment, I ask the browser to click on a button, which in turn open up a new window. But sometimes the Internet is too slow, and so this new window takes time to load. I want to know how can I ask Selenium to wait until this new fresh window is fully loaded. Here's my code: driver.switch_to.default_content() Button = WebDriverWait(driver, 20).until(EC.element_to_be_clickable((By.ID, 'addPicturesBtn'))) Button.click()

问题 Socket.io client API documentation suggests that the client should pass the self signed certificate in the connection request to the server: // client-side const socket = io({ca: fs.readFileSync('server-cert.pem'),rejectUnauthorized: false}); This works great in a node environment. How to make this work in a BROWSER javascript app? I am facing two issues: How can I include the certificate file in the browser app? readfileSync cannot find the file If I only include rejectUnauthorized: false in

问题 Right now, I am working on a part of a project which supports drag and drop. Look at the picture for clarification: Even though it is German, I guess it is straightforward: The User can drag the blue boxes from the top saying "Verfügbare Empfänger" on the gray areas below. This works just fine. On mobile devices, I just removed the drag and drop and the gray areas and can add the blue boxes by clicking on them. Now for the actual problem: in order to detect touch, I used the following

问题 Following solutions (actually it is only one) doesn't work to me : How to get a name of default browser using python How to get name of the default browser in windows using python?

问题 When we see conformance chart, such as https://caniuse.com/#search=xpath and https://developer.microsoft.com/en-us/microsoft-edge/platform/status/domlevel3xpath/?q=xpath, it's usually about DOM Level 3 XPath that focuses on accessing DOM object using XPath 1.0 , but not necessarily XPath 3.0 or higher. Question 1 - Is there any explicit version requirement for browsers by W3C etc. to support newer versions of XPath? This XPath 1.0 feature works: document.evaluate( 'normalize-space(" X ")',

问题 I have a TWebBrowser placed on a form with the designMode enabled. Bellow the browser I have a close button with the Caption set to 'Clos&e'. When I am editing the contents of a document inside the WebBrowser and I press the key E the button close is called. It appears that it is treating TWebBrowser like other controls that don't handle keys and/or don't accept chars (e.g. TButton). How can I solve this? Thanks in advance. 回答1: Descend from TWebBrowser, override the CN_CHAR message handler,

问题 I am dynamically loading my JavaScript as a "plugin" on a third party's page and would like to verify that it's coming from me. I can use the content SRI, however I update the library frequently and need it to be dynamically loaded. Below is an example of what I'd like to see.
