问题 Use case; click on marker opens infowindow, click on map closes it. stopEventPropagation is used to prevent that marker click propagates to the map (click on map would close the infowindow), this works fine in chrome, but in mobile safari (iphone 5) or chrome itself emulating the same phone, the event isn't stopped (thus the infobox not shown, or inmediatelly closed). function stopEventPropagation(e) { var evt = e ? e : window.event; evt.cancelBubble = true; if (evt.stop) evt.stop(); if (evt

问题 I'd like to test my webpages loading steps, but as I'm lazy, I would love to avoid changing the throttling settings every time after my page has been loaded. Here would be the perfect flow: page loads without throttling after this load, all requests are slowed down with +/- 10s ping This way, I wouldn't have to change throttling for page reloading during dev but I still have really slow to test my loader steps. 来源： https://stackoverflow.com/questions/52790399/chrome-devtools-throttle-network

问题 I'm using Chrome browser and I'm trying to create a WebSocket connection (using javascript) but sometimes I get an error. When I'm looking in Developer Tools for the WS connection, I see OPCODE -1. What does this mean? 回答1: WebSocket OPCODEs describe how to interpret the frame. The OPCODES are formally between 0-10, OPCODE -1 says "not frame that can be used": https://developer.mozilla.org/en-US/docs/Web/API/WebSockets_API/Writing_WebSocket_servers#Exchanging_Data_Frames https://tools.ietf

问题 I'm building an ASP.NET MVC3 website. I have some javascript in my .cshtml file: <div>hello!</div> <script type="text/javascript"> $(document).ready(function () { alert("ready!"); }) </script> Google Chrome's built-in debugger doesn't see this javascript snippet, so I can't debug it. How can I set a breakpoint in this javascript snippet in Google Chrome's built-in debugger? 回答1: Weird, works great for me: Go to the Scripts tab You will see a dropdown list of all referenced javascript files,

问题 In the old version of Chrome (not sure which version, I know it was quite some time ago), I could type the following into a console using the Chrome Developer Tools, and it would give me all associated properties of the newly created object: document.createElement('a'); Now, when I do the same, I'm given very little back, and I can barely do anything with the returned item in the console, whereas I would just like to inspect it. How do I view all the properties of this element, etc. as with

问题 I am familiar with how to use the Google Chrome Web Inspector to manually save a webpage as a HAR file with the content. I would like to automate this. In my searches for tools to automate the generation of a HAR file, I have found some solutions, but none of them save the content of the resources. I have tried the following without any luck: https://github.com/ariya/phantomjs/blob/master/examples/netsniff.js https://github.com/cyrus-and/chrome-har-capturer Getting the content of the page you

问题 I have an issue with my app that I cannot find solution for anywhere. I use react-router-redux and syncHistoryWithStore . When I click on my navigation to change a route using Link the new route loads, URL in the browser updates, however the location state doesn't update unless I click the Link two times.
