问题 Assume browser default settings, and content is sent without expires headers. user visits website, browser caches images etc. user does not close browser, or refresh page. user continues to surf site normally. assume the browse doesn't dump the cache for any reason. The browser will cache images etc as the user surfs, but it's unclear when it will issue a conditional GET request to ask about content freshness (apart from refreshing the page). If this is a browser specific setting, where can I

问题 From Visual Studio, I'm accustomed to a call stack showing up at any breakpoint. Does Chrome have a call stack feature where I can see what functions preceded my breakpoint? If not, is there a substitute (3rd party solution that works with Chrome?) that developers use to see what functions led to a breakpoint? Edit: to be clear, I was expecting the call stack to appear within the javascript console in Chrome. 回答1: I don't know what version of Chrome you're using. I'm using Chromium 17 and the

问题 In Microsoft Edge, the following snippet will ignore the options passed to window.open() when url is a different origin than the current domain. But works it works fine in Chrome and Firefox, and when the domain is the same origin. const popupWindow = window.open( url, title, 'menu=no,toolbar=no,width=700,height=600,scrollbars=1,resizable=0,' + 'directories=no,location=no,screenX=0,screenY=0,top=48,left=48', ); I found a hacky workaround to get the window to size properly but this is really

问题 I have a working chat based on Meanjs and I would like to add a new feature to it that I see on other chats available: Feature: 1. when a message is received, the title of the window starts to switch between what it was, and a notification message like "new message" 2. when the browser or tab receives the focus, to stop the ongoing activity and reset back to the static page title The first one is simply to have a timer and change the page title during an interval, but I don't know how to get

问题 I was curious if there was a way to detect the user pressing the "stop navigation" button in the browser using javascript (or, even better, jQuery.) For example, if you click a link for a webpage that takes a while to load, you may want to show a spinning loader. But what if the user cancels navigation to the page?

问题 I've been using Flask and have linked the html I'm rendering to a css stylesheet. I've noticed that whenever I update my CSS code, I have to clear the cache in order to get it to update on the webpage.
