问题 I wanted to know when the browser is closed at server side in asp.net 2.0. How to detect in code behind? 回答1: client side script: < body onbeforeunload="window.open('http://www.website.com/browserclosed.aspx','mywindow','width=1,height=1');"> server side script (browserclosed.aspx): // page_load int userId = Convert.ToInt32(request.session("userId")); ReportBrowserClosed(userId); // Do what you want in ReportBrowserclosed() method 回答2: Short answer: you can't do that directly since http is

问题 I have a use case where I'd like to intercept and log HTTP OPTIONS calls. I understand these are being done by the browser as part of CORS I've tried monkeypatching XMLHttpRequest, and also a service-worker where I'd intercept via the "fetch" event. However I am only ever able to capture non OPTIONS calls (GET, PUT, POST) How can I intercept the OPTIONS calls? I clearly see them being done in the network tab 回答1: CORS preflight requests are hard-coded into browsers as a browser security

问题 All, My application supports IE7+, MOZILLA and other modern browsers. Anybody know of a very good browser detection and redirection PHP class? I came across this, but I am not sure if anybody used this: http://chrisschuld.com/projects/browser-php-detecting-a-users-browser-from-php/#typicalusage Thanks 回答1: All you need is get_browser() and a recent browscap.ini that maps the user-agent string to a browser/version and its capabilities. You can get a usually very up-to-date browscap.ini version

问题 I just tried to write the following rule to style the input placeholder for browsers that support it: #main input::-webkit-input-placeholder, #main input:-moz-placeholder { color: #888; font-style: italic; } The problem is that the rule isn't applied. However, if I break it up like this instead it works just fine: #main input::-webkit-input-placeholder { color: #888; font-style: italic; } #main input:-moz-placeholder { color: #888; font-style: italic; } Why can I not group browser-specific

问题 I have added smooth scrolling to a site of mine using this piece of JavaScript when clicking on hash links. $('a[href*=#]') .click(onAnchorClick); function onAnchorClick(event) { return ! scrollTo(this.hash); } function scrollTo(target) { var e = $(target); var y = e.exists() ? e.offset().top : 0; if(y == 0 && target != '#top') return false; if(Math.max($('html').scrollTop(), $('body').scrollTop()) != y) $('html,body') .animate({scrollTop: y}, 500, function() { location.hash = target; } );

问题 My company has a shared network folder for projects. This folder contains a sub-folder for each of our clients. Each sub-folder contains all the information for the projects done for those clients. Makes sense, yea? OK. I have been given a task: When in our company's MS CRM and viewing a client account, allow the user to click a button that will open explorer to the project folder for that account. Sounds easy. Did a bit of hunting online. This looks nice: http://blogs.msdn.com/crm/archive

问题 I am trying to implement a browser-like little application that would allow me to modify the viewed web-sites appearance (e.g. make the font for links bigger). It is designed for Microsoft Surface, to be used on a huge touchscreen. It uses WPF for the UI. I am intending to use a WebBrowser control for this task. However there are two classes called WebBrowser in the docs. One of them is in System.Windows.Forms , the other in System.Windows.Controls . The first one gives access to DOM model,

问题 This might sound silly, but as a developer, I'm using the debugger in Chrome every day to test my web applications, but although these tools are valuable for us developers, it might also be used against us by users how wants to mess with our systems. You probably know that it is fairly easy, using the debugger, to re-enable a button that was previously set to disabled, or change the value of hidden tags or variables.
