由 烂漫一生 提交于 2019-12-20 04:13:17

Application Cache or Service Workers - which to use in 2016/Q2?

由 孤人 提交于 2019-12-18 10:50:14
问题 Quick question for discussion really, as I wanted to have input from different people. I am in the process of developing a web page app that must be available offline. Now to do this, as I understand it, you would go about using either the application caching feature or by using service workers. However, here is the conundrum I have. When researching the application cache, the MDN clearly states: Deprecated: This feature has been removed from the Web standards. Though some browsers may still

Standalone MVC3 webapp?

由 大城市里の小女人 提交于 2019-12-11 00:03:36
问题 Rather than going down the Silverlight/WPF route, i'd like to build my (single-user) application in HTML5 with MVC3 as the backend. Is this possible? Is it possible or practical to use this for a standalone desktop application? I could set it up in IIS and off I go, but that's not the idea - its not portable, requires a fixed directory, and I can't just fire up my application anywhere I take it without installing IIS! 回答1: I have experimented with a standalone in-process .Net based web server

navigator.onLine still true when turning off WiFi, false when set “work offline” in browser

由 时间秒杀一切 提交于 2019-12-09 17:46:25
问题 navigator.onLine is still returning true when I turn off Wi-Fi (Airport on my notebook in OS X). This is counterintuitive behavior. But when I set "work offline" in a browser like Firefox, it correctly returns false. Is this expected? alert(navigator.onLine ? "online" : "offline"); 回答1: Yes. The browser doesn't provide network connectivity information to the page, but rather uses Work Offline's status as the value. 回答2: Use the window.addEventListener to detect network updates: window

MS Access Application Work offline

由 拟墨画扇 提交于 2019-12-09 04:36:29
I have an MS Access (2010) application linked to SQL Server (2012) via linked tables. Is there any way that I can have the users work offline and sync to the server when connected? Thanks in advance The method to do it is having linked tables to tables on 2 DBs: to the SQL server, and to a local copy Access DB file. You copy date from remote to local DB Have the user work on local copy Synchronize data back to remote DB If you keep the local tables with the same names, and add some prefix to links to remote table names ("Remote" or "rmt"), You can keep most of you logic: You still process same
