From the current development trend of Web applications, with the emergence of Ajax and other technologies, the B/S architecture is becoming more and more abundant in performance technologies, and there is a "C/S" trend, we now describe some usage
The Web application UI of Ajax-like brushless newest is often used to languages such as "desktop-style operation interface" (the paper recently published by Miss Li and his disciples on CET is about so
).
If the new anti-bot technology meets the rich side of the client controls in the C/S architecture, the free use of C/S requires another technology, google gear is one of the representatives of Firefox V3's offline application features in development.
Google gear works like this: it provides a local server, a local database, and a work pool.
Pool ).
When using gear technology, you can download the website data before going offline to create a local cache, and so on, you can "normally" use the website function offline. When you re-connect to the network, you can execute synchronization again.
Function to synchronize offline operations to the server.
The procedure and method are as follows:
1. Download Google Gear
Log on to the http://gears.google.com/download and install Google gear. If you have installed Google gear, the software download bar will display"Google gears is installed
.
2. After the installation is complete, When you access a website that supports Google gear using a browser (taking Firefox as an example), a dialog box will pop up asking if gear is allowed.
3. If the site is allowed to be used, a downward arrow will be found on the user interface. Clicking Gear will download necessary resources and client running files and place the site offline.
4. In the offline status, you can still use the corresponding functions on the site. Theoretically, the user interface and experience in the offline status will be the same as that in the online status, it depends on the development capability of different sites.
5. After offline use, you can also click the arrow (which should be an up arrow) when connecting to the Internet to synchronize data between the local machine and the network server.
The above example and screenshot are completed in Windows XP + Firefox 2.0 + Google gear 0.3.13 Based on Google Reader site (http://www.google.com/reader/view.
Google
The current version of gear is 0.3. I personally am very optimistic about this application and have been watching for a long time. However, there are still not many websites that support this technology, except Google
Google Reader and Google Docs (the above applications are only available in the English version, and the Chinese version does not yet support gear), so there are only a few such applications as zoho.
We hope that Google will provide more gear development technical support. For me, we hope that some of our applications will support such operation modes.
