A large number of our current applications rely on the script processing capabilities of browsers (mainly IE). It is really slow when running on some old machines, however, the current mainstream models have no problems. We have designed a complete set of Web development frameworks, which will become more and mor

As shown in my previous article, XCodeBuilder can not only generate. Net layer-3 code, but also generate Processing Layer Code and Ext script. The following is a grid example. This file is: ext_editgrid_products.js, used to display, edit, and delete data in the products table.
The Code is as follows:
Var productsgrid;Var productsstore;Var productslimit = 25; // number of entries per pageVar productsListPostUrl = "/management/procrequest/Proc_produc

Paging is basically an eternal topic for web programmers. fortunately, no matter what development language we have a lot of controls to use. there are also paging controls in ext, but the official example is to use scripttagproxy, while the vast majority of online examples are either scripttagproxy or httpproxy for data loading. however, in many cases, we must not load local data (for example, when two people use interfaces for development ), the foll
From the library perspective, ext (a friend who likes Chinese can visit its Chinese site) is not much different from prototype jquery Yui, but it has its advantages, complete oo support, mature general-purpose widgets, and support themes, good scalability, fast update and release of new widgates,CommunityIt is also very lively.
