ext的grid和queryForm的整合处理

最近一直在考虑将ext进行标签处理，利用简单的标签和属性输出ext的ui效果。将常用的ext方法进行封装，提供统一的js函数给外部调用，以此提高开发的效率。下面是一点尝试的成果，需要改进的东西还很多很多。希望自己在5月份可以多多的整理文档，和做ext开发的朋友分享。

代码还是有不少的问题，不过基本的框架出来了。
下面是jsp代码：

<%@ page contentType="text/html;charset=UTF-8" %>

<%@ taglib uri="/WEB-INF/greatwall.tld" prefix="gw" %>

<%@ include file="/commons/taglibs.jsp" %>

<gw:html>

<gw:head>

<gw:title caption="Extjsptag TextTags Demo"/>

<%@ include file="/commons/button-icon.jsp" %>

</gw:head>

<gw:body>

<gw:script>

function func_button_submitForm(){

queryGrid('sysUserinfoList','sysUserinfo');

}

function func_button_resetForm(){

resetForm('sysUserinfo');

}

function func_button_addRecord(){

var page = new pageDefine('insert-sys_userinfo.jsp',200,600);

page.goPage();

}

function func_button_updateRecord(){

var page = new pageDefine('txn090903.do',200,600);

page.addGridValue('userId','sysUserinfoList:userId');

page.goPage();

}

function func_button_deleteRecord(){

var page = new pageDefine('txn090906.do');

page.addGridValues('userId','sysUserinfoList:userId');

page.deleteRecord('确认删除选中的记录？','sysUserinfoList');

}

</gw:script>

<gw:viewport>

<gw:block title="查询用户管理" name="sysUserinfo" columns="2" height="150" region="north" >

<gw:text name="username" fieldLabel="用户名" colspan="1" />

<gw:text name="email" fieldLabel="电子邮箱" colspan="1" />

<gw:submit name="button_submitForm" handler="func_button_submitForm" />

<gw:reset name="button_resetForm" handler="func_button_resetForm" />

</gw:block>

<gw:grid name="sysUserinfoList" title="用户管理列表" region="center" keyid="userinfoId" rownum="true" checkbox="true" url="txn090902.do" >

<gw:button text="增加用户管理" name="button_addRecord" handler="func_button_addRecord" icon="icon_add.gif" />

<gw:button text="修改用户管理" name="button_updateRecord" handler="func_button_updateRecord" enablerule="1" icon="icon_update.gif" />

<gw:button text="删除用户管理" name="button_deleteRecord" handler="func_button_deleteRecord" enablerule="2" icon="icon_delete.gif" />

<gw:cell dataIndex="userinfoId" header="用户表ID" width="100"/>

<gw:cell dataIndex="username" sortable="true" header="用户名" width="100" />

<gw:cell dataIndex="email" header="电子邮箱" width="100"/>

</gw:grid>

</gw:viewport>

</gw:body>

</gw:html>

下面是现实后的html代码：

<html>

<head>

<title>Extjsptag TextTags Demo</title>

.icon_add {

background: url('/sie/script/button-icon/icon_add.gif') 0 2 no-repeat !important;

ext 好像有一个taglib吧 http://www.exttld.com/ 回复更多评论

@阳衡锋
确实有一个并且还有不少
我希望我的这个标签可以和一部分的后台程序结合起来使用，完成用户权限的控制。回复更多评论

一直在想，那么多人那么痛苦的要把b/s整成c/s，大量精力都花在了UI而不是业务逻辑上，何必呢？回复更多评论

# re: ext的grid和queryForm的整合处理 2009-05-05 13:40 王兵

@tee
业务逻辑其实是核心的东西
但是架构师是不需要关心具体的业务逻辑
我们公司有自己的产品自己的平台、UI、快速开发环境等等
这些都和业务没关系回复更多评论

我认为用模板比用标签封装方便，标签调试起来太麻烦回复更多评论
