好,静态的页面已经可以完成了,下面就开始加上后台的处理部分。
查看easyui的API可以看到,如果需要后台支持的话,需要设置url属性,下面用java来做后台处理数据。
传输的格式用的是JSON,如果你还不知道JSON那么就去baidu一下好了。
后台现在只添加了struts和spring的支持,如果需要连接数据库那么添加上hibernate或者用jdbc等数据处理层的框架好了
好新建jsp页面,添加默认的编码格式为UTF-8
代码
<%
@ page language
=
"
java
"
contentType
=
"
text/html; charset=UTF-8
"
pageEncoding
=
"
UTF-8
"
%>
<% @ taglib uri = " http://struts.apache.org/tags-bean " prefix = " bean " %>
<% @ taglib uri = " http://struts.apache.org/tags-html " prefix = " html " %>
<% @ taglib uri = " http://struts.apache.org/tags-logic " prefix = " logic " %>
<% @ taglib uri = " http://struts.apache.org/tags-bean " prefix = " bean " %>
<% @ taglib uri = " http://struts.apache.org/tags-html " prefix = " html " %>
<% @ taglib uri = " http://struts.apache.org/tags-logic " prefix = " logic " %>
设置默认路径
<%
String path = request.getContextPath();
String basePath = request.getScheme() + " :// " + request.getServerName() + " : " + request.getServerPort() + path + " / " ;
request.setAttribute( " basepath " ,basePath);
%>
String path = request.getContextPath();
String basePath = request.getScheme() + " :// " + request.getServerName() + " : " + request.getServerPort() + path + " / " ;
request.setAttribute( " basepath " ,basePath);
%>
添加默认的css和必须的js包
代码
<
link rel
=
"
stylesheet
"
type
=
"
text/css
"
href
=
"
${basepath}resources/default.css
"
/>
< link rel = " stylesheet " type = " text/css " href = " ${basepath}resources/themes/default/easyui.css " />
< link rel = " stylesheet " type = " text/css " href = " ${basepath}resources/themes/icon.css " >
< script type = " text/javascript " src = " ${basepath}resources/jquery-1.4.2.min.js " ></ script >
< script type = " text/javascript " src = " ${basepath}resources/jquery.easyui.min.js " ></ script >
< script type = " text/javascript " src = " ${basepath}resources/jquery[1].json-1.3.min.js " ></ script >
< link rel = " stylesheet " type = " text/css " href = " ${basepath}resources/themes/default/easyui.css " />
< link rel = " stylesheet " type = " text/css " href = " ${basepath}resources/themes/icon.css " >
< script type = " text/javascript " src = " ${basepath}resources/jquery-1.4.2.min.js " ></ script >
< script type = " text/javascript " src = " ${basepath}resources/jquery.easyui.min.js " ></ script >
< script type = " text/javascript " src = " ${basepath}resources/jquery[1].json-1.3.min.js " ></ script >
OK,现在可以开始写生成表格的程序了。
在$(function(){}中添加调用表格的程序
代码
$(
'
#tt
'
).datagrid({
title: ' 订购鉴权依赖设置 ' ,
iconCls: ' icon-save ' ,
width: 500 ,
height: 200 ,
nowrap: false ,
striped: true ,
collapsible: true ,
url: ' ${basepath}simulation/simulation.do?method=yilai ' ,
remoteSort: false ,
idField: ' id ' ,
frozenColumns:[[
{field: ' ck ' ,checkbox: true },
{title: ' id ' ,field: ' id ' ,width: 80 }
]],
columns:[
[
{title: ' 产品编号1 ' ,field: ' key ' ,width: 160 },
{title: ' 产品编号2 ' ,field: ' value ' ,width: 160 }
]
],
rownumbers: true
// toolbar:[{
// id:'btncut',
// text:'删除',
// iconCls:'icon-cut',
// handler:function(){
// alert('del')
// }
// }]
});
});
title: ' 订购鉴权依赖设置 ' ,
iconCls: ' icon-save ' ,
width: 500 ,
height: 200 ,
nowrap: false ,
striped: true ,
collapsible: true ,
url: ' ${basepath}simulation/simulation.do?method=yilai ' ,
remoteSort: false ,
idField: ' id ' ,
frozenColumns:[[
{field: ' ck ' ,checkbox: true },
{title: ' id ' ,field: ' id ' ,width: 80 }
]],
columns:[
[
{title: ' 产品编号1 ' ,field: ' key ' ,width: 160 },
{title: ' 产品编号2 ' ,field: ' value ' ,width: 160 }
]
],
rownumbers: true
// toolbar:[{
// id:'btncut',
// text:'删除',
// iconCls:'icon-cut',
// handler:function(){
// alert('del')
// }
// }]
});
});
要注意生成的数据的格式,是标准的JSON的格式。
将struts所使用的action配置到struts-config.xml中
在Action中调用的方法的内容如下:
代码
/**
* 依赖性设置
*
* @param map
* @param form
* @param req
* @param res
* @return
* @throws Exception
*/
public ActionForward huchi(ActionMapping map, ActionForm form,
HttpServletRequest req, HttpServletResponse res) throws Exception {
List < PropertyBean > l = simulationBO.propForGrid( " huchi " );
JSONArray jsonArray = JSONArray.fromObject(l);
String baseStr = " {\ " total\ " :1,\ " rows\ " : " + jsonArray.toString()
+ " } " ;
outJsonUTFString(res, baseStr);
return null ;
}
* 依赖性设置
*
* @param map
* @param form
* @param req
* @param res
* @return
* @throws Exception
*/
public ActionForward huchi(ActionMapping map, ActionForm form,
HttpServletRequest req, HttpServletResponse res) throws Exception {
List < PropertyBean > l = simulationBO.propForGrid( " huchi " );
JSONArray jsonArray = JSONArray.fromObject(l);
String baseStr = " {\ " total\ " :1,\ " rows\ " : " + jsonArray.toString()
+ " } " ;
outJsonUTFString(res, baseStr);
return null ;
}
注意返回的值的内容,编码格式为UTF-8,看一下outJsonUTFString方法
代码
/**
* dengwei add JSON数据输出
*
* @param response
* @param json
*/
private void outJsonUTFString(HttpServletResponse response, String json) {
// response.setContentType("text/javascript;charset=UTF-8");
response.setContentType( " text/html;charset=UTF-8 " );
try {
outString(response, json);
} catch (Exception e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
}
* dengwei add JSON数据输出
*
* @param response
* @param json
*/
private void outJsonUTFString(HttpServletResponse response, String json) {
// response.setContentType("text/javascript;charset=UTF-8");
response.setContentType( " text/html;charset=UTF-8 " );
try {
outString(response, json);
} catch (Exception e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
}
使用response的输出返回给调用的页面
代码
//
输出json格式数据
private void outString(HttpServletResponse response, String str) {
try {
PrintWriter out = response.getWriter();
// out.write(str);
out.println(str);
out.flush();
out.close();
} catch (IOException e) {
e.printStackTrace();
}
}
private void outString(HttpServletResponse response, String str) {
try {
PrintWriter out = response.getWriter();
// out.write(str);
out.println(str);
out.flush();
out.close();
} catch (IOException e) {
e.printStackTrace();
}
}
其中使用net.sf.json.JSONArray来处理生成的json对象,将list中的内容格式化成页面上需要返回的json格式,当然也可以使用其它的工具类来完成。
下面把完整的jsp页面和要使用的几个类文件的源码贴上来吧
<%@ page language="java" contentType="text/html; charset=UTF-8" pageEncoding="UTF-8"%> <%@ taglib uri="http://struts.apache.org/tags-bean" prefix="bean" %> <%@ taglib uri="http://struts.apache.org/tags-html" prefix="html" %> <%@ taglib uri="http://struts.apache.org/tags-logic" prefix="logic" %> <% String path = request.getContextPath(); String basePath = request.getScheme()+"://"+request.getServerName()+":"+request.getServerPort()+path+"/"; request.setAttribute("basepath",basePath); %> <!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd"> <html:html> <head> <base href="<%=basePath%>"> <meta http-equiv="Content-Type" content="text/html; charset=UTF-8"> <title>依赖设置</title> <link rel="stylesheet" type="text/css" href="${basepath}resources/default.css"/> <link rel="stylesheet" type="text/css" href="${basepath}resources/themes/default/easyui.css"/> <link rel="stylesheet" type="text/css" href="${basepath}resources/themes/icon.css"> <script type="text/javascript" src="${basepath}resources/jquery-1.4.2.min.js"></script> <script type="text/javascript" src="${basepath}resources/jquery.easyui.min.js"></script> <script type="text/javascript" src="${basepath}resources/jquery[1].json-1.3.min.js"></script> <script> $(function(){ $('#tt').datagrid({ title:'订购鉴权依赖设置', iconCls:'icon-save', width:500, height:200, nowrap: false, striped: true, collapsible:true, url:'${basepath}simulation/simulation.do?method=yilai', remoteSort: false, idField:'id', frozenColumns:[[ {field:'ck',checkbox:true}, {title:'id',field:'id',width:80} ]], columns:[ [ {title:'产品编号1',field:'key',width:160}, {title:'产品编号2',field:'value',width:160} ] ], rownumbers:true // toolbar:[{ // id:'btncut', // text:'删除', // iconCls:'icon-cut', // handler:function(){ // alert('del') // } // }] }); }); function setProp(){ $('#formId').form('submit',{ url:"${basepath}simulation/simulation.do?method=modifyYilai", onSubmit:function(){}, success:function(data){ eval('data='+data); if (data.success){ $.messager.alert('操作提示','操作成功!','info'); $('#tt').datagrid('reload'); $('#formId').form('clear'); } else { $.messager.alert('错误',data.msg,'error'); } } }); } </script> </head> <body> <html:form action="/simulation/simulation.do?method=setSimulation" styleId="formId"> <div align="center"> <table> <tr> <td align="left">产品编号1:</td> <td><input id="pbkey" type="text" name="pb.key" value=""/></td> </tr> <tr> <td align="left">产品编号2:</td> <td align="left"><input id="pbvalue" type="text" name="pb.value" value=""/></td> </tr> </table> </div> <div style="text-align:center;padding:5px;"> <a href="javascript:void(0)" onclick="setProp()" id="btn-save" class="easyui-linkbutton" icon="icon-ok">设置</a> </div> <div align="center"> <table id="tt"></table> </div> </html:form> </body> </html:html>
要使用的struts文件就自己配置一下吧
<action-mappings> <action attribute="SimulationForm" input="/index.jsp" name="SimulationForm" path="/simulation/simulation" parameter="method" scope="request" type="org.springframework.web.struts.DelegatingActionProxy"> <forward name="index" path="/views/vsopsimulation/index.jsp" /> <forward name="crmindex" path="/views/crmsimulation/index.jsp" /> </action> </action-mappings>
接下来是Action中的代码可以在上边找一下
然后是逻辑类中的代码文件
public List<PropertyBean> propForGrid(String type){ List<PropertyBean> l = new ArrayList<PropertyBean>(); String value = ""; if("yilai".equals(type)){ value = ConfigParser.get("yilai_list"); }else{ value = ConfigParser.get("huchi_list"); } if(value.length()>0){ String[] str = value.split(";"); for (int i = 0; i < str.length; i++) { String[] kvStr = str[i].split(","); PropertyBean prob = new PropertyBean(); prob.setId(i); prob.setKey(kvStr[0]); prob.setValue(kvStr[1]); l.add(prob); } } return l; }
好了,看一下运行的效果吧,这个工程中没有加上分页,因为数据量不大。
如果有需要源码的我可以把源码分享出来,下一步会完成在产品编号1和产品编号2中添加值后在列表中动态显示。
