ajax对action json串操作（可操作大量数据，常用于页面数据加载，如分页）

1：js

<scripttype="text/javascript">

$(document).ready(function(){

fn_Jump(1);

});

functionfn_Jump(gotoPage)

{

jQuery.ajaxSetup({cache:false});

varfirst="2012-1-1";

varlast="2013-12-31";

$.getJSON("testJsonAction!openByEmpId2.action",{first:first,last:last,currPage:gotoPage},function(json){

if(json.msg!="none"){

vardataString="";

dataString+="<TR>";

vardata=json.annList;

for(indexindata){

varobj=data[index];

dataString+="<TD>"+obj.fsContent+"</TD>";

}

dataString+="</TR>";

$("#dataList").append(dataString);

}

});

}

</script>

2:struts.xml文件中的配置

<!DOCTYPEstrutsPUBLIC

"-//ApacheSoftwareFoundation//DTDStrutsConfiguration2.0//EN"

"http://struts.apache.org/dtds/struts-2.0.dtd">

<struts>

<packagename="ann2"extends="json-default">

<actionname="testJsonAction"class="com.asia.home.cn.web.oa.TestJsonAction">

<resulttype="json"/>

</action>

</package>

</struts>

3:action

privateIRepAnnounceServiceannounceService;

privateList<RepAnnounce>annList;

privateStringmsg;

//按发布者查询公告

publicStringopenByEmpId2(){

try{

StringreadType=request.getParameter("readType");

StringfsEmpid="93b7f205-0134-1000-e000-35630a0000fa";

Stringauthor=UrlUtils.decode(request.getParameter("author"),

"utf-8");

Stringlast=request.getParameter("last");

Stringfirst=request.getParameter("first");

this.annList=announceService.findAnn(fsEmpId,newPage(),readType,

author,last,first);

}catch(Exceptione){

logger.info(e);

}

returnSUCCESS;

}

publicvoidsetAnnounceService(IRepAnnounceServiceannounceService){

this.announceService=announceService;

}
