今天使用$.getJSON(url,null,function call(data){});获取数据：
前台js代码：
<script type="text/javascript">
//<![CDATA[
function convertUrl(url){
var timestamp = (new Date()).valueOf();
if(url.indexOf("?")>=0){
url = url+"&t="+timestamp;
}else{
url = url+"?t="+timestamp;
}
return url;
}
$(function(){
var newUrl01 = "/html/school/schoolTJSchoolWeb.do?sch_hot=3";
$.getJSON(convertUrl(newUrl01),null,function call(data){
var myTitle="";
for(var i=0; i<$(data).length-1 ;i++){
var otherObj = $(data).get(i+1);
if(otherObj.sch_name.length>21){
myTitle +="<li id='sch_name'><a href='/html/school/viewInfoSchoolWeb.do?sch_id="+otherObj.sch_id+"'>"+otherObj.sch_name.substring(0,21)+'..'+"</a></li>";
}else{
myTitle +="<li id='sch_name'><a href='/html/school/viewInfoSchoolWeb.do?sch_id="+otherObj.sch_id+"'>"+otherObj.sch_name+"</a></li>";
}
}
$("#school_ul01").html(myTitle);
});
var newUrl = "/html/school/adSchoolWeb.do";
$.getJSON(convertUrl(newUrl),null,function call(data){
var myTitle="";
for(var i=0; i<$(data).length ;i++){
var otherObj = $(data).get(i);
myTitle +="<li><a href='#'><img width='220' height='70' src='/"+otherObj.AD_FILE_PATH+"' alt='广告' /></a></li>";
}
$("#ad_ul").html(myTitle);
});
});
//]]>
</script>
前台jsp代码：
<html>
<head>
<title></title>
</head>
<body>
<div>
<ul id="school_ul01">
<li></li>
</ul>
<ul id="ad_ul">
<li></li>
</ul>
</div>
</body>
</html>
后台java代码：
public void schoolTJ() throws Exception{
HttpServletResponse response = ServletActionContext.getResponse();
HttpServletRequest request = ServletActionContext.getRequest();
String sch_hot = request.getParameter("sch_hot");
List<DragonSchool> schoolList = (List<DragonSchool>) this.webDragonSchoolService.list("select * from dragon_school where SCH_HOT ='"+sch_hot+"' limit 0,10", DragonSchool.class);
Gson gson = new Gson();
String schoolListToJson = gson.toJson(schoolList);
response.setCharacterEncoding("utf-8");
response.getWriter().write(schoolListToJson);
response.getWriter().close();
}
public void ad() throws Exception{
HttpServletResponse response = ServletActionContext.getResponse();
List adList = webDragonAdvertisingService.webList(pager, "4", null, 9);
Gson gson = new Gson();
String adListToJson = gson.toJson(adList);
response.setCharacterEncoding("utf-8");
response.getWriter().write(adListToJson);
response.getWriter().close();
}
