1.少量数据的请求方式，直接在data中罗列出来
$.ajax({
type : "post",
url : "addOrgUnit",//后台action
contentType : 'application/x-www-form-urlencoded; charset=utf-8',
data : "code=" + code + "&deptname=" + deptname + "&typeid="
+ typeid + "&areaname=" + areaname + "&areaid=" + areaid,//传参
success : function(msg) {//成功返回
$.messager.alert("操作提示",msg,"info",function(){
location.href = "orgUnits";
});
},
error : function() {//返回失败
$.messager.alert("操作提示","连接失败！","error");
}
});
2.大量数据的请求方式，form表单的序列化
{
$.ajax({
cache:true,
type:"post",
url:"addexpert",
data:$('#addPJZJ_form').serialize(),
async:false,
error:function(request){
$.messager.alert("操作提示","error");
},
success:function(msg){
$.messager.alert("操作提示",function(){
document.getElementById("addPJZJ_form").reset();//表单重置
location.href="houtai/expertUser";
// refresh();
});
// alert("您的专家信息已添加成功，请审核");
}
});
}
}
});
3.json数据的请求方式，dataType为json
$.ajax({
type:"post",
url:"toTabexpert",
data:"expertid="+expertid,
dataType : "json",
error:function(){
$.messager.alert("操作提示","error");
},
success : function(data) {
var result = eval(data);//后台返回的json格式的数据
$("#info").html("<table bgcolor='#CCCCC' border='0' cellpadding='5' cellspacing='1'><tbody font-size='12px'><tr bgcolor='#ffffff'><td width='110'>1、姓 名</td><td align='left'>"+result[0].expertname+"</td>" +
"<td>"+
"</tbody></table>");
$('#showExpert').dialog('open');
}
});
后台json格式的数据
@RequestMapping(value = "toTabexpert")
public @ResponseBody String toTabexpert(HttpServletRequest request,
HttpServletResponse response,int expertid) {
String sql = "from TabExpert te where te.expertid='" + expertid + "'";
List<TabExpert> tabExperts = tabExpertSercive
.getTabExpertListByHql(sql);
List<TabExpert> listExpertinfo = new ArrayList<TabExpert>();
for (int i = 0; i < tabExperts.size(); i++) {
TabExpert tabExpert = new TabExpert();
tabExpert.setExpertname(tabExperts.get(i).getExpertname());
listExpertinfo.add(tabExpert);
}
net.sf.json.JSONArray jsonArray = net.sf.json.JSONArray
.fromObject(listExpertinfo);
String jsonExperts = jsonArray.toString();
System.out.println("sfdsf" + jsonArray);
return jsonExperts;
}
