1、第一種方式通過bean,後臺需封裝成json數據格式,前臺paseJSON();
public void checkCode() {
ResponseMessage rm = new ResponseMessage(true,null);
String hql = "from TblWrPeople t where t.wrPeopleCode='"+code+"' and t.delFlag='"+Constants.DELFLAGA+"'";
List<TblWrPeople> tblWrPeopleList = (List<TblWrPeople>)this.workResService.find(hql);
if (tblWrPeopleList != null && tblWrPeopleList.size() > 0) {
rm.setSuccess(false);
rm.setErrorMsg("數據庫中已存在該代號,請重新錄入");
this.responseAJAX(JSONObject.fromObject(rm).toString(), getResponse());
}
}
前臺獲取:
function checkCode() {
var code = $("#wrPeopleCode").val();
$.post('workRes_checkCode.action',{"code":code},function(result){
result = $.parseJSON(result);
if (result.success == false){
alert(result.errorMsg);
$("#wrPeopleCode").val('');
}
});
}
2、後臺直接返回一個String類型的字符串,前臺的話不再需要parseJSON,直接獲取result即可;
