ajax提交异步验证

简单实用的ajax异步校验代码

jqueyr代码：

function submitPriceInfo(){

var price = $("#price").val();

var amount = $("#amount").val();

var pbillId = $("#pbillId").val();

var curentId = "$!enterprise.id";

var billId = "$!tTraPbill.enterpirse.id";

if(curentId==billId){

alert("不能给自己报价！！");

}else{

$.ajax({

type : "post",

url : "$!webPath/usercenter/delegateManage/submitPprice.htm",

data : {price:price,amount:amount,pbillId:pbillId},

async : false,

success : function(data){

var codes = jQuery.parseJSON(data);

if(codes.code=="0"){

alert("提交不成功！");

}else{

if(codes.code=="1"){

alert("报价提交成功！");

if(confirm("点击确定刷新后将显示委托采购页面!")){

document.location.href="$!webPath/itTraPbillInfo/list.htm";

}

}else{

if(codes.code="2"){

document.location.href="$!webPath/login.htm";

}

}

}

}

});

}

}

注：$!webPath为事先定义好的，为http://localhost:8080/项目名

控制层：

@RequestMapping("/submitPprice.htm")

@ResponseBody

public ResponseEntity<String> submitPprice(HttpServletRequest request,

HttpServletResponse response) {

String json = "";

String price = request.getParameter("price");

String amount = request.getParameter("amount");

String pbillId = request.getParameter("pbillId");

TTraEnterprise enterprise = SecurityUserHolder.getCurrentTTraEnterprise();

if(enterprise==null){

json = "{\"code\":\"2\"}";

}else{

String enterpriseId = enterprise.getId();

TTraUser user = SecurityUserHolder.getCurrentUser();

String userId = user.getId();

TTraPprice traPprice = new TTraPprice();

traPprice.setEnterpriseId(enterpriseId);

traPprice.setPrice(Double.parseDouble(price));

traPprice.setAmount(Double.parseDouble(amount));

traPprice.setPbillId(pbillId);

traPprice.setAddUserId(userId);

SimpleDateFormat sdf = new SimpleDateFormat("yyyy-MM-dd HH:mm:ss");

String dateStr = sdf.format(new Date());

Date date = null;

try {

date = sdf.parse(dateStr);

} catch (ParseException e) {

// TODO Auto-generated catch block

e.printStackTrace();

}

traPprice.setAddTime(date);

traPprice.setStateFlag("0");

TTraPbill ttraPbill = itTraPbillService.getObjById(pbillId);

if(itTraPpriceService.save(traPprice)){

json = "{\"code\":\"1\"}";

if(ttraPbill.getStateFlag().equals("0")){

ttraPbill.setStateFlag("2");

}

if(ttraPbill.getApriceNum()==null || ttraPbill.getApriceNum()==0){

ttraPbill.setApriceNum(1l);

}else{

ttraPbill.setApriceNum(ttraPbill.getApriceNum()+1);

}

itTraPbillService.update(ttraPbill);

}else{

json = "{\"code\":\"0\"}";

}

}

HttpHeaders headers = new HttpHeaders();

headers.add("Content-Type", "application/text;charset=UTF-8");

return new ResponseEntity<String>(json, headers, HttpStatus.ACCEPTED);

}
