Здравствйте. Помогите, пожалуйста, решить проблему.
На странице есть ajax запрос
function popBox(num1, num2) {
x = confirm('Are you sure? ' + num1);
if (x == true) {
var xhr = new XMLHttpRequest();
xhr.open("POST", "userChangeTariff?tariffId=" + num1 + "&contractNumber=" + num2, false);
xhr.send();
}
}
В приложении есть сервлет
@RequestMapping(value = "/userChangeTariff", method = RequestMethod.POST)
public String changeTariff(HttpServletRequest request, Locale locale, Model model)
{
String tariffId = (String) request.getAttribute("tariffId");
String contractNumber = (String) request.getAttribute("contractNumber");
System.out.println(tariffId + " " + contractNumber);
int tariffID = Integer.valueOf(tariffId);
Contract contract = contractService.getContractByNumber(contractNumber);
Tariff tariff = tariffService.getEntityById(tariffID);
contract.setTariff(tariff);
contractService.updateEntity(contract);
return "user/userTariffs";
}
Но почему-то ajax не возбуждает сервлет. Почему, понять не могу. Что я делаю не так?
