[英]Validation using Ajax call not working
我是Ajax和Jquery的新手,我有一個表單,其中有一個DepositAccountNumberId
文本框,其值存儲在一個用於驗證的隱藏字段中。
DepositAccountNumberId TextBox的OnBlur
事件應發出引導框alert ("This Account Number has been Suspended")
。 我已經發布了以下代碼:
用於CheckAccountSuspension()的Javascript函數
var exist = true; function checkAccountSuspension() { var accountNumberId = $('#DepositAccountNumberIdHiddenField').val(); // alert(accountNumberId); if (accountNumberId == "") { // } else { try { var url = '/WebMethods/AccountDetails.asmx/IsAccountSuspended'; var d = { accountNumberId: accountNumberId }; //var jqXhr = $.post(url, d); //jqXhr.done(function(data) { $.post(url, d, function (data) { if (data) { var ret = data.d; if (ret) { $('#DepositAccountNumberIdHiddenField').val(accountNumberId); exist = true; } else { $('#DepositAccountNumberIdHiddenField').val(''); bootbox.alert("This Account Has been Suspended"); exist = false; } } }).fail(function() { $('#DepositAccountNumberIdHiddenField').val(''); }); } catch (e) { bootbox.alert('Error: ' + e); } }
網絡方法
[WebMethod(EnableSession = true)]
public bool IsAccountSuspended(string accountNumberId)
{
int officeId = OfficeId;
return BusinessLayer.Transactions.Transactions.IsAccountSuspended(officeId, accountNumberId.ToLong());
}
IsAccountSuspended在業務層中
public static bool IsAccountSuspended(int officeId, long accountNumberId)
{
if (accountNumberId <= 0)
{
return false;
}
return DatabaseLayer.Transactions.Transactions.IsAccountSuspended(officeId,accountNumberId);
}
IsAccountSuspended在數據庫層
public static bool IsAccountSuspended(int officeId, long accountNumberId)
{
if (accountNumberId <= 0)
{
return false;
}
var sql = "SELECT * FROM deposit.is_suspended(@AccountNumberId::bigint);";
using (var command = new NpgsqlCommand(sql))
{
command.Parameters.AddWithValue("@AccountNumberId", accountNumberId);
using (var table = DBOperations.GetDataTable(command))
{
if (table.Rows.Count >= 1)
{
return true;
}
return false;
}
}
}
驗證不起作用。不會調用ajax來檢查帳戶是否被暫停。請幫助。
嘗試使用$.post
方法:
var exist = true;
function checkAccountSuspension() {
var accountNumberId = $('#DepositAccountNumberIdHiddenField').val();
// alert(accountNumberId);
if (accountNumberId == "") {
//
} else {
try {
var url = '/WebMethods/AccountDetails.asmx/IsAccountSuspended';
var d = {accountNumberId: accountNumberId};
var jqXhr = $.post(url, d);
jqXhr.done(function (data) {
if (data) {
var ret = data.d;
if (ret) {
$('#DepositAccountNumberIdHiddenField').val(accountNumberId);
exist = true;
} else {
$('#DepositAccountNumberIdHiddenField').val('');
bootbox.alert("This Account Has been Suspended");
exist = false;
}
}
}).fail(function () {
$('#DepositAccountNumberIdHiddenField').val('');
});
} catch (e) {
bootbox.alert('Error: ' + e);
}
}
}
$('#DepositAccountNumberTextBox').on('blur', function () {
checkAccountSuspension();
});
在JQuery中沒有像ajaxPost這樣的方法。 在其位置使用$ .Post。
try {
var url = '/WebMethods/AccountDetails.asmx/IsAccountSuspended';
var d = { accountNumberId: accountNumberId };
$.post(url,d,function(data){
if (data) {
var ret = data.d;
if (ret) {
$('#DepositAccountNumberIdHiddenField').val(accountNumberId);
exist = true;
}
else {
$('#DepositAccountNumberIdHiddenField').val('');
bootbox.alert("This Account Has been Suspended");
exist = false;
}
}
}).error(function() {
$('#DepositAccountNumberIdHiddenField').val('');
})
}
catch (e) {
bootbox.alert('Error: ' + e);
}
這就是它的工作方式。
就像上面的一些專家所說,有關postAjax和$ .post的使用。 在項目的各處,以前的開發人員都將其用作postAjax。 我實際上是在隱藏字段中再次傳遞了空值。 此代碼有效。
var exist = true; function checkAccountSuspension() { var accountNumberId = $('#DepositAccountNumberIdHiddenField').val(); if (accountNumberId == "") { // } else { try { var url = '/WebMethods/AccountDetails.asmx/IsAccountSuspended'; var d = { accountNumberId: accountNumberId }; //$.post(url, d, function (data) { var jqXhr = ajaxPost(url, d, true); jqXhr.done(function (data) { var ret = data.d; if (!ret) { $('#DepositAccountNumberIdHiddenField').val(accountNumberId); exist = true; } else { //$('#DepositAccountNumberIdHiddenField').val(''); // bootbox.alert("<b class='text-red'>Suspended Account</b> <br/>This Account has been Suspended."); swal({ title: "Suspended Account!", text: "This Account is Suspended", type: "error", confirmButtonText: "OK", imageSize: "20x20" }); exist = false; resetAllInputs(); } }).fail(function (ex) { bootbox.alert("Requested process fail to execute"); //$('#DepositAccountNumberIdHiddenField').val(''); }); } catch (e) { bootbox.alert('Error: ' + e); } } }
