Ajax数据表单序列化防止双重提交

如果我快速按下触发点击通话的按钮,我就会制作我的表格以防止双重暗杀。我尝试在成功后禁用按钮,但它仍然发送两次。这是我的代码:

<script>
$(document).ready(function () {

    $("button#rezerva").click(function () {
        var chkArray = [];
        $(".table:checked").each(function () {
            chkArray.push($(this).attr("id"));
        });
        var selected;
        selected = chkArray.join(",");
        $.ajax({
            type: "POST",
            url: "http://rezerv.city/engine/app/add_rezervare.php?mese=" + selected,
            data: $("form#formular_rezervare").serialize(),
            success: function (data) {
                switch (data) {
                    case "nume_error":
                        $(".msg").html("<p>Vă rugăm completați numele</p>").fadeIn("slow");
                        break;
                    case "tel_error":
                        $(".msg").html("<p>Vă rugăm completați telefonul</p>").fadeIn("slow");
                        break;
                    case "email_error":
                        $(".msg").html("<p>Vă rugăm completați un email valid</p>").fadeIn("slow");
                        break;
                    case "tel_numar":
                        $(".msg").html("<p>Numarul de telefon trebuie sa contina 10 cifre</p>").fadeIn("slow");
                        break;
                    case "adaugat":
                        $('#rezerva").attr('disabled', 'disabled')
                        var ora = document.getElementById("timepicker1").value;
                        var zi_aleasa = document.getElementById("zi").value;
                        var tip = document.getElementById("tipp").value;
                        var id_local = document.getElementById("id_local").value;
                        $("#filtru_zi").load("http://rezerv.city/select_tip_rezervare.php?zi=" + zi_aleasa + "&tip=" + tip + "&id=" + id_local);
                        $(".succes").html("<p class=\'text-center\'>Ati rezervat masa <b>" + selected + "</b> in data de <b>" + zi_aleasa + "</b> la ora <b>" + ora + "</b></p><p class=\'text-center\'><button class=\'btn btn-default\' type=\'button\' id=\'inchide\'>Închide</button></p>").fadeIn("slow");
                        break;
                    default:
                        alert("A aparut o eroare. Va rugam incercati mai tarziu.");
                }
            },
        });
    });
});
</script>

我建议将处理程序从onclick更改为onsubmit并使用e.preventDefault。

$("#formid").on('submit', function(e){
    e.preventDefault();
    //the rest of your code
});

我会将事件监听器绑定到表单的提交事件而不是按钮的单击。我知道您在问题中没有提出要求,但绑定到表单提交活动会提供更好的用户体验,因为您的用户仍然可以在表单中输入提交它。

现在,关于您的问题,看起来问题在于您使用Ajax。即使您的ajax请求尚未返回,表单仍会提交。你需要做的是:

$(function () {
    $('#myform').submit(function (e) {
          e.preventDefault();

          // continue on with your business logic
    });
});

当然,click事件的工作方式相同,因此如果您需要绑定到提交按钮的点击事件,您也可以执行以下操作:

$(function () {
    $("button#rezerva").click(function (e) {
        e.preventDefault();

        // continue on with business logic
    });
});

您必须在点击提交时立即停用

selected = chkArray.join(",");
 $('#rezerva"]').attr('disabled','disabled')//ADD THIS
 $.ajax({
            type: "POST",
            url: "http://rezerv.city/engine/app/add_rezervare.php?mese="+selected,
            data: $("form#formular_rezervare").serialize(),
            success: function(data){ 
            switch(data) {
                    case "nume_error":
                         $(".msg").html("<p>Vă rugăm completați numele</p>").fadeIn("slow");
 $('#rezerva"]').attr('enable','enable')//ADD THIS
                        break;
