javascript - jQuery验证后，OnClick不起作用

我已经通过jquery给出了验证，该验证在单击按钮时效果很好。
但是，一旦我将所有数据填充到页面中，我的onClick就不会触发。我不知道为什么。请提出建议。

这是我的jQuery代码：

var ErrArr = [];
    $(document).ready(function () {
        $('#btnSave').click(function (e) {
            e.preventDefault();
            validateTitle();
            validateddl();
            validateTextBoxes();
            if (ErrArr.length > 0) {
                alert(ErrArr.join("\n"));
                ErrArr = [];
                return false;
            }
        });
        function validateTitle() {
            if ($("#ddlTitle").val() > "0") {
                if ($("#ddlTitle").val() == "1104" && $("#txtTitle").val() === "") {
                    ErrArr.push("Please enter the text in other title");
                }
            } else {
                ErrArr.push('Please select the title');
            }
        }
        function validateTextBoxes() {
            if ($("#txt_emp_fname").val() === "") {
                ErrArr.push('First name is required');
            }
            if ($("#txt_emp_mname").val() === "") {
                ErrArr.push('Middle name is required');
            }
            if ($("#txt_emp_lname").val() === "") {
                ErrArr.push('Last name is required');
            }

            if ($("#txtDateofJoin").val() === "") {
                ErrArr.push('Date of joining is required');
            }
            if ($("#txtReligion").val() === "") {
                ErrArr.push('Religion is required');
            }
            if ($("#txtBloodGroup").val() === "") {
                ErrArr.push('Blood group is required');
            }
            if ($("#txtPersonalEmail").val() === "") {
                ErrArr.push('Email Id is required');
            }
            if ($("#txtDtOfBirth").val() === "") {
                ErrArr.push('Date of birth is required');
            }
            if ($("#txtAt").val() === "") {
                ErrArr.push('Place of birth is required');
            }
            if ($("#txtTaluka").val() === "") {
                ErrArr.push('Taluka is required');
            }
            if ($("#txtPostOffice").val() === "") {
                ErrArr.push('Post office is required');
            }
            if ($("#txtDistrict").val() === "") {
                ErrArr.push('District is required');
            }
            if ($("#txtStatePersonal").val() === "") {
                ErrArr.push('State is required');
            }
            if ($("#txtDtMarriage").val() === "") {
                ErrArr.push('Date of Marriage is required');
            }
            if ($("#TxtPassportNo").val() === "") {
                ErrArr.push('Passport no is required');
            }
            if ($("#txtIdMark").val() === "") {
                ErrArr.push('Identification mark is required');
            }
        }
        function validateddl() {
            if ($("#ddlGender").val === "" || $("#ddlGender").val() == "0") {
                ErrArr.push('Please select the gender');
            }
            if ($("#ddlMaritalStatus").val === "" || $("#ddlMaritalStatus").val() == "0") {
                ErrArr.push('Please select the Marital Status');
            }
            if ($("#ddlNationality").val === "" || $("#ddlNationality").val() == "0") {
                ErrArr.push('Please select the Nationality');
            }
        }
    });

另请参阅按钮的aspx：-

<asp:Button ID="btnSave" CssClass="button" Text="Save" runat="server"
                    CausesValidation="true" onclick="btnSave_Click"
                    />

最佳答案

我建议您不要单击按钮，而要提交表单来验证：

$(document).ready(function () {
    $('#formID').on("submit",function (e) {
        // e.preventDefault(); // does not belong here
        validateTitle();
        validateddl();
        validateTextBoxes();
        if (ErrArr.length > 0) {
            e.preventDefault();// but here
            alert(ErrArr.join("\n"));
            ErrArr = [];
        }
    });
.
.

我认为这也意味着您应该将按钮设为“提交”按钮，并确保asp不添加click事件，因为它已由jQuery分配。
