我的表单中有一个文本框，只有在空或包含11位数字时才能验证。 我尝试了在互联网上找到的所有解决方案但没有任何反应。
<script type="text/javascript">
$(document).ready(function() {
$('#ctl00_CPH1_tax_id').attr("placeholder", "1234567890");
$('#ctl00_CPH1_citizen_id').attr("placeholder", "12345678901");
$('#ctl00_CPH1_e_posta').attr("placeholder", "ahmet.mehmet@sirket.com.tr");
//var isbp = $('#ctl00_CPH1_IsBP');
var name = $('#ctl00_CPH1_name').val();
var code = $('#ctl00_CPH1_code').val();
var dropdownlist2 = $('select:first');
var tax_id = $('#ctl00_CPH1_tax_id').val();
var citizen_id = $('#ctl00_CPH1_citizen_id').val();
var email1 = $('#ctl00_CPH1_e_posta').val();
var isbp = $('input[type=checkbox]:first');
var dropdownlist1 = $('select:last');
var isactive = $('input[type=checkbox]:last');
//var dropdownlist1 = $('#ct100_CPH1_DropDownList1');
var tax_id_check = /^\d{10}$/.test(tax_id);
var citizen_id_check = /^$|^\d{11}$/.test(citizen_id);
var email1_check = /^[a-zA-Z0-9._]+@([a-zA-Z0-9.]|[a-zA-Z0-9]+\-[a-zA-Z0-9.])+\.[a-zA-Z]{2,6}$/.test(email1);
dropdownlist1.attr("disabled", "disabled");
isactive.attr("disabled", "disabled");
$(isbp).click(function(e) {
if (isbp.is(':checked')) {
dropdownlist1.removeAttr("disabled");
isactive.removeAttr("disabled");
}
else {
isactive.attr("disabled", "disabled");
dropdownlist1.attr("disabled", "disabled");
}
});
$("#ctl00_CPH1_Button1").click(function(e) {
//console.log(drop2);
//var name_status = /^[a-zA-Z][a-zA-Z]*$/.test(name);
//var code_status = /^[a-zA-Z][a-zA-Z]*$/.test(code);
//var IsBP = $('#ctl00_CPH1_IsBP');
//if (name.length < 3 || name_status == false) {
// e.preventDefault();
// alert('İsim sadece karakterlerden oluşmalı ve en az iki karakter olmalı!');
//}
//if (code.length < 3 || code_status == false) {
// e.preventDefault();
// alert('Soyisim sadece karakterlerden oluşmalı ve en az iki karakter olmalı!');
//}
if (name.length == 0) {
e.preventDefault();
alert("İsim girilmedi!");
}
if (code.length == 0) {
e.preventDefault();
alert("Şirket Kodu girilmedi!");
}
if (dropdownlist2.val() == 0) {
e.preventDefault();
alert("Ülke seçilmedi!");
}
if (citizen_id.length != 0) {
e.preventDefault();
alert("Vatandaşlık numarası onbir haneli olmalı!");
}
if (tax_id.length == 0) {
e.preventDefault();
alert("Vergi numarası girilmedi!");
}
else if (!tax_id_check) {
e.preventDefault();
alert("Vergi numarası on haneli olmalı!");
}
if (email1 != "" && !email1_check) {
e.preventDefault();
alert("E-Posta geçerli değil!");
}
if (isbp.is(':checked') && dropdownlist1.val() == 0) {
e.preventDefault();
alert("İş ortağı tipi seçilmedi!");
}
});
});
这是我的脚本，aspx如下：

我尝试了jquery旧版本，如1.8.3，它是稳定的而不是1.9.1 还有jquery.validate。 当我在chrome上运行代码并在控制台上检查元素时，一切都正常运行。 但我的代码没有显示任何警报。 “==”但可以“！=”或“＆gt;”不。 提前致谢！ 不工作的文本框是e_mail和citizen_id。其他文本框正常工作。
答案 0 :(得分：2)
将ASP.NET验证程序与正则表达式一起使用
"(\d{11})?"
<asp:RegularExpressionValidator ControlToValidate="citizen_id"
ValidationExpression="(\d{11})?" runat="server"
Text="Must be 11 digits or empty" />
如果文本框“citizen_id”不是“”或11位数字，这将阻止回发。
