Regexvalidator 的 validaterequestmode=enabled 在 asp.net 中无法正常工作
Regexvalidator's validaterequestmode=enabled not working properly in asp.net
问：
注意：如果需要，可以查看我的项目（我遇到的问题在Login-Signup.aspx页面中。点击 这里 进入项目。
我在我的网络表单中添加了一些正则表达式验证器控件。我已将其属性validaterequestmode设置为enabled并检查了它。它曾经完美地工作，我的意思是，如果我的名字文本框中有一个空格，那么它在那个实例中会显示错误（不改变焦点），其他人也是如此。我在我的 js 中添加了一些函数，我什至不可能链接它们，现在当我运行页面时，除非我更改焦点，否则它不会验证输入。请帮我解决这个问题。
注意：我对正则表达式没有任何问题，这只是我所关心的validaterequestmode属性。
我在下面添加我的html代码： （用于注册视图）
//Donot uncomment any line. dare not uncommenting any line untill permission granted.
// Donot use the access key and the function verify() untill permission granted.
// set endpoint and your access key
var access_key = 'my_key';
var email_address;
var valid_format, smtp_check, disposable, mxfound, Urole;
function setmail() {
email_address = document.getElementById('TextBox11').value;
// document.getElementById('Label5').textContent = email_address;
verify();
}
// verify email address via AJAX call
function verify() {
$.ajax({
url: 'http://apilayer.net/api/check?access_key=' + access_key + '&email=' + email_address,
dataType: 'jsonp',
success: function validate(json) {
//Access and use your preferred validation result objects
console.log(json.format_valid);
console.log(json.smtp_check);
console.log(json.score);
console.log("disposable: " + json.disposable);
console.log(json.role);

document.getElementById("HFrole").innerHTML = json.role;
emailchck("HFformatvalid", "HFsmtpcheck", "HFdisposable", "HFmxfound", "HFrole");
}
});
}
function emailchck(id1, id2, id3, id4, id5) {
valid_format = document.getElementById(id1).innerText;

我有同样的问题，这就是我解决它的方式。
您的 RegularExpressionValidator 具有 ，这意味着它不会在客户端运行，而是在服务器端运行（从代码中）。runat="server"EnableClientScript="False"
您需要在代码中添加，特别是要重定向的位置，以防止向前移动并显示您在 RegularExpressionValidator 上设置的 。Page.IsValidErrorMessage
有关为什么 Page.isValid 会起作用的更多信息，请点击此处。
