我正在尝试在我正在创建的网页上运行jQuery验证。我有大约6个不同的字段集，其中包含页面的详细信息。我正在使用它，因为我隐藏并向他们展示提供更好的用户体验。
每当我尝试提交页面时，无论何时添加单个字符（当文本框需要2个或更多字符时），我都可以按照自己的意愿工作，但是我也希望验证能够在onblur上进行。如果他们没有达到验证条件，我想立即通知我的用户，以便他们可以立即修复它，而不必回来。
任何人都可以告诉我我需要做什么我正在使用* http://bassistance.de/jquery-plugins/jquery-plugin-validation/插件。
这是我到目前为止编写的jQuery代码：
$("#aspnetForm").validate({
rules: {
<%=txtFirstName.UniqueID %>:
{
required: true,
minlength: 2
}
,
<%=txtSurname.UniqueID %>:

我无法在docos中看到任何可以做到这一点的内容。我能想到的另一种方式是。
$('#field1, #field2, #field3').blur(function(){
validator.validate()
});
答案 2 :(得分：7)
您还可以使用验证器的元素调用。
$('form').validate({
onfocusout: function(element) {
this.element(element);
},
rules: {
name: 'required',
from: 'required'
},
messages: {
name: 'Please enter your firstname',
from: 'Please enter where are you from'
}
});

只需设置onkeyup = false
$('form').validate({
rules: {
name: 'required',
from: 'required'
},
onkeyup: false
,
messages: {
name: 'Please enter your firstname',
from: 'Please enter where are you from'
}
});

Thia代码不会触发验证onkeyup，但是模糊“丢失了 焦点“验证将会激活，一旦用户开始编辑该字段，验证消息将消失。在此ref上找到更有趣的其他自定义： https://jqueryvalidation.org/category/plugin/
$('#frm').validate({
onkeyup: false,
focusCleanup: true
});

尝试：
onkeyup: function (element, event) {
$(element).valid();
// your code
}
