jquery - jQuery 验证 onblur

Question

我正在尝试让 jQuery 验证在我正在创建的网页上运行。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，因为我隐藏并展示它们可以提供更好的用户体验。

每当我尝试提交页面以及添加单个字符（当文本框需要 2 个或更多字符时）时，我都会让插件按我想要的方式工作，但是我也希望验证发生在 onblur 上。如果他们没有满足验证条件，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。

谁能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 %>:
                {
                    required: true,
                    minlength: 2
                }
                ,
                <%=txtMobileNumber.UniqueID %>:
                {

Answer 1

潜水员丹是对的

$('form').validate({
    onfocusout: function (element) {
        $(element).valid();
    },
    rules: {
        name: 'required',
        from: 'required'

    },
    messages: {
        name: 'Please enter your firstname',
        from: 'Please enter where are you from'
    }
});

Answer 2

我在 docos 中看不到任何可以做到这一点的东西。我能想到的唯一其他方法是。

$('#field1, #field2, #field3').blur(function(){
    validator.validate()
});

Answer 3

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'
        }
    });

Answer 4

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'
    }
});

Answer 5

Thia 代码不会在 keyup 上触发验证，但在模糊“失去焦点”时会触发验证，一旦用户开始编辑字段，验证消息就会消失。在此参考文献中找到更有趣的其他自定义： https ://jqueryvalidation.org/category/plugin/

$('#frm').validate({
            onkeyup: false,
            focusCleanup: true
        });

Answer 6

尝试：

onkeyup: function (element, event) {

 $(element).valid();
 // your code
}
