我目前正在使用jquery validate plugin version 1.9.0，最新版本是1.11.0。当我迁移到最新版本时，表单上的错误检查不起作用。在阅读文档并查看examples on the site之后，我仍然无法找到解决方法。 （某些示例无法正常工作）
在我的代码中，我使用元验证类来指定字段是否有效并且希望将其保留在html中而不是在JS中指定它。
$("#report-listing-form").validate({
meta: "validate",
rules: {
recaptcha_response_field: {
required: true
}
},
errorContainer: {},
invalidHandler: function (event, validator) {
var errors = validator.numberOfInvalids();
if (errors) {
var message = (errors == 1)
? '1 invalid field.'
: errors + ' invalid fields.';
$("#err_report-listing-form").html(message).addClass("text-error");
}
},
submitHandler: function (form) {
alert('works');
}
});
我的代码示例在这里：
使用旧插件工作的元数据必须使用此插件

/**
* Sets the type of metadata to use. Metadata is encoded in JSON, and each property
* in the JSON will become a property of the element itself.
*
* There are three supported types of metadata storage:
*
* attr: Inside an attribute. The name parameter indicates *which* attribute.
*
* class: Inside the class attribute, wrapped in curly braces: { }
*
* elem: Inside a child element (e.g. a script tag). The
* name parameter indicates *which* element.
*
* The metadata for an element is loaded the first time the element is accessed via jQuery.
*
* As a result, you can define the metadata type, use $(expr) to load the metadata into the elements
* matched by expr, then redefine the metadata type and run another $(expr) for other elements.
*
* @name $.metadata.setType
*
* @example <p id="one" class="some_class {item_id: 1, item_label: 'Label'}">This is a p</p>
* @before $.metadata.setType("class")
* @after $("#one").metadata().item_id == 1; $("#one").metadata().item_label == "Label"
* @desc Reads metadata from the class attribute
*
* @example <p id="one" class="some_class" data="{item_id: 1, item_label: 'Label'}">This is a p</p>
* @before $.metadata.setType("attr", "data")
* @after $("#one").metadata().item_id == 1; $("#one").metadata().item_label == "Label"
* @desc Reads metadata from a "data" attribute
*
* @example <p id="one" class="some_class"><script>{item_id: 1, item_label: 'Label'}</script>This is a p</p>
* @before $.metadata.setType("elem", "script")
* @after $("#one").metadata().item_id == 1; $("#one").metadata().item_label == "Label"
* @desc Reads metadata from a nested script element
*
* @param String type The encoding type
* @param String name The name of the attribute to be used to get metadata (optional)
* @cat Plugins/Metadata
* @descr Sets the type of encoding to be used when loading metadata for the first time
* @type undefined
* @see metadata()

答案 0 :(得分：1)
1）拉出所有内联规则。他们显然不会这样工作......
class="{validate:{required:true, email: true}}"
请在.validate({...})内指定所有内容。不要忘记输入任何名称containing special characters within quotes。
rules: {
'listing-report-email': {
required: true,
email: true
},
// your other rules
},
工作演示：http://jsfiddle.net/4VP9X/4/ （运行jQuery 1.9.1和JQuery Validate 1.11.0）
2） maxWords规则要求包含additional-methods.js file。
3）不要忘记将代码包装在DOM ready事件处理函数中。
$(document).ready(function () {
$("#report-listing-form").validate({
// your rules & options
});
});
4）我也不知道meta: "validate"选项应该为您做什么。 It's not documented anyplace that I can find，您的代码似乎是work the same without it。
5） errorContainer: {},
您已将errorContainer:选项留空。如果这是故意的，你可以完全忽略这个选项。根据注释，将其替换为以下errorPlacement回调函数以禁止显示错误消息。然后设置.valid和.error CSS类的样式，以相应地突出显示有效和无效字段。
errorPlacement: function(error, element) {
return false; // will suppress all validation messages
},
