在一个 MVC3 应用程序中，我有一个呈现两个 Ajax 部分视图的视图：一个创建部分视图和一个列表。在创建局部视图中，我尝试在 OnBegin 事件上触发客户端验证，但这不会发生。
当我强制错误时，我得到的错误消息是模型注释中指示的，而不是我在称为 OnBegin 的验证函数中定义的错误消息（例如：
将活动地点留空，我得到“需要活动地点”（注释）而不是“它发生在哪里？ ”（FieldsValidation 函数），
对于事件描述，我得到“需要事件描述”（注释）而不是“告诉我们某事！ ”（FieldsValidation 函数）
并且验证摘要消息是“创建时出错。请在更正后重试。 ”而不是“保存失败。请更正错误并重试。 ”（FieldsValidation 函数）。
我试图在 FieldsValidation 函数中放置一个断点，但从未达到。为了确保，我还尝试调用 OnBegin 显示警报的函数（测试后我恢复了对 FieldsValidation 函数的原始调用）：
function toDoOnBegin() { alert("This is onBegin"); }
警报永远不会显示！
如果所有字段都正确填写，则事件被正确创建并显示在事件列表（另一个部分视图）中。唯一的问题是函数调用 OnBegin。
请解释我做错了什么，我是否错过了包含某些内容或其他内容？
真的谢谢你。
