ajax - MVC3 与 Ajax 部分 View - 未执行 OnBegin 验证

Question

在 MVC3 应用程序中，我有一个 View 呈现两个 Ajax 部分 View :一个创建部分 View 和一个 ListView 。在创建部分 View 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消息，而不是我在名为 OnBegin 的验证函数中定义的消息(例如:

• 将事件地点留空，我得到“事件地点是必需的”(注释)，而不是“它在哪里发生？”(FieldsValidation函数)，

• 对于事件描述，我得到“需要事件描述”(注释)，而不是“告诉我们有关它的信息!”(FieldsValidation 函数)

• 验证摘要消息显示“创建时出错。请更正后重试。”而不是“保存失败。请更正错误并重试。” (FieldsValidation 函数))。

我尝试在 FieldsValidation 函数中设置断点，但从未到达。 为了确定，我还尝试调用 OnBegin 一个显示警报的函数(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!

如果所有字段均正确填写，则事件将正确创建并显示在事件列表(另一个部分 View )中。问题出在函数调用 OnBegin 上。

请解释一下我做错了什么，我是否错过了包含某些内容或者还有什么？

真心感谢。

Answer 1

Here is the answer: (非常感谢布罗克艾伦)

If you are doing your own client-side validation then you should remove jquery.validate.unobtrusive.min.js. This is MVC's client side validation code and they will conflict if both are using jquery.validate.

希望这对其他人也有帮助。
