在AJAX请求之前单击按钮进行客户端验证

问题描述：

我正在使用MVC 4，并且希望能够从表中的行集合中验证单个行，以确保正确输入字段并通过验证.

I'm using MVC 4 and I want to be able to validate a single row, from a collection of rows in a table, to ensure that the fields are entered correctly and pass validation.

属性已正确应用于模型，例如:

The Attributes are correctly applied on the model, for example:

[Required]
[MaxLength(50)]
[MinLength(5)]
public string Name {get; set;}

现在，在客户端-如何在调用AJAX方法之前启用客户端验证?

Now, on the client side - how do I enable client side validation before calling an AJAX method?

要增加更多的复杂性-我有一个按钮，您可以在其中动态向表添加一行，填写字段，最后单击update按钮，这将通过ajax执行POST.但是在发布这篇文章之前，我想在客户端验证该特定行.

To add more complications - I have a button where you can dynamically add a row to the table, fill out fields and finally hit the update button, which will do a POST via ajax. But before this post, I want to validate that particular row on client side.

我该怎么做?

谢谢

答

只要您在View中实现验证助手，这实际上就很简单.

As long as you're implementing the validation helpers in your View, this is actually really simple.

var form = $('#form');
$.validator.unobtrusive.parse(form);
form.validate();

if (form.valid()) {
    .... ajax stuff
}

在启动http请求之前，请致电上述内容，这将确保您的表单已通过验证.

Call the above before initiating the http request and it will make sure that your form is validated.
