How to Add JavaScript Validation/Attributes/Properties to Forms using Html.BeginForm()

To add a JavaScript validation, an attribute or properties to an HTML form generated in ASP.NET MVC using Html.BeginForm(), you can pass null values to the action and controller parameters to get the same result as Html.BeginForm():

Sample:

using (Html.BeginForm(null, null, FormMethod.Post, 
            new { onsubmit = "return validateForm();" }))
{
}
