ASP.NET MVC远程属性的方法参数总是传递null [英] ASP.NET MVC Remote attribute method parameter always passing null
问题描述
我有正在使用的远程验证属性,这个 AdvertiserNameAvailable
方法。
问题是,在 AdvertiserNameAvailable
是被称为无输入值传递给方法名称
参数。当我在调试进入的方法,我看到名称
参数始终是空
。
公共JsonResult AdvertiserNameAvailable(字符串名称)
{
返回JSON(一些自定义错误消息,JsonRequestBehavior.AllowGet);
} 公共类AdvertiserAccount
{
[需要]
[远程(AdvertiserNameAvailable,账户)]
公共字符串名称
{
得到;
组;
}
}
必须添加 [装订(preFIX =account.Name)]
公众的ActionResult AdvertiserNameAvailable([装订(preFIX =account.Name)]字符串名称)
{
如果(名称==Q)
{
返回JSON(假,JsonRequestBehavior.AllowGet);
}
其他
{
返回JSON(真,JsonRequestBehavior.AllowGet);
}
}
要找出你的preFIX,点击右键,请在您要验证输入检查元素。查找名称
属性:
<输入... ID =帐户名NAME =account.Name类型=文本值=>
I have this AdvertiserNameAvailable
method that is being used by Remote validation attribute.
The problem is that the AdvertiserNameAvailable
is being called without passing the input value to the method Name
parameter. When I enter in debug into the method, I see that the Name
parameter is always null
.
public JsonResult AdvertiserNameAvailable(string Name)
{
return Json("Some custom error message", JsonRequestBehavior.AllowGet);
}
public class AdvertiserAccount
{
[Required]
[Remote("AdvertiserNameAvailable", "Accounts")]
public string Name
{
get;
set;
}
}
Had to add [Bind(Prefix = "account.Name")]
public ActionResult AdvertiserNameAvailable([Bind(Prefix = "account.Name")] String name)
{
if(name == "Q")
{
return Json(false, JsonRequestBehavior.AllowGet);
}
else
{
return Json(true, JsonRequestBehavior.AllowGet);
}
}
To find out your prefix, right click and do inspect element on the input that you are trying to validate. Look for the name
attribute:
<input ... id="account_Name" name="account.Name" type="text" value="">
