Asp.net mvc - Html Submit button not sent with post?
提问by
As in the title. I use thismethod for allowing more than one submit button per form and more than one action to handle them.
如标题所示。我使用这种方法允许每个表单有多个提交按钮和多个操作来处理它们。
However - for some odd reason - all of a sudden my submit button doesn't get submitted with the form!? any reason why that would happen?
但是 - 出于某种奇怪的原因 - 突然间我的提交按钮没有与表单一起提交！？为什么会发生这种情况？
tested using IE, FF, Chrome - all latest
使用 IE、FF、Chrome 进行测试 - 都是最新的

Have you set the name on the input?
您是否在输入上设置了名称？
Form fields don't get sent unless you specify the "name" attribute.
除非您指定“名称”属性，否则不会发送表单字段。
<input type="submit" name="Delete" value="Delete" />
<input type="submit" name="Edit" value="Delete" />
EDIT: I see you're using buttons rather than submit. Which might be the problem.
编辑：我看到您正在使用按钮而不是提交。这可能是问题所在。
You need to have use inputs like this:
您需要使用这样的输入：
<input type="submit" value="Register" name="ActionRegister"/>
<input type="submit" value="Cancel" name="ActionCancel" class="cancel" />

The way I have done this before is I post my form to same action. In my action I check the value of input button.
我之前这样做的方式是将我的表单发布到相同的操作中。在我的操作中，我检查输入按钮的值。
So In your case you should do following on your View. Keep the name of both input submit same but different value.
因此，在您的情况下，您应该在您的视图上执行以下操作。保持两个输入的名称提交相同但不同的值。
<% using (Html.BeginForm("SignUp", "SetUp", FormMethod.Post))
{%>
<%: Html.ValidationSummary()%>
<input type="submit" value="Register" name="actionName" />
<input type="submit" value="Cancel" name="actionName" class="cancel">Cancel</input>
}
And on your controller
在你的控制器上
public ActionResult SignUp_Register(SignUpViewModel vm,string actionName)
{
if(actionName =="Register")
//Do something;
if(actionName =="Cancel")
//Do something;
return View();
}
In standard cases these should work....
在标准情况下，这些应该工作......
Let me highlight something interesting now...!!
现在让我强调一些有趣的事情......！
1)On Submit event of the form if you are disabling all input type of submit in your JavaScript to disable double submit, then you will always get null values for them in the controller as they are disabled.
1）在表单的提交事件上，如果您在 JavaScript 中禁用所有输入类型的提交以禁用双重提交，那么当它们被禁用时，您将始终在控制器中获得它们的空值。
2)I realized that you have cancel class on your submit which has some unintended behavior if you are using jQuery validation. Ref: http://docs.jquery.com/Plugins/Validation/Reference
2）我意识到您在提交时取消了类，如果您使用 jQuery 验证，这会出现一些意外行为。参考：http: //docs.jquery.com/Plugins/Validation/Reference
Hope this helps..!!
希望这可以帮助..！！

You need to set equal the id of the button (View) and the name of the variable to receive (Controller) The value of the button will be sent to the variable
您需要设置等于按钮的 id (View) 和要接收的变量的名称 (Controller) 按钮的值将被发送到变量
<button type="submit" id="btnRegister" name="btn" class="btn btn-primary" value="Register">
Register
</button>
<button type="submit" id="btnCancel" name="btn" class="btn btn-primary" value="Cancel">
Cancel
</button>
And your controller:
还有你的控制器：
[HttpPost]
public ActionResult SignUp_Register(string btn, SignUpViewModel vm m)
variable btn will be either "Register" or "Save" depending on the button clicked
变量 btn 将是“注册”或“保存”，具体取决于单击的按钮
