Input type checkbox with MVC razor
提问by JoshYates1980
Why is the value of my checkbox not passed to my ViewModel?
为什么我的复选框的值没有传递给我的 ViewModel？
My View (I omitted input tags not relevant for this post):
我的观点（我省略了与这篇文章无关的输入标签）：
@model Pro.WebUI.ViewModels.UserViewModel
@using (Html.BeginForm("ManageUsers", "Administration", FormMethod.Post,
new { id = "request-form", @class = "form-horizontal" }))
{
<div class="form-group">
<label for="inputAuthorize" class="col-lg-2 control-label">Authorize</label>
<div class="col-lg-8">
<input type="checkbox" id="Authorized" name="Authorized" value="@Model.Authorized" />
</div>
</div>
<div class="form-group">
<div class="col-lg-10 col-lg-offset-2">
<br /><br />
<button type="submit" class="btn btn-primary">Submit Request</button>
</div>
</div>
}
My ViewModel:
我的视图模型：
public class UserViewModel
{
[Key]
public string UserID { get; private set; }
public string UserName { get; set; }
public string FirstName { get; set; }
public string LastName { get; set; }
public bool Authorized { get; set; }
public string Email { get; set; }
public string Phone { get; set; }
public string Notes { get; set; }
}
My Controller:
我的控制器：
[HttpPost]
public ActionResult ManageUsers(UserViewModel model)
{
if (ModelState.IsValid)
{
ProcurementUser obj = new ProcurementUser();
obj.UserName = model.Email;
obj.FirstName = model.FirstName;
obj.LastName = model.LastName;
obj.Email = model.Email;
obj.Phone = model.Phone;
obj.Authorized = model.Authorized;
UserRepository.SaveUser(obj);
//success message
}
return View(model);
}
I did not include all input tags but when I step through the code without the checkbox, all values are passed. I looked at other checkbox questions on SOF but they mostly use the @Html.Checkbox or @Html.CheckboxFor. I would like to just use input type="checkbox"
我没有包含所有输入标签，但是当我在没有复选框的情况下单步执行代码时，所有值都会被传递。我查看了 SOF 上的其他复选框问题，但它们大多使用 @Html.Checkbox 或 @Html.CheckboxFor。我只想使用 input type="checkbox"
回答by Dush
If we need to use <input>filed instead of @Html.CheckboxFor, we can use "checked=\"checked\""syntax as in this code:
如果我们需要使用<input>归档而不是@Html.CheckboxFor，我们可以使用"checked=\"checked\""如下代码中的语法：
<input type="checkbox" id="Authorized" name="Authorized" value="true" @(Model.Authorized ? "checked=\"checked\"" : "") />
回答by Zhaph - Ben Duguid
As has been hinted at in the comments the issue you're having is that you're not really creating your checkbox correctly:
正如评论中所暗示的，您遇到的问题是您没有真正正确地创建复选框：
Assuming your model has Authorized = trueyour mark-up would be:
假设您的模型有Authorized = true您的标记将是：
<input type="checkbox" id="Authorized" name="Authorized" value="true" />
Similarly the falsestate would result in:
同样，false状态将导致：
<input type="checkbox" id="Authorized" name="Authorized" value="false" />
But these aren't "checked" checkboxes - they're still "unchecked", and need the checkedattribute setting:
但这些不是“选中”复选框 - 它们仍然“未选中”，并且需要checked属性设置：
<input type="checkbox" id="Authorized" name="Authorized" value="true" checked />
As Stephen points out - an unchecked checkbox will not send any data back to the server so that you don't get confused about which options where selected.
正如斯蒂芬指出的那样 - 未选中的复选框不会将任何数据发送回服务器，因此您不会对选择了哪些选项感到困惑。
Finally, as has also been noted, your <label>element is for an non-existent field looking for inputAuthorizeinstead of Authorized.
最后，正如也已经指出的，您的<label>元素是针对不存在的字段寻找inputAuthorize而不是Authorized.
All of these issues would be taken care of for you if you were to use the @Html.CheckboxForand @Html.LabelForhelper classes.
如果您要使用@Html.CheckboxFor和@Html.LabelFor帮助类，所有这些问题都会为您解决。
