MVC Bootstrap形成样式问题

Question

我的bootstrap mvc表单存在一个小问题。当我添加我的剃刀时，表单组的边距似乎不起作用。任何帮助将不胜感激。

这是不能正确使用样式的表单

 @using (Html.BeginForm("Contact", "Home"))
{
@Html.AntiForgeryToken()
@Html.ValidationSummary(true)
<form class="form-horizontal" role="form">
    <div class="form-group">
        <label for="formGroupInputLarge1" class="col-sm-2 control-label">Name</label>
        <div class="col-sm-10">
            @Html.TextBoxFor(m => m.Name, new { @class = "form-control", placeholder = "Fullname", tabindex = 1 })
            @Html.ValidationMessageFor(m => m.Name)
        </div>
    </div>
    <div class="form-group">
        <label for="formGroupInputLarge2" class="col-sm-2 control-label">Email</label>
        <div class="col-sm-10">
            @Html.TextBoxFor(m => m.Email, new { @class = "form-control", placeholder = "Email Address", tabindex = 2 })
            @Html.ValidationMessageFor(m => m.Email)
        </div>
    </div>
    <div class="form-group">
        <label for="formGroupInputLarge3" class="col-sm-2 control-label">Message</label>
        <div class="col-sm-10">
            @Html.TextAreaFor(m => m.Message, new { @class = "form-control", placeholder = "Message", tabindex = 3 })
            @Html.ValidationMessageFor(m => m.Message)
        </div>
    </div>
    <div class="form-group">
        <div class="col-sm-offset-2 col-sm-10">
            <button type="submit" class="btn btn-primary btn-lg">Send Mail</button>
        </div>
    </div>
</form>
}

但是一旦我删除了Begin表单，它就会采用正确的样式

<form class="form-horizontal" role="form">
    <div class="form-group">
        <label for="formGroupInputLarge1" class="col-sm-2 control-label">Name</label>
        <div class="col-sm-10">
            @Html.TextBoxFor(m => m.Name, new { @class = "form-control", placeholder = "Fullname", tabindex = 1 })
            @Html.ValidationMessageFor(m => m.Name)
        </div>
    </div>
    <div class="form-group">
        <label for="formGroupInputLarge2" class="col-sm-2 control-label">Email</label>
        <div class="col-sm-10">
            @Html.TextBoxFor(m => m.Email, new { @class = "form-control", placeholder = "Email Address", tabindex = 2 })
            @Html.ValidationMessageFor(m => m.Email)
        </div>
    </div>
    <div class="form-group">
        <label for="formGroupInputLarge3" class="col-sm-2 control-label">Message</label>
        <div class="col-sm-10">
            @Html.TextAreaFor(m => m.Message, new { @class = "form-control", placeholder = "Message", tabindex = 3 })
            @Html.ValidationMessageFor(m => m.Message)
        </div>
    </div>
    <div class="form-group">
        <div class="col-sm-offset-2 col-sm-10">
            <button type="submit" class="btn btn-primary btn-lg">Send Mail</button>
        </div>
    </div>
</form>

Answer 1

您创建的嵌套表单（表单中的表单）无效且不受支持。变化

@using (Html.BeginForm("Contact", "Home"))

到

@using (Html.BeginForm("Contact", "Home", FormMethod.Post, new { @class="form-horizontal", role="form" }))

并删除第二个表单元素（及其结束标记）

<form class="form-horizontal" role="form">

作为旁注，<label for="formGroupInputLarge1" ...>未创建正确的label元素，因为for属性与表单中的任何元素没有任何关系。而是使用@Html.LabelFor(m => m.Name, new { @class = "col-sm-2 control-label" })将标签与文本框相关联。

Answer 2

删除第二个表单并使用：

@using (Html.BeginForm("ActionName", "ControllerName", 
            null, 
            FormMethod.Post, new { @class="form-horizontal" }))
{

<div class="col-md-8">
        <section id="loginForm">
            @using (Html.BeginForm("Login", "Account", new { ReturnUrl = ViewBag.ReturnUrl }, FormMethod.Post, new { @class = "form-horizontal", role = "form" }))
            {
                @Html.AntiForgeryToken()
                <h4>Use a local account to log in.</h4>
                <hr />
                @Html.ValidationSummary(true, null, new { @class = "text-danger" })
                <div class="form-group">
                    @Html.LabelFor(m => m.Email, new { @class = "col-md-2 control-label" })
                    <div class="col-md-10">
                        @Html.TextBoxFor(m => m.Email, new { @class = "form-control" })
