使用部分视图在MVC 5中移动表单外部的提交按钮

Question

在MVC 5中,

我有一个用于编辑的对话框.

"内容"区域是从"部分"视图创建的.

如果我在Partial视图中的表单中有提交按钮,则它可以正常工作.但我希望保存按钮位于对话框的按钮上,因此在窗体和部分视图之外.

现在的问题是表单数据没有发布.你会如何解决这个问题？

我有两个想法:1)将表单包装在Partial视图之外2)发出一个AJAX请求而不使用帮助程序,并以某种方式从表单中收集数据？感觉不是正确的方式.

对话:

<div id="myModal" class="modal" tabindex="-1" role="dialog" aria-labelledby="myModalLabel" aria-hidden="true">
    <div class="modal-dialog">
        <div class="modal-content">
            <div class="modal-header">
                <button type="button" class="close" data-dismiss="modal" aria-label="Close"><span aria-hidden="true">&times;</span></button>
                <h4 class="modal-title" id="myModalLabel">Edit database connection</h4>
            </div>
            <div class="modal-body">
                @{ Html.RenderPartial("View");  }
            </div>
            <div class="modal-footer">
                <button id="saveBtnSettings" type="button" class="btn btn-primary">Save</button>
                <button type="button" class="btn btn-default" data-dismiss="modal">Close</button>
            </div>
        </div>
    </div>
</div>

对话框javascript

var saveSettings = function () {
    var url = buildUrl("Edit", "Setting");

    $.ajax({
        type: "POST",
        url: url
    })
    .done(function (data, textStatus, jqXhr) {
        alert('done' + data);
    })
    .fail(function (jqXhr, textStatus, errorThrown) {
        alert(textStatus.toUpperCase() + ": " + errorThrown + 'Could not load html. ');
    });
};

局部视图

@using (Ajax.BeginForm("Edit", "Setting", new AjaxOptions { UpdateTargetId = "div" }))
{
    <fieldset>
        @Html.AntiForgeryToken()

        <div class="form-horizontal">
            @Html.ValidationSummary(true, "", new { @class = "text-danger" })
            <div class="form-group">
                @Html.LabelFor(model => model.User, htmlAttributes: new { @class = "control-label col-md-2" })
                <div class="col-md-10">
                    @Html.EditorFor(model => model.User, new { htmlAttributes = new { @class = "form-control" } })
                    @Html.ValidationMessageFor(model => model.User, "", new { @class = "text-danger" })
                </div>
            </div>

            <div class="form-group">
                @Html.LabelFor(model => model.DataSource, htmlAttributes: new { @class = "control-label col-md-2" })
                <div class="col-md-10">
                    @Html.EditorFor(model => model.DataSource, new { htmlAttributes = new { @class = "form-control" } })
                    @Html.ValidationMessageFor(model => model.DataSource, "", new { @class = "text-danger" })
                </div>
            </div>

        </div>
    </fieldset>
}

部分视图 - 使用表单内的按钮

@using (Ajax.BeginForm("Edit", "Setting", new AjaxOptions { UpdateTargetId = "div" }))
{
    <fieldset>
        @Html.AntiForgeryToken()

        <div class="form-horizontal">
            @Html.ValidationSummary(true, "", new { @class = "text-danger" })
            <div class="form-group">
                @Html.LabelFor(model => model.User, htmlAttributes: new { @class = "control-label col-md-2" })
                <div class="col-md-10">
                    @Html.EditorFor(model => model.User, new { htmlAttributes = new { @class = "form-control" } })
                    @Html.ValidationMessageFor(model => model.User, "", new { @class = "text-danger" })
                </div>
            </div>

            <div class="form-group">
                @Html.LabelFor(model => model.DataSource, htmlAttributes: new { @class = "control-label col-md-2" })
                <div class="col-md-10">
                    @Html.EditorFor(model => model.DataSource, new { htmlAttributes = new { @class = "form-control" } })
                    @Html.ValidationMessageFor(model => model.DataSource, "", new { @class = "text-danger" })
                </div>
            </div>
            <p>
                <input type="submit" value="Calculate" /> @* WORKS WITH BUTTON INSIDE OF FORM *@
            </p>
        </div>
    </fieldset>
}

Answer 1

您可以通过指定form属性在表单标记之外放置一个提交按钮(仅限HTML5)

<form .... id="editform">
  ....
</form>

<input type="submit" form="editform" />

请注意,如果提交按钮具有值属性,则不会回发它.

另一个选择可能是使用CSS来定位它.
