javascript - 使用局部 View 将提交按钮移到 MVC 5 中的表单之外

Question

在 MVC 5 中，

我有一个用于编辑的对话框。

内容区域是从局部 View 创建的。

如果我在部分 View 中的表单内有提交按钮，它就可以工作。但我希望“保存”按钮位于对话框的按钮上，因此位于表单和局部 View 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)将表格包裹在局部 View 之外 2) 发出 AJAX 请求而不使用助手，并以某种方式从表单收集数据？感觉不对。

对话框:

<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 View

@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>
}

局部 View - 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(仅限 HTML5)将提交按钮放置在表单标签之外

<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。

另一种选择可能是使用 css 来定位它。
