我有一个模型Vehicle
,我的模型有一个Options
列表。
在我的“创建”视图中,如何添加要传递给控制器的多个选项? 期权金额可以从0变化到10 + ..
我的想法是在其旁边放置一个带有按钮的文本字段,当单击该按钮时,文本字段的值将传递给带有Javascript的标签。
但我不知道如何将我的标签值传递给我的控制器。
我的观点:
@using (Html.BeginForm("Edit", "VehicleModels", null, FormMethod.Post, new { enctype = "multipart/form-data" }))
{
@Html.AntiForgeryToken()
<div class="form-horizontal">
<h4>VehicleModels</h4>
<hr />
@Html.ValidationSummary(true, "", new { @class = "text-danger" })
@Html.HiddenFor(model => model.Id)
<div>
@Html.LabelFor(model => model.Options)
<ul>
@foreach (var optie in Model.Options)
{
<li>@optie.Naam @Html.ActionLink("X", "DeleteOption", new { opId = optie.OptieId, vehId = optie.VehicleModelsID })</li>
}
</ul>
<input type="text" id="optienaam" /> <input type="button" value="Toevoegen" class="btn btn-default" onclick="optiestoevoegen()" />
<br />
<label id="optielabel"></label>
</div>
<div class="form-group">
<div class="col-md-offset-2 col-md-10">
<input type="submit" value="Save" class="btn btn-default" />
</div>
</div>
</div>
}
<div>
@Html.ActionLink("Back to List", "Index")
</div>
使用Javascript:
function optiestoevoegen() {
var elm;
elm = document.createElement("p");
elm.innerHTML = document.getElementById('optienaam').value;
document.getElementById('optielabel').appendChild(elm);
}
这会生成一个很好的列表,列出所有正在添加的选项,但实际上并不是将它们传递给控制器的直接方式。

在视图中为标签添加隐藏输入
<label id="optielabel"></label>
<input type="hidden" id="optielabelVal" name="optielabel" />
当你的用户按下按钮时,你的javascript会将新标签附加到该隐藏输入的现有值。
function optiestoevoegen() {
var elm;
elm = document.createElement("p");
elm.innerHTML = document.getElementById('optienaam').value;
document.getElementById('optielabel').appendChild(elm);
// for hidden input
var optieVal = document.getElementById('optielabelVal').value;
optieVal = optieVal + ';' + document.getElementById('optienaam').value;
document.getElementById('optielabelVal').value = optieVal;
}
