我对MVC(以及一般而言的Web开发)还很陌生,并且我不断遇到一些“陷阱”,这会导致意外的行为。我正在使用Kendo UI,但是我99%确信我的问题是由于我对Javascript或MVC缺乏了解,而不是与Kendo无关。
您应该可以使用以下代码重现该问题:
型号:
public class DemoClass
{
public int id { get; set; }
public string randomData { get; set; }
public List<DemoPartyDetails> partyDetails { get; set; }
public DemoClass()
{
partyDetails = new List<DemoPartyDetails>();
}
}
public class DemoPartyDetails
{
public int id { get; set; }
public string firstName { get; set; }
public string surname { get; set; }
public string gender { get; set; }
public DemoPartyDetails()
{
}
}
控制器:
public class DemoController : Controller
{
// GET: Demo
public ActionResult Index()
{
DemoClass demo = new DemoClass();
return View(demo);
}
[HttpPost]
public ActionResult Create(DemoClass model)
{
try
{
if (model.partyDetails[0].gender != null)
Console.WriteLine("Party details populated");
else
Console.WriteLine("Something went wrong...");
return RedirectToAction("Index");
}
catch
{
return View();
}
}
}
查看:
@model DemoPortal.Models.DemoClass
<html>
<head>
<meta name="viewport" content="width=device-width" />
<title></title>
</head>
<body>
@using (Html.BeginForm("Create", "Demo", FormMethod.Post))
{
<div>
@Html.EditorFor(model => model.randomData)
</div>
<div>
<a class="k-button k-button-icontext k-add-button" href="#"><span class="k-icon k-i-add"></span>Add Party</a>
@(Html.Kendo().ListView(Model.partyDetails)
.Name("demoListView")
.TagName("div")
.ClientTemplateId("demoTemplate")
.DataSource(dataSource => dataSource
.Model(model => model.Id(x => x.id))
)
.Editable(editable => editable.TemplateName("DemoPartyDetails"))
)
</div>
<input type="submit" value="Submit" />
}
</body>
</html>
<script type="text/x-kendo-tmpl" id="demoTemplate">
<div class="demoParty">
<h3>#:firstName#</h3>
<span>#:surname#</span>
<input type="hidden" name="PartyDetails[#:index(data)#].firstName" value="#:firstName#" />
<input type="hidden" name="PartyDetails[#:index(data)#].surname" value="#:surname#" />
<input type="hidden" name="PartyDetails[#:index(data)#].gender" value="#:gender#" />
</div>
</script>
<script>
$(function() {
var listView = $("#demoListView").data("kendoListView");
$(".k-add-button").click(function(e) {
listView.add();
e.preventDefault();
});
});
function index(dataItem) {
var data = $("#demoListView").data("kendoListView").dataSource.data();
return data.indexOf(dataItem);
}
function maleClick(e) {
document.getElementById("gender").value = "M";
document.getElementById("randomData").value = "random";
var maleButton = document.getElementById("IsMale");
var femaleButton = document.getElementById("IsFemale");
femaleButton.classList.remove("k-primary");
maleButton.classList.add("k-primary");
};
function femaleClick(e) {
document.getElementById("gender").value = "F";
document.getElementById("randomData").value = "random";
var maleButton = document.getElementById("IsMale");
var femaleButton = document.getElementById("IsFemale");
maleButton.classList.remove("k-primary");
femaleButton.classList.add("k-primary");
};
</script>
PartyDetails编辑器模板
@model DemoPortal.Models.DemoPartyDetails
@using (Html.BeginForm())
{
<div>
<div>
<label>Gender:</label>
@(Html.Kendo().Button()
.Name("IsMale")
.Content("Male")
.HtmlAttributes(new { type = "button" })
.Events(ev => ev.Click("maleClick")))
@(Html.Kendo().Button()
.Name("IsFemale")
.Content("Female")
.HtmlAttributes(new { type = "button", @class = "k-primary" })
.Events(ev => ev.Click("femaleClick")))
</div>
@(Html.HiddenFor(model => model.id))
@(Html.EditorFor(model => model.gender))
@(Html.EditorFor(model => model.firstName))
@(Html.EditorFor(model => model.surname))
<div class="btnArea">
<a class="k-button k-update-button" href="\\#"><span class="k-icon k-update"></span></a>
<a class="k-button k-cancel-button" href="\\#"><span class="k-icon k-cancel"></span></a>
</div>
</div>
}
运行此代码时,我可以单击按钮添加一个新的聚会,编辑器模板将按预期显示,然后按“男性”按钮,该按钮将在性别字段中填充“ M”。
然后在确认输入然后按Submit之前,使用通用的“ Test”和“ Person”数据填写其他两个字段。
但是,当我在控制器上放置一个断点时,我发现通过的模型的性别设置为null。但是,姓和名(“测试”和“人”)已完全填充。也按预期填充了randomData。
有趣的是,如果我返回并在“性别”字段中手动键入类似“男性”的内容,那么现在也已填充该字段。仅当我尝试使用javascript设置其值为null时。
最终目的是要在按下按钮时用javascript填充一个隐藏字段,因此如果有人指出我的错误,将不胜感激!
答案 0 :(得分:0)
原来,您需要通过javascript更改值后触发编辑器模板的change事件。
<select name="trip" class="select-trip">
<?php foreach ( $wp_trips as $trip ) {
if ($trip->available && $is_day_trip){
$start = date_i18n("d/m/Y", strtotime($trip->start_date));
$end = date_i18n("d/m/Y", strtotime($trip->end_date));?>
<option value="<?php echo $trip->remote_ID; ?>">
<?php echo $start;
} else {
echo $start . ' T/M ' . $end;
}
} ?>
</select>
