情况:在我的C#/ MVC 4解决方案中,我正在使用一个带有局部视图的视图。视图是一个带有提交按钮的表单。部分视图使用隐藏的div,但如果选中该复选框,则可以显示。
问题:如果隐藏了部分视图,则提交正常。如果未隐藏部分视图,则提交会导致页面无响应,如果等待3分钟左右,则提交最终会按预期工作。
代码如下。提前感谢您的考虑。我是一名新手开发者,因此欢迎所有评论,建议和批评。
代码:
模型
namespace MyModels
{
public class MainModel
{
public SelectListItem Things { get; set;}
public IEnumerable<OtherModel> MoreThings { get; set;}
}
}
查看 //名为MyView @model MyModels.MainModel @using MyModels @if(Model!= null){
using (Html.BeginForm("MyViewName", "MyControllerName", FormMethod.Post, new { id = "view-form" }))
{
@Html.LabelFor(model => model.things)
@Html.DropDownList("", (Selectist)ViewBag.things)
@Html.ValidationMessageFor(model => model.field1)
@Html.CheckBoxWithLabel("aNameAttribute", Model.valueAttribute.ToString(), "anIdAttribute", Model.valueAtttribue ==1, "aLabel", "a_Toggle_Class")
<div class="treeview" style="display: none;">
<fieldset>
<legend>Title</legend>
//view causing issues replaces the div below
<div id="replacedDiv"></div>
</fieldset>
</div>
<p>
<input type="submit" value="Submit" />
</p>
}
}
<script type="text/javascript">
$(document).ready(function () {
$.ajax({
url: "/MyController/MyPartialView",
contentType: "application/html; charset=utf-8",
cache: "false",
type: "GET",
datatype: "html"
})
.success(function (result) {
$('#replacedDiv").html(result);
})
});
</script>
部分视图
//named _MyPartialView
@model MyModels.MainModel
@using MyModels
@foreach (var moreThings in ViewBag.moreThings)
{
<div id="replacedDiv">
<label>
<input type="checkbox" id=@moreThings.id value=@moreThings.name />@moreThings.name </label>
</div>
}
控制器
namespace Main.Controllers
{
public class MyController
{
[HttpGet]
public ActionResult Index(MainModel model)
{
return View(model);
}
public ActionResult MyView()
{
var model = new MainModel();
return View(model);
}
public ActionResult MyPartialView(MainModel model)
{
<OtherModel> moreThings = BLotherModel.GetMoreThings();
ViewBag.moreThings = moreThings;
return PartialView("_MyPartialView", promotion);
}
[HttpPost]
public ActionResult MyView(FormCollection collection)
{
MainModel model = new MainModel();
return SaveModel(model);
}
}
}
答案 0 :(得分:2)
在你正在使用的ajax中:
$('#replacedDiv").html(result);
但您的部分视图包含在循环中生成的<div id="replacedDiv">
用以下内容替换部分视图代码:
@foreach (var moreThings in ViewBag.moreThings)
{
<label>@moreThings.name </label>
<input type="checkbox" id=@moreThings.id value=@moreThings.name />
}
它应该没问题
