Question

我正在开发MVC 3应用程序并使用razor语法。

在这个应用程序中，我正在发表评论工具。

我在每个Div中添加了评论链接。。当用户单击该注释链接时，它会加载包含添加注释的控件组的局部视图。

现在我的问题是关于删除新评论。

我有删除已保存评论的代码..它工作正常......

现在问题是当用户输入新评论并尝试删除它时不会被删除...

见蓝色方块。

您可以通过此图片了解...

enter image description here

我的代码是......

<script src="../../Scripts/jquery.validate.min.js" type="text/javascript"></script>

@model  IEnumerable<CRMEntities.Comment>

<html xmlns="http://www.w3.org/1999/xhtml">

在附加新div的成功方法中，只需将类添加到CSS为display:none的删除按钮

例如：

$("p.p12").append('<div style="background-color:#FAFAFA;">Recently Added... <br /><a href="@Url.Action("Details", "Employee", new { id = "__id__" })'.replace('__id__', data.OwnerID) + '">' + data.OwnerName + '</a>'+ data.cmtDateTime +'<button type="button" id=' + data.Id  + ' class="deleteComment hidden">Delete</button></span><br />' + data.msg + '</div>')

CSS：

.hidden { display: none;}

当您准备好显示它时，您只需从按钮中删除该类。
