如何解决视图中的Asp.net部分视图无法从视图中识别
我创建了一个小博客,并且有一个视图,并在其中嵌入了部分视图。 嵌入的局部视图是“赞”按钮(链接)。
它出现在视图中,但是当我单击“赞”锚点时,它不会进入部分视图。 我有一个警报和控制台日志,它们没有出现。
当我单击它时,#将附加到URL。
我在做什么错? 另外,我想从父视图中的按钮引用值。 我尝试:var blogId = $(this).attr(“ data-id”);
对吗?
---视图-父级。

解决方法
在局部视图中,我必须删除:
@section Scripts
{
}
环绕JavaScript
只有:
@Scripts.Render("~/bundles/jquery").
没有它,我得到:未捕获的ReferenceError:未定义$。 没有引入图书馆。
建议,而不是:
$(document).ready(function ()
和
@Scripts.Render("~/bundles/jquery")
我可以使用:
document.addEventListener("DOMContentLoaded",function ()
没有
@Scripts.Render("~/bundles/jquery")
所以现在正在执行脚本部分。
现在,要将值从父视图传递到局部视图,我必须在父视图中创建一个模型:
@{
double parentBlogId = @Model.BlogPublishedByBlogId.BlogId;
}
并将其作为:
<div class="row">
<div>
@Html.Partial("_BlogLikeOrDislike",parentBlogId)
</div>
</div>
并通过部分视图的点击功能接收它:
var parentBlogId = @Model;
