单击超链接时，文本框不会填充数据库值

Question

当我运行该页面并单击部分表中的值时，onclick 事件没有任何反应。这些值未填充在文本框上。我将锚元素的样式设置为光标：指针。如图所示调试代码，值正确填充，只是没有出现在文本框中。

Answer 1

本身由脚本加载的 Partials 中的脚本将不会执行。您应该将添加点击事件处理程序的代码放置到 #OwnerNav a 元素中索引.cshtml.但是，您需要使用 on 方法并将其应用于页面最初呈现时存在的元素（例如“body”），在事件处理程序名称后传入目标选择器：

$('body').on('click', '#OwnerNav a', function (e) {
    //
