我正在 MVC4 中创建一个新视图并遇到了这个问题。为了测试它，我用除了主布局和一个按钮之外的东西制作了一个视图。每当我单击此按钮时，事件处理程序都不会触发。如果我通过 $("#btnSearch").click() 在 Firebug 中手动调用点击，它就可以工作。我有许多其他页面使用相同的主布局编写，没有问题。我不知道是什么原因造成的，它存在于 FF 和 IE 中（我的工作中没有 Chrome）并且没有抛出 JS 错误。我觉得我在这里要疯了，我真的很感谢任何人来看看。
这是视图：
@{
ViewBag.Title = "sp";
}
<input type="button" id="btnSearch" class="btn btn-info" value="Search">
@section scripts {
<script type="text/javascript">
$(document).ready(function () {
alert($("#btnSearch").length);
$("#btnSearch").click(function () {
alert("Click");
});
});
</script>
}
整个渲染页面（对不起！）

<li>Searches are limited to 1000 records</li>
<li>Use quotes to put words together, ex) "Dom Perignon"</li>
<li>Use a dash ("-") to search for part of a word, ex) "Dom Peri-"</li>
