我在简单的jQuery测试中遇到了错误。请参阅图像以显示文件加载的顺序以及在错误发生之前加载jQuery的事实。
这是我的内容页面:
<asp:Content
ID="Content1"
ContentPlaceHolderID="HeadContent"
runat="server">
</asp:Content>
<asp:Content
ID="Content2"
ContentPlaceHolderID="MainContent"
runat="server">
<textarea id="txtArea"> hi </textarea>
<script type="text/javascript">
// Shorthand for $( document ).ready()
$(function () {
$('txtArea').val = "bye";
});
</script>
</asp:Content>
我在主页的末尾,在关闭标签之前加载了我的脚本。
有人知道是什么原因导致了这个简单的错误?
我不认为我的图像在上传。这是显示库已加载的火焰结果。

line"我的脚本在主页的末尾加载,然后在关闭标签之前。"让我认为您的问题是您的问题。
将脚本加载到主页顶部的顶部,这将解决您的问题。
