我的项目在 MVC 4 中。当重新加载页面时，我的脚本在 _Layout.cshtml 中，出现以下错误：JScript 运行时错误：'$' 未定义

My Partial View:
我的部分观点：
<script type="text/javascript">
$('#lnkOrganizar').click(function () {
if (($('.frozenTopC').css('display') != 'none') && ($('.frozenTopConteudo').css('display') != 'none')) {
$('.frozenTopC').css('display', 'none');
$('.frozenTopConteudo').css('display', 'none');
}
else {
$('.frozenTopC').css('display', 'table-cell');
$('.frozenTopConteudo').css('display', 'table-cell')
}
});
</script>

jquery isn't present.
jquery 不存在。
Look at this line: <script type="text/javascript" src="~/Scripts/jquery.qtip-1.0.0-rc3.min.js"> </script>
看看这一行： <script type="text/javascript" src="~/Scripts/jquery.qtip-1.0.0-rc3.min.js"> </script>
Check that you have that Scripts/jquery.qtip-1.0.0-rc3.min.json the server
检查您Scripts/jquery.qtip-1.0.0-rc3.min.js在服务器上是否有
It is also NOT usual to refer to your home directory there - where you have the "~". If your script is in a Scriptsdirectory then you just use Scripts/jquery.qtip-1.0.0-rc3.min.jsbecause with a web server, everything is within it's root (top level) directory.
在那里引用您的主目录也是不常见的 - 在那里您有“ ~”。如果您的脚本在一个Scripts目录中，那么您只需使用，Scripts/jquery.qtip-1.0.0-rc3.min.js因为对于 Web 服务器，所有内容都在它的根（顶级）目录中。
Also is this file the main jquery library? It's not clear to me whether this is just your script code and if so you'll need to include the main js library with something like:
这个文件也是主要的jquery库吗？我不清楚这是否只是您的脚本代码，如果是，您需要包含主 js 库，例如：
<script src="//ajax.googleapis.com/ajax/libs/jquery/1.10.2/jquery.min.js"></script>
btw, aim to use lowercase for directory names - scriptsnot Scriptsas it will make your life easier in the long run. I would also recommend scriptnot scriptsas many directories have multiple files (their purpose after all) so most folks use singular directory. This is closer to a preference though than the ~issue.
顺便说一句，旨在用小写的目录名称-scripts不是Scripts因为它会让你的生活，从长远来看更容易。我还建议script不要scripts有多个目录有多个文件（毕竟它们的目的），所以大多数人使用单个目录。尽管这比~问题更接近于偏好。
Also, while debugging and playing around, remember that you can actually have the script in the same file, within <script>tags, not in a separate file. Not recommended long-term as a good practice but useful for seeing where the issue is.
此外，在调试和播放时，请记住，您实际上可以将脚本放在同一个文件中，在<script>标签内，而不是在单独的文件中。不推荐长期作为一种好的做法，但有助于查看问题所在。
