Javascript未捕获类型错误未定义不是函数
[英]Javascript Uncaught type error undefined is not a function
问题描述
I am trying to include a video file upload feature on my website: 
我正在尝试在我的网站上添加视频文件上传功能：
I am following the example as posted here: http://davidsonsousa.net/en/post/how-to-upload-a-file-using-mvc-3-and-ajax 我正在遵循此处发布的示例： http : //davidsonsousa.net/en/post/how-to-upload-a-file-using-mvc-3-and-ajax
I have included all the necessary libraries in my MVC project.. In my view I included the below header: 我已经在我的MVC项目中包括了所有必需的库。.在我看来，我包括以下标头：
<head>
<title>Videos </title><!-- Bootstrap core CSS -->
<link href="~/Scripts/jquery-lib/jquery.fileupload.css" rel="stylesheet" />
<script src="/Scripts/jquery-lib/jquery-1.9.1.min.js" type="text/javascript"></script>
<script src="/Scripts/jquery-lib/jquery.ui.widget.js" type="text/javascript"></script>
<script src="/Scripts/jquery-lib/bootstrap.min.js" type="text/javascript"></script>
<script src="/Scripts/jquery-lib/jquery.fileupload.js" type="text/javascript"></script>
<script type="text/javascript">
$(document).ready(function () {
$('#fileupload').fileupload({
dataType: 'json',
url: '/Videos/UploadVideoFile/?isrc=' + 'HGTGHTGTYTGT',
autoUpload: true,
done: function (e, data) {
$('.file_name').html(data.result.name);
$('.file_type').html(data.result.type);
$('.file_size').html(data.result.size);
}
}).on('fileuploadprogressall', function (e, data) {
var progress = parseInt(data.loaded / data.total * 100, 10);
$('.progress .progress-bar').css('width', progress + '%');
});
});
</script>
</head>
When I load my web page I get the following errors: 加载网页时，出现以下错误：
Uncaught type error undefined is not a function Which points to this section in the upload script: $('#fileupload').fileupload({ 未捕获的类型错误undefined不是指向上传脚本中此部分的函数：$（'＃fileupload'）。fileupload（{
I also get thee errors: 我也得到你的错误：
Uncaught TypeError: undefined is not a function add:96
Uncaught ReferenceError: jQuery is not defined jquery.ui.widget.js:18
Uncaught ReferenceError: jQuery is not defined bootstrap.min.js:6

It seems like jQuery is not being loaded. 看来jQuery没有被加载。 Open your browser's debugger (F-12) and look at the NETWORK tab. 打开浏览器的调试器（F-12），然后查看“网络”选项卡。 Reload the page and look for a 404 error. 重新加载页面并查找404错误。 You likely have the wrong path. 您可能走错了路。
