今天写测试的文件，在html中引用jquery库的时候，被自己犯下的错误蠢哭了
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<title>上传图片</title>
<script type="text/javascript" src="./js/jquery-1.11.3.min.js"></script>
</head>
<body>
<form method="post" enctype='multipart/form-data'>
<input type="file" id="mypic" name="mypic" οnchange="upload()" accept="image/*">
<input type="submit" id="tanchu">
</form>
<script type="text/html">
$(function(){
function upload()
{
alert(111);
}
})
</script>
</body>
</html>最后发现是script类型写错了，应该是type="text/javascript";
<script type="text/javascript">
$(function(){
function upload()
{
alert(111);
}
})
</script>
