首先需要下载好对应的压缩包，下载地址：https://github.com/kartik-v/bootstrap-fileinput
本人只是简单实用，更多详细的可以再研究一下
<head> <meta charset="UTF-8"/> <link href="./css/bootstrap.min.css" rel="stylesheet"> <script src="./js/jquery-2.0.3.min.js"></script> <script src="./js/bootstrap.min.js" type="text/javascript"></script> <link href="./css/fileinput.css" media="all" rel="stylesheet" type="text/css" /> <script src="./js/fileinput.js" type="text/javascript"></script> <script src="./js/fileinput_locale_zh.js" type="text/javascript"></script> </head>
上三个是必定的因为使用的是bootstrap，下面三个是控件的链接，最好一个是中文的汉化，这就是头部的内容！
<form action="2.php" enctype="multipart/form-data" method="post"> <input id="imgUpload" class="file" name="thumb" type="file" multiple data-min-file-count="1"> <br> <button type="submit" class="btn btn-primary">提交</button> <button type="reset" class="btn btn-default">重置</button> </form>
