首先引入Jquery 引入webuploader插件 及js css
1 <!--引入CSS--> 2 <link rel="stylesheet" type="text/css" href="/webuploader/webuploader.css">
3 <!--引入Jquery--> 4 <script src="https://apps.bdimg.com/libs/jquery/2.1.4/jquery.min.js"></script>
5 <!--引入JS--> 6 <script type="text/javascript" src="/webuploader/webuploader.js"></script>
HTML:
1 <div class="demo"> 2 <div id="uploadfile"> 3 <!--用来存放文件信息--> 4 <div id="the_2655" class="uploader-list"></div> 5 <div class="form-group form-inline"> 6 <div id="picker" style="float:left">选择文件</div> 7 <input type="hidden" value="" id="file" name="file"> 8 <button id="Btn_2655" class="btn btn-default" style="padding: 5px 10px;border-radius: 3px;">开始上传</button> 9 </div> 10 </div> 11 </div>
Script:
1 $(function () { 2 var uploader = WebUploader.create({ 3 // swf文件路径 4 swf: 'webuploader/Uploader.swf', 5 // 文件接收服务端。 6 server: "{:url('index/uploadFile')}", 7 // 选择文件的按钮 8 pick: "#picker", 9 // 不压缩image, 默认如果是jpeg，文件上传前会压缩一把再上传！ 10 resize: false, 11 // 选完文件后，是否自动上传。 12 auto:true, 13 // 图片name 14 fileVal:'file', 15 // 单文件 16 multiple:false, 17 //是否要分片处理大文件上传 18 chunked: true, 19 //分片上传，每片2M，默认是5M 20 chunkSize:5*1024*1024, 21 // 单个文件大小限制 5 G 22 fileSingleSizeLimit: 10*1024* 1024 * 1024, 23 compress : { 24 width: 100, 25 height: 100, 26 compressSize: 0 27 }, 28 }); 29 uploader.on( 'uploadSuccess', function( file,res ) { 30 $('#file').val(res.filePath) 31 }); 32 })
