廢話不多說,直接上例子:
html代碼:
<div class="layui-form-item" >
<label for="" class="layui-form-label">選擇文件</label>
<div class="layui-input-block" id="file">
</div>
</div>
引入css樣式文件:
<link rel ="slylesheet" type="text/css" href="/backwebuploader/webuploader0.1.5/webuploader.css">
引入js文件:
<script src="/backwebuploader/webuploader0.1.5/webuploader.js" charset="utf-8"></script>
jQuery代碼:
var $list = $("#file");
// webupload 上傳
var uploader = WebUploader.create({
// pick: "#file", // 選擇文件的按鈕。可選
pick: { id: '#file', multiple: false, innerHTML: '選擇文件' },
swf: '__PUBLIC__/backwebuploader/webuploader0.1.5/uploader.swf', // swf文件路徑
server: "url", // 文件接收服務端url。
auto: true,
threads: 1,//併發數
chunked: true, //是否要分片處理大文件上傳
chunkSize: 2 * 1024 * 1024, //分片上傳,每片2M

fileSingleSizeLimit: 2 * 1024 * 1024 * 1024, // 單個文件大小限制
formData: {
// 自定義參數
// guid: WebUploader.Base.guid()
},
accept: {
title: 'Video',
extensions: 'mp4,avi,rm,iso,wmv,mkv', // 文件類型
mimeTypes: 'video/*'
},
duplicate: true,
});
// 當有文件被添加進隊列的時候

'</div>' );
});
uploader.on('error', function (error) {
if (error == 'Q_EXCEED_SIZE_LIMIT') {
