Ext.ux.UploadDialog的使用

最近使用了Ext.ux.UploadDialog，现在总结一下：
1、导入Ext.ux.UploadDialog包

<link rel="stylesheet" type="text/css" href="<c:url value="/widgets/UploadDialog/css/Ext.ux.UploadDialog.css"/>">
		<script type="text/javascript" src="<c:url value="/widgets/UploadDialog/Ext.ux.UploadDialog.js"/>"></script>
		<script type="text/javascript" src="<c:url value="/widgets/UploadDialog/Ext.ux.UploadDialog.packed.js"/>"></script>
		
		<script type="text/javascript" src="<c:url value="/widgets/UploadDialog/locale/zh_CN.utf-8.js"/>"></script>

注意包中没有包含zh_CN.utf-8.js，自己可以进行中文化的
2、产生上传文件的对话框代码

function uploadSw(){ 
  var dialog = new Ext.ux.UploadDialog.Dialog({
  	url: 'swUpload.shtml?method=uploadFile',
  	reset_on_hide: false,
  	permitted_extensions:['gz'],
  	allow_close_on_upload: true,
  	upload_autostart: false,
  	title:'软件入库'
  });

  //dialog.show('show-button');
  dialog.show();
  dialog.on('uploadsuccess', onUploadSuccess);
}

function onUploadSuccess(dialog, filename, resp_data, record){
  // 回调函数代码
}

注意：提交时，默认提交的文件名是file 可以修改 post_var_name: 'fileName'修改
