jquery ajaxupload实现打开文件夹上传指定位置的文件

参考http://my.oschina.net/u/1398304/blog/338863

自己的代码

// 上传xls文件
	var button = $('#importExcel');
	log(button);
	new AjaxUpload(button, {
		action : 'phoneNoMarket/xlsupload',
		name : 'file',
		onSubmit : function(file, ext) {
			if (!(ext && /^(xls)$/.test(ext))) {
				alert('文件格式不正确,请选择 xls 格式的文件!', '系统提示');
				return false;
			}

			this.disable();
		},
		onComplete : function(file, response) {
			this.enable();
			var k = response.replace("<pre style=\"word-wrap: break-word; white-space: pre-wrap;\">", "").replace("</pre>", "");
			k=eval('('+k+')');
			importlist = k.importData;
			convtohtml2add(k.importData);

			return false;
		}
	});

写在$(function(){});里面

onsubmit提交之前

oncomplete执行完了

$('#importExcel');

是一个超链接，也可以是<div>，button总之是一个对象

java：mybatis+springMVC
