近来因为要搞一些swt游览器提交表单的功能,用到了Browser控件,发现Browser控件可以用Js来提交表单,但是我做了个例子,访问了淘宝的一个登录页面https://login.taobao.com/member/login.jhtml,但是提交表单Post请求时,没有反应,不知道是哪里的问题,下面给出代码,请高手指点下,谢谢!!package com.browser;import java.net.HttpURLConnection;

第一步:登录淘宝
第二步:访问代付款链接
第三步:完成代付款
第四步:关闭浏览器
我想完成上面4步,现在我只写了前两步,当我再加上第三步的时候,就会出现先执行第三步,再执行第二步的情况,因为第二步比较慢,要检测支付宝,看下有什么办法可以按第一步,第二步,第三步,第四步这样执行下来,现在是步骤乱了。我将代码放出来,可以直接在IDE运行的,大家帮忙看下package com.browser;import java.io.File;
