为长篇文章道歉,但我想知道在向Sun提交错误报告之前是否可以得到更多建议.

JVM:7u04

操作系统:Windows XP SP3

硬件:奔腾(R)双核E6700 3.20GHz,内存3.25 GB.

浏览:Google Chrome版本19.0.1084.52

当页面加载Applet时,它将一直挂起,直到我关闭它.检查窗口任务管理器,我发现如果杀掉Applet处理器,该页面将不会挂起.我尝试在Applet init()和start()上打印一些消息,但是这些消息没有显示.我只能做的是通过JVM获取完整转储,如下所示.有谁可以告诉我为什么Applet在它开始之前挂起？感谢帮助.

我需要一个在捕获错误时停止执行javascript的函数。例如如下：

function AA()
{
  try{
    executeScript();
  }catch(e){
    //stop execute javascript
  }
}

function executeScript()
{
   throw 'error';
}
function BB()
{
  //some script
}
AA();
BB(); //don't execute when error happening

有人知道怎么做吗？感谢帮助。
