javascript语句执行的怪有关问题

javascript语句执行的怪问题？
最近做一个在XML里使用javascript调用远程Web Services的程序，可是我遇到了一个怪问题:
<?xml version="1.0" encoding="UTF-8"?>

以上那个onsubmit函数的第二行(alert('确定吗？');)注释掉的话，就无法插入数据库，按照上面的代码可以插入数据库可是我并不要一个警告框(alert('确定吗？');)，从原理和html代码中的实践没有alert('确定吗？');都可以插入数据库。而且我把alert('确定吗？');改为return false;就可以插入数据库不过后面的代码就取消执行。应该没有return false;,调用的函数可以一直执行下去的啊。你们说这怪不怪？有没有这方面的高手指点一下。

看看这个属性

1.alert()后才能执行...
原因可能是window_onload(3)里的回调函数还没有执行完毕，比如webservice的结果还没有返回。解决办法是加个标志，如果还没返回结果，延迟调用本函数（setTimeout，或看看我的博客中关于doLater的用法）;
2、获得URL，可以看看document.location对象。它有：host,hostname,href,pathname,port,protocol等属性，应该可以满足你的需要。
