上面是我的Jsp代码,其它的部分都能正常显示并能正确运行,只有我加粗的那部分javascript脚本怎么也弹不出来,不知为什么
------解决方案--------------------看看编译后的jsp页面有么有你加粗的那些代码,可以给浏览器中的代码贴上来看看
------解决方案--------------------IE安全限制?
------解决方案--------------------是alert not alter
hehe
------解决方案--------------------alert();
------解决方案--------------------alert( '请输入用户名、密码 ');
