页面出错，javascript出现问题，向高手求教
页面上有一个一行一列的table（其他按钮，文本框之类的请无视），希望按下时向后台传值，具体看下面代码中的doAction() 这个方法。在执行到submit时提示页面错误（页面左下角出现黄色惊叹号），说对象不支持此属性或方法。document.forms[0].submit();submit本身语法不应该有错误的。现在完全搞不清状况了。求救。

[解决办法]
<input type= "submit " name= "submit " value= "Submit " onclick= "javascript:submitAction( 'submit ') ">
name= "submit " 改成 name= "aaa " 别用submit关键字
