<meta http-equiv="Content-Type" content="text/html; charset=UTF-8">

<form name="login" method="post"

<table width="50%">

<tr>

<td align="right">

<font size="+1">

<B>User ID</B>

</font>

</td>

<td>

<font size="+1">

<input type="text" name="user" maxlength="9">

</font>

</td>

</tr>

<tr>

<td align="right">

<font size="+1">

<B>Password</B>

</font>

</td>

<td>

<font size="+1">

<input type="password" name="password"

maxlength="8">

</font>

</td>

</tr>

</table>

<br><br><br>

<font size="+1">

<B>

<input type="button" value="LOGIN" onclick="submitForm()">

     

<input type="button" value="RESET" onclick="resetForm()">

<br>

</B>

</font>

</form>

</center>

</body>

</html>

2.结论:

"formname".submit()作用与<input type="submit" ......>相同,就是提交表单数据,如果button和submit同时存在,只有submit有提交表单的作用
