有下面一段代码：判断email和username是否为空的，我想让email的值=username的值，该怎么改呢？就是不让人填email的文本框，自动取他填的username的值！
function submitPwdInfo()
{
var frm = document.forms['getPassword'];
var user_name = frm.elements['user_name'].value;
var email = frm.elements['email'].value;
var errorMsg = '';
if (user_name.length == 0)
{
errorMsg += user_name_empty + '\n';
}
if (email.length == 0)
{
errorMsg += email_address_empty + '\n';
}
else
{
if ( ! (Utils.isEmail(email)))
{
errorMsg += email_address_error + '\n';
}
}
if (errorMsg.length > 0)
{
alert(errorMsg);
return false;
}
return true;
}
下面是表单代码！
复制内容到剪贴板
代码:
<form action="user.php" method="post" name="getPassword" onsubmit="return submitPwdInfo();">
<table width="100%" border="0" align="center" cellspacing="8">
<tr>
<td colspan="2" align="center"><strong>{$lang.username_and_email}</strong></td>
</tr>
<tr>
<td width="39%" align="right">{$lang.username}:</td>
<td width="61%"><input name="user_name" id="getusername" type="text" size="30" /></td>
</tr>
<tr>
<td align="right">{$lang.email}:</td>
<td><input name="email" type="text" size="30" id="getemail"/></td>
</tr>
<tr>
<td colspan="2" align="center"><input type="hidden" name="act" value="send_pwd_email" />
<input type="submit" name="submit" value="{$lang.confirm_submit}" />
<input name="button" type="button" onclick="history.back()" value="{$lang.back_page_up}" /> </td>
</tr>
</table>
</form>[
