script 里 function 如何调用字段 [复制链接]

<script type="text/javascript">
function set_application()
{
document.forms["application"].mailto.value="service@xxa.com";
document.forms["application"].mailreply.value="bluexq@vip.qq.com";
document.forms["application"].mailsubject.value="";
document.forms["application"].mailbody.value="";
                                  

return Check_ZdyForm("application");
}

function application_zdycheck(){
return true;
}
</script></div>


邮件主题需要调用一个字段，调用了无效。
