急,帮忙改下程序.

发表于：2007-08-06 16:45:52 楼主

我写的下面无法验证表单填写是否正正确,请高手帮帮忙

这是用javascript在客户端验证表单提交的代码:
<script language= "javascript ">

function checkform（)
{
if（document.form.username.value== " ")
{
alert（ "用户名不能为空! ");
document.form.username.focus（);
}

else if（document.form.passworld.value== " "\\document.form.passworld.value.length <6))
{
alert（ "密码为空或者太短,为保证你的安全请重写 ")
document.form.passworld.focus（);
}

else if（document.form.passworld.value== " "\\（document.form.passworld.value!=（document.form.passworld1.value))
{
alert（ "确认密码为空或者与原密码不一致 ");
document.form.passworld.focus（);
}
}

</script>

这是用户填写的表单程序,下面的onsubmit== "return checkform（); "正确吗?
<form name= "form " method= "post " action= "do-register.jsp " onsubmit= "return checkform（); ">
<label> 用户名
<input name= "username " type= "text " value= " " size= "20 " />
</label>
<p>
<label> 密码
<input name= "userpassworld " type= "password " value= " " size= "20 " />
</label>
</p>
<p>
<label> 确认密码
<input type= "password " name= "userpassworld1 " />
</label>
</p>
<p>
<label>
<input type= "submit " name= "submit " value= "提交 " />
</label>
<label>
<input type= "reset " name= "reset " value= "重置 " />
</label>
</p>
</form>
