我找了两个小时了，谁能告诉我怎么找这个aspnetForm?????
function checkform()
{
var f= document.getElementById( "aspnetForm ");
if(trim(f.ctl00_ContentPlaceHolder1_textboxusername.value)== " ")
{
alert ( "请输入用户名 ");
f.ctl00_ContentPlaceHolder1_textboxusername.value= " ";
f.ctl00_ContentPlaceHolder1_textboxusername.focus();
return false;
}
else if(!checkusername(trim(f.ctl00_ContentPlaceHolder1_textboxusername.value)))
{
alert ( "您输入的用户名的格式错误 ");
//f.ctl00_ContentPlaceHolder1_textboxusername.value= " ";
f.ctl00_ContentPlaceHolder1_textboxusername.focus();
return false;
}
if(trim(f.ctl00_ContentPlaceHolder1_TextBoxpassword1.value)== " ")
{
alert ( "密码不能为空!!!!!!!!!!!!! ");
f.ctl00_ContentPlaceHolder1_TextBoxpassword1.focus();
return false;
}
if(f.ctl00_ContentPlaceHolder1_TextBoxpassword1.value!=f.ctl00_ContentPlaceHolder1_TextBoxpassword2.value)
{
alert ( "两次输入密码不一致 ");
f.ctl00_ContentPlaceHolder1_TextBoxpassword1.value= " ";
f.ctl00_ContentPlaceHolder1_TextBoxpassword2.value= " ";
f.ctl00_ContentPlaceHolder1_TextBoxpassword1.focus();
return false;
}
if(trim(f.ctl00_ContentPlaceHolder1_TextBoxemail.value)== " ")
{
alert ( "请输入邮箱地址 ");
f.ctl00_ContentPlaceHolder1_TextBoxemail.value= " ";
f.ctl00_ContentPlaceHolder1_TextBoxemail.focus();
return false;
}
else if(!isemail(trim(f.ctl00_ContentPlaceHolder1_TextBoxemail.value)))
{
alert ( "您输入的邮箱的格式错误 ");
//f.ctl00_ContentPlaceHolder1_textboxusername.value= " ";
f.ctl00_ContentPlaceHolder1_TextBoxemail.focus();
return false;
}
return true;
}
大家看这句：var f= document.getElementById( "aspnetForm ");
这里这个aspnetform我再整个项目中搜了5遍，没找到！！是系统定义的吗？？
我下文有个form1,改了之后还不能用。
f.ctl00_ContentPlaceHolder1_TextBoxemail.focus();
还有这句，这其中的ctl00有是什么东西，也找不到，JS使用的是什么引用方法？？
哪位能给我解释下？？
[解决办法]
不可能吧，这都是页面上的东西，有可能有些东西是程序创建的，在页面上没有，但程序里
面应该有aspnetForm等东西的
[解决办法]
aspnetForm应该是一个form的ID名字如:
<form name= "aspnetForm " id= "aspnetForm ">
...
</form>
ctl00_ContentPlaceHolder1_TextBoxemail是这个form里一个字段的名字如:
<form name= "aspnetForm " id= "aspnetForm ">
<input type= "text " name= "ctl00_ContentPlaceHolder1_TextBoxemail ">
...
</form>
[解决办法]
那他返回的FORM 的ID值是什么?
[解决办法]
顶的都给分吧.嘿嘿
