我有一个表单，其中包含一些简单的 javascript 来验证一个简单的问卷。它在表单中的输入上使用了 name 属性，但现在该页面已与客户端 CMS 集成，它需要使用我无法使用的特定命名约定。
旧表单的输入如下：
<input type="text" name="firstName" />
但是对于 cms，所有字段都需要"fields[firstName]"，例如：
<input name="fields[first-name]">
我怎样才能让它工作。
现有的JS如下：
function validate_form ( )
{
valid = true;
if ( ( document.register.question[0].checked == false ) && ( document.register.question[1].checked == false ) && ( document.register.question[2].checked == false ) )
{
alert ( "Please choose an answer" );
valid = false;
}
else if ( document.register.form_title.value == "" )
{
alert ( "Please fill in the 'Title' box." );
valid = false;
}
else if ( document.register.fName.value == "" )
{
alert ( "Please add your First Name" );
valid = false;
}
else if ( document.register.lName.value == "" )
{
alert ( "Please add your Last Name" );
valid = false;
}
else if ( document.register.email.value == "" )
{
alert ( "Please add a valid email address" );
valid = false;
}
else if ( document.register.country.selectedIndex == 0 )
{
alert ( "Please select your Country" );
valid = false;
}
else if ( document.register.dob1.selectedIndex == 0 )
{
alert ( "Please ensure your date of birth is complete" );
valid = false;
}
else if ( document.register.dob2.selectedIndex == 0 )
{
alert ( "Please ensure your date of birth is complete" );
valid = false;
}
else if ( document.register.dob3.selectedIndex == 0 )
{
alert ( "Please ensure your date of birth is complete" );
valid = false;
}
else if ( document.register.terms.checked == false )
{
alert ( "Please check the Terms & Conditions box." );
valid = false;
}
return valid;
}
