所以我有以下字段，基本上是为了创建一个帐户。这只是一个原型。我想知道如何禁用继续按钮，只在所有字段完成后启用按钮。我已经看到这可以使用jQuery和表单来完成，但由于这不是一种形式，它不能正常工作。我知道它可能更容易使用，但我必须使用它们显示的所有字段。所以基本上有一种方法可以使用我已经拥有的东西吗？

您可能没有嵌套表单。
修复后，您可以在输入更改后检查字段是否为空。
$('#continue').click(function(e){
e.preventDefault();
if(checkFields())
$('#form1').find('form').submit();
return false;
});
function checkFields() {
$('#form1 input').each(function(){
if($(this).val() == '')
return false;
else
return true;
});
}
