【问题描述】：

我需要建议！我有一个 asp.net mvc razor 页面，我有一个大表格，用于提交银行帐户详细信息和验证银行详细信息所需的其他信息，如地址、最后 4 个 ssn、国家、州等。我想我可以创建一个大的具有 3 个 div（'billingContainer'、'addressContainer'、'accountContainer'）的表单，其中每个 div 包含相关字段，然后在每个容器的底部都有一个“下一步”和“后退”按钮。然后在 javascript/jquery 中检查这些特定字段在每个容器中是否有效。例如，如果地址字段有效，那么我将启用“下一步”按钮以显示/显示“accountContainer”，然后当所有这些字段都被选中并且有效时，我可以提交。所以对用户来说，只有当每个页面上的字段都有效时，才会遍历 2-3 个页面！这是最好的方法，还是我应该为每个不同的容器创建表单，并在每个表单的过程中将数据保存在视图模型中做一个完整的帖子？

问题 - 我如何检查一个容器中所有字段的验证 - 比如“addressContainer”，这样我就可以启用下一个按钮并显示“accountContainer”表单的下一部分？然后，如果用户从一个字段中删除文本并使其无效，我会禁用下一个按钮，这样他/她就不能移动到下一个容器？

这是我的带有剃须刀代码的 html，显示每个部分都有一个围绕它的 div 以及我将显示和隐藏的容器名称

$(".showAddressContainerBtn").off('click').on('click', function() 
  $("#billingContainer").hide();
  $("#addressContainer").show();
  $("#Country1").prop('disabled', true);


  $(".showBillingContainerBtn").off('click').on('click', function() 
    $("#billingContainer").show();
    $("#addressContainer").hide();
  );

  $(".showAccountContainerBtn").off('click').on('click', function() 
    $("#addressContainer").hide();
    $("#accountContainer").show();

    $(".showAddressContainerFromAccountBtn").off('click').on('click', function() 
      $("#addressContainer").show();
      $("#accountContainer").hide();

【参考方案1】：

如何检查一个容器中所有字段的验证——比如“addressContainer”，然后我可以启用下一个按钮并显示“accountContainer”表单的下一部分？

解决方案：我建议您逐步对每个字段执行内联验证，然后如果用户验证所有字段，则允许他执行某些操作或回发到服务器。有关更多信息，请查看该链接 @987654321 @

然后，如果用户从一个字段中删除文本并使其无效，我会禁用下一个按钮，这样他/她就不能移动到下一个容器？

解决方案：您可以再次使用类似的 onTextChange 函数作为一个完整的解决方案，在您的情况下将是内联验证。
