Steps to reproduce

使用自定义的输入框组，每行有两个输入框，都为required: true。
两个输入框绑定的元素为：names[$key].key, names[$key].value。
点击 号，你可以创建一行数据，-号可以删除。
当第一个输入框内容为空，blur时，会有错误提示，但是影响的是全部一行两个输入框。
如果第一个输入框输入了内容，而第二个为空，会发现第二个输入框的 required:true 并没有错误提示。

What is expected?

同一行的两个输入框的判断应该独立，任何一个为空都可以有单独的错误提示。

What is actually happening?

第一个为空，会影响一行。
第二个为空，无法正确的错误提示。
