Answer 1

You'd better submit the sample code online and run it. No problem can be seen from the code you provide now

试试，ng-min ng-max

Answer 3

You can set the corresponding style if the form verification succeeds or fails, http://blog.csdn.net/u0111270...

Answer 4

In fact, you can put the input box in one <form></form> 里面，然后给 form 添加一个 name 属性：<form name="myForm"></form>。输入框给一个 ng-model，比如叫 size

By doing this, you can call myForm.size.$valid 来判断是否通过验证。类似的，你也可以从 myForm.size.$error this Object in HTML in real time to get more detailed error information

Use this to dynamically add class 就好，用 ng-class

to the input box
