我已经获得了具有此层次结构的Ionic创建者项目：
-index.html
-templates (directory)
--signup.html
--signin.html
-lib (directory)
-css (directory)
-js (directory)
所以...我如何为signup.html页面添加简单的验证？这是所有的signup.html代码，我该如何修改它？我希望所有字段都是强制性的。
<ion-view title="Registrazione" id="page2" style="background-color: rgb(181, 210, 253);">
<ion-content padding="true" scroll="false" class="has-header">

Yeah this is just a demo showing how views can be shown without tabs, then you can navigate
to views within tabs. Additionally, only one set of tabs needs to be written for all of the different views that should go inside the tabs. (Compared to written the same tab links in the footer of every view that's in a tab.)

There's no username/password, just click
the Sign-In button back a the sign-in view.

Return to <a href="#/sign-in">Sign-In</a>.
