javascript - 需要输入没有 Angular 形式的标签？

Question

我是 angularJS 新手。我有 6 个没有 form 的输入标签。使用点击按钮。我想提出要求；

这里是代码:

     <td><input class="form-control" ng-model="contact.tradeMark" required="string" placeholder="Trade Mark"  ></td>
     <td><input class="form-control" ng-model="contact.applicationNo" placeholder="Application No"></td>
     <td><input class="form-control" ng-model="contact.class" placeholder="Class"></td>
     <td><input class="form-control" ng-model="contact.status" placeholder="Status"></td>
     <td><input class="form-control" ng-model="contact.client" placeholder="Client"></td>
     <td><input class="form-control" ng-model="contact.applicant" placeholder="Applicant"></td>
     <td><input class="form-control" ng-model="contact.remark" placeholder="Remark"></td>

     <td><button class="btn btn-primary" ng-click="addContact()">Add Contact</button></td>
     <td><button class="btn btn-info" ng-click="update()">Update</button>&nbsp;&nbsp;<button class="btn btn-info" ng-click="deselect()">Clear</button></td>

提前致谢

有多种方法可以添加 required input 中的属性字段:

1. Adding required attribute directly -- This is the original HTML way

代码:

<input class="form-control" ng-model="contact.tradeMark" required placeholder="Trade Mark" />

Adding ng-required="true/false" attribute in the field -- This is AngularJS way.

代码:

<input class="form-control" ng-model="contact.tradeMark" ng-required="true" placeholder="Trade Mark" />

Adding ng-required="<some_boolean_condition>".

代码:

<input class="form-control" ng-model="contact.tradeMark" ng-required="isRequired" placeholder="Trade Mark" />

哪里isRequired是 model绑定(bind)在view之间和 controller .
