javascript - 非常基本的例子不起作用

Question

有人可以解释一下为什么这个简单的例子不起作用吗？

<script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.2.11/angular.min.js"></script>


<p>{{accountID}}</p>

<input class="form-control input-sm" uib-tooltip="Search by Account ID" validator="/^[0-9]{1,15}$/" validator-invoke="watch" validator-error="Account ID must have 1 to 15 digits." type="number" placeholder="Search by Account ID"
  ng-model="accountID" min="1" required>

Answer 1

您需要将代码包含在 <div ng-app>...</div> 之间标签如下:-

<script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.2.11/angular.min.js"> 
</script>
<div ng-app>
    <p>{{accountID}}</p>
    <input class="form-control input-sm" uib-tooltip="Search by Account ID" validator="/^[0-9]{1,15}$/" validator-invoke="watch" validator-error="Account ID must have 1 to 15 digits." type="number" placeholder="Search by Account ID" ng-model="accountID" min="1" required>
</div>
