为什么
ng-app="myApp"
导致表达式不求值?
如果我用
ng-app=""
,工作正常:
<!DOCTYPE html>
<html>
<head>
</head>
<script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.6.9/angular.min.js"></script>
<body>
<div ng-app="" ng-init="quantity=2;price=5">
<h2>Cost Calculator</h2>
Quantity: <input type="number" ng-model="quantity">
Price: <input type="number" ng-model="price">
<p><b>Total in dollar:</b> {{quantity * price}}</p>
</div>
</body>
</html>
