Question

我正在学习角度的过程。当我执行下面的代码时

<!doctype html>
<html lang="en">
<head>
  <meta charset="UTF-8">
  <title>Example - example-guide-concepts-1-production</title>


  <script src="//ajax.googleapis.com/ajax/libs/angularjs/1.3.0-rc.0/angular.min.js"></script>



</head>
<body >
      <div ng-app ng-init="qty=1;cost=2">
      <b>Invoice:</b>
      <div>
        Quantity: <input type="number" min="0" ng-model="qty">
      </div>
      <div>
        Costs: <input type="number" min="0" ng-model="cost">
      </div>
      <div>
        <b>Total:</b> {{qty * cost | currency}}
      </div>
    </div>
</body>
</html>

呈现的代码显示{{qty * cost |货币}}。角度没有加载到浏览器（chrome）？我检查了角度的版本，看起来没问题。感谢。

很可能你没有正确加载角度js。

使用您的代码检查此plunker，这是有效的。

<!DOCTYPE html>
<html>

  <head>
    <script data-require="angular.js@*" data-semver="1.3.0-beta.5" src="https://code.angularjs.org/1.3.0-beta.5/angular.js"></script>
    <link rel="stylesheet" href="style.css" />
    <script src="script.js"></script>
  </head>

  <body>
    <div ng-app ng-init="qty=1;cost=2">
        <b>Invoice:</b>
        <div>
            Quantity:
            <input type="number" min="0" ng-model="qty">
        </div>
        <div>
            Costs:
            <input type="number" min="0" ng-model="cost">
        </div>
        <div>
            <b>Total:</b> {{qty * cost | currency}}
        </div>
    </div>
</body>

</html>

角度代码显示在页面中
