Question

当我尝试运行时，在评论框中输入一些文字后，它不会显示我的评论。为什么？另外我的另一个问题是日志显示

ReferenceError：未定义angular“。

但我已将<script src="js/angular.min.js"></script>链接到我的js文件夹。我的编码出了什么问题？我使用离子cordova创建应用程序，并尝试发表评论，有upvote和downvote。这里是编码：

脚本

angular.module('starter', ['ionic'])

  .run(function($ionicPlatform) {
    $ionicPlatform.ready(function() {
      if (window.cordova && window.cordova.plugins.Keyboard) {
        cordova.plugins.Keyboard.hideKeyboardAccessoryBar(true);

        cordova.plugins.Keyboard.disableScroll(true);
      }
      if (window.StatusBar) {
        StatusBar.styleDefault();
      }
    });
  })

Vue.component('post', {
  template: "#post-template",
  props: ['post'],
  data: function() {
    return {
      upvoted: false,
      downvoted: false
    };
  },
  methods: {
    upvote: function() {
      this.upvoted = !this.upvoted;
      this.downvoted = false;
    },
    downvote: function() {
      this.downvoted = !this.downvoted;
      this.upvoted = false;
    }
  },
  computed: {
    votes: function() {

      if (this.upvoted) {
        return this.post.votes + 1;
      } else if (this.downvoted) {
        return this.post.votes - 1;
      } else {
        return this.post.votes;
      }

    }
  }
});


var vm = new Vue({
  el: "#app",
  data: {
    comments: [{}],
    comment: ""
  },
  methods: {
    postComment: function() {
      this.comments.push({
        title: this.comment,
        votes: 0
      })
      this.comment = "";
    }
  }
});

CSS

a {
  padding-left: 5px;
}

.disabled {
  color: orange;
}


/* some simple transitions to make the upvote and downvote
buttons fade in as a visual cue for the user */

.glyphicon {
  opacity: 1;
  transition: opacity .25s ease-in-out;
  -moz-transition: opacity .25s ease-in-out;
  -webkit-transition: opacity .25s ease-in-out;
}

.glyphicon:hover {
  opacity: 0.75;
  cursor: pointer;
}
