使用带有选择标记的@click方法来更改计算属性的值

Question

我想做的是：

在文本框中输入情感，并在选择框中输入情感的强度。蓝色按钮增添了情感。
在重估部分，我想重估那种情绪的强度。

在重新计算中，我正在遍历计算的属性rerateEmotions，该属性具有包含emotion和intensity属性的对象数组。我想做的是使用select标签更改计算属性上每种情感的强度：

[好，我发现我需要在重新定价@click上将@change更改为<select>

现在，我只想弄清楚如何从“评价情感”和“评价情感”区域中获得单独的评分。

const app = new Vue({
  el: "#app",
  data: function() {
    return {
      emotion: "",
      intensity: null,
      newIntensity: null,
      emotionIntensity: []
    };
  },
  computed: {
    rerateEmotions() {
      return this.emotionIntensity;
    }
  },
  methods: {
    rerateIntensity(id) {
      return (this.rerateEmotions[id].intensity = this.newIntensity);
    },
    openEmotion(id) {
      this.emotionId = id;
    },
    addEmotionIntensity() {
      var emotionIntensity = {
        emotion: this.emotion,
        intensity: this.intensity
      };
      this.emotionIntensity.push(emotionIntensity);
      this.emotion = "";
      this.intensity = null;
    },
    removeEmotion(id) {
      if (id > -1) {
        this.emotionIntensity.splice(id, 1);
      }
    },
  }
});
