1. Implementation of online assessment

1. Create question bank and test papers:

First, you need to create a question bank and test paper table in the database. The question bank table contains fields such as question content, options, and answers, and the test paper table contains fields such as test paper name and test question ID list.

2. Display questions and options:

In the uniapp page, you can use the v-for command to render questions and options in a loop. Display is achieved by obtaining the question data in the question bank table and then binding it to the page.

3. Submit the answer and score:

After the student selects the answer, click the submit button to transfer the answer to the background for scoring. The background compares the answer field in the test sheet with the answers submitted by the students and calculates the score.

4. Display evaluation results:

According to the scores returned by the background, the page can be displayed differently according to certain rules, such as displaying scores in a percentage system, giving comments, etc.

    </view>
    <button @click="submit">提交答案</button>

<script>
export default {
  data() {
    return {
      questions: [],
      options: [],
      answers: []
    }

    }
  },
  methods: {
    query() {
      // 查询学生成绩的逻辑
    }
  }
}
</script>

The above code examples are for reference only, and the specific implementation can be adjusted according to project requirements and database structure. By implementing online evaluation and performance statistics in uniapp, you can easily digitize education and teaching management functions and improve teaching efficiency and management levels.
