How to implement test score query and credit management in uniapp

1. Introduction
In university life, test score query and credit management are very important things . In order to facilitate students' score query and credit management, we can use uniapp, a cross-platform development framework, to implement a simple test score query and credit management system. This article will introduce the specific steps of using uniapp to implement exam score query and credit management, and attach relevant code examples.

2. Examination score query

1. Create page
   First, we need to create a page to display the examination results. In uniapp, we can use the component development method of the Vue framework. To create a page named "score", you can create a new score folder under the pages folder, and then create a score.vue file under this folder. The content of
   score.vue is as follows:

<template>
  <view>
    <text>{{ score }}</text>
  </view>
</template>

<script>
export default {
  data() {
    return {
      score: ""
    };
  },
  onLoad() {
    // 在此处从后台接口获取考试成绩数据，并赋值给score
    // 代码示例：可以使用uni.request或者axios库发送HTTP请求
    uni.request({
      url: "https://api.example.com/score",
      success: res => {
        this.score = res.data.score;
      }
    });
  }
};
</script>

2. Page jump and parameter transfer
   In the page, we can add a button and jump to the test results after clicking the button Query the page and pass the student's student ID as a parameter. You can write the following code in the click event of the button on another page:

uni.navigateTo({
  url: '/pages/score/score?studentId=' + this.studentId
});

In score.vue, we can get the passed student number parameter through the uni.getStorageSync method, and then use the student number Go to the backend to get the corresponding test scores.

onLoad() {
  let studentId = uni.getStorageSync("studentId");
  // 根据学号去后台查询考试成绩，并将结果赋值给score
  // 代码示例：可以使用uni.request或者axios库发送HTTP请求
  uni.request({
    url: "https://api.example.com/score?studentId=" + studentId,
    success: res => {
      this.score = res.data.score;
    }
  });
}

Through the above steps, we can realize the query function of test scores.

3. Credit management

1. Create page
   Create a page named "credit". You can create a new credit folder under the pages folder, and then create a page in this file. Create a credit.vue file under the folder. The content of
   credit.vue is as follows:

<template>
  <view>
    <text>{{ credit }}</text>
  </view>
</template>

<script>
export default {
  data() {
    return {
      credit: ""
    };
  },
  onLoad() {
    // 在此处从后台接口获取学分数据，并赋值给credit
    // 代码示例：可以使用uni.request或者axios库发送HTTP请求
    uni.request({
      url: "https://api.example.com/credit",
      success: res => {
        this.credit = res.data.credit;
      }
    });
  }
};
</script>

2. Page jump
   Add a button to the appropriate page and click the button to jump to the credit management page. You can write the following code in the button click event:

uni.navigateTo({
  url: '/pages/credit/credit'
});

Through the above steps, we can implement the credit management function.

4. Summary
Through uniapp’s cross-platform development framework, we can easily implement test score query and credit management functions. For exam score query, we created a page to display the results, and completed the student number transfer and score query through page jump and parameter transfer. For credit management, we also created a page to display credits and implemented page jumps. Through the above steps, we can implement a simple examination score query and credit management system.

(Note: The interface URL and data structure in the above example are only examples, and need to be modified and adjusted according to the actual situation in actual development.)
