The golden combination of Vue and Excel: How to implement dynamic filtering and export of data

Introduction: Vue.js is a popular JavaScript framework that is widely used to build dynamic user interfaces. Excel is a powerful spreadsheet software used to process and analyze large amounts of data. This article will introduce how to combine Vue.js and Excel to implement dynamic filtering and exporting of data.

1. Dynamic data filtering

Dynamic data filtering is a common requirement, which enables users to filter data based on specific conditions. In Vue.js, this functionality can be achieved through computed properties and conditional rendering.

First, we need to prepare a set of data, such as an array containing student information:

data() {
  return {
    students: [
      { name: '张三', age: 18, gender: '男' },
      { name: '李四', age: 20, gender: '女' },
      { name: '王五', age: 19, gender: '男' },
    ],
    filter: '',
  }
},

Next, we can use calculated properties to dynamically obtain data based on filter conditions:

computed: {
  filteredStudents() {
    return this.students.filter(student => {
      return student.name.includes(this.filter) ||
             student.age.toString().includes(this.filter) ||
             student.gender.includes(this.filter);
    });
  }
},

In the HTML template, we can use v-model to bind the input box of the filter condition, and use the v-for instruction to loop to render the filtered data:

<input type="text" v-model="filter" placeholder="输入过滤条件">
<table>
  <tr v-for="student in filteredStudents" :key="student.name">
    <td>{{ student.name }}</td>
    <td>{{ student.age }}</td>
    <td>{{ student.gender }}</td>
  </tr>
</table>

In this way, the user can Enter filter conditions in real time and only display data that meets the conditions.

2. Export data to Excel

In some cases, we may need to export the data to Excel for further analysis. Fortunately, Vue.js provides some tools and libraries to easily implement data export functionality.

First, we need to install a JavaScript library called xlsx. You can use npm or download the files for this library directly.

Next, we can create a method to export data to Excel:

methods: {
  exportToExcel() {
    const XLSX = require('xlsx');
    
    const worksheet = XLSX.utils.json_to_sheet(this.students);
    const workbook = XLSX.utils.book_new();
    XLSX.utils.book_append_sheet(workbook, worksheet, "学生信息");
  
    XLSX.writeFile(workbook, "学生信息.xlsx");
  }
},

In the HTML template, we can add a button and call exportToExcel when clicked Method:

<button @click="exportToExcel">导出到Excel</button>

Now, when the user clicks the button, an Excel file named "Student Information.xlsx" will be automatically downloaded, which contains the information of all students.

Conclusion: Combining Vue.js and Excel can realize dynamic filtering and exporting of data, making data processing more convenient and faster. Through this golden combination, we can better meet users' needs for data operations and provide a better user experience.
