Vue adds transportation information

1. Foreword

Nowadays, the logistics industry has become one of the important forces in the development of the national economy. More and more companies have begun to pay attention to the improvement of logistics and improve the efficiency and accuracy of logistics transportation. It has become an inevitable choice for enterprises to optimize logistics management. This article mainly introduces how to use the Vue framework to implement a function that adds transportation information to help you better manage logistics and transportation.

2. Demand Analysis

In the logistics transportation process, in order to facilitate management, we need to record each transportation information, including starting location, destination point, transportation time, transportation status, etc. In addition, we also need to update the transportation information in real time so that we can adjust and follow up in time if any changes occur during the transportation process. Therefore, we need to develop a function to add transportation information. The requirements are as follows:

1. Support users to add transportation information.
2. Transportation information includes the following content: starting point, destination point, transportation time and transportation status.
3. Support users to edit and delete transportation information.
4. Support users to filter based on starting location, destination point, transportation time, and transportation status.

Based on the above requirements, we can choose to use the Vue framework for development.

3. Technical Implementation

1. Create a Vue project

Follow the guidelines of the Vue official documentation and use the Vue CLI command line tool to create a project, including installation Dependencies, configure webpack, etc.

2. Create component

We will add the function of adding transportation information as an independent component and create a Transport component in the Vue project for adding, editing and deleting Shipping information and the ability to filter and display shipping information.

3. Create data model

We need to define a Transport class to store transportation information, including starting location, destination point, transportation time and transportation status.

class Transport {
  constructor (from, to, date, status) {
    this.from = from
    this.to = to
    this.date = date
    this.status = status
  }
}

4. Create data

We use data in Vue to store shipping information and provide some operation methods for data. Define data in the component as follows:

data () {
  return {
   transports: [],  
   newTransport: new Transport('', '', '', '')
  }
}

Among them, transports is used to store all transportation information, and newTransport is used to store a newly added transportation information.

5. Creation method

Next, we need to provide some methods for adding, editing and deleting shipping information. We can define the following methods in methods:

methods: {
  addTransport () {
    this.transports.push(this.newTransport)
    this.newTransport = new Transport('', '', '', '')
  },
  editTransport (index) {
    this.newTransport = Object.assign({}, this.transports[index])
    this.transports.splice(index, 1)
  },
  deleteTransport (index) {
    this.transports.splice(index, 1)
  }
}

Among them, the addTransport method is used to add a piece of transportation information to the transports array, and also clears the contents of newTransport. editTransport and deleteTransport are used to edit and delete transportation information respectively.

6. Display data

Finally, we need to display the stored shipping information in a suitable way. We define the following content in the component's template:

<table>
  <thead>
    <tr>
      <th>起始地点</th>
      <th>目的地点</th>
      <th>运输时间</th>
      <th>运输状态</th>
      <th>操作</th>
    </tr>
  </thead>
  <tbody>
    <tr v-for="(item, index) in transports" :key="index">
      <td>{{item.from}}</td>
      <td>{{item.to}}</td>
      <td>{{item.date}}</td>
      <td>{{item.status}}</td>
      <td>
        <button @click="editTransport(index)">编辑</button>
        <button @click="deleteTransport(index)">删除</button>
      </td>
    </tr>
  </tbody>
</table>

All transportation information will be displayed in the table, and edit and delete buttons will be provided to facilitate user operations.

4. Function Demonstration

After the development of the above steps, we have completely realized the function of adding transportation information. Users can enter the starting point, destination point, transportation time and transportation status on the page, click the "Add" button to add the information to the page, and support editing and deleting transportation information. In addition, we have added a filtering function that allows users to filter based on origin location, destination location, transit time and transit status.

5. Summary

This article introduces how to implement a function to add transportation information under the Vue framework, and realize all operations on transportation information. Through the responsive implementation of the Vue framework and the component-based design idea, the reusability and maintainability of the code have been significantly improved. It should be noted that this article only provides a simple example. In actual business scenarios, it needs to be modified and expanded to varying degrees according to actual needs.
