How to record the closing status of pop-up windows in Vue.js

In Vue.js development, pop-up windows are one of the frequently used functions. Pop-up windows generally have two states: open and closed. After closing the pop-up window, we usually need to record the status of the current pop-up window so that the previous state can be restored when the pop-up window is opened later. This article will introduce how to record the closing status of pop-up windows in Vue.js.

Problem description

In Vue.js, we can usually use v-show, v-if and other instructions to control the display and hiding of pop-up windows. When a pop-up window is closed, we usually need to record the status of the current pop-up window so that it can be restored to its previous state when the pop-up window is opened again. So, how to record the closing status of the pop-up window?

Solution

Vue.js provides a variety of solutions to record the closing status of pop-up windows. These solutions are introduced below.

Option 1: Use the life cycle hook function of Vue.js

Vue.js provides a variety of life cycle hook functions. We can use these hook functions to record the closing status of the pop-up window.

In the pop-up window component, we can define a data attribute to record the status of the pop-up window:

data() {
  return {
    isClosed: false // 弹窗关闭状态
  }
}

Then, record the closing status of the pop-up window in the beforeDestroy life cycle hook function:

beforeDestroy() {
  this.isClosed = true; // 记录弹窗关闭状态
}

In this way, you can use this state to restore the previous state when the pop-up window is reopened.

Option 2: Use Vuex state management

Vuex is the state management library officially provided by Vue.js. We can use Vuex to record the status of pop-up windows.

In Vuex, we can define a state to record the closing status of the pop-up window:

const state = {
  isClosed: false // 弹窗关闭状态
}

Then, when the pop-up window is closed, we can submit a mutation to change the status:

mutations: {
  closeDialog(state) {
    state.isClosed = true; // 改变弹窗关闭状态
  }
}

In this way, you can use this state to restore the previous state when the pop-up window is reopened.

Option 3: Use localStorage to store status

localStorage is the local storage function provided by the browser. We can use localStorage to store the closing status of the pop-up window.

When the pop-up window is closed, we can save the status to localStorage:

localStorage.setItem('isClosed', true); // 保存弹窗关闭状态

Then, when the pop-up window reopens, we can read the status from localStorage:

const isClosed = localStorage.getItem('isClosed'); // 读取弹窗关闭状态

In this way, you can use this state to restore the previous state when the pop-up window is reopened.

Summary

The above three solutions can all record the closing status of the pop-up window. Which solution to choose depends on the actual situation. If the application is relatively simple and the amount of data is small, you can choose option one or option two; if the application is relatively complex and the amount of data is large, you can choose option three. No matter which solution is adopted, it is very important for developers to record the closing status of pop-up windows, which can improve development efficiency and reduce unnecessary code writing.
