Vue.js 在挂载中运行代码并再次运行以实现重新启动功能 [英] Vue.js run a code in mounted and again for restart functionality

问题描述

我正在 VueJS 中创建一个游戏，当页面加载时，我想要一个方法来触发，对外部 API 进行 ajax 调用并创建一堆数据属性.当玩家赢得这一轮时，我希望他们能够看到一个按钮，让他们可以重新开始游戏.我正在使用 mounted() 钩子在页面加载时触发该方法.

I am creating a game in VueJS, where, when the page loads, I want a method to fire, make an ajax call to an external API and create a bunch of data properties. When the player wins the round, I want to them to be able to see a button that allows them to restart the game. I am using a mounted() hook to fire the method on page load.

我的问题是，如果游戏设置和 API 调用在 mounted() 函数内，我不确定如何实现重启功能.有没有办法再次运行mounted()函数?

My question is I am not sure how to implement the restart functionality if the game setup and API call are within the mounted() function. Is there a way to run the mounted() function again?

推荐答案

将您的初始化抽象为一个方法，并从 mounted 和您想要的任何其他地方调用该方法.

Abstract your initialization into a method, and call the method from mounted and wherever else you want.

new Vue({
  methods:{
    init(){
      //call API
      //Setup game
    }
  },
  mounted(){
    this.init()
  }
})

然后可能在您的模板中有一个按钮可以重新开始.

Then possibly have a button in your template to start over.

<button v-if="playerWon" @click="init">Play Again</button>

在此按钮中，playerWon 表示您数据中的一个布尔值，您将在玩家赢得游戏时设置该值，以便显示该按钮.您可以在 init 中将其设置回 false.

In this button, playerWon represents a boolean value in your data that you would set when the player wins the game so the button appears. You would set it back to false in init.
