Vue-cli框架實現(xiàn)計時器應(yīng)用

 更新時間：2021年08月06日 14:25:16   作者：Chernyang  
這篇文章主要為大家詳細介紹了Vue-cli框架實現(xiàn)計時器應(yīng)用，文中示例代碼介紹的非常詳細，具有一定的參考價值，感興趣的小伙伴們可以參考一下

技術(shù)背景

本應(yīng)用使用 vue-cli 框架，并使用了自定義組件（將按鈕拆分成單獨的組件）和vue 模板。

使用說明

開始正計時：點擊工具欄的“開始正計時”按鈕即可，快捷鍵為"Enter"鍵。

開始倒計時：在輸入框內(nèi)寫入時間后，點擊“開始倒計時”按鈕，即可開始倒計時。

暫停計時器：點擊“暫停計時器”按鈕即可暫停。

清空正/倒計時：點擊此按鈕，計時器便會回到初始狀態(tài)，等待新的計時。

重新再計時：點擊此按鈕，計時器便會重新開始此次計時。

恢復(fù)計時器：點擊此按鈕即可從暫停狀態(tài)中恢復(fù)。

代碼

首先初始化項目

vue init webpack <project name>

components文件夾中放入文件：CounterButton.vue

<template>
  <div>
    <button v-bind:class="styleObject" v-on:click="$emit('click-button')">{{ text }}</button>
  </div>
</template>

<script>
export default {
  name: "CounterButton",
  props: {
    text: String
  },
  data: function() {
    return {
      styleObject: {
        countup: false,
        countdown: false,
        clear: false,
        pause: false,
        restart: false,
        resume: false
      }
    };
  },
  created: function() {
    if (this.text == "開始正計時") {
      this.styleObject.countup = true;
    } else if (this.text == "開始倒計時") {
      this.styleObject.countdown = true;
    } else if (this.text == "清空倒計時" || this.text == "清空正計時") {
      this.styleObject.clear = true;
    } else if (this.text == "暫停計時器") {
      this.styleObject.pause = true;
    } else if (this.text == "重新再計時") {
      this.styleObject.restart = true;
    } else if (this.text == "恢復(fù)計時器") {
      this.styleObject.resume = true;
    }
  }
};
</script>

<style>
.countup {

}

.countdown {
  background-color: #2188e9;
  border-radius: 5px;
  border-color: #2188e9;
  position: absolute;
  left: 428px;
  top: 15px;
  width: 98px;

}

.clear {

  font-family: PingFangSC-Regular, "PingFang SC", sans-serif;
  font-size: 16px;

}

.pause {
  background-color: #2188e9;
  border-radius: 5px;
  border-color: #2188e9;
  position: absolute;
  left: 227px;

  width: 98px;
  height: 40px;
  font-family: PingFangSC-Regular, "PingFang SC", sans-serif;
  font-size: 16px;
  color: #ffffff;
}

.restart {
  background-color: #ffb020;
  border-radius: 5px;
  border-color: #ffb020;
  position: absolute;

}

.resume {
  background-color: #2188e9;
  border-radius: 5px;
  border-color: #2188e9;
  position: absolute;
  left: 227px;

  height: 40px;
  font-family: PingFangSC-Regular, "PingFang SC", sans-serif;

}
</style>

將App.vue改為

<template>
  <div id="app">
    <div class="toolbar">
      <div v-show="initialSeen">
        <input v-model="hour" id="hour" />

        <input v-model="second" id="second" />

        <span id="hourlabel">時</span>

        <span id="minutelabel">分</span>

        <span id="secondlabel">秒</span>

        <counter-button text="開始正計時" v-on:click-button="startCountUp" id="countup"></counter-button>

        <counter-button text="開始倒計時" v-on:click-button="startCountDown" id="countdown"></counter-button>
      </div>

      <span id="hint" v-show="hintSeen">{{ hint }}</span>

      <counter-button v-bind:text="clearText" v-on:click-button="clearCounter" v-show="clearSeen" id="clear"></counter-button>
      <counter-button text="暫停計時器" v-on:click-button="pauseCounter" v-show="pauseSeen" id="pause"></counter-button>
      <counter-button text="重新再計時" v-on:click-button="restartCounter" v-show="restartSeen" id="restart"></counter-button>
      <counter-button text="恢復(fù)計時器" v-on:click-button="resumeCounter" v-show="resumeSeen" id="resume"></counter-button>
    </div>
    <span id="time">{{ time }}</span>
