Perkara yang perlu digunakan untuk pemantauan dalam keadaan vue

Status Vue terlalu menggunakan "jam tangan" pendengar untuk pemantauan Melalui pendengar, kemas kini nilai mana-mana sifat berangka boleh dipantau. Pendengar Vue disediakan untuk pembangun memantau perubahan dalam data tertentu dan melaksanakan operasi tertentu berdasarkan perubahan dalam data ini. Perlu diingatkan bahawa pendengar pada dasarnya adalah fungsi Jika anda ingin memantau perubahan dalam data, gunakan data tersebut sebagai nama fungsi.

Persekitaran pengendalian tutorial ini: sistem windows7, versi vue3, komputer DELL G3.

Peralihan Keadaan

Keadaan ialah data, yang merangkumi nilai berangka, nilai warna, nilai atribut, dsb., jadi peralihan keadaan merujuk kepada kesan peralihan data itu sendiri .

Vue mengesyorkan pendekatan "terpacu data, kemas kini responsif" untuk mencapai peralihan keadaan. Idea utama adalah untuk menukar keadaan kepada pembolehubah responsif, dan kemudian menggunakan beberapa perpustakaan dinamik untuk mengemas kini pembolehubah responsif, dengan itu memacu kemas kini responsif Vue dan mencapai kesan dinamik peralihan.

Sistem peralihan Vue menyediakan banyak cara mudah untuk menghidupkan masuk, keluar dan senarai. Bagaimana pula dengan animasi elemen data itu sendiri, seperti:

• Nombor dan operasi
• Paparan warna
• kedudukan nod SVG
• elemen Saiz dan sifat lain

Data ini sama ada disimpan dalam bentuk berangka sendiri atau boleh ditukar kepada nilai berangka. Dengan mengambil kira nilai-nilai ini, kami boleh menggabungkan sistem responsif dan komponen Vue serta menggunakan perpustakaan pihak ketiga untuk melaksanakan keadaan peralihan elemen pensuisan.

1. Animasi status dan pendengar

Melalui pendengar kami boleh memantau kemas kini berangka mana-mana sifat berangka.

Pendengar Vue disediakan untuk pembangun memantau perubahan dalam data tertentu dan melaksanakan operasi tertentu berdasarkan perubahan dalam data ini.

Tetapi sila ambil perhatian: pendengar pada asasnya adalah fungsi Jika anda ingin memantau perubahan dalam data, gunakan data itu sebagai nama fungsi

Ini mungkin kedengaran abstrak lihat contoh menggunakan GreenSock:

<script src="https://cdnjs.cloudflare.com/ajax/libs/gsap/3.2.4/gsap.min.js"></script>

<div id="animated-number-demo">
  <input v-model.number="number" type="number" step="20">
  <p>{{ animatedNumber }}</p>
</div>
<script>
new Vue({
  el: &#39;#animated-number-demo&#39;,
  data: {
    number: 0,
    tweenedNumber: 0
  },
  computed: {
    animatedNumber: function() {
      return this.tweenedNumber.toFixed(0);
    }
  },
  watch: {
    number: function(newValue) {
      gsap.to(this.$data, { duration: 0.5, tweenedNumber: newValue });
    }
  }
})
</script>

Apabila anda mengemas kini nilai, animasi akan dicetuskan. Ini adalah demonstrasi yang baik, tetapi untuk nilai yang tidak boleh disimpan secara langsung seperti nombor, seperti nilai warna dalam CSS, melalui contoh berikut kami menggunakan Tween.js dan Color.js Laksanakan contoh:

<script src="https://cdn.jsdelivr.net/npm/tween.js@16.3.4"></script>
<script src="https://cdn.jsdelivr.net/npm/color-js@1.0.3"></script>
 
<div id="example-7">
  <input
    v-model="colorQuery"
    v-on:keyup.enter="updateColor"
    placeholder="Enter a color"
  >
  <button v-on:click="updateColor">Update</button>
  <p>Preview:</p>
  <span
    v-bind:style="{ backgroundColor: tweenedCSSColor }"
    class="example-7-color-preview"
  ></span>
  <p>{{ tweenedCSSColor }}</p>
</div>
<script>
var Color = net.brehaut.Color
 
new Vue({
  el: &#39;#example-7&#39;,
  data: {
    colorQuery: &#39;&#39;,
    color: {
      red: 0,
      green: 0,
      blue: 0,
      alpha: 1
    },
    tweenedColor: {}
  },
  created: function () {
    this.tweenedColor = Object.assign({}, this.color)
  },
  watch: {
    color: function () {
      function animate () {
        if (TWEEN.update()) {
          requestAnimationFrame(animate)
        }
      }
 
      new TWEEN.Tween(this.tweenedColor)
        .to(this.color, 750)
        .start()
 
      animate()
    }
  },
  computed: {
    tweenedCSSColor: function () {
      return new Color({
        red: this.tweenedColor.red,
        green: this.tweenedColor.green,
        blue: this.tweenedColor.blue,
        alpha: this.tweenedColor.alpha
      }).toCSS()
    }
  },
  methods: {
    updateColor: function () {
      this.color = new Color(this.colorQuery).toRGB()
      this.colorQuery = &#39;&#39;
    }
  }
})
.example-7-color-preview {
  display: inline-block;
  width: 50px;
  height: 50px;
}
</script>

2. Peralihan keadaan dinamik

Sama seperti Vue Seperti komponen peralihan, peralihan keadaan di belakang data akan dikemas kini dalam masa nyata, yang sangat berguna untuk prototaip. Apabila anda mengubah suai beberapa pembolehubah, poligon SVG yang mudah pun boleh mencapai banyak kesan yang tidak dapat dibayangkan.

3 Letakkan peralihan dalam komponen

Menguruskan terlalu banyak peralihan negeri akan meningkatkan bilangan Vue dengan cepat. Contoh atau kerumitan komponen, mujurlah banyak animasi boleh diekstrak ke dalam sub-komponen khusus. Mari kita tulis semula contoh sebelumnya:

<script src="https://cdn.jsdelivr.net/npm/tween.js@16.3.4"></script>
 
<div id="example-8">
  <input v-model.number="firstNumber" type="number" step="20"> +
  <input v-model.number="secondNumber" type="number" step="20"> =
  {{ result }}
  <p>
    <animated-integer v-bind:value="firstNumber"></animated-integer> +
    <animated-integer v-bind:value="secondNumber"></animated-integer> =
    <animated-integer v-bind:value="result"></animated-integer>
  </p>
</div>
<script>
// 这种复杂的补间动画逻辑可以被复用
// 任何整数都可以执行动画
// 组件化使我们的界面十分清晰
// 可以支持更多更复杂的动态过渡
// 策略。
Vue.component(&#39;animated-integer&#39;, {
  template: &#39;<span>{{ tweeningValue }}</span>&#39;,
  props: {
    value: {
      type: Number,
      required: true
    }
  },
  data: function () {
    return {
      tweeningValue: 0
    }
  },
  watch: {
    value: function (newValue, oldValue) {
      this.tween(oldValue, newValue)
    }
  },
  mounted: function () {
    this.tween(0, this.value)
  },
  methods: {
    tween: function (startValue, endValue) {
      var vm = this
      function animate () {
        if (TWEEN.update()) {
          requestAnimationFrame(animate)
        }
      }
 
      new TWEEN.Tween({ tweeningValue: startValue })
        .to({ tweeningValue: endValue }, 500)
        .onUpdate(function () {
          vm.tweeningValue = this.tweeningValue.toFixed(0)
        })
        .start()
 
      animate()
    }
  }
})
 
// 所有的复杂度都已经从 Vue 的主实例中移除！
new Vue({
  el: &#39;#example-8&#39;,
  data: {
    firstNumber: 20,
    secondNumber: 40
  },
  computed: {
    result: function () {
      return this.firstNumber + this.secondNumber
    }
  }
})
</script>

Kita boleh menggunakannya dalam kombinasi dengan komponen Bahagian ini bercakap tentang pelbagai strategi peralihan dan sistem Peralihan terbina dalam Vue . Pendek kata, hampir tiada halangan untuk menyelesaikan pelbagai kesan peralihan.

4. Berikan kehidupan kepada reka bentuk

Hanya satu animasi boleh menghidupkan. Malangnya, apabila pereka bentuk mencipta ikon, logo dan maskot, ia sering dihantar sebagai imej atau SVG statik. Jadi, walaupun kucing sotong GitHub, burung Twitter, dan banyak logo lain menyerupai makhluk hidup, mereka sebenarnya tidak kelihatan hidup.

Vue boleh membantu anda. Memandangkan sifat SVG ialah data, kami hanya memerlukan contoh haiwan ini teruja, berfikir atau berwaspada. Kemudian Vue boleh membantu dalam melengkapkan animasi peralihan antara negeri ini untuk membuat halaman alu-aluan anda, memuatkan arahan dan lebih banyak gesaan emosi.
