[Vue] Update Attributes, Classes and Styles in Vue.js with v-bind

JSVue in and with update bind classes
2023-09-14 08:59:19 时间

Use v-bind:class and v-bind:style to compute html classes and inline styles from component data. Vue.js will automatically add vendor prefixes when using v-bind:style.

 

  <body>
    <div id="card">
      <header>{{ title }}</header>
      <button v-bind:class="{'rounded': isRounded, 'large': sizeToggle}"
              v-bind:style="styles" v-bind:disabled="disabled" >Start Tour</button>
      <hr>
      <h4>Options</h4>
      <ul>
        <li><input type="checkbox" v-model="sizeToggle"><label>Large</label></li>
        <li><input type="checkbox" id="round" v-model="isRounded"><label for="round">Rounded</label></li>
        <li><input type="checkbox" v-model="disabled"><label>Disabled</label></li>
        <li><input type="text" v-model="backgroundColor"/><label>Background Color</label></li>
        <li><input type="text" v-model="fontColor"/><label>Font Color</label></li>
        <li><input type="range" v-model="range" min="15" max="85"><label>Position</label></li>
      </ul>
    </div>
    <script src="script.js"></script>
  </body>

</html>

 

var card = new Vue({
  el: "#card",
  data: {
    title: "Style Bindings",
    isRounded: false,
    sizeToggle: false,
    disabled: false,
    backgroundColor: '#CCCCCC',
    fontColor: "#000000",
    range: 50
  },
  computed: {
    styles: function(){
      return {
        color: this.fontColor,
        background: this.backgroundColor,
        'margin-left': this.range+"%"
      }
    }
  }
});

 

body {
  padding: 2em;
  font-family: sans-serif;
}

#card {
  border: 2px solid Gray;
  border-radius: 10px;

.rounded {
