클릭시 Vue.js 토글 클래스

클릭시 Vue.js 토글 클래스

---

vue.js에서 클래스를 어떻게 토글합니까?

다음이 있습니다.

<th class="initial " v-on="click: myFilter">
    <span class="wkday">M</span>
</th>

new Vue({
  el: '#my-container',
  data: {},
  methods: {
    myFilter: function(){
      // some code to filter users
    }
  }
});

클릭하면 다음과 같이 수업으로 th지원하고 싶습니다 active.

<th class="initial active" v-on="click: myFilter">
    <span class="wkday">M</span>
</th>      

이것은 토글해야합니다. 즉, 클릭 할 때마다 클래스를 추가 / 제거해야합니다.

활성 클래스가 부울 데이터 값에 종속되도록 할 수 있습니다.

<th 
    class="initial " 
    v-on="click: myFilter"
    v-class="active: isActive"
>
   <span class="wkday">M</span>
</th>



    new Vue({
      el: '#my-container',

      data: {
          isActive: false
      },

      methods: {
        myFilter: function(){
            this.isActive = !this.isActive;
          // some code to filter users
        }
      }
    })

---

방법이 필요하지 않습니다.

// html element
<div id="mobile-toggle"
 v-bind:class="{ active: showMobileMenu }"
 v-on:click="showMobileMenu = !showMobileMenu">
</div>

//in your vue.js app
data: {
    showMobileMenu: false
}

이 답변은 Vue.js version 2

<th 
  class="initial " 
  v-on:click="myFilter"
  v-bind:class="{ active: isActive }"
>
  <span class="wkday">M</span>
</th>

Douglas의 나머지 답변은 여전히 ​​적용 가능합니다 (으로 새 Vue 인스턴스 설정 isActive: false등).

요소 외부에서 토글에 액세스 할 필요가없는 경우이 코드는 데이터 변수없이 작동합니다.

<a @click="e => e.target.classList.toggle('active')"></a>

---

이 예제는 Lists를 사용하고 있습니다 : 일부 li를 클릭하면 빨간색으로 바뀝니다.

html :

<div id="app">
  <ul>
    <li @click="activate(li.id)" :class="{ active : active_el == li.id }" v-for="li in lista">{{li.texto}}</li>   
  </ul>
</div>

JS :

var app = new Vue({
  el:"#app",
  data:{
    lista:[{"id":"1","texto":"line 1"},{"id":"2","texto":"line 2"},{"id":"3","texto":"line 3"},{"id":"4","texto":"line 4"},{"id":"5","texto":"line 5"}],
    active_el:0
  },
  methods:{
    activate:function(el){
        this.active_el = el;
    }
  }
});

CSS

ul > li:hover {
  cursor:pointer;
}
.active {
  color:red;
  font-weight:bold;
}

NateW의 답변 외에도 CSS 클래스 이름에 하이픈이있는 경우 해당 클래스를 (작은) 따옴표로 묶어야합니다.

<th 
  class="initial " 
  v-on:click="myFilter"
  v-bind:class="{ 'is-active' : isActive}"
>

 <span class="wkday">M</span>
 </th>

주제에 대한 자세한 내용은 이 주제를 참조하십시오 .

2 개 이상의 수업이 필요한 경우

다음과 같이 할 수 있습니다.

<i id="icon" 
  v-bind:class="{ 'fa fa-star': showStar }"
  v-on:click="showStar = !showStar"
  >
</i> 

data: {
  showStar: true
}

클래스 주위의 작은 따옴표 '를 주목하십시오!

다른 모든 사람의 솔루션 덕분입니다.

prop의 다른 값을 확인할 수있는 솔루션이 있으므로 다른 <th>요소가 활성화 / 비활성화됩니다. vue 2 구문 사용.

<th 
class="initial " 
@click.stop.prevent="myFilter('M')"
:class="[(activeDay == 'M' ? 'active' : '')]">
<span class="wkday">M</span>
</th>
...
<th 
class="initial " 
@click.stop.prevent="myFilter('T')"
:class="[(activeDay == 'T' ? 'active' : '')]">
<span class="wkday">T</span>
</th>



new Vue({
  el: '#my-container',

  data: {
      activeDay: 'M'
  },

  methods: {
    myFilter: function(day){
        this.activeDay = day;
      // some code to filter users
    }
  }
})

new Vue({
  el: '#fsbar',
  data:{
    isActive: false
  },
  methods: {
    toggle: function(){
      this.isActive = !this.isActive;
    }
  }
});
