這篇文章主要介紹了vue.js 實現(xiàn)點擊div標(biāo)簽時改變樣式，具有很好的參考價值，希望對大家有所幫助。如有錯誤或未考慮完全的地方，望不吝賜教

1.點擊某一項后樣式發(fā)生改變(循環(huán)列表的每一項的樣式改變)

效果圖

v-for循環(huán)展示productType中的數(shù)據(jù)

：class動態(tài)綁定樣式表中.changeStyle的樣式，將當(dāng)前索引傳遞給changeSelectStyle

@click點擊事件觸發(fā)函數(shù)changeStyle(),并將當(dāng)前索引傳遞進(jìn)去。

<ul v-for="(item,index) in productType" :key="index">
   <li  class="type-name" :class="{changeStyle:changeSelectStyle == index}" 
                         @click="changeStyle(index)" >{{item.name}}</li>
</ul>

 data(){
    return{
      changeSelectStyle:'',
      productType:[
        {"name":"APE1"},
        {"name":"APE2"},
        {"name":"APE3"},
        {"name":"APE4"},
      ]
  }
}

樣式表：

.type-name
    height 38px
    text-align center
    line-height 38px 
.changeStyle
    color #0099cc
    background-color #fff

changeStyle方法：

讓changeSelectStyle的值為當(dāng)前索引的值

    changeStyle:function(index){
      this.changeSelectStyle = index;
    },

2.切換樣式應(yīng)該是v-bind很常用的功能(單標(biāo)簽樣式的改變)

 <div class="selectAll" :class="{selectAll: !isshow,changeSelectAll: isshow}" @click="isshow=!isshow">
          <div class="text-header">全部</div>
          <div class="sel-icon"></div>
</div>

 data(){
    return{
      isshow: true
}

點擊后改變文字顏色和圖標(biāo)

.selectAll 
    flex 0 0 37px 
    display flex   
  .text-header
    padding-left 23px 
    flex 0 0 240px 
    border-left 1px solid #0099cc
    border-bottom 1px solid #f7f7f7
    letter-spacing 2px
    line-height 37px 
  .sel-icon
    flex 1
    bg-image('../images/select-icon2')
    background-repeat no-repeat 
    background-size 16px 16px
    width 16px 
    height 16px 
    align-self center
.changeSelectAll
    color #0099cc 
   .sel-icon
    bg-image('../images/select-icon1')

原圖及點擊后效果

3.實現(xiàn)聯(lián)動（完整代碼）

效果如下：

默認(rèn)狀態(tài)，循環(huán)列表的每一項都沒有被選中。選中后其中某一項全部取消，選中全部，其他項取消選中。

 <div class="fliter-container">

     <span class="back-icon" @click="back()"/>
     <p class="title">產(chǎn)品篩選</p>
   </div>
   <div class="content">
      <div class="left">
        <ul v-for="(item,index) in productType" :key="index">
          <li  class="type-name" :class="{changeStyle:changeSelectStyle == index}" @click="changeStyle(index)" >{{item.name}}</li>
        </ul>
      </div>
      <div class="right">
        <div class="selectAll" :class="{selectAll: !isshow,changeSelectAll: isshow}" @click="isshow=!isshow">
          <div class="text-header">全部</div>
          <div class="sel-icon"></div>
        </div>
        <div class="select-detail" >
