Vue.js在单击时添加活动类并删除上一个

Question

我想在我的div元素上实现这个活动链接,你可以看到我想用我的代码做的例子

http://jsfiddle.net/fiddleyetu/9ff79/

$(function() {
  $( 'ul.nav li' ).on( 'click', function() {
        $( this ).parent().find( 'li.active' ).removeClass( 'active' );
        $( this ).addClass( 'active' );
  });
});

在这里使用vue.js我不能在我的div元素上做活动链接

这是我的代码,我必须在其中激活链接

    <div class="conversion">
    <div class="file has-text-centered icon-active-color" v-on:click="activeiconc">
        <img src="../imgs/png.png"/>    
        <h4>.PNG</h4>
    </div>
    <div class="file has-text-centered" v-on:click="activeicon" v-bind:class="{ 'icon-active-color':activeiconc,}">
        <img src="../imgs/pdf.png"/>
        <h4>.PDF</h4>
    </div>
    <div class="file has-text-centered" v-on:click="activeicon" v-bind:class="{ 'icon-active-color':activeiconc }">
        <img src="../imgs/jpg.png"/>
        <h4>.JPG</h4>
    </div>
    <div class="file has-text-centered" v-on:click="activeicon" v-bind:class="{ 'icon-active-color':activeiconc }">
        <img src="../imgs/psd.png"/>
        <h4>.PSD</h4>
    </div>
</div>

JS

 export default {
components: {
  MainLayout
},
    data: function(){
    return {
      logo: false,
      color:false,
      list:true,
      grid:false,
      deletebtn:false,
      isImageModalActive: false,
      activerow: false,
      activeiconc:false,
    }
  },
  methods:{ 

    showgrid:function(){
        this.grid = true;
        this.list = false;

    },
    showlist:function(){
        this.list ^=true;
        this.grid = false
    },
    showLogo:function(){
        this.logo ^= true;
        this.color = false; 
        this.deletebtn ^= true;
        this.activerow ^= true
    },
    showColor:function(){
        this.color ^= true;
        this.logo = false;
    },
    activeicon:function(){
        this.activeiconc ^= true;
    }
  }
}

我是Vue的新手,但将JQuery示例转换为Vue.js的简单方法是: Jsfiddle demo

基本上,您需要将活动元素存储在Vue数据中,并根据输入设置类.您可以使用a v-for来呈现列表.

该HTML部分:

<div id="app">
  <ul>
    <li @click="activate(1)" :class="{ active : active_el == 1 }">Link 1</li>
    <li @click="activate(2)" :class="{ active : active_el == 2 }">Link 2</li>
    <li @click="activate(3)" :class="{ active : active_el == 3 }">Link 3</li>
  </ul>
</div>

的Vue.js:

var app = new Vue({
  el:"#app",
  data:{
    active_el:0
  },
  methods:{
    activate:function(el){
        this.active_el = el;
    }
  }
});
