javascript - 我在vue中的v-for裡綁定事件報錯?

Question

我在v-for裡面循環產生route-link，想給他綁定一個事件，結果報錯說事件未定義，下面是我的程式碼

    <ul class="card-list">
      <li v-for="(url, index) in urls">
        <router-link class="linkTo" :to="'/Page' + (index + 1)">
          <img @click="total(index)" class="cardWidth" :src="url" alt="">
        </router-link>
      </li>
    </ul>
    
    method: {
      total: function (index) {
        console.log(index)
      }
    }
    
    

報錯訊息:

Property or method "total" is not defined on the instance but referenced during render. Make sure to declare reactive data properties in the data option. 
Uncaught TypeError: _vm.total is not a function

Answer 1

是 methods

http://vuejs.org/v2/api/#methods

Answer 2

沒有定義total這個方法，樓下正確
