javascript - Vue for loop for objects not working -


i trying create top menu dropdown buttons when iterating on object looks this:

links: {       store: 'store',       language: [{'target': '/english'},{'target': '/norwegian'}],       login: 'user/login'     }

i have tried achieve making loop looks this:

       <div v-for="(value, key) in links" :key="key" class="control">             <div v-if='array.isarray(value)'>                 <dropdown-menu :menu="value"></dropdown-menu>             </div>             <div v-else>                 <a :href="value">                     {{ key }}                 </a>             </div>         </div>

but, errors:

property or method "value" not defined on instance referenced during render. make sure declare reactive data properties in data option.

even if declare value , key initial values of null, not rendering anything:

data() {   return {     data: null,     value: null,     key: null,   }; },

this dropdown menu component:

<template>   <div class="dropdown is-active">     <div class="dropdown-trigger">       <button class="button" aria-haspopup="true" aria-controls="dropdown-menu">         <span>dropdown button</span>         <span class="icon is-small">           <i class="fa fa-angle-down" aria-hidden="true"></i>         </span>       </button>     </div>     <div class="dropdown-menu" id="dropdown-menu" role="menu">       <div class="dropdown-content">         <a href="#" class="dropdown-item">           dropdown item         </a>         <a class="dropdown-item">           other dropdown item         </a>         <a href="#" class="dropdown-item is-active">           active dropdown item         </a>         <a href="#" class="dropdown-item">           other dropdown item         </a>         <hr class="dropdown-divider">         <a href="#" class="dropdown-item">           divider         </a>       </div>     </div>   </div> </template>  <script>   export default {     name: 'dropdown-menu',     props: ['menu'],     data() {       return {};     },   }; </script>

but, dropdown menu not shown in vue dev tools when go top-bar component.

update

for reason if removed divs, , changed template this:

<dropdown-menu v-if='array.isarray(value)' :menu="link"></dropdown-menu> <a :href="value" v-else>      {{ key }} </a>

if explain it, great.
