Passing vue.js store data to a event click handler

I am using regular Vue.js in my project. I store data in a store made from scratch and use it in a template:

<template>
  <div>
    <div class="row">
      <div v-for="(picture, index) in storeState.pictures"
          :key="index"
          class="col-md-2 my-auto">   
          <div >                 
            <img class="img-thumbnail img-responsive" 
                :src="picture.url"
                @click="deleteMe">            
          </div>              
      </div>      
    </div>    
    </div>
</template>

<script>
import { store } from "../common/store.js"

export default {
  name:"PictureUpload",
    data() {
        return {
  storeState: store.state,           
        };
  },
  methods: {
    deleteMe() {
      let apiUrl = this.picture.url
      console.log(apiUrl)
    }
  }
}
</script>

My pictures are rendering well but now I want to add a delete() function to the picture @click and whenever I click on the button I get:

TypeError: Cannot read property 'url' of undefined

So how can I access my picture data inside my method?

Answer

You should pass picture as parameter in the click handler :

  @click="deleteMe(picture)">

and refer to it in the method like :

 methods: {
   deleteMe(picture) {
     let apiUrl = picture.url //omit this
     console.log(apiUrl)
    }
   }

the storeState should be a computed property :

export default {
  name:"PictureUpload",
    data() {
        return {
           
        };
  },
  computed:{
     storeState(){
    return store.state;
   }
  },
  methods: {
    deleteMe(picture) {
      let apiUrl = picture.url
      console.log(apiUrl)
    }
  }
}
