點擊 v-for Div 獲取 object 數據

Question

我有一個帶有 v-for 的 div，我想獲得我單擊的 div 的 object 值。 當我單擊帶有警報的 div 時，我嘗試在數據中顯示，但它不起作用。 你能幫我解決這種情況嗎？

<div id="ticketContent" v-for="ticket in tickets" @click="getTicketInformations">
              <h5> Ticket : {{ ticket.ticketID }}</h5>
              <p>Ticket Number : {{ticket.ticketNumber}}</p>
              <p>Start Date : {{ticket.startDate}}</p>
              <p>Expire Date : {{ticket.expireDate}}</p>
              <p>Hours : {{ ticket.hours }} </p>
            </div>

state : {
   tickets :[
            {"ticketID":1001,
            "ticketNumber":"2783sA",
            "startDate":"05/10/2018",
            "expireDate":"10/21/2022",
            "hours":"08:00-22:00"},
            {"ticketID":1002,
            "ticketNumber":"8a210j",
            "startDate":"01/03/2018",
            "expireDate":"01/03/2020",
            "hours":"14:00-18:00"},
            {"ticketID":1003,
            "ticketNumber":"L90Np1",
            "startDate":"10/01/2015",
            "expireDate":"10/01/2020",
            "hours":"10:00-20:00"},
            {"ticketID":1004,
            "ticketNumber":"L90Np1",
            "startDate":"05/01/2015",
            "expireDate":"05/01/2016",
            "hours":"15:00-23:00"}],
}
<script>
import { mapGetters } from 'vuex';

export default {
    computed: {
      ...mapGetters({
        tickets : 'tickets'
      }),
    },
    methods : {
      getTicketInformations(){
        alert(ticket)
      }
    }
}
</script>

Answer 1

嘗試這個：

改變 vfor

<div id="ticketContent_(index)" v-for="(ticket, index) in tickets" @click="getTicketInformations(index)">

和方法：

getTicketInformations(index){
        alert("clicked on ->" + document.getElementById(ticketContent_' + index + '))
      }

Answer 2

您可以將 selectedTicket 屬性添加到 model 中，然后在單擊事件中將票證實例傳遞給 showTicket 方法。

 <script src="http://unpkg.com/vue"></script> <style>.ticket{padding:5px; border-bottom:1px solid lightblue} </style> <div id="app" style="width:100vw"> Tickets: <div class="ticket" v-for="ticket in tickets" v-bind:key="ticketID" @click="showTicket(ticket)"> {{ticket.ticketNumber}} </div> <br/> Selected Ticket: <div>{{selectedTicket}}</div> </div> <script> new Vue({ el: "#app", data() { return { selectedTicket: null, tickets: [ { "ticketID": 1001, "ticketNumber": "2783sA", "startDate": "05/10/2018", "expireDate": "10/21/2022", "hours": "08:00-22:00" }, { "ticketID": 1002, "ticketNumber": "8a210j", "startDate": "01/03/2018", "expireDate": "01/03/2020", "hours": "14:00-18:00" } ] } }, methods: { showTicket(ticket) { this.selectedTicket = ticket; } } }) </script>
