I want the orderID to the mutation cancelOrder then let it do something.
Here is my code for app.vue:

<template>
...codes
<tbody v-for="item in $store.state.orders">
            <tr  v-if="item.status === 0">
                <th scope="row">{{item.orderID}}</th>
                <td>{{item.orderDeskNumber}}</td>
                <td>{{item.orderTime}}</td>
                <td>
                    <p>{{item.orderStuff}}&nbsp;*&nbsp;{{item.orderCount}}</p>
                    <p v-if="item.orderStuff1">{{item.orderStuff1}}&nbsp;*&nbsp;{{item.orderCount1}}
                    </p>
                    <p v-if="item.orderStuff2">{{item.orderStuff2}}&nbsp;*&nbsp;{{item.orderCount2}}
                    </p>
                    <p v-if="item.orderStuff3">{{item.orderStuff3}}&nbsp;*&nbsp;{{item.orderCount3}}
                    </p>
                    <p v-if="item.orderStuff4">{{item.orderStuff4}}&nbsp;*&nbsp;{{item.orderCount4}}
                    </p>
                </td>
                <td >
                    <el-button type="danger" @click="cancelOrder(item.orderID)">取消</el-button>
                    <el-button type="success">结账</el-button>
                </td>

            </tr>
        </tbody>
...codes

Here is the method function:

cancelOrder(id) {
//console.log('this id is '   id)
            this.$store.commit('cancelOrder', id)
        }

Here is the mutation code:

async cancelOrder(payload) {
      console.log('i got id from app.vue'   payload)
      await axios.post('someurl', { some params, id: payload }, { timeout: 1000 }).then((res) => {
        console.log('somethin')
      }).catch((err) => {
        console.log('something'   err.message)
      }) */
    },

If I clicked one of those buttons, I found that console outputs are:

this id is 2
i got id from app.vue is [object,Object]

        }
    ],
    "payload": {}
}

But why? I passed only the number 1 to mutation, but why it got a full object?
Please help, thanks!

CodePudding user response：

The first parameter of the mutation is the state and the second parameter is what you pass. You have only one parameter so what you are looking at is the state object.

Change async cancelOrder(payload) { to async cancelOrder(state, payload) {
