我正在尝试使用Q卡遍历客户信息阵列。我已经进行测试,以确保我的客户数组始终得到更新,并具有从NodeJS服务器获得的值,但是它拒绝显示任何Q卡。我已经尝试了很多东西,但根本无法使它工作。任何建议或意见将是巨大的。预先感谢
<template>
<div id="maincustomer">
<div id="customerbox">
<div class="row">
<q-input class="inputspace" placeholder="First Name" color="secondary" v-model="fname" @input="dataentered()"/>
<q-input class="inputspace" placeholder="Last Name" color="secondary" v-model="lname" @input="dataentered()"/>
<q-btn class="inputspace" icon="search" color="secondary" :disable="buttonenable" @click="findcustomer()"/>
</div>
<div class="row">
<q-card color="secondary" dark class="q-ma-sm" v-for="customer in customers" :key="customer.CustomerID">
<q-card-title>
{{ customer.FirstName }} {{ customer.LastName }}
<span slot="subtitle">Phone Number: {{ customer.PhoneNumber }}</span>
<q-icon slot="right" name="person" />
</q-card-title>
<q-card-main>
{{ customer.Address }}
</q-card-main>
<q-card-separator />
</q-card>

答案 0 :(得分:0)
可能您在这里丢失了this
上下文:
function(customerlist) {
console.log(customerlist)
this.customers=customerlist
}
因为function
有自己的this
上下文。要修复它,您应该使用箭头功能。对于您的情况:
findcustomer() {
this.$Socket.emit('findcustomer', {
fname: this.fname,
lname: this.lname
}, (customerlist) => {
console.log(customerlist)
this.customers=customerlist
}
)
}
