刚学uniapp请教下。我下面的getdata函数哪里定义错了？无法调用
<template> <view>
<view v-for="(item,index) in a2" class="box1" :for="index">
<view :style="item.l11_30==true?'background-color:#FFB9DC':'background-color:#CCCCCC'">
<view class="box2"><text Selection space="ensp">借用时间：{{item.l11_4}} text>view>

首先你要知道uniapp 是基于vue实现的多端兼容的这么一个框架。所以它的写法基本和vue没有区别。vue中定义函数需要写在 methods对象中。还有要养成格式化的习惯...
<script>
export default {
data(){
return{
bga:'#CCCCCC',
bgb:'#FFB9DC',
ac:'true',
a2:[],
}
},
methods:{ // methods包裹函数
getdata (){
//开始请求服务器数据开始
uni.request({
url:'http://localhost/app/1.asp',
data: {
id1:'2',
id2:'addoil',
},
method: 'post',
header: {
'content-type': 'application/x-www-form-urlencoded',
},
success: (res) => {
console.log(res.data)
this.a2 = res.data;
}
})
//开始请求服务器数据结束
},
// 触底的事件
onReachBottom() {
console.log('到了')
// 让页码值自增 +1
//this.queryObj.pagenum += 1
},
onShow: function() {
getData() //调用加载数据方法
},
}
}
</script>
改成下面就不报错。但调用就报错
```bash
<script>
export default {
data(){
return{
a2:[],
}
},
getdata:function(){//开始请求服务器数据开始
uni.request({
url:'http://localhost/app/1.asp',
data: {
id1:'2',
id2:'addoil',
},
method: 'post',
header: {
'content-type': 'application/x-www-form-urlencoded',
},
success: (res) => {
console.log(res.data)
this.a2 = res.data;
}
})
//开始请求服务器数据结束
},
// 触底的事件
onReachBottom() {
console.log('到了')
this.a2=[...this.a2,...[a2]]
// 让页码值自增 +1
//this.queryObj.pagenum += 1
},
onShow: function() {
getData() //调用加载数据方法
},
}
</script>

首先定义方法要写到 methods 中，其次，调用方法要写 this.getData()
