这是微信小程序的代码1.if(!this.data.serveItem){
that.setData({
loadingHide:false
})
//请求服务项目列表资源
wx.request({
url:'https://bird.ioliu.cn/v1?url=http://aasss1.oschina.io/122/4.json',
success(res){
that.setData({
serveItem:res.data,
tireServices: res.data.tireServices,
maintainServices: res.data.maintainServices,
installServices: res.data.installServices,
})
getElementHeight('#item-wrap1',that)
}
})
}2.if(!this.data.rates){
that.setData({
loadingHide:false
})
// 请求评价列表资源
wx.request({
url:'https://bird.ioliu.cn/v1?url=http://aasss1.oschina.io/122/2.json',
success(res){
that.setData({
rates:res.data.rates
})
getElementHeight('#item-wrap2',that)
}
})
}3.if(!this.data.recommendList){
that.setData({
loadingHide:false
})
// 请求推荐列表资源
wx.request({
url:'https://bird.ioliu.cn/v1?url=http://aasss1.oschina.io/122/recommendList.json',
success(res){
that.setData({
recommendList:res.data.recommendList
})
getElementHeight('#item-wrap3',that)
}
})
}上面3段代码重复性高，于是我写了个函数：function requestResouce(that,oldObj,newObj,url,id){
if(!oldObj){
that.setData({
loadingHide:false
})
wx.request({
url:url,
success(res){
that.setData(newObj)
getElementHeight(id,that)
}
})
}
}结果代入参数后提示res is not defined。到底要怎样写才不会出错？
