這是微信小程序的代碼1.if(!this.data.serveItem){ ?????????????? ????????????????????that.setData({? ????????????????????????loadingHide:false ????????????????????}) ?????????????????????//請求服務(wù)項目列表資源 ????????????????????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 ????????????????????}) ????????????????????//?請求評價列表資源 ????????????????????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 ????????????????????}) ????????????????????//?請求推薦列表資源 ????????????????????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段代碼重復(fù)性高，于是我寫了個函數(shù)：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) ????????????} ????????}) ????} }結(jié)果代入?yún)?shù)后提示res is not defined。到底要怎樣寫才不會出錯？

控制臺你看你第幾行報錯了。似乎不是你寫的函數(shù)報錯，估計方法調(diào)來調(diào)去，傳參哪里傳錯了。
