陣推方法不能正常工作

Question

我收到以下錯誤的第三行：

Can not set property accountName of Undefined

誰能幫助？

var temp = []; 
temp.accountId = newData.Account.Id; 
temp.accountType = newData.Account.Type; 
temp.accountholder.accountName = newData.Account.Name; 

finaloutput.push(temp); 

Answer 1

提前設置temp.accountholder。

var temp =[]; 
temp.accountId = newData.Account.Id; 
temp.accountType = newData.Account.Type; 
temp.accountholder = {};  
temp.accountholder.accountName = newData.Account.Name; 

finaloutput.push(temp);
