在日冕顯示JSON數據頁明智

Question

我從JSON檢索數據，但整個數據顯示在我的頁面上， 但我想明智地顯示它，例如。第一頁1到10， 和當用戶按下按鈕，其餘的記錄顯示，我工作 那，但不能解決它，是否有任何概念的電暈， 或請提供對於這個問題，感謝幫助..

這裏是我的JSON數據結構：

My code for displaying JSON data: 



local test=json.decode(event.response) 
    local datas=test.data 
    for name, users in pairs(datas) do 
     for names, usernames in pairs(users) do 
      for tag,value in pairs(usernames) do 
      cid=value.customerid 
      cname=value.customername 
      print(cname) 
      print(cid) 
      end 
     end 
    end

這是要顯示明智頁的json數據

Answer 1

這裏是你如何能得到您的JSON數據暗示我只是得到了第一和最後一個名字在這裏，我只是複製您的JSON數據並把它放在一個文本文件名數據

local json = require "json" 
local txt 
local path = system.pathForFile("data.txt", system.ResourceDirectory) 
data = {} 
local file = io.open(path, "r") 
if file then 
     -- read all contents of file into a string 
     txt = file:read("*a") 
     io.close(file) -- close the file after using it 
end 

local t = json.decode (txt) 



for i = 1, table.getn(t["data"]["marks"]), 1 do 

print(t["data"]["marks"][i]["Marks"]["first_name"]) 
print(t["data"]["marks"][i]["Marks"]["last_name"]) 


end

上面的示例代碼僅僅是將照片傾印到控制檯上。我假設你最終想要在屏幕上實際顯示它。我會建議使用一個widget.newTableView（）並讓系統爲你處理滾動。
