Question

返回有关Mongo和LiveCode的更多问题，这次是针对MergJSON的特定问题。

情况如下：在previous posts中，我询问了一些关于如何连接并从查询中获取结果的问题，并回答了问题。

现在我在LiveCode字段中返回了Mongo返回的文档（用于验证目的）。

这是退回的文件：

    { "_id" : "001003", "nombre" : "Pedro" }
    { "_id" : "001004", "nombre" : "Alejandro" }
    { "_id" : "001005", "nombre" : "Mario" }
    { "_id" : "001001", "nombre" : "Javier" }
    { "_id" : "001002", "nombre" : "Andrecillo" }

我现在想要什么，而且无法工作就是这样，我的堆栈有一个按钮脚本我有一个鼠标处理程序：

on mouseUp
    local dbText, dbResultado
    set the hideConsoleWindows to true
    put "var c=db.nueva.find();" into dbText
    put " while(c.hasNext())" after dbText
    put " printjson(c.next())" after dbText
    put shell("C:\mongodb\bin\mongo.exe --eval" && quote & dbText & quote) into dbResultado
    put line 3 to -1  of dbResultado into pJSON
    put  pJSON  into  field "A"  -- just to see what Mongo is returning after eliminating       line 1 and 2 of dbResultado
    put JSONToArray(pJSON) into tArray
    put tArray["nombre"] into fld "B"
end mouseUp

此处理程序之后是Decode和Encode函数。

运行此脚本时出现错误：

     executing at 10:15:18 AM
     Type   could not decode JSON: end of file expected near '{'
     Object Mejoraddo
     Line   repeat for each line tKey in mergJSONDecode(pJSON,"tArray")
     Hint   could not decode JSON: end of file expected near '{'

在这行函数中JSONToArray pJSON：

     repeat for each line tKey in mergJSONDecode(pJSON,"tArray")

我几乎可以肯定我错过了一个简单的步骤或监督明显的事情。如果您需要澄清一下，请我试着更好地解释一下，提前谢谢，

不是JSON：

{ "_id" : "001003", "nombre" : "Pedro" }
{ "_id" : "001004", "nombre" : "Alejandro" }
{ "_id" : "001005", "nombre" : "Mario" }
{ "_id" : "001001", "nombre" : "Javier" }
{ "_id" : "001002", "nombre" : "Andrecillo" }

JSON：

[
  { "_id" : "001003", "nombre" : "Pedro" },
  { "_id" : "001004", "nombre" : "Alejandro" },
  { "_id" : "001005", "nombre" : "Mario" },
  { "_id" : "001001", "nombre" : "Javier" },
  { "_id" : "001002", "nombre" : "Andrecillo" }
]

请参阅the JSON docs

尝试：

local tIndex = 1
repeat for each line tJSON in line 3 to -1  of dbResultado
    put JSONToArray(tJSON) into tArray[tIndex]
    add 1 to tIndex
end repeat
put tArray[1]["nombre"] into fld "B"
