how to convert into a json object - json

Question

i have a file named 'funcJson.json'
whose content are as follows:
{
"fid":{
"processDate":function ()
{
data=MainMasterarr;
for(var i=0;i<data.length;i++)
{
data[i]['_id'] =data[i]['_id'].substring(0,8);
var mongoId = data[i]["_id"];
var dateObject = new Date( mongoId );
dateObject = new Date( parseInt( mongoId, 16 ) * 1000 );
var date = dateObject.getDate();
var month = dateObject.getMonth()+1;
var year = dateObject.getFullYear().toString();
var yearSub = year.substring(2,4);
if(month<10)
month='0'+ month;
if (date<10)
date='0'+ date;
var dateString = month+'/'+date+'/'+yearSub;
data[i]['fid'] = dateString;
}
} ,
"consoleDate":function ()
{
data=MainMasterarr;
console.log(data[0]['fid']);
}
}
}
now i trying to read this file and convert the file content to json object.
when i equate the above json to a variable.it works like json object but now when i m trying to read it from a file it throws error.
my client side code is below:
function fetchFileData(fn,callback)
{
var fileName='funcJson.json';
var request = new goog.net.XhrIo();
var data = goog.Uri.QueryData.createFromMap(new goog.structs.Map({
"fileN":fileName,
}));
goog.events.listen(request, "complete", function()
{
if (request.isSuccess())
{
if(request.getResponseText() == 'fails')
{
callback("error");
return;
} //if response fails
else
{
var response = request.getResponseJson();
fileData=response;
console.log(fileData);
callback(response);
}//else
} //if request is success
});//listen event
request.send(fetchFileUrl, "POST", data);
//return fileData;
};
and server side code is as follows
function fetchFile(req,res,params)
{
var fs = require('fs');
//var configJson = {};
var fileName=params.fileN;
fs.readFile(fileName, 'utf8', function (err, data) {
if (err)console.log(err);
//console.log(data);
//configJson = JSON.parse(data);
res.writeHead(200, {
"Content-Type": "text/plain"
});//res.writeHead
res.write(data);
res.end();
});
}
If i take a normal json with functions in it give me result as object which i can instantiate to variable and use that variable as json object.but as i give function declaration in json file.it throws error.
plz guide

Answer 1

changed the json format and it worked
format is as follows:
{
"fid":{
"processDate":"function (){data=MainMasterarr;for(var i=0;i<data.length;i++){data[i]['_id'] =data[i]['_id'].substring(0,8);var mongoId = data[i]['_id'];var dateObject = new Date( mongoId );dateObject = new Date( parseInt( mongoId, 16 ) * 1000 );var date = dateObject.getDate();var month = dateObject.getMonth()+1;var year = dateObject.getFullYear().toString();var yearSub = year.substring(2,4);if(month<10)month='0'+ month;if (date<10)date='0'+ date;var dateString = month+'/'+date+'/'+yearSub;data[i]['fid'] = dateString;}}",
"consoleDate":"function (){data=MainMasterarr;console.log(data[0]['fid']);}"
},
"nloc":{
"processDate":"function (){data=MainMasterarr;for(var i=0;i<data.length;i++){data[i]['_id'] =data[i]['_id'].substring(0,8);var mongoId = data[i]['_id'];var dateObject = new Date( mongoId );dateObject = new Date( parseInt( mongoId, 16 ) * 1000 );var date = dateObject.getDate();var month = dateObject.getMonth()+1;var year = dateObject.getFullYear().toString();var yearSub = year.substring(2,4);if(month<10)month='0'+ month;if (date<10)date='0'+ date;var dateString = month+'/'+date+'/'+yearSub;data[i]['fid'] = dateString;}}",
"consoleDate":"function (){data=MainMasterarr;console.log(data[0]['fid']);}"
}
}
