I am quite new to Angular 2 and I am stuck with a problem where I have to filter out all the unnecessary stuff from the JSON object I am getting from a REST API. Below is the Sample of the JSON I am receiving.
{
"refDataId":{
"rdk":1,
"refDataTypeCD":"CNTRY",
"refDataStatusCD":"C",
"effStartDT":"2017-09-01",
"effEndDT":null,
"updtUserID":"EDMO",
"updtTS":"2017-09-05"
},
"refDataDescs":[
{
"rdk":1,
"langCD":"EN_CA",
"refDataNM":"Not Applicable",
"refDataShortNM":null,
"refDataDesc":"Not issued by ISO. Dummy country code for internal reference use only.",
"updtUserID":"EDMO",
"updtTS":"2017-09-05"
}
],
"refCntry":{
"cntryRdk":1,
"cntryIso2DigitCD":"0",
"cntryIso3DigitCD":null,
"cntryIsoNumericCD":0,
"riskTypeRdk":0
}
}
{
"refDataId":{
"rdk":2,
"refDataTypeCD":"CNTRY",
"refDataStatusCD":"C",
"effStartDT":"2017-09-01",
"effEndDT":null,
"updtUserID":"EDMO",
"updtTS":"2017-09-05"
},
"refDataDescs":[
{
"rdk":2,
"langCD":"EN_CA",
"refDataNM":"Afghanistan",
"refDataShortNM":null,
"refDataDesc":null,
"updtUserID":"EDMO",
"updtTS":"2017-09-05"
}
All I need from this data is just these 2 fields : "rdk":2, "refDataNM":"Afghanistan"
I need to filter this data out and then form a new JSON Array with this data alone. Something like this :
{"id":2,"itemName":"Afghanistan"},
{"id":3,"itemName":"Albania"}
you could try something like this:
filterDate(input:any[]) {
const output=[];
input.foreach( item => output.push({"id": item.refDataId.id, "itemName": item.refDataDescs.refDataNM}));
return output;
}
