이 같은 JSON 문자열을 자바 스크립트

Question

변수로 JSON 요소를 추출하는 방법 :

var jsondata = document.getElementById("jsonArray").value; 

은 어떻게 추출합니까 : 나는 JS 파일에 다른 파일에서 얻고있다

이런 변수 jsondata에서 JSON 요소 : 등

RefData.COMPLIANCE_ID = [ 
     "1/FIRST/US/191CC2/20160906/pW1WSpD/1", "1/FIRST/US/191CC2/20160906/pW1PUxP/1" 
    ]; 

..

Answer 1

내가이 일을 생각하십시오. 이 시점 refdata로에서

var jsondata = document.getElementById("jsonArray").value; 
var json = JSON.parse(jsondata); 

json.map(function(obj) { 
    var keys = Object.keys(obj); 
    keys.forEach(function(key) { 
    if (!RefData[key]) { 
     RefData[key] = []; 
    } 
    RefData[key].push(obj[key]); 
    }); 
}); 

2 개 값을 모두 배열 인 등 COMPLIANCE_ID, 관용, WEIGHTED_ARR_LAST_SLP ... 같은 특성을 가져야한다.

Answer 2

이

var json = JSON.parse(jsondata); 

var compliance_id = json["COMPLIANCE_ID"];
