I have an object in JSON format as shown below, and I am looking to extract values from the array without needing to specify a key
const myData = {
"VALUEX": "GrandTotal",
"VALUEX2": "GrandTotal",
"Jan-2018": 25,
"Feb-2018": 54.5,
"Mar-2018": 84,
"Apr-2018": 45.2,
"May-2018": 46,
"Jun-2018": 76.5,
"Jul-2018": 107,
"Aug-2018": 138,
"Sep-2018": 168.5,
"Oct-2018": 199,
"Nov-2018": 229.5,
"Dec-2018": 260
}
If you need to retrieve the value of an object without knowing the specific key, there are a few methods you can use:
Method 1: Utilizing Object.values()
var myData = {"VALUEX":"GrandTotal","VALUEX2":"GrandTotal","Jan-2018":25,"Feb-2018":54.5,"Mar-2018":84,"Apr-2018":45.2,"May-2018":46,"Jun-2018":76.5,"Jul-2018":107,"Aug-2018":138,"Sep-2018":168.5,"Oct-2018":199,"Nov-2018":229.5,"Dec-2018":260}
console.log(Object.values(myData));Method 2: Using Object.entries()
var myData = {"VALUEX":"GrandTotal","VALUEX2":"GrandTotal","Jan-2018":25,"Feb-2018":54.5,"Mar-2018":84,"Apr-2018":45.2,"May-2018":46,"Jun-2018":76.5,"Jul-2018":107,"Aug-2018":138,"Sep-2018":168.5,"Oct-2018":199,"Nov-2018":229.5,"Dec-2018":260}
var arrayVal = Object.entries(myData).map(item => item[1]);
console.log(arrayVal);Method 3: Employing Object.keys()
var myData = {"VALUEX":"GrandTotal","VALUEX2":"GrandTotal","Jan-2018":25,"Feb-2018":54.5,"Mar-2018":84,"Apr-2018":45.2,"May-2018":46,"Jun-2018":76.5,"Jul-2018":107,"Aug-2018":138,"Sep-2018":168.5,"Oct-2018":199,"Nov-2018":229.5,"Dec-2018":260}
var arrayVal = [];
Object.keys(myData).forEach(key => arrayVal.push(myData[key]));
console.log(arrayVal);Simply employ the notation below:
myData["VALUEX"]
This will be interpreted as "GrantTotal".
To loop through the keys and values, use the code snippet:
for(var key in myData){
if(myData.hasOwnProperty(key){
console.log(myData[key]);
}
}
