parse json object in javascript to get key and values
16,811
Solution 1
JSON.parse is use to parse JSONString to Javascript Object.
You can not use it directly on a JavaScript Object ...
Anyway, your object is an array so you may do :
var arr = JSON.parse(data);
arr.forEach(function(elementObject){
var keys = Object.keys(elementObject);
keys.forEach(function(key){
console.log(key + ":"+elementObject[key]);
})
});
Cheers
Solution 2
Here you will get the values in array "values".
var data= [{"obj1":"2122"},{"obj2":"123"}]
data = JSON.stringify(data);
var values = [];
JSON.parse(data, function (key, value) {
if (typeof(value) != "object") {
values.push({[key]:value});
// values.push(value); //if you need a value array
}
});

I have a object, need to parse the below data
var data= [{"obj1":"2122"},{"obj2":"123"}]
to get both the keys and values in javascript. I yried to use:
var obj = JSON.parse(data); for(var prop in data) { if(data.hasOwnProperty(prop)) console.log(prop); }
The values that are obtained in console are
Object {obj1: "2122"} Object {obj2: "123"}
But I need to access the values seperately and not as object. How to retrieve it from that object?

T J about 8 years"String to JSON" - no, it's for converting a JSON string (A string that adhere's to JavaScript Object Notation) to JavaScript object. JavaScript Object != JSON
