You mention you have a string. Use JSON.parse for that. Also, make sure it is an array. Afterwards, you can manually iterate through each object in the array and push the value
var str = '[{"name": "Joene Floresca"},{ "name": "Argel "}]';
var objA = JSON.parse(str);
var values = [];
for (var i = 0; i < objA.length; i++) {
for (var key in objA[i]) {
values.push(objA[i][key]);
}
}
console.log(values);

Assuming your JSON is an array, you can use map:
// Your JSON string variable
var jsonString = '[{"name":"Joene Floresca"},{"name":"Argel "}]';
// Parse the JSON to a JS Object
var jsObject = $.parseJSON(jsonString);
// Use map to iterate the array
var arr = $.map(jsObject, function(element) {
// Return the name element from each object
return element.name;
});
console.log(arr); // Prints ["Joene Floresca", "Argel "]<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>

You can iterate over objects inside array and store the names in a second array.
var data = JSON.parse('[{"name":"Joene Floresca"},{"name":"Argel "}]');
var names = [];
data.forEach(function(model) {
names.push(model.name);
});
// names now contains ["Joene Floresca", "Argel"]
alert(names);
[]around it to make it an array.[{"name":"Joene Floresca"},{"name":"Argel "}]this is the correct way right?- @RGrahamvar jsonstring = '[{"name":"Joene Floresca"},{"name":"Argel "}]';is json string.
