Answer 1

 function addValueInObject(value, object, key) {

        var addMoreOptions = eval('{"'  + key + '":' +  value + '}');

        if(addMoreOptions != null) {
            var textObject = JSON.stringify(object);
            textObject = textObject.substring(1,textObject.length-1);
            var AddElement = JSON.stringify(addMoreOptions);
            object = eval('{' + textObject +','+  AddElement.substring(1,AddElement.length-1) + '}');
        }
        return object;
    }

addValueInObject('sdfasfas', yourObject, 'keyname');

OR:

var obj = {'key':'value'};

obj.key2 = 'value2';
