使用相同属性值的数组将多个对象合并为单个对象

Question

I have five json objects obj1 ,obj2,obj3,obj4 and obj5, i want to merge them and crete a single json object and obj have same columns. The resultant json should have all the values from all objects
Question:

var obj1 = {
    "DOP":"manu",
    "Resolution":23,
    "sensor":"SE"
}

var obj2 = {
    "DOP":"mansa",
    "Resolution":22,
    "sensor":"PS"
}

like that all five object data and results should update only rows not as columns and expected result should be

var result = {
    "Dop":["manu","mansa"],
    "Resolution":[23,25],
    "Sensor":["SE","PS"]
}

Answer 1

You can use for(x in obj)

var result = {}
for (x in obj1) { result[x] = obj1[x] + ', ' + obj2[x] }
//Object {DOP: "manu, mansa", Resolution: "23, 22", sensor: "SE, PS"}

Answer 2

You can merge object based on passing unlimited objects as arguments in myCustomMerge() function

 function myCustomMerge() { var return_obj = {}; for (i in arguments) { obj = arguments[i]; for (j in obj) { if (return_obj[j] == undefined) { return_obj[j] = [obj[j]]; } else { return_obj[j].push(obj[j]); } } } return return_obj; } var obj1 = { "DOP": "manu", "Resolution": 23, "sensor": "SE" } var obj2 = { "DOP": "mansa", "Resolution": 22, "sensor": "PS", "special_obj2": "My Special Value" } var obj3 = { "DOP": "top", "Resolution": 36, "sensor": "ME", "special_obj2": "My Special Value 2" } var merged_obj = myCustomMerge(obj1, obj2, obj3); console.log(merged_obj);

Answer 3

The way you want result is illegal. All you can have array of your json.

 var result = [{ "DOP":"mansa", "Resolution":22, "sensor":"PS" }, { "DOP":"manu", "Resolution":23, "sensor":"SE" } ]

Answer 4

var x ={ "student-marks":{'math':1,'physics':5} }; var y ={ "student-marks":{'chemistry':3,'history':2} }; $.extend(true, {}, x, y);
