2 JSON（オブジェクトの配列）JSONの

Question

例の構造比較：

{ "array_name1" : [ 
     {"name":"John","age":"18","group":"user","country":"UK","hobby":"series","sport":"football"}, 
{"name":"Ted","age":"20","group":"user","country":"US"}, ...]} 

{ "array_name2" : [ 
     {"name":"John","age":"18","group":"admin","country":"UK","hobby":"series","sport":"football"}, 
{"name":"Ted","age":"20","group":"user","country":"US", sport:"tennis"}, 
{"name":"David","age":"20","group":"user", sport:"tennis"},...]} 

{ "array_name3" : [ 
     {"name":"John","age":"18","group":"admin","country":"UK","hobby":"series","sport":"football"}, 
{"name":"David","age":"20","group":"user", sport:"tennis"},...]} 

をIは、オブジェクトの2 JSON配列を比較しなければなりません。 オブジェクトの2つの異なる配列内の同じ名前のオブジェクトを比較する必要があります。 たとえば、array_name1とarray_name2を比較する必要があります。新しいオブジェクトがarray_name2に含まれていることを検出する必要があります。また私は、Johnからgroupへの値がユーザーから管理者に変更されたことを検出する必要があります。 array_name2とarray_name3を比較する必要がある場合は、ユーザーTedがarray_name3で削除されたことを検出する必要があります。

Answer 1

は

var com = { "array_name1" : [ 
 
     {"name":"John","age":"18","group":"user","country":"UK","hobby":"series","sport":"football"}, 
 
{"name":"Ted","age":"20","group":"user","country":"US"}]}; 
 

 
var com1 = { "array_name2" : [ 
 
     {"name":"John","age":"18","group":"admin","country":"UK","hobby":"series","sport":"football"}, 
 
{"name":"Ted","age":"20","group":"user","country":"US", "sport":"tennis"}, 
 
{"name":"David","age":"20","group":"user", "sport":"tennis"}]} 
 

 
var com2 = { "array_name3" : [ 
 
     {"name":"John","age":"18","group":"admin","country":"UK","hobby":"series","sport":"football"}, 
 
{"name":"David","age":"20","group":"user", "sport":"tennis"}]}; 
 
var com3 = { "array_name3" : [ 
 
     {"name":"John","age":"18","group":"admin","country":"UK","hobby":"series","sport":"football"}, 
 
{"name":"David","age":"20","group":"user", "sport":"tennis"}]}; 
 
console.log(com.array_name1 === com1.array_name2); // direct compare 
 

 
function checkEqual(x,y) { 
 
    return JSON.stringify(x) === JSON.stringify(y); 
 
} 
 
console.log(checkEqual(com.array_name1, com1.array_name2)); 
 

 
console.log(checkEqual(com3.array_name3, com2.array_name3));
