我有一系列字典var nodes ={A: {'name' : 'A'},B:{'name' : 'B'},C:{'name' : 'C'},D:{'name' : 'D'}E:{'name' : 'E'}}和另一個(gè)數(shù)組var X_Group = ['A', 'B'];我需要遍歷每個(gè)字典元素，如果它存在于數(shù)組 X_Group 中，則將值 X 附加到它們，否則附加 Y。IE。var nodes ={A: {'name' : 'A' , group :'X'},B:{'name' : 'B', group :'X'},C:{'name' : 'C', group :'Y'},D:{'name' : 'D', group :'Y'},E:{'name' : 'E', group :'Y'}}我努力了： for (var key in nodes){ if (key in X_Group) nodes[key].group = 'X';else nodes[key].group = 'Y'; }But it does not work. Any suggestions on how to fix the issue?
根據(jù)條件javascript將鍵值對附加到字典數(shù)組
