eg: When the corresponding value of the passed-in ID is true, add a class named focus to the corresponding ID tag, such as:

var obj = { id01:'true', id02:'flase', id03:'true'};

$.each(obj,function(key,val){ 
   if(val == 'true'){ 
      $('#' + key).addClass('focus'); 
    } 
});

Copy after login

Result: A class tag will be added to the tags with IDs id01 and id03;

eg2:

The json data is as follows:

[ 
{"Id": 10004, "PageName": "club"}, 
{"Id": 10040, "PageName": "qaz"}, 
{"Id": 10059, "PageName": "beauty"}
]

Copy after login

If you want to use jquery to operate on this data, use $.each:

$.each(data, function(i, item) {
  alert(item.PageName);
});

Copy after login

I personally tested it and it works.
