Using each in jQuery to process json data, jqueryjson

Eg: when the value of the passed ID is true, add a class named focus to the ID label, for example:

Var obj = {id01: 'true', id02: 'flase ', id03: 'true'}; $. each (obj, function (key, val) {if (val = 'true') {$ ('#' + key ). addClass ('focal ');}});

Result: A class label is added for the ID id01 and id03 labels;

Eg2:

Json data is as follows:

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

To use jquery to operate the data, use $. each:

$. Each (data, function (I, item) {alert (item. PageName );});

It is feasible for me to perform the test.
