how to loop through json array in jquery?

Question

I have a php page from which I get response in json:

[{\'com\':\'something\'},{\'com\':\'some other thing\'}]

I want to loop it and append

Answer 1

var data = [ 
 {"Id": 10004, "PageName": "club"}, 
 {"Id": 10040, "PageName": "qaz"}, 
 {"Id": 10059, "PageName": "jjjjjjj"}
];

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

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

Or else You can try this method

var data = jQuery.parseJSON(response);
$.each(data, function(key,value) {
   alert(value.Id);    //It will shows the Id values
});
