How to read key-value pairs from a list of hashmaps which is in the form of json in jquery script?

Question

Context : Json,Jquery,Java

The json object like this :

[{"7818.0":".NET Developer"},{"6124.0":".Net Off Shore Support Project Manager"},{"6125.0":".Net Off Shore Support Project Member"},{"6922.0":"2 APAC Inventory Orgs Under SPSW Manager"}]

The code in Jquery :

var roles = <%=request.getAttribute("roleList")%>
$.each(roles, function(object) {
                //display the key and value pair
                alert(object.key);
                alert(object.value);
            });

Any suggestions is really appreciated

Here json object does not have the structure with name variable. You can use index alert(object[0]); — Vishwajeet Bose, May 08 '15 at 05:19
Your life would be much easier if your JSON objects had the form `{"code":"7818.0", "name":".NET Developer"}` — Steve Chaloner, May 08 '15 at 05:28

You can change your code to :

$.each(roles, function(key,value) {
   for (var i in value) {
      alert("Key: "+i);
      alert("Value: "+value[i]);
   }                 
});

get the key and value from the map.
