Working example:

http://jsfiddle.net/0866pay3/

var json = [{"displayorder":"1","menuname":"DashBoard","menuid":"5","menuurl":"dashboard.php"},{"displayorder":"3","menuname":"Accounting Module","menuid":"3","menuurl":""},{"displayorder":"4","menuname":"My Profile","menuid":"4","menuurl":"myprofile.php"},{"displayorder":"6","menuname":"HR Module","menuid":"2","menuurl":""},{"displayorder":"9","menuname":"Administrator","menuid":"1","menuurl":""}];

    
json.forEach(function(el, idx){
    console.log(el.menuname);
});

Documentation Update

If you check out this article, you'll see the following:

callback is invoked with three arguments:

the element value

the element index

the array being traversed

So, idx is just a common way of representing the element index. You can call this whatever you'd like - theIndex, myRandomName, etc.

var myjson = [{"displayorder":"1","menuname":"DashBoard","menuid":"5","menuurl":"dashboard.php"},{"displayorder":"3","menuname":"Accounting Module","menuid":"3","menuurl":""},{"displayorder":"4","menuname":"My Profile","menuid":"4","menuurl":"myprofile.php"},{"displayorder":"6","menuname":"HR Module","menuid":"2","menuurl":""},{"displayorder":"9","menuname":"Administrator","menuid":"1","menuurl":""}]; 


var menu_names = []; 

for (var x = 0 ; x < myjson.length; x++){
    if(myjson[x].hasOwnProperty('menuname')){
        // do something usefull here 
        console.log(myjson[x]['menuname']);
        // add value to new array 
        menu_names.push(myjson[x]['menuname'])
    }
}

console.log(menu_names);
