I've gotten to be fairly intermediate at consuming json objects, such
as those I'm retrieving from web api's. However, I'm trying to push
the boundaries of what I understand about JSON objects once the client
has loaded them. I have been searching around google for the last
couple of hours for what I think I want to know but I'm getting
nowhere. Hoping some other js wizzes can help me out. This isn't
directly a jQuery question, but I need to understand more about this
to help me write better jQuery code.
This is my sample data for the following questions:
var obj = { "nodes" :[
{
type : 'a',
name : 'stuff'
},
{type : 'b'},
{type : 'c'}
]
};
1) How can I add new nodes to an existing object? I can reference
obj.nodes[x].type for example. Now I want to add a new type to
"nodes". I tried: obj += {type:'d'}; but got nothing usable. Except
that obj.nodes.length went from 3 to 62.
2) Is there a list of core Javascript methods that let you work with
JSON objects? Something like .push, .pop, etc?
3) How do you search a JSON object? Suppose I want to find a group of
nodes that all have the name "stuff", regardless of what their "type"
property is?
I know I can loop through an object using for(i in obj){}.
