Question

I have the following JSON:

var json = {
“system” : {
“world” : {
“actions” : {
“hello” : {
“src” : “hello world/hello world.js”,
“command” : “helloWorld”
}
}
}
}
}

I have the following javascript:

var x = “system”;
// get the contents of system by doing something like json.getElementByName(x)

How do I get the contents of system using json and x in jQuery?

Answer 1

Just use:

var x = "system";
json[x];

It is a key/value system of retrieval, and doesn’t need a function call to use it.
