Question

Suppose I have several javascript object

{"type":"gotopage","target":"undefined"}
{"type":"press","target":"a"}
{"type":"rotate","target":"long"}

How can I add this objects to another object like

config={}

I know how to if each inserted object have a id I can added as:

config["id"]={}

But in this case how can I add objects without id?

I think you are mixing up objects and arrays. Objects have named keys, arrays have numeric keys. You can easily append to an array using .push():

var arr = [];
arr.push("something");

However, for a configuration object as your variable name suggests this is not really useful. You should rather use meaningful names for your options, e.g.:

var config = {
    something: 'blah',
    foo: 'bar'
};

You can also store an array in your object:

config.manyStuff = [];
for(...) {
    manyStuff.push(...);
}
