Hey everyone I am trying t find the most dynamic way to loop through an array and return specific values return specific values... The json is deeply structured and may change, could there be a $.each() formula that can help?
Example:
var myobj = {
obj1: { key1: 'val1', key2: 'val2' },
obj2: { key1: '2val1',
key2: { nest1: 'val1', nest2: 'val2', nest3: 'val3' },
key3: { nest1: 'K3val1', nest2: 'K3val2',
nest3: [
{ nest1: 'val1', nest2: 'val2', nest3: 'val3' },
{ nest1: 'val1', nest2: 'val2', nest3: 'val3' }
]
}
},
obj3: { key1: 'dddddval1', key2: 'val2' }
}
now lets say i want to retrieve "K3val2
" value but instead of hardcoding it like so: myobj.obj2.key3.nest2
is there a dynamic way I do this with $.each()
mybe?
You can simply nest calls to $.each
:
Live Example | Live Source
// Loop the top level
$.each(myobj, walker);
function walker(key, value) {
// ...do what you like with `key` and `value`
if (value !== null && typeof value === "object") {
// Recurse into children
$.each(value, walker);
}
}
If you want to know how deep you are, you can do that too:
Live Example | Live Source
var path = "";
// Loop the top level
$.each(myobj, walker);
function walker(key, value) {
var savepath = path;
path = path ? (path + "." + key) : key;
// ...do what you like with `key` and `value`
if (value !== null && typeof value === "object") {
// Recurse into children
$.each(value, walker);
}
path = savepath;
}
