use jQuery's find() on JSON object
jquery, jquery-selectors
Solution
jQuery doesn't work on plain object literals. You can use the below function in a similar way to search all 'id's (or any other property), regardless of its depth in the object:
function getObjects(obj, key, val) {
var objects = [];
for (var i in obj) {
if (!obj.hasOwnProperty(i)) continue;
if (typeof obj[i] == 'object') {
objects = objects.concat(getObjects(obj[i], key, val));
} else if (i == key && obj[key] == val) {
objects.push(obj);
}
}
return objects;
}
Use like so:
getObjects(TestObj, 'id', 'A'); // Returns an array of matching objects
Problem
Similar to brnwdrng's question, I'm looking for a way to search through a JSON-like object. supposing my object's structure is like so: ``` TestObj = { "Categories": [{ "Products": [{ "id": "a01", "name": "Pine", "description": "Short description of pine." }, { "id": "a02", "name": "Birch", "description": "Short description of birch." }, { "id": "a03", "name": "Poplar", "description": "Short description of poplar." }], "id": "A", "title": "Cheap", "description": "Short description of category A." }, { "Product": [{ "id": "b01", "name": "Maple", "description": "Short description of maple." }, { "id": "b02", "name": "Oak", "description": "Short description of oak." }, { "id": "b03", "name": "Bamboo", "description": "Short description of bamboo." }], "id": "B", "title": "Moderate", "description": "Short description of category B." }] }; ``` I'd like to get an object with id="A". I've tried all sort of stuff such as: ``` $(TestObj.find(":id='A'")) ``` but nothing seems to work. Can anyone think of a way of retrieving an item based on some criteria without using 'each'?
