You can make use of differenceWith() with an isEqual() comparator, and invoke isEmpty to check if they are equal or not. var isArrayEqual = function(x, y) { return _(x).differenceWith(y, _.isEqual).isEmpty(); }; var result1 = isArrayEqual( [{a:1, b:2}, {c:3, d:4}], [{b:2, a:1}, {d:4, c:3}] ); var result2 = isArrayEqual( [{a:1, b:2, c: 1}, {c:3, d:4}], [{b:2, … Read more
You should be able to do it fairly simply with recursion. The way it works, is you just recursively call a parser on object children that prepend the correct key along the way down. For example (not tested very hard though): const source = { a: 1, b: { c: true, d: { e: ‘foo’ … Read more
Just use recursion to walk the object. var person = { name: “somename”, personal: { weight: “150”, color: “dark”, foo: { bar: ‘bar’, baz: ‘baz’ }, empty: { } } }; // however you want to do this var isobject = function(x){ return Object.prototype.toString.call(x) === ‘[object Object]’; }; var getkeys = function(obj, prefix){ var keys … Read more
You could use reduce like this: const keyify = (obj, prefix = ”) => Object.keys(obj).reduce((res, el) => { if( Array.isArray(obj[el]) ) { return res; } else if( typeof obj[el] === ‘object’ && obj[el] !== null ) { return […res, …keyify(obj[el], prefix + el + ‘.’)]; } return […res, prefix + el]; }, []); const input … Read more
Here’s a non-jQuery version: function toQueryString(obj) { var parts = []; for (var i in obj) { if (obj.hasOwnProperty(i)) { parts.push(encodeURIComponent(i) + “=” + encodeURIComponent(obj[i])); } } return parts.join(“&”); }
That is not an array that is an object. You’d be better creating a property of the object that is an array and store the different values in there. var myarray = { “field_1”: “lorem ipsum”, “field_array”: [] }; myarray.field_array.push(value); then just loop through that property of the array.
if it’s always the first property of message.name, you could do something like: var keys = []; for (var l in message.name) { if (message.name.hasOwnProperty(l)){ keys.push(l); } } //=>first property value should now be in message.name[keys[0]]); // (its label is keys[0]) Edit: nine years after this answer all modern browsers support es20xx, so it’s safe … Read more
You can use map and Object.values let array = json.map(obj => Object.values(obj));
Explanation So first, your two lines of code create a function, obj, and assign to it’s prototype {x: 5}. When you create an instance of this object, it seems to have an internal reference to the prototype that existed when it was new‘d. After this, you reassign the prototype to {y: 6} which does not … Read more
A simple recursive implementation: _.mixin({ /* * @mixin * * Splits a collection into sets, grouped by the result of running each value * through iteratee. If iteratee is a string instead of a function, groups by * the property named by iteratee on each of the values. * * @param {array|object} list – The … Read more
