Filter array of objects on all properties value

Question

I am really surprised I haven\'t been able to find anything related to my question. I am looking for a fast way to filter my array of objects based on a user text input.

Answer 1

Well, you can use any lodash's collection related function to object and it will iterate over values. Also you can use directly _.toLower to any string or number or Boolean and it will handle all the corner cases, so if you want a easier solution, and well structured code then here you go:

data.filter(o=>_.some(o, v => _.toLower(v).indexOf('s')>-1))

Here is the working example:

let data = [{
  "id": 1,
  "first_name": "Jean",
  "last_name": "Owens",
  "email": "jowens0@google.ru",
  "gender": "Female"
}, {
  "id": 2,
  "first_name": "Marie",
  "last_name": "Morris",
  "email": "mmorris1@engadget.com",
  "gender": "Female"
}, {
  "id": 3,
  "first_name": "Larry",
  "last_name": "Wallace",
  "email": "lwallace2@example.com",
  "gender": "Male"
}];

var sTxt = 's';

var res = data.filter(o=>_.some(o, v =>_.toLower(v).indexOf(sTxt)>-1))

console.log('Result: ', JSON.stringify(res,null,'    '));

You could use Object.keys() and some() instead.

let data = [{
  "id": 1,
  "first_name": "Jean",
  "last_name": "Owens",
  "email": "jowens0@google.ru",
  "gender": "Female"
}, {
  "id": 2,
  "first_name": "Marie",
  "last_name": "Morris",
  "email": "mmorris1@engadget.com",
  "gender": "Female"
}, {
  "id": 3,
  "first_name": "Larry",
  "last_name": "Wallace",
  "email": "lwallace2@example.com",
  "gender": "Male"
}];

var result = data.filter(function(o) {
  return Object.keys(o).some(function(k) {
    return o[k].toString().toLowerCase().indexOf('s') != -1;
  })
})

console.log(result)

You could use Object.keys and omit hasOwnProperty.

This solution features arrow functions.

let data = [{ "id": 1, "first_name": "Jean", "last_name": "Owens", "email": "jowens0@google.ru", "gender": "Female" }, { "id": 2, "first_name": "Marie", "last_name": "Morris", "email": "mmorris1@engadget.com", "gender": "Female" }, { "id": 3, "first_name": "Larry", "last_name": "Wallace", "email": "lwallace2@example.com", "gender": "Male" }],
    searchText = "s",
    result = data.filter(o => 
        Object.keys(o).some(k => 
            o[k].toString().toLowerCase().indexOf(searchText) !== -1));

console.log(result);

.as-console-wrapper { max-height: 100% !important; top: 0; }

For a better performance, you could store the keys in advance and iterate the keys, without using Object.keys for all objects in the array, if they are uniform.

let data = [{ "id": 1, "first_name": "Jean", "last_name": "Owens", "email": "jowens0@google.ru", "gender": "Female" }, { "id": 2, "first_name": "Marie", "last_name": "Morris", "email": "mmorris1@engadget.com", "gender": "Female" }, { "id": 3, "first_name": "Larry", "last_name": "Wallace", "email": "lwallace2@example.com", "gender": "Male" }],
    keys = Object.keys(data[0]),
    searchText = "s",
    result = data.filter(o => 
        keys.some(k => 
            o[k].toString().toLowerCase().indexOf(searchText) !== -1));

console.log(result);

.as-console-wrapper { max-height: 100% !important; top: 0; }
