lodash - 必要值檢查

Posted at 2016-04-13 lodash

lodash 是一個值得好好細細品嘗的模組，內含許多擴充的function去針對物件、字串、陣列處理。

必要值檢查

var should = require('chai').should();
var _ = require('lodash');

describe('require keys', function () {
  it('case 1:', function (done) {
    var requiredKeys = ['firstname', 'lastname', 'email'],
    params = {
      "firstname": "ailin",
      "lastname": "liou",
      "email": "NONE"
    };
    var result = _.every(requiredKeys, _.partial(_.has, params));
    result.should.be.equal(true);
    done();
  });

  it('case 2:', function (done) {
    var requiredKeys = ['firstname', 'lastname', 'email', 'phone'],
    params = {
      "firstname": "ailin",
      "lastname": "liou",
      "email": "NONE"
    };
    var result = _.every(requiredKeys, _.partial(_.has, params));
    result.should.be.equal(false);
    done();
  });

  it('case 3:', function (done) {
    var requiredKeys = ['firstname', 'email'],
    params = {
      "firstname": "ailin",
      "lastname": "liou",
      "email": "NONE"
    };
    var result = _.every(requiredKeys, _.partial(_.has, params));
    result.should.be.equal(true);
    done();
  });
});
