angular7

问题 I have been working with angular for the last few weeks, and now I have a requirement to dynamically style a public site. The site admin set various color codes as well as a logo image from admin in a database. These will be reflected when the Public Site opens. As I am from an asp.net background, previously what I would do is on master page load, take values from the DB and write them into a .less file, and let java-script library take care of it.

问题 Here is a combined list, with unique ageCode. [ { "ageCode": 1, "ageDesc": "0-4", "qM": 358, "sM": 158, "qF": 328, "sF": 258 }, { "ageCode": 3, "ageDesc": "15-59", "qM": 525, "sM": 125 }, { "ageCode": 4, "ageDesc": "60+", "qF": 458, "sF": 358 } ] Combined list need to be split into individual object based on if both M & F value is present for an ageCode.

问题 I'm trying to create a custom async validator for my registration form where it checks if an email already exists. The backend returns 404 if the email does not exist and 200 if it does exist (can't change this old code). I have found a couple tutorials but didn't find one using the latest rxjs library. I created this Validation class: export class UniqueEmailValidator { static createValidator(httpClient: HttpClient, degree: number, wlId: number) { return (control: AbstractControl) => {
