javascript - FadeIn Animation to Validations- Angular -


i want add fade-in transition validation labels in angular-

   <form [formgroup]="regform">       <div formgroupname="teamdetails">         <div class="form-group">           <label for="teamname">team name:</label>           <label class="validations" *ngif="!regform.get('teamdetails.teamname').valid && regform.get('teamdetails.teamname').touched">please enter valid team name!</label>           <input type="text" class="form-control" formcontrolname="teamname" id="teamname" required placeholder="enter team name">         </div>

i want them appear opacity transition, tried $('label').fadein(2000); in jquery didn't work.

add animation component decorator:

animations:[ trigger('load', [         transition(':enter', [             style({ opacity: 0 }),             animate(600, style({ opacity: 1 }))         ]),         transition(':leave', [             style({ opacity: 1 }),             animate(600, style({ opacity: 0 }))         ])      ])   ]

andand in view :

  <label @load style="color:red" *ngif="mymodel.invalid">invalid</label>

don't forget add module:

import { browseranimationsmodule } '@angular/platform-browser/animations';

....

  imports:      [ ...., browseranimationsmodule ],

(side note: core of problem entanglement of user input firing “expensive computations”. therefore, cannot separate both in 2 scripts, , letting 1 spawning other daemon.) the command screen may you. use screen -l create new session , run application. after inputting data, can press " ctrl-a " , press " d " on keyboard detach session. now
