angular - Angular2: Delete element from the list animation -

-

i have simple list (tasks) cards (task). when delete task, confirmation dialog called. if user confirms deletion, http call made. if it's successful variable isdeleted set true , send list item toggling class. here encounter few problems:

  1. if click on item , not delete (on confirmation choose 'no'), , click on item , delete - both of these items class (why? id's different).

    <div class="vb-task-card" [ngclass]="{'vb-deleted': task.id === selecteditemid && isdeleted}">   // here comes rest of layout    <button (click)="ondeletetask(task)"> delete</button> </div>

if user clicks on button following function called:

    public ondeletetask(task) {        this.selecteditemid = task.id;        this.deletetask.emit(task);     }
  1. how add fade out animation item delete?

p.s. if need more code or full code - let me know!

thanks in advance!

so, i've figured out. isdeleted setted on elements in *ngfor. should have property on object, this: task.deleted = true , work that.

what animations, followed official documentation.

here code:

import {component, input, output, eventemitter,     trigger,     state,     style,     transition,     animate} "@angular/core";  @component({ selector: "vb-tasks-item", animations: [     trigger('taskstate', [         state('inactive', style({opacity: 1, transform: 'translatex(0) scale(1)'})),         state('active',   style({opacity: 1, transform: 'translatex(0) scale(1)'})),         state('void',   style({opacity: 0, display: 'none', transform: 'translatex(0) scale(1)'})),         transition('* => void', [             animate('1s 8 ease-out', style({                 opacity: 0,                 transform: 'translatex(0) scale(0.5)'             }))         ])     ]) ], template: ` <div class="vb-task-card" @taskstate="task.deleted"> </div>`  export class tasksitemcomponent {    @input() public task: tasksummary;     @output() public deletetask = new eventemitter();     public ondeletetask(task) {       task.deleted = (task.deleted === 'active' ? 'inactive' : 'active');       this.deletetask.emit(task);    }  }

i'm setting animation state (task.deleted) if user confirms deletion:

public ondeletemodal(isok) {     this.ismodalopen = isok;     if(isok) {         this.taskssandbox.deletetask(this.tasktodelete.id)             .subscribe(res => {                 if (res) {                     this.tasktodelete.deleted = 'void';                     this.ismodalopen = !isok;                 }             });     }else{         this.tasktodelete.deleted = 'inactive';     } }

i use winscp download , edit .scss files , sass on linux (on server) compile them .css . after saving file, use: sass scss/style.scss css/style.css , replaces css file compiled sccs. the problem i want skip part return command line after editing scss file, sake of automation , saving time. but, if use watch command: sass --watch scss/style.scss:css/style.css synchronize 2 files, alerts nonexistent css errors pop up: change detected to: scss/style.scss error scss/style.scss (line 232: invalid css after "...ht: bold; line-": expected "{", "") note that when file uploads quicker usual (sometimes happens) watch command job, no errors. this because, when file upload takes time, sass compiles scss file (on server) before uploaded remote folder. thus, compiles part of file, resulting in css errors. is there way set timer watch command waits few seconds after detects changes , before compiling? any other way overcome is, of course, ...
