Looking for a way to change a variable in a group of child components, I have this component for an editable form control that toggles between view states
import {
Component,
Input,
ElementRef,
ViewChild,
Renderer,
forwardRef,
OnInit
} from '@angular/core';
import { ControlValueAccessor, NG_VALUE_ACCESSOR } from '@angular/forms';
const INLINE_EDIT_CONTROL_VALUE_ACCESSOR = {
provide: NG_VALUE_ACCESSOR,
useExisting: forwardRef(() => InlineEditComponent),
multi: true
};
@Component({
selector: 'inline-edit',
templateUrl: 'inline-edit.html',
providers: [INLINE_EDIT_CONTROL_VALUE_ACCESSOR],
})
export class InlineEditComponent implements ControlValueAccessor, OnInit {
@ViewChild('inlineEditControl') inlineEditControl: ElementRef;
@Input() label: string = '';
@Input() type: string = 'text';
@Input() required: boolean = false;
@Input() disabled: boolean = false;
private _value: string = '';
private preValue: string = '';
public editing: boolean = false;
public onChange: any = Function.prototype;
public onTouched: any = Function.prototype;
get value(): any {
return this._value;
}
set value(v: any) {
if (v !== this._value) {
this._value = v;
this.onChange(v);
}
}
writeValue(value: any) {
this._value = value;
}
public registerOnChange(fn: (_: any) => {}): void {
this.onChange = fn;
}
public registerOnTouched(fn: () => {}): void {
this.onTouched = fn;
}
constructor(element: ElementRef, private _renderer: Renderer) {
}
ngOnInit() {
}
}
<div>
<div [hidden]="!editing">
<input #inlineEditControl [required]="required" [name]="value" [(ngModel)]="value" [type]="type" [placeholder]="label" />
</div>
<div [hidden]="editing">
<label class="block bold">{{label}}</label>
<div tabindex="0" class="inline-edit">{{value}} </div>
</div>
</div>
Trying to come up with a directive to utilize these components and switch the editing flag to true
export class EditForm {
//Thinking of doing something like this:
public toggleEdit(fn: () => {}): void {
var editableFormControls = $('#selector: 'inline-edit');
editableFormControls.forEach(control => control.editing = true)
}
}
Interested in finding a way to select all the editable form controls and set the editing flag to true in each of them. Any suggestions?
