Tips on deactivating a div when a checkbox is selected

I am currently working with a checkbox element in my code:

<md-checkbox checked.bind="addEventCommand.allDay" change.delegate="allday()">All Day</md-checkbox>

When the above checkbox is true, I want to disable the following div:

<div class="row" >
<md-input label="Start DateTime" value.bind="addEventCommand.startTime" ></md-input> 
<md-input label="End DateTime" value.bind="addEventCommand.endTime"></md-input>
</div>

Typically, in JavaScript, I would simply get the element and disable it. However, in Angular Materialize and TypeScript, I am unsure of how to accomplish this.

In my TypeScript file, I have added the following function:

allday() {
        if (this.addEventCommand.allDay === true) {
            
        }
        
    }

I attempted to use a reference on the checkbox like so:

 <md-checkbox  ref="addEventCommand.allDay.check"checked.bind="addEventCommand.allDay" >All Day</md-checkbox>

And on the targeted div, I tried the following disabled binding:

<div class="row" disabled.bind="addEventCommand.allDay.check.checked"></div>

Unfortunately, these attempts did not produce the desired effect.

Answer №1

Implement an ngModel directive on the checkbox element, then use ngIf to toggle its visibility

<div *ngIf="toShow">
My content
</div>

<input type="checkbox" [(ngModel)]="toShow">

ts

toShow = true;

Answer №2

Elements such as checkboxes and text inputs have a disabled property which makes them unresponsive. However, div elements do not possess this property.

An effective solution is to create a CSS class named 'disabled' with the following styling:

.disabled {
  background: gray;
  pointer-events: none;
}

To implement this in your HTML code:

<div class="box" [class.disabled]="task.completed.checkbox.checked"></div>
