Updating a label dynamically in Angular

QUESTION:
Is there a way to dynamically change the text of a label based on a certain condition? Specifically, I want the label to be blank when I'm on a specific route in my App.

CURRENT APPROACH:

<RadSideDrawer allowEdgeSwipe="false">
        <StackLayout tkDrawerContent class="drawer-container" VerticalOptions=LayoutOptions.FillAndExpand>
            <GridLayout rows="2*,2*,*,*,*,3*,*,*,*,*,4*" columns="*,6*">
                <Label row="0" col="0" class="fa drawerContainerSymbol" text="&#xf00d;" (tap)="onCloseDrawer()"></Label>
                <Label row="1" col="0" class="fa drawerContainerSymbol" text="&#xf053;" *ngIf="!onMonitorlist()" (tap)="onGoBack()"></Label>
                <Label row="2" col="0" class="fa drawerContainerSymbol" text=""></Label>
                ...
            </GridLayout>
        </StackLayout>
        <StackLayout tkMainContent>
            <page-router-outlet></page-router-outlet>
        </StackLayout>
    </RadSideDrawer>

The function used to check if we are on a specific route:

    onMonitorlist(){
        if(this.router.url === '/monitorliste'){
            return true;
        } else{
            return false
        }
    }

My attempt with *ngIf resulted in an unsightly white label as shown here: https://i.stack.imgur.com/d2Zi1.png

If you have a more elegant solution for dynamically displaying text on a label, please share it!

Answer №1

Customize the text displayed on your label by default. Then, when navigating to a specific route within your App, you can choose to hide that label using *ngIf along with a function you've created.

<Label *ngIf="shouldShowLabel()"> Your custom text </Label>

 shouldShowLabel(){
        if(this.router.url === '/specificroute'){
            return false;
        } else{
            return true
        }
    }

In my opinion, utilizing ngStyle based on your condition would be more suitable than using ngIf.

<Label [ngStyle]="{'display': onMonitorlist() ? 'block' : 'none'}"> your text </Label>

For my solution, I utilized the following code:

[ngClass]="{'drawerContainerTransparent': onMonitorlist()===true}"

.drawerContainerTransparent{
        background: rgb(0,204,153);
        background-color: #00CC99;
        color: rgb(0,204,153);
    }

Although the button may not physically appear disabled, I have effectively disabled its functionality by implementing logic checks. This prevents any action when attempting to interact with the seemingly invisible button.
