For my application, I am using two different languages and have written them within two <option> tags. Is it possible to combine both conditions into a single <option> tag using interpolation?
<option *ngIf="this.language=='en' || category.odiyaName==null" [value]="category.id">
{{category.name}}
</option>
<option *ngIf="this.language=='or' && category.odiyaName" [value]="category.id">
{{category.odiyaName}}
</option>
Interpolation can also utilize conditions. Notice the use of parentheses around the condition and how it is not necessary to explicitly reference the current language in this context. I have also incorporated the "safe" operator to ensure that if odiyaName is null or undefined, the ternary operation will still function correctly.
<option [value]="category.id">
{{(language=='en' || !category?.odiyaName)
?category.name
:category.odiyaName}}
</option>
To display the option, you can utilize an if else block.
<option [value]="category.id">
<ng-container *ngIf="this.language=='en' || category.odiyaName==null; else elseBlock">
{{category.name}}
</ng-container>
<ng-template #elseBlock>
<ng-container *ngIf="this.language=='or' && category.odiyaName">
{{category.odiyaName}}
</ng-container>
</ng-template>
</option>
Implement your custom logic in a component and then pass it to the template for streamlined HTML.
<option [value]="category.id"> {{displayCategoryName(category)}} </option>
Component(.ts) file:
displayCategoryName(category){
if(this.language==='en' || !category.odiyaName){
return category.name
}else if(this.language=='or' && category.odiyaName){
return category.odiyaName;
}
}
