I'm working on an application where I need to highlight rows based on a count value using ngFor in Angular.
After trying different approaches, I was only able to highlight the specific row based on my count. Can someone please assist me?
If my count value is 3, I want to highlight rows with indexes 0, 1, and 2.
Modify the line
[ngClass]="(count-1==i)?'newMsg':'oldMsg'"[ngClass]="(count-1>=i)?'newMsg':'oldMsg'"In addition, you have the option to send a function as shown below:
[ngClass]="isMessageNew(i)?'newNotification':'oldNotification'"
Within the component file:
isMessageNew(idx) {
if (idx < this.messageCount) {
return true;
}
return false;
}
