Example 1: ngfor index
<ul> <li *ngFor="let item of items; let i = index" [attr.data-index]="i"> {{item}} </li> </ul>
Example 2: ngfor get index
<ul> <li *ngFor="let item of items; let i = index" [attr.data-index]="i"> {{item}} </li> </ul>
Example 3: ngfor index
/* ngFor with index in angular is used here for generating 'li' element till the studentDetails array length. And also make a note if you are using angular 1 then you have to replace 'let' with '#', but its ok if you are using angular 2 or above. */ <ul> <li *ngFor="let student of studentDetails; index as i;" [attr.data-index]="i"> {{student}} </li> </ul> /* I hope it will help you. Namaste */
