Angular: Get current index in ngFor

Question

I have following angular:

    {{item}}




        
      

Answer 1

As per OP's comment on question :

So, I am trying to get the index of the ngFor in order to do a comparison to array of data before triggering another function. For example, the test() function will be triggered when I click a button, then it will check the current index, and do something with it.

You should do it like :

    // In your case this line should be within ngFor loop
    
Test Button 
    {{item}}

---

Note : Never call function like :

{{ test(i) }} // this will be executed each time anything changes in loop
