Angular ng-if="" with multiple arguments

I am trying to get started on angular development. And after reviewing the documentation some questions persist. How do i best write a ng-if with multiple arguments corresponding to

if( a && b) or if( a || b )

Solution 1:

It is possible.

<span ng-if="checked && checked2">
  I'm removed when the checkbox is unchecked.
</span>

Solution 2:

Just to clarify, be aware bracket placement is important!

These can be added to any HTML tags... span, div, table, p, tr, td etc.

AngularJS

ng-if="check1 && !check2" -- AND NOT
ng-if="check1 || check2" -- OR
ng-if="(check1 || check2) && check3" -- AND/OR - Make sure to use brackets

Angular2+

*ngIf="check1 && !check2" -- AND NOT
*ngIf="check1 || check2" -- OR
*ngIf="(check1 || check2) && check3" -- AND/OR - Make sure to use brackets

It's best practice not to do calculations directly within ngIfs, so assign the variables within your component, and do any logic there.

boolean check1 = Your conditional check here...
...

Solution 3:

For people looking to do if statements with multiple 'or' values.

<div ng-if="::(a || b || c || d || e || f)"><div>

Solution 4:

Yes, it's possible. for example checkout:

<div class="singleMatch" ng-if="match.date | date:'ddMMyyyy' === main.date &&  match.team1.code === main.team1code && match.team2.code === main.team2code">
    //Do something here
    </div>
