I have ng-repeat in first line of code , in the next line I need to create a dynamic variable based on what I get in ng-repeat.
code would look something like this:
<div ng-repeat="head in arrayofhead">
<span ng-if="canIbecreated_{{head}}">I am created!!</span>
</div>
where
arrayofhead = ["1","2","3"];
but this produces an error while similarly I can pass {{$index}} in this easily.
Why this ditching is present in Angularjs?
on Controller I would do
var canIbecreated_1="false";
var canIbecreated_2="true";
var canIbecreated_3="false";
To crate and not to create the span.
... ng-if="someFunc(head)" ...
Inside the ng-repeat
block. That should do the trick.
