How to break out of a loop with a ng-if statement in AngularJS

I am struggling with the following code snippet: $scope.counter = '1';

<div ng-repeat="cat in catadata">
   <div ng-if="cat.TopCategoryID = 2" >
      <div ng-if="counter = 1" >
         <div class="feedsDisplay" ng-init="counter = counter + 1">
            Creater Img:{{cat.CreatedBy_Profile.Picture.URI}}" 
         </div>
      </div>
   </div>
</div>

My goal is to halt the loop when counter = 2, and only display a single result.

ng-init="counter = counter + 1
{{counter}}

Instead of displaying 11111 as it currently does, I need it to show 12345

Answer №1

make sure to use == for comparison instead of =

Give this a try:

ng-if="counter == 1"

remember that the value of counter is a string. Use the + sign before incrementing.

update your code like so:

ng-init="counter = +counter + 1"

It is not possible to selectively stop the ng-repeat feature. However, if you only want to display one result, you can use the following code:

<div ng-repeat="item in items | limitTo : 1">

OR

<div>{{items[0]}}</div>

Instead of improperly using ng-repeat, ng-init, and ng-if in this way, consider extracting the first matching cat before displaying it, for example in a controller, directive, or service:

for (var i = 0, maxI = catadata.length; i < maxI; ++i) {
    if (cat.TopCategoryID === 2) {
        $scope.firstMatchingCat = cat;
        break;
    }
}

Afterwards, in the template:

<div class="feedsDisplay">
    Creator Image:{{firstMatchingCat.CreatedBy_Profile.Picture.URI}}"
</div>
