Customize the appearance of each element in ng-repeat individually

In my code, I have implemented an ng-repeat. Each alternate div inside the ng-repeat is supposed to have a different border-color, which is achieved by using the following structure:

<div ng-repeat="channel in channelList">
    <div ng-style="getBgColor()">
</div>

The function getBgColor() is defined as follows:

$scope.currentColorIndex = (($scope.currentColorIndex+1) % $scope.radioColors.length);
$scope.tileColor = $scope.radioColors[$scope.currentColorIndex].hex;
return $scope.tileColor;

However, I keep encountering the error:

$rootScope:infdig] 10 $digest() iterations reached

I understand that this error occurs because a different object is returned on each iteration of the ng-repeat. What could be a possible solution or workaround for this issue?

Answer №1

By utilizing the $index provided by the ng-repeat directive, you can avoid calling a separate function to access the index value within nested elements.

<div ng-repeat="channel in channelList">
    <div ng-style="{color: radioColors[$index].hex}">
</div

This code snippet dynamically assigns the color property using the hex value retrieved from the radioColors[$index].hex expression, with radioColors being a scope object.

For more details, refer to the official AngularJS documentation on ngRepeat.

Answer №2

Employing ngRepeat enables access to the $index variable.

<div ng-repeat="item in itemList">
    <div ng-style="getBgColor($index)">
</div>
