Verifying child attributes within a collection using AngularJS expressions

Is there a way to write an angular expression that can check each child item in a list and return true if any child has a specific property value?

My issue involves a chart legend generated by an ng-repeat expression. I want the wrapping element to be shown only if any of the child items in the list has the property "datavisible" set to true.

Currently, I have a $scope variable called "anydatavisible" that is set to true if any of the data series is activated, which I then use in an expression.

<div class="chart-legend" ng-show="anydatavisible">
    <div ng-repeat="item in model.Accounts track by item.Id" ng-if="item.datavisible">
        {{item.Name}}
    </div>
</div>

I am curious if I can achieve the same result by utilizing an expression that checks each child, eliminating the need for the variable "$scope.anydatavisible".

I'm envisioning something like this:

<div class="chart-legend" ng-show="any(model.Accounts).datavisible">
    <div ng-repeat="item in model.Accounts track by item.Id" ng-if="item.datavisible">
        {{item.Name}}
    </div>
</div>

Answer №1

Give this a shot:

<div class="legend-graph" ng-display="(model.Users | sort:{visible:true}).length > 0">
