Angular 1: Handling Multiple Conditions and Exclusions Based on Other Conditions

I have currently added an additional span to accommodate one condition.

<div ng-repeat="(key, resultLinks) in resultGroup.resultLinks">
    <div ng-if="key < 4 || viewMore" ng-repeat="(subKey, linksWrap) in resultLinks.linksWrap">
        <span ng-if="wWidth > 568 || subKey == 0" ng-repeat="links in linksWrap.links">
                {{links.linkName}}
        </span>
    </div>
</div>

Is there a way to consolidate all the conditions into one div? For example: ng-if="(key < 4 || viewMore) || (wWidth > 568 || subKey == 0)" (something similar but not quite). Can one condition be excluded if another is true somehow?

Answer №1

Does this meet your requirements?

(key < 4 || viewMore) && (wWidth > 568 || subKey == 0)

Answer №2

Is there a way to exclude one condition if another is true?

Yes, you can achieve this using the OR (||) operator. For example, if (key < 4 || viewMore) evaluates to true, then (wWidth > 568 || subKey == 0) will not be executed.

You can simplify your code like this:

<div ng-if="(key < 4 || viewMore) || (wWidth > 568 || subKey == 0)" ng-repeat="(subKey, linksWrap) in resultLinks.linksWrap">
    <span ng-repeat="links in linksWrap.links">
            {{links.linkName}}
    </span>
</div>

However, it may look messy within the template. It's recommended to move the logic out of the template:

<div ng-if="isVisible(key, subKey)"... >

In your controller, define the isVisible function:

$scope.isVisible = function(key, subKey){  
   return (key < 4 || $scope.viewMore) || ($scope.wWidth > 568 || subKey == 0)
}
