What are the best methods for troubleshooting a controller in AngularJS?

Here is the HTML code snippet I am working with:


<div class="col-md-4">{{ctrl.serviceInstance.additionalPorts}}<span
    ng-if="ctrl.serviceInstanceOfActiveDeployment != null && !ctrl.compareArrays(ctrl.serviceInstanceOfActiveDeployment.additionalPorts, ctrl.serviceInstance.additionalPorts)"
    class="glyphicon glyphicon-alert alert-icon"
    uib-tooltip-html="'Active Deployment has a different set of Additional Ports.'"></span>
</div>

This is how the controller function is defined:


function _compareArrays(arr1, arr2){
    if (arr1 === null && arr2 === null)
        return true;
    if (arr1 != null && arr2 != null) {
        arr1.sort();
        arr2.sort();
        var result = arr1.length == arr2.length && arr1.every(function(element, index) {
            return element === arr2[index];
        });
        return result;
    }
    return false;
}

I need to determine the values passed to variables arr1 and arr2. The browser is minifying the code making it difficult to access these variables directly in the console. Any suggestions on how I can tackle this issue?

Appreciate any advice!

Answer №1

For my exploration of controller scope values, I rely on ng-inspector. It offers a comprehensive tree representation that makes understanding the data much easier.

Answer №2

function _compareArrays(arr1, arr2) {
  console.log('displaying contents of arr1' + arr1);
  console.log('showing contents of arr2' + arr2);
  if (arr1 === null && arr2 === null)
    return true;
  if (arr1 != null && arr2 != null) {
    arr1.sort();
    arr2.sort();
    var result = arr1.length == arr2.length && arr1.every(function(element, index) {
      return element === arr2[index];
    });
    return result;
  }
  return false;
}
