Encountering the error "Unable to assign value to 'items' property of an undefined object" when attempting to include a child object within a JavaScript object

While attempting to append an array onto an object, I encountered the error message "Cannot set property 'items' of undefined." My goal is outlined below:

$rootScope.jobs.items = [];
$rootScope.jobs.item = {};
$rootScope.jobs.after = 0;
$rootScope.jobs.noOfRecord = 10;
$rootScope.jobs.busy = false;
$rootScope.jobs.finish = false;

In this context, $rootScope represents a valid object that is AngularJS-compatible and designed for adding objects. There are no reported issues with $rootScope.

I have reviewed responses on Why I get Cannot set property 'na0' of undefined error?, but concluded that my scenario differs.

Answer №1

Before proceeding, make sure to initialize the $rootScope.jobs variable with the necessary properties.

$rootScope.jobs = { 
    items : [],
    item: {}, 
    after: 0,
    noOfRecord: 10,
    busy: false,
    finish:false
};

Answer №2

In order to properly set up your code, it is important to explicitly define the variable jobs. An example of how this can be done is shown below:

$rootScope.jobs = {} ;

Answer №3

The error message is clear - $rootScope.jobs has not been defined.

When you attempt to add the property items to an undefined object, this issue arises.

To address this problem, simply initialize the jobs property on the $rootScope:

$rootScope.jobs = {};
