AngularJS is throwing a TypeError because it cannot access the '0' property of an undefined value

    for ( var i = 0; i < members.length; i++ ) {

        var value = value[i];
        console.log(value);

    }

Feeling really bewildered by how this could be incorrect...

'i' is set to zero, so it's perplexing how the value couldn't be found.

Here is all of my controller code:

 angular.module(module.name).controller(module.name + '.c.' + current.name, [
        '$scope',
        '$stateParams',
        'members',
        'assessment', 
        '$localStorage',  

    function (scope, stateParams, members, assessment, $localStorage) {
        scope.members = members;        
        // Assessment and item scope variables
        scope.assessment = assessment;             

        scope.active = $localStorage.$default({
            value : false
        });  

        console.log(members.length);      

        // Currently, this function only logs messages
        scope.change = function (active) {

            if (active) {
                scope.active = $localStorage.$default({
                    value : true
                });
                console.log('hi 1');
            } else {
                scope.active = $localStorage.$default({
                    value : false
                });
                console.log('hi 2');
            }
        };   

        for ( var i = 0; i < members.length; i++ ) {

            var value = value[i];
            console.log(value);
        }
    }
]);

UPDATE

This is what I was aiming for:

for ( var i = 0; i < members.length; i++ ) {

        value = "value" + i;

        console.log(value);
}          

Answer №1

From what I can gather, the value should be either true or false. Therefore, you should consider removing the line:

value = value[i];

It seems like you intend to work with the array of values in the members variable. In that case, please update your code to:

value = members[i];

Answer №2

After reviewing your previous feedback, you may prefer the following approach:

for ( var i = 0; i < members.length; i++ ) {
        console.log('value' + i);
}

This will result in the output:

value0

value1

value2

.....

If you wish to display member values, you can use the following code snippet:

for ( var i = 0; i < members.length; i++ ) {
     console.log(members[i]);
}
