Angular = encountering an incorrect array size limitation

I am encountering an issue with the function in my controller...

$scope.pagerPages = function (n) {
    var i = Math.ceil(n);
    return new Array(i);
}

The n value is derived from an expression on the view and can sometimes be a fraction. This is why I have used Math.ceil on n.

Does anyone have insight into why this error is occurring?

Invalid array length

EDIT: n is calculated from the view

<div ng-repeat="i in pagerPages( report.TotalNumRows / report.View.PageSize ) track by $index">
...
</div>

The calculation results in 11.2, which seems to be functioning correctly since I get 12 iterations of the div element on the page. Yet, the error persists. Any suggestions?

Answer №1

Make sure to check the value assigned to i. It might be negative.

Even if n was a string or an object, the code would still function correctly. The only scenario where you would encounter an error is if i is a negative number.

For example, new Array({}) or new Array('ergerg') will not cause an error, but new Array(-2) will trigger the error you are experiencing.
