Encountered an issue while trying to access the length property of an undefined value within an aside

I am currently utilizing ng-strap's modal, alert, and aside features. Each of them is functioning properly on their own, but when I attempt to place an alert or modal inside an aside, it throws the following error:

Uncaught TypeError: Cannot read property 'length' of undefined.

For reference, here is a plunker demonstrating the issue: http://plnkr.co/edit/vLbDAarzpbT3qk0aNw12?p=preview

I have used identical code (copied & pasted) for the modal/alert buttons both within and outside of the aside container.

<button type="button" class="btn btn-default" data-animation="am-fade-and-scale" data-placement="center" bs-modal="myModal">Modal!</button>
<button type="button" class="btn btn-default" data-placement="top" data-container="body" data-duration="3" bs-alert="errorAlert">Alert!</button>

Any suggestions on how to tackle this issue?

Answer №1

<div class="aside-body">
    <button type="button" class="btn btn-default" data-animation="am-fade-and-scale" data-placement="center" ng-click="$isShown = false" bs-modal="myModal">Open Modal!</button>
    <button type="button" class="btn btn-default" data-placement="top" data-container="body" data-duration="3" ng-click="$isShown = false" bs-alert="errorAlert">Show Alert!</button>
</div>
  • Within the ng-strap library, a scope variable $isShown is utilized to track the state of modal opening.
  • If you click "Open Modal!", it sets this variable to true. Subsequently, when clicking the "Modal" button inside the aside, it checks the variable and mistakenly toggles the wrong modal due to its status being in an opening state.
  • To address this issue without prior familiarity with the library, one workaround is manually setting $isShown to false upon clicking the "Modal" button within the aside section, as illustrated in the provided code snippet: ng-click="$isShown = false"
