Inline in AngularJs is there a way to check if something is an array? I would have thought this to work: <div ng-show="Array.isArray(textStuff[0][1])">Hi</div> I have verified it is in fact an array. Is there something I am missing or another way? You can put angular.isArray on the scope... $scope.isArray = angular.isArray; <div ng-show="isArray(textStuff[0][1])">Hi</div> Fiddle You can create global filters to use in your JS or HTML to check against object types.

阅读更多关于 ng-show=“true” but still has class=“ng-hide”

I'm new to AngularJS, so there may be a simple resolution to my problem. I've been working on this form. I have two inputs - one is for the number of doors and one is for the number of windows.

But the element still has the class of "ng-hide" on it which still leaves it hidden. Here's a sample of my code: <body ng-app> Doors: <input type="number" ng-model="doors"><br> Windows: <input type="number" ng-model="windows"><br>

阅读更多关于 AngularJS filter based on array of strings?

I'm having a hard time wrapping my head around how to go about doing an Angular filter to solve a problem that I'm running into.

For the sake of example let's say I am outputting each of those objects as a row in a table.
