I know you bored from this bug, So we are here to help you! Take a deep breath and look at the explanation of your problem. We have many solutions to this problem, But we recommend you to use the first method because it is tested & true method that will 100% work for you.
Method 1
Add to your scope:
$scope.isNumber = angular.isNumber;
and then use:
ng-show="isNumber(10)"
Method 2
<div ng-controller="Ctrl" ng-show="isNumber(num)">
AAA
</div>
function Ctrl($scope){
$scope.num = '10';
$scope.isNumber= function (n) {
return !isNaN(parseFloat(n)) && isFinite(n);
}
}
Here’s a JS Fiddle http://jsfiddle.net/7RD47/
It uses the top answer from Validate decimal numbers in JavaScript – IsNumeric(), which is a more complete way of validating numbers.
Method 3
Try this:
ng-show='isNumeric(10)'
Note: Use and implement method 1 because this method fully tested our system.
