When loading a URL, I want to display an error message immediately if the URL is invalid.
Currently, I have set an interval of 1 second on the function that checks the validity of the URL. However, the error message only appears when I click on an empty area of the screen.
How can I ensure that the error message is displayed as soon as the URL loads?
This is the code I am using:
timer = setInterval(function() {
$scope.ValidateUrl();
}, 1000);
It seems necessary to instruct Angular to monitor changes in the scope. When using a native JS method within an AngularJS application, Angular may not automatically track the modifications made by it.
To ensure that Angular keeps track of changes in the current scope, you can use $apply(fn):
$scope.$apply(function(){
return $scope.ValidateUrl();
});
It appears that the digest cycle is not running due to your usage of the JavaScript function setInterval. It is recommended to use $interval instead. Wrapping the function in $interval will ensure that the digest cycle runs after the function execution.
Modified Code
timer = $interval(function() {
$scope.ValidateUrl();
}, 1000);
