I have a spinner this is shown with ng-show="loading>0"
Is there a way I can display this spinner with a delay (say 1 second)?
I can't use a timeout because with multiple requests de loading counter will get out of sync.
What I need is a delay on the ng-show
via css transition or similar
Here's a simpler approach that worked for my needs. Depending on what your action is, you would tie function setDelay()
to the element. For example, in my case I tied setDelay()
to a select input.
Trigger HTML:
<select class="first-option"
ng-change="setDelay()"
ng-options="o.label for o in download.options"
ng-model="optionModel" required>
</select>
In your controller, add a simple function setDelay
that will change the flag $scope.delay
:
$scope.setDelay = function(){
$scope.delay = true;
$timeout(function(){
$scope.delay = false;
}, 200);
};
Then, you can simply use $scope.delay
as a flag in ng-show:
<div class="loading-div" ng-show="delay">
<img src="loading_spinner.gif">
</div>
And show content after done loading:
<div ng-show="!delay">
Content is loaded.
</div>
Now, every time the user selects a new value in the dropdown menu, it will trigger$scope.delay
to be set totrue
causing the spinner to show, and when it reaches 200
, it will be set to false
causing the spinner to hide.
