The problem I have - the content of an HTTP canvas disappears, when I have a tooltip on a button that opens a new tab.
This is a very specific symptom, so I'd try to walk you through it.
I'm able to reproduce it with the following HTML, but not in a plunker or jsfiddle unfortunately:
<html>
<head>
<style>
.container {
height: 300px;
width: 300px;
}
canvas {
border: 1px solid black
}
button {
margin-top: 15px;
}
</style>
</head>
<body ng-app="CanvasTooltipApp">
<div ng-controller="CanvasTooltipCtrl" class="container">
<canvas id="myCanvas" height="300"></canvas>
<button type="button" ng-click="clickMe()" tooltip="The Tooltip Text">Click Me</button>
</div>
<script src="https://cdnjs.cloudflare.com/ajax/libs/angular.js/1.3.15/angular.js"></script>
<script src="https://cdnjs.cloudflare.com/ajax/libs/angular-ui-bootstrap/0.14.3/ui-bootstrap-tpls.js"></script>
<script>
angular.module('CanvasTooltipApp', ['ui.bootstrap']);
angular.module('CanvasTooltipApp').config(function($tooltipProvider) {
$tooltipProvider.options({popupDelay: 1500});
});
angular.module('CanvasTooltipApp').controller('CanvasTooltipCtrl', function($scope) {
var canvas = document.getElementById('myCanvas');
var ctx = canvas.getContext('2d');
ctx.beginPath();
ctx.arc(95, 50, 40, 0, 2 * Math.PI);
ctx.stroke();
$scope.clickMe = function() {
window.open('http://www.google.com', '_blank');
};
});
</script>
</body>
</html>
It is reproduced only on Chrome 49 on a Mac.
To reproduce: click on the button (before the tooltip appears!), a new tab would be opened. Wait a few secs. Perhaps open another new tab. Then close all tabs and go back to the original tab. The shape of the canvas should disappear.
I use AngularJS 1.3.15 and angular-ui-bootstrap 0.14.3. It does not seem to be reproduced with a plain bootstrap tooltip. Only with the angular-ui-bootstrap it is reproduced.
Upgrading the angular-ui-bootstrap version does not help.
It is not reproduced on other browsers, or on other OSs.
That's it, I think. I hope you even succeed in reproducing it without a plunker/fiddle.
Thank you very much in any case! Daniel
