Utilizing an Angular directive to hide div elements when the user interacts outside of them has been effective. However, there is a specific issue that arises when clicking outside of a div on a button that toggles the visibility of the div.
The 'angular-off-click' callback successfully hides the container as intended but triggers the toggle function associated with the button shortly after, reopening the div. This conflicting behavior led to the removal of the 'off-click-filter', which provided exceptions using CSS selectors to prevent this interaction, ultimately avoiding unnecessary clutter in the HTML markup.
The desired outcome is for the toggle button to not activate its handler when clicking outside of the container.
Update: The problem primarily occurs on touch devices due to the default 300ms delay. When clicking outside the div, the callback initiates to hide the container and then, after the delay, the toggle function executes, causing the container to reopen. Conversely, on desktops with mouse clicks, the toggle function activates before the callback runs.
// Angular App Code
var app = angular.module('myApp', ['offClick']);
app.controller('myAppController', ['$scope', '$timeout', function($scope,$timeout) {
$scope.showContainer = false;
$scope.toggleContainer = function() {
$timeout(function() {
$scope.showContainer = !$scope.showContainer;
}, 300);
};
$scope.hideContainer = function(scope, event, p) {
$scope.showContainer = false;
console.log('event: ', event);
console.log('scope: ', scope);
console.log(p);
};
}]);
// Off Click Directive Code
angular.module('offClick', [])
.directive('offClick', ['$rootScope', '$parse', function ($rootScope, $parse) {
var id = 0;
var listeners = {};
var touchMove = false;
document.addEventListener("touchmove", offClickEventHandler, true);
document.addEventListener("touchend", offClickEventHandler, true);
document.addEventListener('click', offClickEventHandler, true);
// Rest of the code remains the same...
