【问题描述】:
当用户尝试刷新或重新加载页面时如何实现对话框打开?
我尝试了许多链接,这些链接建议我扣除刷新的按键/keydown/beforeload/beforeunload,但这些都不起作用。
这里是,我试过了。与我的情况。
var App = angular.module('App', ['ngRoute']);
// configure our routes
App.config(function($routeProvider) {
$routeProvider
.when('/', {
templateUrl : 'home.html',
controller : 'mainController'
})
.when('/about', {
templateUrl : 'about.html',
controller : 'aboutController'
})
.when('/contact', {
templateUrl : 'contact.html',
controller : 'contactController'
});
});
App.controller('mainController', function($scope) {
//but not here if the user refresh the page
$scope.message = 'MainCtrl!';
});
App.controller('aboutController', function($scope) {
$scope.message = 'aboutController';
// if this is the current controller and page being refresh by the user activity
// prompt the user to save before you reload...
});
App.controller('contactController', function($scope) {
$scope.message = 'contactController';
// if this is the current controller and page being refresh by the user activity
// prompt the user to save before you reload...
});
in index.html
--------------------
<script>
//it is working . it is invoking in each page. But needs to invoke at certain controller means it should check
// it is current/exact page where user has to save data before reloading
jQuery(function () {
// to check and get page refreshed & reload
var myEvent = window.attachEvent || window.addEventListener;
var chkevent = window.attachEvent ? 'onbeforeunload' : 'beforeunload';
myEvent(chkevent, function (e) {
var confirmationMessage = ' ';
(e || window.event).returnValue = confirmationMessage;
return confirmationMessage;
});
if (myEvent) {
localStorage.clear();
// redirect to
$state.go('gotohome');
}
});
</script>
谁能给我任何适用于所有类型浏览器的功能示例?
对我来说太重要了,反正我做不到。
谢谢。
