如果滿足特定條件,我需要用戶確認離開頁面。問題是位置變化不等待對話框來獲取用戶答案。不等待對話框內用戶回答的事件
這裏是我的代碼:
角模塊1:
...
function confirmLeavePage(e, newUrl) {
if(form.cod.value) {
customDialog.confirmDialog('Title','Leave?').then(
function(){
console.log('go to selected page');
},function(){
e.preventDefault();
});
}
}
$scope.$on("$locationChangeStart", confirmLeavePage);
...
角模塊2:
angular.module('dialog').service('customDialog', function($mdDialog, $q, $location) {
this.confirmDialog = function(title, content){
var deferred = $q.defer();
$mdDialog.show($mdDialog.confirm({
templateUrl:'confirmDialog.html',
title : title,
textContent : content,
ok : 'Confirm',
cancel: 'Cancel'
})).then(function() {
console.log('confirmed');
deferred.resolve();
}, function() {
console.log('abort');
deferred.reject();
});
return deferred.promise;
}
});
任何想法?
我更換 '的console.log( '去選擇的頁面');' 與 '$ location.path(NEWURL)' 但它再次觸發對話,因爲它的抓住了 '$ scope。$ on(「$ locationChangeStart」,confirmLeavePage);' 任何想法? – Larsen
