$ window.alert在角度函數裏面不工作

Question

我想從一個angularJS函數彈出一個提示信息，但它不工作。

腳本

app.controller("APIController", function ($scope, $http) { 
$scope.saveSubs = function() { 
    var sub = { 
     UserName: $scope.username, 
     Password: $scope.password 
    }; 
    if ($scope.username === 'admin' && $scope.password === 'admin') { 
     window.location.href = '/Home/HotelSearchRedirect'; 
    } else { 
     $window.alert("User name or password wrong. please enter correct username or password."); 
    } 
};}); 

什麼是錯的代碼？

Answer 1

$window被注入。

app.controller("APIController", function ($scope, $http,$window) { 
$scope.saveSubs = function() { 
    var sub = { 
     UserName: $scope.username, 
     Password: $scope.password 
    }; 
    if ($scope.username === 'admin' && $scope.password === 'admin') { 
     window.location.href = '/Home/HotelSearchRedirect'; 
    } else { 
     $window.alert("User name or password wrong. please enter correct username or password."); 
    } 
};}); 

只需更換此代碼即可。希望這會幫助你。

Answer 2

，您應該使用的window代替$window，需要

window.alert("User name or password wrong. please enter correct username or password."); 

Answer 3

注入$window。

app.controller("APIController", function ($window, $scope, $http) { 
    // Code 
}); 

Answer 4

僅警告（「用戶名或密碼錯誤，請輸入正確的用戶名或密碼」）就足夠了。

無需窗口或$窗口。
