[英]Function is not recognized by another function in angularjs
During loading of the partial Html with controller, my function named $scope.actionViewVisitors()
is recognized and runs without errors. 在使用控制器加载部分Html的过程中,我的名为
$scope.actionViewVisitors()
函数可以识别并且可以正常运行。 But whenever I use it inside another function on the same controller, it gives me an error: TypeError: $scope.actionViewVisitors is not a function
. 但是,每当我在同一控制器上的另一个函数中使用它时,都会给我一个错误:
TypeError: $scope.actionViewVisitors is not a function
。 Please see my code below: 请在下面查看我的代码:
angular.module("Visitor.controller", [])
// ============== Controllers
.controller("viewVisitorController", function ($scope, $rootScope, $http, viewVisitorService, viewAccountService, DTOptionsBuilder) {
$scope.visitorList = null;
$scope.viewAccountDetail = null;
$scope.avatar = null;
$scope.visitorDetail = null;
$scope.visitorBtn = "Create";
$scope.actionViewAccount = function () {
$scope.actionViewAccount = viewAccountService.serviceViewAccount()
.then(function (response) {
$scope.viewAccountDetail = response.data.account;
$scope.avatar = "../../avatars/" + response.data.account.AccountId + ".jpg";
})
}
$scope.dtOptions = DTOptionsBuilder.newOptions()
.withDisplayLength(10)
.withOption('bLengthChange', false);
// THIS ONE IS NOT RECOGNIZED
$scope.actionViewVisitors = function () {
$scope.actionViewVisitors = viewVisitorService.serviceViewVisitors()
.then(function (response) {
debugger;
$scope.visitorList = response.data.visitorList;
});
}
// I DON'T GET ANY ERROR HERE
$scope.actionViewVisitors();
$scope.actionViewAccount();
$scope.createVisitor = function () {
$scope.statusMessage = null;
if ($scope.visitorBtn == "Create") {
$scope.createVisitor = viewVisitorService.serviceCreateVisitor($scope.visitorDetail)
.then(function (response) {
if (response.data.response == '1') {
bootbox.alert({
message: "Successfully created a new visitor.",
size: 'small',
classname: 'bb-alternate-modal'
});
} else if (response.data.response == '0') {
bootbox.alert({
message: "Failed in creting visitor.",
size: 'small',
classname: 'bb-alternate-modal'
});
}
});
debugger;
$scope.visitorDetail = undefined;
// I GET THE ERROR WHEN I CALL THIS METHOD
$scope.actionViewVisitors();
}
}
})
// ============== Factories
.factory("viewVisitorService", ["$http", function ($http) {
var fac = {};
fac.serviceViewVisitors = function () {
return $http({
url: '/Visitor/ViewVisitors',
method: 'get'
});
}
fac.serviceCreateVisitor = function(visitor) {
return $http({
url: '/Visitor/CreateVisitor',
data: { visitor: visitor },
method: 'post'
});
}
return fac;
}])
You are overwriting the function with Promise
in the following line, thus the error is correct 您在下一行中用
Promise
覆盖了该函数,因此错误是正确的
$scope.actionViewVisitors = function () {
$scope.actionViewVisitors = viewVisitorService.serviceViewVisitors()
.then(function (response) {
$scope.visitorList = response.data.visitorList;
});
}
Remove $scope.actionViewVisitors =
删除
$scope.actionViewVisitors =
$scope.actionViewVisitors = function () {
viewVisitorService.serviceViewVisitors()
.then(function (response) {
$scope.visitorList = response.data.visitorList;
});
}
On the first call to the function you are changing it from a function to a Promise. 在第一次调用该函数时,您正在将其从函数更改为Promise。 Maybe you want to be returning the result instead?
也许您想返回结果呢?
$scope.actionViewVisitors = function () {
return viewVisitorService.serviceViewVisitors()
.then(function (response) {
debugger;
$scope.visitorList = response.data.visitorList;
});
}
