Javascript 服务调用后控制器中未触发角度方法
我有一个angular服务,它获取作为承诺解析的currentuser对象。我有一个由在方法调用中调用的objectuserdetails填充的部分,但不幸的是,在解析承诺后调用方法调用时没有触发Javascript 服务调用后控制器中未触发角度方法,javascript,angularjs,angularjs-scope,Javascript,Angularjs,Angularjs Scope,我有一个angular服务,它获取作为承诺解析的currentuser对象。我有一个由在方法调用中调用的objectuserdetails填充的部分,但不幸的是,在解析承诺后调用方法调用时没有触发 .controller('AccountCtrl', [ '$scope', 'userService', '$compile', '$http', 'utility', 'cloudService', function ($scope, userService, $compile, $htt

请务必让我知道我遗漏了什么。如果我将用户详细信息移出cloudservice.fetchuser().then()它至少调用了该函数,但不确定当我将其放入其中时发生了什么,我现在正在绞尽脑汁10个小时
类似的此处创建的plunk
谢谢您在
$scope之前运行ng init
。getUserDetails
已添加到$scope
,因为这只发生在回调中,这就是出现问题的原因
我认为您可能过于关注一些基本示例。由于您异步获取数据,因此不需要ng init
您可以让控制器请求服务下载数据,当数据到达时,您可以将其分配给$scope.getUserDetails
,angular会将其显示在屏幕上
您可以看到更新的
如果我丢失了一些重要的内容,请告诉我。您应该将函数移到
cloudservice.fetchuser().then()
方法之外。getUserDetails
方法对于$scope
对象不可用,直到您调用cloudservice.fetchuser().then()
。但是您不能在您的部分代码中这样做
.controller('AccountCtrl', [
'$scope', 'userService', '$compile', '$http', 'utility', 'cloudService',
function ($scope, userService, $compile, $http, utility, cloudService) {
$scope.userdetails = {};
$scope.getUserDetails = function(service, user) {
if (service && service.isLoggedIn()) {
$scope.userdetails = JSON.parse(JSON.stringify(user));
}
};
$scope.downloadPageChk = $scope.paymentHistoryPageChk = $scope.manageGroupsPageChk = "hide";
$scope.getUserAttribute = function (param, x) {
return userService.getAttribute(param, x);
};
cloudService.fetchCurrentUser().then(function (newCurrentuser) {
if (newCurrentuser) {
$scope.currentUser = newCurrentuser;
$scope.getUserDetails(userService, newCurrentuser);
if (newCurrentuser == 'member') {
if (newCurrentuser.features.download) $scope.downloadPageChk = "show";
if (newCurrentuser.features.paymenthistory) $scope.paymentHistoryPageChk = "show";
if (newCurrentuser.group.enabled) $scope.manageGroupsPageChk = "show";
}
}
});
});
]);
如果只想初始化数据,则不需要
$scope.getUserDetails
函数和data ng init=“getUserDetails()”
Angular将执行服务fetchCurrentUser
功能,并在加载时填充$scope.userdetails
cloudService.fetchCurrentUser().then(function (newCurrentuser)
{
if (newCurrentuser)
{
$scope.currentUser = newCurrentuser;
if (userService && userService.isLoggedIn())
{
$scope.userdetails = JSON.parse(JSON.stringify($scope.currentUser));
}
if (newCurrentuser == 'member') {
if (newCurrentuser.features.download) $scope.downloadPageChk = "show";
if (newCurrentuser.features.paymenthistory) $scope.paymentHistoryPageChk = "show";
if (newCurrentuser.group.enabled) $scope.manageGroupsPageChk = "show";
}
}
}
}
看
编辑:
如果希望getUserDetails
函数在初始化后仍可触发,则应将其置于服务方法之外:
$scope.getUserDetails = function(){
if (userService && userService.isLoggedIn()){
$scope.userdetails = JSON.parse(JSON.stringify($scope.currentUser));
}
};
并根据需要触发它(通过视图中的
ng click=“getUserDetails()”
或控制器中的$scope.getUserDetails()
).我看不到ng init
指令和$scope有任何用处。getUserDetails
方法,角度双向数据绑定将处理承诺。我已经更新了相同的plunker。可能会提到演示中的成功
和有问题的代码中的之间的区别。OP在响应方面对待它们是一样的seNo我无法将函数移到cloudservice.fetchuser()之外。然后(),因为$scope.userdetails对象是使用从服务返回的newCurrentuser对象填充的,而且它是一个异步调用,所以我更新了答案,以显示如何提取getUserDetails
方法并在异步cloudService.fetchCurrentUser.then
方法中调用它。这很有效。但我的问题是..什么如果我必须在newCurrentuser对象可用后执行一个方法,比如调用ng init?@skm在我的回答中添加了解释,这就是你的意思吗?
