Function 取消注释时AngularJS函数未定义

Function 取消注释时AngularJS函数未定义,function,angularjs,scope,promise,method-missing,Function,Angularjs,Scope,Promise,Method Missing,我有一些关于范围内方法定义的奇怪问题。一旦定义了它,当我想调用它时(只需将它输入代码),它就会消失。我有这部分代码 if (ConfigurationService.isConfigurationChanged() === true) { ConfigurationService.getConfiguration().then(function(data) { $scope.configuration = data.configuration; $scope.lunchers =

我有一些关于范围内方法定义的奇怪问题。一旦定义了它,当我想调用它时(只需将它输入代码),它就会消失。我有这部分代码

if (ConfigurationService.isConfigurationChanged() === true) {
ConfigurationService.getConfiguration().then(function(data) {
    $scope.configuration = data.configuration;
    $scope.lunchers = data.lunchers;

    $scope.configuration.vegies.all_in_one_group = data.configuration.vegies.all_in_one_group;

    var lunchersLength = data.lunchers.all.length;

    for (var i = 0; i < lunchersLength; i++) {
        $scope.selectedVegies[i] = $scope.isVegie(data.lunchers.all[i]);
        $scope.selectedSpecialGroup[i] = $scope.isInSpecialGroup(data.lunchers.all[i]);
        $scope.isAbsent[i] = $scope.isAbsent(data.lunchers.all[i]);
    }   
}); 

} else if (ConfigurationService.isConfigurationChanged() === false)  {

var cached = ConfigurationService.getCachedConfiguration();
console.log($scope.isVegie);
$scope.configuration = cached.configuration;
$scope.lunchers = cached.lunchers;

$scope.configuration.vegies.all_in_one_group = cached.configuration.vegies.all_in_one_group;

var lunchersLength = cached.lunchers.all.length;

for (var j = 0; j < lunchersLength; j++) {
    $scope.selectedVegies[i] = $scope.isVegie(cached.lunchers.all[j]);
    //$scope.selectedSpecialGroup[i] = $scope.isInSpecialGroup(cached.lunchers.all[i]);
    //$scope.isAbsent[i] = $scope.isAbsent(cached.lunchers.all[i]);
}
}
当我有:

$scope.selectedVegies[i] = $scope.isVegie(cached.lunchers.all[j]);
注释:我可以在firebug中看到该方法,当我取消注释它时,它将变得未定义

有人有类似的问题吗

注:

这种方法是:

            getConfiguration : function() {
            var deferred = $q.defer();
            $http({
                    method :'GET',
                    url : "cgi-bin/get_configuration.py"
                })
                .success(function(data, status, headers, config) {
                    if (status === 200) {
                        angular.copy(data, configStatus.currentConfig);// = data;
                        configStatus.configurationChanged = false;
                        deferred.resolve(data);
                    }
                })
                .error(function(data, status, headers, config) {
                    console.log(data);
                    console.log(status);
                    deferred.reject(data);
                });
            return deferred.promise;
        },

发现了问题。问题是

$scope.isVegie
在调用它的逻辑之后定义。然而,当我没有其他部分时,我没有注意到。当它没有if-else时,即使方法是在调用它的逻辑的“下”定义的,它也可以正常工作


这解决了问题。

哪里是
$scope.isVegie()方法。如果第一个条件为真,那么它可以找到它。在其他方面,如果它不能。。。另外,奇怪的是,当我评论这一行时:$scope.selectedVegies[I]=$scope.isVegie(cached.午餐者.all[j]);在else condition console.log($scope)中,将转储正确的作用域(内有isVegie),如果我删除注释,它将不会有任何方法。。。很奇怪
