我有一些奇怪的问题与范围内方法的定义有关。一旦它被定义,当我想调用它(只需将其输入代码)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] = $scope.isAbsent(cached.lunchers.all[i]);
}
}
现在发生了一些奇怪的事情。你能看到:
console.log($scope.isVegie);
当我有:
$scope.selectedVegies[i] = $scope.isVegie(cached.lunchers.all[j]);
评论我可以在firebug中看到方法,当我取消注释它时,它会被取消定义...
有人有类似的问题吗?
注意:
ConfigurationService.getConfiguration()
这是方法:
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;
},
答案 0 :(得分:0)
发现了这个问题。事情是那个
$scope.isVegie
是在逻辑调用之后定义的。但是,当我没有其他部分时,我没有注意到。当它没有if-else时,它工作正常,即使方法被定义在“调用它的逻辑”之下。
这解决了这个问题。
