AngularJs：传递给指令的四个参数之一是未定义的
我有一个模态视图（.jsp），它集成了指令（命名为＆＃39; querybuilder＆＃39;，图片中的黄色部分 - 一个js文件）。控制器（命名为＆＃39; addEditRuleSetCtrl＆＃39;）和指令包含在上层，包含似乎很好。我们从以下观点发起了指令：
self.fieldsDDE = [
{ name: 'FirstnameDDE' },
{ name: 'LastnameDDE' },
{ name: 'BirthdateDDE' },
{ name: 'CityDDE' },
{ name: 'CountryDDE' }
];
self.fieldsATT = [
{ name: 'FirstnameATT' },
{ name: 'LastnameATT' },
{ name: 'BirthdateATT' },
{ name: 'CityATT' },
{ name: 'CountryATT' }
];
self.fieldCodes = [];
self.ruleConditionSetOperators = [];
self.ruleConditionOperators = [];
其中＆＃34; addEditRuleSetCtrl.initSelectors（）＆＃34;启动传递给指令的所有参数：

这些参数以这种方式在控制器中声明：
AddEditRuleSetApp.directive('queryBuilder', ['$compile', function ($compile) {
return {
restrict: 'E',
scope: {
group: '=',
ruleConditionOperators: '=',
ruleConditionSetOperators: '=',
fields: '='
},
templateUrl: '/queryBuilderDirective.html',
compile: function (element, attrs) {
var content, directive;
content = element.contents().remove();
return function (scope, element, attrs) {
scope.fields = scope.$parent.fieldCodes;
scope.ruleConditionOperators = scope.$parent.ruleConditionOperators;
scope.ruleConditionSetOperators = scope.$parent.ruleConditionSetOperators;
window.alert("HEYYYYYY I'M CHANGING!!!!!! "
+ JSON.stringify(scope.group)
+ " ; "+ JSON.stringify(scope.ruleConditionOperators)
+ " ; "+ JSON.stringify(scope.ruleConditionSetOperators)
+ " ; "+ JSON.stringify(scope.fields));
scope.addCondition = function () {
scope.group.rules.push({
condition: '=',
field: 'Firstname',
data: ''
});
};
scope.removeCondition = function (index) {
scope.group.rules.splice(index, 1);
};
scope.addGroup = function () {
scope.group.rules.push({
group: {
operator: 'AND',
rules: []
}
});
};
scope.removeGroup = function () {
"group" in scope.$parent && scope.$parent.group.rules.splice(scope.$parent.$index, 1);
};
directive || (directive = $compile(content));
element.append(directive(scope, function ($compile) {
return $compile;
}));
}
}
}
}]);
问题是：传递给指令的四个参数中的一个（参数＆＃39; fieldCodes＆＃39;）是＆＃34;未定义＆＃34;虽然他们被定义，但以类似的方式传递。我已经清理了缓存并测试了所有可能的方法，但没有任何区别。因此相关的下拉列表是空的（在屏幕截图中的红色箭头下拉列表中）。任何线索？

在我第一眼看到该指令时，我认为您可能应该改变：
var test = scope.$parent.fieldCodes;
scope.fields = scope.$parent.fields;
要：
//var test = scope.$parent.fieldCodes;
scope.fields = scope.$parent.fieldCodes;
