我想隐藏我的头颅。
app.controller("kpiOverviewCtrl", function ($scope, $stateParams,) {
"use strict";
var setUpController = function () {
$scope.headmenu = $state.current.controller === "kpiCompareCtrl";
};
$rootScope.$on('$locationChangeSuccess', function () {
setUpController();
});
$rootScope.$on('$stateChangeSuccess', function () {
setUpController();
});
setUpController();
});
正如您在代码中看到的那样,它在控制器交换机上将headmenu
设置为true
。它工作正常。但是现在我想要从已经加载的控制器的headmenu
语句中将ng-click
设置为true。
app.controller("kpiDetailsCtrl", function ($scope, $state) {
"use strict";
$scope.loadDataForMonthView = function () {
$scope.errorNoDataForDate = false;
$scope.yearMode = false;
$scope.monthMode = true;
//Here I want to set $scope.headmenu = true;
//Other code.....
};
有什么好建议吗?

使用广播。它们是控制器之间通信的绝佳方式。
在主控制器中创建常规功能,您可以从控制器本身调用该功能。
app.controller('Main', function($scope) {
function setHeadMenu() {
// Set menu to true
}
$scope.$on('setHeadMenu', function() {
setHeadmenu(); // Fires on broadcast
})
});
创建一个ng-click,用于从其他控制器激发广播
app.controller('Second', function($scope) {
$scope.click = function() {
$scope.$broadcast('setHeadMenu'); // Send a broadcast to the first controller
}
});

第一个假建议:
$scope.loadDataForMonthView = function () {
$scope.headmenu = true; //(or false)
}
但很可能你正在使用一些异步调用,所以这样的事情会更好:
$scope.loadDataForMonthView = function () {
// First: you need some promise object
// the most simple is to use $http
var promise = $http({url: 'some.url', method: 'GET'});
promise.then(function() {
// the data have arrived to client
// you can hide or show menu according to your needs
$scope.headmenu = true; //(or false)
})
}
有关$http

您可以在kpiOverviewCtrl中向$ rootScope声明新方法:
app.controller("kpiOverviewCtrl", function ($scope, $stateParams, $rootScope) {
"use strict";
//your code...........
$rootScope.setUpController = setUpController;
});
然后从kpiDetailsCtrl控制器调用它:
app.controller("kpiDetailsCtrl", function ($scope, $state, $rootScope) {
"use strict";
$scope.loadDataForMonthView = function () {
$scope.errorNoDataForDate = false;
$scope.yearMode = false;
$scope.monthMode = true;
$rootScope.setUpController();
}
});
