根据当前页面,我需要更改模板。我的问题是,如何将current
页面从controller
传递到directives
模板方法?
这是我的尝试:
var myApp = angular.module('myApp', []);
myApp.controller('main', function ($scope) {
$scope.template = "homePage";
});
var getTemplate = function (page) { //i need $scope.template as params
if (page == "homePage") {
return "<button>One Button</button>"
}
if (page == "servicePage") {
return "<button>One Button</button><button>Two Button</button>"
}
if (page == "homePage") {
return "<button>One Button</button><button>Two Button</button><button>Three Button</button>"
}
}
myApp.directive('galleryMenu', function () {
return {
template : getTemplate(template), //$scope.template need to pass
link : function (scope, element, attrs) {
console.log(scope.template);
}
}
})
更新
我正在尝试这样,但仍然会出错。将$route
注入directive
的正确方法是什么?
var galleryMenu = function ($route, $location) {
return {
template : function () {
console.log($route.current.className); //i am not getting!
},
link : function () {
}
}
}
angular
.module("tcpApp", ['$route', '$location'])
.directive('galleryMenu', galleryMenu);

您可以在指令声明中调用$routeParams
,以便在template
函数中使用它。
myApp.directive('galleryMenu', ['$routeParams', function($routeParams) {
return {
template: function () {
var page = $routeParams.page || 'homePage', // Define a fallback, if $routeParams doesn't have 'page' param
output;
switch (page) {
case "servicePage":
output = "<button>One Button</button><button>Two Button</button>";
break;
default:
case "homePage":
output = "<button>One Button</button>";
/*
NOTE: Or this other, it was confusing to tell which one to use
output = "<button>One Button</button><button>Two Button</button><button>Three Button</button>";
*/
break;
}
return output;
},
link: function(scope, element, attrs) {
/* ... */
}
}
}]);
如果您使用ui-router
从$routeParams
切换到$stateParams
。

您需要从$ state.current获取当前网址,并且可以在templateProvider的帮助下传入指令。
myApp.directive('galleryMenu', function () {
return {
templateProvider : getTemplate(template), //$scope.template need to pass
link : function (scope, element, attrs) {
console.log(scope.template);
}
}
来自getTemplate的可以返回$ state.current。希望如此,它会帮助你。
