我在下面有以下指令来创建标签功能。不幸的是,当我创建多个 这些标签的实例出错了。第一组选项卡仅切换第二组选项卡的显示。我错过了什么?
http://jsfiddle.net/U3pVM/19281/
core.directive("pane", function () {
return {
require: "^tabs",
restrict: "A",
transclude: true,
scope: {
title: "@"
},
link: function (scope, element, attrs, tabsCtrl) {
tabsCtrl.addPane(scope);
},
template:
'<div class="tab-pane" ng-class="{active: selected}"' +
'ng-transclude></div>',
replace: true
};
});
core.directive("tabs", function () {
return {
restrict: "A",
transclude: true,
//$scope is injected in to a controller via dependency injection hence the use of $scope not scope
controller: function ($scope, $element) {
var panes = $scope.panes = [];
$scope.select = function (pane) {
angular.forEach(panes, function (pane) {
pane.selected = false;
});
pane.selected = true;
};
this.addPane = function (pane) {
if (!panes.length) $scope.select(pane);
panes.push(pane);
};
},
template:
'<div class="tabs">' +
'<ul class="nav nav-tabs">' +
'<li ng-repeat="pane in panes"' +
'ng-class="{active:pane.selected}">' +
'<a href="" ng-click="select(pane)">{{pane.title}}</a>' +
'</li>' +
'</ul>' +
'<div class="tab-content" ng-transclude></div>' +
'</div>',
replace: true
};
});

您需要在tabs指令上添加一个隔离(或子)范围。
core.directive("tabs", function () {
return {
restrict: "A",
transclude: true,
scope: {}, // <== here it is!
controller: function ($scope, $element) {
var panes = $scope.panes = [];
$scope.select = function (pane) {
angular.forEach(panes, function (pane) {
pane.selected = false;
});
pane.selected = true;
};
this.addPane = function (pane) {
if (!panes.length) $scope.select(pane);
panes.push(pane);
};
},
template: '',
replace: true
};
});
这是因为您现在正在使用父作用域,因此为您使用的每个制表符指令覆盖该作用域上的面板属性。如果使用隔离范围,则为每个选项卡指令创建一个新的面板数组。

您也可以使用子范围,但这取决于您是否要使用父范围的属性。我现在要去隔离范围了。

在标签上设置范围:true!
http://jsfiddle.net/U3pVM/19289/
return {
restrict: "A",
transclude: true,
scope: true, <<missing this
这会创建一个子范围,如果您希望它是隔离的,请使用 -
scope: {},
