我在单独的控制器内有两个按钮。
<div ng-controller="aCtrl">
<button class="addButton" ng-click="toggle()"> Add </button>
<form ng-hide="myVar" ng-submit="submit()">
<input ......
<input ......
</form>
</div>
<div ng-controller="bCtrl">
<button class="EditButton" ng-click="toggle()"> Add </button>
<form ng-hide="myVar" ng-submit="submit()">
<input ......
<input ......
</form>
</div>
注意:切换只是在后端切换hide / show bool
正如您在点击Addbutton
时所看到的那样,它会为aCtrl
显示EditButton
和bCtrl
的表单。当前布局的结果是当Add Buttons表单展开时它会向下推动EditButton。我不认为这可以通过CSS修复,因为它是HTML的逻辑流程。
我正在寻找能让我在页面流程顶部显示按钮的解决方案,然后是下面的表格。
例如我试过:
<button ng-controller="aCtrl" class="EditButton" ng-click="toggle()"> Add </button>
<button ng-controller="bCtrl" class="addButton" ng-click="toggle()"> Add </button>
<div ng-controller="aCtrl">
<form ng-hide="myVar" ng-submit="submit()">
<input ......
<input ......
</form>
</div>
<div ng-controller="bCtrl">
<form ng-hide="myVar" ng-submit="submit()">
<input ......
<input ......
</form>
</div>
这似乎无法发挥作用。

问题在于ng-hide
使用display: none
隐藏内容,导致元素占用的空间崩溃。
您需要visibility: hidden
同时隐藏元素,但保留空间。
因此,请使用ng-class
代替ng-hide
:
<div ng-controller="aCtrl">
<button class="addButton" ng-click="toggle()"> Add </button>
<form ng-class="{ 'hidden' : myVar }" ng-submit="submit()">
<input ......
<input ......
</form>
</div>
<div ng-controller="bCtrl">
<button class="EditButton" ng-click="toggle()"> Add </button>
<form ng-class="{ 'hidden' : myVar }" ng-submit="submit()">
<input ......
<input ......
</form>
</div>
和CSS
.hidden {
visibility: hidden;
}
这是一个实时样本:
var myApp = angular.module('myApp',[]);
function aCtrl($scope) {
$scope.myVar = true;
$scope.toggle = function () {
$scope.myVar = !$scope.myVar;
}
}
function bCtrl($scope) {
$scope.myVar = true;
$scope.toggle = function () {
$scope.myVar = !$scope.myVar;
}
}
.hidden {
visibility: hidden;
}
<script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.2.23/angular.min.js"></script>
<section ng-app="myApp">
<div ng-controller="aCtrl">
<button class="addButton" ng-click="toggle()"> aCtrl.Add </button>
<form ng-class="{ 'hidden' : myVar }" ng-submit="submit()">
<input type="text" value="aCtrl.form">
</form>
</div>
<div ng-controller="bCtrl">
<button class="EditButton" ng-click="toggle()"> bCtrl.Add </button>
<form ng-class="{ 'hidden' : myVar }" ng-submit="submit()">
<input type="text" value="bCtrl.form">
</form>
</div>
</section>
bCtrl.Add
是否可见,aCtrl.form
按钮都会保留在原位。

它可以通过css完成,只需将两个包装在一个div中,位置为:relative,然后将position:absolute添加到addButton和editButton以及上/左/右定位值。
<div class="formContainer">
<div ng-controller="aCtrl">
<button class="addButton" ng-click="toggle()"> Add </button>
<form ng-hide="myVar" ng-submit="submit()">
<h1>Add form</h1>
<input type="text">
<input type="text">
</form>
</div>
<div ng-controller="bCtrl">
<button class="editButton" ng-click="toggle()"> Edit </button>
<form ng-hide="myVar" ng-submit="submit()">
<h1>Edit form</h1>
<input type="text">
<input type="text">
</form>
</div>
</div>
和css:
.formContainer {
position: relative;
width: 200px;
padding-top: 30px;
}
.addButton {
position: absolute;
top: 0;
right: 40px;
}
.editButton {
position: absolute;
top: 0;
right: 0;
}
这是一个有效的演示:Plunker CSS Only
还有另外一种方法,将它们放在父控制器中,这将控制在表单之间切换的逻辑,然后每个表单都有自己的控制器用于各自的功能。
这是第二个版本的工作演示:Plunker with parent Controller

以下是您在帖子中提到的示例。你可以把按钮放在控制器外面
var myApp = angular.module('myApp',[]);
myApp.controller('aCtrl', ['$scope', function ($scope) {
$scope.myVar = true
}]);
myApp.controller('bCtrl', ['$scope', function ($scope) {
$scope.myVar = true;
}]);
function getscope(ctrlName) {
var sel = 'div[ng-controller="' + ctrlName + '"]';
return angular.element(sel).scope();
}
function showForm(ctrlName) {
var $scope = getscope(ctrlName);
$scope.myVar = !$scope.myVar;
$scope.$apply();
}
<script src="//ajax.googleapis.com/ajax/libs/jquery/1.8.3/jquery.min.js"></script>
<script src="//ajax.googleapis.com/ajax/libs/angularjs/1.0.2/angular.min.js"></script>
<section ng-app="myApp">
<button class="addButton" onclick="showForm('aCtrl')"> aCtrl.Add </button>
<button class="EditButton" onclick="showForm('bCtrl')"> bCtrl.Add </button>
<div ng-controller="aCtrl">
<form ng-hide="myVar" ng-submit="submit()">
<input type="text" value="aCtrl.form">
</form>
</div>
<div ng-controller="bCtrl">
<form ng-hide="myVar" ng-submit="submit()">
<input type="text" value="bCtrl.form">
</form>
</div>
</section>

您的要求是否有两个控制器?
您可以拥有一个单独的按钮控制器,例如。使用$rootscope
变量btnCtrl和toogle值。如下。
<button ng-controller="btnCtrl" class="EditButton" ng-click="toggle()"> Add </button>
<button ng-controller="btnCtrl" class="addButton" ng-click="toggle()"> Add </button>
<div ng-controller="aCtrl">
<form ng-hide="$root.myVar" ng-submit="submit()">
<input ......
<input ......
</form>
</div>
<div ng-controller="bCtrl">
<form ng-hide="$root.myVar" ng-submit="submit()">
<input ......
<input ......
</form>
</div>
