问题描述
plunker： http://plnkr.co/edit/wURNg8ByPYbEuQSL4xwg
example.js：
angular.module('plunker', ['ui.bootstrap']);
var ModalDemoCtrl = function ($scope, $modal) {
$scope.open = function () {
var modalInstance = $modal.open({
templateUrl: 'modal.html',
controller: 'ModalInstanceCtrl'
});
};
};
var ModalInstanceCtrl = function ($scope, $modalInstance) {
$scope.ok = function () {
alert($scope.text);
};
$scope.cancel = function () {
$modalInstance.dismiss('cancel');
};
};
index.html的：
<!doctype html>
<html ng-app="plunker">
<head>
<script src="http://ajax.googleapis.com/ajax/libs/angularjs/1.0.8/angular.js"></script>
<script src="http://angular-ui.github.io/bootstrap/ui-bootstrap-tpls-0.6.0.js"></script>
<script src="example.js"></script>
<link href="//netdna.bootstrapcdn.com/twitter-bootstrap/2.3.1/css/bootstrap-combined.min.css" rel="stylesheet">
</head>
<body>
<div ng-controller="ModalDemoCtrl">
<button class="btn" ng-click="open()">Open me!</button>
<div ng-show="selected">Selection from a modal: {{ selected }}</div>
</div>
</body>
</html>
modal.html：
<div class="modal-header">
<h3>I'm a modal!</h3>
</div>
<textarea ng-model="text"></textarea>
<div class="modal-footer">
<button class="btn btn-primary" ng-click="ok()">OK</button>
<button class="btn btn-warning" ng-click="cancel()">Cancel</button>
</div>
为什么我不能得到ModalInstanceCtrl定义的$ scope.text，即使我可以用$ scope.ok和$ scope.cancel？
Why I can't get the $scope.text defined in ModalInstanceCtrl, even though I can use $scope.ok and $scope.cancel?
推荐答案
看起来像一个范围问题。我得到它像这样的工作：
Looks like a scope issue. I got it to work like this:
var ModalInstanceCtrl = function ($scope, $modalInstance) {
$scope.input = {};
$scope.ok = function () {
alert($scope.input.abc);
};
$scope.cancel = function () {
$modalInstance.dismiss('cancel');
};
};
HTML
<textarea ng-model="input.abc"></textarea>
