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：
<!doctype html>
<html ng-app="plunker">

<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$ scope.text在ModalInstanceCtrl中定义，即使我可以使用$ scope.ok和$ scope.cancel？
看起来像一个范围问题。我得到它工作这样：
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>
