How to open up an Ionic Modal upon click?
提问by TheAmazingKnight
I am new to Ionic and AugularJS and I am having a problem opening up a modal box upon click on a checkbox/radio button on the third option for hashtag search in the settings page. I have included an ng-controllerand ng-clickto take action. I looked in the debugger and it displayed an error:
我是 Ionic 和 AugularJS 的新手，在单击设置页面中用于主题标签搜索的第三个选项上的复选框/单选按钮时，我在打开模式框时遇到问题。我已经包含了一个ng-controller和ng-click来采取行动。我查看了调试器，它显示了一个错误：
GET http://localhost:8100/hashtag-modal [HTTP/1.1 404 Not Found 1ms]
GET http://localhost:8100/hashtag-modal [HTTP/1.1 404 Not Found 1ms]
I know that 404 Not Found means it didn't find the templateUrl but every nav page I have is in the index.html and they work fine except hashtag-modal.htmlin the app.jsfile. Why isn't it working and how do I resolve this issue?
我知道 404 Not Found 意味着它没有找到 templateUrl 但我拥有的每个导航页面都在 index.html 中，除了hashtag-modal.html在app.js文件中之外，它们都可以正常工作。为什么它不起作用，我该如何解决这个问题？
app.js
应用程序.js
// Navigation pages
app.config(function($stateProvider, $urlRouterProvider) {
$stateProvider
.state('index', {
url: '/index',
templateUrl: 'index.html'
})
.state('about', {
url: '/about',
templateUrl: 'about.html'
})
.state('settings', {
url: '/settings',
templateUrl: 'settings.html'
})
.state('hashtag-modal', {
url: '/hashtag-modal',
templateUrl: 'hashtag-modal',
controller: 'hashtag-modalCtrl'
})
$urlRouterProvider.otherwise("/index"); // if no url found, go back to index
})
// Hashtag Search option
app.controller('hashtagController', ['$scope', function($scope)
{
$scope.hashtagValue = 'Search'; // default value
$scope.hashtag = function()
{
$scope.hashtagValue = 'blackandwhitephotography'; // if selected, it'll display this value
};
}]);
// hashtag search modal
app.controller('hashtag-modalCtrl', function($scope, $ionicModal) {
$ionicModal.fromTemplateUrl('hashtag-modal.html', {
scope: $scope,
animation: 'slide-in-up',
focusFirstInput: true
}).then(function(modal) {
$scope.modal = modal;
});
$scope.openModal = function() {
$scope.modal.show();
};
$scope.closeModal = function() {
$scope.modal.hide();
};
// Cleanup the modal when we're done with it!
$scope.$on('$destroy', function() {
$scope.modal.remove();
});
// Execute action on hide modal
$scope.$on('modal.hidden', function() {
// Execute action
});
// Execute action on remove modal
$scope.$on('modal.removed', function() {
// Execute action
});
});
index.html
索引.html
<!-- SETTINGS -->
<script id="settings.html" type="text/ng-template">

</ion-modal-view>
</script>
Revised app.js
修改了 app.js
I added an $ionicModalto the hashtagControllerbut it is said Error: $ionicModal is undefined. Where else is it undefined?
我在 中添加了$ionicModal，hashtagController但据说Error: $ionicModal is undefined. 还有哪里是未定义的？
// Hashtag Search option
app.controller('hashtagController', ['$scope', function($scope, $ionicModal)
{
$scope.hashtagValue = 'Search'; // default value
$scope.hashtag = function()
{
$scope.hashtagValue = 'blackandwhitephotography'; // if selected, it'll display this value
$ionicModal.fromTemplateUrl('hashtag-modal.html', {
scope: $scope,
animation: 'slide-in-up',
focusFirstInput: true
}).then(function(modal) {
$scope.modal = modal;
});
$scope.openModal = function() {
$scope.modal.show();
};
$scope.closeModal = function() {
$scope.modal.hide();
};
// Cleanup the modal when we're done with it!
$scope.$on('$destroy', function() {
$scope.modal.remove();
});
// Execute action on hide modal
$scope.$on('modal.hidden', function() {
// Execute action
});
// Execute action on remove modal
$scope.$on('modal.removed', function() {
// Execute action
});
}
}]);
Revised label
修订标签
<label class="item item-radio" id="hashtagRadio" ng-controller="hashtagController" ng-click="hashtag();openModal();">
<input type="radio" name="settings-group" value="search">
<div class="item-content">
<span class="ion-pound"></span> <span id="hashtagInput">{{hashtagValue}}</span>
</div>
<i class="radio-icon ion-checkmark"></i>
</label>

ionic modal has nothing to do with routes.
离子模态与路线无关。
You just load a static html template from server, and that same html is shown in ionic modal with all the bindings.
您只需从服务器加载一个静态 html 模板，并以离子模式显示相同的 html 和所有绑定。
Instead of declaring a seperate controller, move it inside the same controller :
与其声明一个单独的控制器，不如将它移动到同一个控制器中：
app.controller('hashtagController', ['$scope', function($scope, $ionicModal) {
$scope.hashtag = function() {
$scope.hashtagValue = 'blackandwhitephotography'; // if selected, it'll display this value
$ionicModal.fromTemplateUrl('hashtag-modal.html', {
scope: $scope,
animation: 'slide-in-up',
focusFirstInput: true
}).then(function(modal) {
$scope.modal = modal;
$scope.modal.show();
});
};
$scope.openModal = function() {
$scope.modal.show();
};
$scope.closeModal = function() {
$scope.modal.hide();
};
$scope.$on('$destroy', function() {
$scope.modal.remove();
});
$scope.$on('modal.hidden', function() {
// Execute action
});
$scope.$on('modal.removed', function() {
// Execute action
});
}
Then in your HTML :
然后在你的 HTML 中：
<label class="item item-radio" id="hashtagRadio" ng-controller="hashtagController" ng-click="hashtag();openModal();">
<input type="radio" name="settings-group" value="search">
<div class="item-content">
<span class="ion-pound"></span> <span id="hashtagInput">{{hashtagValue}}</span>
</div>
<i class="radio-icon ion-checkmark"></i>
</label>
