I am trying to make a modal for login/register forms and wanted to make something that is reusable, I came across this blog post that goes through making a directive. I used that as well as angular-ui-bootstrap docs to make my modal. It does work, but the first time I click the button to pop the modal, it doesn't work. I can see the scope getting created using Batarang, but nothing pops. Subsequent clicks do work, and if I have 2 buttons, no matter which one I press first, it doesn't work, and after that either one works.
I made up a plnkr to show this. I am using templates etc so I added those. You can see that pressing "Register" or "Login" will not pop up the modal, but if you click again, the modals pop. You can also see the scope getting created on the first press with Batarang.
Thanks in advance for the help!
Edit:
I found some more information that might be helpful. The first time I click the link, the scope.closeFormModal gets called.
Try add:
scope.$watch(
function () {
return scope.formModal;
},
function (newData, oldData) {
if (newData === oldData) {
return;
}
if (newData) {
$compile($element.contents())(scope);
}
});
to link function that was returned from $compile function.

I have a case where in which 2 asides are loaded and I have to clear a variable when the aside is closed pressing ESC or by clicking outside the aside.
I searched online and found that the following code can be used in the case of a modal. What is the code for aside?
scope.$on('modal.hide', function() {
console.log('modal... -hide');
});
How to watch for an Aside closing in angular-strap
The above code is not working for aside.
Is this approach correct? Otherwise, please suggest a method.
In the above case the modal name is not specified. So when we have more than one modal or aside how do we differentiate the closing of the modal or aside? In the current case, I don't have to differentiate the modals. But how to catch the event differently?
Update
The following code woks for aside.
scope.$on('aside.hide', function() {
console.log('aside... -hide');
});
The second question of how to identify each aside closing differently needs to be found out now.
With v2.1.1 of angular-strap the hide event for $aside was changed to aside-hide.
The AngularJS framework invokes handlers of $scope/$rootScope events with arguments:
scope.$on('aside.hide', function(event, data) {
console.log('aside... -hide');
console.log(event);
console.log(data);
});
Use those arguments to get information about the event.
I have a collapsible sidebar navigation, and any time users click a link on it, I have the sidebar hide automatically. I achieve this in the run method by using the following code:
app.run(function($rootScope) {
$rootScope.$on('$routeChangeSuccess', function () {
$rootScope.closeNavigation();
})
});
Where app is my Angularjs module.
The problem is that it gets a little unintuitive to use, when you click a link in the navigation for the page you're already on, and then nothing happens. What I would like is to have the sidebar close anyway, so that the users still get focus on the content, even if it's the same content.
But Angularjs doesn't execute the $routeChangeSucess event, if there is no route change happening. So what can I use instead?
You simply need to use ng-show = isPanelVisible and ng-click = closePanel() on the html sidepanel tag (e.g. a <div>).
Then, define $scope.closePanel() in the controller associated to the actual view. For instance
$scope.closePanel = function() {
$scope.isPanelVisible = false;
}
See an example here. Code is here. Note that it doesn't use ng-show, but the behaviour is the same.
I have an odd situation. I am writing an angular + ionic app with a left slide menu and here is what I am trying to do:
1) Trap the Android back button
2) When you tap the back button, if the menu is not open, take you to the menu (open it)
3) If the menu is open and you hit the back button, exit the app
To trap the back button, I have this code in app.run (also tried relocating to a base controller and injecting it with $controller into other controllers, did not make a difference)
What I am noticing is that if I actually tap the 'menu icon' of the menu, the "isOpen" reliably prints true/false alternately as a I open and close the menu
But, when I tap the Android back button, it works the first time (prints true or false), but every subsequent tap does not change the isOpen state, while the menu actually toggles.
This therefore makes it impossible for me to programmatically detect if the menu is open or close within the android back button handler.
It's confusing me why this is only a problem within the android back handler, and not a problem when I tap the menu item. It's the same code that is called in both cases, which is
$ionicSideMenuDelegate.toggleLeft();
My Android handler code:
$ionicPlatform.registerBackButtonAction(function (event) {
$ionicSideMenuDelegate.toggleLeft();
$ionicSideMenuDelegate.$getByHandle('sideMenu').toggleLeft();
$timeout ( function() {
console.log ("Status of SIDE MENU IS : " + $ionicSideMenuDelegate.$getByHandle('sideMenu').isOpen());
},1000);
}, 100);
I've also set up a codepen, though not sure how one can test it on and android device, because every time I try and hit the backbutton on a codepen or jsfiddle, it makes the browser go back a page.
Any insight into what is going on? I've asked in the ionic forum, but haven't been able to find out why (yet) --> hence the post to the SO community in the hopes it reaches a wider audience.
registerBackButtonAction needs a priority to override the other actions:
The priorities for the existing back button hooks are as follows:
Return to previous view = 100 Close side menu = 150 Dismiss modal =
200 Close action sheet = 300 Dismiss popup = 400 Dismiss loading
overlay = 500
Your back button action will override each of the above actions whose
priority is less than the priority you provide. For example, an action
assigned a priority of 101 will override the 'return to previous view'
action, but not any of the other actions.
I've tested this code and it works as expected:
.run(function($ionicPlatform, $ionicSideMenuDelegate, $ionicPopup) {
$ionicPlatform.registerBackButtonAction(function(e) {
e.preventDefault();
if (!$ionicSideMenuDelegate.isOpenLeft()) {
$ionicSideMenuDelegate.toggleLeft();
} else {
navigator.app.exitApp();
}
}, 1000);
});
As you can see I've used priority 1000 to make sure that I override all the default actions.
I've also used preventDefault(). I don't think you need this but, just in case.
This bit of code only works for the left-side menu as I only check:
$ionicSideMenuDelegate.isOpenLeft()
and only open the left one:
$ionicSideMenuDelegate.toggleLeft()
but you can change it to work with the right menu as well.
UPDATE:
If someone is interested to find out more about Android and Back Button this is the best article I've read so far.
On the click of a button i want the page to scroll a particular div bottom.
The 1st time i click, the page is going to the very top and the initial url http://localhost:8000 becomes http://localhost:8000/#/bottom(why is it not going to the div i mentioned).
The 2nd time i click the button, the url becomes
http://localhost:8000/#/bottom#bottom and it goes to the div bottom(which is what i want).
How do i deal with this ?
code snippet
$location.hash('bottom');
$anchorScroll();
Thanks in advance
Do ask for more explanation if required . . .
I don't know if you still need help, but have you checked this question?
Anyway, I also use one button to do a anchor scroll:
<button ng-click="app.gotoAnchor('destination')">GO!</button>
(...)
<div id="destination" style="height:1px;"></div>
And I just used a combination of AngularJS documentation examples and the SO question I mentioned before, to make this function:
function gotoAnchor(anchor){
if ($location.hash() !== newHash) {
// set the $location.hash to `newHash` and
// $anchorScroll will automatically scroll to it
$timeout(function() {
$location.hash(anchor);
});
} else {
// call $anchorScroll() explicitly,
// since $location.hash hasn't changed
$anchorScroll();
}
}
Being the $timeout call the one that made this work better.
Hope this helps.

I have a lengthy form customers will need to fill out. If they click a link on a page, it will navigate away from that Controller and they will lose any data they may have already input.
If I can determine the form has not yet been saved, how can I intercept any click to the links on the page so I can ask the user if they want to save their form first?
No code yet- sorry. Many thanks.
I've written an angularjs directive that you can apply to any form that will automatically watch for changes and message the user if they reload the page or navigate away. #see https://github.com/facultymatt/angular-unsavedChanges
Hopefully you find this directive useful!
sorry for the late answer but mabye someone stumbles upon this and finds it useful. I have encountered the same problem and at the beginning i tryed to use the ng-dirty class applyed to the form element but because i had some custom controls the ng-bind won't be applyed when i changed some fields.
The best way i found so far is to detect when the model is changed with the use of $locationChangeStart event.
$scope.$on('$locationChangeStart', function (event, next, current) {
//we are about to leave the page so it's time to see if the form was modified by the user
if (!$scope.isFormClean())
{
event.preventDefault();
}
});
