All I want to accomplish is to show a "loading ..." when the submit button is clicked using AngularJS.
I figured that should be quite easy using
<form ng-if="!export.buttonClicked">
... various input values without ng-model
<input type="submit" value="Start export" class="btn btn-default" ng-click="export.buttonClicked=true;">
</form>
<div ng-if="export.buttonClicked">
loading...
</div>
How could I be so wrong. Seems like Angular prevents the default form submission like this. Showing the loading div works quite fine, but I need the form to be submitted (The server has to calculate a lot so it responds slowly and I would like to show loading... instead of the Button once it has been clicked)
I can't use ng-submit because I have to combine AngularJS with Razor and I don't want no ng-form or ng-model...
Any ideas?
If you have an angular controller tied to the page or div, just use a function in your ng-click like this:
<div ng-controller="sampleController" style="text-align:center">
<button ng-click="buttonClickedFunction()">Submit</button>
<p>{{message}}</p>
</div>
Then in your controller:
yourAppName.controller('sampleController', function($scope) {
$scope.buttonClickedFunction = function() {
$scope.message = "Loading...";
// Whatever else you wish to do with your button/function.
};
});
This puts loading on the screen once button is clicked, if this is what you were shooting to do?

I am trying to create an xeditable form as demonstrated here: https://vitalets.github.io/angular-xeditable/#editable-form.
I have followed the instructions exactly but my form is not working. I want to save a resource, but when I click the Edit button, which should display the form, it seems to skip the editing stage and immediately triggers the saveResource function - which should only happen when the form gets saved.
I've compared my code to the documentation again and again and can't work out what I am doing wrong.
HTML
<form editable-form name="editResourceForm" onaftersave="saveResource()">
<p>
<strong editable-text="resource.title" e-name="title">
{{resource.title}}
</strong>
</p>
<div class="col-xs-12 col-sm-4">
<button ng-click="editResourceForm.$show()" ng-show="!editResourceForm.$visible">Edit</button>
<!-- buttons to submit / cancel form -->
<span ng-show="editResourceForm.$visible">
<button type="submit" class="btn btn-primary" ng-disabled="editResourceForm.$waiting">Save</button>
<button type="button" class="btn btn-default" ng-disabled="editResourceForm.$waiting" ng-click="editResourceForm.$cancel()">Cancel</button>
</span>
</div>
</form>
JS
app.controller('Ctrl', function($scope, $filter) {
$scope.resource = {
title: 'awesome resource'
};
$scope.saveResource = function() {
console.log("Save resource");
}
});
JSFIDDLE HERE
You can see that it is trying to save the form, because every time the Edit button is clicked, the console logs "Save resource". This should not happen when the edit button is clicked.
#ckosloski answered this on Github:
I think it's because your edit button does not specify a button type.
By default, the button type is submit. So you are clicking on the
button and it's submitting the form since it's a submit button. Try
adding type="button" to your edit button.
Adding this solved it, as you can see from the updated JSFiddle.
I've been struggling with a ng-hide issue in combination with using ui-router. Simple app. Index.html shows some data via the "notes" route, you click on "detail" and you go to the sub route "notes.note" to view the detail just below the other records. The "detail" html has a "Save" & "Cancel" button.
Now there is an "Add New" button when you are not viewing the detail with the attribute ng-hide="HideAddNew". "HideAddNew" is a $scope variable in the controller. When I click "detail" on a row I have this ng-click="toggleAddNew()" on the link which in turn calls this
$scope.toggleAddNew= function()
{
$scope.HideAddNew=($scope.HideAddNew ? false : true);
}
That works perfectly, my detail shows and my "Add New" button has disappeared. Now on the detail when I click "Cancel" it fire off the ng-click="hideData()" which calls the function:
$scope.hideData=function()
{
$scope.toggleAddNew();
$state.go('notes');
}
And now my "Add New" has disappeared even though the variable is set to false, i.e. Don't hide. I've tried $timeout in that "hideData" function and in the "toggleAddNew" function. I've tried putting "$scope.toggleAddNew();" after the "$state.go('notes');" too. I don't want to resort to manually adding and removing classes. AngularJS ver: v1.3.15 , ui-router ver: v0.2.13 Thanx all :)
EDIT
Would the below work Tony?
<button ng-if="HideAddNew" ng-click="SelectRoute('notenew')" class="btn btn-primary">
<span class="glyphicon glyphicon-plus -glyphicon-align-left"></span>Add New</button>
Perhaps you could simplify and use ng-switch instead.
Something like this:
<ul ng-switch="expression">
<li ng-switch-when="firstThing">my first thing</li>
<li ng-switch-when="secondThing">my second thing</li>
<li ng-switch-default>default</li>
</ul>
Alternatively, maybe you could use ng-if or ng-show instead of ng-hide, eg:
<p ng-if="HideAddNew">it's here!</p>
<p ng-if="!HideAddNew">it's not here.</p>
Edit
If I understand what you're trying to achieve exactly, I would use ng-show with an ng-click:
Controller:
$scope.addNew = false;
View:
<button ng-show="!addNew" ng-click="addNew = true">Add New</button>
<button ng-show="addNew" ng-click="save()">Save</button>
<button ng-show="addNew" ng-click="addNew = false">Cancel</button>
Example
Hello currently I have a html form like that:
<div ng-controller="DemoCtrl">
<form name="myForm" action="/a/url">
....
</form>
<button ng-click="next(myForm)">Klick me</button>
</div>
is there a way to access the form action ?
what i suggest you not to provide action name in the form, instead of that within ng-click action javascript method in JS file either use $http service or $window service.
This can happen with the following htmlcode:
<div ng-controller="DemoCtrl">
<button ng-click="next(myForm)">Klick me</button>
</div>
JS Code:
$scope.next = function (formObject) {
// whatever you want to do
}
$scope will pick all the object defined within form tag.
I am also new in ng, if anything wrong here please correct me.
I am working on a website that displays numerous articles. Each article has a comment section. I have effectively been able to recursively write the comments to the DOM with recursion inside an ng-repeat. However, I need to be able to click on a respond button on any of the comments (they display in a nested fashion) and for a div to be inserted beneath the clicked button. This div would contain a text area for the comment they want to submit and a button. When this second button is clicked, the controller will save the comment to the database. I initially wanted to do this by directly manipulating the DOM from the controller. However, after further research, that would be in direct violation of the MVC/MVW pattern. I believe the correct answer is to create a custom directive. Please give me some insight on how to correctly do this. Any and all information would be very helpful. Thanks in advance.
If you want to add response div dinamically:
<div ng-repeat="article in articles" id="article-{{$index}}">
<p>{{article.content}}</p>
<button ng-click="addAnswer($index)">Add Answer</button>
</div>
js:
myApp.controller("articlesController", function($compile){
$scope.addAnswer = function (index) {
var div = $("<div></div>");
var input = $("<input type='text' ng-model='article.response'></input>");
div.append(input);
var button = $("<button>Send</button>");
button.attr("ng-click", "sendResponse(article)");
$compile(div)($scope);
$("#article-" + index).append(div);
};
});
You don't really need to make a directive to achieve this.
html:
<div ng-repeat="article in articles">
<p>{{article.content}}</p>
<input type="text" ng-model="article.response"></input>
<button ng-click="sendResponse(article)">Send</button>
</div>
js:
myApp.controller("articlesController", function($http){
$scope.sendResponse = function (article) {
console.log(article.response);
$http.post(url, article);
};
});
Of course, you can do it better by hidding input and send button, and show it after user clicks over an answer button.
I'm using AngularStrap with bootstrap.
I have a modal dialog that uses it's own controller. How can I close the modal using this local controller?
I instantiate the controller on a button like this:
<button type="button"
class="btn btn-success btn-lg"
bs-modal="modal"
data-template="user-login-modal.html"
data-container="body"
ng-controller="userLoginController"
>Click here to log in</button>
and the userLoginController has this:
$scope.authenticate = function(){
this.hide(); // this doesn't work
}
This is obviously just a demo, I want it to close on successful login, but this is where the code I'd use to close it would go.
I've tried instantiating the modal programmatically (use the $modal service to create the modal) but I haven't been able to figure out how to inject the controller through that method.
If I were to do something like emit an event from the modal using the bs-modal directive, how can I reference the modal to close it?
here's my plnkr:
http://plnkr.co/edit/m5gT1HiOl1X9poicWIEi?p=preview
When in the on-click function do
$scope.myClickEvent = function () {
this.$hide();
}
Figured out a good method:
I moved the ng-controller to the TEMPLATE and instantiate the modal using the provided modal service. I then use a rootscope broad cast to let everyone know that someone successfully logged in.
new controller code:
var loginModal = $modal({template:'/template.html', show:false});
$scope.showLogin = function(){
loginModal.$promise.then(loginModal.show);
}
$scope.$on("login", function(){
loginModal.$promise.then(loginModal.hide);
});
the button just looks like this now:
<button type="button"
class="btn btn-success btn-lg"
ng-click="showLogin()"
>Click here to log in</button>
and my template has the old ng-controller in the first tag.
I am probably too late, but just wish to share my answer. If all you need is hiding the modal after form success, then bind that $hide function to one of controller varriable.
<div class="modal" data-ng-controller="Controller" data-ng-init="bindHideModalFunction($hide)">
In the controller:
// Bind the hiding modal function to controller and call it when form is success
$scope.hideModal;
$scope.bindHideModalFunction =function(hideModalFunction){
$scope.hideModal = hideModalFunction;
}
I found all of the above answers way too complicated for your use case (and mine when I ran into this problem).
All you need to do, is chain the ng-click to use the built in $hide() function that angular strap bundles.
So your ng-click would look like: ng-click="authenticate();$hide()"
Using Angular and bootstrap if you want to submit data to controller then have the modal close just simply add onclick="$('.modal').modal('hide')" line to the submit button. This way it will hit the controller and close the modal. If you use data-dismiss="modal" in the button submit never hits the controller. At least for me it didn't. And this is not to say my method is a best practice but a quick one liner to get data to at least submit and close out the modal.
<div class="modal fade" id="myModal" ng-controller="SubmitCtrl">
<div class="modal-dialog" role="document">
<div class="modal-content">
<div class="modal-body">
<form ng-submit="submit()">
<input type="text" ng-model="name" />
<button type="submit" onclick="$('.modal').modal('hide')">Submit</button>
</form>
</div>
</div>
</div>
</div>
Perhaps open it with the service on click and have it close itself on the $destroy event?
$scope.openModal = function()
{
$scope.modal = $modal({
template: "user-login-modal.html",
container="body"
});
}
$scope.$on("$destroy", function()
{
if ($scope.modal)
{
$scope.modal.hide();
}
});
