1) The following Sticky Notes app is running perfectly under angular v1.0.0
http://jsfiddle.net/simpulton/VJ94U/
but does not run properly( I can't delete a note) under angular v1.4.7
http://jsfiddle.net/nnkcz4ko/
may I know why?
2) This is another problem(not related to the first one):
http://plnkr.co/edit/d3EwL2Jfzcpe84y01pLi?p=preview
in this app I could not figure out from where did the selected property come into existence in the statement ng-show="selected" in file my-pane.html. I can't see a $scope.selected defined anywhere in the code.
PS: I'm fairly new to angular, so a beginner-friendly answer will be much appreciated.
okay, I figured out that in problem 2) the selected property is set directly on the isolated scope, so it can be accessed directly from that scope(i.e. from inside the my-pane directive).

I am using Chartist JS for my charts in my Angular JS app. The issue is I am seeing this here. There is a JS bin that highlights the issue. The author gives a solution for it. The solution is doing DOM manipulations in Jquery which is easy to do. However with AngularJS the way you manipulate the DOM is via Directives. I have created a plunker here which highlights the same issue in Angular JS but I am confused as to how to put the solution provided by author into my Angular code.
Here is the solution
$('[data-tab]').on('toggled', function (event, tab) {
tab.find('.ct-chart').each(function(i, e) {
e.__chartist__.update();
});
});
Edit: As requested the JSFiddle is updated, so what I am trying to do is. I have three different tabs and three different graphs, whenever I click on them I should see the respective graph. To make the tab behavior possible I have written a basic code using scope and model. which facilitates the changing of tabs. The issue is that the chart is getting created for first or default tab but not for the second and third tab. There is a solution given by the author but I don't know how to implement that in AngualrJS
the jQuery solution that you post is basically finding all the chart references and then doing DOM manipulation and call the update() function.
The key is how to find the chart to update in Angular.
In this case, you can assign a variable when you create a chart. For example:
var chart4 = new Chartist.Bar('#chart4', data1);
var chart5 = new Chartist.Bar('#chart5', data2);
Now you have the reference of the chart. All you have to do is to call update() function to render the chart again.
if (value === "allDrivers") {
$scope.tab = "All";
chart4.update();
}
Here is the working plunker
One thing I like to point out is: right now you need to double click the tab in order to see the chart is being rendered or you resize the browser window. I am still trying to find a way to fix this. But at least this approach gives you an idea how to convert the jQuery solution to Angular solution.
I was able to solve this using angular.element() method. So if you wish you use jquery in your angular code. You have to do this via angular.element method. But make sure to include jquery before angular in your index.html
If jQuery is available, angular.element is an alias for the jQuery
function. If jQuery is not available, angular.element delegates to
Angular's built-in subset of jQuery, called "jQuery lite" or jqLite.
I did not know this. From here it was learning for me. Following advice of #pieterjandesmedt from this post. I was able to do this. For other people who want to learn how this works. I have created a GitHub repo which gives a solution to this issue. The link for problem is given in the question. Hope that helps
I am using UI Bootstrap for collapsing/expanding a div section based on user clicking a button similar to the example shown in the official site - UI Bootstrap-Collapse
I included the latest version of ui-bootstrap(0.14.2) but it was not showing the expected behavior. In particular the collapseDone() and expandDone() callbacks are never called after the $animateCSS is done the animations. (The animations are working properly, presumably because of the css transition property of the class 'collapsing' in twitter bootstrap.)
But when I inspected the UI Bootstrap site, I found that it's working properly as expected. (That's the class 'collapsing' is added during the animation and then removed after animation and then the class 'collapse' is added). So I checked the source code link for collapse collapse source code -github and found that finally is used for $animateCSS promise resolution rather than done in the ui.bootstrap.js code I included.
So could someone please explain the difference between finally and done methods of the $animateCSS function? The documentation [Angular Docs-$animateCSS][3] says that
there is also an additional method available on the runner called .done(callbackFn). The done method works the same as .finally(callbackFn), however, it does not trigger a digest to occur. Therefore, for performance reasons, it's always best to use runner.done(callback) instead of runner.then(), runner.catch() or runner.finally() unless you really need a digest to kick off afterwards.
So it looks like both should behave similarly. Could someone shed light on this, as there seems to be very little resources to learn about $animateCSS. (google search for $animateCss returns results for animate.css which seems to be part of the earler angular js verion (v1.2) - so that doesn't help)
I had forgotten to inject "ngAnimate" to my module. That way the animation by $animateCss was not successful, so the done() was never called. But finally will be called even if the animation is not successful.
I want to display the contents from my model in a div which is contenteditable. User will modify this content and it should get saved in my model. I have used the example provided at https://docs.angularjs.org/api/ng/type/ngModel.NgModelController.
The code is available at http://plnkr.co/edit/ruKtNfDWP17npbFU4Te9?p=info
var app = angular.module('docApp', []);
The issue is:
ng-model attribute does not output the data in the div as it does in the input control. Therefore I have to use binding expression.
Because of that editing goes beserk.
How do I get it right?
Thanks.
In my experience contenteditable is extremely tricky for angular to deal with. See this issue on github (which has been open for over 3 years) for a lengthy discussion. You may want to try some third party modules such as akatov/angular-contenteditable.
I´m trying to find a good way to use Baconjs together with Angularjs in conjuctions with Angular-Bacon.
Now digesting from Bacon to the Angular scope works perfectly fine but I´m stumbling with Angular-Bacons $scope.$watchAsProperty(property) within Angulars ng-repeat:
Let´s say I have the Angular scope $scope.databaserecords and render it out with:
<div ng-repeat="record in databaserecords">
Each of the records has a record.checked property and I want to handle all checked records together in one Bacon stream, for example to add a certain tag to all records at once.
At this point using $scope.$watchAsProperty(databaserecords) I get no Bacon events when checking or unchecking certain records, so how could I accomplish to receive these changes back in Bacon?
I might also mention, that using $scope.$watchAsProperty(property) out of ng-repeat, for example for input fields, works well without any problem.
Thanks for your help! :)
If I've understood correctly, your actual databaserecords remains the same throughout the scope, so you'll need to invoke $watchAsProperty with the objectEquality argument set to true:
$scope.$watchAsProperty("databaserecords", true)
By default angular opts to compare objects with a simple object equality check. In your case the list object remains the same, so a deeper check is necessary. This is already implemented in angular-bacon but it seems I've omitted it from the docs.
I'm using Backbone.js with mustache.js, and I'm loading my templates using ajax. my problem is that the templates are being loaded from cache(refreshing using ctrl+F5 if that matters!). Now I have made changes to the template but it's still loading the old version of it. It's working perfectly fine in incognito. Is there a way to prevent this? Maybe prevent Mustache from caching the template?
The code that renders the template is:
$.get(this.templatesPath + this.template, function(resTemplate){
var html = Mustache.render(resTemplate, that.personData);
that.$el.html(html);
});
My first thought was to use some other function instead of "Mustache.render()" like maybe "Mustache.to_html()". But looking at the
Source Code
reveals that to_html() merely calls render().
Any thoughts?
Apologies for digging up this very old question, but I was searching for the answer to a similar question and didn't end up finding it anywhere. This question is one of the first that shows up when searching "mustache disable caching".
I am using Mustache and Express with the mustache-express module. I was able to disable caching with the following:
const Mustache = require('mustache-express')();
delete Mustache.cache;
I hope this helps someone else in the future.
