I've gotten reports of Operation Aborted errors from some developers who are using a JavaScript plugin and I'm trying to reproduce the problem to make a good recommendation for how they can fix their usage. I think the issue is that they are calling into DOM modifying functions from within the container that they'll be modifying. In those cases the plugin will be doing something equivalent to this
<div id="a">
<script>
document.getElementById('a').appendChild(document.createElement('div'));
</script>
</div>
I've seen this given as an example that will trigger an Operation Aborted error in IE7 but when I try it, everything seems to work fine. I'm using IE version 7.0.6002.18005, do I need an older version to trigger this behavior? Is there another way to trigger this?
I tried on a version of IE6 and was able to trigger operation aborted with the following HTML.
<html>
<body>
<div>
<script type="text/javascript">
var newElem = document.createElement('foo');
document.body.appendChild(newElem);
</script>
</div>
</body>
</html>
I guess newer versions of IE7 have been patched to fix this issue.

I downloaded React version 15 and created the following html document:
<!DOCTYPE html>
<html>
<head>
<script src="build/react.js"></script>
<script src="build/react-dom.js"></script>
</head>
<body>
<div id="container"></div>
<script type="text/jsx">
// React Code Goes Here
var MyComponent = React.createClass({
render: function(){
return (<h1>Hello, {this.props.name}!</h1>);
}
});
ReactDOM.render(
<MyComponent name="world" />,
document.getElementById('container')
);
</script>
</body>
</html>
The same works fine in jsfiddle but not on my machine. I want to avoid installing React dev tools or anything extra. Is that possible to get it to work with what I have or do I absolutely need to install something else?
There are tons of tutorials out there but they all seem to be missing something to get me started
If you're sure you have the react.js and react-dom.js files in a folder called build at the same level as that html page, the only thing missing would be:
a script include for babeljs in order for you to be able to use the JSX code you have in the body's script tag, add this to the <head> tag:
<script src="https://cdnjs.cloudflare.com/ajax/libs/babel-core/5.8.34/browser.min.js"></script>
As a precursory statement, I just want to make sure to mention that you probably won't want to do in-browser transpilation from JSX->JS for anything other than playing around with the technology. In a production environment you would want to precompile your JSX server-side or during a build step.
That being said, therein lies your problem: you're attempting to include JSX directly in the browser code, without including anything to do browser-side compilation for you.
Based on what I can see, it looks like the latest and greatest approach is to use <script type="text/babel"> now, instead of <script type="text/jsx">, and the compilation is accomplished via babel's browser.js.
This guide here appears to be mostly up to date: https://www.sitepoint.com/getting-started-react-jsx/
I'd say that if you are just starting react, a really good project to look at would be create-react-app. It does all the magic for you with one simple set up
For my team, we're between projects, but I'm performing some basic research on TypeScript and how to use Angular 1.x with it, considering that Angular 2 is still being baked. I usually use Plunkr to make small-scale prototypes so that we can see how something works and mess with it in-situ during tech demos and stuff.
The problem, though, is I tried to make a very basic Angular 1.x + TS setup in this plunker, but have been running into issues getting it to work properly. I think some of the problem is the client-side transpilation, but I'm sure that's not the only thing I'm messing up. Specifically...
View Code:
<!DOCTYPE html>
<html lang="en" ng-app="app">
<head>
<link rel="stylesheet" href="//maxcdn.bootstrapcdn.com/bootstrap/3.3.1/css/bootstrap.min.css" />
</head>
<body>
<div ng-controller="testController as ctrl">
<h1>{{ ctrl.testMethod() }}</h1>
</div>
<!-- Scripts... -->
<script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.4.7/angular.js"></script>
<script type="text/typescript" src="app.ts"></script>
<script type="text/typescript" src="controllers.ts"></script>
<script type="text/typescript" src="registrations.ts"></script>
<!-- Required for web transpilation... -->
<script type="text/javascript" src="//niutech.github.io/typescript-compile/js/typescript.min.js"></script>
<script type="text/javascript" src="//niutech.github.io/typescript-compile/js/typescript.compile.js"></script>
</body>
</html>
I got the client-side transpilation from this StackOverflow question, but that question's resolution was either, 'Just do it in Visual Studio!' or 'transpile your TypeScript, then plug the JavaScript into Plunkr,' which doesn't work for me, because my team is considering transitioning to TypeScript in the first place - we need to be able to work with typescript, thus the prototype to help us understand how it works. Additionally, that question notes that the transpilation parts are actually significantly outdated.
Question: First, is there an updated clientside TypeScript-to-JavaScript transpiler that I can link to in my prototype plunker? Second, are there any better resources to refer to on how to get Angular 1 to work with TypeScript? I've had very, very little luck finding anything that talks about how to make TypeScript work with Angular 1.x...
Edit:
Turns out you can use typescript on plnkr, which I just learned from the comments below http://embed.plnkr.co/suu7Yg/preview
For implicit mode all this requires is creating a file with the appropriate extension, i.e. script.ts or style.scss, and then referencing it in the head with the expected compiled extension, i.e. script.js or style.css. Very cool, plnkr!
I'm fairly certain Plunker doesn't support typescript (though of course I could be wrong) (edit: yup I was wrong, it's just not obvious that this is a feature). However, I can offer an idea for a possible solution of what you're trying to accomplish.
Try moving your small-scale prototypes and demos over to codepen instead. They're both pretty comparable apps I use all the time, and codepen currently supports typescript so if that's something you need to play with you got it.
It's hidden behind the little gear, along with external js file includes:
Turn on typescript:
Boom. Good to go for your live demos. Hope that helps!
As mentioned by #wesww in his amended answer, Plunker supports server-side compilation of TypeScript. What I mean by that is that when your TypeScript code is sent to the preview server, it is sent un-transformed.
Suppose you have a file script.ts, written in TypeScript, but the index.html of your project requests script.js, Plunker's preview server will compile your file on the fly and serve the compiled version.
You can configure how you want the TypeScript compiler to work by creating a tsconfig.json file (consistent with normal CLI usage) to define your settings.
Please see Definitive Guide to Comiplation on Plunker for more information.
I'm not familiar with plunk is but it's possible to transpile typescript in the browser by just including node_modules/typescript/typescript.js file and use the Compiler API. Checkout my Compiler API playground in the browser: https://cancerberosgx.github.io/typescript-in-the-browser/typescript-compiler/#example=tsTranspilingProject1

I went to the Angular Strap and took the scripts right off of the website
<script src="https://cdnjs.cloudflare.com/ajax/libs/angular-strap/v2.3.2/angular-strap.min.js"></script>
<script src="https://cdnjs.cloudflare.com/ajax/libs/angular-strap/v2.3.2/angular-strap.tpl.min.js"></script>
I added https: since I am running these without a server. However, I am getting 404's. Not sure why? I am using angular 1.4.6 which seems to be what is modeled.
That's because the urls are:
https://cdnjs.cloudflare.com/ajax/libs/angular-strap/2.3.2/angular-strap.min.js
And
https://cdnjs.cloudflare.com/ajax/libs/angular-strap/2.3.2/angular-strap.tpl.min.js

I am working on improving the UI of a website, and needed to use Semantic JS with it. The website was written in Angular, and the one piece of Semantic functionality that was not working was Dropdowns. The styling worked fine, but as soon as I tried to initialize the dropdown with a
$('...').dropdown({options});
I encountered a "$('...').dropdown is not a function" error. Looked around and nowhere mentioned the answer to my problem.
Since SemanticJS modifies the $ operator from Jquery, Jquery needs to be included before SemanticJS.
//Index.html//
<html>
<head>
</head>
<div ng-view></div>
<script src="jquery.blah.min.js"></script>
<script src="semantic.min.js"></script>

I could not get completion for my angular js eclipse based file. I know there could be lot of tutorials for setting up proper angular js for eclipse. But i read and followed the same and didn't worked still.
I also followed official link-> [Angular JS Eclipse Github setup link][1]
I installed, “Angular JS” from “Eclipse->Help Menu->Eclipse Marketplace”
It got installed and restarted.
Then, Eclipse->New->Static web project
Then, Convert the project to Angular. Right click Project, Configure-> Convert to Angular JS project
Then, Adding new html files. Right click Project, New->HTML file
Simple code:
<!DOCTYPE html>
<html lang="en-US" ng-app>
<script src="http://ajax.googleapis.com/ajax/libs/angularjs/1.3.14/angular.min.js"></script>
<body>
<div>
<p>Name : <input type="text" ng-model="name"></p>
<h1>Hello {{name}}</h1>
</div>
</body>
</html>
It works fine. Runs in the browser well.
My problem is, why does not it show the completion help when I type on "ng-" and use control + space in mac eclipse ? When I move cursor on "ng", it gives help of "div" tag rather than "ng" help. I want to just type "ng-" and get the list of available methods by just press control + space in mac eclipse
I can understand that there is some angular installation problem. But, none of the existing solution solved my issue.
