I am trying to build an Angular JS app where a certain block of HTML is replaced by another one (both are input forms) and they should both be in the same location.
I have used ng-show/hide and it works with regards to the hiding/showing. The only problem is that the second peace of html doesn't appear on the same location as where the previous one was located but next to it (feels like the second one is still "there" but invisible.
Is there another way of doing this or does this work for anyone else?

I'm looking to add segment analytics to my JupyterLab extension. No worries if you've never heard of a JupyterLab extension - the best way to think about it: I get control over a single node in the DOM where I can place some HTML, so I'm doing the following:
function Welcome(props) {return <h1>Hello</h1>;}
ReactDOM.render(<Welcome/>, dom_element_i_control)
This all works fine - I'm now looking to add some analytics code to this. For example, I'd like to be able to:
See when my code is rendered
See when someone interacts with my rendered element (e.g. if there was a button in the Welcome function, when the user clicked on it).
However, segment is a JS library that is delivered as a script that you load into a webpage at the top in a string tag like:
<script>
!function(){var analytics=window.analytics=window.analytics||[];if(!analytics.initialize)if(analytics.invoked)window.console&&console.error&&...}}();
</script>
Where would I even put this code? I don't have control over the larger page + HTML, so I'm not sure where I can slap this so I can start using analytics.
Thanks for any information!
My workaround:
Instead of using the above linked segment script, I used the analytics-node package from segment.
I create an Analytics object right before ReactDOM.render - and then can use it wherever I want :)
Note that this will not work for anyone who uses an add blocker, obviously!
I want to show only the first N characters of content within draft js. However, it can't be just simply sliced because, there is a possibility of creating invalid DOM (example: opening of p tag but no closing p tag).
At the moment, I am just displaying all the content using "draft-js-export-html" and "dompurify" packages. Kindly let know of a way to create an except.
Found a package, that seems to working. It creates excerpts in Javascript from HTML content.

Using TextAngular for a rich text input box in a AngularJS/ Rails environment.
Running integration tests with Capybara/Selenium & Capybara-Webkit.
Tried to create an integration test that inputs text into the text area for a test. However, I have not been able to successfully do this.
The thing that has prevented me is the text input box id changes ever time the test loads or page loads. So I used the below class, which is used in the text angular tests. With:
find('textarea.ta-html.ta-editor')
I used this as i know it works and the javascript tests written for text angular used this. text angular github tests
However, when i try and set the text area with a text value:
find('textarea.ta-html.ta-editor').set("Upgraded to SSD")
I get:
Failure/Error: find('textarea.ta-html.ta-editor').set("Upgraded to SSD")
Selenium::WebDriver::Error::ElementNotVisibleError:
Element is not currently visible and so may not be interacted with
How can I set a value for the text area using Capybara?
The element that matches textarea.ta-html.ta-editor is hidden on the page and is not the element a user interacts with. By design Capybara generally requires you to interact with the elements a user would interact with so you need to call #set on the visible element which is the previous sibling to the element you're attempting to interact with and matches div[contenteditable]. You don't show your HTML but hopefully you have a containing element you can scope to so you can do
find('<container_selector> div[contenteditable]').set(...)
or
find('<more_general_container_selector>', text: '<label text or something else in the container>').find('div[contenteditable]').set(....)
If you only have one of this type of field on the page you can probably get away with
find('.text-angular div[contenteditable]').set('Upgraded to SSD')
Note: If using the selenium driver it has a limitation that it can only interact with the main contenteditable element and not with the children that get created inside it. I'm not sure if the other capybara drivers have the same issue.
I was watching some videos on Egghead.io about AngularJS. The creator of the videos uses Webstorm (and, I believe, works for them). One feature I noticed is that he can set different syntax highlighting within different scopes or quotation marks. So, in code like the following (from an AngularJS directive)
return {
template: '<div>something</div>',
// ^^^ these guys ^^^
}
...he can get the inside of the quotation marks to highlight as HTML.
I use Sublime Text 2, and am fairly wedded to it. Is there an existing feature/plugin for Sublime that could handle a case like this? If not, is something like this technically possible using the Sublime Text 2 API?
I don't think it's built in, but it's certainly possible. I've been doing some work with graphviz and wanted to do something similar. Labels can be generated with html like syntax. Anyways, I played around with the .tmLanguage file and added a new pattern to match the context where html like entries were valid (I look for label = <). The patterns I used for the captures aren't that good, but it works for fine for me. This give me the following, which I think is similar to what you are looking for.
I don't know anything about AngularJS, so I can't help you with anything specific to that, but it is certainly possible. Note that in the image below, the last <table></table> are just to show that highlighting doesn't occur there.
Edit:
Forgot to include this in the original post, but here is my updated tmLangauage file. That first pattern is what I added(link). I used PlistJsonConverter to go from JSON to plist, then saved the file as .tmLanguage. Hope this helps.
#skuroda is right, I implemented #skuroda's code with an additional plugin to easily edit HTML within an AngularJS directive JS file. The result is HTML syntax highlighting within a directive JS file and additional functionality to remove string related delimiters while editing templates.... Sublime AngularJS HTML Template Plugin
I have a fragment of html which is contained in a property of a templated EPiServer page, within that html there is an img tag which has a relative url in it.
When the page is viewed, I can see the src attribute of the tag has been altered to have the prefix /ProjectName/Templates/Pages/.
I understand that this is being done by HtmlRewriteToExternal so that image files that are stored alongside the aspx template (which does indeed live in Templates\Pages) are located correctly, however the image which is intended to be part of the html fragment is in my case actually stored under PageFiles/nnn/ (where nnn is actually the parent page's PageFolderID), and I need to somehow make the altered html reflect that.
I've created a class that inherits from FriendlyUrlRewriteProvider and registered my class. I can debug the application, and watch the requests go through the overridden methods, but I still can't see where the prefix is being added or get any idea how to change it. I can alter the src tag to a different relative path in my class, but the prefix is still being added.
I've read everything I can find on the EPiServer url rewriting, but can't find anything that hints as to where this prefix is being added or how to stop that or change it.

I'm open to completely different solutions for what I'm actually trying to achieve, which is as follows:
I have multiple independent sets of static html files and related image / css / js files, which I'm trying to store / publish with EPiServer. The structure of each set looks something like
setfolder/
htmlfileA.html
htmlfileB.html
css/
styles.css
images/
piccy1.png
piccy2.png
js/
magic.js
I've figured that I should create an EPiServer page for the set, and then child pages for each html file, storing the html from the files in a property of the child pages. Currently I'm storing the related static files in the PageFiles of the relevant setfolder page, as that seems to be the most logically consistent place to put them.
It's hard to give the best solution without seeing it all infront of you. But one easy way is to alter the HTML-code when you print the property to the page.
Like <%= ChangeRelativeLinks(CurrentPage["HtmlCode"] as string) %>
And in the ChangeRelativeLinks(string htmlCode) you do a regexp or similar that changes relative links and images to the pagedir as an absolute path.
If you are storing the images in PageFiles which is a Virtual Path Provider you should be able to get the url to your file simply by using the API. On the PageData class (ie CurrentPage in your template) you have a method called GetPageDirectory() which gets the page folder.
You can read more about VPP concepts here:
http://sdk.episerver.com/library/cms6.1/Developers%20Guide/Core%20Features/File%20System/File%20System%20and%20VPPs.htm
No need for a url rewrite provider for this I think.
