I use CSS Variables in my NativeScript-Vue App, as described in the official documentation. I am looking for a way to read the value of a variable using JavaScript. Since there is no real browser engine, the established way doesn't work.
There is not much documentation, but there actually is a method mentioned in the API documentation: Style.getCssVariable(name). Using this method you can read CSS Variables, defined in the app.[s]css like this:
const color = this.$root.nativeView.style.getCssVariable('--color-primary')
console.log(color); // e.g. '#FF0000'
I would have expected this to also work on this.$el, but for some reason, this will only return null in my setup, allthough the variables are in the global scope and available in the style of the very same component. Maybe someone else can clarify, why this is.
in app.css
.main{
--primary: #02AC46;
--secondary: #ED7200;
}
in any .css
background-color: var(--primary);

Is it possible to customise the quick info section in the content editor to show additional information about the item?
Thanks
I think this would be quite tricky. If you look at Sitecore.Shell.Applications.ContentManager.Editor (in Sitecore.Client.dll), you'll see there is a RenderQuickInfo method. The HTML gets pieced together manually and is added to an EditorFormatter object as a literal control. All the classes involved are tightly integrated in to the application - there's no easily identifiable customisation point.
There are some pipelines associated with the rendering of the Content Editor,
renderContentEditor
getContentEditorFields
getContentEditorSkin
But I don't think these will provide an easy way in.
In general, I always think that if Sitecore haven't made part of the application easily customizable, then they probably did it on purpose.
One option could be a more js approach. The whole of the content editor is in the dom, albeit rather nested. It's slightly different but highlights the concept (http://blog.boro2g.co.uk/ever-edited-sitecore-web-db-mistake/).
I'd suggest if you use the example below in anger you make the xpath better - this was simply stolen from chrome dev tools.
As an example: with the following script pasted into the content manager.aspx file you can access some of the elements:
<script type="text/javascript">
window.onload=function(){
var text = getElementByXpath('//*[#id="EditorPanel"]/table/tbody/tr/td/table/tbody/tr[2]/td[1]');
if (text) {
text.innerText = "hi";
} else {
}
};
function getElementByXpath(path) {
return document.evaluate(path, document, null, XPathResult.FIRST_ORDERED_NODE_TYPE, null).singleNodeValue;
}
</script>
Which then allows you to update text (see screenshot):
quickinfo says hi
am using django ckeditor. Any text/content entered into its editor renders raw html output on the webpage.
for ex: this is rendered output of ckeditor field (RichTextField) on a webpage;
<p><span style="color:rgb(0, 0, 0)">this is a test file ’s forces durin</span><span style="color:rgb(0, 0, 0)">galla’s good test is one that fails Thereafter, never to fail in real environment. </span></p>
I have been looking for a solution for a long time now but unable to find one :( There are some questions which are similar but none of those have been able to help. It will be helpful if any changes suggested are provided with the exact location where it needs to be changed. Needless to say I am a newbie.
Thanks
You need to mark the relevant variable that contains the html snippet in your template as safe
Obviously you should be sure, that the text comes from trusted users and is safe, because with the safe filter you are disabling a security feature (autoescaping) that Django applies per default.
If your ckeditor is part of a comment form and your mark the entered text as safe, anybody with access to the form could inject Javascipt and other (potentially nasty) stuff in your page.
The whole story is explained pretty well in the official docs: https://docs.djangoproject.com/en/dev/topics/templates/#automatic-html-escaping
I have this::
FB::DOM::ElementPtr _element=m_host->getDOMWindow()->getDocument()->getBody()->getElementById("plugin0");
I got the element(i.e. object tag of the plugin that i wanted) by ID. It's compiling. I now want to SET its property from the JSAPI side...like border color style and width....
I went through this page . I could find only 1 method "setInnerHtml"...which sets something. What should i pass in its argument...?it has std::string type...so that I can manipulate the plugin's document. Any ideas...
Basically I want to set the attribute of a tag from PluginAPI side.....
Honestly? You'd be much better off putting the plugin in a div at 100%x100% and then managing the border of the div. For something like this I'd probably just use:
m_host->evaluateJavascript("document.getElementById('pluginCont').style.border = '1px solid black';");
That'll be the easiest. You could also look at the DOM abstraction code and add some tools for managing CSS; note that on IE you may need to use special activex methods to do this, which is why I dont' recommend just doing it through getDOMElement() (which is a shorthand, btw, for the long code you have in your example)
Is there any option for automatic spell checker( while typing) in tinymce?.
Try adding a javascript code that sets the spellcheck value to "true" after the TinyMCE editor loads.
This looks like it:
http://www.tinymce.com/wiki.php/Plugin:spellchecker
These look less useful:
http://www.tinymce.com/wiki.php/Configuration:gecko_spellcheck
http://www.tinymce.com/wiki.php/Plugin:iespell
Assuming you're using django-tinymce, it should be a matter of turning the plugin on in TINYMCE_DEFAULT_CONFIG. Then you can place the button where you want it. For example:
'theme_advanced_buttons2': "allmystuff,...,spellchecker",
'plugins': "abunchofplugins,...,spellchecker",
This assumes a folder named "spellchecker" under /tinymce/plugins which is available in your static files somewhere.
In my C++ app I'm embedding (via COM) a web browser (Internet Explorer) control (CLSID_WebBrowser).
I can display my own html in that control by using IHTMLDocument2::write() method but if the html has <img src="foo.png"> element, it's not displayed.
I assume there is a way for me to provide the data for foo.png somehow to the web control, but I can't find the right place to hook this functionality?
I need to be in full control of providing the content of foo.png, so work-arounds like using res:// protocol or saving to disk and using file:// protocol are not good enough. I just want to plug my code somehow so that when embedded CLSID_WebBrowser control sees <img src="foo.png"> in html data given with IHTMLDocument2::write() it will ask me to provide this data.
To answer my own question, the solution that finally worked for me is:
register custom IInternetProtocol/IInternetProtocolInfo/ via custom IClassFactory given to IInternetSession::RegisterNameSpace(). For reasons that seem like a bug to me, it has to be a protocol already known to IE (I've chosen "its") even though it would be much better if it was my own, unique namespace.
feed html data via custom IMoniker through IPersistentMoniker::Load() and make sure that IMoniker::GetDisplayName() (which is a base url according to which relative links in provided html will be resolved) starts with that protocol scheme (in my case "its://"). That way relative link "foo.png" in the html data will be its://foo.png to IE which will make urlmon call IInternetProtocol::Start() and IInternetProtocol::Read() to ask for the data for that url.
This is all rather complicated, you can look at the actual (BSD-licensed) code here:
http://code.google.com/p/sumatrapdf/source/browse/trunk/src/utils/HtmlWindow.cpp
You can embed a small webserver such as mongoose and reference those impage from there.
In mongoose, you can attach callback to specific path, thus returning images from C++ code.
We use this for our debugging tools, where each images is accessible from a web interface
The easiest solution would be a Data URI. You'd inline out the image directly with IHTMLDocument2::write().
