consider that I have several HTML templates and they have custom HTML tags. For ex: c-icon, c-text, c-button etc.
For some usecase(Display other content along with innerHTML), I need to access c-icon tag HTML inside c-text and append it to some text so that I can render it with some other html text. In future, I may have another component called c-badge and even I want to refer and render.
Could you please provide any suggestions for achieving the same?

I have below code for anchor tag, the display content of tag is a comment and needs to be displayed. With below code only "383:" is coming in UI but I need complete content. I cannot modify the display content but any setting change or any other way can be considered.

Am using it in QLabel in PyQt5 but suggestions from any folks related to either PyQt5 or HTML can be provided.
I only know how to do it in JavaScript:
document.querySelector("a").childNodes.forEach(c => console.log(c.nodeType,c.nodeValue))

I have a page that allows users to customise a design before downloading it. I have a list of designs that when clicked on display a different HTML layout. These HTML layouts are stored in a database as a string of HTML. To display these, i use:
<div [innerHTML]="myDesignHTML | safeHtml"></div>
As super basic example of one of the HTML strings is the following:
<div id="wrapper">
<div id="content">
<div id="title">titleText</div>
</div>
<div id="footer">
<p>footerText</p>
</div>
</div>
As I can't perform data binding on the actual HTML template that's inserted, I find the IDs of the elements and replace the 'placeholder' text with real user data. The issue I'm having is that my page also needs the ability to change colours of elements on the page. I've partially achieved this by doing the following for example:
document.getElementById("content").style.backgroundColor = color;
However, this doesn't always correctly update the DOM and feels a bit sketchy. Is there anything within Angular that allows the same functionality as [ngStyle] but within dynamic HTML templates that are inserted through [innerHTML]? When the user wants to change the colour of the background, or the text, it would be great to have a variable in the component.ts that get's updated and for the HTML template to react like [style.border-top-color]="mainCOlor" or something of the sort?
It seems that you can use the Renderer2 (see https://angular.io/api/core/Renderer2) in Angular. You would want a template reference do your div, and then you would use the nativeElement property to pull the current template. This is a better way to interact directly with the HTML inside of a div.
I am making a forum with markdown support.
I've been using meteor's markdown parser {{#markdown}} and have found something disturbing that I can't seem to figure out.
I am using {{#markdown}}{{content}}{{/markdown}} to render the content inserted into database.
The disturbing thing, for example, if someone writes up html without inserting it into the code block in the content...
example
<div class = "col-md-12">
Content Here
</div>
This will render as a column. They could also make buttons and etc through writing the HTML for it.
How to disable this behaviour so that when HTML is written it will not render into HTML but just simply show it as text?
You can write global helper, which will strip all html tags:
function stripHTML(string){
s = string.replace(/(<([^>]+)>)/ig, '');
return s;
}
Template.registerHelper('stripHTML', stripHTML)
Usage :
{{#markdown}}{{stripHTML content}}{{/markdown}}
Test it in console:
stripHTML("<div>Inside dive</div> Text outside")
I am making help content documentation for an already made software (the kind of which opens in every software when you press F1 or navigate to the Help section in the menu bar). I am using simple html/CSS/js pages to do so.
There is a ton of the same text descriptions of various software properties that appear in more than one page. The idea is to make a single text source file, where all the text descriptions are located and then use some sort of referencing to that specific text section wherever necessary.
Kind of a similar to using a CSS stylesheet to apply styles over all of the pages, only this handles text instead of styles. This way I would be able to change text in only one file and it would apply everywhere it is used.
I ran across the html SSI method, but this only includes the entire html page and not just a specific text section the way I would like to. I would strongly avoid using different file for each text section.
Can anyone please point me into the right direction here?
I think that you can make a JavaScript function that contains the common texts and use this functions in your code whenever you need them, for this the JavaScript that you create should be an external file and you can reference it in every html page you need it.
For example, you can have one function that returns "Hello World" and set this to a "p" element with the id="title". So in every page where you have an element with the id title you can call your JavaScript function to set its text to "Hello World". Use this link to find out more about this topic:
http://www.w3schools.com/js/js_htmldom_html.asp
UPDATE: I did a little test, i created the following JavaScript:
function helloTitle(){
var text = "Hello World!";
document.getElementById("title").innerHTML = text;
}
And referenced it in some HTML pages like this:
<script src="commonText.js" type="text/javascript"></script>
After that i only need to call the function in the element i want it to modify:
<p id="title"><script>helloTitle();</script></p>
This is a solution if you are only using JS, CSS and HTML. There should be other ways to achieve this.
Hope this information could help you!
I figured out how to do it a little more comforatbly on a large scale using the html command https://www.w3schools.com/tags/tag_iframe.asp
in your main html file you do:
<p> <iframe src="Text.html" width="100%" height="300" style="border:1px solid black;"> </p>
and then with some basic html formating insert whatever text u want
<html>
<body>
hmm idk what i should put here. Test
</body>
</html>
there will also be some css formatting needing to be done before it look perfect, but if you want to make multi line blocks I think this is the easiest way to.
I have an object that has a title and some text (item.itmTitle and item.itmText) which I am passing to an HTML template using Play's render() method. Within the template (which in this case is called "index.html) I am trying to display the contents of the item object:
.
.
.
<p class="title">${item.itmTitle}</p>
<div id="itemtext">${item.itmText}</div>
.
.
.
My problem is this: the contents of item.itmText are HTML formatted. What I would like is for the contents to be displayed as HTML, but what is happening is that Play is doing all necessary conversions to display the contents as text. In other words, if item.itmText has the following HTML:
<p>This is a paragraph formatted in HTML</p>
The play template converts the source as follows:
& lt;p& gt;This is a paragraph formatted in HTML& lt;/p& gt;
My question is: is there some way to stop this conversion and make the HTML appear on the page as renderable HTML?
Someone please advise.
${item.itmTitle.raw()}
You just need to make sure that these strings are guaranteed to be safe; e.g. if users are submitting the title or text you need to sanitize the content to prevent injection of javascript (or accidental breakage of your container tags).
