prettifying innerHTML from Contenteditable div

I am trying to make an editor using contenteditible div(this div will show the rendered content but will also allow user to make changes by typing and other toolbar tools like bold, italic and so on), lets call this editor renditor, I also want to show the innerHTML of contenteditible div in another div for which I am using ace-editor for angular(https://github.com/fxmontigny/ng2-ace-editor) with mode html(lets call it coditor) but the problem I am facing is when I toggle from renditor to coditor(I take innerHTML of renditor div and plug it into coditor div) the renditor changes the look of innerHTML in its own mysterious way which results in overflows in coditor.
I have tried to use a pipe in angular with code provided from this answer (https://stackoverflow.com/a/43794051/4961540) but that even worsen the issue by breaking the html. I also feel renditor div is responsible for this because in past I didn't used separate div like coditor to show the code rather I just toggled in the same div using tags like pre and some other helper functions even then the html looked like it is looking now in coditor. Also it feels like renditor is responsible for it because I have observed when I set innerHTML of renditor to full html page source, it strips out html tags and some other tags so it is indeed making some changes to innerHTML and also how it looks.
<div class="mat-typography textBox editable" style="margin: 16px;"
[hidden]="isSourceVisible"
(input)="mSimpleTask.html=$event.target.innerHTML"contenteditable="true">
</div>
<div class="ace_tooltip" [hidden]="!isSourceVisible" ace-editor
[(text)]="mSimpleTask.html"
[mode]="'html'"
class="textBox ace-editor"
[theme]="'eclipse'"
[readOnly]="false"
[autoUpdateContent]="true"
[durationBeforeCallback]="1000"
(textChanged)="this.mSimpleTask.html=$event;"
style="overflow-wrap: break-word;margin: 16px">
</div>
I am looking to convert/extract innerHTML from renditor in such a way that html looks neat with proper line breaks and no overflows in coditor. Can you throw some light on how I can achieve that or even better if you can provide code with your implementation in the past ?

Convert HTML with CDN Libraries and External stylesheets to PDF

I designed my resume with bootstrap and material design lite, now I want to convert the html page to pdf file.
I tried some libraries (jsPdf) and some tools (html2pdf, princexml), it produces the pdf file but the problem is, that pdf is not what it looks in the html page.
There is no styles, the output i am getting is similar to pressing ctrl+p` in browser.
My question is,
Is there any tools or libraries for my problem ?
or
Is there any options in above mentioned tools that i can use?
pdf outputs

Try this converter WKHTMLTOPDF on your back-end. It outputs exactly what your see in you browser. It supports html, css and even js. Wkhtmltopdf based on webkit.
Using runtime it can be used like that
wkhtmltopdf http://google.com google.pdf
In your case, it seems that wkhtmltopdf can not load css. Check right css include path. Do not use relative path.

Your problem is the Bootstrap library, not any plugins or PDF tools you are using. It removes most styles when you "print" a web page, including print to PDF. My company, the DocRaptor HTML to PDF service, has a great blog post with a list of suggested fixes for getting Bootstrap styles to print correctly, but they could be summarized as:
Print using screen CSS mode/rules, not print. Otherwise, you have to a lot of overrides for Bootstrap to get it to work right. Much easier to just make the renderer use screen mode.
Bootstrap will think most PDFs are an extra small device, like a cell phone, so you have to either adjust your breakpoints or your in-code column definitions.
If your last column drops to a new row, this is because Bootstrap defines the width for many columns as XX.66666667%. The PDF engine adds all these up, and because of the 7 at the end, it is technically greater than 100%. Since the row width is over 100%, it bumps the last column to a new row. the fix is to override Bootstrap's column widths (handy Gist file for that).

jsPDF is able to use plugins. In order to enable it to print HTML, you have to include certain plugins and therefore have to do the following:
Go to https://github.com/MrRio/jsPDF and download the latest Version.
Include the following Scripts in your project:
jspdf.js
jspdf.plugin.from_html.js
jspdf.plugin.split_text_to_size.js
jspdf.plugin.standard_fonts_metrics.js
If you want to ignore certain elements, you have to mark them with an ID, which you can then ignore in a special element handler of jsPDF. Therefore your HTML should look like this:
<!DOCTYPE html>
<html>
<body>
<p id="ignorePDF">don't print this to pdf</p>
<div>
<p><font size="3" color="red">print this to pdf</font></p>
</div>
</body>
</html>
Then you use the following JavaScript code to open the created PDF in a PopUp:
var doc = new jsPDF();
var elementHandler = {
'#ignorePDF': function (element, renderer) {
return true;
}
};
var source = window.document.getElementsByTagName("body")[0];
doc.fromHTML(
source,
15,
15,
{
'width': 180,'elementHandlers': elementHandler
});
doc.output("dataurlnewwindow");
For me this created a nice and tidy PDF that only included the line 'print this to pdf'.
Please note that the special element handlers only deal with IDs in the current version, which is also stated in a GitHub Issue. It states:
Because the matching is done against every element in the node tree, my desire was to make it as fast as possible. In that case, it meant "Only element IDs are matched" The element IDs are still done in jQuery style "#id", but it does not mean that all jQuery selectors are supported.
Therefore replacing '#ignorePDF' with class selectors like '.ignorePDF' did not work for me. Instead you will have to add the same handler for each and every element, which you want to ignore like:
var elementHandler = {
'#ignoreElement': function (element, renderer) {
return true;
},
'#anotherIdToBeIgnored': function (element, renderer) {
return true;
}
};
From the examples it is also stated that it is possible to select tags like 'a' or 'li'. That might be a little bit to unrestrictive for the most usecases though:
We support special element handlers. Register them with jQuery-style
ID selector for either ID or node name. ("#iAmID", "div", "span" etc.)
There is no support for any other type of selectors (class, of
compound) at this time.
One very important thing to add is that you lose all your style information (CSS). Luckily jsPDF is able to nicely format h1, h2, h3 etc., which was enough for my purposes. Additionalyl it will only print text within text nodes, which means that it will not print the values of textareas and the like. Example:
<body>
<ul>
<!-- This is printed as the element contains a textnode -->
<li>Print me!</li>
</ul>
<div>
<!-- This is not printed because jsPDF doesn't deal with the value attribute -->
<input type="textarea" value="Please print me, too!">
</div>
</body>

tinymce default applied (written) style

I'm using tinymce to edit some field in a web application.
I need to have an html result (after editing) with some specification.
For example: when I press enter tinymce create a new paragraph (that's ok, and I know this behaviour can be changed, but paragraph is ok).
What I need is a specific style to the paragraph be applied.
I saw there is the possibility to specify content_css, but this is a visual deformation of what is written in the edited html.
my need is when I press enter a paragraph with specific style (margin, alignmnent, ..) must be written directly in the edited html text.
e.g. <P style="margin-top:2px; margin-bottom:10px"> ...</P>
Is it possibile to define specific style to be applied to each html tags ?
I need this because after editing, the html content is used in another part of application, where I can not add additional style configurations.

Did you try that?
...
'content_css' : './path/to/your/styles.css',
...
styles.css
p {
margin-top:2px;
margin-bottom:10px
}
..I saw there is the possibility to specify content_css, but this is a visual deformation..
True, but don't forget that this visual deformation is extracted when you call tinyMCE.activeEditor.getContent().
Though, i'm not sure it will extract your specific styles applied to <p> (untested)

UPDATED
Ok, i have another suggestion using HTML parsing using this.
$html = str_get_html("<div>add here your HTML from tinymce editor <p></p></div> test <p></p>");
foreach($html->find("p") as $p) {
$p->style = "margin:2px 0 10px 0";
}
$html_modified = $html;
The $html_modified should contain the <p> with margin applied.

Yes it is possible in tinymce. Just go to Tools -> Source Code of the editor toolbar. Write your HTML code with style there. You can try yourself.

Adding text to a speech bubbles in real time

I have an image that will form the background of an html page, and I want to superimpose speech bubbles over it. I've figured out how to make bubbles with css, and set their placement. But I cannot figure out how I will populate the bubbles (the div elements). Text messages will populate files, and I need to grab the strings and display them in the bubbles, refreshing the bubble content as messages come in. Any thoughts?

Assuming one of your bubbles contains a DIV which looks like this:
<div id="bubble1">This is the text</div>
You can use Javascript to easily change the text content. Using a JS library like jQuery is recommended. Here is a code example which changes the text:
<script>
$(document).ready(function()
{
$('#bubble1').text('This is the changed text'); // to change the text
$('#bubble1').html('This has <b>some</b> formatting'); // to change the html
});
</script>
Don't forget to include jQuery itself with a line like:
<script src="http://code.jquery.com/jquery-1.8.3.min.js"></script>
I couldn't understand where you are getting your strings from, if you let me know, I could update the answer.
If you are unfamiliar with jQuery, take a look here.

I think this will answer your question:

Keep in mind that this is css3, so older browsers can have problems with that.

Unable to get/set contents of tiny mce editor

I am using Tiny MCE editor version : 3.5.7
I am using multiple instances of text editor on same page with unique IDs and I have wrapped these editors in a div to show and hide these editors. Everything was working fine. Now I want to clear the contents of the editor when user hide it (so that when it is displayed again the previous contents are removed). I tried to do it using tinyMCE.get('editorId').setContent(''), it works fine only once.... I mean once I have used the above function than I am unable to set or even get the contents of that editor instance. The structure that I have used is as follows:
<div id="parentDIV">
<div id="1_editor">
</div>
</div>
tinyMCE.init({
mode: "exact",
max_char: "2000",
elements: "1_editor",
// Setting up ToolBar
theme: "advanced",
theme_advanced_layout_manager: "SimpleLayout",
theme_advanced_buttons1: "bold,italic,underline, strikethrough, separator,justifyleft, justifycenter,justifyright, justifyfull, separator,bullist,numlist,separator,fontselect ,fontsizeselect",
theme_advanced_toolbar_location: "top",
theme_advanced_toolbar_align: "left",
});
To show and hide the editor I doing something like this:
$('#parentDIV').hide();
$('#parentDIV').show();
Can anyone help please?

I am not totally sure why this happens. One option is if an editor gets moved around the dom. For you it might be a better way to shut down your editors explicitly then to just hide them.
To shut down an edtor instance use:
tinymce.execCommand('mceRemoveControl',true,'editor_id');
To reinitialize use
tinymce.execCommand('mceAddControl',true,'editor_id');
