apologies but I am an absolute noob on this. I have implemented a CKeditor on my website using the below HTML:
<!doctype html>
<html>
<head>
<!--Define the character set for the HTML element -->
<meta charset="utf-8">
<!--Call the external script to use the CDN CKEditor in your page-->
<script src="//cdn.ckeditor.com/4.6.2/standard/ckeditor.js"></script>
<script type="text/javascript">
//Define an init function that sends the rich text editor contents to the page code
function init() {
//onMessage runs when the HTML element receives a message from the page code
window.onmessage = (event) => {
if (event.data == "x") {
CKEDITOR.instances.CK1.setData( '<p></p>' );
console.log(event.data,"ok");
} else {
//postMessage sends the contents of the CKEDITOR back to the page code
window.parent.postMessage(CKEDITOR.instances.CK1.getData(),"*");
console.log(event.data,"okd");
}
}
}
</script>
</head>
<body onload="init();">
<!--Define the HTML element as a textarea-->
<textarea name="editor1" id="CK1"></textarea>
<script>
//Use the CKEditor replace() function to turn our textarea into a CKEditor rich text editor
CKEDITOR.replace("editor1");
</script>
</body>
</html>
It works great but I have a line spacing issue where it looks like there is a line in between the paragraphs, but when it displays later on it is on top of each other. Is there anyway to reduce the spacing so the user realises they need to press enter again?
Image attached, first test is 1 press of enter after text (which looks like it has a line between but doesn't), second is 2 enters.
My issue is also that I am using Wix, so I can't host the config or whatever files to change. So it all needs to be from the html link.....
Thanks!
enter image description here
These lines of code will remove extra space
:host ::ng-deep .ck-editor__editable_inline p {
margin: 0;
}
Do you need to force the user to press Enter twice for a new paragraph? If so, try this:
CKEDITOR.addCss('.cke_editable p { margin: 0 !important; }');
CKEDITOR.replace('editor1');

Hi I have a problem that I can't quite solve. I'm a total noob with HTML/Javascript, so I'm not sure how to proceed. The instructions are in the code:
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<title>Q2</title>
<script type="text/javascript" src="342.js"></script>
<script type="text/javascript">
function swap() {
if (Math.random()>.5){
document.getElementById("c").style.display = 'none';
document.getElementById("f").src = "images/f.jpg";
} else {
document.getElementById("d").style.display = 'none';
document.getElementById("f").src = "images/f.jpg";
}
}
</script>
</head>
<body>
<p>Add code so that clicking the button changes either the src "c.jpg" or "d.jpg" to "f.jpg" The choice of which should be replaced
should be determined randomly.</p>
<img src="images/c.jpg" id="c"><br>
<img src="images/d.jpg" id="d">
<br><br>
<button type="button" onclick="swap()">OK</button>
</body>
</html>
The original problem had everything but the scripts. When I try this, I'm able to get the image c or d to disappear, but image f doesn't appear. I don't know how to get the image to show. getELementById won't work because I haven't made an id, but how do I do that without having image f showing? Any help is appreciated.
Seems you're missing html
Try add f html element for work:
<img src="images/f.jpg" id="f">
The p tag in the html is talking about c.jpg, d.jpg and e.jpg.
Its not talking about f.jpg, you may want to check that
with the assumption that it is e.jpg and not "f.jpb". And also assuming that you have e.jpg in your images folder. Below code will work fine (small modification in the script)
function swap() {
if (Math.random()>.5){
// document.getElementById("c").style.display = 'none';
document.getElementById("c").src = "images/e.jpg";
} else {
// document.getElementById("d").style.display = 'none';
document.getElementById("d").src = "images/e.jpg";
}
}

As you can see, it converts time AFTER you have to click on the button, I want it to show the output without needing to click on "try it" and the unconverted time to be hidden, so I just want the converted time to show when the user enters my website (not as alert, but in the content normally)
Cheers
In the example, you just need to remove the code in the tags from the function.
Eg:
<script>
var theDate = new Date(Date.parse('06/14/2020 4:41:48 PM UTC'));
document.getElementById("demo").innerHTML = "Local date Time: "+theDate.toLocaleString();
</script>
Then you code will run whenever the page loads and not onclick. To remove the unconverted time and button you just need to remove them from the HTML.
Thanks,

please help me with this.
I am using ck editor 4.
The data is required in a particular font style, font size, and font color.
The user will get the data from an external source and the user has to paste the data in the CKeditor.
so whenever the user will paste the data, he will have to apply style, size, and color. I want to automate this so that whenever some data is pasted in the CKeditor these styles are auto-applied.
is there any way to automate this? If yes, how?
I looked into the API docs and searched on google but couldn't find the answers.
Look at CKEditor's Clipboard Integration.
You can customize the pasting of data on the paste event.
Here's a simple example of pasting text with bold and italic properties:
CKEDITOR.replace('editor', {
}).on('paste', function (evt) {
evt.data.dataValue = '<span><b><i>' + evt.data.dataValue + '</i></b></span>';
});
Complete example:
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="utf-8">
<title>CKEditor: Customized Pasting</title>
<script src="./node_modules/ckeditor4/ckeditor.js"></script>
</head>
<body>
<textarea name="editor" id="editor" rows="10" cols="80">
</textarea>
<script>
CKEDITOR.replace('editor', {
}).on('paste', function (evt) {
evt.data.dataValue = '<span><b><i>' + evt.data.dataValue + '</i></b></span>';
});
</script>
</body>
</html>
Demo:
You can work on it further according to your own use case and customize it according to some existing styles or maybe write a custom plugin only to custom-paste your particular data to avoid overriding the default pasting behavior.
you can customize the content when on paste event is occurred, use this code
CKEDITOR.replace('my_editor', {
}).on('paste', function (event) {
event.data.dataValue = '<b><i>' + event.data.dataValue + '</i></b>';
});
My API generates dynamic HTML document and dumps it into a popup window like so:
var popup = window.open('', "_blank", 'toolbar=0,location=0,menubar=1,scrollbars=1');
popup.document.write(result);
After the document is reviewed by a user, they can print it calling
window.print();
Chrome handles it without any problems, but Firefox shows a Printer error:
"Cannot print this document yet, it is still being loaded"
Printer window opens only if I hit Ctrl+R.
It appears that $(document).ready() never happens in firefox and it keeps waiting for something to load.
Status bar in popup says Read fonts.gstatic.com
Here's a brief content of a document:
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml">

<meta http-equiv="Content-Type" content="text/html; charset=utf-8" />

<title>Invoice #15001</title>
<style>
...
</style>
</head>
<body>
<div id="invoice_body" >
...
</div><!-- Invoice body -->
</body>
</html>
I have a feeling it has something to do with Google fonts. Any help is appreciated
When you pass "" as the URL to window.open, Firefox loads 'about:blank' at which point script security is likely preventing you from pulling in external resources via http or https ...
I am able to reproduce your problem and have it popup with the same error when I try to print-- I was able to get it working by using a data url when calling window.open ...
Based on your example, result is a string containing the HTML for the popup, so you would call window.open like this, and no longer use document.write for anything:
var popup = window.open("data:text/html;charset=utf-8,"+result, "printPopup", "toolbar=0,location=0,menubar=0,scrollbars=1");
I tested this with result being a string containing:
<html><head>
<link rel="stylesheet"href="https://fonts.googleapis.com/css?family=Tangerine">
<style> body { font-family: 'Tangerine', serif; font-size: 48px; } </style>
<title>Test</title></head>
<body>
<div>Testing testing</div>
<div>Print</div>
</body>
</html>
And clicking the print link worked as expected...
I had to go an extra mile, but:
I added server side code that would save a html file and pass a link to that file instead of html content:
ob_start();
include('ezts_invoice_template.php');
$dom = ob_get_clean();
$ezts_file_path = EZTS_PLUGIN_PATH.'kernel/tmp/'.session_id().'_tmp.html';
$ezts_file = fopen($ezts_file_path, 'w+');
$result = fwrite($ezts_file, $dom);
fclose($ezts_file);
print_r('{"result":"success", "file":"'.plugin_dir_url(__FILE__).'tmp/'.session_id().'_tmp.html"}');
in JS I open a popup by a link passed from PHP:
var popup = window.open(result.file, "_blank", 'toolbar=0,location=0,menubar=0,scrollbars=1');
and, finally, in template file I added event listener to request deletion of temporary file when the window is closed
window.addEventListener('beforeunload', function(event) {
window.opener.eztsApiRequest('deleteTempFile',
'',
function(result, status){ console.log(result); });
}, false);
It's not as easy, but it works great.
I am trying to add p5.js to the background of one section in my webpage. I am new to javascript and can't figure out how to bind the two parts together.
You need to add code in your setup.
Make sure you have the function in a script tag in the html as well.
Note you do not add # in the .parent().
var myCanvas = createCanvas(winWidth, winHeight);
myCanvas.parent("idnameofdiv");
if you are inserting multiple p5js canvas in one page and are already using the form new p5(sketch), you can just pass the id of your div as second parameter, like new p5(sketch, idnameofdiv)
Because the function sketch should be unique (if you don't use an IIFE), I like to put the id in the name of the sketch function as well
function sketch_idnameofdiv(p) {
p.setup = function () {
p.createCanvas(400,400);
}
p.draw = function () {
// stuff to draw
}
}
new p5(sketch_idnameofdiv, 'idnameofdiv')
if you don't need to insert multiple p5js canvas in one page, I guess you are looking for Michael Paccione's answer
P5.js gives you an html canvas that you can use for positioning your sketch.
Here is an example of using a canvas as the background of a div:
<!DOCTYPE html>
<html>
<head>
<style>
canvas {
position:absolute;
top:0;
left:0;
width:100%;
height:100%;
z-index:-1;
}
</style>
</head>
<body>
<h1>Heading</h1>
<p>paragraph 1</p>
<p>paragraph 2</p>
<script src="processing-1.4.1.min.js"></script>
<div id="canvasContainer">
<canvas data-processing-sources="rectangles.pde"></canvas>
</div>
</body>
This is Processing.js instead of P5.js, but the idea is the same. Try googling something like "html canvas as background" for a ton of results. Try something out, and post an MCVE if you get stuck.
To be more detailed about the answer:
function setup() is a function which executes ojnly once at the startup.
function draw() is a function which executes after setup() and it reloads on every frame of the picture.
The code goes like this:
<!DOCTYPE html>
<html>
<head>
<title>P5.js Example</title>
<script src="https://cdnjs.cloudflare.com/ajax/libs/p5.js/1.4.1/p5.js"></script>
<script>
function setup() {
var canvas = createCanvas(400, 400);
canvas.parent('canvasForHTML');
}
function draw() {
background(127);
}
</script>
</head>
<body>
<h1>Canvas for visualization</h1>
<div id="canvasForHTML"></div>
<p>Move your mouse around to see circles.</p>
</body>
</html>
