I am trying to add math formula in ckeditor, from editor should collect entire information(including formula) display on the same page in different div.
When I do with the following approach it is displaying math formula as text(not formatting as formula).
<html>
<head>
<script src="https://cdn.ckeditor.com/4.8.0/full-all/ckeditor.js"></script>
<script type="text/javascript" src="https://cdnjs.cloudflare.com/ajax/libs/mathjax/2.7.0/MathJax.js?config=TeX-AMS_HTML"></script>
<script>
function onSubmit(){
var data = CKEDITOR.instances.editor1.getData()
document.getElementById("show").innerHTML=data
}
</script>
</head>
<body>
<form action="#" >
<textarea rows="20" cols="70" class="ckeditor" id="editor1" name="test1">
</textarea>
<input type="button" value="save" onclick="onSubmit()" >
</form>
<div id="show" id='ed2'></div>
<script>
CKEDITOR.replace( 'editor1', {
extraPlugins: 'mathjax',
mathJaxLib: 'https://cdnjs.cloudflare.com/ajax/libs/mathjax/2.7.0/MathJax.js?config=TeX-AMS_HTML',
height: 320
} );
if ( CKEDITOR.env.ie && CKEDITOR.env.version == 8 ) {
document.getElementById( 'ie8-warning' ).className = 'tip alert';
}
</script>
</body>
</html>
It is faster and easier to use Katex rather than Mathjax for math formula rendering in Html.
For reference(Comparison between katex and latex ) :
https://www.intmath.com/cg5/katex-mathjax-comparison.php
So the solution by using katex will be :
<!DOCTYPE html>

<form action="#">

<input type="button" value="save" onclick="onSubmit()">

<div id="show" id='ed2'></div>
<script>
CKEDITOR.replace('editor1', {

if (CKEDITOR.env.ie && CKEDITOR.env.version == 8) {
document.getElementById('ie8-warning').className = 'tip alert';

function domChanged() {

Good luck !!!

I'm testing ckeditor.
I'm trying to create a ckeditor which fits the "div" where it's placed.
This is what I've tried, but only works on startup and not with resize window.
Is there an easy way to fit ckeditor the div where it's places?
Thanks

I am diving in the deep end of this magic world of HTML. I have the CKEditor woring and myFunction produces the alert. I need to get the HTML of the text in the editor.
I got this from another post:
CKEDITOR.instances.textarea.on( 'instanceReady', function( instanceReadyEventObj )
{
var editorInstanceData = CKEDITOR.instances.textarea.getData();
alert( editorInstanceData );
});
I could not comment or reply to the post as I don't have enough points so I have to ask a duplicate.
I have the alert working and pasted the code in myFunction but I get the error in the console Uncaught TypeError: Cannot call method 'on' of undefined.
<!DOCTYPE html>

<head>
<script>
function myFunction()
{
var htmldata = CKEDITOR.instances.Editor.document.getBody().getHtml();
alert(htmldata);
}

I've tried moving into different place but I still get the same error.

MrWarby.
Before your SCRIPT in HEAD add two more lines:
<script type="text/javaScript" src="http://ajax.googleapis.com/ajax/libs/jquery/1.10.1/jquery.min.js"></script>
<script src="/ckeditor/ckeditor.js"></script>
But change path to CkEditor script.
I tried to write an AJAX-type form with Twitter Bootstrap, but the updated div element disappears. Can I fix that?
<!DOCTYPE html>
<html>
<head><link href="bootstrap.min.css" rel="stylesheet" media="screen"></head>
<script>
function wordCloud(){document.getElementById("cloud").innerHTML = "WordCloud";}
</script>
<body>
<script src="http://code.jquery.com/jquery-latest.js"></script>
<script src="bootstrap.min.js"></script>
<div id="cloud"></div>
<form onsubmit="wordCloud()">
<fieldset>
<button type="submit" class="btn">Submit</button>
</fieldset>
</form></body>
</html>
Change as follows.
function wordCloud(){document.getElementById("cloud").innerHTML = "WordCloud";}
replace
function wordCloud(){document.getElementById("cloud").innerHTML = "WordCloud"; return false; }
and
<form onsubmit="wordCloud()">
replace
<form onsubmit="return wordCloud()">
I was testing out this demo on query-ui-maps:

The demo works in safari on my desktop but loads the screen attached whether I test in an ios5 simulator or an ios5 phone. No errors are logged to the console. I am testing in Xcode and using phone gap.
Please help.
This is the code:
var mobileDemo = { 'center': '57.7973333,12.0502107', 'zoom': 10 };
$('#directions_map').live('pageinit', function() {
demo.add('directions_map', function() {
$('#map_canvas_1').gmap({'center': mobileDemo.center, 'zoom': mobileDemo.zoom, 'disableDefaultUI':true, 'callback': function() {
var self = this;
self.set('getCurrentPosition', function() {
self.refresh();
self.getCurrentPosition( function(position, status) {
if ( status === 'OK' ) {
var latlng = new google.maps.LatLng(position.coords.latitude, position.coords.longitude)
self.get('map').panTo(latlng);
self.search({ 'location': latlng }, function(results, status) {
if ( status === 'OK' ) {
$('#from').val(results[0].formatted_address);
}
});
} else {
alert('Unable to get current position');
}
});
});
$('#submit').click(function() {
self.displayDirections({ 'origin': $('#from').val(), 'destination': $('#to').val(), 'travelMode': google.maps.DirectionsTravelMode.DRIVING }, { 'panel': document.getElementById('directions')}, function(response, status) {
( status === 'OK' ) ? $('#results').show() : $('#results').hide();
});
return false;
});
}});
}).load('directions_map');
});
$('#directions_map').live('pageshow', function() {
demo.add('directions_map', $('#map_canvas_1').gmap('get', 'getCurrentPosition')).load('directions_map');
});

After much searching, this has proved to be the best answer:

<script type="text/javascript">
$(document).ready(function ()
{
$('.date').datepicker

<div>
Date: <input type="text" id="datepicker"/>
</div>
<div>
#Html.TextBox("toDate", Model.toDate.ToString("dd/MM/yyyy"), new { #class = "date" })
</div>
The above is cshtml page.. I am clueless why the date that i click on the datepicker wont show up on the texbox/input .. Can you help?

What is this mess? What are you asking? In your question you didn't show how your code look like so we can only be guessing here. Normally when you ask a question you should show precisely how your code looks.
So here's a guess I can make to improve your code with a working example:
View:
#model AppName.Models.SomeViewModel
<script src="#Url.Content("~/Scripts/jquery-ui.min.js")" type="text/javascript"></script>
<script src="#Url.Content("~/Scripts/jquery.validate.min.js")" type="text/javascript"></script>
<script src="#Url.Content("~/Scripts/jquery.validate.unobtrusive.min.js")" type="text/javascript"></script>
<script type="text/javascript">
$(function () {
$('.date').datepicker({
showStatus: true,
highlightWeek: true,
showAnim: 'scale',
firstDay: 6,
showOptions: {
origin: [ 'top', 'left' ]
},
onSelect: function () {
}
});
$('#datepicker').datepicker();
});
</script>
<div>
Date: <input type="text" id="datepicker"/>
</div>
<div>
#Html.TextBox(
"toDate",
Model.toDate.ToString("dd/MM/yyyy"),
new { #class = "date" }
)
</div>
