how to remove bug character in html using jquery

I have a bug in my code and i try to remove it using jquery.
Some code:
<div id="content">
s
<div class="breadcrumb">
<h1>Test and etc</h1> etc etc....
I want to use jquery to remove the s (if exist...in some cases not)
I've tried
var cont = $('#content').html();
$('#content').html(cont.replace('/s\s(.*)/','$1'));
Seams that the code above is not working...some sugestions ?

Don't use a regex to remove a textnode by running a replace on the HTML, target the textnode directly
var content = document.getElementById('content'),
child = content.firstChild;
if (child.nodeType === 3) { // if textNode
content.removeChild(child);
}
FIDDLE

You do need to call the code when the DOM is ready. And remove the quotes.
$(document).ready(function(){
var cont = $('#content').html();
$('#content').html(cont.replace(/s\s(.*)/,'$1'));
});

I don't understand, why won't you remove it directly from the HTML source?
Is the code automatically generated (aka you didn't manually write that 's' there)? Because if it is, I strongly suggest you correct the bug itself. What you're trying to do is covering up a bug, not fixing it. It's good practice to get to the source of a bug and fix it.
Alas, if you really want to do this: You need to specify when your script is called. Most likely, you want it put into the $(document).ready() event.
$(document).ready(function(){
var cont = $('#content').html();
$('#content').html(cont.replace('/s\s(.*)/','$1'));
});

Grabbing text from a span tag

I have some code for Javascript using jQuery, and I've been wondering how to fix an element of it.
var dataGiven = +$("span.cost-in-usd:first-child").text();
However, the span tag is:
<span class="cost-in-usd" data-se="product-usd-value">42</span>
Is there a way of modifying my code in order for it to recognise data-se?

Yes, use data.
var datase = $('.cost-in-usd').data('se');
Some links;
http://api.jquery.com/jquery.data/
Here's a jsfiddle

The following will return the value of attribute
$('.cost-in-usd').attr('data-se');

Moving links in jQuery, adding to string causes [object Object]

I'm trying to move a link around but when I try to include it within a string it doesn't work. If I remove the string it does though. Why is this happening and how do I fix it?
$(document).ready(function(){
var link = $('a');
//Remove the '<div>'s and it works...
$('div').after('<div>'+link+'</div>');
});
See pen for an example: http://cdpn.io/AKnsL
Thanks.
ED: I probably should of noted that this is a simplified version of what I am trying to do, I'm trying to rebuild a menu (don't ask why...) and I have each link assigned to a variable which is then added in place to a rather long string of divs and such, which is all then added in "after" another div. I only mention in case it changes the way this could be done, and I should mention I'm no JS pro :)
Thanks#2!

The issue is because a jQuery selector, such as $('a') returns an object, and appending a string and an object results in what you've seen.
If you want to move the link to a different element in the DOM, use append():
var link = $('a');
$('div').append(link);

$("a") is actually an object, not a string. If you use $("div").after(link), jQuery will work out that you actually want to append the DOM element.
The problem comes in when you do '<div>' + link + '</div>', where JavaScript is creating the string before jQuery gets involved. this is where [object Object] comes from - this is JavaScript's way of creating a sensible String value for an object. What's being evaluated is $("div").after("<div>[object Object]</div>");
You can get around this by first creating your new div, appending the a to that, then appending your new div to the original.
$(document).ready(function() {
var link = $("a"),
new_div = $("<div />").append(link);
$("div").after(new_div);
});

You could use:
$('div').after('<div/>',{html:link});

Try:
div.innerHTML=""+$('a').attr("href").toString()+"";
or:
var str="";
str+=""+$('a').attr("href").toString()+""; // str will contain links href in it
That will append text to div as a string with its href as text to be appended.

javascript: extracting text from html

I am getting html content as below:
var test='<div id="test">Raj</div>';
How can i retrieve value Raj from above html content using javascript.

It sounds like you're trying to extract the text "Raj" from that HTML snippet?
To get the browser's HTML parser to do your dirty work for you:
// create an empty div
var div = document.createElement("div");
// fill it with your HTML
div.innerHTML = test;
// find the element whose text you want
test = div.getElementById("test");
// extract the text (innerText for IE, textContent for everyone else)
test = test.innerText || test.textContent;
Or in jQuery:
test = $(test).text();

If you use jQuery (I cannot believe I just said that ;)) you can get at the content immediately you wrap it in $(test).html
Someone else will tell you how to get at the innerHTML using a selector since everybody here are jQuery gurus but me
Update: somebody just did while I was editing: javascript: extracting text from html - see comments or updates to that

var test = getElementById('test')
try that

How to get the content of a Tinymce textarea with JavaScript

i have an array of content then how we get content of Tinymce textarea in javascript

I solved it with code:
// Get the HTML contents of the currently active editor
tinyMCE.activeEditor.getContent();
// Get the raw contents of the currently active editor
tinyMCE.activeEditor.getContent({format : 'raw'});
// Get content of a specific editor:
tinyMCE.get('content id').getContent()
the activeEditor is current editor,but i use tinyMCE.get('editor1').getContent() can not get the value of my editor, hope it can help you
Tinymce API: http://www.tinymce.com/wiki.php/API3:method.tinymce.Editor.getContent

lets say your mce textarea instance is:
<textarea id="editor1" ....></textarea>
then you get the content as follows:
var content = tinyMCE.getContent('editor1');
if you mean you have multiple instances of mce editor on one page and you want to get content then try this approach:
var inst, contents = new Object();
for (inst in tinyMCE.editors) {
if (tinyMCE.editors[inst].getContent)
contents[inst] = tinyMCE.editors[inst].getContent();
}
the above code adds each editor content into an array

I had the same problem. I have solved using this code:
tinyMCE.get('editor1').getContent();
Source: spocke is the author

You may use:
tinymce.get(editorid).getContent();

In my case (v4.3.12), none of the above worked, so I did a workaround:
Html code:
<div id="wrapper">
<textarea id="editable_container" name="editable_container"></textarea>
</div>
JQuery code:
var iframe = $('#editable_container_ifr');
var editorContent = $('#tinymce[data-id="editable_container"]', iframe.contents()).html();
console.log(editorContent);
Where editable_container is my tinyMCE editor's placeholder textarea, the editable area's iframe id is generated from adding a _ifr postfix to the placeholder's id, and the content-editable container (which contains the formatted text), has an id tinymce with a data-id attribute of the placeholder's id.

Use the getContent() method from the TinyMCE API.
Let’s say you have initialized the editor on a textarea with id=”myTextarea”. First access the editor using that same id, then call getContent(). For example:
var myContent = tinymce.get('myTextarea').getContent();
Or, instead of accessing the editor by id, you can access the active editor:
var myContent = tinymce.activeEditor.getContent();
If want to get the TinyMCE content without the HTML tags, you can pass in a parameter to indicate that you want the result in plaintext. For example:
var myContent = tinymce.get('myTextarea').getContent({format: 'text'});
More info and examples here: https://www.tiny.cloud/blog/how-to-get-content-and-set-content-in-tinymce.

tinymce.get('editorId').setContent(response.data);

This work for me for version 4 (9.8):
var Content = tinyMCE.editors['Your_ID'].getContent();

tinymce.activeEditor.getContent();

For version 4.1.9, this is what worked for me:
$(function(){
$('button').click(() => {
const out3 = tinyMCE.get('bobt').getContent(); //*MUST* be an ID, not a class
alert(out3);
$('#out').html(out3);
});
});
<textarea id="bobt" class="tinymce"></textarea>
<div id="outx"><button>Get it</button></div>
<div id="out"></div>
Notes:
.get() requires an ID, not a class
tinymce.get() or tinyMCE.get() both work -- uppercasing the MCE does not matter

If you are more familiar with (and are using the jquery wrapper), you can also do this using this:
$('#editor1').tinymce().getContent();
Where (editor1) is your selector.
