Currently I use $('div#edit').froalaEditor('html.get') to retrieve the html data inside editor, but it sucks when it comes to process / store the text data in my backend because of all the p tags and &npsb; symbols in raw html string.
To be honest they do not even pass to the database without losing parts of the data. Is there a way or an api to directly extract the text data as a string with proper symbols like "\n\t" from the froala editor?
If you dont like p tags you should use the enter option:
$('div#froala-editor-br').froalaEditor({
enter: $.FroalaEditor.ENTER_BR
});
If you really would like to remove all tags you could use jQuery text method
jQuery($('div#edit').froalaEditor('html.get')).text()
Or you could use HTML options
var html = $('div#edit').froalaEditor('html.get') ;
var div = document.createElement("div");
div.innerHTML = html;
alert(div.innerText);
There is http://textversionjs.com/ library which can be used to convert HTML to plain text. It also keeps new lines.
<script src="textversion.js"></script>
<script>
var html = $('div#edit').froalaEditor('html.get');
var text = createTextVersion(html);
</script>
Honestly, the easiest way to do this is
var body = $('#body').froalaEditor('html.get');
alert($(body).text());
You can use stringify() method in JSON to convert the HTML form to a text form.
<script>
var html = $('div#edit').froalaEditor('html.get');
var text = JSON.stringify(html)
</script>
And you can store them in any backend and use them later.

Given a html, I'd like to get first 100 characters of text (content without the markups)
I could create a jquery object with the html and use .text().
But the problem is that browsers may load all the images in the html.
So I wonder if there's a way to extract text snippet from html without building a DOM.
edit
given a html (just a string of html, not part of DOM yet)
<p>my lord</p><img src="some_url"><br>I'm overloaded
I could do $('<div/>').append(html).text().substr(0, 5); to get 5 characters.
But the img is downloaded by browser, and I don't want that.
var s = "<p>my lord</p><img src=\"some_url\"><br>I'm overloaded"
s = s.replace(/<[^>]+>/g,'').substr(0, 100);
You could remove the image elements and then load it to the dom
Something like
var html = "<p>my lord</p><img src="some_url"><br>I'm overloaded";
html = html.replace(/<img[^>]*>/g,"");
var firstFive = $('<div/>').append(html).text().substr(0, 5);
I am not sure how practical this question is , but what i am trying to do is find html inside a string and then append pre tags to it using jquery. let say i have a variable with following string.
var string = "Some normal text <html><body><div> This is the html </div> </body></html>";
Html inside the string is dynamic and can contain any tags , what i want is to find the starting and ending of html and append,prepend pre tags accordingly.
Thanks
The following code does pretty much what you want, however it does not allow html, body tags etc. But those are not allowed in pre tags anyway.
var string = "Some normal text <html><body><div> This is the html </div> </body></html> more text<p>more html content</p>";
var holder = $('<div>').html(string);
holder.children().wrap('<pre>');
//Print result to console
console.log(holder.html());
Also a jsFiddle here: http://jsfiddle.net/evBCm/1/
Add the text to dynamic html tag e.g span or div and find desired node e.g
var string = "Some normal text <html><body><div> This is the html </div> </body></html>";
$("<span/>").html(string).find('div')
Apply bellow regix..
var string = "Some normal text <html><body><div> This is the html </div> </body></html>";
var iMatches = string.match("<html>(.*)</html>");
var iHtml='<html>'+iMatches[1]+'</html>';
alert(iHtml);
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
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.
I'm trying to convert HTML to plain text. Is it efficient? Am I missing something?
txt = $("body").find("script,noscript,style,:hidden").remove().end().text();
Thanks!
HTML is text.
EDIT Try this...
// Get current body text
var html = $("body").text();
// Create a new jQuery object out of body text and remove desired elements
var text = $(html).remove("script,noscript,style,:hidden").text();
You want element.textContent (element.innerText for IE).
var scriptContents = $('body').find('script').html();
var noScriptContents = $('body').find('noscript').html();
var styleContents = $('body').find('style').html();
If you're trying to just render it to the screen you might be able to:
<pre>
some html here
</pre>
