Getting the value from a TinyMCE textarea

I have a news editor for my site with which I am using TinyMCE. What I would like to be able to do is have a button (outside of the TinyMCE editor itself) that I can click to scan the textarea for any images, then list those images as options to use for a thumbnail image for said news article.

For an idea of what I mean, please see this link here: https://docs.google.com/leaf?id=0B05m73kzudwPNzUwZjkyNmItYjZkMy00NTdlLTlkNDctOGRhYThjMzNjNTM5&hl=en_US

My problem is that document.getElementById('NewsArticle').value is not returning anything when there is text in the textarea

The other potential problem is t开发者_开发技巧hat whats shown in the textarea is not actual code, but images etc too so I wasn't sure it would even work in the first place, but since when the form is submitted the data[News][article] value is back into text, I thought there might be a chance.

If anyone knows how to get either the content or code for the tinyMCE textarea, or has a better solution, I'd be interested to hear

TinyMce has an api for accessing content from the editor.

This code will grab the html from the active editor:

// 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()

Use below syntax, which will remove unwanted character from your input textarea....

(((tinyMCE.get('YourTextAreaId').getContent()).replace(/(&nbsp;)*/g, "")).replace(/(<p>)*/g, "")).replace(/<(\/)?p[^>]*>/g, "");

Try

window.parent.tinymce.get('contentID').getContent();

For some reason, the stock-standard tinymce.get() call didn't work for me, so I tried this and it works. :)

var temp = tinymce.get('textAreaName').save();
console.log(temp);

OR

var temp =tinymce.get('textAreaName').getContent();
console.log(temp);

Probably you have something like

<form>
  <textarea id="myArea">Hello, World!</textarea>
</form>

you should simply add as follows

<form method="post">
  <textarea id="myArea" name="value">Hello, World!</textarea>
  <input type="submit">
</form>

and you can catch the data with PHP under myArea var.
