Resize EpicEditor based on the content put within it

I'm using epiceditor within my site, and I am populating it with markdown embedded on the page by the server. Currently when epiceditor displays, it has a very small default height, with scroll bars to handle viewing the entire content. I can manually set the height of the div, and for now that's the best I've been able to do (I've set it to something reasonably large: 800px). However I would like its height to always be enough to fit the entire content without scroll-bars. Essentially something like overflow:visible.

Here's the relevant portions so far

<html>
    <head>
        <script src="/assets/javascripts/epiceditor/js/epiceditor.min.js"       type="text/javascript"></script>

        <script id="postMarkdown" type="text/markdown" data-postId="1">
            #Markdowns in here
            ...
        </script>
        <style>
            #epiceditor{
                height: 800px;
            }
        </style>
        <script src="/assets/javascripts/thrown/posts/edit.js" type="text/javascript"></script>
    </head>
    <body>
        <div id="epiceditor">
        </div>
    </body>
</html>

And heres the edit.js source (its compiled from coffescript)

$ ->
    postMarkdown = $("#postMarkdown").first()

    options =
        basePath : '../../assets/javascripts/epiceditor'
    editor = new EpicEditor(options).load()
    postId = postMarkdown.data('postId')
    markdown = postMarkdown.html()
    editor.importFile('posts/'+postId,markdown);
    editor.reflow();

I was hoping reflow might expand the height after the content was inserted, however no such luck. However If I resize the div and call reflow, It does resize properly. I've inspected the markup it creates in hopes I could determine the height and resize its container and tell it to reflow. However it seems it contains multiple iframes, and at a glance I didn't expect that to be a quick change, or if it would even be possible. However I'd welcome any solution.

I also understand that if I size its container to the right height, epiceditor will fill the proper space. However I want its height to be the amount needed to render, such that the editor takes up the right space in the rest of the sites design. Therefore if there something I can set in EpicEditor to have it not overflow in the manner it is, or a way to determine the height after it loads, I'm set. Thanks for any help.

Solution

  • I'm the guy who made EpicEditor, here's a solution for you:

    var editor = new EpicEditor({
  basePath: 'https://raw.github.com/OscarGodson/EpicEditor/develop/epiceditor'
});

var updateEditorHeight = function () {
  editorHeight = $(editor.getElement('editor').body).height();
  // +20 for padding
  $('#epiceditor').height(editorHeight + 20);
  editor.reflow();
}

editor.load(function (){
  updateEditorHeight();
});

editor.on('update', function () {
  // You should probably put a check here so it doesn't
  // run for every update, but just on update, AND if the
  // element's height is different then before.
  updateEditorHeight();
});

    Also, in the CSS I added a overflow: hidden to epiceditor's wrapper so the scrollbars don't appear as it grows.

    UPDATE

    As of EpicEditor 0.2.2 autogrow is built in. Just turn on the autogrow option.
