Issue #112  (designMode, CSS Tools, Content & Data, JS Utils)


(Skip to the tools section below)


There's a property called designMode on the document object that allows you to make an HTML document editable, the same way that an element can be editable using the contenteditable attribute.

Let's say we have the following HTML:
 
<iframe src="example.html" id="myFrame"></iframe>
<button>Get Frame Content</button>
<output></output>

The content of the iframe here doesn't matter for the purpose of this demo. We'll use the following JavaScript to dynamically add editing capabilities to the iframe:
 
var myFrame = document.getElementById('myFrame'),
    frameBody = myFrame.contentDocument.body,
    btn = document.querySelector('button'),
    op = document.querySelector('output');

frameBody.innerHTML = 'Click and edit the contents of this frame. Use ctrl-b and ctrl-i to add bold or italic.';

myFrame.contentDocument.designMode = 'on';
btn.addEventListener('click', function () {
  op.innerHTML = frameBody.innerHTML;
}, false);

Full demo is here

You might run into problems and differences in the 3 major browsers. Chrome is probably the best option for this example. Part of this is due to the fact that the iframe is using a non-existent source, which IE doesn't seem to like.

Nonetheless, as you can see, the designMode property can be set to either "on" or "off". I could also set the designMode to "on" for the current document, rather than the iframe. The above code allows the iframe to be fully editable by simply clicking inside it and typing some text. 

Note also in Chrome, if you use CTRL-B or CTRL-I, just like a rich text editor, the text will become bold or italic. Then, when you click the button to grab the frame content, it will appear on the current page with the formatting intact.

There's lots more I could write about this, as this does have quite a few quirks and browser differences. You can view the resources below for further info: Now on to this week's tools!
