Inline Editing

Postby webPragmatist on Sun Oct 05, 2008 4:50 pm

I am trying to instead of create an iframe with a scolling area actually create an inline editor (so it looks like you are actually changing the content on the page.

I basically just need for the textarea/iframe to grow (in height) as more content is entered.

Any help will be appreciated. I tried removing the iframe and textarea hights but it still has some default height and still scrolls.

nicEdit supports this sort of thing http://www.nicedit.com/demos.php?demo=4

Looks like this is harder than it seems... About the only thing I found on resizing iframes to fit the parent page container is:

Which seems to be rather hackish... Is it possible to swap out the iframe element and make a div or some other element editable instead? That's what nicEdit seems to do.

While there is no way to bind an onChange event to an iFrame, you can sort of simulate it using setInterval().

Here is what I did, placing this code in the postInit function customization:

Code: Select all
// check the iFrame's height and resize it appropriately every 3 seconds...
var iframe = $(wym._box).find(".wym_iframe").find('iframe').get(0);
$(iframe).height(iframe.contentWindow.document.body.scrollHeight + 100);
var si_id = setInterval(function(){
  $(iframe).height(iframe.contentWindow.document.body.scrollHeight + 100);
},3000);


basically, what this does is change the actual height to that of the iFrame's scrollHeight every 3 seconds, works great in Firefox 3+. You can change the interval from 3 seconds to whatever by changing the 3000 to some other value, every 1000 is equivalent to 1 second.
