Textpattern's hak_tinymce plugin does not work in IE

Question

I've set up Textpattern's hak_tinymce plugin on a website I run, and it works great in Firefox, Chrome, Safari and Opera. However, in IE the content area is gray (eg it just isn't there), and the Javascript fails with this error:

Webpage error details

Firebug gives no errors.

I am using a non-obfuscated version of tiny_mce.js, revision 1.158:

// Must have a src element in MSIE HTTPs breaks aswell as absoute URLs
if (tinyMCE.isMSIE)
    iframe.setAttribute("src", this.settings['default_document']);

iframe.style.width = tinyMCE.settings['area_width'];
iframe.style.height = tinyMCE.settings['area_height']; // ** THIS LINE! **

// MSIE 5.0 issue
if (tinyMCE.isMSIE)
    replace_element.outerHTML = iframe.outerHTML;
else
    replace_element.parentNode.replaceChild(iframe, replace_element);

I have no idea what this is. The only explanation I could find online, indicates that this is related to not using the www-prefix in the URL used to access the editor, but it does not seem to matter.

How do I solve this?

好吧，您可以尝试启用MS脚本调试器

Answer 2

The answer turned out to be a bug in hak_tinymce, not in tinyMCE itself. hak_tinymce specifies the height of the text area in a Javascript array using quotes around the value, like this:

somesetting: "somevalue",
height:"420",

When tinyMCE tries to do arithmetic on the height value, it somehow turns into a string, when it should have been treated as an integer. The script debugger revealed the height being set to "420-42", I did not figure out how.

However, in hak_tinymce, adding the following between line 276 and 277 works:

EOF;
$js = preg_replace('/height:\"(\d+)\"/i', 'height:$1', $js); // added line
return $js;

This fixes the problem both for the body and excerpt textareas.
