Hi, I''ve got some code that takes what a user writes in a text area, and puts it into an html tag on the page. I want to display line breaks as they are entered, but I don''t want to use white-space:pre, and white-space:pre-line doesn''t seem to be supported (or isn''t what I thought it was). So I came up with this: DOMElement.innerHTML=text.escapeHTML().replace(/\n/g,"<br/>"); This works in FireFox, but in IE the escapeHTML function destroys all the carriage returns from the original text, so the replace always does nothing. Does anyone know how to either: - do what I want to do by another (sensible) means, - fix the code above, or - fix the prototype escapeHTML function, so that it doesn''t remove line breaks?

Maybe switch the order of operations? DOMElement.innerHTML = text.replace(/\n/g,"<br/>").escapeHTML(); ...or would that be worse? Just a thought.

What about
DOMElement.innerHTML = text.replace(/\n/g,
"[br]").escapeHTML().replace("/\[b\]/g",
"<br/>");

oops, small typo ;)
it should be:
DOMElement.innerHTML text.replace(/\n/g,
"[br]").escapeHTML().replace("/\[br\]/g",
"<br/>");

But it does an extra needless replace operation, and isn''t robust (replaces text that might be wanted). Here''s what I''m using now: text.replace(/&/g,"&").replace(/</g,"<").replace(/>/g,">").replace(/\n/g,"<br/>"); I have a feeling I can get away with only replacing one set of angle brackets, like this: text.replace(/&/g,"&").replace(/</g,"<").replace(/\n/g,"<br/>"); This is presumably the normal way that people without prototype escape their html, and I don''t like it much. I''d be much happier if IE didn''t destroy newlines in the prototype .escapeHTML function. If anyone can come up with a fix/workaround for that, I''d be interested.

Be sure to use $(DOMElement).update(blah) instead of DOMElement.innerHTML = blah Prototype has built-in workarounds for issues with IE and table-based elements, and there might be other stuff in the future. With .update() you can feel a bit safer here.
