For a web administration interface that we have developed here on Wohill we are currently using Ext JS for the AJAX functionality when saving and getting information from the database back and forth to the interface. We are using TinyMCE as the text editor when creating some kind of content to get a more desktop feeling.
When receiving information for a page which contains name, title, image, date and text, an asynchronous request is sent in the backround to get the data from the database. When the data has been queried from the database and we have a resultset, I am building a small JSON object with this information which is then sent back to the admin interface.
When receiving this information on the client (admin interface) side we need to decode the json object to be able to use all the pieces of information separately.
This workflow works fine in Firefox and Google Chrome but for Internet Explorer 7 (which is the only version of IE I have tested it on) it doesn't. The problem is when the text body (which is html) contains line break carrige return. Invincible characters in the string like '\r' and '\n' is what causes the error "Unterminated String Constant".
The JSON object that is built before sent to the client looks something like this:
var obj = Ext.decode(respStr); alert(obj.header); alert(obj.subHeader); // etc.
To make the fix for the error message in Internet Explorer; work with the response string a bit before decoding it and you will get rid of the error message. What happens is that all line break carrige returns are escaped:
var re = /\n/g; respStr = respStr.replace(re, '\\n'); re = /\r/g; respStr = respStr.replace(re, '\\r');
var obj = Ext.decode(respStr); alert(obj.header); alert(obj.subHeader); // etc.
Here is some more info on this problem. But in this case they had problem with IE 8 and not 7.

A cartoon dog
Sun, Aug 29th 2010 8:30p Randolph Guy I told you about our summer-guest #8211; Max - The American Cocker-Spaniel. He was a great wee friend and lots of fun. brbrI sat down here today after going to Toy Story 3 and sketched away on some work I have to get done. I then, as usual, got going on some drafts and some extra sketches. This time I was thinking of Max #8211; the dog - and thought it would be nice to draw a few lines that looked like a little dog-head.brbrNow I really have to get back to the stuff for tomorrow!brbrbr /br /img [read] Keywords:

More wild strawberries
Sat, Aug 28th 2010 8:29p Niklas Waller In the summertime when you are a kid in Sweden it is common to pick wild strawberries and put them on a straw. This is what all kids did when we visited my mother and uncle this summer.brbrI like the variation of sharpness in this photo. It goes from blurred to sharp and then back to blurred again in a nice way I think.brbrAnd wild strawberries really is summer to me!br /br /img src='http://www.wohill.com/images/wild_strawberries.jpg' /

A facial expression
Sun, Aug 22nd 2010 8:31p Randolph Guy An expression in a face shows a lot#8230; Or sometimes nothing#8230; brThe best is when you need to show as little as possible and yet it is totally clear what you are feeling.brbrThis design is a bit more of a thinking dude or expressive expression. It gives a feeling that you as the person meeting this face for the first time have to interpret what it is saying.

A great trip to Egypt
Sun, Aug 15th 2010 8:32p Randolph Guy Last Christmas we all where in Egypt. Really interesting trip I must say. I have written a few things about our trip before as you might have noticed. I also visited the Pyramids and the Egyptian Museum. There one could see lots of great designs and styles of design from ancient times. I must say that a lot of today#8217;s design can have been inspired by the old Egyptians.brbrHere I have mad a cartoon or tattoo-like #8221;Pharaoh#8221;.brbr /br /img src='http://www.wohill.com/images/Pharaoh_car [read] Keywords:

A female mallard duck
Sat, Aug 14th 2010 8:27p Niklas Waller In places where people live, Mallards are not very shy. They often come closer to see if there is something to eat. Therefore this isn't a rare photo in any way, but I always like getting them close since animals are beautiful. brbrThe male has a green head and is more colorful as males often are in the world of animals and the female is mostly brown. But she got some color on the back side at least.br /br /img src='http://www.wohill.com/images/mallard_duck_female.jpg' /
