How to properly escape html sent as data in jQuery's .ajax function

Question

UPDATE: Once I looked at the problem in Firebug, I found my mistake immediately. And it was an embarrassing unmatched double quote that I must have deleted

Answer 1

You don't need to escape or encode. jQuery will take care of properly URL encoding the data:

data: { someHtml: $(this).html().substring(0, 1000) },
