You should check by putting alerts in your script section line by line and see, where you code is breaking. Also, your xmhttp variable is not declared. It should be declared somewhere as var xmlhttp;

Answer 2

HTML is the markup for the textual content on information superhighway content. It specifies such issues as what shade the historic past is, the position the photos are, no matter if certain textual content is ambitious or italic etc. CSS is a way of creating better certain criteria that may then be separated from the HTML textual content and dictate the creation of dissimilar distinct information superhighway content, as an party finer administration over fonts, heading sizes etc. Javascript is a scripting language which permits uncomplicated applications like video games and calculators to be written for use on the information superhighway website - no longer to be at a loss for words with Java, it extremely is a desirable programming language yet is likewise used on information superhighway content.

Answer 3

You have a syntax error. I won't tell you what it is: check your browser's error log.



(@Prem's suggestion, of using alert() in various places is a good one, but it can only locate logic errors, not syntax errors.)



(BTW, nowadays people would write this code easily using libraries like jQuery, as in http://pastebin.com/b4gcnJPm , but it's fine that you learn to do it the hard way first.)
