Is there a way to determine which element submitted a form from within an onsubmit handler? Trying to write a generic handler that knows which element was clicked. For example, given this form: <form onsubmit="onSubmitHandler"> <input type="submit" name="submit1" /> <input type="submit" name="submit2" /> </form> How can I dete...
I have a forum page that displays a tree view of messages below the currently selected message. When you click on a message in the tree the new message body is loaded into a div near the top of the page using AJAX and then the following code is run: window.location.hash = "page_top"; Of course "page_top" is an anchor element near the ...
UPDATE: the HTML was not well formed. This was causing the script to appear in inner div. Please ignore the question. IE ver<8 has a known bug (Internet explorer cannot display the page. Operation aborted) If a script tries to append something to upper level block: The bug is described here: Update: I rephrased the question and simp...
This is mostly a rhetorical question, as far as I've checked the answer is 'don't even bother', but I wanted to be really sure. We have an email app, where you can send email to lists of subscribers. This is not spam: it's used, for example, by an university to send communications to its students, by a museum to send emails to subscribe...
Hi. I've got a JavaScript running 2 ".getElementById('').style" changes. Both work perfectly in FF, but the first one doesn't work in IE7. Appreciate all help :) First SourceCode: function ingen() { document.getElementById('merInfo1').style.display='none'; document.getElementById('merInfo2').style.display='none'; document....
I'm talking about the Ibox sort. I.e, user clicks a link and a small javascript based div hovers up containing a small form or such. I will want to give users a <script> tag which they would place in their website. Then, they would put the required javascript function in their <a href> tag which they want to use for displaying the form....
Is it possible to import css stylesheets into a html page using Javascript? If so, how can it be done? P.S the javascript will be hosted on my site, but I want users to be able to put in the <head> tag of their website, and it should be able to import a css file hosted on my server into the current web page. (both the css file and the j...
I want to have a javascript function such as this: function isUsernameAvailable(username) { //Code to do an AJAX request and return true/false if // the username given is available or not } How can this be accomplished using Jquery or Xajax? ...
So lately I've been catching a lot of crap from a junior developer whenever I use the term "dHTML". I know the term is dated, but it's descriptive of what the task is: changing rendered markup on the client. I cringe whenever i see the term Ajax applied to client side animation or form validation where no asynchronous request is being ma...
What the title says. How can it be done? I want them to click a hyperlink which, using javascript or any other methods, would redirect the parent window to a new url. ...
I'm having problems getting UI code to perform at all well in IE. I have a table - a matrix of values. Each cell can be empty or hold a list of items. I want users to be able to drag items between cells. So my HTML looks something like this: <table> <tr><td></td><th scope="col">col 1</th><th scope="col">col 2</th></tr> <tr><t...
I'm looking for a way to have a textbox that allows users to type in a date in any format and turns around and formats that date in a 'mm/dd/yyyy' format. So the user could type in "Today" and it would turn the date as 02/24/2009 or they could type in Wednesday Feb 24 and formatting would automatically pick up. Remember the Milk does t...
I have come to find that using jquery to create html client-side can be a huge performance booster if done properly. I use ajax returning json to retrieve dynamic content and then I build the relevant html and insert it using jquery. The first time I messed with this technique I found that the string concatenator in IE's javascript per...
So I have these checkboxes: <input type="checkbox" name="type" value="4" /> <input type="checkbox" name="type" value="3" /> <input type="checkbox" name="type" value="1" /> <input type="checkbox" name="type" value="5" /> And so on. There are about 6 of them and are hand-coded (i.e not fetched from a db) so they are likely to remain the...
I have a game on Google App Engine that's based on a 25x20 HTML table (the game board). Every 3 seconds the user can "move," which sends an AJAX request to the server, at which time the server rerenders the entire HTML table and sends it to the user. This was easy to write, but it wastes a lot of bandwidth. Are there any libraries, clie...
I wrote some Javascript to allow editing a list of items within an HTML form, including adding and removing items. Got it working in Firefox. When trying it in Internet Explorer, I found that any added items were not being submitted with the form. Long story short... lots of simplification, debugging, figured out what line is triggering...
In answering another question I became aware that my Javascript/DOM knowledge had become a bit out of date in that I am still using escape/unescape to encode the contents of URL components whereas it appears I should now be using encodeURIComponent/decodeURIComponent instead. What I want to know is what is wrong with escape/unescape ? T...
I want to get smarter in AJAX, but not sure which way to go. I have done some DHTML programming back in the day - like 8 years ago!, before it was called AJAX. I used emacs and hand-coded all the javascript, debugged via "Alert". At this point I think there are frameworks out there that make things nicer and easier, but which ones? ...

Hello, I am not a big web programmer, and have a friend who wants me to help him with something.
