[jQuery] Re: AJAX and transforming proxies
Tom Hume wrote on 12/17/2008 8:38 AM: If the header was respected, would you consider it an appropriate mechanism to avoid problems with these proxies? I believe that's the entire purpose of no-transform, to instruct the proxies to not transform the data: http://www.freesoft.org/CIE/RFC/2068/169.htm If so I guess I'm wondering whether it'd be prudent to start asking AJAX library authors to include it. AJAX library authors only have control over the request -- that is, requests from the client to the server. Are there transforming proxies that mess with requests? More likely they're only transforming responses from the server, in which case it's up to the server to add the header, not the AJAX library authors. To have Apache automatically add the no-transform cache directive header, you'd do this (must have mod_headers enabled): Header set Cache-Control no-transform I personally do this: # # CONFIGURE media caching # Header unset ETag FileETag None FilesMatch (?i)^.*\.(ico|flv|jpg|jpeg|png|gif|js|css)$ Header unset Last-Modified Header set Expires Fri, 21 Dec 2012 00:00:00 GMT Header set Cache-Control public no-transform /FilesMatch # # That will cause the browser to cache all media (including CSS and JavaScript) until 2012, and includes the no-transform directive. - Bil

Paul Hammant wrote on 11/23/2008 7:28 AM:
The article talks of prepending with {d: and suffixing with } if the

The best strategy is to generate a unique token (nonce) when you create a
session for the user and store that value in their session, then with every
request that you want to protect, include the nonce with the request. So it'd
look like:
$.get(path/to/my/service?nonce=s8NPYG1Nhsy3GI0yFKju ...)
Then on the server, confirm the nonce passed in matches the nonce stored in the
session before you return any data. Since an attacker won't know the nonce
value, it defeats the CSRF attempt.

Mike Alsup wrote on 11/21/2008 7:27 PM: Responses to this method are not cacheable, unless the response includes appropriate Cache-Control or Expires header fields. What are your response headers? Hmmm. I created a new demo that uses $.ajax and includes both GET and POST: http://www.corry.biz/cachetest/ For POST, Firefox 3 does send the following two headers: Pragma: no-cache Cache-Control: no-cache And you can't override it in FireFox with SetRequestHeader(). This is interesting because the XHR spec says the browser shouldn't auto-send those headers, and it should allow our script to override those values: - If the user agent implements a HTTP cache it should respect Cache-Control request headers set by the script (e.g., Cache-Control: no-cache bypasses the cache). It must not send Cache-Control or Pragma request headers automatically unless the user explicitly requests such behavior (e.g., by (force-)reloading the page). http://www.w3.org/TR/XMLHttpRequest/#send - Beyond that, my server ignores those request headers and sends new data every time the browser asks for it. And as you can see in the cache tests, Firefox refuses to cache a POST, even when it receives headers directing it to cache the page contents (the same headers work successfully with GET). In contrast, Internet Explorer 7 by default caches everything unless you tell it not to with response headers (or a random URL token). It behaves identically for both GET and POST. - Bil

In the absence of cache headers from the server, browsers can choose the behavior they want, and FF chooses to not cache the page, and IE chooses to cache the page. You can see the behavior of your own browser here: http://www.corry.biz/iecache/ You'll see four buttons, clicking each one multiple times will perform multiple AJAX calls. You can tell if the request is being cached if the returned time displed doesn't change.

[jQuery] Re: Cross domain with $.ajax(url : 'http://someWhereElse.aspx')
John Ruffin wrote on 11/12/2008 11:59 PM:
Bil, can you elaborate on your approach a bit? Short example.
Sure, you mentioned you were trying to do this:
$.ajax( url : 'https://somedomain.com/secure/somefile.aspx')
Instead, you have to do this (assuming your site is mydomain.com):
$.ajax( url : 'https://mydomain.com/remotecall.aspx')
That will load a page off of your server, but you want it from the remote
server. So remotecall.aspx on your server then has to perform the request, get
the result, and return it to the browser. In other words, remotecall.aspx on
your server is acting as a proxy to the remote server.
I'd give you some example code for ASP.NET, but I don't program in it. Here's
what it would look like in the server-side language I do use, which is Lasso:
content_body =
include_url('https://somedomain.com/secure/somefile.aspx',
-postParams=client_postParams, -getParams=client_getParams,
-SendMIMEHeaders=client_headers);
What it's doing is setting the response to the browser being the response from
the remote server, and it's proxying the GET, POST, and request headers to the
remote server. That's a simple example, in the real world, if you use HTTP
Authentication or Cookies, or pass the session ID via a GET/POST param, then
you'll want to filter out those headers/params before sending it on to the
remote site to avoid leaking sensitive data.
The other tricky bit is if you're relying on the browser to already be logged
into the remote site (either via a session cookie or HTTP Authentication) --
the user's browser will not send your site the cookie or Auth headers needed to
authenticate to the remote server. In that case, the user will have to provide
you with their username and password for the remote site in order for your
server to masquerade as them. If you control the remote server, then you can
code around this limitation.

What do I do, just put a load of anchor tags at the bottom to all the

not for the user.
One solution would be to wrap the anchors on the page in noscript so bots and
those not using JavaScript can find the content.
Another would be to use CSS to { display: none } the anchors so that the
anchors are still viewable to bots, but not to browsers.
Another would be to by default show anchors and not your content, then use
javascript to hide the anchors and show the content.
Another would be to use Sitemaps and list the Sitemap in your robots.txt file:

character. If the final page is in UTF-8, then any illegal character will be
transformed into a special UTF-8 character. You will not be able to reverse it
in that case as you could have dozens of illegal characters and they're all now

The only reason to do what Google is doing (using the Last-Modified header) would be if the resource could changed at any given moment. But the AJAX libraries are all versioned and will never change (there would be a new version). So that can't be it. Which leaves us with only one other reason (that I can think of) which is the Last-Modified header allows Google to track the visitors using your site on every page that uses the jQuery library. - Bil

[jQuery] Re: removing html comments from the dom
James wrote on 8/18/2008 10:04 AM: Does anyone know if it is possible to remove html comments from the DOM with jQuery? My problem is that I really need a page to render in full standards- compliance mode in IE, but my outdated corporate CMS (Vignette) inserts an html comment at the beginning of every page which throws IE into quirks mode rendering. (Ordinarily this is not a major problem, I just code with the appropriate CSS hacks to accomodate quirks mode). In this instance though, it's causing some very jerky show/hide animations which only become smooth in standards compliance mode. If IE is in quirks mode, can you reset it to standards mode by adjusting the DOM? Another option is to place a proxy between your CMS and the internet and use the proxy to strip off the HTML comment. - Bil
[jQuery] Re: Packed version 32 kB
hosemaria wrote on 7/22/2008 12:45 PM: My tests says that packed version is the slowest one up to 3-4 times. Why is that? Resig explains it here: - When distributing a piece of JavaScript code it's traditional to think that the smallest (byte-size) code will download and load the fastest. This is not true - and is a fascinating result of this survey. Looking at the speed of loading jQuery in three forms: normal, minified (using Yahoo Min), and packed (using Packer). By order of file size, packed is the smallest, then minifed, then normal. However, the packed version has an overhead: It must be uncompressed, on the client-side, using a JavaScript decompression algorithm. This unpacking has a tangible cost in load time. This means, in the end, that using a minifed version of the code is much faster than the packed one - even though its file size is quite larger. http://ejohn.org/blog/library-loading-speed/ - What is the reason to use packed version? At JQuery main site they say Packed version is Great for production use. You should use the minified version. The only scenario I can think of to use the packed version is where the connection speed is so slow, the smaller size more than makes up for the lag in decompressing the packed version. - Bil
[jQuery] Re: Firefox 3 and packed jQuery
hubbs wrote on 7/21/2008 11:23 AM: What exactly is the difference between minified and packed? Minified is the JavaScript condensed; same code, just smaller in size (it removes extra white space, comments, etc). Packed is the JavaScript compressed; it also includes a bit of JavaScript code to uncompress it. The best solution is serving jQuery minified and have the web server gzip (compress) it for those browsers that support it. Even if your web server doesn't support gzip compression, the minified version is still the better pick according to Resig: - This means, in the end, that using a minifed version of the code is much faster than the packed one - even though its file size is quite larger. http://ejohn.org/blog/library-loading-speed/ - Given the above, I'm not sure when or why you'd ever use the packed version. - Bil

If that is possible, won't the stateless issue be resolved since I can use global variables on the main page to store autorization, activity, state, etc.? It seems this would be an exact fit to my current programming process. It also would not require a framework since my app is essentially the total framework. You could code a webapp like this, where it's driven from a master page on the client side. The issue is if the client is responsible for storing authorization, state, etc, then a malicious user could circumvent your authorization and change their state. That's why the proliferation of server-side frameworks; they provide the scaffolding you need to build a secure web app (a way to maintain the state of the client, a way to authorize them, etc). The #1 rule for secure webapp programming is to treat all client input (headers and request) as hostile until proven otherwise (or sanitized). - Bil

[jQuery] Re: Convert special characters
hubbs wrote on 5/22/2008 12:23 PM: Karl, it seems to be the biggest problem when text is copied from MS Word, then sent through ajax. The quotes don't play nice. The curly quotes from MS Word are in the Windows-1252 character set. You're using ISO-8859-1, which does not have the curly quotes (they don't exist in ISO-8859-1). So even if you work around the UTF-8 issue, you will never get the curly quotes to work properly in ISO-8859-1 (except maybe browsers that auto-detect the charset mismatch and adjust accordingly). So at a minimum, you should change to Windows-1252 character set if you want to support the extended MS characters, but if you're going to switch, just jump to UTF-8 and call it good. - Bil

[jQuery] Re: Turn off Cache Busting in $.getScript
Karl Rudd wrote on 5/14/2008 5:28 PM: The ajaxSetup() options affect all subsequent calls. The random cache busting value should no longer be appended. Thank you for the clarification. Firefox and Internet Explorer will obey the cache headers sent by the server for the requested content (assuming the user hasn't changed the default cache settings of the browser). It's only in the absence of a cache header that FireFox and Internet Explorer behave differently. Firefox defaults to not caching the request whereas Internet Explorer defaults to caching the request. So in practice, the random cache busting value really only benefits Internet Explorer when used against a server that doesn't explicitly tell the browser whether to cache the request or not. I'm not sure how Safari and Opera behave, I haven't tested those browsers. I think it might be worthwhile to document that the cache option really is just a way to have jQuery force the page to not be cached when set to false, overriding the request cache header. But when set to true, it defers to the cache header, or if none present, if defers to the default browser behavior. So this is the important point -- setting the cache option to true does not mean the request is cached, it just means jQuery won't force the page to be not cached. Whether the request is cached or not depends on the cache header, or when none present, the default browser behavior. - Bil

I played with it a bit. It appears the anonymous functions being bound to mousseover and mouseout don't have
access to the functions outside themselves when the page is first being loaded (perhaps they're not fully
bound yet?). Below is a simple test case, load it in Firefox, pop open Firebugs, place the cursor over the
Test Span, hit Ctrl-R to reload the page and rapidly move the cursor in/out of the Test
Span. If you do, you'll see the error xyzzy is not defined when the page is first loading,
then the error goes away once those anonymous functions have access to functions outside themselves.
And the problem occurs regardless of the placement of JavaScript on the page; it
still happens when all the JavaScript is in the head as well. One
work-around is to surround all the code contained within the anonymous functions with
try/catch, and simply ignore the errors.

[jQuery] Spolsky's Strategy Letter VI
This is interesting in the context of jQuery's core optimization vs. larger, less-optimized libraries: - The developers who put a lot of effort into optimizing things and making them tight and fast will wake up to discover that effort was, more or less, wasted, or, at the very least, you could say that it “conferred no long term competitive advantage,” if you’re the kind of person who talks like an economist. http://www.joelonsoftware.com/items/2007/09/18.html - - Bil

Didn't get any answers so last night I wrote it myself. Sorry, I must have missed your post (I find it difficult to keep up with the traffic on this list). This is what I've been using for many years, the only tweak I made to it was to make it case-insensitive: http://www.codeproject.com/jscript/tablefilter.asp - Bil

[jQuery] Re: Fwd: jQuery and UTF8
barophobia wrote on 8/15/2007 11:15 PM: Content-Typetext/html Does that give you a clue? Your server should be sending this as the content-type if serving UTF-8: text/html; charset=UTF-8 Otherwise, you're leaving it up to the browser to decipher the charset. - Bil
[jQuery] Re: Fwd: jQuery and UTF8
barophobia wrote on 8/20/2007 11:58 AM: 1. Why do you think the standard pages work fine? Do you have a meta tag defining the charset? Most likely that wouldn't be present in an AJAX call but would tell the browser the correct charset. 2. What about the issue I'm having sending the data? How do I get the UTF-8 text to be recorded properly when submitted via an AJAX call? I believe jQuery sends the data as UTF-8; the issue as I understand it is when you want to send something other than UTF-8, as per this thread: http://groups.google.com/group/jquery-en/browse_thread/thread/5fc0bd4e73d41e03/#anchor_94c6c9cd173ae26d You said you're using Japanese characters, are you sure you're using UTF-8 or could you be using SHIFT_JIS? Do you have an example page? - Bil
[jQuery] Re: Create excel file from table data
Glen Lipka wrote on 8/10/2007 10:34 AM: Yes. Specifically a table. You can even add CSS backgrounds, and borders which Excel picks up too. (Assuming the headers say its excel) And you can tell Excel how to format the data, for example to display a US zip code: td style=font-align: right; color: red; mso-number-format:0;07643/td Or a date: td style=font-align: right; color: red; mso-number-format:-mm-dd;2006-12-20/td The other option that has been offered on the LassoTalk list is creating an Excel file that has the format you want, save it as XML, then replace the dummy placeholder text with the real values. The downside to the XML method is XML is only supported by newer versions of Excel (not sure how new Excel has to be). - Bil

[jQuery] Re: Frequently Asked Questions (FAQ)
Richard D. Worth wrote on 7/14/2007 8:06 AM: Just a few to start with. Please add any questions you've seen come up a lot. Two questions I had when starting with jQuery, and glancing through the API docs, I still don't see them documented (maybe in a tutorial?): (1) How do you select an element by its ID? (2) How do you select all elements given a CSS class? Seems like they should be included on the Selectors page. - Bil
[jQuery] Safari 3 and onload
Via Ajaxian, interesting browser behavior: - Safari does not fire onload at the same time as other browsers. With most browsers, they will wait until the page is loaded, all images and stylesheets and scripts have run, and the page has been displayed before they fire onload. Safari does not. In Safari, it seems onload fires before the page has been displayed, before layout has been calculated, before any costly reflows have taken place. It fires before images have completed loading (this can also happen in rare cases in Opera, but Safari seems to do it everywhere), meaning that a substantial part of the load time is not included. http://www.howtocreate.co.uk/safaribenchmarks.html - - Bil

[jQuery] Re: Safari for Windows Support Questions
Glen Lipka wrote on 6/13/2007 9:53 AM: - Why couldn't Apple just support Firefox? It works fine! KILL SAFARI! This came up on the Lasso list. Not sure how true it is, but John Gruber claims Safari currently earns Apple about $2 million per month, and would generate much much more with Windows users also using Safari: It’s not widely publicized, but those integrated search bars in web browser toolbars are revenue generators. When you do a Google search from Safari’s toolbar, Google pays Apple a portion of the ad revenue from the resulting page.
