• How to write a program that mimics Fiddler by using tcpdump or from scratch?

  - by ????

  When Fiddler is not on Mac OS X or Ubuntu, and if we don't install/use Wireshark or any other more heavy duty tools, what is a way to use tcpdump so that 1) It can print out GET /foo/bar HTTP/1.1 [request content in RAW text] [response content in RAW text] POST /foo/... HTTP/1.1 this should be able to be done by tcpdump or by using tcpdump in a short shell script or Ruby / Python / Perl script. 2) Actually, it can be neat if a script can output HTML, with GET /foo/bar HTTP/1.1 POST /foo/... HTTP/1.1 on the page, for any browser to display, and then when clicked on any of those lines, it will expand to show the RAW content like (1) above does. Click again and it will hide the details. The expansion UI can be done using jQuery or any JS library. The script may be short... possibly less than 20 lines? Does anybody know how to do it either for (1) or (2)?

• Why call iframe from javascript

  - by sammville

  I want to know why some ad codes or embed codes don't directly give you iframe code to embed on your site instead they give a javascript code which links to another javascript file on their server. The file on their server calls the iframe which serves the content. Why is this done and what are the benefits of this method. Example: this is the code issued by amazon: <script type="text/javascript" src="http://www.assoc-amazon.co.uk/s/ads.js"></script> Which opens another javascript file that calls the iframe.

• Are AJAX calls to a sub-domain considered Cross Site Scripting?

  - by AaronPresley

  I have Server A (www.example.com) sending information to Server B. I can only have HTML / JS on Server A (and have to do the "crunching" on Server B) so I'm trying to send form data via AJAX (trying to avoid a form post to Server B - don't ask). Obviously doing an AJAX call cross-domain is considered XSS and a big no-no, but if I were to put Server B in a subdomain (sub.example.com), would that be considered okay? How are cross-domain errors detected? Does the browser look up DNS records? IP address? Thanks in advance for you help.

• Communicating between an overlayed iFrame and the underlying page (LAMP)

  - by stef

  I have a small form is to be filled in. If the user is logged in, the form is submitted as normal. If the user is not logged in, I show an overlayer with an iframe'd page that contains a login box where he enters his credentials. If the credentials are correct I can "break out" of the frame to "return" to the main page, but how can I update this main page for example to show "you are now logged in" and to change the JS / PHP login that determines whether or not the form can be submitted normally and not be intercepted again by the overlayer prompt? Afaik, these two separate pages are not aware of each other so I'm struggling to find a solution to this problem. This is in a LAMP / jQuery / CodeIgniter environment. EDIT: Could CodeIgniter's XML RPC class be useful for this?

• What makes a web site 'finished' for delivery to a client?

  - by AP257

  Hi, Sorry if this question has already been answered, and sorry if it's too subjective to make sense, or for StackOverflow. I'm delivering a site to a client and I want to send them high-quality HTML/CSS/JS, fully validated, accessible etc. So I'm compiling a list of things to check, and useful tools for doing so, before I hand the code over. Here's a partial list, but what am I missing? Link checking for any broken links I might have missed - W3C link checker HTML validation for accessibility and broken-ness - W3C HTML validator CSS validation - W3C CSS validator Check for slow-loading page elements - Firebug and YSlow plugin What's missing - if you were a client, what else would you want to be sure has been checked? I'm wondering about the etiquette of things like comments, indentation, and minification; is it good practice to sort out all these? And what else have I missed? Thanks :)

• Project hosting on Google Code. Files are cached?

  - by Frexuz

  I do not really understand how Google Code handles file versioning. I am building a jQuery plugin that anyone can access. Like so: <script type="text/javascript" src="http://jquery-old-browser-warning.googlecode.com/files/jquery.browser-warning.js"></script> This script accesses other files on the same project (via ajax). The problem is, that when I upload a new file, it just seems like there aren't any changed to it. Google recommends that new files should have new names. But then I would have to change the filenames that the script loads. But then I would have to change the script file as well, and that would break everybodys implementation (with the script-tag above) Is there a way to force a file to change when uploading with the same filename? PS: If I go directly to the project page's file list. Then I do get the file with the updated content. But as I said, not when getting it through ajax.

• Virtual Tour Viewer?

  - by Jessica

  My client wanted me to put a virtual tour video on their website. They bought it from "ForRent.com". They forwarded it to me, and its nothing but the panoramic images. When I asked about some type of viewer/player, they simply stated I would need js or flash installed on my computer (i do). Of course, thats not going to magically put these photos into a virtual tour. This is my first time working with a virtual tour, so does anyone know of any viewers I could just put the images into so that the user could click and drag?

• Rails 3: jQuery form not working.

  - by donald

  Hi, I have jquery working on my Rails app using the gem 'jquery-rails'. I also have a search form working correctly. However, when I add :remote => true the form stops working. <%= form_tag services_path, :method => :get, :remote => true do %> <%= text_field_tag :search, params[:search] %> <%= submit_tag "Search", :name => nil %> </div> <% end %> I have also added a index.js.erb but it has no effect on it. For some reason the :remote = true makes the form to stop working. Any reason why? Thanks

• CSS file not getting downloaded in Visual Studio 2008 SP?

  - by theraneman

  Hi guys, This might sound a little wierd, but all of a sudden the CSS and Javascript files referenced in my master page are not being downloaded while the page is being rendered. I am working on a ASP.NET MVC project and things were all fine like half an hour ago! Here is what I have in head section of the master page, <link href="/Content/MyCSS.css" rel="stylesheet" type="text/css" /> <script src="/Scripts/jquery-1.3.2.min.js" type="text/javascript"></script> I can see the CSS class intellisense while designing pages. But in the page source I do not see these files being added. I can see the css being applied in the VS designer. I have tried restarting VS, restarting my machine too. Anyone else faced this situation before. I might go crazy now.

• In QT 4.6 w/ Webkit: How to handle popup window requests (WebView::createWindow)?

  - by CM

  Hi all, I'm new to QT and have been trying to create a test browser. What I'm trying to do now is to handle js-based popup requests. After reading the QT documentation, I learned that I need to re-implement the QWebView::createWindow method to do just that. Now I've re-implemented this method, but it seems to be not called when I try to click a link that triggers a popup window. Can any one help me? Do I need to subclass both the WebView and WebPage classes? If so, how do I do that? I'm quite new to QT and I've done tons of searches and found nothing. Thank you all in advance for any hint and advice!

• How to make a div float in and scroll with the center of page?

  - by Murvinlai

  So, I work on a Facebook FBML App. What I want is simple. Just have a div shows in the center of the page, and scroll with the page. i.e. always in the center. It would be easy with normal JS. I just use the pageYOffset However, in Facebook using FBJS, I am not sure what I should use. It doesn't have getPageYOffset().. and I tried getScrollTop().. it doesn't seem the right thing. So, anyone knows how?

• Marking "example usage" in code documentation

  - by Ross

  What the best practice of placing example usage in code documentation? Is there a standardised way? With an @usage or @notes? For example: /** * My Function * @param object id anObject * @usage a code example here... */ function foo(id) { } or /** * My Function * @param object id anObject * @notes a code example here, maybe? */ function foo(id) { } I know this question should dependent on the documentation generator, but any heads up appreciated... I'm trying to get into the habit of using proper style. When time allow I'll get more into the generators. (I've experimented with Doxygen.) I often use AS3, JS, Obj-C, C++. Thanks

• How do I submit a form from another page?

  - by Tommy

  I have a two page site. Each page contains a header with "tabs" at the top, to navigate between page 1 and 2. When a tab is selected, I need the selected page to re-POST to the server, to quickly refresh before it is displayed. I have a form on each page that allows a manual refresh from that page but need to submit that form from the other page. For example, page 2 is displayed. The tab for page 1 is selected (which is on page 2) It should then submit the refresh form on page 1. Any help is appreciated. (Using jQuery, js, html and CSS)

• Client validate non-model bound checkbox while using MVC 2 jQuery Validation

  - by Justin Saraceno

  Have: Using ASP.NET MVC 2, DataAnnotationsModel based server validation, and client validation with jQuery. Anything in my model is validated perfectly on the client with jQuery based validation (jQuery.validate and MicrosoftMvcJQueryValidation.js). Need: Adding an additional HTML <input type="checkbox" id="terms" /> to my form. I need jQuery validation to require that this checkbox is checked AND somehow hook it in with whatever jQuery client script MVC is automagically controlling. Yes, I know it won't validate on the server side, but I don't need or want it to. Seems like it should be simple but I'm new to MVC, a total beginner at jQuery, and my searches have been coming up blank. Any help would be appreciated!

• How to prevent robots from automatically filling up a form?

  - by sombe

  I'm trying to come up with a good enough anti-spamming mechanism to prevent automatically generated input. I've read that techniques like captcha, 1+1=? stuff work well, but they also present an extra step impeding the free quick use of the application. (I'm not looking for anything like that please). I've tried setting some hidden fields in all of my forms, with display: none; However, I'm almost certain a robot (which is essentially a program) can be configured to trace that form field id and simply not fill it. Do you implement/know of a good anti automatic-form-filling-robots method? Is there something that can be done seamlessly with HTML AND/OR server side processing, and be (almost) foolproof? (and please no JS, one could simply disable it, and there goes my anti-spam method). Btw I'm trying not to rely on sessions for this (like, counting how many times a button is clicked to prevent overloads).

• compromised site

  - by pinniger

  So, I have a web site that has been compromised twice in two weeks. every index.php and .js file gets a script injecting into the source code of the file. The problem is that I have no idea how they're doing it. I've seen this done via sql injection before, but I don't know how they are actually writing to the file. I've dug through the Apache logs but didn't find anything interesting. The site is built using the cakephp framework on a godaddy shared server. Anybody know what secturity settings or log files to check to see how they are doing this?

• running code when two events have triggered

  - by Evert

  This is mostly a language-agnostic question. If I'm waiting for two events to complete (say, two IO events or http requests), what is the best pattern to deal with this. One thing I can think of is the following (pseudo js example). request1.onComplete = function() { req1Completed = true; eventsCompleted(); } request2.onComplete = function() { req2Completed = true; eventsCompleted(); } eventsCompleted = function() { if (!req1Completed || !req2Completed) return; // do stuff } Is this the most effective pattern, or are there more elegant ways to solve this issue?

• jQuery slideDown() not animating (jquery-rails 3.0.4; jquery-ui-rails (4.0.5)

  - by Michael Guren

  I am following along in the latest Agile Web Development with Rails 4 book. In Chapter 11 (AJAX), the book instructs us to use the following code in the "create.js.erb" file: if ($('#cart tr').length == 1) { $('#cart').show('blind', 1000); } This code causes the #cart div to jump down without any content. After 1 second it appears. There is no sliding effect. I tried using slideDown(); as well, but the div just appears immediately. Out of curiosity, I tried slideUp(); when the div was visible. Voila. The div slid up. This appears to be a jQuery bug and wondered if anyone else has experienced this, or has any suggestions for me. Thanks.

• Get Flickr Sets

  - by PaulAdamDavis

  Hi everyone. Usual stuff, Googled forever, looked on here, no help. Yet. What I want is to list the sets of photos I have on Flickr. Nice & simple, it would seem. I want the 'title image' (the one used as the thumb for it on Flickr its self), the title and URL. Can't be that hard, can it? The language of choice is PHP (5.1.6), or JS (jQuery if possible). Both are good.

• Why repeat database constraints in models?

  - by BWelfel

  In a CakePHP application, for unique constraints that are accounted for in the database, what is the benefit of having the same validation checks in the model? I understand the benefit of having JS validation, but I believe this model validation makes an extra trip to the DB. I am 100% sure that certain validations are made in the DB so the model validation would simply be redundant. The only benefit I see is the app recognizing the mistake and adjusting the view for the user accordingly (repopulating the fields and showing error message on the appropriate field; bettering the ux) but this could be achieved if there was a constraint naming convention and so the app could understand what the problem was with the save (existing method to do this now?)

• Preventing a security breach

  - by Wiz

  I am creating a website where you "post", and the form content is saved in a MySql database, and upon loading the page, is retrieved, similar to facebook. I construct all the posts and insert raw html into a template. The thing is, as I was testing, I noticed that I could write javascript or other HTML into the form and submit it, and upon reloading, the html or JS would treated as source code, not a post. I figured that some simple encoding would do the trick, but using is not working. Is there an efficient way to prevent this type of security hole?
