• Uncaught TypeError: Converting circular structure to JSON

  - by ychia

  We're using the fb:registration plugin to sign up users on our site. Today I noticed the registration redirect is no longer working in Google Chrome and Safari (latest public release). I know for sure it was working with the same code as recently as last week. It seems to be getting stuck on submission with this error, which is coming from: static.ak.fbcdn.net/rsrc.php/v1/ys/r/ioE9qOq_5Oa.js:101 Firefox and IE have no problem, so it seems to be Webkit specific. Any ideas?

• Authenticating mssql users through different logins

  - by Sebastian Ferreyra

  I'm developing a new node.js based frontend for an old intranet site using mssql server and Classic ASP. Both the new and the old site will coexist during the transition phase and both must access the same mssql server using the same database principals. The old ASP/IIS site uses integrated windows login. The new node-based frontend has to use sql server based logins/principals (edit: while the IIS/ASP site must keep using Windows server principals) and all existing database users/principals must keep working wherever they login from. From reading around, it appears that a database principal can not be assigned to multiple server principals, therefore it seems unlikely there's a simple solution to this. I'd like to know if anybody has had to deal with a similar situation before and how they've gone about it.

• Decent JavaScript IDE

  - by thatismatt

  What is a decent IDE for developing JavaScript, I'll be writing both client side stuff and writing for Rhino. Ideally It needs to run on Mac OSX, although something that runs on Windows too would be nice. ADDITIONAL: Having had a play with both js2 and Aptana, I think I'll be continuing to use Aptana. Mainly because I find emacs a bit hard to get my head round, although I did think that the error hi-lighting in js2 was better than that in Aptana. I'm still looking for a way to visually debug my js code that is running atop Rhino...

• Does Google Analytics have peformance overhead?

  - by Mohit Nanda

  To what extent does Google Analytics impact performance? I'm looking for the following: Benchmarks (including response times/pageload times et al) Links or results to similar benchmarks One (possible) method of testing Google Analytics (GA) on your site: Serve ga.js (the Google Analytics JavaScript file) from your own server. Update from Google Daily (test 1) and Weekly (test 2). I would be interested to see how this reduces the communication between the client webserver and the GA server. Has anyone conducted any of these tests? If so, can you provide your results? If not, does anyone have a better method for testing the performance hit (or lack thereof) for using GA?

• Lightweight PHP server to bundle with application?

  - by munchybunch

  Does there exist some sort of PHP server that can be bundled with a locally-deployed application? It sounds wonky, but the end result is I can't use a remote web server to do anything. Clients will be downloading a package, and the plan is to use a Java backend that reads from a flat file. The flat file contains settings and is modified through a GUI written in HTML/JS, and this is where the server would come in. The forms in HTML should be able to submit to the server, which does a simple file write to the flat file. Is there any simple, lightweight server that has that simple feature? When running the executable for the application, it would start the installation process for the server before moving the web GUI files to the appropriate locations. Note that I'm doing this for a client, so I can't quite change the reqs and would rather not discuss their effectiveness. I would be ever thankful if people had suggestions for the server though!

• jQuery Upload Progress Plugin Not working in Chrome and Safari

  - by Conceited Code

  I am using the jquery.uploadprogress plugin to get the upload progress of a file from the NginxHttpUploadProgressModule. This is inside an iframe for a facebook application. It works in firefox, but it fails in chrome/safari. When I open the console I get this. Uncaught ReferenceError: progressFrame is not defined jquery.uploadprogress.js:80 Any idea how I would fix that? I would like to also send the file using AJAX when it is completed. How would I implement that? EDIT: I need this soon and it is important so I am going to put a 100 point bounty on this question. The first person to answer it will receive the 100 points. EDIT 2: Jake33 helped me solve the first problem. First person to leave a response with how to send the file with ajax too will receive the 100 points.

• How do I start a XUL Runner application maximized?

  - by Anthony D

  I've started developing my first app with XUL and I've run into a problem that I can't seem to solve. All I want to do is have my app start maximized. I've set the sizemode attribute to maximized on my top level window element but that has no effect. My prefs.js file has the following line: pref("toolkit.defaultChromeFeatures", "chrome,centerscreen,menubar,resizable,status,toolbar,scrollbars"); This also does not work. My window appears and it only has a close button (X) and does not have a minimize or maximize button. Any ideas???

• Finding matches between multiple JavaScript Arrays

  - by Chris Barr

  I have multiple arrays with string values and I want to compare them and only keep the matching results that are identical between ALL of them. Given this example code: var arr1 = ['apple', 'orange', 'banana', 'pear', 'fish', 'pancake', 'taco', 'pizza']; var arr2 = ['taco', 'fish', 'apple', 'pizza']; var arr3 = ['banana', 'pizza', 'fish', 'apple']; I would like to to produce the following array that contains matches from all given arrays: ['apple', 'fish', 'pizza'] I know I can combine all the arrays with var newArr = arr1.concat(arr2, arr3); but that just give me an array with everything, plus the duplicates. Can this be done easily without needing the overhead of libraries such as underscore.js? (Great, and now i'm hungry too!) EDIT I suppose I should mention that there could be an unknown amount of arrays, I was just using 3 as an example.

• Storing DOM reference elements in Javascript array

  - by webzide

  Dear experts, I was trying to dynamically generate DOM elements using JS. I read from Douglas Crockford's book that DOM is very very poorly structured. Anyways, I would like to create a number of DIVISION elements and store the reference into an array so it could be accessed later. Here's the code for(i=0;i<3;i++){ var div=document.body.appendChild(document.createElement("div")); var arr=new Array(); arr.push(div); } Somehow this would not work..... There is only 1 div element created. When I use the arr.length to test the code there is only 1 element in the array. Is there another way to accomplish this. THanks in advance

• What's the best way to offer javascript embed that won't slow a page down?

  - by Shpigford

  I have a chunk of javascript that users can copy and paste to put on their sites. I'm currently using the following code (ala WEDJE) that allows the rest of the page to load even if my script is slow or not responding. <script type="text/javascript"> var number = "987654321"; var key = "123abc"; (function(){ document.write('<div id="ttp"></div>'); s=document.createElement('script'); s.type="text/javascript"; s.src="http://example.com/javascripts/embed.js?" + Math.random(); setTimeout("document.getElementById('ttp').appendChild(s);",1); })() </script> But that method is a few years old and so I wasn't sure if there was a more efficient way of doing the same thing that others have come up with.

• automatic push to CDN deployment strategy

  - by imanc

  Does anyone have ideas for a strategy to push content to a CDN upon deployment? The key issue I'm facing is that we have a site that is available in various contexts: local development, development server, staging, then finally live. The liver version of the site needs to load assets from a domain, which will be pointed to a CDN: assets.domain.com. However, we will have numerous references to the assets pointing to a relative folder, e.g. /images/ in css, possibly in js, and in HTML & source. Our new site will use capistrano for deployment and it may be that we can hook in another build tool (apache ant?) or some custom script to search / replace paths. I am wondering if anyone has had to deal with this issue before and what solutions you put in place to automate managing the CDN in terms of pushing content up to the CDN and managing html & css references to assets in the CDN. Thanks Imanc

• System.Web.HttpException in asp.net mvc 2 on images and javascript files

  - by Rippo

  Hi I am getting the following errors reported by ELMAH on my asp.net mvc 2 site for javascript files, images etc. System.Web.HttpException: The remote host closed the connection I have done some research and it appears that the user/bot is clicking a link on the site before the page has fully loaded. Now this error never occurs on a controller action but always on a file that is on disk. e.g. /Content/CmsImages/logo.png /Content/CmsImages/MemberImages/Photo-001605.jpg /Content/jquery.tickertype.js So this means that all static files are being routed through the mvc pipeline. What options do I have?

  Hi! I wrote this post Music and Mathematics, finding the Natural and the Pentatonic scales. Is a method to find the Natural scale. I want to discuss it and find if its true. This is the code of the reasoning in js. <script> var c = 12/7; var tot = 0; var scale = []; while(tot < (14 - c)){ tot += c; scale.push(Math.round(tot)); } if(scale.length == 8){ document.write(scale + " " + c + "<br />"); } </script>

• [grails] attaching multiple files to a domain class

  - by Emyr

  I've seen various Grails plugins which allow easier handling of file uploads, however these tend only to support a single file per form-submit. I'd like a multi-attach form where as soon as you pick one file, an extra field and button is added using JS (various sites do it like this). Do you know of any good plugins which provide elegant uploading of multiple files without excessive coding? A progress bar either per-file of for the whole process would also be very nice. I don't know to what extent I can allow GORM to handle a java.io.File field (or in this case a Collection<File>).

• Google Analytics to track FireFox extension use

  - by Swizec Teller

  Hi all, I'm developing a Firefox extension and would like to track its use with google analytics, but I can't get it working. I've tried manually calling a funstion from ga.js, but that didn't work for some reason. No error was produced, but neither was any data collected. My last attempt was to have a website that just holds the tracking javascript and then loading it within the extension in an iframe with the URL configured so it contains meaningful data. This way the analytics are getting connected when I visit said webpage with a browser, but not in an extension. I've tried putting some visible javascript ont he site and have confirmed the site's javascript is executing. This method also works with other trackers, but I don't like their output and would prefer Google Analytics. Any ideas what else I could try to accomplish this?

• jquery onclick function not firing with rails link_to_remote

  - by RahTha

  In the js file of the page, inside $(document).ready(function() {} i have $(".school a").live("click", function (e){ e.preventDefault(); ....; jsFunc(param1, param2, param3); }); Now the div with the class school has tags generated by rails link_to_remote with :url, :action, :before, :html. On clicking on this link it does all that it should do with regards to link_to_remote, but somehow the onclick event in the document.ready does not attach to it. Why would this be happening? The jsFunc all it does is post to a url async-ly, i figured out that stuffing that post url in the :before of the link_to_remote would work - but is there a more elegant way of just being able to use the attach functionality

• make javascript repeat for each row in a view

  - by Kathy Chavez

  I have created a view in Drupal. I"m using javascript to modify css in each row. The script runs on the first row, but does not make the changes on the rest of rows from the view. This is the script: <script language="javascript" type="text/javascript"> window.onload = floatbr; function floatbr() { var f = document.getElementById('firstright') // Get div element var s = document.getElementById('secondright') // Get div element var w = document.getElementById('catwrapper') // Get div element var sh = s.offsetHeight // secondright div height var wh = w.offsetHeight // catwrapper div height f.style.height = wh - sh + 'px'; } </script> I'm using it from this page: http://agsone.100webcustomers.com/floatbottom.php having the script in the page once does not do the trick. having the script in the view footer and repeating the script does not work. THanks! link to fiddle with html, css & js: http://jsfiddle.net/Vvjku/
