• Javascript: Taking the highest 2 numerical values out of a series of 4 possible values.

  - by Bodhi

  What I'm trying to do is to take the highest two values out of 4 possible variables and add them together, while ignoring the lesser two values. My values will be anywhere between 1 and 5. So, for example, if I have Trait1, Trait2, Trait3 and Trait4 with the following assigned values: 3, 3, 2, 1, the script will pick up the 3 and the 3, but not the 2 and the 1. If I change the values around so that I have 4, 3, 1, 5, the script will pick up the 4 and the 5, but not the 3 and the 1. How would I go about doing this? Thank you in advance.

• Is it possible to use os.walk over SSH?

  - by LeoB

  I'm new to Python so forgive me if this is basic, I've searched but can't find an answer. I'm trying to convert a Perl script into Python (3.x) which connects to a remote server and copies the files in a given directory to the local machine. Integrity of the transfer is paramount and there are several steps built-in to ensure a complete and accurate transfer. The first step is to get a complete listing of the files to be passed to rsync. The Perl script has the following lines to accomplish this: @dir_list = `ssh user@host 'find $remote_dir -type f -exec /bin/dirname {} \\;'`; @file_list = `ssh user@host 'find $remote_dir -type f -exec /bin/basename {} \\;'`; The two lists are then joined to create $full_list. Rather than open two separate ssh instances I'd like to open one and use os.walk to get the information using: for remdirname, remdirnames, remfilesnames in os.walk(remotedir): for remfilename in remfilesnames: remfulllist.append(os.path.join(remdirname, remfilename)) Thank you for any help you can provide.

• Multible jquery .load() methods not running concurrently in MVC 2

  - by Boob

  In one of my aspx pages i have something like this in the head: <script type="text/javascript"> $(function() { // Jquery stuff loadStuff(); }); function loadStuff() { $('#result1').load({ source: url }); $('#result2').load({ source: url }); $('#result3').load({ source: url }); }; </script> The idea being that as the page is being displayed these loads will populate the specified divs with results from different webservices as and when the info becomes available. My problem is that this requests are being queued and being sent one at a time. However I want these to be sent at the same time and whichever returns first gets displayed first! Also if I try to kick off another request while these divs are loading the request seems to get queued after the others. How do I make these requests concurrent instead of queued? Thanks

• thoughts on making a widget?

  - by Haroldo

  I'm only going to be able to get each site that wants my widget, to copy and paste the code block in once.. So it needs to be really future proof. I've thought about this for a while and this is the widget code i've come up with : <script type="text/javascript" src="http://www.mydomain.com/my-future-proof-widget.js"></script> <div id="mywidget"></div> would this be the best plan? could this create any limitations? any other thoughts on widgetry?!

• Reason for unintuitive UnboundLocalError behaviour 2

  - by Jonathan

  Following up on Reason for unintuitive UnboundLocalError behaviour (I will assume you've read it). Consider the following Python script: def f(): # a+=1 # 1 aa=a aa+=1 # b+='b' # 2 bb=b bb+='b' c[0]+='c' # 3 c.append('c') cc=c cc.append('c') # 4 a=1 b='b' c=['c'] f() print a print b print c The result of the script is: 1 b ['cc', 'c', 'c'] The commented out lines (marked 1,2) are lines that would through an UnboundLocalError and the SO question I referenced explains why. However, the line marked 3 works! By default, lists are copied by reference in Python, therefore it's understandable that c changes when cc changes. But why should Python allow c to change in the first place, if it didn't allow changes to a and b directly from the method's scope? I don't see how the fact that by default lists are copied by reference in Python should make this design decision inconsistent. What am I missing folks?

  The title explains it well. I have set up Notepad++ to open the python script in the command prompt when I press F8 but all Swedish characters looks messed up when opening in CMD but perfectly fine in e.g IDLE. This simple example code: #!/usr/bin/env python #-*- coding: UTF-8 -*- print "åäö" Looks like this. As you can see the output of the bath file I use to open Python in cmd below shows the characthers correctly but not the python script above it. How do i fic this?

• Shell scripting and test expressions

  - by Paul

  Hi, I'm trying to test whether a directory path exists when a file is passed to my script. I use dirname to strip and save the path. I want my script to run only if the path exists. This is my attempt below. FILE=$1 DIRNAME=dirname $FILE if [ -z $DIRNAME ] ; then echo "Error no file path" exit 1 fi But this doesn't work. Actual when there is no file path dirname $FILE still returns "." to DIRNAME, i.e. this directory. So how do i distinguish between "." and "/bla/bla/bla". Thanks.

• Regex: How to leave out webding font characters?

  - by DS

  Hi, I've a free text field on my form where the users can type in anything. Some users are pasting text into this field from Word documents with some weird characters that I don't want to go in my DB. (e.g. webding font characters) I'm trying to get a regular expression that would give me only the alphanum and the punctuation characters. But when I try the following, the output is still all the characters. How can I leave them out? <html><body><script type="text/javascript">var str="???????";document.write(str.replace(/[^a-zA-Z 0-9 [:punct]]+/g, " "));</script></body></html>

• Using PHP to determine if a remote file has been replaced?

  - by Rob

  I have a MySQL database with some URLs in it. One URL per row. Each URL has my script on it. What I am wanting to do, is check if the file is still there via a PHP script. Not check if it 404'd, but rather check if it has been modified or replaced. Is this possible? If so, how would it be accomplished? I was thinking making the remote file echo some string, and having the local file check the page for that string, but that seems a little inefficient and sloppy.

• How do I implement jQuery image cycle loops on rollover for multiple thumbnail sets on a page?

  - by Kendrick Ledet

  Here is the Javascript I currently have <script type="text/javascript"> $(function() { $('.slideshow').hover( function() { $('.slides').cycle('resume'); }, function() { $('.slides').cycle('pause'); } ); $('.slides').cycle({ fx: 'fade', speed: .3, timeout: 280, next: '#next', prev: '#prev' }).cycle("pause"); }); </script> It works; but the thing is it works for all thumbnail sets on the page, and whenever I mouseover on one set of images, every other set of images loops as well. I do see that this is because I'm targeting classes, but my jQuery experience is quite limited so I have no idea how to only target a single instance of each class without effecting the others, and I can't go in and hardcode id's because my thumbnails and amount of videos on each page are determined dynamically via this Django template. http://pastebin.com/nf42bSAx I would greatly appreciate any help, as this is essential for my project (open source media platform). Thank you.

• Ajax response seems to be getting lost

  - by Ringo Blancke

  I'm using the ddslick jquery dropdown plugin in conjunction with my Rails app. In view1, I have $('#challenges_dropdown').ddslick({ <snipped> onSelected: function (data) { $.ajax({ url: "/load_data", type: "GET", data: {"id": data.selectedData.value} }); } }); I.e., I make a call to my controller to load_data. The controller receives this correctly and then at the end, makes a call to render a separate view render "data" This view contains a script snippet that needs to run in order to update some elements of my original view. For some reason, this script snippet is just not running. I'm very confused. When I use a regular link with data-remote="true", then the whole process works perfectly. However, when I make an AJAX call, it fails. What's going on?? Thanks! Ringo

• list all functions on CRAN

  - by baptiste

  Suppose I'm trying to run a script of unknown origin, and one of the functions is from a package that is not loaded by the script (an oversight, maybe it was loaded in the .Rprofile of the person who wrote it). How can I find in which package this function resides? There's some information compiled on CRAN, that doesn't require the user to download/install all R packages locally; however as far as I could tell it only gives access to the DESCRIPTION files. RSiteSearch, and its web equivalent, seem to access an online database of all CRAN packages, where presumably a list of all functions would be available. Is there some way of accessing this information? Thanks. Edit: I know sos::findFn, utils::RSiteSearch and search.r-project; what I would like is to get the raw data that these tools use.

• ActionScript: Using 'in' on protected/private variables?

  Is there any way to mimic the in operator, but testing for the existence of protected or private fields? For example, this: <mx:Script><![CDATA[ public var pub:Boolean = true; protected var prot:Boolean = true; private var priv:Boolean = true; ]]></mx:Script> <mx:creationComplete><![CDATA[ for each (var prop in ["pub", "prot", "priv", "bad"]) trace(prop + ":", prop in this); ]]></mx:creationComplete> Will trace: pub: true prot: false priv: false bad: false When I want to see: pub: true prot: true priv: true bad: false

• JQuery, Load() contents with plugins

  - by Galas

  I know this is not a completely new question, but none of the answers solved my problem... I have built a little menu that uses load() to load image galleries (as external html files) into a specified div ("content"). The said galleries make use of a JQuery plugin (SlideJS). Now I know that load() does not work for script tags and that I need to use $.getscript in the callback function in order to run the scripts, but it does not work. I have two .js files that need to be loaded: one is the plugin itself and another one is a smaller script with a preloader and the animations for the captions. I can't seem to merge them together; if I put them into the same document, the script won't run. So I tried just using $.getscript to load the two files. I tried using two callbacks as suggested in other answer (I know it's not ideal...): $("#proposal").click(function(){ $(this).addClass('selected'); $("a:not(:#proposal)").removeClass('selected'); $("#content").load("works/proposal/proposal.html", function(){ $.getScript("js/slide.js", function (){ $.getScript("js/slidepage.js"); }); }); }); and I tried a variable (read about it in some other faq, not sure if the syntax is correct) $("#proposal").click(function(){ $(this).addClass('selected'); $("a:not(:#proposal)").removeClass('selected'); $("#content").load("works/proposal/proposal.html", function(){ var scripts = ['js/slide.js','js/slidepage.js']; $.getScript(scripts); }); }); So none of these work. What am I doing wrong? I'm just starting on jquery and my js knowledge is very limited. Should I just merge the two .js files together using minify or something? One of them is already minified, but I've tried with a non-minified version and it does not work either. Can anyone suggest any other solution around this problem? I thought of just having the div embedded in the main document and just showing it on click, but I'll have at least 4 galleries with about 8 to 10 images each... its a lot of images to load in the main page, so I don't think its the best way. if you need me to post any more code, please ask! Thanks in advance for all your help!
