  • Ruby methods within Javascript within HAML

    - by Josh
    I have a jQuery script that adds a new field to a form, and this field contains dynamic information from an array. The problem is that I can't figure out how to add an array.each to populate the options of the select field within the javascript without breaking the HAML indentation and causing errors. Here is my best attempt that does not work: %script(type="text/javascript") $('#mylink').click(function() { $('#mylink').after('<select> - myarray.each do |options| <option value="#{options.id}">#{options.name}</option> </select>); )}; Also tried it with the :javascript filter with no luck. EDIT: For whatever reason, I can't get the 4-space indents ( for Markdown ) working here, but I do have it indented properly.

  • jQuery Syntax Question, pretty easy I think..

    - by Fuego DeBassi
    Hi all, question: <script type="text/javascript"> $(document).ready(function() { $(".module .caption").hide(); $(".module").hover(function() { $(this).find(".caption").slideDown(); },function() { $(this).find(".caption").slideUp(); }); }); </script> This snippet works great for my purposes, the only caveat is that I need the .module hover function to simultaneously add a class of "under" to all other ".caption"'s that are not $this, and then remove them when the hover ends. So basically I don't want the "module" that is hovered to get the class, I want it to do exactly what I am showing here...sliding .caption up and down on end hover, I just want all other ".caption"s to get the under class when any ".module" is hovered. Just hitting a dead end with what I have been trying, want to do it in the same function. Any ideas?

  • Random password variable disappears

    - by snaken
    Hi, I'm using the following to generate a random password in a shell script: DBPASS=</dev/urandom tr -dc A-Za-z0-9| (head -c $1 > /dev/null 2>&1 || head -c 8) When i run this in a file on its own like this: #!/bin/sh DBPASS=</dev/urandom tr -dc A-Za-z0-9| (head -c $1 > /dev/null 2>&1 || head -c 8) echo $DBPASS A password is echoed. When i incorporate it into a larger script though the variable never seems to get created for some reason, so for example this doesn't work: DBPASS=</dev/urandom tr -dc A-Za-z0-9| (head -c $1 > /dev/null 2>&1 || head -c 8) sed -i s/oldpass/$DBPASS/ mysql_connect.php If i manually set the variable though everything is fine.. can anyone see why?

    - by user555222
    hi.. how can I position a div under another element without the rest of the layout is affected of the div element? <div style="margin:20px; padding:10px"> here is a little <span id="test" style="font-weight:bold">test</span> </div> <script> var elm = document.getElementById('test'); var div = elm.appendChild(document.createElement('div')); with(div){ style.position = 'absolute'; style.left = elm.offsetLeft; style.background = '#ffffff'; style.width = '100px'; style.height = '50px'; innerHTML = 'wooop'; } </script> this works in IE but not in FF.. FF ignores the style.left and position the element at 0px as if it was aligned to the left

  • How can I enable a debugging mode via a command-line switch for my Perl program?

    - by Michael Mao
    I am learning Perl in a "head-first" manner. I am absolutely a newbie in this language: I am trying to have a debug_mode switch from CLI which can be used to control how my script works, by switching certain subroutines "on and off". And below is what I've got so far: #!/usr/bin/perl -s -w # purpose : make subroutine execution optional, # which is depending on a CLI switch flag use strict; use warnings; use constant DEBUG_VERBOSE => "v"; use constant DEBUG_SUPPRESS_ERROR_MSGS => "s"; use constant DEBUG_IGNORE_VALIDATION => "i"; use constant DEBUG_SETPPING_COMPUTATION => "c"; our ($debug_mode); mainMethod(); sub mainMethod # () { if(!$debug_mode) { print "debug_mode is OFF\n"; } elsif($debug_mode) { print "debug_mode is ON\n"; } else { print "OMG!\n"; exit -1; } checkArgv(); printErrorMsg("Error_Code_123", "Parsing Error at..."); verbose(); } sub checkArgv #() { print ("Number of ARGV : ".(1 + $#ARGV)."\n"); } sub printErrorMsg # ($error_code, $error_msg, ..) { if(defined($debug_mode) && !($debug_mode =~ DEBUG_SUPPRESS_ERROR_MSGS)) { print "You can only see me if -debug_mode is NOT set". " to DEBUG_SUPPRESS_ERROR_MSGS\n"; die("terminated prematurely...\n") and exit -1; } } sub verbose # () { if(defined($debug_mode) && ($debug_mode =~ DEBUG_VERBOSE)) { print "Blah blah blah...\n"; } } So far as I can tell, at least it works...: the -debug_mode switch doesn't interfere with normal ARGV the following commandlines work: ./optional.pl ./optional.pl -debug_mode ./optional.pl -debug_mode=v ./optional.pl -debug_mode=s However, I am puzzled when multiple debug_modes are "mixed", such as: ./optional.pl -debug_mode=sv ./optional.pl -debug_mode=vs I don't understand why the above lines of code "magically works". I see both of the "DEBUG_VERBOS" and "DEBUG_SUPPRESS_ERROR_MSGS" apply to the script, which is fine in this case. However, if there are some "conflicting" debug modes, I am not sure how to set the "precedence of debug_modes"? Also, I am not certain if my approach is good enough to Perlists and I hope I am getting my feet in the right direction. One biggest problem is that I now put if statements inside most of my subroutines for controlling their behavior under different modes. Is this okay? Is there a more elegant way? I know there must be a debug module from CPAN or elsewhere, but I want a real minimal solution that doesn't depend on any other module than the "default". And I cannot have any control on the environment where this script will be executed...

  • Move document.ready function to a separate javascript fucntion?

    - by tonsils
    Hi, Is it possible to move the following code within a jQuery document.ready function into a separate javascript function, so that it can be called just like any other javascript function, i.e.: <script type="text/javascript"> $(document).ready(function() { $('div#infoi img[title]').qtip({ position: { adjust: { x:-110, y:0 }, corner: { target: 'bottomLeft', tooltip: 'topMiddle' } }, style: { width: 250, padding: 5, background: '#E7F1FA', color: 'black', textAlign: 'center', border: { width: 3, color: '#65a9d7' }, tip: 'topRight' } }); }); </script> If yes, then how - if not, then that answers my question. Thanks.

  • Standard procedure for confirming email for a web app

    - by Woho87
    Hi! I have created a web app that is almost finished. I need it to confirm new emails. I just want to know if the these are the right procedures for that, because I'm not familiar with this. I create a new table called "confirmEmails" with only one column with uniqueId. A unique Id is created with PHP: uniqueid() which is created directly after a user hit the submit button. And the php script stores it on the table. An email is sent together with a link www.domain.com/confirmEmail.php?uniqueId=kushfpuhrufhufhfhuhfheriufhehu. I have an another php script called confirmEmail.php that gets the value if uniqueId through the link with $_GET['uniqueId'];(maybe I shall use post instead her). And now it stores the new email in table called user Is it right procedures? Pls give me some feedback!

  • Preloading images in HTML, is there a more modern way?

    - by John
    I have an image loaded by JS on a mouse event. It's a fairly big image so I want to make sure it gets pre-loaded. I reemmber some old techniques from years ago and found this example: <SCRIPT LANGUAGE = JAVASCRIPT> if (document.images) { img1 = new Image(); img2 = new Image(); img1.src = "imageName1.gif"; img2.src = "imageName2.gif" } </SCRIPT> I wondered if this is still good/relevant, or maybe browsers automatically detect unused images and preload them anyway? Note my page has to support IE6, so I might still need older techniques anyway, but I'm still interested if more modern browsers have a better way?

  • T-SQL - Is there a (free) way to compare data in two tables?

    - by RPM1984
    Okay so i have table a and table b. (SQL Server 2008) Both tables have the exact same schema. For the purposes of this question, consider table a = my local dev table, table b = the live table. I need to create a SQL script (containing UPDATE/DELETE/INSERT statements) that will update table b to be the same as table a. This script will then be deployed to the live database. Any free tools out there that can do this, or better yet a way i can do it myself? I'm thinking i probably need to do some type of a join on all the fields in the tables, then generate dynamic sql based on that. Anyone have any ideas?

  • How to migrate Django models from mysql to sqlite (or between any two database systems)?

    - by Daphna Shezaf
    I have a Django deployment in production that uses MySQL. I would like to do further development with SQLite, so I would like to import my existing data to an SQLite database. I There is a shell script here to convert a general MySQL dump to SQLite, but it didn't work for me (apparently the general problem isn't easy). I figured doing this using the Django models must be much easier. How would you do this? Does anyone have any script to do this?

  • Minor tweak to this javascript function?

    - by RKS
    I have a script that shows/hides used via onClick. I can get it to show/hide just fine, but I can't get it to show/'hide everything else'. So what I get is a bunch of open containers when I really want just the one. Javascript: <script> function showfields(fields){ if(document.getElementById(fields).style.display=='none'){ document.getElementById(fields).style.display='block'; } else{ document.getElementById(fields).style.display = 'none'; } } </script> HTML: <div id="hidden" class="steps" style="display: block;"> <div class="section" style="margin-right: 10px;"> <h2>Something</h2> </div> <button class="continue dropdown" id="showLink" onClick="showfields('hidden2');return false;" href="#">Continue</button> </div> <div id="hidden2" class="steps" style="display: block;"> <div class="section" style="margin-right: 10px;"> <h2>Something2</h2> </div> <button class="continue dropdown" id="showLink" onClick="showfields('hidden3');return false;" href="#">Continue</button> </div> <div id="hidden3" class="steps" style="display: block;"> <div class="section" style="margin-right: 10px;"> <h2>Something3</h2> </div> <button class="continue dropdown" id="showLink" onClick="showfields('hidden3');return false;" href="#">Continue</button> </div> <div id="hidden4" class="steps" style="display: block;"> <div class="section" style="margin-right: 10px;"> <h2>Something4</h2> </div> <button class="continue dropdown" id="showLink" onClick="showfields('hidden4');return false;" href="#">Continue</button> </div> Thanks

  • imap_open dies when being called

    - by blauwblaatje
    Hi, I've got the following code: The script dies. I get zero responds, nothing from apache, no "foo" or "bar", nothing. I can however connect to the imap server (nc localhost ...), I can also put the script on another server and connect to the same imap server. So, I think there's something wrong with the php on this server. But I can't figure out what I'm missing, forgetting or didn't install. phpinfo() tells me php is configured --with-imap and --with-imap-ssl. The OS is CentOS, btw.

  • How to evaluate text strings provided by sed/grep/whatever?

    - by T.J.
    This is for UNIX shell programming. It have to be supported by multiple UNIX platforms including Solaris, Linux, and AIX. I have this scenario -- I am to read from a text file a string that may or may not contain an environment variable that may or may not be defined. For example: <foo.bar> This error code was found: $(error_code) I have the following code: statement=$(sed -n $1'p' $messagefile) echo $echo_flag $statement $1 = line number supplied to this particular function/script. $messagefile = filename of log file. $echo_flag = "-e" in Linux, otherwise, empty. $(error_code) = 42. Instead of getting this when running: <foo.bar> This error code was found: 42 I still get this: <foo.bar> This error code was found: $(error_code) How exactly do I tell the shell script that the value of statement should be evaluated further beyond what sed have done?

  • 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.

  • OSError: [Error 1] Operation not permitted

    - by user1357576
    I am trying to run a python script which uses a binary file (xFiles.bin.addr_patched) created by a postlinker. However, I am getting this error. File "abc.py", line 74, in ParseCmd shutil.copy(gOptions.inputX, gWorkingXFile) File "/usr/lib/python2.6/shutil.py", line 89, in copy copymode(src, dst) File "/usr/lib/python2.6/shutil.py", line 66, in copymode os.chmod(dst, mode) OSError: [Errno 1] Operation not permitted: 'myPath/xFiles.bin.addr_patched' When I checked the permissions of this xFiles.bin, by ls-l, it shows that -rwxrwxrwx 1 nobody nogroup I presume the error is because this file was created by some other application, the python script I am running does not have access to it. Since I am beginner wrt ubuntu, I don't really know how to fix it. Any suggestions on how to fix this? SOLVED: As one of the answers Suggested : chown username:groupname file name fixes this issue

  • How to create url preview in javascript?

    - by Razor Storm
    Can someone help me with creation of a url preview script in javascript? What I mean is this. Say I have a link on my site, I want the user to be able to mouse over the link, and have an image pop up that shows what the target of the link looks like. Don't worry about the css, I got that working, I just need the actual script to show the image. Currently I am doing it by showing up an iframe that actually renders the page, but this is not scalable and looks ugly. No, having the page display premade images is not an option, since the links will be linking to dynamically generated user content. thanks

  • Memory leak in chrome.extension.sendRequest()

    - by jprim
    Chrome Version : 9.0.597.19 (Build 68937) beta & current stable I have simplified my code as far as possible. I ended up with the attached extension: content.js (content script run on every site): setInterval(function() { chrome.extension.sendRequest({ }, function(response) { //Do nothing }); }, 1); background.js (background page script): chrome.extension.onRequest.addListener(function(request, sender, sendResponse) { sendResponse({ }); }); When you install this extension, you can observe it eating up memory extremely fast (I got 90MB in 1 min with 9 tabs opened). You can speed up the process by opening more tabs. Of course, the extension I am actually developing does not send requests every millisecond, but only every 3 seconds. This just slows it down, though. A user who has run it in the background for a long time with many tabs opened has reported 100MB of memory usage, and I can reproduce it to a less extreme extent, too.

When the array is constructed, instead of using it as a pointer, JavaScript calls my function. Why? What mistake, misconception do I have?
