• innerhtml not working on blogger

  - by HAnlin Cal

  I'm working on a simple vote system. It works fine when the two files are together(locally). However, when I publish it on blogger, it is unable to output the results. (on click the vote gets registered on the webhost, but the results just don't show!) heres my code: <script type="text/javascript"> function getVote(int) { if (window.XMLHttpRequest) {// code for IE7+, Firefox, Chrome, Opera, Safari xmlhttp=new XMLHttpRequest(); } else {// code for IE6, IE5 xmlhttp=new ActiveXObject("Microsoft.XMLHTTP"); } xmlhttp.onreadystatechange=function() { if (xmlhttp.readyState==4 && xmlhttp.status==200) { document.getElementById("poll").innerHTML=xmlhttp.responseText; } } xmlhttp.open("GET","http://pacontest.eu.pn/poll_vote.php?vote="+int,true); xmlhttp.send(); } </script> <div id="poll"> <h3>Do you like this?</h3> <form> Yes: <input type="radio" name="vote" value="0" onclick="getVote(this.value)" /> No: <input type="radio" name="vote" value="1" onclick="getVote(this.value)" /> </form> </div>

• Undesired Output of Crontab Job Using CURL

  - by Russell C.

  I have written a perl script that runs as a daily crontab job that uploads files to Amazon S3 via CURL. I want the output of the cron job emailed to me which works fine but I don't want that email to include messages related to the CURL upload (only those message my script is outputting). Here are the CURL related messages I'm seeing in the daily email right now: % Total % Received % Xferd Average Speed Time Time Time Current Dload Upload Total Spent Left Speed 0 230M 0 0 0 0 0 0 --:--:-- --:--:-- --:--:-- 0 0 230M 0 0 0 544k 0 1519k 0:02:35 --:--:-- 0:02:35 1807k 0 230M 0 0 0 1744k 0 1286k 0:03:03 0:00:01 0:03:02 1342k 1 230M 0 0 1 2880k 0 1219k 0:03:13 0:00:02 0:03:11 1250k 1 230M 0 0 1 4016k 0 1198k 0:03:17 0:00:03 0:03:14 1218k 2 230M 0 0 2 5168k 0 1186k 0:03:19 0:00:04 0:03:15 1202k 2 230M 0 0 2 6336k 0 1181k 0:03:19 0:00:05 0:03:14 1157k 3 230M 0 0 3 7488k 0 1177k 0:03:20 0:00:06 0:03:14 1147k 3 230M 0 0 3 8592k 0 1167k 0:03:22 0:00:07 0:03:15 1142k 4 230M 0 0 4 9744k 0 1166k 0:03:22 0:00:08 0:03:14 1145k 4 230M 0 0 4 10.6M 0 1163k 0:03:23 0:00:09 0:03:14 1142k 5 230M 0 0 5 11.7M 0 1161k 0:03:23 0:00:10 0:03:13 1140k 5 230M 0 0 5 12.8M 0 1158k 0:03:23 0:00:11 0:03:12 1133k 6 230M 0 0 6 13.9M 0 1155k 0:03:24 0:00:12 0:03:12 1138k 6 230M 0 0 6 15.0M 0 1155k 0:03:24 0:00:13 0:03:11 1138k 7 230M 0 0 7 16.1M 0 1152k 0:03:25 0:00:14 0:03:11 1131k 7 230M 0 0 7 17.2M 0 1152k 0:03:25 0:00:15 0:03:10 1132k 7 230M 0 0 7 18.4M 0 1152k 0:03:24 0:00:16 0:03:08 1140k I am using a simple Perl system() call to invoke CURL.

• Filtering a select list via input box & jquery

  - by zSysop

  Hi all, I was wondering if i could get some help with filtering a select list using an input box via jquery. Here's what my js looks like, but it doesnt seem to work. I'm guessing this is because options within a select list are not hide-able. <script type="text/javascript"> $(document).ready(function() { $("#inputFilter").change(function() { var filter = $(this).val(); $("#selectList option").each(function() { var match = $(this).text().search(new RegExp(filter, "i")); if (match > 0) { $(this).show(); // Does not work } else $(this).hide(); }); }); }); </script> and here's my html <input id="inputFilter" /> <select id="selectList"> <option value="1111" text="1111 - London" /> <option value="1112" text="1111 - Paris" /> </select>

• Change css property in chain - JavaScript

  - by SilverDeveloper

  I'm using MooTools 1.4.5 and I want to change cursor before calling function that takes some time and after finished same function set cursor to default. I was not successful. After that I made simple example to change background color via plain JavaScript (no jQuery or MooTools plugin) and again I was not successful. Here is my code. <html xmlns="http://www.w3.org/1999/xhtml"> <head runat="server"> <title></title> </head> <body> <form id="form1" runat="server"> <div> </div> </form> </body> <script type="text/javascript"> <!-- document.body.style.background = 'red'; setTimeout(function () { }, 1250); document.body.style.background = 'yellow'; //--> </script> </html> First at all I set background color to red, and after delay to yellow. I assumed that the background color will bi set to red and after delay to yellow. It doesn't work. When page is loaded background color is yellow (last line). If I insert alert function in a middle of lines where sets background color everything works fine (background color is red, click to message box, background color is yellow). Why it works so? Only last changing style is affected. I need something like that to change pointer before calling function that takes 10 seconds and setting cursor to default value after function is done.

• Canvas maximization bug?

  - by mitjak

  I must've killed over an hour on what seems to me like strange behaviour that happens in Firefox, Safari and Chrome. Here is some code: <!doctype html> <html> <head> <title>Watch me grow scrollbars!</title> </head> <body onload="resizeCanvas()"> <canvas id="canvas"></canvas> </body> </html> <script type="application/javascript"> function resizeCanvas() { var canvas = document.getElementById("canvas"); canvas.setAttribute("height", window.innerHeight); canvas.setAttribute("width", window.innerWidth); } </script> Basically, the canvas always seems to maximize 'too much', and the window grows scrollbars on both sides. I've tried using various ways of obtaining the document dimensions, including nesting canvas in a 100% wide & tall absolutely positioned div, as well as extracting the document.documentElement.clientWidth/Height properties. Just to be sure I'm not going insane, I've placed an image in place of the canvas, and voila, the same code worked perfectly to stretch the image out to document dimensions. What am I doing wrong here? I'm too tired to understand. Must.. drink.. something.

• The post->success->data variable is empty..

  - by Asaf

  Hello, I tried sending some data like so: <form action="http://www.someurl.com/something.php" id="login"> <input type="textbox" id="UserName" value="user"> <input type="textbox" id="Password" value="password"> <input type="submit" value="submit"> </form> <div id="result"></div> <script type="text/javascript"> $('form#login').submit(function() { $.post($('form#login').attr('action'), $('form#login').serialize(), function(data) { $('#result').html(data+'222') }); return false; }); </script> Now, the value of #result div change to 222... that is: the post was successful but for some reason there is no data, and when I go directly to something.php and post manually, it does bring back data (am I mistaken or does the post(success(data)) variable returns the whole page returned after you post something? if so, how could it be?) Thank you very much for your help

• Define an empty array in Perl class new()

  - by Laimoncijus

  Hi, I am just beginner with Perl, so if it sounds stupid - sorry for that :) My problem is - I am trying to write a class, which has an empty array, defined in constructor of a class. So I am doing this like this: package MyClass; use strict; sub new { my ($C) = @_; my $self = { items => () }; bless $self, ref $C || $C; } sub get { return $_[0]->{items}; } 1; Later I am testing my class with simple script: use strict; use Data::Dumper; use MyClass; my $o = MyClass->new(); my @items = $o->get(); print "length = ", scalar(@items), "\n", Dumper(@items); And while running the script I get following: $ perl my_test.pl length = 1 $VAR1 = undef; Why am I doing wrong what causes that I get my items array filled with undef? Maybe someone could show me example how the class would need to be defined so I would not get any default values in my array? Thanks!

• Display one div if nothing is selected

  - by Levani

  I use this javascript to display different div classes upon selection. I need to display one div class if nothing is selected, for example when page is loaded, and that replace it with one of the divs according to the selection... <script type="text/javascript"><!-- var lastDiv = ""; function showDiv(divName) { // hide last div if (lastDiv) { document.getElementById(lastDiv).className = "hiddenDiv"; } //if value of the box is not nothing and an object with that name exists, then change the class if (divName && document.getElementById(divName)) { document.getElementById(divName).className = "visibleDiv"; lastDiv = divName; } } //--> </script> css: <style type="text/css" media="screen"><!-- .hiddenDiv { display: none; } .visibleDiv { display: block; border: 1px grey solid; } --></style> HTML: <form id="FormName" action="blah.php" method="get" name="FormName"> <select name="selectName" size="1" onChange="showDiv(this.value);"> <option value="">Choose One...</option> <option value="one">first</option> <option value="two">second</option> <option value="three">third</option> </select> </form> <p id="one" class="hiddenDiv">This is paragraph 1.</p> <p id="two" class="hiddenDiv">This is paragraph 2.</p> <p id="three" class="hiddenDiv">This is paragraph 3.</p> Can anyone please help?

• Visual Studio not recognizing "BuildStep"

  - by AmbiguousX

  I'm trying to add an automatic post-build trigger to run NDepend after an automated team build in TFS 2010. NDepend's website provided code for integrating this capability, and so I have pasted their code into my .csproj file where they said for it to go, but I receive errors on the build. The errors refer to two of the three "BuildStep" tags I have in the code snippet. The following two snippets are giving me errors: <BuildStep TeamFoundationServerUrl="$(TeamFoundationServerUrl)" BuildUri="$(BuildUri)" Message="Running NDepend analysis"> <Output TaskParameter="Id" PropertyName="StepId" /> </BuildStep> and <BuildStep TeamFoundationServerUrl="$(TeamFoundationServerUrl)" BuildUri="$(BuildUri)" Id="$(StepId)" Status="Failed" /> However, this code snippet is NOT throwing up any problems: <BuildStep TeamFoundationServerUrl="$(TeamFoundationServerUrl)" BuildUri="$(BuildUri)" Id="$(StepId)" Status="Succeeded" /> I just don't understand why one works fine and a nearly identically laid out BuildStep tag does not. Is there something simple that I'm just overlooking? EDIT: Here is how it looks all together, if this makes a difference: <Target Name="NDepend" > <PropertyGroup> <NDPath>c:\tools\NDepend\NDepend.console.exe</NDPath> <NDProject>$(SolutionDir)MyProject.ndproj</NDProject> <NDOut>$(TargetDir)NDepend</NDOut> <NDIn>$(TargetDir)</NDIn> </PropertyGroup> <Exec Command='"$(NDPath)" "$(NDProject)" /OutDir "$(NDOut)" /InDirs "$(NDIn)"'/> </Target> <Target Name="AfterBuild"> <BuildStep TeamFoundationServerUrl="$(TeamFoundationServerUrl)" BuildUri="$(BuildUri)" Message="Running NDepend analysis"> <Output TaskParameter="Id" PropertyName="StepId" /> </BuildStep> <PropertyGroup> <NDPath>c:\tools\NDepend\NDepend.console.exe</NDPath> <NDProject>$(SolutionRoot)\Main\src\MyProject.ndproj</NDProject> <NDOut>$(BinariesRoot)\NDepend</NDOut> <NDIn>$(BinariesRoot)\Release</NDIn> </PropertyGroup> <Exec Command='$(NDPath) "$(NDProject)" /OutDir "$(NDOut)" /InDirs "$(NDIn)"'/> <BuildStep TeamFoundationServerUrl="$(TeamFoundationServerUrl)" BuildUri="$(BuildUri)" Id="$(StepId)" Status="Succeeded" /> <OnError ExecuteTargets="MarkBuildStepAsFailed" /> </Target> <Target Name="MarkBuildStepAsFailed"> <BuildStep TeamFoundationServerUrl="$(TeamFoundationServerUrl)" BuildUri="$(BuildUri)" Id="$(StepId)" Status="Failed" /> </Target> EDIT: Added a bounty because I really need to get this going for my team. Thank you in advance!

• Get dragged / saved items state back from Sql Server

  - by user571507

  Ok i saw many post's on how to serialize the value of dragged items to get hash and they tell how to save them. Now the question is how do i persist the dragged items the next time when user log's in using the has value that i got eg: <ul class="list"> <li id="id_1"> <div class="item ui-corner-all ui-widget ui-widget-content"> </div> </li> <li id="id_2"> <div class="item ui-corner-all ui-widget ui-widget-content"> </div> </li> <li id="id_3"> <div class="item ui-corner-all ui-widget ui-widget-content"> </div> </li> <li id="id_4"> <div class="item ui-corner-all ui-widget"> </div> </li> </ul> which on serialize will give "id[]=1&id[]=2&id[]=3&id[]=4" Now think that i saved it to Sql server database in a single field called SortOrder. Now how do i get the items to these order again ? the code to make these sort is below,without which people didn't know which library i had used to sort and serialize <script type="text/javascript"> $(document).ready(function() { $(".list li").css("cursor", "move"); $(".list").sortable(); }); </script>

• How to remove empty tables from a MySQL backup file.

  - by user280708

  I have multiple large MySQL backup files all from different DBs and having different schemas. I want to load the backups into our EDW but I don't want to load the empty tables. Right now I'm cutting out the empty tables using AWK on the backup files, but I'm wondering if there's a better way to do this. If anyone is interested, this is my AWK script: EDIT: I noticed today that this script has some problems, please beware if you want to actually try to use it. Your output may be WRONG... I will post my changes as I make them. # File: remove_empty_tables.awk # Copyright (c) Northwestern University, 2010 # http://edw.northwestern.edu /^--$/ { i = 0; line[++i] = $0; getline if ($0 ~ /-- Definition/) { inserts = 0; while ($0 !~ / ALTER TABLE .* ENABLE KEYS /) { # If we already have an insert: if (inserts > 0) print else { # If we found an INSERT statement, the table is NOT empty: if ($0 ~ /^INSERT /) { ++inserts # Dump the lines before the INSERT and then the INSERT: for (j = 1; j <= i; ++j) print line[j] i = 0 print $0 } # Otherwise we may yet find an insert, so save the line: else line[++i] = $0 } getline # go to the next line } line[++i] = $0; getline line[++i] = $0; getline if (inserts > 0) { for (j = 1; j <= i; ++j) print line[j] print $0 } next } else { print "--" } } { print }

• jQuery: If, Else with buttons error

  - by Wipqozn

  I'm running into an odd error. I'm working in Django 1.2, and have implemented the commenting framework. I'm trying to attach a hide/show button to each comment field, but whenever click on a hide/show button, it behaves as if each hide/show button beneath it on the page was clicked. Here's the jQuery code: <input type="Button" id="hideShow" name="hide/show" value="Hide"></input> <script> $("#hideShow").click(function() { if($(this).val() == "Hide") { $("textarea").hide("fast"); $(this).val("Show"); } else { $("textarea").show("fast"); $(this).val( "Hide"); } }); </script> So, when I click the Hide/show button, it will perform the action for each button beneath the clicked button + once for the button itself. So If I click a button, and there are two buttons beneath it, and value=hide it will first hide the 'textarea', than show the text area, than finally hide it again. I'm new to jQuery (although I do have experience in other languages), and I have an -idea- why it's not working: that whenever an action is performed jQuery jumps to the first one, than continues down the page looking for any other actions performed, and responds to each one. So it comes to my first button, sets it as being clicked, and so when jQuery comes across the other buttons it views them all as being 'clicked' and performs actions accordingly. I've thought of a semi-solution to my problem, putting in a variable which tracks how many times it has gone through, and than acting based on -that- action. But I would rather not do that, since it's not really a solution to the problem at hand but a work around. Any input is appreciated.

• Why does my DIV clip its child DIV when jQuery moves it in IE?

  - by Ben Saufley

  I have two divs, both with position:absolute;, one inside the other. The parent isn't in a place where it can be set as position:relative without an extra layer of complexity (there are a lot of other elements around it that I'd have to account for to put it where it needs to be, which is at the very top of the page, over everything). The child element is made to stick off the bottom of the parent. In Chrome, Safari, Firefox, it all works splendidly. In IE, it works until jQuery moves the parent element - at which point the parent element clips the child, so you can barely see the top of the child. I feel like I've read about this, about IE clipping child elements, but I can't seem to find an answer that applies to my case. It's pretty simple, basically: <div id="parent" style="position:absolute;top:0;left:0;"> [content] <div id="tab" style="position:absolute;bottom:-30px;left:0;width:64px;height:32px;background-image:(...);"></div> </div> <script> $(document).ready( function() { $("#tab").click(function() { $("#parent").animate({"top":"-50px"},300); }); }); </script>

• In Perl v 5.10.1 on Windows, my variable loses it's value

  - by Sylvia

  I hope this is something straightforward that I'm doing wrong. I saw something online about "variable suicide" that looked good, but it was for an older version and I'm on 5.10.1. Anyway - a variable that I declared - $RootDirectory - just suddenly loses it's value, and I can't figure out why. Here's a script to reproduce the problem. When I run through the script in debug mode (perl -d) I can get it to print out the $RootDirectory at line 21 and 26. But it's gone by line 30. use strict; my $RootDirectory; my @RootDirectories; @RootDirectories = ( 'c:\\P4\\EDW\\PRODEDW\\EDWDM\\main\\db\\' ,'c:\\P4\\EDW\\PRODEDW\\EDWADS\\main\\db\\' ,'c:\\P4\\EDW\\PRODEDW\\FJE\\main\\db\\' ); foreach $RootDirectory (@RootDirectories) { # $RootDirectory = 'c:\\P4\\EDW\\PRODEDW\\EDWDM\\main\\db\\'; # print ' In foreach ' . $RootDirectory. "\n"; RunSchema (); } exit(0); sub RunSchema() { # print ' In RunSchema ' . $RootDirectory. "\n"; CreateTables (); } sub CreateTables() { # print ' In CreateTables ' . $RootDirectory. "\n"; SQLExecFolder ('tbl'); } sub SQLExecFolder() { print ' In SQLExecFolder ' . $RootDirectory. "\n"; # Variable $RootDirectory value is gone by now }

• PHP – Slow String Manipulation

  - by Simon Roberts

  I have some very large data files and for business reasons I have to do extensive string manipulation (replacing characters and strings). This is unavoidable. The number of replacements runs into hundreds of thousands. It's taking longer than I would like. PHP is generally very quick but I'm doing so many of these string manipulations that it's slowing down and script execution is running into minutes. This is a pain because the script is run frequently. I've done some testing and found that str_replace is fastest, followed by strstr, followed by preg_replace. I've also tried individual str_replace statements as well as constructing arrays of patterns and replacements. I'm toying with the idea of isolating string manipulation operation and writing in a different language but I don't want to invest time in that option only to find that improvements are negligible. Plus, I only know Perl, PHP and COBOL so for any other language I would have to learn it first. I'm wondering how other people have approached similar problems? I have searched and I don't believe that this duplicates any existing questions.

• Dynamic table memory usage

  - by Dan

  I use a dynamic table: <html> <body> <button id="button">Build table</button> <div id="container"> <script type="text/javascript"> window.onload=function(){ var table = null; var row = "<tr><td>111111111111111111111111111111111111111111111111111111</td>" + "<td>222222222222222222222222222222222222222222222222222222</td>" + "<td>333333333333333333333333333333333333333333333333333333</td></tr>"; var data = null; for (var i = 0; i < 2000; i++){ data += row; } var obj = document.getElementById("button"); obj.onclick=function buildTable(){ document.getElementById("container").innerHTML = "<div><table><tbody>" + data + "</tbody></table></div>"; }; }; </script> </body> </html> Using chromes task manager, each time new data is loaded the memory usage increases considerably and doesn't go down, so after some time the app consumes a lot of memory and requires the browser to be closed. Is there any change in the code I can use to solve this or is it a browser side problem?
