  • How do I set a value to the Session in asp.net on an onClick event of a normal htmlElement?

    - by William Calleja
    I need to make a Function that receives a Session Key and a Session Value and call this function on a normal HTML onClick event. When this function is called the Session variable is assigned the Key I sent with the Value I sent. So far I have this: <script runat="server" type="text/C#"> protected void setSessionValue(string key, string value) { Session[key] = value; } </script> But when I try to call if like so: onclick="setSessionValue('itemID','3345');" Its not working and giving me an error. Any help? I'm using c# and asp.net but I can't use code behind and need to work everything off the page.

  • JavaScript's Associative Array / Object can't be read in functions

    - by Matrym
    At the very beginning of the javascript file, I have: var lbp = {}; lbp.defaults = { minLength: 40 }; I can successfully alert it afterwards, with: alert(lbp.defaults.minLength); But as soon as I put it inside a function, when I alert, I get "Undefined". What gives, and how do I avoid this? Is it absolutely necessary to pass this variable into each function, for example, by doing: function(lbp) { alert(lbp.defaults.minLength); } I would have thought that defining it first, it would attain global scope and not be required to be passed in? Thanks in advance for enlightening me :)

  • Some input regarding Dojo (smooth css change on mouseover)

    - by Andy Walpole
    I've been playing around with Dojo over the last couple of days. The script below changes the background position of the list item when the mouse is over the link. dojo.query('a[class=main-menu-link]').forEach(function(linkTwo) { dojo.connect(linkTwo, "onmouseover", function(evt) { dojo.query('#main-menu ul li').forEach(function(linkThree) { dojo.style(linkThree, { "backgroundPosition": "right center", }); }); You can see it in action in the right hand side menu: http://www.mechanic-one.suburban-glory.com/ I'm trying to work out the best of way of giving it a smooth transition between the two states... I've been looking on the Dojo documentation page but I'm not sure what is the best way of approaching it.

  • Where to store frequently used functions in a OOP correct way

    - by Stefan Kuijers
    I'm working on a project which I want to build up OO. Now I came with a function that checks or a value is valid. private function valid(value:*, acceptedValues:Array):Boolean { for(var i:uint = 0; i < acceptedValues.length; i++) { if (value == acceptedValues[i]) { return true; } } return false; } As you can see, the function is very general and will be accessed across different classes. Now my question is; where do I store it in a OO correct way? Thanks in advance!

  • how could I pass closure problems in order to increment a global var

    - by hyptos
    I have a simple goal, I would like to increment a variable but I'm facing the closure problem. I've read why this s happening here How do JavaScript closures work? But I can't find the solution to my problem :/ let's assume this part of code I took from the link. function say667() { // Local variable that ends up within closure var num = 666; var sayAlert = function() { alert(num); //incrementation } num++; return sayAlert; } I would like to increment num within the function and to keep the changes to num. How could I do that ? Here is the JsFiddle where I have my problem, I can't figure out how to increment my totalSize and keep it. http://jsfiddle.net/knLbv/2/ I don't want a local variable that ends up with closure.

  • How to write custom SQLite functions in Javascript inside a Webkit browser?

    - by Jay Godse
    I have just learned how to use the SQLite database for local storage in a Webkit web browser (e.g. Google Chrome or Apple Safari) using the Javascript API. For example the "Sticky Notes" application. However, I know that SQLite has a function called sqlite_create_function() that lets you add custom functions to your instance of SQLite on the fly which can then be used inside SQL queries. This function is described at sqlite.org. I also know that you can call an equivalent of this API in Ruby as described here. QUESTION: Can anybody show me how to do this in Javascript - i.e. write a custom function in Javascript that can be bound into the SQLite database at run time to be called by the SQLite engine, and all inside a Webkit browser?

  • Cannot Generate ParameterSetMetadata While Programmatically Creating A Parameter Block

    - by Steven Murawski
    I'm trying to programmatically create a parameter block for a function ( along the lines of this blog post ). I'm starting with a CommandMetadata object (from an existing function). I can create the ParameterMetadata object and set things like the ParameterType, the name, as well as some attributes. The problem I'm running into is that when I use the GetParamBlock method of the ProxyCommand class, none of my attributes that I set in the Attributes collection of the ParameterMetadata are generated. The problem this causes is that when the GetParamBlock is called, the new parameter is not annotated with the appropriate Parameter attribute. Example: function test { [CmdletBinding()] param ( [Parameter()] $InitialParameter) Write-Host "I don't matter." } $MetaData = New-Object System.Management.Automation.CommandMetaData (get-command test) $NewParameter = New-Object System.Management.Automation.ParameterMetadata 'NewParameter' $NewParameter.ParameterType = [string[]] $Attribute = New-Object System.Management.Automation.ParameterAttribute $Attribute.Position = 1 $Attribute.Mandatory = $true $Attribute.ValueFromPipeline = $true $NewParameter.Attributes.Add($Attribute) $MetaData.Parameters.Add('NewParameter', $NewParameter) [System.Management.Automation.ProxyCommand]::GetParamBlock($MetaData)

  • jQuery is not defined

    - by dole
    Hi there, I have to use an external js file, in which I load the jquery. My js file look like this: document.write('<script language="javascript" type="text/javascript" src="http://code.jquery.com/jquery-1.4.4.min.js"></script>'); (function($) { $(document).ready(function() { alert('it works!!'); }); })(jQuery); On the firefox console I get the "jQuery is not defined" and I think it is because the jQuery library is loaded after the $ function from my js file. Do you have any idea about how can I fix this? If I run the script from the FF console all works fine.

  • Abstracting the adding of click events to elements selected by class using jQuery

    - by baroquedub
    I'm slowly getting up to speed with jQuery and am starting to want to abstract my code. I'm running into problems trying to define click events at page load. In the code below, I'm trying to run through each div with the 'block' class and add events to some of its child elements by selecting them by class: <script language="javascript" type="text/javascript"> $(document).ready(function (){ $('HTML').addClass('JS'); // if JS enabled, hide answers $(".block").each(function() { problem = $(this).children('.problem'); button = $(this).children('.showButton'); problem.data('currentState', 'off'); button.click(function() { if ((problem.data('currentState')) == 'off'){ button.children('.btn').html('Hide'); problem.data('currentState', 'on'); problem.fadeIn('slow'); } else if ((problem.data('currentState')) == 'on'){ button.children('.btn').html('Solve'); problem.data('currentState', 'off'); problem.fadeOut('fast'); } return false; }); }); }); </script> <style media="all" type="text/css"> .JS div.problem{display:none;} </style> <div class="block"> <div class="showButton"> <a href="#" title="Show solution" class="btn">Solve</a> </div> <div class="problem"> <p>Answer 1</p> </div> </div> <div class="block"> <div class="showButton"> <a href="#" title="Show solution" class="btn">Solve</a> </div> <div class="problem"> <p>Answer 2</p> </div> </div> Unfortunately using this, only the last of the divs' button actually works. The event is not 'localised' (if that's the right word for it?) i.e. the event is only applied to the last $(".block") in the each method. So I have to laboriously add ids for each element and define my click events one by one. Surely there's a better way! Can anyone tell me what I'm doing wrong? And how I can get rid of the need for those IDs (I want this to work on dynamically generated pages where I might not know how many 'blocks' there are...) <script language="javascript" type="text/javascript"> $(document).ready(function (){ $('HTML').addClass('JS'); // if JS enabled, hide answers // Preferred version DOESN'T' WORK // So have to add ids to each element and laboriously set-up each one in turn... $('#problem1').data('currentState', 'off'); $('#showButton1').click(function() { if (($('#problem1').data('currentState')) == 'off'){ $('#showButton1 > a').html('Hide'); $('#problem1').data('currentState', 'on'); $('#problem1').fadeIn('slow'); } else if (($('#problem1').data('currentState')) == 'on'){ $('#showButton1 > a').html('Solve'); $('#problem1').data('currentState', 'off'); $('#problem1').fadeOut('fast'); } return false; }); $('#problem2').data('currentState', 'off'); $('#showButton2').click(function() { if (($('#problem2').data('currentState')) == 'off'){ $('#showButton2 > a').html('Hide'); $('#problem2').data('currentState', 'on'); $('#problem2').fadeIn('slow'); } else if (($('#problem2').data('currentState')) == 'on'){ $('#showButton2 > a').html('Solve'); $('#problem2').data('currentState', 'off'); $('#problem2').fadeOut('fast'); } return false; }); }); </script> <style media="all" type="text/css"> .JS div.problem{display:none;} </style> <div class="block"> <div class="showButton" id="showButton1"> <a href="#" title="Show solution" class="btn">Solve</a> </div> <div class="problem" id="problem1"> <p>Answer 1</p> </div> </div> <div class="block"> <div class="showButton" id="showButton2"> <a href="#" title="Show solution" class="btn">Solve</a> </div> <div class="problem" id="problem2"> <p>Answer 2</p> </div> </div>

  • pyschool is wrong ?

    - by geekkid
    I'm currently learning python and trying to do exercises at pyschools (if anyone knows what it is). Anyway, i have an exercise that asks me to do the following : Write a function percent(value, total) that takes in two numbers as arguments, and returns the percentage value as an integer. Here's my code: def percent(value, total): percent = value / total * 100 return int(percent) It works great in my Python Idle and it gives all the correct answers. however, when i run it in the pyschools website, it says that , for example , when the function is called with parameters 46 and 90 , the function returns 0. However, in my python idle , it correctly returns 51. What might be the problem ? Thank you very much for your help!

  • Executing functions parallelly in PHP

    - by binaryLV
    Hi! Can PHP call a function and don't wait for it to return? So something like this: function callback($pause, $arg) { sleep($pause); echo $arg, "\n"; } header('Content-Type: text/plain'); fast_call_user_func_array('callback', array(3, 'three')); fast_call_user_func_array('callback', array(2, 'two')); fast_call_user_func_array('callback', array(1, 'one')); would output one (after 1 second) two (after 2 seconds) three (after 3 seconds) rather than three (after 3 seconds) two (after 3 + 2 = 5 seconds) one (after 3 + 2 + 1 = 6 seconds) Main script is intended to be run as a permanent process (TCP server). callback() function would receive data from client, execute external PHP script and then do something based on other arguments that are passed to callback(). The problem is that main script must not wait for external PHP script to finish. Result of external script is important, so exec('php -f file.php &') is not an option.

    - by Dmitry Makovetskiyd
    I get my page content with this function: private function fetch_url($url){ $ch=curl_init($url); curl_setopt($ch, CURLOPT_RETURNTRANSFER, true); curl_setopt($ch, CURLOPT_TIMEOUT, 320); $this->doc = curl_exec($ch); $this->status_code= curl_getinfo($ch, CURLINFO_HTTP_CODE); // echo $this->doc; curl_close($ch); } The problem is that with some urls dont exist on a webpage and there is a redirect to another page.. So say if I put the parameter: http://example.com/uncategorized/ It redirect me to : http://example.com/mature/ The problem is with curl, I dont get any content.. But my aim is to get the content of that page redirect.. Is there an easy way to get the function to work in the way I want..?

  • posting to aweber with jQuery

    - by wcpro
    Im trying to post to aweber using just jquery. I have a method call like this $(function () { $('#submit').click(function () { $.post('http://www.aweber.com/scripts/addlead.pl', { meta_web_form_id: '12345', meta_split_id: '', listname: 'some_list', redirect: '', meta_redirect_onlist: '', meta_adtracking: 'my_Web_Form', meta_message: '1', meta_required: 'name,email', meta_forward_vars: '', meta_tooltip: '', email : '[email protected]', name : 'tester testing' }, function (data) { alert('data load: ' + data); }); }); }); it is supposed to take the result of the post and alert it in a box. when i try to do it manually with forms it works but redirects me to a 'form-sorry.htm' page, which is fine, just wondering if there was a way to display the end result of the post. Im guessing hte addlead.pl is just a posting page with no response.

  • how does "recent history" work on sites for php? (PHP)

    - by ggfan
    I'm not sure if there is an explanation on SO for beginners, but if so, could you provide the links. I am interested in creating a "recent viewed" function that shows what links they clicked on before. I'm not sure if this is the 'correct' way to do it, but this is what I have so far... user clicks on a link(say ad.php?posting_id=12). if the user doesn't click on the link, no cookie or session is stored for the link if the user clicks on the link, it sets a cookie for $_cookie['ad.php?posting_id=22'] Each time the user clicks, more cookies are set In the recent viewed function, it gets all the $_cookie variables and displays them. if the user wants to clear the history, just destroy all the cookies I'm not sure if this is the way to do it, but is the viable? If not, what are the steps to create a "recent viewed" function

For some reason, I am unable to access the static variables of the City class from CityModule: CityModule.as: package { public class CityModule extends MovieClip { public function CityModule() { var buildings:Array = City.getBuildings(); } } } } City.as: package { import flash.display.MovieClip; public class City extends MovieClip { private static var _buildings:Array = [ {className:'City.Generic1', type:'generic'}, {className:'City.Generic2', type:'generic'}, {className:'City.Generic3', type:'generic'} ]; public function City(){ //empty } public static function getBuildings():Array{ return _buildings; } } } Doing this gives me a "Call to a possibly undefined method getBuildings" error. If I instantiate an instance of City, I can see any public/ getters/ setters perfectly fine. But static isn't working...

  • Zend Database Adapter - Complex MySQL Query

    - by Sonny
    I have defined a function in my Navigation model that executes a query, and I was wondering if there's a more "Zendy" way of generating/executing the query. The query I'm using was proposed by Bill Karwin on another thread here for setting arbitrary record order. I tried using a prepared statement, but the values in the SIGN() function got quoted. I'm using the PDO adapter for MySQL. /** * */ public function setPosition($parentId, $oldPosition, $newPosition) { $parentId = intval($parentId); $oldPosition = intval($oldPosition); $newPosition = intval($newPosition); $this->getAdapter()->query(" UPDATE `navigation` SET `position` = CASE `position` WHEN $oldPosition THEN $newPosition ELSE `position` + SIGN($oldPosition - $newPosition) END WHERE `parent_id` = $parentId AND `position` BETWEEN LEAST($oldPosition, $newPosition) AND GREATEST($oldPosition, $newPosition) "); return $this; }

  • c++: Reference array of maps

  • jQuery Supersized Plugin callback when slideshow finishd

    - by Nic Hubbard
    I am using the Supersized jQuery plugin which makes images fullscreen and also implements a slideshow. Currently, this plugin does not have a callback for when the slideshow is finished, rather, it just continually repeats. Is there a way that I could trigger a function after the last slide is shown? Currently, I have it working to trigger a function when the last slide STARTS to be shown, as I have a setInterval which checks for the "last" class on the slideshow images. But, this runs the function when that last slide starts, not when it is finished. Does anyone have ideas on how I could accomplish this?

  • How to make Dajax callback into scoped object

    I cant seem to find a way to make django-dajaxice have its callback inside same scoped object from which made the initial call. MyViewport = Ext.extend(MyViewportUi, { initComponent: function() { MyViewport.superclass.initComponent.call(this); }, LoadRecordsCallback: function(data){ if(data!='DAJAXICE_EXCEPTION') { alert(data); } else { alert('DAJAXICE_EXCEPTION'); } }, LoadRecords: function(){ Dajaxice.Console.GetUserRecords(this.LoadRecordsCallback); } }); var blah = new MyViewport(); blah.LoadRecords(); I'm on django, and like the calling syntax to django-dajaxice. I'm using Extjs 3.2 and tried passing a Ext.createCallback but Dajax's returning eval seems to only want a string for the callback.

  • Creating full, global clang+llvm environment

    - by Griwes
    What is the easiest way to setup full Clang, libc++ and LLVM as default global toolchain? All of my attempts to build it, in most of the configurations I could think of, resulted in working Clang, but it didn't use libc++ headers, but default GCC's libstd++'s ones, resulting in numerous faults in incompatible pieces of library code. I would like it working out of the box, without having to do magic in .bashrc or passing all those -stdlib=libc++ and -lc++ to compiler and linker.
