• Server Side code Pushing Data to client Browser while current thread is busy Comet (programming)

  - by h_power11

  Hello Friends, I am writing one simple web page with bunch of textboxes and a button control. Now when user finished editing the values on this text boxes user has to click the button and this button invoke heavily process intensive algorithm on server side code based on the data received from client (Textboxes) And it could some time takes up to 30 to 45 minutes to complete the whole operation so the current thread is still inside the button click event handler function. That background task only provides one event, and the web page subscribes to it to get some text data after each stage of processing I was wandering if there is any way I can keep user up-to-date with what is the current progress on that background task. I have div element to print the current status information So I am looking for some sort of reverse mechanism then "get" and "post". I have read some articles on the Comet (programming) but I can't find any easy or definitive answer Thanks in advance

• jQuery on() method not working for appended elements

  - by behz4d

  I know I should use on() method for triggering appended elements and not use click(), so: $('#change_profile_img').on('click', function(){ alert(1); }); so the above code is working fine on any elements unless the appended elements, for example, I'm appending: $('.companylogo:first').append('<a id="change_profile_img" class="ic_change">CHANGE IMAGE</a>'); after it's appended, it's not working, but after a page refresh it works just fine. Another thing that I should mention, I'm doing the append from a modal page, it appends the button and everything but I could not trigger it anymore... I would appreciate any kind of help. Thanks

• jQuery 1.4.2 - is $("#foo").hide("normal") broken or am I crazy?

  - by karim79

  Hi all, Does anyone know why .hide("normal") does not seem to be working in jQuery 1.4.2? Is it a bug, has it been removed or am I just crazy? I've managed to duplicate this using several different scenarios. Just try this: <script type="text/javascript" src="http://ajax.googleapis.com/ajax/libs/jquery/1.4.2/jquery.min.js"></script> <script type="text/javascript"> $("button").click(function() { $("div.text").hide("normal"); }); </script> <div class="test">Hello this is a test</div> <button>Click</button>

• Mootools event leak

  - by user572263

  The example to demonstrate the issue can be found here: link text The test shows a basic Mootools class that contains an element variable with a click event attached. There’s also a “cleanup” function to remove the event and nullify the element variable. My problem is that when I loop a thousand times to create the “LeakClass” instance and clean it up, it causes a major memory leak like there’s no tomorrow. I tested this on IE8 and Chrome. On the other hand what I’ve noticed is that if I comment out the line that adds the “click” event, the code doesn’t leak. Can somebody please help me structure the class/event in a manner that it doesn’t leak. Thanks in advance.

  1st i would like to thanks all who view this and special thanks for those who answer this. today, i tested this out but it not working, so just want to know how should this code. multiple "OR" in one line $("input[name='ABC']or[name='DEF']or[name='GHI']or[name='JKL']").click(function (){ //do something }); or even put else for it like... $("input[name='ABC'][name='DEF'][name='GHI'][name='JKL']").click(function (){ //do something }else{ //do something else }); i know both code is invalid, so is that possible to code in that way? so far i code it all one by one, so my coding is very long.

• Hide and Show content based on Cookie value

  - by danit

  Here is my Jquery: $("#tool").click(function() { $(".chelp").slideToggle(); $("wrapper").animate({ opacity: 1.0 },200).slideToggle(200, function() { $("#tool img").toggle(); }); }); When you click #tool img #wrapper is hidden along with .chelp. I need to control this with a cookie, so when the user hides #wrapper it remains hidden on all pages or when they re-visit the page. I know there is a jQuery Cookie plugin, but I'd like to do this with plain Javascript rather then including another plugin. Can anyone tell me how i can build in it in plain javascript and merge with the JQuery to create a cookie, then check the cookie each time the page loads to see if #wrapper should be hidden or displayed?

• amixer volume controls applies twice

  - by user214604

  The volume increment or decrement is happening double the intended amount using amixer for my alsa driver using ./amixer -c 0 set Master 1- command. This happens becuase by default volume controls apply for both playback and capture moduels. My alsa driver config doesnt enabled any of the capture controls. even there is no capture enabled, the function from simple_none.c returns true for capture channel. All the capture volume controls are applied to my playback driver. static int is_ops(snd_mixer_elem_t *elem, int dir, int cmd, int val) case SM_OPS_IS_CHANNEL: return (unsigned int) val < s-str[dir].channels; ./amixer -c 0 set Master Playback 10+ ./amixer -c 0 set Master Playback 10 - ./amixer -c 0 set Master Capture 10+ ./amixer -c 0 set Master Capture 10 - I suspect capture is enabled by default in my system for alsa drivers. Let me know what are the things to ensure to disable the capture.

• How can I get a set of radio buttons to accept NULL (nothing checked)?

  - by Ethan

  I'm working on a Rails application where I have some a set of two radio buttons where users can click "yes" or "no". The MySQL DB column created by the ActiveRecord migration is a tinyint. If the user doesn't click either radio button I want MySQL to store NULL. (The column allows NULL.) And when they come back to edit the data, neither button should be checked. What's happening is that ActiveRecord is storing 0 and then when I come back the "No" button is checked. Rails 2.3.5 Form code (I'm using Haml): = f.radio_button( :model_attribute, true ) Yes = f.radio_button( :model_attribute, false ) No (In retrospect it probably would have been better to use a single checkbox, but it would be difficult to change that now.)

• jquery - appended element not draggable

  - by kikkoman90

  Hello, So i have one div element that i append on my DOM with a click of a link. The problem is that i should be able to move that element around, but if i append it to my DOM i can't drag it at all. So is the live()-function solution? If it is, how should i use it? I kinda don't know how. Here's the minimalistic code: element to be appended (data.html): <div id="menu"> <p>random stuff here</p> </div> jquery: $("#menu").draggable(); $("#button").click(function(){ //custom function for exists() if ($("#menu").exists()){ $("#menu").remove(); } else { $.get("data.html", function(data){ $("body").append(data); }); } });

• Buttons created through jquery don't respond to clicks

  - by Atrus

  As I've come to understand using $('.whatever').click() only works for items created initially. Additional items won't respond in the correct fashion. I was then directed to using something like $('.whatever).on('click', myFunction()). However, I'm not detecting any difference, as newly created items are not called. Here is a JSFiddle demonstration my example code: http://jsfiddle.net/atrus6/zaKZN/ My initial input plus 'Kill' will work in the correct fashion, however any additional 'input + kill's will not not do anything. Am I incorrectly using .on() or is it something else?

• Variable-step update() in game loop is falling behind, how can I get around this?

  - by ThatsGobbles

  I'm working on a minimal game engine for my next game. I'm using the delta update method like shown: void update(double delta) { // Update code that uses `delta` goes here } I have a deep hierarchy of updatable objects, with a root updatable that contains several updatables, each of which contains more updatables, etc. Normally I'd just iterate through each of the root's children and update each one, which would then do the same for its children, and so on. However, passing a fixed value of delta to the root means that by the time the leaf updatables are reached, it's been longer since delta seconds that have elapsed. This is causing noticable desyncing in my game, and time synchronization is very important in my case (I'm working on a rhythm game). Any ideas on how I should tackle this? I've considered using StopWatches and a global readable timer, but any advice would be helpful. I'm also open to moving to fixed timesteps as opposed to variable.

• jquery add remove objects

  - by Scarface

  Hey guys quick question, I have an add remove script that will add a unique element and should remove it on a click function but does not. I think it is because the added object is not in the DOM when page is loaded but I am not sure how to fix this. IF anyone has any advice I would greatly appreciate it. $(document).ready(function(){ if (action=='content-change'){ $('#droppable2-inner').empty().append('<div id="content-image"><img id="visual-background2" src=' + src + '></div><div id="drop-content" action="drop-image">x</div>'); } $("#drop-content").click(function() { $('#content-image').remove(); }); })

  I have a simple slidetoggle function that opens onclick. What I'd like to do is jump the user down to the bottom of the page following the opened div. Basically, wait for the slidetoggle to complete - then imagine clicking my jump link to pull the viewport down. Here's my code. $('#clickme').click(function() { $('#form-area').slideToggle('slow', function() { // Animation complete // what can i put here that's like my standard jumpto? }); }); <a href="#form-bottom" id="clickme">Click here</a> <div class="main" id="form-area" > Stuff </div> <a name="form-bottom"></a>
