  • Is it possible to get multiple forms to work with one ajax post function

    - by Scarface
    Hey guys I have a system where there is one form for each friend you have and I used to have an ajax post function for each form, but I want to save code and was wondering if it was possible to get multiple forms to work with just one post function. If anyone has any advice on how to achieve this I would appreciate it. For example <div id="message"> <form id='submit' class='message-form' method='POST' > <input type='hidden' id='to' value='friend1' maxlength='255' > Subject<br><input type='text' id='subject' maxlength='50'><br> Message<br><textarea id='message2' cols='50' rows='15'></textarea> <input type='submit' id='submitmessage' class='responsebutton' value='Send'> </form> </div> $(document).ready(function(){ $(".message-form").submit(function() { $("#submitmessage").attr({ disabled:true, value:\"Sending...\" }); var to = $('#to').attr('value'); var subject = $('#subject').attr('value'); var message = $('#message2').attr('value'); $.ajax({ type: "POST", url: "messageprocess.php", data: 'to='+ to + '&subject=' + subject + '&message=' + message, success: function(response) { if(response == "OK") { $('.message-form').html("<div id='message'></div>"); $('#message').html("<h2>Email has been sent!</h2>") .append("<p>Please wait...</p>") .hide() .fadeIn(1500, function() { $('#message').append(\"<img id='checkmark' src='images/check.png' />\"); });

  • ruby on rails basics help

    - by CHID
    Hi, i created a scaffolded application in rails by the name of product. The product_controller.rb file contains the following. class ProductsController ApplicationController def new @product = Product.new respond_to do |format| format.html # new.html.erb format.xml { render :xml = @product } end end def create @product = Product.new(params[:product]) respond_to do |format| if @product.save flash[:notice] = 'Product was successfully created.' format.html { redirect_to(@product) } format.xml { render :xml = @product, :status = :created, :location = @product } else format.html { render :action = "new" } format.xml { render :xml = @product.errors, :status = :unprocessable_entity } end end end Now when the url http://localhost:3000/products/create is given Where new product link is clicked, control is transferred to new definition in the controller class and then an instance variable @product is created. BUT WHERE IS THIS VARIABLE PASSED? The funtion inturn calls new.rhtml which contains <% form_for(@product) do |f| % #all form elments declaration <% f.submit "Create" % <%= end % Here @product is initialized in the controller file and passed to this new.rhtml. So where does form_for(@product) gets the data? How does the control gets tranfered to create function in controller file when submit button is clicked? No where action is specified to the controller file. in the create function, wat does redirec_to(@product) specify where @product is an object received from the new.html file... I am very much confused on the basics of ROR. Somone pls help me clarify this. pardon me for making such a big post. I have lots of doubts in this single piece of code

  • PHP, MySQL, Memcache / Ajax Scaling Problem

    - by Jeff Andersen
    I'm building a ajax tic tac toe game in PHP/MySQL. The premise of the game is to be able to share a url like mygame.com/123 with your friends and you play multiple simultaneous games. The way I have it set up is that a file (reload.php) is being called every 3 seconds while the user is viewing their game board space. This reload.php builds their game boards and the output (html) replaces their current game board (thus showing games in which it is their turn) Initially I built it entirely with PHP/MySQL and had zero caching. A friend gave me a suggestion to try doing all of the temporary/quick read information through memcache (storing moves, and ID matchups) and then building the game boards from this information. My issue is that, both solutions encounter a wall when there is roughly 30-40 active users with roughly 40-50 games running. It is running on a VPS from VPS.net with 2 nodes. (Dedicated CPU: 1.2GHz, RAM: 752MB) Each call to reload.php peforms 3 selects and 2 insert queries. The size of the data being pulled is negligible. The same actions happen on index.php to build the boards for the initial visit. Now that the backstory is done, my question is: Would there be a bottleneck in that each user is polling the same file every 3 seconds to rebuild their gameboards, and that all users are sitting on index.php from which the AJAX calls are made within the HTML. If so, is it possible to spread the users' calls out over a set of files designated to building the game boards (eg. reload1.php 2, 3 etc) and direct users to the appropriate file. Would this relieve the pressure? A long winded explanation; however, I didn't have anywhere else to ask. Thanks very much for any insight.

  • selenium and firefox timeout behavior

    - by Md. Reazul Karim
    I am facing this strange timeout behavior. I tried to load some page using: WebDriver drv = new FirefoxDriver(); drv.manage().timeouts().implicitlyWait(10, TimeUnit.SECONDS); drv.get(url); String email = ""; try { WebElement aElem = Util.safeFindElementByXpath(drv, "//p[1]/a[1]"); if (aElem != null) { email = aElem.getAttribute("href"); } } catch (Exception e) { } drv.quit(); return email; The safeFindElementByXpath is: static WebElement safeFindElementByXpath(WebDriver driver, String xpath) { try { return driver.findElement(By.xpath(xpath)); } catch (NoSuchElementException e) { return null; } } Now I set the firefox network.http.connection-timeout and network.http.connection-retry-timeout both to 10. Now if I restart the firefox I can see the new values. But if I try to run the above code - the firefox window opens and it waits for a particular website for a long time. Hence I open another tab in the same firefox window and check the values of timeout and find them to be 90 and 250. If I change the values on that same window, the selenium code immediately finishes requesting for the page (ie it goes after the exception block). So the thing is that the same code will work on many sites and I don't know beforehand which site is invalid/down and I was thinking of putting this code in a separate thread and kill the thread after some time from the calling thread. But that is not possible I guess because the child thread has no way to poll anything as it is stuck at page request and can't go to the polling code afterwards. Now the thing is that I want any kind of hack/workaround to accomplish this: try getting the emails for good sites and if there are bad sites just give up after a certain period (press the panic button sorta thing). Thanks

  • http connection timeout issues

    - by Mark
    I'm running into an issue when i try to use the HttpClient connecting to a url. The http connection is taking a longer time to timeout, even after i set a connection timeoout. int timeoutConnection = 5000; HttpConnectionParams.setConnectionTimeout(httpParameters, timeoutConnection); int timeoutSocket = 5000; HttpConnectionParams.setSoTimeout(httpParameters, timeoutSocket); It works perfect most of the time. However, every once in while, the http connection runs for ever and ignore the setconnectiontimeout, especailly when the phone is connected to wifi, and the phone was idling. So after the phone is idling, the first time i try to connect, the http connection ignores the setconnectiontimeout and runs forever, after i cancel it and try again, it works like charm everytime. But that one time that doesn't work it creates a threadtimeout error, i tried using a different thread, it works, but i know that the thread is running for long time. I understand that the wifi goes to sleep on idle, but i dont understand why its ignoring the setconnectiontimeout. Anyone can help, id really appreciated.

  • Background Image Overlapped Problem with jQuery

    - by Devyn
    Hi, Here is my working page. I attached buttons to white bishop and you can move around but left images are overlapped by right images. I think the problem is with CSS. The brief structure is here. <script> $(document).ready(function(){ $('#top').click(function(){ $('#p81').animate({top: "-=64px"}, 100); }); </script> <style> div.chess_board{ height: 512px; position: relative; width: 512px; } div.chess_square{ height:64px; position: absolute; width:64px; } div.chess_square.white { background: none repeat scroll 0 0 #ffffff; } . . . div.chess_piece{ background-image: url("sprite.png"); height: 64px; width: 64px; position: absolute; } div.chess_piece.bishot.white{ background-position: -64px 0; } </style> <div class="chess_board"> <div id="b81" class="chess_square white" style="top: 448px; left: 64px;"> <div class="chess_square_inner"></div> <div id="p81" class="chess_piece bishot white"></div> </div> </div> <input type="button" id="top" value="top" />

    How do i introduce validation before remote_form_for submits? I have javascript function called validateForm(). I am able to call it before the AJAX request process. I tried to use return false and event.preventDefault. But there seems to be no effect.

  • Problems with multi-line comments jquery

    - by c0mrade
    Hello, I'm making a image website with a bunch of images on the website, and below every image there is possibility of commenting the image and after that comments gets displayed without page loading and the comment content, the problem is when I have long comments which break the current line they don't get displayed since my comment box css overflow is hidden. Here is example : This is a comment - This is displayed properly This is a comment This is a comment This is a comment - this is not displayed properly since it break line. Here is the jQuery code for this : $.ajax({ type: "POST", url: "<?=base_url()?>imagesform/post_comment", data: datas, success: function () { $("#image-comments-" + image_id).attr("class", "comments"); $("#image-comments-" + image_id).append("<li id=\"new_append_" + image_id+ "\">" + $("#image").find(".comment").val() + "</li>").children(':last').height($('.comments li:last').height()).hide().slideDown(500, function () { var bodyHeight = $('html').height(); $('.addComment').fadeOut(300, function () { $('html').height(bodyHeight); }); }); alert($("#image").find(".comment").val()); } }); Here the $("#image").find(".comment").val() is the value of the text-area in which comment is inputted, when I alert it the whole multi line input is there put its not being appended to the li properly, that is part when I get confused, any suggestions why only part of the inputted string is appended?

  • How to do something when AVQueuePlayer finishes the last playeritem

    I've got an AVQueuePlayer which I'm creating from an array of 4 AVPlayerItems, and it all plays fine. I want to do something when the last item in the queue finishes playing, I've looked a load of answers on here and this is the one that looks most promising for what I want: The best way to execute code AFTER a sound has finished playing In my button handler i have this code: static const NSString *ItemStatusContext; [thePlayerItemA addObserver:self forKeyPath:@"status" options:0 context:&ItemStatusContext]; [[NSNotificationCenter defaultCenter] addObserver:self selector:@selector(playerItemDidReachEnd) name:AVPlayerItemDidPlayToEndTimeNotification object:thePlayerItemA]; theQueuePlayer = [AVQueuePlayer playerWithPlayerItem:thePlayerItemA]; [theQueuePlayer play]; and then I have a function to handle playerItemDidReachEnd: - (void)playerItemDidReachEnd:(NSNotification *)notification { // Do stuff here NSLog(@"IT REACHED THE END"); } But when I run this I get an Internal Inconsistency Exception: An -observeValueForKeyPath:ofObject:change:context: message was received but not handled.

  • Error: 'Sys' is undefined

    - by thegunner
    Hi, When I moved my website over to another server I've noticed now that ajax doesn't appear to be working. When I remote desktop to the server and go to the url on the server i.e. http://myserver/mywebsite ... everything works ok. When I open up the website in visual studio on the server it works as no problem as well. It's only when I connect remotely that the 'javascript' error occurs. To my web.config I've added: <httpHandlers> <remove verb="*" path="*.asmx"/> <add verb="*" path="*.asmx" validate="false" type="System.Web.Script.Services.ScriptHandlerFactory, System.Web.Extensions, Version=3.5.0.0, Culture=neutral, PublicKeyToken=31BF3856AD364E35"/> <add verb="*" path="*_AppService.axd" validate="false" type="System.Web.Script.Services.ScriptHandlerFactory, System.Web.Extensions, Version=3.5.0.0, Culture=neutral, PublicKeyToken=31BF3856AD364E35"/> <add verb="GET,HEAD" path="ScriptResource.axd" type="System.Web.Handlers.ScriptResourceHandler, System.Web.Extensions, Version=3.5.0.0, Culture=neutral, PublicKeyToken=31BF3856AD364E35" validate="false"/> </httpHandlers> <httpModules> <add name="ScriptModule" type="System.Web.Handlers.ScriptModule, System.Web.Extensions, Version=3.5.0.0, Culture=neutral, PublicKeyToken=31BF3856AD364E35"/> </httpModules> I've tried <compilation debug="false"/> and tried emptying web history and still no luck.

  • Making IE "forget" information entered in form when using back button.

    - by typoknig
    I have a page with a form where many of the fields are populated from variables passed in the URL. Those fields are disabled (NON-EDITABLE) and are only there for the user to view. The remaining fields require user input and are NOT disabled (EDITABLE). When the form is submitted a confirmation page comes up. It may be the case that the user needs to submit several of these forms where the NON-EDITABLE information is identical from form to form, so being able to go back to the form page from the confirmation page would save a lot of time. The way I want this to work is when a user presses the back button all the NON-EDITABLE fields are populated, but the EDITABLE fields are blank. This is what Firefox is doing, but IE8 is does not "forget" what has been entered in the EDITABLE fields. To disable the cache the following appears at the beginning of my page AND at the end of my page. <head> <meta http-equiv="Pragma" content="no-cache"/> <meta http-equiv="Cache-Control" content="no-store"/> <head/> What more must I do to make IE forget what was entered in the EDITABLE fields when the back button is pressed? All of my pages are generated with PHP if that matters. EDIT: It appears to me that this is a problem of IE caching my page even though I have told it not to. Are my meta tags correct? Do I need to do something else to prevent IE from caching my page?

  • Firefox "intelligently" and silently fixes incorrect file references in CSS and Scripts at runtime.

    - by bobsoap
    Well this is a really weird issue, I really didn't find anything on this elsewhere so I thought I'd address it here. Say I have an "image.jpg" and accidentally reference it in the CSS like so: url(imag.jpg) Note the missing "e". Now for me, Firefox is so incredibly clever that it will still find the correct image, but NOT SPIT OUT A WARNING. So I assume that everything is ok. But later, when I test the page in any other browser, all of a sudden the image doesn't display (and rightly so). That's because Firefox thought it was a good idea to correct my error without telling me. This becomes more critical with scripts. Firefox will also auto-correct a typo in a reference. I just wasted a whole hour scratching my head and trying to debug an ajax function in Webkit - turns out, I just had a typo where I included the file. Why on earth does Firefox do this without telling, and where the heck can I turn this off? This has first occured somewhere around FF 3.0 and still persists in 3.6.3. /rant an thank fo any inpu ;)

  • Jquery ajax ($.ajax) not working on chrome. please help

    - by racky
    Hi, I need a little help to figure out why the following code does not work on google chrome 5/windows xp. It works well on all other browsers (IE, FF, Safri, Opera etc).

  • mod_rewrite failing on uppercase dir

    - by user1855277
    I have a very basic mod_rewrite in a .htaccess file which I'm sure worked last time I looked at it, but now it is doing strange things with the case of the REQUEST_URI. It's intended purpose is to rewrite sub-domains to a given file, passing the subdomain as a php var of bnurl. Here is my code: RewriteCond %{REQUEST_URI}= "RSDEV/location/" [NC] RewriteCond %{HTTP_HOST} . RewriteCond %{HTTP_HOST} !^www\. [NC] RewriteCond %{HTTP_HOST} ^([^.]+)\.mydomain\.co\.uk(:80)? [NC] RewriteRule ^RSDEV/location/$ RSDEV/newmain.php?bnurl=%1&accesstype=new [NC,L] Now, typing joebloggs.mydomain.co.uk/RSDEV/location/ into my web browser comes back with the response "The requested URL /RSDEV/location/ was not found on this server" which is a correct statement because /RSDEV/location/ is not a real directory, but why did it not rewrite to RSDEV/newmain.php?bnurl=joebloggs&accesstype=new as expected? Now, the really strange thing here is that if I enter joebloggs.mydomain.co.uk/rsdev/location/ into my browser (note rsdev is now lowercase), it correctly rewrites as expected. The script newmain.php is in dir RSDEV (uppercase) so if it was going to fail, I would have expected it to fail the other way round with the lowercase rsdev. As you can see, I have [NC] on each line. Is this my mod_rewrite code failing or some other mystical server force keeping me up all night?

  • Refresh page in browser without resubmitting form

    - by Michael
    I'm an ASP.NET developer, and I usually find myself leaving the webpage that I'm working on open in my browser (Chrome is my browser of choice, but this question is relevant for any browser). My workflow typically goes like this: I write code, I rebuild my project in Visual Studio, and then I flip back to my browser with Alt-Tab and hit F5 to refresh the page. This is fine and dandy if a form hasn't been submitted since the page was opened. But if I've been clicking around on ASP.NET form controls, the page has posted form data a number of times, so hitting F5 causes the browser to (sensibly) pop up a confirmation message, e.g., "Confirm Form Resubmission: The page that you're looking for used information that you entered...". Sometimes I do want to resubmit the form, but more often than not, I just want to start over with the page (rather than resubmit form data). The way I usually get around this is to simply add some query string data to the URL so that the browser sees it as a fresh page request, e.g.: page.aspx becomes page.aspx? (or vice-versa). My question is: Is there a better way to quickly request a fresh version of a webpage (and not submit form data) in any of the major browsers? It seems like a no-brainer to me for web development, but maybe I'm missing something. What I'd love to see is something like the last item in this list: F5: refresh page Ctrl-F5: refresh page (and force cache refresh) Alt-F5: request fresh copy of the page without resubmitting the form

  • Context path routing in Tomcat ( service swapping )

    - by jojovilco
    Here is what I would like to achieve: I have a web service A which I want to be able to deploy side by side with other web services of type A - different version(s). For now I assume 2 instances side by side. I need it because the service has a warm up stage, which takes some time to build up stuff from DB and only after it is ready it can start serving requests ... I was thinking to deploy to Tomcat context paths like: "/ServiceA-1.0", "/ServiceA-2.0" and then have a "virtual" context like "/ServiceA" which will point to the desired physical service e.g. "/ServiceA-1.0". So external world will know about ServiceA, but internally, my ServiceA related stack would know about versioned ServiceA url ( there are more components involved but only ServiceA is serving outer world ). When new service is ready, I would just reconfigure the "virtual" context to point to a new service. So far, I was not able to find out how to do this with Tomcat and starting to tkink it is not possible. I found suggestions to place Apache Server in front of Tomcat and do the routing there, but I do not want to enroll another piece of software unless necessary. My questions are: - is this kind of a "virtual" context and routing possible to do with Tomcat? - any other options, wisdom and lessons learned how to achieve this kind of service swapping scenario? Best, Jozef

  • jQuery adding a function to a link question

    - by wali
    Hello all, I have a dynamically created table which in the last <td> there is a hidden <div> which is shown when the user hovers over a link in the <td>. That all works fine but there are several links in the div that I want to fire a function based on the id of the link concat'd with an string captured from a <td> from the parent row. I can capture the the variables I need from the id and <td> but something is wrong with the click function I have created. I monitored the function in FireBug and the function appears to be firing on all of the links instead of the one that is clicked. Here is my working code: function fixLink() { $('a.batchMatchLink').click( function() { var r = $(this).parent().parent().parent().parent().parent(); var x = $(this).attr("id"); var a = $(r).find('td:nth-child(6)').text(); var st = x + "." + a; fireLink(st); } ); } function fireLink(st) { $.ajax({ type: "POST", url: "AjaxWcf.svc/MatchBatch", contentType: "application/json; charset=utf-8", data: st, dataType: "json", success: function(msg) { alert("Entry has been updated"); }, error: AjaxFailed }); Why are all of the links firing?

  • How to map string keys to unique integer IDs?

    - by Marek
    I have some data that comes regularily as a dump from a data souce with a string natural key that is long (up to 60 characters) and not relevant to the end user. I am using this key in a url. This makes urls too long and user unfriendly. I would like to transform the string keys into integers with the following requirements: The source dataset will change over time. The ID should be: non negative integer unique and constant even if the set of input keys changes preferrably reversible back to key (not a strong requirement) The database is rebuilt from scratch every time so I can not remember the already assigned IDs and match the new data set to existing IDs and generate sequential IDs for the added keys. There are currently around 30000 distinct keys and the set is constantly growing. How to implement a function that will map string keys to integer IDs? What I have thought about: 1. Built-in string.GetHashCode: ID(key) = Math.Abs(key.GetHashCode()) is not guaranteed to be unique (not reversible) 1.1 "Re-hashing" the built-in GetHashCode until a unique ID is generated to prevent collisions. existing IDs may change if something colliding is added to the beginning of the input data set 2. a perfect hashing function I am not sure if this can generate constant IDs if the set of inputs changes (not reversible) 3. translate to base 36/64/?? does not shorten the long keys enough What are the other options?

  • JSON onFailure issue

    - by Mikey1980
    I’m having trouble getting a AJAX/JSON function to work correctly. I had this function grabbing value from a drop down box but now I want to use an anchor tag to set it's value. I thought it would be easy to just use the onClick event to pass string to the function I was using for the drop down box but I get the alert in JSON onFailure event even though data gets added to MySQL. I tried removing the alert from onFailure event but then it doesn't add the data. The drop down still continues work work fine, no alerts. (I should note that removing the alert also broke my drop down box) 1st I add an onClick event… <a href="<?php echo Settings::get('app.webroot'); ?>?view=schedule&action=questions" onmouseout="MM_swapImgRestore();" onmouseover="MM_swapImage('bre','','template/images/schedule/bre_f2.gif',1)" onclick="assignCallType('testing')";> 2nd I check main.js.php function assignCallType(type) { alert(type); new Request.JSON({ url: "ajax.php", onSuccess: function(rtndata,txt){ if (rtndata['STATUS'] != 'OK') alert('Status was not okay'); }, onFailure : function () { alert("onFailure") } }).get({ 'action': 'assignCallType', 'call_type': type }); } 3rd Ajax.php: the variable is back in PHP and values get added to MySQL but I get the Alert in the JSON onFailure event if ($_GET['action'] == "assignCallType") { if ($USER->isInsideSales()) { $call_type = $_GET['call_type']; $_SESSION['callinfo']->setCallType($call_type); $_SESSION['callinfo']->save($callid); echo json_encode(array('STATUS'=>'OK')); } else { echo json_encode(array('STATUS'=>'DENIED')); } } Any idea where I am going wrong. The only difference between this and the working drop down is how the function was called, I used onchange="assignCallType(this.value)".

  • How can you pass an object from the form_for helper to a method?

    - by Alex
    So let's say I have a form which is being sent somewhere strange (and by strange we mean, NOT the default route: <% form_for @form_object, :url => {:controller => 'application', :action => 'form_action_thing'} do |f| %> <%= f.text_field :email %> <%= submit_tag 'Login' %> <% end %> Now let's say that we have the method that accepts it. def form_action_thing User.find(????? :email ?????) end My questions are thus: How does can I make the object @form_object available to the receiving method (in this case, form_action_tag)? I've tried params[:form_object], and I've scoured this site and the API, which I have to post below because SO doesn't believe I'm not a spammer (I'm a new member), as well as Googled as many permutations of this idea as I could think of. Nothing. Sorry if I missed something, i'm really trying. How do I address the object, once I've made it accessible to the method? Not params[:form_object], I'm guessing.

  • jQuery AJAX tabs + PHP

    - by ufw
    Hi, seems like I'm stuck with jQuery tabs. I'm trying to pass selected tab name to some php script but is seems like it doesn't get any data. This is how tabs normally work without any response from server side: http://pastebin.com/KBxj7p5k And this is how I try to pass the the current tab name to the server: $(document).ready(function() { $('ul.tabs li').css('cursor', 'pointer'); $('ul.tabs.tabs1 li').click(function(){ var thisClass = this.className.slice(0,2); $('div.t1').hide(); $('div.t2').hide(); $('div.t3').hide(); $('div.t4').hide(); $('div.' + thisClass).show('fast'); $('ul.tabs.tabs1 li').removeClass('tab-current'); $(this).addClass('tab-current'); var name = thisClass; var data = 'name='+name; $.ajax ({ type:"GET", url:"handler.php", data:data, success:function(html) { thisClass.html(html); } }); }); Thanks.
