  • How to get the handler position

    - by Geetha
    Hi All, I am using the following files to create a slider. <link type="text/css" href="CSS/demos.css" rel="stylesheet" /> <link type="text/css" href="CSS/jquery-ui.css" rel="stylesheet" /> <script type="text/javascript" src="js/jquery.ui.core.js"></script> <script type="text/javascript" src="js/jquery.ui.slider.js"></script> Problem: i want to get the index of the handler, when i drag it to some other position. Ex: initial position of the handler: l-------------------------------- value = 0 After dragging it some other position ----------------------l---------- value = ? Code: var endTime = document.mediaPlayer.SelectionEnd; $("#slider-constraints").slider({ animate: true, max: endTime, range: $R(0, endTime), value: 1, enforceConstraints: false, start: function(event, index) { alert(index.value); } }); window.setInterval(function() { $('#slider-constraints').slider("value", document.mediaPlayer.currentPosition); }, 4000);

  • jquery animating different img widths

    - by romeozor
    Hi there, I've been searching for an answer for a long time with no avail, so it's time to ask. I'm trying to use .animate() to change the size of an image once clicked. The first state of the image would be a thumbnail size, which would animate to the image's original size, then to a thumbnail again. The problem is, not all the images have the same "original" size so I need a way to tell one generic function to switch to the current image's original size. This is my current code which loads on $(window).load: $('img[class=resize]').click(function (){ if ($(this).width() != 150) { $(this).animate({width: '150px'}, 400); } else { $(this).animate({width: ''}, 400); } }); Now this obviously doesn't work the way I want it, because .animate() thinks when I say width: '' I want to make the width = 0. Any suggestions how I should go about this?

  • jQuery Tooltip plugin error

    - by hd
    i have written this code to apply 'jQuery Tooltip plugin' to ajax loaded elements. i mean the row i want to show tooltip on its mouseover is loaded into page by ajax. here's the code: $("[id^=pane]").delegate("[id^=comm]","mouseover",function() { $(this).tooltip({ // each trashcan image works as a trigger tip: "#tooltip", // custom positioning position: "center right", // move tooltip a little bit to the right offset: [0, 15], // there is no delay when the mouse is moved away from the trigger delay: 0 }).dynamic({ bottom: { direction: "down", bounce: true } }); }); the tooltip is shown when mouseover but firebug report this error: "$(this).tooltip({tip: "#tooltip", position: "center right", offset: [0, 15], delay: 0}).dynamic is not a function" is it because of using $(this) ???

  • C socket programming: recv / select not seeing sent messages

    - by Fantastic Fourier
    Hey guys, I had some questions, about socket programming for client-server using TCP/IP. I am using select() to recv(), which works fine when client send() messages to server, but not the other way around. The send() returns positive (and reasonable) numbers of bytes sent by server but I know that the nubmer of bytes "sent" really means "sent out of the socket", not "sent and was received by the client." The select() function seems to work fine. So given that, my guess is that it's the send() function that is giving me the problem. Probably the address of client in send() is not correct. But when I compared address.sin_addr.s_addrmember (it's an unsigned long int) of struct sockaddr_in from recv() and send() of server, they are identical. So I am kind of lost as to what could be wrong?

  • Jquery Exclude a Selector?

    - by Wes
    I've got a form that I clear on focus. I've selected the whole form and it works great except that the submit button goes blank when I click it. how can I exclude my input of input#submit from the following code? $(".wpcf7-form input, .wpcf7-form textarea").focus(function() { if( this.value == this.defaultValue ) { this.value = ""; $(this).addClass('filled'); } }).blur(function() { if( !this.value.length ) { this.value = this.defaultValue; $(this).removeClass('filled'); } });

  • $.ajax working with Firefox, not IE

    - by Isamtron
    Hello, I have a jQuery code to allow users to login using a lightbox (http://colorpowered.com/colorbox/) and immediately start downloading files, without being redirected or having the page reloaded. It's perfectly working in Firefox but Internet Explorer keeps showing the login box until I reload the page :( <? if (!$this->session->userdata('user_logged_in')): ?> <script type="text/javascript"> $(document).ready(function() { $('a[href^="/link/"]').click(function(event){ var status = $.ajax({ url: "/status", async: false }).responseText; if (status != 'USER_LOGGED_IN') { $.fn.colorbox({href:"/login"}); event.preventDefault(); } }); }); </script> <? endif ?> Your help would be greatly appreciated.

  • Dynamically generating high performance functions in clojure

    - by mikera
    I'm trying to use Clojure to dynamically generate functions that can be applied to large volumes of data - i.e. a requirement is that the functions be compiled to bytecode in order to execute fast, but their specification is not known until run time. e.g. suppose I specify functions with a simple DSL like: (def my-spec [:add [:multiply 2 :param0] 3]) I would like to create a function compile-spec such that: (compile-spec my-spec) Would return a compiled function of one parameter x that returns 2x+3. What is the best way to do this in Clojure?

  • Problems using the Razor model when creating my knockout ViewModel

    - by Emil Kantis
    I'm having problems with using the Model in a javascript call when setting up my knockout VM.. @model List<AdminGui.Models.Domain> <script src="http://ajax.aspnetcdn.com/ajax/knockout/knockout-2.2.1.js" type="text/javascript"></script> <script type="text/javascript"> function ViewModel() { var self = this; self.domains = ko.observableArray( ko.utils.arrayMap(@Model, function(item) { return new Domain(item.guid, item.description, item.namespaces); })); } I get a syntax error on @Model in the ko.utils.arrayMap call. I suspect it might be my Razor-fu that is lacking... :)

  • static, define, and const in C

    - by yCalleecharan
    Hi, I've read that static variables are used inside function when one doesn't want the variable value to change/initialize each time the function is called. But what about defining a variable static in the main program before "main" e.g. #include <stdio.h> static double m = 30000; int main(void) { value = m * 2 + 3; } Here the variable m has a constant value that won't get modified later in the main program. In the same line of thought what difference does it make to have these instead of using the static definition: const double m = 30000; or #define m 30000 //m or M and then making sure here to use double operations in the main code so as to convert m to the right data type. Thanks a lot...

  • jQuery click event not working when mouse moves from one div to another with button held down

    - by Acorn
    I've made a page that uses jQuery to allow you to place <div>s on the page based on your mouse coordinates when you click. The page And here's the javascript: $('document').ready(function() { $("#canvas").click(function(e){ var x = e.pageX - this.offsetLeft; var y = e.pageY - this.offsetTop; $(document.createElement('div')).css({'left':x + 'px', 'top':y + 'px'}).addClass('tile').appendTo('#canvas'); }); }); I've found that if you mousedown in the div#canvas and mouseup with your pointer over a placed <div> (or vice versa) then a new <div> doesn't get placed. Why is this?

  • Lua: Random: Percentage

    - by jargl
    I'm creating a game and currently have to deal with some math.randomness. As I'm not that strong in Lua, how do you think Can you make an algorithm that uses math.random with a given percentage? I mean a function like this: function randomChance( chance ) -- Magic happens here -- Return either 0 or 1 based on the results of math.random end randomChance( 50 ) -- Like a 50-50 chance of "winning", should result in something like math.random( 1, 2 ) == 1 (?) randomChance(20) -- 20% chance to result in a 1 randomChance(0) -- Result always is 0 However I have no clue how to go on, and I completely suck at algorithms I hope you understood my bad explanation of what I'm trying to accomplish

    - by Adam
    ArgumentError: Error #2025: The supplied DisplayObject must be a child of the caller. so i have a function that runs in state1 and has a while(myCanvas.rawChildren.numChildren > 0){ myCanvas.rawChildren.removeChildAt(0); } //this code is definitely the problem.... I can move to state2, but when I move back to state1 i get the error. why? the function that has the while loop only runs when something is searched in state1, so why is it running when coming back from state2?

  • get_called_class hack not working with eval-code.

    - by Ekampp
    Hi there. I am using a ge_called_class hack for allowing late static binding in php version 5.2 (found here). I have the following in my code: # db_record.php $ac = "ForumThread"; $objects = $ac::find("all"); This will not work in php 5.2 for some reason, so I have done this: # db_record.php $ac = "ForumThread"; eval("\$objects = {$ac}::find('all');"); This on the other hand will not work with the get_called_class function. I get an error that the file function can't read the evaled section of code. So how do I solve this problem? Best regards.

  • Override default javascript functionality with jQuery

    - by deth4uall
    I am trying to overwrite a JavaScript on change event in the below code with jQuery however I believe that the inline JavaScript is taking priority over the jQuery functionality declared. Essentially I am trying to have an AJAX version of my site which includes an additional JavaScript file. I need this functionality to still work without the additional AJAX version, but I am not sure as to whether I should include it in the main JavaScript file or leave it inline like it is right now. Any suggestions and information regarding them would be greatly appreciated! Thanks! <form action="/cityhall/villages/" method="post" name="submit_village"> <select name="village" onchange="document.submit_village.submit();"> <option value=""></option> </select> </form> I am trying to use the jQuery Form Plugin to submit the posts to the PHP to handle the requests as follows: var bank_load_options = { target: '#content', beforeSubmit: showRequest, success: showResponse }; $('form.get_pages').livequery(function(){ $(this).ajaxForm(bank_load_options); return false; }); I modified the code as following: <form action="/cityhall/villages/" method="post" id="submit_village" name="submit_village"> <select name="village" class="get_pages" rel="submit_village"> <option value=""></option> </select> </form> <script> # main JavaScript $('.get_pages').live('change',function(e){ var submit_page = $(this).attr('rel'); $("#"+submit_page).submit(); }); # ajax JavaScript var bank_load_options = { target: '#content', beforeSubmit: showRequest, success: showResponse }; $('.get_pages').live('change',function(){ var submit_page = $(this).attr('rel'); $("#"+submit_page).ajaxForm(get_pages_load_options); return false; }); </script> However now it only runs every other option when I change it.

  • Can't call method in model table class using Doctrine with Zend Framework

    - by Jeremy Hicks
    I'm using Doctrine with Zend Framework. For my model, I'm using a base class, the regular class (which extends the base class), and a table class. In my table class, I've created a method which does a query for records with a specific value for one of the fields in my model. When I try and call this method from my controller, I get an error message saying, "Message: Unknown method Doctrine_Table::getCreditPurchases". Is there something else I need to do to call functions in my table class? Here is my code: class Model_CreditTable extends Doctrine_Table { /** * Returns an instance of this class. * * @return object Model_CreditTable */ public static function getInstance() { return Doctrine_Core::getTable('Model_Credit'); } public function getCreditPurchases($id) { $q = $this->createQuery('c') ->where('c.buyer_id = ?', $id); return $q->fetchArray(); } } // And then in my controller method I have... $this->view->credits = Doctrine_Core::getTable('Model_Credit')->getCreditPurchases($ns->id);

  • Coldfusion CFC creation taking a variable amout of time to execute.

    - by Bazza
    I've been doing some logging of object creation times in our open account process in production. Periodically, initializing an object would take way longer than expected. By initializing I mean calling it's init() and passing a couple of arguments that may be simple variables or objects. e.g. <cfset validateObj = createObject("component", "compExample").init( productionMode = VARIABLES.productionMode, ipWhiteListed = isWhiteListed, ipLocatorObj = VARIABLES.ipLocatorObj ) /> Thats all that happens in init() methods. Generally the execution time would be 0ms, but at random times I might get 3 or 3.5 seconds. This is not specific to one particular server or to our generally busy period. It appears to be quite random. One thought was that these templates were being evicted from our template cache as they are not especially frequently used, although I checked cfstat on a number of servers and the max CP/Sec is -1. Running CF 8,0,1 Has anybody else ever come across this?

  • Have to put files in static_dir but need to read them afterwards

    - by SanjamX
    I just started using google app engine. In order to use templates, I'm using jinja2. I want to add images dynamically after I set the width and height of the img tag. I used PIL in order to read the image size and put the one I want. However when I open the image with PIL, I need it not to be in a static_dir and to put the image in the img tag, I need it to be in the static_dir. As a testing solution I've copied the folder to see if I get results and I did. But as you can see having each image saved twice is kind of bad.

  • Modulation of adding new Strings -> Method calls.

    - by guesswork
    If I have a program that does the following: if(input=='abc'){do x} if(input=='def'){do y} In the future, I may want to add another piece of code like so: if(input=='ghy'){do x} As you can see, I am adding a new 'if' statement for a different conditional BUT using the SAME function X. The code in future has potential to have lots of different IF statements (or switches) all of which are comparing a string vs a string and then performing a function. Considering the future expansion, I was wondering if there is a possible 'neater', 'modular' way of achieving the same results. It's a shame I can't combine the String with a Method call in a hashtable (String, method) in Java. That way I could just store any new procedures inside a hashtable and grab the relevant method for that String. Any ideas? Thank you
