  • Pagination links do not work after first page

    - by TheStack
    Hello, I am trying to fix this pagination script. It seems when I click on the pagination links [1][2][3][4]or[5] , it doesn't work. It just shows the first page and when clicking on the next numbers nothing happens. I hoping someone can see something in the script that I can not see. The main page looks like this (pagination.php): <?php include_once('generate_pagination.php'); ?> <script type="text/javascript" src="http://ajax.googleapis.com/ajax/libs/jquery/1.4.1/jquery.min.js"></script> <script type="text/javascript" src="jquery_pagination.js"></script> <div id="loading" ></div> <div id="content" data-page="1"></div> <ul id="pagination"> <?php generate_pagination() ?> </ul> <br /> <br /> <a href="#" class="category" id="marketing">Marketing</a> <a href="#" class="category" id="automotive">Automotive</a> <a href="#" class="category" id="sports">Sports</a> Then, generate_pagination.php: <?php function generate_pagination($sql) { include_once('config.php'); $per_page = 3; //Calculating no of pages $result = mysql_query($sql); $count = mysql_fetch_row($result); $pages = ceil($count[0]/$per_page); //Pagination Numbers for($i=1; $i<=$pages; $i++) { echo '<li class="page_numbers" id="'.$i.'">'.$i.'</li>'; } } $ids=$_GET['ids']; generate_pagination("SELECT COUNT(*) FROM explore WHERE category='$ids'"); ?> Here is the jquery file (jquery_pagination.js): $(document).ready(function(){ //Display Loading Image function Display_Load() { $("#loading").fadeIn(900,0); $("#loading").html("<img src='bigLoader.gif' />"); } //Hide Loading Image function Hide_Load() { $("#loading").fadeOut('slow'); }; //Default Starting Page Results $("#pagination li:first").css({'color' : '#FF0084'}).css({'border' : 'none'}); Display_Load(); $("#content").load("pagination_data.php?page=1", Hide_Load()); //Pagination Click $("#pagination li").click(function(){ Display_Load(); //CSS Styles $("#pagination li") .css({'border' : 'solid #dddddd 1px'}) .css({'color' : '#0063DC'}); $(this) .css({'color' : '#FF0084'}) .css({'border' : 'none'}); //Loading Data var pageNum = this.id; $("#content").load("pagination_data.php?page=" + pageNum, function(){ Hide_Load(); $(this).attr('data-page', pageNum); }); }); // Editing below. // Sort content Marketing $("a.category").click(function() { Display_Load(); var this_id = $(this).attr('id'); $.get("pagination.php", { category: this.id }, function(data){ //Load your results into the page var pageNum = $('#content').attr('data-page'); $("#pagination").load('generate_pagination.php?category=' + pageNum +'&ids='+ this_id ); $("#content").load("filter_marketing.php?page=" + pageNum +'&id='+ this_id, Hide_Load()); }); }); }); Lastly, filter_marketing.php (when a user clicks the filter link buttons): <?php include('config.php'); $per_page = 3; if(count($_GET)>0) { if($_GET['page']!=''){ $page=$_GET['page']; } if($_GET['id']!=''){ $id=$_GET['id']; } } $page= ($_GET['page']!='') ? $_GET['page']: false; $id= ($_GET['id']!='') ? $_GET['id']: false; $start = ($page-1)*$per_page; if($page && $id){ $sql = "SELECT * FROM explore WHERE category='$id' ORDER BY category LIMIT $start,$per_page"; } else { die('Error: missing parameters.

  • mysql data being inserted twice via php

    - by Jascha
    I can't for the life of me figure out why this function is causing multiple entries into my database table...

It's possible to define that when starting the class. It's possible to retrive that value inside a function of that class?

  • manipulate variable made up of html before adding it to the dom (new in jQuery 1.4???)

    - by pedalpete
    I thought I had seen this in the first announcement of jQuery 1.4, but can't seem to find anything now. I have a calendar table which is built dynamically from a json ajax response. The table is built in a variable called putHtml. Currently, once the table is added to the DOM, I run a showEvents function which takes each event and adds it to the appropriate cell in the table. Unfortunately, when I have 100 events, that means I am updating the DOM 100 seperate times. Which is getting rather slow. I use the showEvents function to add events dynamically, so it would be really nice if I could just use the same function, and specify to look in the DOM for the cell to add the event to, or look in the variable (assuming I've got it right, and you can actually do this with jQuery). The code I use currenlty is this jQuery('div#calendars').append('putHtml.join('')); for(var e in thisCal.events){ showEvent(thisCal.events[e]); } What I had attempted to do instead was for(var e in thisCal.events){ showEvent(thisCal.events[e],putHtml); } jQuery('div#calendars').append('putHtml.join('')); the showEvents function looks like this function showEvents(event){ var eventDate=event.date; var eventTime=event.time; var eventGroup=event.group; var eventName=event.name; var eventType=event.type; var whereEvent=jQuery('div.a'+eventDate, 'table.'+eventGroup); var putEvent='<div class="event" id="a+'eventDate+'_'+eventTime+'">'+eventName+'</div>' jQuery(whereEvent, 'div#calendar').append(putEvent); if(eventType2){ jQuery(whereEvent, 'div#listings').append(putEvent); } } when attempting to manipulate the variable putHtml before adding to the dom, I was passing putHtml into the showEvent function, so instead of '(whereEvent, 'div#calendar'), I had (whereEvent, putHtml), but that didn't work. of course, the other method to accomplish this would be that when I make each cell, I iterate over the events json, and apply the appropriate html to the cell at the time, but that means repetitively running over the entire json in order to get the event to put in the cell. Is there another/better way to do something like this?

  • How do I splice into a list outside of a macro in Common Lisp?

    - by derefed
    Say I have a function foo: (defun foo (x y &rest args) ...) And I later want to wrap it with a function bar: (defun bar (x &rest args) (foo x 100 args)) Assume bar was then called like this: (bar 50 1 2 3) With this setup, args is a list within the body of bar that holds the trailing parameters, so when I pass it to foo, instead of getting the equivalent of (foo 50 100 1 2 3) I of course get (foo 50 100 '(1 2 3)). If these were macros, I would use `(foo ,x 100 ,@args) within the body of bar to splice args into the function call. ,@ only works inside a backtick-quoted list, however. How can I do this same sort of splicing within a regular function?

  • Use a jquery UI slider to control the resizing of a youtube video.

    - by HV
    Hi, I have a resizable div with the video width and height 100% of the div.

  • Lift session valid ajax callback from a static javascript

    - by ChrisJamesC
    I am currently implementing a graph visualisation tool using lift on the server side and d3 ( a javascript visualisation framework) for all the visualisation. The problem I have is that in the script I want to get session dependent data from the server. So basically, my objective is to write lift-valid ajax callbacks in a static js script. Here is what I tried so far: What I have tried so far If you feel that the best solution is one that I already tried feel free to post a detailed answer telling me how to use it exactly and how it completely solves my problem. REST interface Usually what one would do to get data from a javascript function in lift is to create a REST interface. However this interface will not be linked to any session. This is the solution I got from my previous question: Get json data in d3 from lift snippet Give function as argument of script Another solution would be to give the ajaxcallback as an argument of the main script called to generate my graph. However I expect to have a lot of callbacks and I don't want to have to mess with the arguments of my script. Write the ajax callback in another script using lift and call it from the main script This solution, which is similar to a hidden text input is probably the more likely to work. However it is not elegant and it would mean that I would have to load a lot of scripts on load, which is not really conveniant. Write the whole script in lift and then serve it to the client This solution can be elegant, however my script is very long and I would really prefer that it remainss static. What I want On client side While reviewing the source code of my webpage I found that the callback for an ajaxSelect is: <select onchange="liftAjax.lift_ajaxHandler('F966066257023LYKF4=' + encodeURIComponent(this.value), null, null, null)" name="F96606625703QXTSWU" id="node_delete" class="input"> Moreover, there is a variable containing the state of the page in the end of the webpage: var lift_page = "F96606625700QRXLDO"; So, I am wondering if it is possible to simulate that my ajaxcall is valid using this liftAjax.lift_ajaxHandler function. However I don't know the exact synthax to use. On server side Since I "forged" a request on client side, I would now like to get the request on client side and to dispatch it to the correct function. This is where the LiftRules.dispatch object seems the best solution: when it is called, all the session management has been made (the request is authentified and linked to a session), however I don't know how to write the correct piece of code in the append function. Remark In lift all names of variables are changed to a random string in order to increase the security, I would like to have the same behavior in my application even if that will probably mean that I will have to "give" the javascript these values. However an array of 15 string values is still a better tradeoff than 15 functions as argument of a javascript function.

  • Accessing the calling object into ajax response... (not the ajax call)

    - by Nishchay Sharma
    I have an object of type Application (defined by me). Whenever an object of this type is created, it automatically loads a php file say "start.php" using jquery ajax and assign the response to a div say "Respo". Now what i want is to access the Application object from that Respo div. Unfortunately, i have no clue how to do this... in my ajax call: function Application(options) { ....... var appObj=this; $.ajax({ url:appObj.location, //Already defined success:function(data) { $("#respo").html(data); } }); } Now in my Respo division i want to access that Application object... I tried: alert(this) but it resulted in an object of DOMWindow... i tried editing success function as: function Application(options) { ....... var appObj=this; $.ajax({ url:appObj.location, //Already defined success:function(data) { $("#respo").html("<script type='text/javascript'>var Self="+appObj+"</script>"); $("#respo").html(data); } }); } But i ended nowhere. :( Although if i assign "var Self='nishchay';" then alerting Self from start.php gives nishchay but i am not able to assign the calling object of Application type to the Self variable. It is the only way I cud think of. :\ Please help me... actually my object has some editing functions to control itself - its look and feel and some other options. I want the code loaded by object to control the object itself. Please help me.. Thanks in advance. Nishchay

  • JavaScript Library Design

    - by JSMan2034
    I have a general question about the design of JavaScript Libraries. I am trying to consolidate common methods into one js file so they can be reused by different scripts. I have taken a look at how the JSON library is structured and believe it was a good approach. JSON for Javascript. So they start off creating an instance of the class: if (!this.JSON) { this.JSON = {}; } Then they do this: (function () { if (typeof JSON.stringify !== 'function') { JSON.stringify = function (value, replacer, space) { This is works perfect if you just want to do JSON.[function_name], but what if I want to have a more structured library such that I want: JSON.[subgroup].[function]. How would I structure my JS library in such a way? Any links to resources are greatly appreciated, thanks.

  • is it possible to write a program which prints its own source code utilizing a "sequence-generating-

    - by guest
    is it possible to write a program which prints its own source code utilizing a "sequence-generating-function"? what i call a sequence-generating-function is simply a function which returns a value out of a specific interval (i.e. printable ascii-charecters (32-126)). the point now is, that this generated sequence should be the programs own source-code. as you see, implementing a function which returns an arbitrary sequence is really trivial, but since the returned sequence must contain the implementation of the function itself it is a highly non-trivial task. this is how such a program (and its corresponding output) could look like #include <stdio.h> int fun(int x) { ins1; ins2; ins3; . . . return y; } int main(void) { int i; for ( i=0; i<size of the program; i++ ) { printf("%c", fun(i)); } return 0; } i personally think it is not possible, but since i don't know very much about the underlying matter i posted my thoughts here. i'm really looking forward to hear some opinions!

  • Initializing AngularJS service factory style

    - by wisemanIV
    I have a service that retrieves data via REST. I want to store the resulting data in service level variable for use in multiple controllers. When I put all the REST logic directly into controllers everything works fine but when I attempt to move the retrieval / storing of data into a service the controller is not being updated when the data comes back. I've tried lots of different ways of maintain the binding between service and controller. Controller: myApp.controller('SiteConfigCtrl', ['$scope', '$rootScope', '$route', 'SiteConfigService', function ($scope, $rootScope, $route, SiteConfigService) { $scope.init = function() { console.log("SiteConfigCtrl init"); $scope.site = SiteConfigService.getConfig(); } } ]); Service: myApp.factory('SiteConfigService', ['$http', '$rootScope', '$timeout', 'RESTService', function ($http, $rootScope, $timeout, RESTService) { var siteConfig = {} ; RESTService.get("https://domain/incentiveconfig", function(data) { siteConfig = data; }); return { getConfig:function () { console.debug("SiteConfigService getConfig:"); console.debug(siteConfig); return siteConfig; } }; } ]);

    Dear All, I am migrating my application from 32bit(Windows 2003 Server) to 64bit (Windows 2008 Server R2).I am getting the following while trying to execute a SQL command Encountered ODBC error -1: S1010, 0, [Microsoft][ODBC Driver Manager] Function sequence error . Basically internal function call is SQLExecute() function call. This works perfectly for Windows 2003 Server 32bit. I tried the command execute at the background from the command prompt and it is working. Any help or suggestion would be very much appreciated. I checked the squence of call.We have two consecutive SQLBindParameter function call and then we call SQLExecute. Is this sequence incorrect in case of 64bit? I also checked the return code given by SQLExecute which is 99. Any pointers or suggestions would be very helpful. The above sequence is working fine with 32bit Windows. Thanks in advance. -R

  • Workaround for stopping propagation with live()?

    - by bobsoap
    I've run into the problem that has been addressed here without a workaround: I can't use stopPropagation() on dynamically spawned elements. I've tried creating a condition to exclude a click within the dimensions of the spawned element, but that doesn't seem to work at all. Here is what I got: 1) a large background element ("canvas") that is activated to be "sensitive to clicks on it" by a button 2) the canvas, if activated, catches all clicks on it and spawns a small child form ("child") within it 3) the child is positioned relative to the mouse click position. If the mouse click was on the right half of the canvas, the child will be positioned 200 pixels to the left of that spot. (On the right if the click was in the left half) 4) every new click on the canvas removes the existing child (if any) and spawns a new child at the new position (relative to the click) The problem: Since the spawned child element is on top of the canvas, a click on it counts as a click on the canvas. Even if the child is outside of the boundaries of the canvas, clicking on it will trigger the action as described in 4) again . This shouldn't happen. =========== CODE: The button to activate the canvas: $('a#activate').click(function(event){ event.preventDefault(); canvasActive(); }); I referenced the above to show you that the canvas click-catching is happening in a function. Not sure if this is relevant... This is the function that catches clicks on the canvas: function canvasActive() { $('#canvas').click(function(e){ e.preventDefault(); //get click position relative to canvas posClick = { x : Math.round(e.pageX - $(this).offset().left), y : Math.round(e.pageY - $(this).offset().top) }; //calculate child position if(posClick.x <= $canvas.outerWidth(false)/2) { posChild = { x: posClick.x + 200, //if dot is on the left side of canvas y: posClick.y }; } else { posChild = { x: posClick.x - 600, //if dot is on the right y: posClick.y }; } $(this).append(markup); //markup is just the HTML for the child }); } I left out the unimportant stuff. The question is: How can I prevent a click inside of a spawned child from executing the function? I tried getting the child's dimensions and doing something like "if posClick is within this range, don't do anything" - but I can't seem to get it right. Perhaps someone has come across this dilemma before. Any help is appreciated.

  • A little confused about MVC and where to put a database query

    - by jax
    OK, so my Joomla app is in MVC format. I am still a little confused about where to put certain operations, in the Controller or in the Model. This function below is in the controller, it gets called when &task=remove. Should the database stuff be in the Model? It does not seem to fit there because I have two models editapp (display a single application) and allapps (display all the applications), now which one would I put the delete operation in? /** * Delete an application */ function remove() { global $mainframe; $cid = JRequest::getVar( 'cid', array(), '', 'array' ); $db =& JFactory::getDBO(); //if there are items to delete if(count($cid)){ $cids = implode( ',', $cid ); $query = "DELETE FROM #__myapp_apps WHERE id IN ( $cids )"; $db->setQuery( $query ); if (!$db->query()){ echo "<script> alert('".$db->getErrorMsg()."');window.history.go(-1); </script>\n"; } } $mainframe->redirect( 'index.php?option=' . $option . '&c=apps'); } I am also confused about how the flow works. For example, there is a display() function in the controller that gets called by default. If I pass a task, does the display() function still run or does it go directly to the function name passed by $task?

  • Backbone: Easiest way to maintain reference to 'this' for a Model inside callbacks

    - by Garrett
    var JavascriptHelper = Backbone.Model.extend("JavascriptHelper", {}, // never initialized as an instance { myFn: function() { $('.selector').live('click', function() { this.anotherFn(); // FAIL! }); }, anotherFn: function() { alert('This is never called from myFn()'); } } ); The usual _.bindAll(this, ...) approach won't work here because I am never initializing this model as an instance. Any ideas? Thanks.

  • Visual-C++ Linker Error

    - by LordByron
    I have a class called MODEL in which public static int theMaxFrames resides. The class is defined in its own header file. theMaxFrames is accessed by a class within the MODEL class and by one function, void set_up(), which is also in the MODEL class. The Render.cpp source file contains a function which calls a function in the Direct3D.cpp source file which in turn calls the set_up() function through a MODEL object. This is the only connection between these two source files and theMaxFrames. When I try to compile my code I get the following error messages: 1Direct3D.obj : error LNK2001: unresolved external symbol "public: static int MODEL::theMaxFrames" (?theMaxFrames@MODEL@@2HA) 1Render.obj : error LNK2001: unresolved external symbol "public: static int MODEL::theMaxFrames" (?theMaxFrames@MODEL@@2HA) 1C:\Users\Byron\Documents\Visual Studio 2008\Projects\xFileViewer\Debug\xFileViewer.exe : fatal error LNK1120: 1 unresolved externals
