  • Multi-Part form in Codeigniter

    - by Kevin Brown
    I'm building a survey w/ Codeigniter, and it's getting cumbersomely long...so I want to split it up into sections (about 5). If I want each section to validate, and submit to db after the user clicks "next", what is the best way to do this? I've never made a multi-step process before. Any advice for a noob? :)

  • return false for parent javascript function

    - by jeerose
    $("#purchaser_contact").live('submit', function(){ $.ajax({ type: "POST", url: 'ajax/contactSearch.php', data: ({ fname: $("#fname").val(), lname: $("#lname").val(), city: $("#city").val(), state: $("#state").val() }), success: function(d) { var obj = JSON.parse( d ); if(obj.result != 0){ $("#contactSearch").remove(); $("#button-wrapper").before('<div id="contactSearch">' + obj.result + '</div>'); $("#contactSearch").slideToggle('slow'); //return false from submit!! }); }); I know there are other posts on this but I couldn't figure out how to apply them properly to my situation without making it messy. How do I return false on the submit event to prevent the form from submitting if I'm within the $.ajax and success functions? Thanks.

  • How to run setInterval() on multiple canvases simultaneously?

    - by Alex
    I have a page which has several <canvas> elements. I am passing the canvas ID and an array of data to a function which then grabs the canvas info and passes the data onto a draw() function which in turn processes the given data and draws the results onto the canvas. So far, so good. Example data arrays; $(function() { setup($("#canvas-1"), [[110,110,100], [180,180,50], [220,280,80]]); setup($("#canvas-2"), [[110,110,100], [180,180,50], [220,280,80]]); }); setup function; function setup(canvas, data) { ctx = canvas[0].getContext('2d'); var i = data.length; var dimensions = { w : canvas.innerWidth(), h : canvas.innerHeight() }; draw(dimensions, data, i); } This works perfectly. draw() runs and each canvas is populated. However - I need to animate the canvas. As soon as I replace line 8 of the above example; draw(dimensions, data, i); with setInterval( function() { draw(dimensions, data, i); }, 33 ); It stops working and only draws the last canvas (with the others remaining blank). I'm new to both javascript and canvas so sorry if this is an obvious one, still feeling my way around. Guidance in the right direction much appreciated! Thanks.

  • Work time in fullcalendar [Solution]

    - by Zozo
    Full calendar have no included options to work-time feature (selecting first and last rows in agenda view for any day - where in example company is not working). I managed something like that: viewDisplay: function(view){ $.ajax({ url: 'index.php?r=calendar/Default/worktime', dataType: 'json', success: function(data){ if(view.name=='agendaWeek') selectWorkTime(data, 30, 0, 24, false); else if(view.name=='agendaDay') selectDayWorkTime(data, 30, 0, 24, view, false); } }); } Where index.php?r=calendar/Default/worktime is php file returning json. It looks like that: $arr = array( 'mon' => array('8:00', '17:00'), 'tue' => array('9:00', '15:00'), 'wed' => array('9:30', '19:00'), 'thu' => array('6:00', '14:00'), 'fri' => array('0:00', '24:00'), 'sat' => array('9:00', '14:00'), 'sun' => array() ); foreach ($arr as &$day){ foreach($day as &$hour){ $tmp = explode(':', $hour); $hour = $tmp[0] * 3600 + $tmp[1] * 60; } } print json_encode($arr); and at the end, some functions using for counting and selecting work-time: function selectDayWorkTime(timeArray, slotMinutes, minTime, maxTime, viewObject, showAtHolidays){ var dayname; $('.fc-content').find('.fc-view-agendaWeek').find('.fc-agenda-body') .children('.fc-work-time').remove(); $('.fc-content').find('.fc-view-agendaDay') .find('.fc-work-time-day').removeClass('fc-work-time-day'); switch(viewObject.start.getDay()){ case 1: dayname='mon'; break; case 2: dayname='tue'; break; case 3: dayname='wed'; break; case 4: dayname='thu'; break; case 5: dayname='fri'; break; case 6: dayname='sat'; break; case 0: dayname='sun'; break; } for(var day in timeArray){ if(day == dayname){ if($('.fc-content').find('.fc-view-agendaDay').find('.fc-'+day).attr('class').search('fc-holiday') == -1 || showAtHolidays){ var startBefore = 0; var endBefore = timeArray[day][0] / (60 * slotMinutes) - (minTime * 60) / slotMinutes; var startAfter = timeArray[day][1] / (60 * slotMinutes) - (minTime * 60) / slotMinutes; var endAfter = (maxTime - minTime) * 60 / slotMinutes - 1; for(startBefore; startBefore < endBefore; startBefore++){ $('.fc-view-agendaDay').find('.fc-slot'+startBefore).find('div').addClass('fc-work-time-day'); } for(startAfter; startAfter <= endAfter; startAfter++){ $('.fc-view-agendaDay').find('.fc-slot'+startAfter).find('div').addClass('fc-work-time-day'); } } } } } function selectWorkTime(timeArray, slotMinutes, minTime, maxTime, showAtHolidays){ for(var day in timeArray){ var startBefore = 0; var endBefore = timeArray[day][0] / (60 * slotMinutes) - (minTime * 60) / slotMinutes; var startAfter = timeArray[day][1] / (60 * slotMinutes) - (minTime * 60) / slotMinutes; var endAfter = (maxTime - minTime) * 60 / slotMinutes - 1; if(startBefore > endBefore) endBefore = startBefore; if(startAfter > endAfter) startAfter = endAfter; try{ selectCell(startBefore, endBefore, 'fc-'+day, 'fc-work-time', false, showAtHolidays); selectCell(startAfter, endAfter, 'fc-'+day, 'fc-work-time', true, showAtHolidays); } catch(e){ continue; } } } function selectCell(startRowNo, endRowNo, collClass, cellClass, closeGap, showAtHolidays){ $('.fc-content').find('.fc-view-agendaWeek').find('.fc-agenda-body') .children('.'+cellClass+''+startRowNo+''+collClass).remove(); $('.fc-content').find('.fc-view-agendaDay') .find('.fc-work-time-day').removeClass('fc-work-time-day'); if($('.fc-content').find('.fc-view-agendaWeek').find('.'+collClass).attr('class').search('fc-holiday') == -1 || showAtHolidays){ var width = $('.fc-content').find('.fc-view-agendaWeek') .find('.'+collClass+':last').width(); var height = 0; if(closeGap && (startRowNo != endRowNo)){ height = $('.fc-content').find('.fc-view-agendaWeek') .find('.fc-slot'+ startRowNo).height(); } $('.fc-view-agendaWeek').find('.fc-agenda-body').prepend('<div class="'+cellClass+' ' + ''+cellClass+''+startRowNo+''+collClass+'"></div>'); $('.'+cellClass).width(width - 2); height += $('.fc-content').find('.fc-view-agendaWeek') .find('.fc-slot'+ endRowNo).position().top - $('.fc-content').find('.fc-view-agendaWeek') .find('.fc-slot'+ startRowNo).position().top; $('.'+cellClass+''+startRowNo+''+collClass).height(height); $('.'+cellClass+''+startRowNo+''+collClass) .css('margin-top', $('.fc-content').find('.fc-view-agendaWeek') .find('.fc-slot'+ startRowNo).position().top); $('.'+cellClass+''+startRowNo+''+collClass) .css('margin-left', $('.fc-content').find('.fc-view-agendaWeek') .find('.'+collClass+':last').offset().left - width / 2); } } Don't forget about CSS: .fc-work-time-day{ background-color: yellow; opacity: 0.3; filter: alpha(opacity=30); /* for IE */ } .fc-work-time{ position: absolute; background-color: yellow; z-index:10; margin: 0; padding: 0; text-align: left; z-index: 0; opacity: 0.3; filter: alpha(opacity=30); /* for IE */ } So, I've got some questions about - is the other way to make the same, but no using absolute div's in agendaWeek? And... How can I get in viewDisplay function actual slotMinutes, minTime and maxTime

  • Using jsAnim.js

    - by mark
    I've been trying to set up a basic test animation using jsanim.js and using their example site to set up my html, css and js. However, I just can't figure it out (not a developer...designer!) and there isn't just a simple html, css, js file to download showing how to say animate a DIV left to right. The examples of how the library works are clear but I'm lacking something in the set up and looking at their source on the site is nuts...too much going on in there. Thanks to anyone with experience with jsAnim.js http://www.jsanim.com Best, Mark

  • Google Maps and Json structure

    - by mark
    I found a great script to plot markers on Google Maps. It uses an Json file to laod it. The problem is I don't know what the structure looks like in this case. Can you help? function loadMarkers() { var bounds = map.getBounds(); var zoomLevel = map.getZoom(); $.post("/gmaps/markers/index.php", {zoom: zoomLevel, swLat: bounds.getSouthWest().lat(), swLon: bounds.getSouthWest().lng(), neLat: bounds.getNorthEast().lat(), neLon: bounds.getNorthEast().lng()}, function(data) { processMarkers(data, _smallMarkerSize); }, "json" ); } function processMarkers(webcams, markerSize) { var marker = null; var markersInView = new Array(); var idsInView = new Array(); // Loop through the new webcams for (var i = 0; i < webcams.length; i++) { var idx = markers.indexOf(webcams[i].id); if (idx == -1) { var info_html = "<table class='infowindow'>"; info_html += "<tr><td class='img'>"; info_html += "<img src='" + webcams[i].smallimg + "' /><td>"; info_html += "<td><p><b>" + webcams[i].loc + "</b>"; info_html += "<br /><a href='/webcam/" + webcams[i].url + "' target='_blank'>Show webcam</a></p></td></tr>"; info_html += "</table>"; marker = new WebcamMarker(new GLatLng(webcams[i].latitude, webcams[i].longitude), {image: "" + webcams[i].smallimg + "", height: markerSize, width: markerSize}); marker.myhtml = info_html; map.addOverlay(marker); markersInView[webcams[i].id] = marker; } else { markersInView[webcams[i].id] = markers[webcams[i].id]; } idsInView.push(webcams[i].id); } // Now remove the markers outside of the viewport for (var i = 0; i < webcamids.length; i++) { var idx = markersInView.indexOf(webcamids[i]); if (idx == -1) { marker = markers[webcamids[i]]; map.removeOverlay(marker); } } markers = markersInView; webcamids = idsInView; }

  • How to handle model state errors in ajax-invoked controller action that returns a PartialView

    - by Robert Koritnik
    I have a POST controller action that returns a partial view. Everything seems really easy. but. I load it using $.ajax(), setting type as html. But when my model validation fails I thought I should just throw an error with model state errors. But my reply always returns 500 Server error. How can I report back model state errors without returning Json with whatever result. I would still like to return partial view that I can directly append to some HTML element. Edit I would also like to avoid returning error partial view. This would look like a success on the client. Having the client parse the result to see whether it's an actual success is prone to errors. Designers may change the partial view output and this alone would break the functionality. So I want to throw an exception, but with the correct error message returned to the ajax client.

  • Best way to structure AJAX for a Zend Framework application

    - by John Nall
    Sorry, but there's a lot of outdated and just plain bad information for Zend Framework, since it has changed so much over the years and is so flexible. I thought of having an AJAX module service layer, with controllers and actions that interact with my model. Easy, but not very extensible and would violate DRY. If I change the logistics of some process I'll have to edit the AJAX controllers and the normal controllers. So ideally I would load the exact same actions for both javascript and non-javascript users. I have thought about maybe checking for $_POST['ajax'], if it is set I would load a different (json'y) view for the data. Was wondering how/a good way to do this (front controller plugin I imagine?) or if someone can point me to an UP TO DATE tutorial that describes a really good way for building a larger ajax application. thx

  • Injecting a response value into a textarea to subsequently post

    - by Ashbyrich
    I have multiple notes with class=.note and unique id each inside a div. On click of edit I grab the id, show hidden form #noteditor and hide all notes. I am using the load function to get the response (using codeigniter so url does work) and input result in the editorfrorm Textarea id = upnote... Firebug response looks ok and I have tried to inject into a div and this works fine, BUT getting this injto the text area is causing me some headaches. There is also the chance that i am going around this a convoluted way due to my limited knowledge... Any help or pointers v much appreciated... $(document).ready(function() { $('.edit').click(function(e){ var v=$(this).attr("id"); $(".note").slideUp(); $("#noteditor").slideDown('1000'); $("#upnote" ).load('/notes/my_note/'+v); e.preventDefault(); });

  • jqtouch load content with ajax

    - by ndrizza
    I am loading this page directly inside of jqtouch. First the page shows "Loading..." Then it should execute a GET Request and refresh the content of the div ("tagcloud") as soon as it get's the content from another php file. (I prefer to load the content this way as otherwise jqtouch freezes for 2 seconds until the content is loaded and then animates to the next page.) <?php $link = $_GET['link']; ?> <div id="TagNews"> <div class="toolbar"> <h1>TagNews</h1> <a href="#" class="back">NZZ</a> </div> <div id="tagcloud">Loading...</div> <script type="text/javascript"> $.get("cloudnews2.php?link=<?php echo $link; ?>", function(data){ document.getElementById("tagcloud").innerHTML = data; }); </script> </div> Howewer, the request never gets loaded. The code is working outside of jqtouch. But inside jqtouch the GET Request doesn't work. I can't figure out why. Could you please help me to do this request?

    I have the following script: http://jsfiddle.net/oshirowanen/6SUwR/3/ How do I give the drop down section a dynamic width based on the characters in the dropdown? For example, if "navigation 1" was "this is the first item in the navigation", How do I make the width of the whole dropdown wider automatically, but without affecting the size of the navigation button which causes the dropdown the dropdown when mouseover'ed? Basically, I don't want to text to wrap in the dropdown, but at the same time, I don't want to button for the dropdown to go wider.

  • How to add multiple series in highcharts synchronously

    - by leonlong
    I tried to add multiple series in highcharts synchronously, but the response time is very slow. It took almost 3-5 seconds to display the charts. Here is part of the code. while(chart.series.length>0){ chart.series[0].remove(true); } chart.addSeries(series1); chart.addSeries(series2); chart.addSeries(series3); chart.addSeries(series4); chart.addSeries(series5); When I remain only one addSeries command, it response immediately, so I realized it may be the problem of add multiple series in highcharts synchronously. Not so good at highcharts, so is there anyone could help me about this? Or maybe there is another way to do this, I am much appreciated.

  • Swapping content in a seperate div on hover

    - by Fuego DeBassi
    I feel like this should work: $(".module .one").hover(function() { $("#viewport #one").addClass('red'); }); Basically I am hiding all the .children of "#viewport on load, then when a seperate element is hovered, in this case .module .one I want to change something on the corresponding viewport ID #viewport #one. Basic idea is a variable content window, where when a thumbnail or whatever I put in the modules swaps the content shown in the viewport. Something I am doing wrong? Here is my full code: <script type="text/javascript"> $(document).ready(function() { $(".module .caption").hide(); $("#viewport").children().hide(); $(".module").hover(function() { $(this).find(".caption").slideDown().end().siblings('.module').addClass('under'); },function() { $(this).find(".caption").slideUp().end().siblings('.module').removeClass('under'); }); $(".module .one").hover(function() { $("#viewport #one").addClass('red'); }); }); </script> The bigger hover function in the middle is for some fancy rollover effects that the modules will perform themselves, but for these purposes I just want to figure out why I can't add a Class to a separate element when another is hovered. Would love some help/advice!
