  • How would one rotate an image around itself using Canvas?

    - by Wolfr
    I'm having trouble roating an image around itself using Canvas. Since you can't rotate an image you have to rotate the canvas: if I rotate the canvas by a degree the origin around which I want to rotate changes. I don't get how to track this change. This is my current code: http://pastie.org/669023 And a demo is at http://preview.netlashproject.be/cog/ If you want to give things a shot the zipped up code and image is at http://preview.netlashproject.be/cog/cog.zip

  • change elements' css immediately on scroll event

    - by jedierikb
    I want to change the background color of in-viewport elements (using overflow: scroll) So here was my first attempt: http://jsfiddle.net/2YeZG/ As you see, there is a brief flicker of the previous color before the new color is painted. Others have had similar problems. Following the HTML5 rocks instructions, I tried to introduce requestAnimationFrame to fix this problem to no avail: http://jsfiddle.net/RETbF/ What am I doing wrong here?

  • OpenLayers FramedCloud Autosizing

    - by Kyle
    According to the documentation, I should be able to configure the size of my OpenLayers popup by declaring an OpenLayers.Size object in the FramedCloud constructor: this.popup = new OpenLayers.Popup.FramedCloud('featurePopup', this.options.feature.geometry.getBounds().getCenterLonLat(), new OpenLayers.Size(80, 60), this.template(this.formattedAttrs()), null, true, this.onPopupClose ); Currently the popup that is rendered is autosized no matter what dimensions I use in the constructor. I've tried manually setting the autosizing attribute of the FramedCloud to false as well as manually adjusting the css styling for the popup without achieving the results I need. I checked and found some similar issues in the OpenLayers 2.11 issues list, but I haven't found a workaround. Any ideas?

  • Poll database using jQuery/Ajax

    - by Gav
    Hi guys, I am trying to use jQuery (latest version) & ajax to poll a mysql db every x seconds, post.php does a simple search query on the table and limits to 1 row. (eg SELECT id FROM TABLE LIMIT 1) I've got some other jQuery UI (using v1.8) code that displays some modal/dialog boxes on the screen, simply put if post.php returns something from the db I need to initialise the dialog to pop up onto the screen. I've done all the popup stuff I am just having issues joining all these bits together - i've added some pseudo code of how i expect this to work. Thanks in advance var refreshId = setInterval(function(){ $.ajax({ type: "POST", url: "post.php", data: "", success: function(html){ $("#responsecontainer").html(html); } }); }, 2000 );s /* proposed pseudocode */ if (ajax is successful & returns a db row to #responsecontainer) { show jQueryUI modal (done this bit already fortunately) }

  • jQuery plugin: Validation can't be customized without setting all fields to 'required'?

    - by rasx
    I've spent the day looking at jQuery plugin: Validation by Jörn Zaefferer. I notice that it works fine as long as you call the validate() method without options. In my little squalid world, as soon as I add options, like errorPlacement, I notice that validation ignores form fields that are not marked required. I also notice that many, many demos mark all fields required---or do not pass options. Am I writing about anything familiar here? Or should I astral project to a parallel universe?

  • JQuery Bind click event to appended element with an argument

    - by Gabor Szauer
    Hi guys, I'm trying to populate a ul list with some li elements and give each li element a link that calls the same function with a different argument. However it doesn't seem to work, i've attached the code below, CheckForNewMail is called on document load. Can anyone please help me out? function CheckForNewMail() { ////////////////////////////////////////////////////////////////// // This will be dynamic MailInInbox[0] = new Array("0", "Mail One"); MailInInbox[1] = new Array("12", "Mail Two"); MailInInbox[2] = new Array("32", "Mail Three"); MailInInbox[3] = new Array("5", "Mail Four"); ////////////////////////////////////////////////////////////////////// $('#mail-in-inbox').children().remove(); size = 4; element = $('#mail-in-inbox'); for(i = 0; i < size; ++i) { var link = $('<a href="#" class="inbox-link">'+ MailInInbox[i][1] +'</a>'); link.live('click', function() { LoadMailById(i); }); li = $('<li></li>'); li.append(link); element.append(li); } } function LoadMailById(id) { alert("Button "+ id +" clicked!"); }

  • Is it possible to reference object within the same object?

    - by fudgey
    I've been messing around with jQuery plugin code and I'm trying to put all of my common variables into a single object for easy access. I have included a few examples below on how I've done this, but I'm wondering how others deal with this problem. Lets say I have this var x = function(options){ var defaults = { ulist : $('ul#list'), listLen : $('ul#list').children().length } $.extend(options, defaults); // do other stuff } What I'm trying to do is use the ulist object in as a base, then find the number of li's I guess I could do this: var x = function(options){ var defaults = { ulist : $('ul#list'), listLen : 0 } defaults.listLen = defaults.ulist.children().length; $.extend(options, defaults); // do other stuff } or this: var x = function(options){ var defaults = { ulist : $('ul#list') }; var defaults2 = { listLen : defaults.ulist.children().length } $.extend(defaults, defaults2); $.extend(options, defaults); // do other stuff } The above code samples are just thrown together, and only meant to get the idea across to you. Anyway, is there a better way to do this?

  • JQuery drag and Drop

    - by dremay
    I wish to create an Interface to choose Multiple answers using Drag & Drop rather than CheckBox near to the answers. User can choose two types of answers (Real Answer and a Fake Answer). The User has Two Images (for Real & Fake) on the answer page. User can drag an Image and drop near to the selected answer. It is possible to change the selection by moving the "image and drop over some other answer". I have used a "div formatted with an image" near to all answers, so user can drop the image (ie fake or real image) over this "div". I have used JQuery to move the "image" and drop over the "div". Now I need add the code to the "div" (ie container used to hold the image) to identify which "image is placed over it" ie either "fake or real".

  • Google Maps API v3 - infoWindows all have same content

    - by paulriedel
    Hello, I've been having problems with the infoWindows and Google Maps API v3. Initially, I've ran into the problem that everyone else has of closing infoWindows when opening a new one. I thought to have solved the problem by defining "infowindow" beforehand. Now they close when I click on a new marker, but the content is the same. How should I re-structure my code to make sure the content is the right one each time - and only one infoWindow is open at a given time? Thank you! Paul var allLatLngs = new Array(); var last = 0; var infowindow; function displayResults(start, count){ if(start === undefined){ start = last; } if(count === undefined){ count = 20; } jQuery.each(jsresults, function(index, value) { if(index >= start && index < start+count){ var obj = jQuery.parseJSON(value); $("#textresults").append(index + ": <strong>" + obj.name + "</strong> " + Math.round(obj.distanz*100)/100 + " km entfernt" + "<br/>"); var myLatlng = new google.maps.LatLng(obj.geo_lat, obj.geo_lon); allLatLngs.push(myLatlng); var contentString = '<strong>'+obj.name+'</strong>'; infowindow = new google.maps.InfoWindow({ content: contentString }); var marker = new google.maps.Marker({ position: myLatlng, //title:"Hello World!" }); marker.setMap(map); google.maps.event.addListener(marker, 'click', function() { if (infowindow) { infowindow.close(map,marker); } infowindow.open(map,marker); }); } }); last = start+count;

  • How do I keep users from spoofing data through a form?

    - by Jonathan
    I have a site which has been running for some time now that uses a great deal of user input to build the site. Naturally there are dozens of forms on the site. When building the site, I often used hidden form fields to pass data back to the server so that I know which record to update. an example might be: <input type="hidden" name="id" value="132" /> <input type="text" name="total_price" value="15.02" /> When the form is submitted, these values get passed to the server and I update the records based on the data passed (i.e. the price of record 132 would get changed to 15.02). I recently found out that you can change the attributes and values via something as simple as firebug. So...I open firebug and change the id value to "155" and the price value to "0.00" and then submit the form. Viola! I view product number 155 on the site and it now says that it's $0.00. This concerns me. How can I know which record to update without either a query string (easily modified) or a hidden input element passing the id to the server? And if there's no better way (I've seen literally thousands of websites that pass the data this way), then how would I make it so that if a user changes these values, the data on the server side is not executed (or something similar to solve the issue)? I've thought about encrypting the id and then decrypting it on the other side, but that still doesn't protect me from someone changing it and just happening to get something that matches another id in the database. I've also thought about cookies, but I've heard that those can be manipulated as well. Any ideas? This seems like a HUGE security risk to me.

  • Convert Google results object (pure js) to Python object

    - by colwilson
    So I'm trying to use Google Map suggest API to request place name suggestions. Unfortunately I can't find the docs for this bit. Here is an example URI: http://maps.google.com/maps/suggest?q=lon&cp=3&ll=55.0,-3.5&spn=11.9,1.2&hl=en&gl=uk&v=2 which returns: {suggestion:[{query:"London",... I want to use this in python (2.5). Now in proper JSON there would have been quotations around the keys like so: {"suggestion":[{"query":"London",... and I could have used simplejson or something, but as it is I'm a bit stuck. There are two possible solutions here; either I can get to the API code and find an option to return proper JSON, or I do that in python. Any ideas please.

    How do I print the indicated div (without manually disabling all other content on the page)? I want to avoid a new preview dialog, so crating a new window with this content is not useful... The page contains a couple of tables, one of them contains the div I want to print - the table is styled with visual styles for the web, that should not be shown in print....

  • How can I make an prototype ajax request with an array of values as a parameter?

    - by andresbravog
    i'm trying to make a ajax update in prototype with some values from a multirecordselect that sends a requests like. Parameters: {"action"=>"use_campaign", "campaigns"=> ["27929","27932"] , "advertiser_id"=>"", "controller"=>"admin/reporting", "ad_id"=>""} as you can see the request sends the "campaigns" elements as an array of values, i'm trying to do the same with this js code over prototype 7. // get the campaigns var campaign_ids = {}; var campaigns = $('filter_form').getInputs("hidden","report[campaigns][]"); campaigns.each( function(field) { campaign_ids.push(field.value); }); new Ajax.Updater('ad_filter', '/admin/reporting/use_campaign', { method : 'get', asynchronous : true, evalScripts : true, parameters : { 'advertiser_id' : $('filter_form')['report[advertiser_id]'].value, 'ad_id' : $('filter_form')['report[ad_id]'].value, 'campaigns' : campaign_ids } }); the campaigns_ids is getting the correct info as an array like: [ "27929", "27932" ] but seems that prototype ajax update is sending a request like: http://my_domain/admin/reporting/use_campaign?ad_id=&advertiser_id=&campaigns=27929&campaigns=27932 what sends parameters like: Parameters: {"action"=>"use_campaign", "campaigns"=> "27929" , "advertiser_id"=>"", "controller"=>"admin/reporting", "ad_id"=>""} I also tryed with Object.toJSON(campaign_ids) but i only get an escaped string like Parameters: {"action"=>"use_campaign", "campaigns"=>"[\"27929\",\"27932\"]" , "advertiser_id"=>"", "controller"=>"admin/reporting", "ad_id"=>""} There is anyway to do this as I wish? Thanks for all.
