  • Cross browser div center alignment using CSS

    - by Misha Moroshko
    What is the easiest way to align a div whose position is relative horizontally and vertically using CSS ? The width and the height of the div is unknown, i.e. it should work for every div dimension and in all major browsers. I mean center alignment. I thought to make the horizontal alignment using: margin-left: auto; margin-right: auto; like I did here. Is this a good cross browser solution for horizontal alignment ? How could I do the vertical alignment ?

  • Reading URL Anchor on IE

    - by tominated
    Hi, I've got a page full of links to another page with anchors on the end (like this: index.html#anchor). On the page they point to, I have a script that is supposed to read where the anchor points to in order to display something. On firefox it works perfectly, But I've noticed that IE seems to remove the #anchor from the end of the url, so the script can't grab the text. Is there a way around this, without any server side code?

  • Detect car acceleration in Android app?

    - by Stud33
    I want to incorporate some Accelerometer code into a Android application im working and want to see if this is possible. Basically what I need is for the code to detect car acceleration motion. I am not wanting to determine speed with the code but just distinguish if the phone is in a car and has accelerated motion (Hence the car is moving for the first time). I have gone through many different accelerometer applications to see if this motion produces a viable profile to go off of and it appears it does. Just looking for something that popups a "Hello World" dialog when it detects your in the car and its moving for the first time down the street. Any help would be appreciated and a simple yes or no its possible would work. I would also be interested in compensating anyone that is capable of doing this as well. I need this done like yesterday so please let me know. Thank You, JTW

  • Highstock set different colors for different markers

    - by user1651804
    I am tryting to develop a chart in Highstock where each marker got an individual color. When i push my Data in an Array like this : series.data.push([ parseInt(Math.round(myDate.getTime())), parseInt(Math.round(myDate.getHours())) ]); The Data is shown correctly, but when i try to set the color within each data-object like this, it doesn't work to show points. series.data.push([ { x: parseInt(Math.round(myDate.getTime())), y: parseInt(Math.round(myDate.getHours())), marker:{fillColor: 'red'}} ]); What am i missing? Update: When i inspect it with firebug i can see that the series is set correctly within the chart object. so why does it now show up? :/

  • jEditable - how do I get the edited textfield variable?

    - by Forkrul Assail
    I have a table that I use jEditable with. Saving to the server works, but the callback for refreshing my table element (that I just edited and saved to the server) does not work. /* Apply the jEditable handlers to the table */ $('#example tbody td').editable( '<%= url_for :controller => 'impact_matrix', :action => 'post', :scenario => params[:id] %>', { "callback": function( sValue, y ) { ^ goes missing var aPos = oTable.fnGetPosition( this ); oTable.fnUpdate( sValue, aPos[0], aPos[1] ); }, "submitdata": function ( value, settings ) { temp = value return { "row_id": this.parentNode.getAttribute('id') }; }, sValue (that I point to in the code) - seems to be blank. I do get values for aPos[0] and aPos[1], but not sValue. Could someone please explain to me 'what triggers the callback function?' Or, if I could just see where to get the 'newly edited text' and then just run fnUpdate() on that, I'd be fine. Thanks in advance for your help.

  • Problem with multiple select removing more than 1 option

    - by SoLoGHoST
    Ok, there seems to be a problem with the JS Code for Opera browsers, as it only removes the last option tag that is selected within a multiple select tag, can someone please help me. Here is the HTML for this: <select id="actions_list" name="layouts" multiple style="height: 128px; width: 300px;"> <option value="forum">forum</option> <option value="collapse">collapse</option> <option value="[topic]">[topic]</option> <option value="[board]">[board]</option> </select> Ofcourse it's within a form tag, but there's a ton more code involved with this form, but here is the relevant info for this. Here is the JS that should handle this, but only removes the last selected option in Opera, not sure about other browsers, but it really needs to remove all selected options, not just the last selected option... argg var action_list = document.getElementById("actions_list"); var i = action_list.options.length; while(i--) { if (action_list.options[i].selected) { action_list.remove(i); } } What is wrong with this? I can't figure it out one bit :( Thanks :)

  • Cross Domain Scripting Issues & JSONP

    - by DaveDev
    Our Client requires that we supply Widgits for their site. They want to link to us to get Html & the jQuery required to manipulate the Html and do asynchronous requests. I understand that there are cross-domain security limitations that would prevent this from being a possibility, but that some of those limitations are aleviated by using JSONP as the data transfer format. I'm finding it difficult in finding an explanation of what's possible in the context of what I'm trying to achieve. Could somebody please fill me in?

  • Extract form variable in AJAX response using jquery

    - by Jake
    All, I have a Jquery ajax request calling out a URL. The ajax response I receive is an HTML form with one hidden variable in it. As soon as my ajax request is successful, I would like to retrieve the value of the hidden variabl. How do I do that? Example: html_response for the AJAX call is : <html><head></head><body><form name="frmValues"><input type="hidden" name="priceValue" value="100"></form></body></html> $.ajax({ type: 'GET', url: "/abc/xyz/getName?id="+101, cache: false, dataType: "html", success: function(html_response) { //Extract form variable "priceValue" from html_response //Alert the variable data. } }); Thanks

  • QWidget keyPressEvent override

    - by eaigner
    Hi there, I'm trying for half an eternity now overriding QWidgets keyPressEvent function in QT but it just won't work. I've to say i am new to CPP, but I know ObjC and standard C. My problem looks like this: class QSGameBoard : public QWidget { Q_OBJECT public: QSGameBoard(QWidget *p, int w, int h, QGraphicsScene *s); signals: void keyCaught(QKeyEvent *e); protected: virtual void keyPressEvent(QKeyEvent *event); }; QSGameBoard is my QWidget subclass and i need to override the keyPressEvent and fire a SIGNAL on each event to notify some registered objects. My overridden keyPressEvent in QSGameBoard.cpp looks like this: void QSGameBoard::keyPressEvent(QKeyEvent *event) { printf("\nkey event in board: %i", event->key()); //emit keyCaught(event); } When i change QSGameBoard:: to QWidget:: it receives the events, but i cant emit the signal because the compiler complains about the scope. And if i write it like this the function doesn't get called at all. What's the problem here?

  • How to not allow parts of sortable jquery list to move?

    - by sanpell
    I made a sortable list: <ul> <li class="line"><a href="#" class="food">milk</a></li> <li class="line"><a href="#" class="food">eggs</a></li> <li class="line"><a href="#" class="food">cheese</a></li> </ul> However, I want to make everything with class food not draggable. Since they are links, sometimes when people click them, they accidently reorder the list. Does anyone know how to make just the "food" class items not "draggable"?

  • Google's Geocoder returns wrong country

    - by 6bytes
    Hi I'm using Google's Geocoder to find lat lng coordinates for a given address. var geocoder = new google.maps.Geocoder(); geocoder.geocode( { 'address': address, 'region': 'uk' }, function(results, status) { if(status == google.maps.GeocoderStatus.OK) { lat: results[0].geometry.location.lat(), lng: results[0].geometry.location.lng() }); address variable is taken from an input field. I want to search locations only in UK. I thought that specifying 'region': 'uk' should be enough but it's not. When I type in "Boston" it founds Boston in US and I wanted the one in UK. How to restrict Geocoder to return locations only from one country or maybe from a certain lat lng range? Thanks

  • How to find length of JSON using JSON.parse?

    - by Amol
    I have a Json like this {"0":{"parent_id":1649,"id":"1803","last_update_on":"2010-12-24 07:01:49","message":"dhb;lxd","created_by_id":"21","created_by_name":"Amol Deshpande"}}.

  • OpenLayers: Raise event when map is zoomed or moved by user

    - by David Pfeffer
    I'm using OpenLayers to display OpenStreetMap maps. (Though, I'd assume this should be general enough to work for any map product...) I'm displaying some very sophisticated vector overlays, and the amount and resolution of the features I'm returning from the server via GeoJSON to overlay has proven too much for many computers. What I'd like to do now instead is to only send data befitting the resolution of the current zoom, and fitting the current view port. This should be relatively easy to do using the GetResolution and CalculateBounds methods on the Map object. However, I don't know when to call these methods because I can't find a way to register a function to be called when the user pans the map (changing the view port) or zooms the map (changing the resolution and view port). How can I get a callback when the user pans or zooms the map?

  • Problem using form builder & DOM manipulation in Rails with multiple levels of nested partials

    - by Chris Hart
    I'm having a problem using nested partials with dynamic form builder code (from the "complex form example" code on github) in Rails. I have my top level view "new" (where I attempt to generate the template): <% form_for (@transaction_group) do |txngroup_form| %> <%= txngroup_form.error_messages %> <% content_for :jstemplates do -%> <%= "var transaction='#{generate_template(txngroup_form, :transactions)}'" %> <% end -%> <%= render :partial => 'transaction_group', :locals => { :f => txngroup_form, :txn_group => @transaction_group }%> <% end -%> This renders the transaction_group partial: <div class="content"> <% logger.debug "in partial, class name = " + txn_group.class.name %> <% f.fields_for txn_group.transactions do |txn_form| %> <table id="transactions" class="form"> <tr class="header"><td>Price</td><td>Quantity</td></tr> <%= render :partial => 'transaction', :locals => { :tf => txn_form } %> </table> <% end %> <div>&nbsp;</div><div id="container"> <%= link_to 'Add a transaction', '#transaction', :class => "add_nested_item", :rel => "transactions" %> </div> <div>&nbsp;</div> ... which in turn renders the transaction partial: <tr><td><%= tf.text_field :price, :size => 5 %></td> <td><%= tf.text_field :quantity, :size => 2 %></td></tr> The generate_template code looks like this: def generate_html(form_builder, method, options = {}) options[:object] ||= form_builder.object.class.reflect_on_association(method).klass.new options[:partial] ||= method.to_s.singularize options[:form_builder_local] ||= :f form_builder.fields_for(method, options[:object], :child_index => 'NEW_RECORD') do |f| render(:partial => options[:partial], :locals => { options[:form_builder_local] => f }) end end def generate_template(form_builder, method, options = {}) escape_javascript generate_html(form_builder, method, options) end (Obviously my code is not the most elegant - I was trying to get this nested partial thing worked out first.) My problem is that I get an undefined variable exception from the transaction partial when loading the view: /Users/chris/dev/ss/app/views/transaction_groups/_transaction.html.erb:2:in _run_erb_app47views47transaction_groups47_transaction46html46erb_locals_f_object_transaction' /Users/chris/dev/ss/app/helpers/customers_helper.rb:29:in generate_html' /Users/chris/dev/ss/app/helpers/customers_helper.rb:28:in generate_html' /Users/chris/dev/ss/app/helpers/customers_helper.rb:34:in generate_template' /Users/chris/dev/ss/app/views/transaction_groups/new.html.erb:4:in _run_erb_app47views47transaction_groups47new46html46erb' /Users/chris/dev/ss/app/views/transaction_groups/new.html.erb:3:in _run_erb_app47views47transaction_groups47new46html46erb' /Users/chris/dev/ss/app/views/transaction_groups/new.html.erb:1:in _run_erb_app47views47transaction_groups47new46html46erb' /Users/chris/dev/ss/app/controllers/transaction_groups_controller.rb:17:in new' I'm pretty sure this is because the do loop for form_for hasn't executed yet (?)... I'm not sure that my approach to this problem is the best, but I haven't been able to find a better solution for dynamically adding form partials to the DOM. Basically I need a way to add records to a has_many model dynamically on a nested form. Any recommendations on a way to fix this particular problem or (even better!) a cleaner solution are appreciated. Thanks in advance. Chris

  • Jquery Ajax Call In For Loop Only Runs Once - Possible Issue with Timing & Exit Condition?

    - by Grumps
    Background I'm building a form that uses autocomplete against the EchoNest API. First the users picks an artist, using the Artist Suggest call. Next they select a song but the Song and/Or Artist song search doesn't provide a "wild card" search. It only returns exact matches. So based on the forums they suggest building an array of the songs and using auto complete on the array. I can only get a maximum of 100 responses at a time. I do know based on the initial response the number of songs. My Plan: Wrap the ajax call in a for loop ('runonceloop'). Amend the loop exit condition after the first response with the total number of songs. Challenge I'm having: The 'runonceloop' only completes a singe loop because or at least that's what I believe: The exit condition is satisfied before the first response [1] is received. I've tried to adjust the 'exit condition' and 'counter' such that they are set and and increased at the end of the success block. This seems to lock up my browser. Can someone provide some guidance on this situation?[2] I'd really appreciate it. I also don't think turning async off is a good idea because it locks the browser. Response[1]: { "response": { "status": { "code": "0", "message": "Success", "version": "4.2" }, "start": 0, "total": 121, //Used for "songs": [ { "id": "SOXZYYG127F3E1B7A2", "title": "Karma police" }, { "id": "SOXZABD127F3E1B7A2", "title" : "Creep" } ] } } } Code[2] var songsList = []; function getSongs() { var numsongs = 2; //at least 2 runs. var startindex = 0; runonceloop: //<~~~~Referenced in question for (var j = 0;j >= numsongs;) { console.log('numsongs' + numsongs); $.ajax({ url: "http://developer.echonest.com/api/v4/artist/songs", dataType: "jsonp", data: { results: 100, api_key: "XXXXXXXXXXX", format: "jsonp", name: $("#artist").val(), start: startindex }, success: function (data) { var songs = data.response.songs; numsongs = data.response.total; //modify exit condition for (var i = 0; i < songs.length; i++) { songsList.push(songs[i].title); } j +=100;// increase by 100 to match number of responses. } }); }};

  • TinyMCE is modifying the XHTML 1.0 Strict HTML I input. How can I stop it?

    - by Matt
    The code I want to have saved through TinyMCE is as follows: <object classid="clsid:D27CDB6E-AE6D-11cf-96B8-444553540000" width="550" height="90" id="homepage-banner"> <param name="movie" value="/images/header.swf" /> <param name="wmode" value="transparent" /> <!--[if !IE]>--> <object type="application/x-shockwave-flash" data="/images/header.swf" width="550" height="90"> <param name="wmode" value="transparent" /> <!--<![endif]--> <img src="/images/header.jpg" width="550" height="90" alt="" border="0" /> <!--[if !IE]>--> </object> <!--<![endif]--> </object> Sadly, what I end up with is: <object data="/images/header.swf" height="90" type="application/x-shockwave-flash" width="550"> <param name="id" value="homepage-banner" /> <param name="wmode" value="transparent" /> <param name="src" value="/images/header.swf" /> </object> The purpose of the stripped parts of the code is to provide a fallback image if flash is not available on the client. In my tinyMCE.init({ ... }); I am using verify_html: true and valid_elements is set as per this forum topic whereby all valid XHTML 1.0 Strict elements are allowed. I have checked and the above code does comply with the XHTML 1.0 Strict standard. I have tried just setting verify_html to false but it had no effect. How can TinyMCE be configured to leave my HTML alone?!
