  • regexp for detect that the url doesn´t end with an extension

    - by devnieL
    Hello. I'm using this regular expression for detect if an url ends with a jpg : var exp = /(\b(https?|ftp|file):\/\/[-A-Z0-9+&@#\/%?=~_|!:,.;]*[-A-Z0-9+&@#\/%=~_|]*^\.jpg)/ig; it detects the url : e.g. http://www.blabla.com/sdsd.jpg but now i want to detect that the url doesn't ends with an jpg extension, i try with this : var exp = /(\b(https?|ftp|file):\/\/[-A-Z0-9+&@#\/%?=~_|!:,.;]*[-A-Z0-9+&@#\/%=~_|]*[^\.jpg]\b)/ig; but only get http://www.blabla.com/sdsd then i used this : var exp = /(\b(https?|ftp|file):\/\/[-A-Z0-9+&@#\/%?=~_|!:,.;]*[-A-Z0-9+&@#\/%=~_|]*[^\.jpg]$)/ig; it works if the url is alone, but dont work if the text is e.g. : http://www.blabla.com/sdsd.jpg text

  • Check if window has focus

    - by user2536244
    I need to check if the user has windows on focus, I'm currently doing this: var isonfocus=true; window.onblur = function(){ isonfocus=false; } window.onfocus = function(){ isonfocus=true; } And whenever I need to check if the user has the windows on focus I just do if(isonfocus==true). Problem: if the user loses focus before the page loads, even if I do if(isonfocus==true) it will return true, even though the window is not on focus, and defining the var to false var isonfocus=false; will do the reverse. Can someone help me? Thanks.

  • How to remove the upper right close button

    - by tahdhaze09
    I need to kill the close 'x' button at the top of a jQuery UI modal dialog box. I have a modal that opens with an OK button that redirects to the site. The site behind the modal is in an iframe. When the user agrees to the statement in the dialog box and clicks the 'OK' button, it redirects to the site that is outside the iframe. If the user clicks on the 'x', it goes to the iframe site, which I do not want to have happen. I need the modal to work as a one-way to the site it goes to. It basically forces the user to accept the user agreement. I would post code, but its an intranet site. Thanks everyone for your help! EDIT: This site is a government intranet portal, not a commercial site. So the goal is NOT to trap a user into the site, but rather to let the user know that the use of this site is restricted and to make sure you understand and accept the user agreement or you cannot use the site.

  • CSS variable width element to fill in space

    - by Gary Volland
    In a form, I would like the input:text to fill the remain space after the label to the form is left and right justified. The label have number of characters so I can't set a fixed width on the label. Code example: <fieldset> <legend>User Info</legend> <p><label>First Name :</label><input type="text"...></p> <p><label>Last Name : </label><input type="text"...></p> <p><label>Completed Email Address :</label><input type="text"...></p> </fieldset> How can I style the input to fill the remaining space after the text. Thanks.

  • Destroying a record via RJS TemplateError (Called ID for nil...)

    - by bgadoci
    I am trying to destroy a record in my table via RJS and having some trouble. I have successfully implemented this before so can't quite understand what is not working here. Here is the setup: I am trying to allow a user of my app to select an answer from another user as the 'winning' answer to their question. Much like StackOverflow does. I am calling this selected answer 'winner'. class Winner < ActiveRecord::Base belongs_to :site belongs_to :user belongs_to :question validates_uniqueness_of :user_id, :scope => [:question_id] end I'll spare you the reverse has_many associations but I believe they are correct (I am using has_many with the validation as I might want to allow for multiple later). Also, think of site like an answer to the question. My link calling the destroy action of the WinnersController is located in the /views/winners/_winner.html.erb and has the following code: <% div_for winner do %> Selected <br/> <%=link_to_remote "Destroy", :url => winner, :method => :delete %> <% end %> This partial is being called by another partial `/views/sites/_site.html.erb and is located in this code block: <% if site.winners.blank? %> <% remote_form_for [site, Winner.new] do |f| %> <%= f.hidden_field :question_id, :value => @question.id %> <%= f.hidden_field :winner, :value => "1" %> <%= submit_tag "Select This Answer" %> Make sure you unselect any previously selected answers. <% end %> <% else %> <div id="winner_<%= site.id %>" class="votes"> <%= render :partial => site.winners%> </div> <% end %> <div id="winner_<%= site.id %>" class="votes"> </div> And the /views/sites/_site.html.erb partial is being called in the /views/questions/show.html.erb file. My WinnersController#destroy action is the following: def destroy @winner = Winner.find(params[:id]) @winner.destroy respond_to do |format| format.html { redirect_to Question.find(params[:post_id]) } format.js end end And my /views/winners/destroy.js.rjs code is the following: page[dom_id(@winner)].visual_effect :fade I am getting the following error and not really sure where I am going wrong: Processing WinnersController#destroy (for 127.0.0.1 at 2010-05-30 16:05:48) [DELETE] Parameters: {"authenticity_token"=>"nn1Wwr2PZiS2jLgCZQDLidkntwbGzayEoHWwR087AfE=", "id"=>"24", "_"=>""} Rendering winners/destroy ActionView::TemplateError (Called id for nil, which would mistakenly be 4 -- if you really wanted the id of nil, use object_id) on line #1 of app/views/winners/destroy.js.rjs: 1: page[dom_id(@winner)].visual_effect :fade app/views/winners/destroy.js.rjs:1:in `_run_rjs_app47views47winners47destroy46js46rjs' app/views/winners/destroy.js.rjs:1:in `_run_rjs_app47views47winners47destroy46js46rjs' Rendered rescues/_trace (137.1ms) Rendered rescues/_request_and_response (0.3ms) Rendering rescues/layout (internal_server_error)

  • iPad doesn't trigger resize event going from vertical to horizontal?

    - by dclowd9901
    Has anyone noticed this behavior? I'm trying to write a script that will trigger upon a resize. It works fine on normal browsers, works fine on iPhone, but on iPad, will only trigger going from horizontal to vertical viewport, not vice versa. Here's the code: $(window).resize( function() { var agent=navigator.userAgent.toLowerCase(); var is_iphone = ((agent.indexOf('iphone') != -1)); var is_ipad = ((agent.indexOf('ipad') != -1)); if(is_iphone || is_ipad){ location.reload(true); } else { /* Do stuff. */ }; });

  • KeyboardState.pressed is always true after .prompt or alert - Why?

    - by Yenza
    As the title says, I have tried THREEx and Stemkovskis standalone KeyboardState.js , and neither of them seems to update properly. This is my code: m_vKeyboard = new THREEx.KeyboardState(); // m_vKeyboard.update(); // if using stemkovskis if (m_vKeyboard.pressed("F")) { alert("And now it is always true!"); } you click the F key once, release it; alert window pops up, click OK, it pops up again for all eternity. How come?

    - by Jones
    I have a swf object embedded into a web page. Without having access to the source code of the swf file, how can I find the methods/properties that are exposed? For example... alert(document.getElementById('swfObject').id); ...returns a pop-up of "swfObject". And this... document.getElementById('swfObject').someMethod(); ...executes someMethod. Thanks.

  • Is there a sexier way to write this jQuery selector?

    - by Bears will eat you
    I want to select all the children of the body element before element with id foo (which is a child of body). Since it doesn't look like there are :before() or :after() selectors, I've got it working like this: $('body > :first').nextUntil('#foo').andSelf(); but it seems kludgy. Could this be done with fewer function calls, or more efficiently? Maybe something akin to $('body > *:before(#foo)') ?

Any help would be greatly appreciated.

  • use JSON variable in jQuery dynamically

    - by user1644123
    I have two DIVs, #placeholder AND #imageLoad. When the user clicks on a particular thumb its larger version (thumb2) should then appear in #imageLoad DIV. Here is the jQuery that needs to be fixed: $.getJSON('jsonFile.json', function(data) { var output="<ul>"; for (var i in data.items) { output+="<li><img src=images/items/" + data.items[i].thumb + ".jpg></li>"; } output+="</ul>"; document.getElementById("placeholder").innerHTML=output; }); //This is wrong!! Not working.. $('li').on({ mouseenter: function() { document.getElementById("imageLoad").innerHTML="<img src=images/items/" + data.items[i].thumb2 + ".jpg>"; } }); Here is the external JSON file below (jsonFile.json): {"items":[ { "id":"1", "thumb":"01_sm", "thumb2":"01_md" }, { "id":"2", "thumb":"02_sm", "thumb2":"02_md" } ]}

  • Can you explain this odd behavior with dragging items into nested sortables?

    - by RDL
    I have the following setup: A sortable list where one of the <li> has a table with lists in each cell. All of the lists are sortable with each other. Draggable items that can be added to any of the sortables Issue: When adding a draggable item ('drag 1', 'drag 2', 'drag 3') to one of the lists in the horizontal lists (table of lists) it duplicates the draggable when dropped. Sometimes it will create both copies in the same list or one in the item list and one in the column list. Here is a demo: http://jsfiddle.net/MQTgA/ Question: How do I prevent the second item being created when dropping the draggable?

  • 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?

  • Change a select list display value upon selecting description

    - by eli
    Hello, I would like a select list that does the following: When the select list is open, display the list of descriptions. When the user selects an item, the select list will close an only the value will be displayed. The reason for this is to conserve space as the values will be much shorter. I'm hoping that there's an answer in jQuery. Thanks.

  • How to add values to a JSON object?

    - by Damiano
    Hello everybody, I have created an array with: var msg = new Array(); then, I have a function that add values to this array, this function is: function add(time, user, text){ var message = [time, user, text]; if (msg.length >= 50) msg.shift(); msg.push(message); } As you can see, if the array has 50 or more elements I remove the first with .shift(). Then I add an array as element. Ok, the code works perfectly, but now I have to loop the msg array to create a JSON obj. The JSON object should has this format: var obj = [ {'time' : time, 'user' : user, 'text' : text}, {'time' : time, 'user' : user, 'text' : text}, {'time' : time, 'user' : user, 'text' : text} ] I mean...i have to loop msg array and then store all the values inside the JSON object. I do not know how to "concatenate" the element of the array inside json obj. Could you help me? Thank you very much in advance!

  • Jsonp cross-domain ajax

    - by Guillaume le Floch
    I'm working on an application which use ajax call to get html from the server. When I run it on the server, everything works fine. But when I'm running on a localhost, I've a 'Access-Control-Allow-Origin' error. I looked arround and it seems like using jsonp could be the solution. So, my ajax call looks like that: $.ajax({ url: url, dataType: 'jsonp', crossDomain: true, type: 'GET', success: function(data){ // should put the data in a div }, error: function(){ //do some stuff with errors } }); I get html from the server, but I always have this error: Uncaught SyntaxError: Unexpected token < Is there a way to wrap the jsonp response in html? Thanks!

  • IE 8 specifying background-color changes element behavior

    - by Mateo
    I have an absolutely positioned div on which I am trying to trigger mouseenter and mouseleave events. In IE8/7 with the background-color of the div left unspecified (so that it defaults to transparent), the mouseenter/leave events are not firing when the cursor crosses the div's boundary, only somewhere in the middle of the div and when the cursor is over any text within the div. When I attempt to debug the problem by adding a background color to the div (e.g. background-color: green), the problem magically goes away. The div's box model is honored perfectly and mouseenter/leave fire as when expected. It's only when the div's background color is left unspecified (or even explicitly set to transparent) that it doesn't behave correctly. Any ideas? Googling for this IE bug/quirk is coming up with nothing.
