  • run a function when a user clicks on any list element

    - by sova
    This is probably a very common question, but I was unable to find an answer myself; All my list elements call the function setQuery like this onClick="admin_stats.setQuery(this);" rather than [hardcode] add this to every list element, is there a way to simply have it run when a list element is clicked? I'm not very familiar with jQuery Live or binding/unbinding, but I think they would play a role here? Before I reinvent a rather square-looking wheel I thought I might ask =)

  • jquery vote up down, request for some help

    - by Billa
    I want to make some changes in the following piece of code. The demo of the code can be seen here. http://cyberbuff.noadsfree.com/lab/reddit_votes/ The above example shows calculated number of votes (vote ups - votes down). And when you click on any thumbe, it disappears the thumbs and shows the updated votes. I want to make changes that in begining it shows vote up and vote down separately (which are stored in database separately). and after thumb up or down is pressed, it should not remove the thumbs, but it should show the updated vote up and down separatetly. As shown in the image below. Here are pieces of code: Main page having html/CSS and jquery code. http://pastebin.com/RC6dj6N5 vote processng code: http://pastebin.com/heszKyDc PS. I have tried to change by myself but I could not do. Any help will be much appriciated. Thanks.

  • Using HTML Canvas for UI elements?

    - by Tower
    Hi, I have a couple of UI elements such as buttons in my web application. I was going to use CSS3's transitions to animate the transition from one background-image to another. I figured out that it's not possible with the current transitions draft at least. So, I was wondering if it would make sense to use Canvas as the button. I'm sure it can handle events, so, I see no problems here. Are there any?

  • Prevent hash navigation url

    - by Koningh
    I have the following problem: I'm using a slider (coda) to let people navigate trough some 'pages'. The slider uses hash links to navigate to the next page/slide. If a user is at page one (#page1), there is a link which will lead the user to page 2 (#page2) and so on. At the top of the slider the numbers of the pages appear as a link, but only when the page is visited. So if there are six pages and the user navigates from the first to the second and then the third one, there are only three links at the top of the slider (to page one, two and three). The problem is that a user can navigate to page five (or any page actually) without first visiting the pages previous to page five by just using the hash URL and typing the whole link in their address bar. For example if I would type www.mydomain.com/slider/index.php#page5 the slider automatically navigates to the fifth slide/page of the slider and thereby skipping the first four. I want to allow users to navigate to #page5 only if they have visited the first four (So by clicking trough the slides). This means that if they would go to #page5 directly by typing the URL in the address bar, I would like them to be send to the first page (#page1). Does anyone have any idea on solving this?

  • How can I implement "real time" messaging on Google AppEngine?

    - by Freed
    I'm creating a web application on Google AppEngine where I want the user to be notified a quickly as possible after certain events occour. The problem is similar to say a chat server in that I need something happening on one connection (someone is writing a message in a chat room) to propagate to a number of other connections (other people in that chat room gets the message). To get speedy updates from the server to the client I'm planning on using long polling with XmlHttpRequest, hoping that AppEngine won't interfere other than possibly restriing the timeout. The real problem however is efficient notification between connections on AppEngine. Is there any support for this type of cross connection notification on AppEngine that does not involve busy-waiting? The only tools I can think of to do this at all is either using the data storage (slow) or memcache (unreliable), and none of them would let me avoid busy-waiting. Note: I know about XMPP support on AppEngine. It's related, but I want a browser based solution, sending messages to the users by XMPP is not an option.

  • Why this button doesn't cause triple postback?

    - by focus
    We have developed a page with a asp.net and debugging it accidentally we have discovered on our page button with the next code on onclik attribute onclick="__doPostBack('ctl00$FormPlace$m_userTaskMarkAsUnreadButton',''); __doPostBack('ctl00$FormPlace$m_userTaskMarkAsUnreadButton','');WebForm_DoPostBackWithOptions(new WebForm_PostBackOptions("ctl00$FormPlace$m_userTaskMarkAsUnreadButton", "", true, "", "", false, false))" It seems that the button do three postbacks but when we click it only cause on postback. With this code seems that de button will cause three postbacks!! We have try it with Internet Explorer and Firefox and the button only cause on postback always. Are browsers who avoid that the button do three postback ? Or Is Asp.net server who avoid the three postback? We don't understand why the button behaves correctly if onclick attribute has three call to do Postbacks. Thanks

    - by Alex
    I know its been asked many times already but no one could come up with solution so far. The idea is to have one form separated into few steps and validate each step on next click of the button. I know jquery validation plugin is offering quite complicated way of doing it with accordion but can anyone come up with a simple solution something like var stepOne = { rules: { fieldname1: "required", fieldname2: "required", } } $("form").validate(stepOne); //onclick hope someone could suggest the best way of doing it. Thanks.

  • multiple ajax request to action in asp.net mvc

    - by persian Dev
    I am developing an asp.net mvc application and have ajax calls on my page. Here is a form which I load by ajax call to page : The form is located in a partial view <div id="CreateCultureArea"> <% using (Ajax.BeginForm("CreateCulture", "Admin", new AjaxOptions() { OnSuccess = "handleCreateCulture" })) { %> ..... <% } %> </div> The following script is located in a view $('.CreateCulture').live('click', function (e) { e.preventDefault(); var idval = this.id; $.ajax({ url: "/Admin/CreateCulture", dataType: 'html', data: { id: idval }, success: function (mydata) { $("#CultureContentArea").empty(); $("#CultureContentArea").empty().hide().append(mydata).fadeIn(2000); $("form").removeData("validator"); $("form").removeData("unobtrusiveValidation"); $.validator.unobtrusive.parse("form"); }, type: "GET" }); return false; }) </script> When users click on a link with CreateCulture class, the form is loaded to page. But as I saw the requests in firebug, it calls the action multiple times. I read similar posts like mine on stackoverflow.com and most of them suggested removing repetitive "jquery.unobtrusive-ajax.min.js" calss in page, but as I saw the output page I only see on link to the "jquery.unobtrusive-ajax.min.js" script.

  • Image swaping with click on <tr>

    - by Jonny Sooter
    I've edited this piece of code from the Data Tables Plugin witch makes a tr click able and pops open another tr with details from the clicked tr. This piece of code is the event listener for opening and closing. When "details" are open the img should be images/details_close.png and they are closed the img should be images/details_open.png and have a swap occurring when it opens and closes when clicked. What is happening is there is no swap going on when its open or closed I still only get the "details_open.png". I don't knoe if I'm just not selecting the img tag properly or whats going on. Link to project: http://www2.kent.k12.wa.us/ksd/it/www/mobile/elementary.html $('#example tbody').on('click', 'td', function (e) { var myImage = $(this).find("img"); var nTr = $(this).parents('tr')[0]; if ( oTable.fnIsOpen(nTr) ) { /* This row is already open - close it */ myImage.src = "images/details_open.png"; oTable.fnClose( nTr ); } else { /* Open this row */ myImage.src = "images/details_close.png"; oTable.fnOpen( nTr, fnFormatDetails(oTable, nTr), 'details' ); } } );

  • Jquery find first visible element after horizontal scroll

    - by lolo flores
    I’m new (only two weeks old) in Jquery, so please bear with me. I know that a very similar question was asked some time ago but I do not know how to adapt the answer to my problem. I have a very wide multicolumn layout something like this: | aaaa | bbbb | cccc | … | | aaaa | b | cc | … | | aaa | cccc | ddd | … | The code looks like: <div id="container"> <p>aaaaaaaaaaa</p> <p>bbbbb</p> <p>ccccccccccc</p> <p>dddddddddd</p> ... <p>xxxxxx</p> </div> There is no vertical scrolling and the container width is set in such a way that only two columns are shown. The user scrolls left or right to see the relevant text. What I want is to get the position currently on display, store it (maybe in a cookie) and retrieve it the next time the user opens the page. I think that I need a way of finding out what paragraph is currently the left-top most, but other suggestions are very welcome. Any ideas? btw: this is an internal project, so Mozilla only :-) Thanks Lolo

  • How can chunks be allocated in a node.js stream in object mode all at once?

    - by Quentin Engles
    I can see how buffers, and strings can be sent as chunks, but I'm having a problem thinking about how streams can be dealt when working in object mode. Say I have a byte stream from an http request message. I want to take that message, parse, and then transform it into one big object. I already know how to parse the message. What I'm wondering is if the message is big so it has many chunks, but I want to make one object for the output how can I make sure the data event waits for the whole thing? Is this just a matter of not using the push method until the chunked data has finished being sent? That would then restrict the stream data output to a smaller object which I think I'm fine with for now. As an added condition the larger data will be reduced in size after the the transform.

  • jQuery: preventdefault does not work

    - by Kent Miller
    I somehow cannot achieve that the a-tag looses its default action when clicking it: <a href="#" class="button dismiss">dismiss</a> $(document).ready(function() { $('.dismiss').click(function(e) { e.preventDefault(); $('#output').empty(); $('#MyUploadForm .button').show(); }); }); When I click the button, the browser window scrolls to the top. What is wrong here?

  • Codeigniter: Retrieving data on button click with Ajax

    - by OllyTenerife
    I have a simple webpage which generates a random quote from my database upon refreshing the page. I wish to implement some AJAX and JQuery in order to generate quotes via the button rather than having to refresh the page. I have done some research but I am not sure how to implement this in Codeigniter. My current code is below... Page controller: public function index() { $this->load->model('quote_model', '', TRUE); $data['quotes'] = $this->quote_model->getRandom(); $this->load->view('home', $data); } The view: <?php include ('layout/header.php'); ?> <div class="container-fluid"> <div class="row"> <div class="col-md-4 quote-holder"> <img src="application/assets/alan1.jpg" alt="..." class="img-circle img-responsive"> <br> <blockquote class="text-center"> <p><?php echo $quotes[0]['quote']; ?></p> <footer class="text-center"><?php echo $quotes[0]['character_name']; ?> in <cite title="Source Title"><?php echo $quotes[0]['series_name']; ?></cite></footer> </blockquote> <button type="button" class="btn btn-default center-block">Generate quote</button> </div> </div> <?php include ('layout/footer.php'); ?> Here is the function in the model I am retrieving the data from: function getRandom() { $query = $this->db->query(" SELECT * FROM quotes, characters, series WHERE quotes.series_id = series.series_id AND quotes.character_id = characters.character_id ORDER BY rand() LIMIT 1 "); return $query->result_array(); } Should I simply be using something like this? $("button").click(function(){ $.get( "Page/index", function( data ) { //output data to page element... } });

  • Need some explanation about MS Ajax using PageMethods

    - by Ahmed Said
    I have a project that uses PageMethods to call functions on the server. The server functions (written in C#) return the values as array of strings, without doing any kind of serialization and in the client side (from Js) the accessing of the return values is by using static variable called arguments. I found that sometimes for some users (cases are not repro) sometimes an exception occured "WebServiceFailedException the server method 'Foo' returned invalid data. the 'd' property is missing from JSON." Some searching on google I found that people are serializing the return values using DataContractJsonSerializer class and in js accessing the return value using one of the callback function Example: function OnRequestComplete(result, userContext, methodName) { var Person = eval('(' + result + ')'); alert(Person.Forename); alert(Person.Surname); } So is the first technique is correct? or what?

  • Dragged div change places with destination

    - by Cudos
    Hi. Maybe a bit complex to explain. I have a grid with 9 images 100 x 100 px like this (each number symbolize a picture): 1 2 3 4 5 6 7 8 9 What I want is that the user can drag and drop e.g. 9 over 1 and they change places like this: 9 2 3 4 5 6 7 8 1 Sortables from jquery UI will not work since their solution is using floats. That will "push" all the boxes to the right or left e.g.: 9 1 2 3 4 5 6 7 8 thanks in advance.

  • RegEx expression or jQuery selector to NOT match "external" links in href

    - by TrueBlueAussie
    I have a jQuery plugin that overrides link behavior, to allow Ajax loading of page content. Simple enough with a delegated event like $(document).on('click','a', function(){});. but I only want it to apply to links that are not like these ones (Ajax loading is not applicable to them, so links like these need to behave normally): target="_blank" // New browser window href="#..." // Bookmark link (page is already loaded). href="afs://..." // AFS file access. href="cid://..." // Content identifiers for MIME body part. href="file://..." // Specifies the address of a file from the locally accessible drive. href="ftp://..." // Uses Internet File Transfer Protocol (FTP) to retrieve a file. href="http://..." // The most commonly used access method. href="https://..." // Provide some level of security of transmission href="mailto://..." // Opens an email program. href="mid://..." // The message identifier for email. href="news://..." // Usenet newsgroup. href="x-exec://..." // Executable program. href="http://AnythingNotHere.com" // External links Sample code: $(document).on('click', 'a:not([target="_blank"])', function(){ var $this = $(this); if ('some additional check of href'){ // Do ajax load and stop default behaviour return false; } // allow link to work normally }); Q: Is there a way to easily detect all "local links" that would only navigate within the current website? excluding all the variations mentioned above. Note: This is for an MVC 5 Razor website, so absolute site URLs are unlikely to occur.

  • Slow Response in checkbox using JQuery

    - by Dean
    Hi to all. I'm trying to optimize a website. The flow is i tried to query a certain table and all of its data entry in a page(w/ toolbars), work fine. When i tried to edit the page the problem is when i click the checkbox button i have to wait 2-5sec just by clicking it. I limit the viewing of entry to 5 only but the response on checkbox doesn't change. The tables have 100 entries in them. function checkAccess(celDiv,id) { var celValue = $(celDiv).html(); if (celValue==1) $(celDiv).html("<input type='checkbox' value='"+$(celDiv).html()+"' checked disabled>") else $(celDiv).html("<input type='checkbox' value='"+$(celDiv).html()+"' disabled>") $(celDiv).click ( function() { $('input',this).each( function(){ tr_idx = $('#detFlex1 tbody tr').index($(this).parent().parent().parent()); td_idx = $('#detFlex1 tbody tr:eq('+tr_idx+') td').index($(this).parent().parent()); td_last = 13; for(var td=td_idx+1; td<=td_last;td++) { if ($(this).attr('checked') == true) { df[0].rows[tr_idx].cell[td_idx] = 1;//index[1] = Full Access if (td_idx==3) { df[0].rows[tr_idx].cell[td] = 1; } df[0].rows[tr_idx].cell[2] = 1; if (td_idx > 3) { df[0].rows[tr_idx].cell[2] = 1; } } else { df[0].rows[tr_idx].cell[td_idx] = 0;//index[0] = With Access if (td_idx==2) { df[0].rows[tr_idx].cell[td] = 0; } else if (td_idx==3) { df[0].rows[tr_idx].cell[td] = 0; } if (td_idx > 3) { df[0].rows[tr_idx].cell[3] = 0; } } } $('#detFlex1').flexAddData(df[0]); $('.toolbar a[title=Edit Item]').trigger('click'); }); } ); } I've thought that the problem is this above code. Could anyone help me simplify this code.?
