  • jquery show / hide div on click even in a slideshow?

    - by KnockKnockWhosThere
    Is it possible to combine a slideshow and show / hide div functionality? My html structure is below, and basically, I'm trying to get the tabs a links to open up the div with the corresponding class if a user clicks on it. If a user doesn't click on it, it should still just cycle through each image. So, if the images are rotating, and I click on <a class="t2"> then would open. The thing is, it's unknown how many divs / tabs there will be, but they'll always be named t{n}. <div id="tab-content"> <div class="t1">content</div> <div class="t2">lorem ipsum</div> <div class="t3">knock knock</div> </div> <div id="nav"> <div id="tabs"> <ul> <li class="t1"><a class="t1" href="#">tab 1</a></li> <li class="t2"><a class="t2" href="#">tab 2</a></li> <li class="t3"><a class="t3" href="#">tab 3</a></li> </ul> </div> </div>

  • How to refresh jQuery Selector Value after an execution?

    - by Devyn
    Hi, I have like this. $(document).ready(function() { var $clickable_pieces = $('.chess_piece').parent(); $($clickable_pieces).addClass('selectee'); // add selectee class var $selectee = $('.chess_square.selectee'); // wait for click $($selectee).bind('click',function(){ $('.chess_square.selected').removeClass('selected'); $(this).addClass('selected'); { ........... } }); I initially inject 'selectee' class to all div which has 'chess_piece' class then I select DIVs with that class $('.chess_square.selectee'). <div id="clickable"> <div id="div1" class="chess_square"> </div> <div id="div2" class="chess_square selectee"> <div id="sub1" class="chess_piece queen"></div> </div> <div id="div3" class="chess_square"> </div> </div> There are two type of DIV element with class named 'chess_square selectee' and 'chess_square' which doesn't meant to be clickable. I move around Sub DIV of 'rps_square selectee' from DIV2 to DIV1 and add and remove classes to be exactly same like this. The meaning is Queen Piece is moved from Div2 to Div1. <div id="div1" class="chess_square selectee"> <div id="sub1" class="chess_piece queen"></div> </div> <div id="div2" class="chess_square"> </div> <div id="div3" class="chess_square"> </div> However, the problem is jQuery doesn't update var $selectee = $('.rps_square.selectee');. Even though I changed class names, DIV1 is not clickable and DIV2 is still clickable. By the way, I've used jQuery UI selectable but doesn't refresh either.

  • Wasteful Ajax Page Loading

    - by Matt Dawdy
    I've started a new job, and the portion of the project I'm working has a very odd structure. Every pages is a .Net aspx page, and it loads just fine, but nothing is really done at load time. Everything is really loaded from a jquery document.onready handler. What is even more...interesting...is that the onready handler calls some ajax calls that drop entire .aspx pages into divs on the page, but first it strips out several parts of the the returned page. This is the "magic" script the previous programmer ran on all the returned html from his ajax calls: function CleanupResponseText(responseText, uniqueName) { responseText = responseText.replace("theForm.submit();", "SubmitSubForm(theForm, $(theForm).parent());"); responseText = responseText.replace(new RegExp("theForm", "g"), uniqueName); responseText = responseText.replace(new RegExp("doPostBack", "g"), "doPostBack" + uniqueName); return responseText; } He then intercepts any kind of form postback and runs his own form submission function: function SubmitSubForm(form, container) { //ShowLoading(container); $(form).ajaxSubmit( { url: $(form).attr("action"), success: function(responseText) { $(container).html(CleanupResponseText(responseText, form.id)); $("form", container).css("margin-top", "0").css("padding-top", "0"); //HideLoading(container); } } ); } Am I way offbase in thinking that this is less than optimal? I mean, how does a browser take out the html and head and other tags that don't have anything to do with what you are really trying to drop into that div? Also, he's returning things like asp:gridview controls, and the associate viewstate, which can be quite large if his dataset is big. Has anyone seen this before?

  • Creating and appending a big DOM with javascript - most optimized way?

    - by fenderplayer
    I use the following code to append a big dom on a mobile browser (webkit): 1. while(someIndex--) // someIndex ranges from 10 to possibly 1000 2. { 3. var html01 = ['<div class="test">', someVal,'</div>', 4. '<div><p>', someTxt.txt1, someTxt.txt2, '</p></div>', 5. // lots of html snippets interspersed with variables 6. // on average ~40 to 50 elements in this array 7. ].join(''); 8. var fragment = document.createDocumentFragment(), 9. div = fragment.appendChild(document.createElement('div')); 10. div.appendChild(jQuery(html01)[0]); 11. jQuery('#screen1').append(fragment); 12. } //end while loop 13. // similarly i create 'html02' till 'html15' to append in other screen divs Is there a better or faster way to do the above? Do you see any problems with the code? I am a little worried about line 10 where i wrap in jquery and then take it out.

  • Safari specific scroll bar issue in legacy code

    - by user1237169
    I am trying to debug an issue that is occurring specifically in Safari. On a few pages of a web application, the content is larger than the frame and a scroll bar appears on the right but when the scroll bar moves up or down the content does not scroll with it. So you can "scroll" the scroll bar but the content itself was inaccessible even though the scroll bar was mobile. The issue only occurs in the "Multi-Process Windows" debug mode option but not in the "Single-Process Windows" option. The scroll bar works perfectly fine in Firefox, IE, and Chrome, just not in Safari. Because there's a lot of legacy code, I'm not quite sure exactly what the actual content is and which specific html elements are relevant. From what I can tell there's an Iframe element, html element, body element, div element, iframe element html element, body element and finally some divs. edit Does it matter if some of the elements within the <iframe> have the attribute scrolling="no"? I see this on a few of the elements within iframe but my coworker reassures me they don't matter.

  • How to make a div extend when floating it?

    - by cjmcjm
    I'm trying to create a bar with a dynamic horizontal width. The backgrounds are transparent pngs so they can't overlap. I have one for the left side, one to repeat-x across the dynamic width middle and then another bg for the right. Here is kinda what I have so far... .bar{ width: 100%; } .left{ width: 50px; height: 50px; float: left; } .mid{ height: 50px; float: left; } .right{ width: 50px; height: 50px; float: right; } <div class="bar"> <div class="left"></div> <div class="mid"></div> <div class="right"></div> </div> So the main problem is extending the .mid all the way across to meet the right, width: 100% doesn't work. The other problems is what can I do if I have content that needs to overlap the .left and .mid divs? Set up another div and use z-index? Thanks so much!

  • When I Add <DIV> Bottom Scroll Bar Appears, Even Though It Is Not Greater Than The Page Width

    - by Clay Dempsey
    I have searched for this with no answer. My page loads up perfectly when I load the header, navigation and then center image...all 3 different divs. However I have more I need to add and the div tags change the size of the page even though the css I'm using isn't larger than the page. I have no idea what is happening. Here's the code page where everything is fine: http://www.thehdmgroup.com/midwaymissionary/test.php When I add the below div tag with the below css I get a bottom scrollbar on the page and I don't know why. Can someone please explain it to me? #middleTextBox1 { position: absolute; top:507px; left:172px; width:180px; height:180px; background-color:#411b42; border: 1px solid #434343; padding:10px; color: #FFFFFF; font-size: 10px; font-family: Arial, Helvetica, sans-serif; } <div id="middleTextBox1"> <h3 align="center">Mission:</h3> Words </div> I really have no idea why this is happening, could someone please help me out?

    I have 3 divs that I would like to display as table cells: <div class="field"> <div class="row"> <label for="name">Subdomain</label> <input type="text" id="name" name="name"> <div class="subdomain-base ">test</div> </div> </div> This is the CSS that I am using: body{ font-size: 13px; } .field { width:450px; display: table; } .row { display: table-row; width: 100%; } .row > * { display: table-cell; border: 1px solid red; } label { width: 125px; height: 18px; } input { max-width: none; min-width: 0; overflow: auto; height: 18px; width: 100%; } .subdomain-base { height: 18px; width: 1px; } .subdomain-base { color: blue; font-size: 13px; } It works perfectly in Firefox 24: However, it has a height problem in Chrome 30 (latest): I have been trying all sorts of things to fix the problem with Chrome, but it seems like nothing works.

  • JQuery Delegate and using traveral options in function

    - by Brian
    I am having trouble figuring out how to use the JQuery delegate function to do what I require. Basically, I need to allow users to add Panels (i.e. divs) to a form dynamically by selecting a button. Then when a user clicks a button within a given Panel, I want to be able to to something to that Panel (like change the color in this example). Unfortunately, it seems that references to the JQuery traversing functions don't work in this instance. Can anybody explain how to achieve this effect? Is there anyway to bind a different delegate to the each panel as its added. $('.addPanels').delegate('*', 'click', function() { $(this).parent.css('background-color', 'black'); $('.placeholder').append('Add item'); }); <div class="addPanels"> <div class="panel"> <a href="#" class="addLink">Add item</a> text</div> <div class="placeholder"/> </div> </div>

  • jquery find() - how to exclude certain descendants, and their children?

    - by jammypeach
    I have markup similar to this: <div class='wrapper plugin'> //some content <div class='child-wrapper plugin'> //some more content <div> <ul> <li><div class='cliky'>clicky!</div></li> </ul> </div> </div> <div class='cliky'>clicky!</div> </div> I need to be able to select the first .clicky div only, not any .clicky divs inside a .plugin > .plugin div. The wrapper has .plugin class too - might seem counter-intuitive so another way to view it is this: I want to get the .clicky children of a given .plugin div, but not .plugin .plugin .clicky. Here's the problem - the depth of each .clicky element (or indeed, the number of them) is unknown and variable in relation to the wrappers. One could be immediately below the first wrapper, or inside 10 <ul>s. I've tried selectors like: $('.wrapper').find('.clicky').not('.plugin > .clicky'); But they still selected child .clicky. How would I be able to filter out .plugin and any children of .plugin from my selector before using find()?

  • How do I make an iframe 100% height of a containing div in Firefox?

    - by David
    I'm having some trouble figuring out how to extend an iframe to 100% of it's container element in Firefox and IE (it works fine in Chrome). From searching around, it makes sense that there has to be a width specified on the containing div (and possibly body and html as well). However, I have done that, and the iframe is still not extending. Do all of the parent divs have to have a specified width and position for this to work, or just the containing parent? Any fix for this would be greatly appreciated! Here's what I have: <!DOCTYPE html> <html> <head> <style> html, body {margin:0; padding:0; height:100%} #container {width: 1000px; min-height: 550px; position: relative} #smallContainer {position:relative} /*no width specified*/ #iframeContainer {height: 100%; position: relative} #iframe {height: 100%; width: 100%; display: block} </style> </head> <body> <div id="container"> <div id="smallContainer"> <div id="iframeContainer"> <iframe id="iframe" src="foo.com"></iframe> </div> </div> </div> </body> </html>

  • Pushing elements into array as copy

    In prototypejs, why does the following code remove the matching divs from the #test div? What confuses me is that this happens when they are being inserted in the #droparea, and not when they are being pushed in the array. <div id="test"> <div class="foo" id="22.1234"> 1 </div> <div class="foo" id="22.1235"> 2 </div> <div class="foo" id="53.2345"> 3 </div> <div class="foo" id="53.2346"> 4 </div> </div> <div id="droparea"> </div> js var elArray = []; var els = $('test').select('.foo'); els.each(function(x){ if(x.id.split('.')[0] == 22){ elArray.push(x); } }); elArray.each(function(y){ $('droparea').insert({ bottom: y }); });

  • Setting up padding for websites in mobile devices

    - by ambrelasweb
    I had finished this website a while ago but something happened to it and I've now spent all day fixing it and getting it back from scratch as my backup wasn't correctly done. I don't quite understand what it's doing as I've done this technique on many other websites with no troubles, maybe I've looked at this website too long? Here is the website. I'm wanting to put some space on the left and right hand side, however I dont just have one container as I was needing the dark grey bar at 100% of the screen and always under the banner no matter where it was. So there are 4 "containing" divs that I want to have the space. I've placed soem CSS3 media queries in but now I'm getting a gap to the right. I was thinking it was because my background mages are going all the way across but they set at 100% so I'm just not understanding whats going on. It's somethign simple, I'm not seeing it right now.. This is what I have for the media queries /* Smartphones (portrait and landscape) ----------- */ @media only screen and (min-device-width : 320px) and (max-device-width : 480px) { #header, #banner, #main, #footer-widget-area { padding: 0 2em 0 2em; } } This is what t looks like on my iPhone Any advice is helpful and appreciated.

  • Why does my DIV clip its child DIV when jQuery moves it in IE?

    - by Ben Saufley
    I have two divs, both with position:absolute;, one inside the other. The parent isn't in a place where it can be set as position:relative without an extra layer of complexity (there are a lot of other elements around it that I'd have to account for to put it where it needs to be, which is at the very top of the page, over everything). The child element is made to stick off the bottom of the parent. In Chrome, Safari, Firefox, it all works splendidly. In IE, it works until jQuery moves the parent element - at which point the parent element clips the child, so you can barely see the top of the child. I feel like I've read about this, about IE clipping child elements, but I can't seem to find an answer that applies to my case. It's pretty simple, basically: <div id="parent" style="position:absolute;top:0;left:0;"> [content] <div id="tab" style="position:absolute;bottom:-30px;left:0;width:64px;height:32px;background-image:(...);"></div> </div> <script> $(document).ready( function() { $("#tab").click(function() { $("#parent").animate({"top":"-50px"},300); }); }); </script>

  • CSS positioning div above another div when not in that order in the HTML

    - by devmode
    Given a template where the HTML cannot be modified because of other requirements, how is it possible to display a div above another div when they are not in that order in the HTML and both divs contain data that could produce a varying height and width. HTML: <div id="wrapper"     <div id="firstDiv"         Content to be below in this situation     </div     <div id="secondDiv"         Content to be above in this situation     </div </div Other elements Hopefully it is obvious that the desired result is: Content to be above in this situation Content to be below in this situation Other elements When the dimensions are fixed it easy to position them where needed, but I need some ideas for when the content is variable. For the sake of this scenario, please just consider the width to be 100% on both. Edit: A CSS solution is the most ideal solution. Thank you for the Javascript options mentioned. Without getting too wordy about what or why (or who) ... I am specifically looking for a CSS only solution (and it will probably have to be met with other solutions if that doesn't pan out). One more ... there are other elements following this. A good suggestion was mentioned given the limited scenario I demonstrated -- given that it might be the best answer, but I am looking to also make sure elements following this aren't impacted.

  • what is the best way to optimize my json on an asp.net-mvc site

    - by ooo
    i am currently using jqgrid on an asp.net mvc site and we have a pretty slow network (internal application) and it seems to be taking the grid a long time to load (the issue is both network as well as parsing, rendering) I am trying to determine how to minimized what i send over to the client to make it as fast as possible. Here is a simplified view of my controller action to load data into the grid: [AcceptVerbs(HttpVerbs.Get)] public ActionResult GridData1(GridData args) { var paginatedData = applications.GridPaginate(args.page ?? 1, args.rows ?? 10, i => new { i.Id, Name = "<div class='showDescription' id= '" + i.id+ "'>" + i.Name + "</div>", MyValue = GetImageUrl(_map, i.value, "star"), ExternalId = string.Format("<a href=\"{0}\" target=\"_blank\">{1}</a>", Url.Action("Link", "Order", new { id = i.id }), i.Id), i.Target, i.Owner, EndDate = i.EndDate, Updated = "<div class='showView' aitId= '" + i.AitId + "'>" + GetImage(i.EndDateColumn, "star") + "</div>", }) return Json(paginatedData); } So i am building up a json data (i have about 200 records of the above) and sending it back to the GUI to put in the jqgrid. The one thing i can thihk of is Repeated data. In some of the json fields i am appending HTML on top of the raw "data". This is the same HTML on every record. It seems like it would be more efficient if i could just send the data and "append" the HTML around it on the client side. Is this possible? Then i would just be sending the actual data over the wire and have the client side add on the rest of the HTML tags (the divs, etc) be put together. Also, if there are any other suggestions on how i can minimize the size of my messages, that would be great. I guess at some point these solution will increase the client side load but it may be worth it to cut down on network traffic.

  • How can I bind multiple Jquery UI Slider with "year" Select?

    - by arthur_br
    Hi, I'm trying to render sliders instead of select components. Each page has several select components marked with class='jqselect' and all of them will have decreasing year values (some years may be missing). Eg. a select may have values [2010, 2009, 2006, 2005, 2004]. I have tried binding it both following the examples in the jQuery UI doc (but ignoring the missing years) and using selectToUISlider by filamentgroup (http://www.filamentgroup.com/lab/update_jquery_ui_slider_from_a_select_element_now_with_aria_support//). None of them work. Here is what I've done so far: Binding selects with following slider container divs: $('#content div.jqslider').slider({ animate: true, min: $(this).prev().children().last().val(), max: $(this).prev().children().first().val(), slide: function(event, ui) { var select = $(this).prev(); select.val($(this).slider('option', 'value')); console.log($(this).slider('option', 'value')); //debug } }); This renders the slider, but console logs values from 0 to 100 and selects obviously does not change with the event. Using selectToUISlider: $('#content select.jqselect').selectToUISlider(); This does not even render the slider, throwing an error 'b is undefined' in jquery-min.js (line 30, v1.4.2). If I pass the identifier of only one of the sliders, it is rendered but very buggy. Please, I'm stucked in the by two days and any help is much appreciated. Regards, Arthur

  • [ASP.NET MVC] Run ajax scripts on page with navigating with ajax?

    - by Oskar Kjellin
    I got a bit of an issue in my ASP.NET MVC project. I have a chat div in the bottom right corner (like facebook), and of course I do not want this to reload when navigating to all my navigation is ajax. The problem I am facing is that I use the following code on the top of the view page: <script type="text/javascript"> $(document).ready(function() { $('#divTS').hide(); $('a#showTS').click(function() { $('#divTS').slideToggle(400); return false; }); }); </script> The problem is that this code is only loaded with ajax and does not seem to fire? I would like to run all scripts in the newly loaded view, just as if I hadn't navigated with ajax. I cannot put this in the site.master as it only loads once and then probably the divs I am trying to hide doesn't exist. Is there a good way to run scripts in the ajax-loaded div?

  • Why does setting the margin on a div not affect the position of child content?

    - by DanM
    I'd like to understand a little more clearly how css margins work with divs and child content. If I try this... <div style="clear: both; margin-top: 2em;"> <input type="submit" value="Save" /> </div> ...the Save button is right up against the User Role (margin fail): If I change it to this... <div style="clear: both;"> <input style="margin-top: 2em;" type="submit" value="Save" /> </div> ...there is a gap between the Save button and the User Role (margin win): Questions: Can someone explain what I'm observing? Why doesn't putting a margin on the div cause the input to move down? Why must I put the margin on the input itself? There must be some fundamental law of css I am not grasping.

  • Why does animate not work for the first few 'selections' of my next button?

    - by Josiah
    I'll just start right off the bat and say I'm fairly new to JQuery, so if you see some glaring issues with my code....let me know what I'm doing wrong! Either way, I've been working on a script to fade divs in and out using the z-index and animate. It "works" after about 2-3 clicks, but the first two clicks do not fade or animate as I was hoping....why is that? I'll just throw javascript up here, but if you need/want more code, just let me know. Thanks! $(document).ready(function() { //Slide rotation/movement variables var first = $('#main div.slide:first').attr('title'); var last = $('#main div.slide').length; //Needed for the next/prev buttons var next; //Set the first div to the front, and variable for first div var $active = $('#main div.slide[title='+first+']'); //Hide the links until the div is hovered over and take them away when mouse leaves $('#main').children('a').hide(); $('#main').mouseenter(function() { $('#main').children('a').fadeIn(750); }).mouseleave(function() { $('#main').children('a').fadeOut(750); }); $active.css('z-index', '4'); $('#main #next').click(function() { if ((next = parseInt($active.attr('title')) + 1) > last) { next = 1; } $active.css('z-index', '0').stop().animate({opacity: 0}, 1000); $active = $('#main div[title='+next+']').css('z-index', '4').stop().animate({opacity : 1}, 1000); }); });

  • Is there a way to check if a div has the same class as an ancestor in jQuery?

    - by T.R.
    I'm looking to dynamically highlight a tab, if it represents the current page. I have: <style> #tabs li{bg-color: white;} body.Page1 #tabs .Page1, body.Page2 #tabs .Page2, body.Page3 #tabs .Page3{bg-color: orange;} </style> <body class="Page1 ADifferentClass"> <ul id="tabs"> <li class="Page1 SomeClass"> <li class="Page2 SomeOtherClass"> <li class="Page3 AnotherClass"> </ul> </body> As you can see, there needs to be CSS for each tab, so adding another page involves modifying both the HTML and the CSS. Is there a simple (DRY) way to check if two divs have the same class already built into jQuery? I ultimately went with this: <script> $(document).ready(function(){ var classRE = /Page\d+/i; var pageType = $('body').attr('className').match(classRE); $('li.'+pageType).addClass('Highlight'); }); </script> <style> #tabs li{bg-color: white;} #tabs li.Highlight{bg-color: orange;} </style>
