  • Background-image toggle using jquery

    - by Jon
    Hi all, bit of a jquery rookie here trying to get something to work. Basically I have a div with a class "nav" and inside that div is a nav list. I want to change the background-image of "nav" when hovering over an item in the navlist, so I made this unsuccesful effort: enter code here $(function(){ $("li#hover-first").mouseover(function(){ $("div.nav").removeClass("nav").addClass("navbg"); .mouseout(function(){$("div.nav").removeClass("navbg").addClass("nav"); }); So the idea is, once the first li item is hovered over, the div with classname "nav" has it's class removed and has "navbg" added (which has the alternate background image). Obviously this isn't working, so any help would be greatly appreciated...thanks.

  • How do you make an image opened in colorbox scrollable

    - by nicholas.alipaz
    I would like my images that I open in colorbox to be displayed fullsize with no resizing applied to them and then apply scrollbars to allow for viewing the larger images. Some of my images are quite tall and things get pixelated when resized down. Currently colorbox just resizes my images down to the size of the available height/width. Is there a way to make all images display fullsize with overflow scrollable in colorbox? I am linking directly to an image: <a href="/myimage.png" title="My Image" class="colorbox imagefield imagefield-imagelink imagefield-field_portfolio_screenshot initColorbox-processed cboxElement" rel="gallery-12"> <img src="/thumb/myimage.png" alt="image" title="My Image" class="imagecache imagecache-portfolio_screenshot_thumb" height="50" width="50"> </a>

  • jQuery - iGoogle style interface

    - by samhamilton
    Hi all, I'm currently working on developing a customizable website layout using jQuery, so I can drag, drop, add and remove blocks of content... much like the iGoogle interface. I have my blocks dragging and dropping working with 3 columns of content My question is to do with adding and removing blocks If I use hide(), I can simply hide and show the blocks. If I use remove, I would have to append the list of blocks to load in a new block into a column. I'm not sure which is the best approach to take. I'd be grateful for any advice on best practise, i.e. to hide() or remove() and any other advice on building this kind of interface. Thank, Sam.

  • Saving elements to database with $.ajax()

    - by Justin Meltzer
    I'm trying to save dynamically created elements in my application.js file to the database. Would the code look something like this?: $.ajax({ type: "POST", data: { title: 'oembed.title', thumbnail_url: 'oembed.thumbnail_url'} }); Is there anything I'm missing? Assume that oembed.title and oembed.thubnail_url hold the values I want to save, and that title and thumbnail are the database columns.

  • jquery form validation

    - by kalpaitch
    I am using jquery for a quick and easy form validation My forms use the input's default value as a label and I have a little onfocus and onblur javascript function to show and hide this when the user starts to type: <input name='fnameREG' type='text' id='fnameREG' value='first name' size='70' onfocus='clearInput(this)' onblur='clearInput(this)' /> <input name='lnameREG' type='text' id='lnameREG' value='last name' size='70' onfocus='clearInput(this)' onblur='clearInput(this)' /> My issue with the validation is that when the submit button is clicked the pluggin thinks that all the fields are set because they have a default value. I looked but I couldn't find a supplied method to get round this. Thanks!

  • jQuery if checkbox is checked to toggle classes

    - by Lynx
    I am needed to change my jQuery code up. Instead of the label toggling the class and showing the icon I need it to where if the checkbox is checked to show to toggle those classes. I have tried prop and is but I couldn't get them to work properly. The reason for the change is I want to preload data into the form and if it's going to be checked those toggles need to reflect that change. http://jsfiddle.net/70fbLooL/2/ EDIT Seems to be confusion as to exactly what I am trying to do. The fiddle I provided works perfectly fine. The problem is if I want to call the form from server-side and pre-populate the form the checkbox toggles will not show that they are checked because it's based on the clicked function. I need it to be based on if the checkbox equal true or checked. That way if the value equals true from the server-side call it will toggle those classes and look like it's checked.

  • How do you detect when the Flowplayer has started playing the video?

    - by Alex
    Hi. I'm using the Flowplayer Flash video player to play MP4 videos inside an AnythingSlider. I need to detect when the user has clicked the start button on the video so to stop the slideshow and allow the user to view the video. I've tried using this code just to get an alert box but it doesn't do anything (the code is at the end of the page, before the closing </body> tag): <script type="text/javascript"> $f("player","global/js/flowplayer/flowplayer-3.1.5.swf",{ onStart: function(clip) { alert('player started'); } }); </script> The Flowplayer is implemented as part of the html5media library, which automatically detects whether the browser can handle the <video> tag; if not, it replaces the anchor tag below with the Flowplayer: <video id="vid" width="372" height="209" poster="global/vid/bbq-poster.jpg" controls preload> <source id="videoSource" src="global/vid/BBQ_Festival.mp4" type='video/mp4; codecs="avc1.42E01E, mp4a.40.2"' onerror="fallback(this.parentNode)" ></source> <a href="global/vid/BBQ_Festival.mp4" style="display:block;width:372px;height:209px; padding-left:5px; " id="player"> </a> </video> So the $f() function call is in a JavaScript block at the end of the page, to give the player a chance to load correctly. What am I doing wrong? Thanks.

  • Returned JSON is seemingly mixed up when using jQuery Ajax

    - by Niall Paterson
    I've a php script that has the following line: echo json_encode(array('success'=>'true','userid'=>$userid, 'data' => $array)); It returns the following: { "success": "true", "userid": "1", "data": [ { "id": "1", "name": "Trigger", "image": "", "subtitle": "", "description": "", "range1": null, "range2": null, "range3": null }, { "id": "2", "name": "DWS", "image": "", "subtitle": "", "description": "", "range1": null, "range2": null, "range3": null } ] } But when I call a jQuery ajax as below: $.ajax({ type: 'POST', url: 'url', crossDomain: true, data: {name: name}, success: function(success, userid, data) { if (success = true) { document.write(userid); document.write(success); } } }); The userid is 'success'. The actual success one works, its true. Is this malformed data being returned? Or is it simply my code? Thanks in advance, Niall

  • Is this a valid jquery getJSON call?

    I am using jquery getJSON with asp.net mvc controller... I cant able to get it work.... public JsonResult GetMaterials(int currentPage,int pageSize) { var materials = consRepository.FindAllMaterials().AsQueryable(); var results = new PagedList<MaterialsObj>(materials, currentPage-1, pageSize); return Json(results); } and i am calling this with, $.getJSON('Materials/GetMaterials', "{'currentPage':1,'pageSize':5}", function(data) { }); This call doesn't seem to work.... when inspected through firebug i found this, The parameters dictionary contains a null entry for parameter 'currentPage' of non-nullable type 'System.Int32' for method 'System.Web.Mvc.JsonResult GetMaterials(Int32, Int32)' in 'CrMVC.Controllers.MaterialsController'. To make a parameter optional its type should be either a reference type or a Nullable type.<br> Parameter name: parameters

  • JQuery: Get length of JSON reply?

    - by Rosarch
    In a JQuery getJSON call, how can I tell the length of the JSON that's returned? function refreshRoomList() { $.getJSON('API/list_rooms', function (rooms) { if (rooms.length > 0) { $("#existing-room-list").empty(); $("#join-existing-room").text("Join existing room:"); // this shouldn't be here $.each(rooms, function (index, roomName) { var newChild = sprintf('<li><a href="room?key=%s">%s</a></li>', index, roomName); $("#existing-room-list").append(newChild); }); } else { $("#join-existing-room").text("No rooms found."); } }); } For some reason this doesn't work, but if I replace rooms.length > 0 with true, the full list of rooms is printed out.

  • Jquery autocomplete for input form, using Textpattern category list as a source

    - by John Stephens
    I'm using the Textpattern CMS to build a discussion site-- I have a firm grasp of XHTML and CSS, as well as Textpattern's template language, but PHP and Javascript are a bit beyond my cunning. On the input form to begin a new topic, users need to select a category from a list of over 5,000 options. Using the HTML select-type input element is very unwieldy, but it works. I would like to use some kind of Javascript magic to display a text-type input element that will read user input and display matches or autocomplete from the available categories, passing the required option's value into the appropriate database field. I've seen several autocomplete plugins for jquery, but the instructions presuppose that you understand how Javascript works. As I mentioned above, it's easy for me to generate the category list as a select-type input element, and I can hide that element using CSS. Is it possible to control select-list input using an autocomplete mechanism in a text-type input element? How would I do that?

    Given the following plugin how would you set defaults for all the instances? I would like it to work the same as $.datepicker.setDefaults(). (function ($) { $.fn.borderSwitcher = function (options) { defaults = { borderColor: 'Black', borderWidth: '1px', borderStyle: 'solid' }; return this.each(function () { var settings = $.extend(defaults, options); $(this).focus(function () { //find a better way to set border properties var props = settings.borderStyle + ' ' + settings.borderWidth + ' ' + settings.borderColor; $(this).css('border', props); }); $(this).blur(function () { $(this).css('border', ''); }); }); }; })(jQuery);

  • Jquery Ignore Event

    - by HealthWarning
    I'll just go straight to the point. Let's say we have this markup: <span href="">Text <a href="">Link</a></span> We have events bound to both elements. How do I make it such that when I click on the anchor tag, the event on the parent will not be triggered? I've tried using the Jquery method stopPropagation() but still no luck. Any thoughts? Thanks.

  • jQuery not refreshing tabs content in IE

    - by iddimu
    Hi all! I have a page that is using jQuery tabs. Within one of my tabs I have a div that contains a form (initially hidden) that I want to use to add content to the tab. What I have works perfectly in Chrome, Firefox, and Safari. But, in IE 7 the tab will not refresh. The post works and the data gets added to the database, but it simply will not show the new content after submitting it. I don't think it matters - but, just for information I am using the Codeigniter PHP framework as well. Here is my javascript: <script type="text/javascript"> $(document).ready(function(){ // initialize the addChild form as hidden until user requests it open $('#addChild').hide(); // open the form $('#openDialog').click( function(){ $('#addChild').slideToggle(); return false; }); // close the form $('#closeDialog').click( function(){ $('#addChild').slideToggle(); return false; }); // submit the form $('#frmAddChild').submit( function(){ $('#addChild').slideToggle(); $.ajax({ url: '/children/add', type: 'POST', data: $('#frmAddChild').serialize() //cache: false }); //reload the children tab $('#tabs').tabs('load',3); return false; }); }); </script> And, here is my PHP/HTML: <?php // initialize the elements of the form $frmAddChild = array( 'name' => 'frmAddChild', 'id' => 'frmAddChild', 'method' => 'post' ); $child_name = array( 'name' => 'child_name', 'id' => 'child_name', ); $child_dob = array( 'name' => 'child_dob', 'id' => 'child_dob' ); $btnOpenDialog = array( 'name' => 'openDialog', 'id' => 'openDialog', 'value' => 'true', 'content' => 'Add Child' ); $btnCloseDialog = array( 'name' => 'closeDialog', 'id' => 'closeDialog', 'value' => 'true', 'content' => 'Cancel' ); // button that shows the drop down to add echo form_button($btnOpenDialog); ?> <div id="addChild" title="Add Child"> <?php echo form_open('children/add/',$frmAddChild); ?> <table> <tr> <td> <?php echo form_label('Child\'s Name', 'child_name'); ?>: </td> <td> <?php echo form_input($child_name); ?> </td> </tr> <tr> <td> <?php echo form_label('Date of Birth','child_dob'); ?>: </td> <td> <?php echo form_input($child_dob); ?> </td> </tr> <tr> <td colspan="2" align="right"> <?php echo form_submit('submit', 'Add'); ?> <?php echo form_button($btnCloseDialog); ?> </td> </tr> </table> <?php echo form_close(); ?> </div> Does anyone have any ideas how I can get this working correctly in IE? Also, if anyone has any comments about how I have things structured, please let me know. I'm new to Codeigniter and I am by no means a javascript or jQuery expert. Thanks for your help!

  • jQuery class adding and removing with click and mouseleave

    - by danixd
    I just want to control a div by toggling a class on click, as well as removing it when the mouse leaves the div. I had it working with mouseout, but when I entered over a child element, the mouseOut triggered, so I know I need to use mouseleave. I am just unsure how incorporate telling jQuery the mouse has entered. Yes I am new to this! Here is my code: $(function(){ $('.main').click(function() { $(this).toggleClass('activated'); }); }); $(function(){ $('.main').mouseleave(function() { $(this).removeClass('activated'); }); });

  • Best way to add an extra (nested) form in the middle of a tabbed form

    - by Scharrels
    I've got a web application, consisting mainly of a big form with information. The form is split into multiple tabs, to make it more readable for the user: <form> <div id="tabs"> <ul> <li><a href="#tab1">Tab1</a></li> <li><a href="#tab2">Tab2</a></li> </ul> <div id="tab1">A big table with a lot of input rows</div> <div id="tab2">A big table with a lot of input rows</div> </div> </form> The form is dynamically extended (extra rows are added to the tables). Every 10 seconds the form is serialized and synchronized with the server. I now want to add an interactive form on one of the tabs: when a user enters a name in a field, this information is sent to the server and an id associated with that name is returned. This id is used as an identifier for some dynamically added form fields. A quick sketchup of such a page would look like this: <form action="bigform.php"> <div id="tabs"> <ul> <li><a href="#tab1">Tab1</a></li> <li><a href="#tab2">Tab2</a></li> </ul> <div id="tab1">A big table with a lot of input rows</div> <div id="tab2"> <div class="associatedinfo"> <p>Information for Joe</p> <ul> <li><input name="associated[26][]" /></li> <li><input name="associated[26][]" /></li> </ul> </div> <div class="associatedinfo"> <p>Information for Jill</p> <ul> <li><input name="associated[12][]" /></li> <li><input name="associated[12][]" /></li> </ul> </div> <div id="newperson"> <form action="newform.php"> <p>Add another person:</p> <input name="extra" /><input type="submit" value="Add" /> </form> </div> </div> </div> </form> The above will not work: nested forms are not allowed in HTML. However, I really need to display the form on that tab: it's part of the functionality of that page. I also want the behaviour of a separate form: when the user hits return in the form field, the "Add" submit button is pressed and a submit action is triggered on the partial form. What is the best way to solve this problem?

  • Jquery Delay Function Calls

    - by fizgig07
    I'm trying to find a way to delay all code that takes place after I make a service call. The reason for this delay is that my service returns code necesarry for the following functions and the result I pass is to these following functions is undefined. I have tried attaching the setTimeout() to the function that is called directly after the service call, but then it just skips the function I set the timeout on and jumps to the next function...My web method that I am calling is not that big and is not doing anything that is too intensive public bool GetSpreadsheetStatusForAdmin(string cacId) { SpreadSheetStatus result = new SpreadSheetStatus(); List<Data.Spreadsheet> spreadsheets = SpreadsheetManager.GetUserSpreadsheets(GetCurrent.Identity); if (spreadsheets.Count != 0) { foreach (Data.Spreadsheet spreadsheet in spreadsheets) { if (spreadsheet.Status == SpreadsheetStatus.Pending) { return true; } } } return false; } I had found the delay() and thought that might work, but I don't have jquery 1.4 and can't use it as of yet. is there anything that can help..?

  • jQueryUI Modal confirmation dialog on form submission

    - by DavidYell
    I am trying to get a modal confirmation dialog working when a user submits a form. My approach, I thought logically, would be to catch the form submission. My code is as follows, $('#multi-dialog-confirm').dialog({ autoOpen: false, height: 200, modal: true, resizable: false, buttons: { 'Confirm': function(){ //$(this).dialog('close'); return true; }, 'Cancel': function(){ $(this).dialog('close'); return false; } } }); $('#completeform').submit(function(e){ e.preventDefault(); var n = $('#completeform input:checked').length; if(n == 0){ alert("Please check the item and mark as complete"); return false; }else{ var q = $('#completeform #qty').html(); if(q > 1){ $('#multi-dialog-confirm').dialog('open'); } } //return false; }); So I'm setting up my dialog first. This is because I'm pretty certain that the scope of the dialog needs to be at the same level as the function which calls it. However, the issue is that when you click 'Confirm' nothing happens. The submit action does not continue. I've tried $('#completeform').submit(); also, which doesn't seem to work. I have tried removing the .preventDefault() to ensure that the form submission isn't completely cancelled, but it doesn't seem to make a difference between that and returning false. Not checking the box, show and alert fine. Might change to dialog at some point ;), clicking 'Cancel' closes the dialog and remains on the page, but the elusive 'Confirm' buttons seems to not continue with the form submission event. If anyone can help, I'd happily share my lunch with you! ;)
