  • How to load two divs into separate targets with JQuery?

    - by Bussard
    Hi all, I'm trying to achieve two things, both of which I fail to get at. On a server are a series of notes; all contain a div (id=ajxContent). Some notes also contain an additiona div (id=ajxHead). The ajxContent itself contains links (class=clicking) to call the next installment, hence the link destination in a variable. This is my code: $(document).ready(function(){ $( 'a.clicking' ).live('click', function(e){ e.preventDefault(); var theLink = $(this).attr('href'); $('#loadText').load(theLink + '#ajxContent'); $('h1').load(theLink + '#ajxHead'); }); }) Where it fails: 1) the ajxContent gets loaded into the h1 tag as well as in its intended target. 2) when I had set up the code differently, if there was no div id=ajxHead present in a note, the load would nevertheless erase the existing value in the h1 tag. Am I on a totally wrong track here, with two load statements? Input is very welcome, thanks.

  • Inserting Row in Table inside Form tag autosubmitting in firefox/chrome

    - by user1861489
    I have a form that will have dynamic elements inserted with javascript and am experiencing some strange behavior. When I click the button to add another element to the table in the form, it adds the element but seems to to a form post immediately (without intending to submit the form yet) I have created a simplified example of the page that has the same behavior. the first table element is created on page load and subsequent elements are added when clicking on the button. this form works successfully in IE. does anyone have an idea of how to prevent this behavior? here is the code sample. <!DOCTYPE html> <html> <head> <title>Test Creating Form</title> <meta http-equiv="Content-type" content="text/html;charset=UTF-8"> <style type="text/css"> td{font-family:verdana;} </style> <script type="text/javascript"> var counter = 0; function makeTitle(title){ if(counter){ title += " " + counter; } counter++; var tbl = document.getElementById('tbl'); var tr = tbl.insertRow(-1) var td1 = tr.insertCell(-1); td1.innerHTML = title; } function load1(){ makeTitle('Primary Specimen'); } </script> </head> <body onload="load1();"> <form action="formtest.htm" method="post" name="testForm" id="testForm"> <table id="tbl" border="1"></table> <button onclick="makeTitle('Alternate Specimen')" id="clone" >Add Another Specimen</button> </form> </body> </html>

    - by Yustme
    I'm trying to post a JSON array to a mvc controller. But no matter what i try, everything is 0 or null. I have this table that contains textboxes. I need from all those textboxes it's ID and value as an object. This is my java code: $(document).ready(function () { $('#submitTest').click(function (e) { var $form = $('form'); var trans = new Array(); var parameters = { TransIDs: $("#TransID").val(), ItemIDs: $("#ItemID").val(), TypeIDs: $("#TypeID").val(), }; trans.push(parameters); if ($form.valid()) { $.ajax( { url: $form.attr('action'), type: $form.attr('method'), data: JSON.stringify(parameters), dataType: "json", contentType: "application/json; charset=utf-8", success: function (result) { $('#result').text(result.redirectTo) if (result.Success == true) { return fase; } else { $('#Error').html(result.Html); } }, error: function (request) { alert(request.statusText) } }); } e.preventDefault(); return false; }); }); This is my view code: <table> <tr> <th>trans</th> <th>Item</th> <th>Type</th> </tr> @foreach (var t in Model.Types.ToList()) { { <tr> <td> <input type="hidden" value="@t.TransID" id="TransID" /> <input type="hidden" value="@t.ItemID" id="ItemID" /> <input type="hidden" value="@t.TypeID" id="TypeID" /> </td> </tr> } } </table> This is the controller im trying to receive the data to: [HttpPost] public ActionResult Update(CustomTypeModel ctm) { return RedirectToAction("Index"); } What am i doing wrong?

  • jQuery Fancy - popup window doesn't fully expand

    - by fmz
    I am using jQuery Fancybox to display a number of Flash videos on a site and I am having trouble with the window not opening fully on the first click in Firefox. It works fine in other browsers. Here is the jQuery: <script type="text/javascript"> $(document).ready(function() { $("a.videoLink").fancybox({ 'titleShow' : false, 'autoscale' : true, 'width' : '820', 'height' : '620', 'transitionIn' : 'elastic', 'transitionOut' : 'elastic' }); }); </script> Here is the html: <tr> <td class="title"><a class="videoLink" href="#video-content30">CPR Lesson 1 Movie</a></td> <td class="time">38:39</td> <td class="video" style="display:none"> <div id="video-content30"> <script type='text/javascript'> var flashvars = { file: 'http://www.stockmarketcpr.com/smsys/link/CPR-Lesson-1-Movie.flv', id: '30' }; var params = { wmode: 'opaque', bgcolor: '#CCCCCC', allowfullscreen: 'true', allowscriptaccess: 'always' }; swfobject.embedSWF('http://www.stockmarketcpr.com/_flash/player.swf', 'player30','800','600', '9.0.0','expressInstall.swf', flashvars, params); </script> <div id="player30"></div> </div> </td> </tr> I end up getting a quarter inch high, full-width window on the first click.

  • getClientRects javascript method supported on iPhone?

    - by genericdan
    Trying to find the top-most visible element in a UIWebView. I am using a JS method to do this, which works great in Safari, but never executes past the getClientRects method when executed from a UIWebView. The elements I'm interested are all of class="h". Here's the javascript which is called from [webView stringByEvaluatingJavaScriptFromString:@"findTopElement()"]; Javascript: function findTopElement() { var pars = document.getElementsByClassName("h"); alert("findingTopElement: num pars:" + pars.length); for (var i = 0; i < pars.length; i++) { var para = pars[i]; alert("checking par " + para.id); var rects = para.getClientRects(); alert("checking rects " + rects.length); for (var j = 0; j < rects.length; j++) { var r = rects[j]; if (r.top > 0 && r.bottom > 0) { alert("success: " + para.id); return para.id; } } } return -1; } Is it possible element getClientRects function is not supported in a UIWebView?

  • Why won't Internet Explorer (or Chrome) display my 'Loading...' gif but Firefox will?

    - by codeLes
    I have a page that fires several xmlHttp requests (synchronous, plain-vanilla javascript, I'd love to be using jquery thanks for mentioning that). I'm hiding/showing a div with a loading image based on starting/stopping the related javascript functions (at times I have a series of 3 xmlhttp request spawning functions nested). div = document.getElementById("loadingdiv"); if(div) { if(stillLoading) { div.style.visibility='visible'; div.style.display=''; } else { div.style.visibility='hidden'; div.style.display='none'; } } In Firefox this seems to work fine. The div displays and shows the gif for the required processing. In IE/Chrome however I get no such feedback. I am only able to prove that the div/image will even display by putting alert() methods in place with I call the above code, this stops the process and seems to give the browsers in question the window they need to render the dom change. I want IE/Chrome to work like it works in Firefox. What gives?

  • Use jQuery's dataTable plugin with a nested Ajax call

    - by mrr0ng
    I am trying to use a nested ajax call to populate a table, and once the table is built, use jQuery's dataTable plugin to pretty it up. The problem I am running into is an order of operations question. When do I call the dataTable function so that I can be assured that the table is built AFTER the values are populated? When I try the following code, the dataTable is created before the rows are built. <script type="text/javascript"> $(document).ready(function() { $.ajax({ url:"http://totalrockregistration.com/feeds/bands.php", dataType:"jsonp", success: function(jsonData){ $.each(jsonData.bands, function(i,bands){ if (bands.barID == "<?php echo $_GET["barID"]; ?>"){ var songIdFromBandJson = bands.song; var bandNameFromJson = bands.name; var bandScoreFromJson = bands.score; $.ajax({ url:"http://totalrockregistration.com/feeds/songs.php", dataType:"jsonp", success: function(songsJsonData){ $.each(songsJsonData.songs, function(i,songs){ if (songIdFromBandJson == songs.id){ var songName=(songs.name); $("#leaderBoardTable tbody").append("<tr><td>"+bandNameFromJson+"</td><td>"+bandScoreFromJson+"</td><td>"+songName+"</td></tr>"); } }); } }); } }); makeLeaderTable(); }, }); function makeLeaderTable(){ $('#leaderBoardTable').dataTable({ "aaSorting": [[ 1, "desc" ]], "iDisplayLength": 50 }); } }); </script>

  • How to prevent onclick statements from being executed?

    - by ryanli
    I want to use an event listener for preventing the onclick statement of a submit button, however, using event.preventDefault() doesn't work as intended. The code is like this: <?xml version="1.0" encoding="utf-8"?> <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Strict//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-strict.dtd"> <html xmlns="http://www.w3.org/1999/xhtml"> <head> <meta http-equiv="Content-Type" content="text/html; charset=utf-8" /> <script type="application/x-javascript"> function addListener() { document.getElementById("submit").addEventListener("click", function(ev) { alert("listener"); ev.preventDefault(); }, false); } </script> <title></title> </head> <body onload="addListener();"> <form id="form" method="post" target=""> <input type="submit" id="submit" onclick="alert('onclick')" value="test" /> </form> </body> </html> The expected behaviour is only "listener" will be alerted, but in practice (Firefox 3.7a5pre), "onclick" and "listener" are both alerted, in the given order. It seems that onclick is being executed before the listener, so event.preventDefault() doesn't work. Is there a way to prevent onclick from being executed?

  • Create a class that inherets DrawableGameComponent in XNA as a CLASS with custom functions

    - by user3675013
    using Microsoft.Xna.Framework.Graphics; using Microsoft.Xna.Framework.Media; using Microsoft.Xna.Framework; using Microsoft.Xna.Framework.Content; namespace TileEngine { class Renderer : DrawableGameComponent { public Renderer(Game game) : base(game) { } SpriteBatch spriteBatch ; protected override void LoadContent() { base.LoadContent(); } public override void Draw(GameTime gameTime) { base.Draw(gameTime); } public override void Update(GameTime gameTime) { base.Update(gameTime); } public override void Initialize() { base.Initialize(); } public RenderTarget2D new_texture(int width, int height) { Texture2D TEX = new Texture2D(GraphicsDevice, width, height); //create the texture to render to RenderTarget2D Mine = new RenderTarget2D(GraphicsDevice, width, height); GraphicsDevice.SetRenderTarget(Mine); //set the render device to the reference provided //maybe base.draw can be used with spritebatch. Idk. We'll see if the order of operation //works out. Wish I could call base.draw here. return Mine; //I'm hoping that this returns the same instance and not a copy. } public void draw_texture(int width, int height, RenderTarget2D Mine) { GraphicsDevice.SetRenderTarget(null); //Set the renderer to render to the backbuffer again Rectangle drawrect = new Rectangle(0, 0, width, height); //Set the rendering size to what we want spriteBatch.Begin(); //This uses spritebatch to draw the texture directly to the screen spriteBatch.Draw(Mine, drawrect, Color.White); //This uses the color white spriteBatch.End(); //ends the spritebatch //Call base.draw after this since it doesn't seem to recognize inside the function //maybe base.draw can be used with spritebatch. Idk. We'll see if the order of operation //works out. Wish I could call base.draw here. } } } I solved a previous issue where I wasn't allowed to access GraphicsDevice outside the main Default 'main' class Ie "Game" or "Game1" etc. Now I have a new issue. FYi no one told me that it would be possible to use GraphicsDevice References to cause it to not be null by using the drawable class. (hopefully after this last bug is solved it doesn't still return null) Anyways at present the problem is that I can't seem to get it to initialize as an instance in my main program. Ie Renderer tileClipping; and I'm unable to use it such as it is to be noted i haven't even gotten to testing these two steps below but before it compiled but when those functions of this class were called it complained that it can't render to a null device. Which meant that the device wasn't being initialized. I had no idea why. It took me hours to google this. I finally figured out the words I needed.. which were "do my rendering in XNA in a seperate class" now I haven't used the addcomponent function because I don't want it to only run these functions automatically and I want to be able to call the custom ones. In a nutshell what I want is: *access to rendering targets and graphics device OUTSIDE default class *passing of Rendertarget2D (which contain textures and textures should automatically be passed with a rendering target? ) *the device should be passed to this function as well OR the device should be passed to this function as a byproduct of passing the rendertarget (which is automatically associated with the render device it was given originally) *I'm assuming I'm dealing with abstracted pointers here so when I pass a class object or instance, I should be recieving the SAME object , I referenced, and not a copy that has only the lifespan of the function running. *the purpose for all these options: I want to initialize new 2d textures on the fly to customize tileclipping and even the X , y Offsets of where a WHOLE texture will be rendered, and the X and Y offsets of where tiles will be rendered ON that surface. This is why. And I'll be doing region based lighting effects per tile or even per 8X8 pixel spaces.. we'll see I'll also be doing sprite rotations on the whole texture then copying it again to a circular masked texture, and then doing a second copy for only solid tiles for masked rotated collisions on sprites. I'll be checking the masked pixels for my collision, and using raycasting possibly to check for collisions on those areas. The sprite will stay in the center, when this rotation happens. Here is a detailed diagram: http://i.stack.imgur.com/INf9K.gif I'll be using texture2D for steps 4-6 I suppose for steps 1 as well. Now ontop of that, the clipping size (IE the sqaure rendered) will be able to be shrunk or increased, on a per frame basis Therefore I can't use the same static size for my main texture2d and I can't use just the backbuffer Or we get the annoying flicker. Also I will have multiple instances of the renderer class so that I can freely pass textures around as if they are playing cards (in a sense) layering them ontop of eachother, cropping them how i want and such. and then using spritebatch to simply draw them at the locations I want. Hopefully this makes sense, and yes I will be planning on using alpha blending but only after all tiles have been drawn.. The masked collision is important and Yes I am avoiding using math on the tile rendering and instead resorting to image manipulation in video memory which is WHY I need this to work the way I'm intending it to work and not in the default way that XNA seems to handle graphics. Thanks to anyone willing to help. I hate the code form offered, because then I have to rely on static presence of an update function. What if I want to kill that update function or that object, but have it in memory, but just have it temporarily inactive? I'm making the assumption here the update function of one of these gamecomponents is automatic ? Anyways this is as detailed as I can make this post hopefully someone can help me solve the issue. Instead of tell me "derrr don't do it this wayyy" which is what a few people told me (but they don't understand the actual goal I have in mind) I'm trying to create basically a library where I can copy images freely no matter the size, i just have to specify the size in the function then as long as a reference to that object exists it should be kept alive? right? :/ anyways.. Anything else? I Don't know. I understand object oriented coding but I don't understand this XNA It's beggining to feel impossible to do anything custom in it without putting ALL my rendering code into the draw function of the main class tileClipping.new_texture(GraphicsDevice, width, height) tileClipping.Draw_texture(...)

  • How to make this JavaScript much faster?

    - by Ralph
    Still trying to answer this question, and I think I finally found a solution, but it runs too slow. var $div = $('<div>') .css({ 'border': '1px solid red', 'position': 'absolute', 'z-index': '65535' }) .appendTo('body'); $('body *').live('mousemove', function(e) { var topElement = null; $('body *').each(function() { if(this == $div[0]) return true; var $elem = $(this); var pos = $elem.offset(); var width = $elem.width(); var height = $elem.height(); if(e.pageX > pos.left && e.pageY > pos.top && e.pageX < (pos.left + width) && e.pageY < (pos.top + height)) { var zIndex = document.defaultView.getComputedStyle(this, null).getPropertyValue('z-index'); if(zIndex == 'auto') zIndex = $elem.parents().length; if(topElement == null || zIndex > topElement.zIndex) { topElement = { 'node': $elem, 'zIndex': zIndex }; } } }); if(topElement != null ) { var $elem = topElement.node; $div.offset($elem.offset()).width($elem.width()).height($elem.height()); } }); It basically loops through all the elements on the page and finds the top-most element beneath the cursor. Is there maybe some way I could use a quad-tree or something and segment the page so the loop runs faster?

  • Accessing HTML DOM elements from javascript using `.childNodes`

    - by Martin
    I'm wondering about the .childNodes property, I have the code below, and for some reason I get 18 children, while 6 are HTMLInputElements as expected, and the rest are undefined. What is this about? Is there an efficient way to iterate over the input elements? <html> <head> <script> window.onload = function(e){ form = document.getElementById('myForm'); alert(form.childNodes.length); for(i=0; i<form.childNodes.length; i++){ alert(form[i]); } } </script> </head> <body> <form id='myForm' action="haha" method="post"> Name: <input type="text" id="fnameAdd" name="name" /><br /> Phone1: <input type="text" id="phone1Add" name="phone1" /><br /> Phone2: <input type="text" id="phone2Add" name="phone2" /><br /> E-Mail: <input type="text" id="emailAdd" name="email" /><br /> Address: <input type="text" id="addressAdd" name="address" /><br /> <input type="submit" value="Save" /> </body> </html>

  • AppleScript: open frontmost file with another application

    - by jacobianism
    I'd like to write an AppleScript program to do the following (Automator would be fine too): I want to open the current active TextMate file (possibly there are several tabs open and other windows) with the application Transmit 2. (This will upload the file over FTP using Transmit's DockSend feature.) Here I've used a specific application (TextMate) but ideally I'd like it to work for any file currently active in any application. Ultimately I will assign a keyboard shortcut to run it. Here's what I have so far: tell application (path to frontmost application as text) set p to path of document 1 end tell tell application "Finder" open POSIX file p using "Transmit 2" end tell I've tried many variants of this and nothing works. EDIT: I have found this page: http://wiki.macromates.com/Main/Howtos and someone has made exactly the script I'm looking for: tell application "Transmit" to open POSIX file "$TM_FILEPATH" This is for Transmit [not 2] and I think for TextMate pre v2. I get the error (when using Transmit 2): Transmit 2 got an error: AppleEvent handler failed. One of the updates to v2 has broken it (not sure which one).

  • Selective replication with CouchDB

    - by FRotthowe
    I'm currently evaluating possible solutions to the follwing problem: A set of data entries must be synchonized between multiple clients, where each client may only view (or even know about the existence of) a subset of the data. Each client "owns" some of the elements, and the decision who else can read or modify those elements may only be made by the owner. To complicate this situation even more, each element (and each element revision) must have an unique identifier that is equal for all clients. While the latter sounds like a perfect task for CouchDB (and a document based data model would fit my needs perfectly), I'm not sure if the authentication/authorization subsystem of CouchDB can handle these requirements: While it should be possible to restict write access using validation functions, there doesn't seem to be a way to authorize read access. All solutions I've found for this problem propose to route all CouchDB requests through a proxy (or an application layer) that handles authorization. So, the question is: Is it possible to implement an authorization layer that filters requests to the database so that access is granted only to documents that the requesting client has read access to and still use the replication mechanism of CouchDB? Simplified, this would be some kind of "selective replication" where only some of the documents, and not the whole database is replicated. I would also be thankful for directions to some detailed information about how replication works. The CouchDB wiki and even the "Definite Guide" Book are not too specific about that.

  • Set bounds for markers generated by jQuery table loop?

    - by abemonkey
    I have some jQuery code that goes through a table of location results and puts corresponding pins on a map. I am having trouble figuring out how to set the bounds so that when it goes through the loop and generates the markers on the map that it zooms and pans to fit the markers in the view. I've tried implementing code from some similar questions on this site but nothing seems to be working. Please let me know what code I should be using and where the heck I should put it in my script: $(function() { var latlng = new google.maps.LatLng(44, 44); var settings = { zoom: 15, center: latlng, disableDefaultUI: false, mapTypeId: google.maps.MapTypeId.ROADMAP }; var map = new google.maps.Map(document.getElementById("map_canvas"), settings); $('tr').each(function(i) { var the_marker = new google.maps.Marker({ title: $(this).find('.views-field-title').text(), map: map, clickable: true, position: new google.maps.LatLng( parseFloat($(this).find('.views-field-latitude').text()), parseFloat($(this).find('.views-field-longitude').text()) ) }); var infowindow = new google.maps.InfoWindow({ content: $(this).find('.views-field-title').text() + $(this).find('.adr').text() }); new google.maps.event.addListener(the_marker, 'click', function() { infowindow.open(map, the_marker); }); }); }); `

  • Google Doclist API : bug in revision history?

    - by Jerbome
    I'm trying to manage revisions of files (not documents) stored in google docs programatically using gdata document list java library v3. I can create files and revisions using this tool : I can see them in the web UI. The thing is : the content of my revisions seems wrong. Here is my test protocol : I create a plain text file with "Hello World" in it. I upload it to gdocs without converting it. I create a revision of this file, its content changing to "Content of the second version" I create another revision, its content is now "Content of the third version" At each step, I check the content of each revision, using my app AND using the web UI. Here is what I get : First step : no problem i see one version containing the "Hello world" text Second step : no problem either, i see 2 versions, containing Hello World for the first one and Content of the second version for the second. Third step : here the problems comes. I see my 3 versions, but only the third and last seems to be correct. when i download the second version, the content is "Content of the second versio" (not a typo, it misses the 'n'). And i cannot even download the initial version, it seems to timeout. Important thing : I did not have this problem three weeks ago, my revision management worked well. I have no idea of what happens there, except it seems to be server-related, as the problem is seen either with my app or the google native webapp. Last thing : I tried using the google drive API as gdocs had been merged with drive. When i request revisions of my file, the API returns me an error saying that revisions are not supported for files, even if i can see them in the UI. I tried on converted documents, it worked. I'm looking for a workaround for this problem. Has anyone ever encountered such a problem ? Thanks in advance, Jérôme

  • How to pass a parameter in a Javascript confirm function?

    - by Miles M.
    I have something like that in my code: <?php foreach($clients as $client): ?> <tr class="tableContent"> <td onclick="location.href='<?php echo site_url('clients/edit/'.$client->id ) ?>'"><?php echo $client->id ?></td> <td><a class='Right btn btn-danger' onClick="ConfirmMessage('client', <?php $client->id ?>,'clients')"> <i class="icon-remove-sign icon-white"></i> </a></td> </tr> <?php endforeach ?> that's actually the view. So when the user click on the delete button (thr one with the btn-danger class) I'd like him to confirm his choice with a javascript confirmation box message. You can find that script in the header <script> function ConfirmMessage(type, id, types) { if (confirm("Are you sure you want to delete this ",type," ?")) { // Clic sur OK document.location.href='<?php echo site_url(); ?>',types,'/delete/',id; } } </script> So here is my question: I would like the $type to be replaced by a paramenter (like client, article, post .. ) that I'll pass to the function. And i would like to get the $client-id parameter as well. I'm bad in javascript and as you already have guess, It is obviously not working at all.

The resize part is very important because the images can be very large and I want to make the thumbnails small of size. Here is my code: loadingGif(drop); for (var i=0;i<files.length;i++) { var file = files[i]; var reader = new FileReader(); reader.onload = function(e) { var src = e.target.result; var img = document.createElement('img'); img.src = src; var scale = 100/img.height; img.height = 100; img.width = scale*img.width; output.push('<div id="imagecontainer"><div id="image">'+img+'</div><div id="delimage"><img src="img/del.jpg"" /></div></div>'); if(output.length == files.length) { drop.removeChild(drop.lastChild); drop.innerHTML += output.join(''); output.length = 0; } } reader.readAsDataURL(file); } As you can probably tell I insert a loading gif image in my dropzone until all files are loaded (output.length == files.length). When a file is loaded I add html to an array which I will print if the load is complete. The problem is I can't seem to add the img object (I need this object to resize the image) to the html string, which seems obvious as the img is an object... So my question to you guys is: how do I do this? :)

  • How to get the value of an XML element using Linq even when empty.

    - by Yeodave
    Please excuse my stupidity, I tend to find the traversing XML overly complicated. I am using ASP.NET in VB. I have an XML document which contains all the details of staff in my company... <staff> <staffName>Test Staff</staffName> <staffTitle>Slave</staffTitle> <staffDepartmentName>Finance</staffDepartmentName> <staffOffice>London</staffOffice> <staffEmail>[email protected]</staffEmail> <staffPhone>0207 123 456</staffPhone> <staffNotes>Working hours Mon to Thurs 9.15 - 5.15</staffNotes> <staffBio></staffBio> </staff> As you can see, some nodes do not always contain data for ever member of staff; only Directors have biographies. I access the values like this... For Each staff In ( _ From matches In myXMLFile.Descendants("staff").Descendants("staffName") _ Where matches.Nodes(0).ToString.ToLower.Contains(LCase(search)) _ Order By matches.Value _ Select matches) staffName = staff.Descendants("staffName").Nodes(0).ToString) staffTitle = staff.Descendants("staffTitle").Nodes(0).ToString) staffOffice = staff.Descendants("staffOffice").Nodes(0).ToString) staffEmail = staff.Descendants("staffEmail").Nodes(0).ToString) staffPhone = staff.Descendants("staffPhone").Nodes(0).ToString) staffNotes = staff.Descendants("staffNotes").Nodes(0).ToString) staffBio = staff.Descendants("staffBio").Nodes(0).ToString) ' Do something with that data... Next Once it gets to staffBio I get an error saying "Object reference not set to an instance of an object." obviously because that node does not exist. My question is how can I assign the value to a variable even when it is empty without having to do a conditional check before each assignment?

  • html/js: Refresh 'Select' options

    - by framara
    Hi, There's a class 'Car' with brand and model as properties. I have a list of items of this class List<Car> myCars. I need to represent in a JSP website 2 ComboBox, one for brand and another for model, that when you select the brand, in the model list only appear the ones from that brand. I don't know how to do this in a dynamic way. Any suggestion where to start? Thanks Update Ok, what I do now is send in the request a list with all the brand names, and a list of the items. The JSP code is like: <select name="manufacturer" id="id_manufacturer" onchange="return getManufacturer();"> <option value=""></option> <c:forEach items="${manufacturers}" var="man"> <option value="${man}" >${man}</option> </c:forEach> </select> <select name="model" id="id_model"> <c:forEach items="${mycars}" var="car"> <c:if test="${car.manufacturer eq man_selected}"> <option value="${car.id}">${car.model}</option> </c:if> </c:forEach> </select> <script> function getManufacturer() { man_selected = document.getElementById('id_manufacturer').value; } </script> How do I do to refresh the 'model' select options according to the selected 'man_selected' ?

  • Issues with simple jQuery image gallery with Colorbox plugin

    - by Chris
    I'm putting together an image gallery for an ecommerce site and wanting to use colorbox to launch larger images. My problem is that image launched in colorbox stays as the first one launched and should reflect the image shown as img#bigpic - the link to the image does appear to be updating correctly. Here's the jQuery I have: $(document).ready(function(){ $("#largeimage").colorbox(); imageSwapper(".thumbnails a"); function imageSwapper(link) { $(link).click(function(){ $("#bigpic").attr("src", this.href); $("#largeimage").attr("href", this.rel); return false; }); }; $("#largeimage").bind('mouseenter mouseleave', function(event) { $("#largeimage span").toggleClass('showspan'); }); }); ...and the HTML <a href="_images/products/large/bpn0001_1.jpg" id="largeimage"><span></span><img src="_images/products/bpn0001_1.jpg" id="bigpic" /></a> <div class="thumbnails"> <ul> <li><a href="_images/products/bpn0001_1.jpg" rel="_images/products/large/bpn0001_1.jpg"><img src="_images/products/mini/bpn0001_1.jpg" /></a></li> <li><a href="_images/products/bpn0001_2.jpg" rel="_images/products/large/bpn0001_2.jpg"><img src="_images/products/mini/bpn0001_2.jpg" /></a></li> <li><a href="_images/products/bpn0001_3.jpg" rel="_images/products/large/bpn0001_3.jpg"><img src="_images/products/mini/bpn0001_3.jpg" /></a></li> </ul> </div> Any help would be much appreciated!

  • f:ajax not working on tomcat7/eclipse

    - by mntgoat
    I have this very simple code which works fine until I add a f:ajax tag. Code that works: <h:commandButton disabled="#{!feature.available}" class="featureButton" value="#{feature.selected ? 'selected': feature.available? 'available':'unavailable'} " style="vertical-align: top;" action="#{Bean.toggleFeature(feature)}"> </h:commandButton> Code that doesn't work: <h:commandButton disabled="#{!feature.available}" class="featureButton" value="#{feature.selected ? 'selected': feature.available? 'available':'unavailable'} " style="vertical-align: top;" action="#{Bean.toggleFeature(feature)}"> <f:ajax event="click" /> </h:commandButton> As far as I can tell the jsf.js file is loaded fine, this is automatically added by the facelet servlet to the head of my rendered document <script type="text/javascript" src="/www/javax.faces.resource/jsf.js.xhtml?ln=javax.faces"></script> and I was even able to do a jsf.ajax.request directly from javascript and got the page to rerender something. I am using mojarra 2.1.13, tomcat 7, eclipse juno, java 7. Any thoughts on what I might be doing wrong or how I might be able to troubleshoot this issue? debugging it in javascript didn't help at all. Thanks.
