  • HOWTO: implement a jQuery version of ASP.Net MVC "Strongly Typed Partial Views"

    - by Sam Carleton
    I am working on a multi-page assessment form where the questions/responses are database driven. Currently I the basic system working with Html.BeginForm via standard ASP.Net MVC. At this point in time, the key to the whole system is the 'Strongly Typed Partial Views'. When the question/response is read from the database, the response type determines which derived model is created and added to the collection. The main view it iterates through the collection and uses the 'Strongly Typed Partial Views' system of ASP.Net MVC to determine which view to render the correct type of response (radio button, drop down, or text box). I would like to change this process from a Html.BeginForm to Ajax.BeginForm. The problem is I don't have a clue as to how to implement the dynamic creation of the question/response in the JavaScript/jQuery world. Any thoughts and/or suggestions? Here is the current code to generate the dynamic form: @using (Html.BeginForm(new { mdsId = @Model.MdsId, sectionId = @Model.SectionId })) { <div class="SectionTitle"> <span>Section @Model.SectionName - @Model.SectionDescription</span> <span style="float: right">@Html.CheckBoxFor(x => x.ShowUnansweredQuestions) Show only unaswered questions</span> </div> @Html.HiddenFor(x => x.PrevSectionId) @Html.HiddenFor(x => x.NextSectionId) for (var i = 0; i < Model.answers.Count(); i++) { @Html.EditorFor(m => m.answers[i]); } }

  • Why would certain browsers request all pages on my ASP.Net Web site twice?

    - by Deane
    Firefox is issuing duplicate requests to my ASP.Net web site. It will request a page, get the response, then immediately issue the same request again (well, almost the same -- see below). This happens on every page of this particular Web site (but not any others). IE does not do this, but Chrome also does this. I have confirmed that there is no Location header in the response, and no Javascript or meta tag in the page which would cause the page to be re-requested (if any of these were true, IE would be re-requesting pages as well). I have confirmed this behavior on multiple Firefox installs on multiple machines. Versions vary, but all are 3.x. The only difference between the two requests is the Accepts header. For the first request, it looks like this: Accept: text/html,application/xhtml+xml,application/xml;q=0.9,*/*;q=0.8 For the second request, it looks like this: Accept: */* The Content-Type response header in all cases is: Content-Type: text/html; charset=utf-8 Something else odd -- even though Firefox requests the page twice, it uses the first response and discards the second. I put a counter on a page that increments with every request. I can watch the responses come back (via the Charles proxy). Firefox will get a "1" the first time, and a "2" the second time. Yet it will display the "1," for some reason. Chrome exhibits this exact same behavior. I suspect it's a protocol-level issue, given the difference in Accepts header, but I've never seen this before.

  • Can this auto-stretcing scenario be realized undex XHTML/CSS?

    - by Vilx-
    I want two horizontal areas in my webpage. The first one is the menu. It's on the top. Unfortunately I don't know its size, and it might change in response to user actions. Below the menu is the main area which should stretch at least as far as the bottom of the window (if there is little content) or beyond (if there is a lot of content. To illustrate with ASCII art: +----------------------------------------------------+ | This area resizes vertically depending on contents | +----------------------------------------------------+ | This area stretches to the bottom of the window, | | but can be even larger if necessary. Note: this | | should be a separate area because it will contain | | children with height:100% as well. | | | +----------------------------------------------------+ Can this be done? Can it be done with Javascript? Added: To put things in perspective and avoid confusion, think of it this way: the top menu is generated by myself, but the bottom area is an IFrame which I want to fill the rest of the page. This is what it eventually comes down to anyway in my case.

  • All UITableCells rendered at once... why?

    - by Greg
    I'm extremely confused by the proper behavior of UITableView cell rendering. Here's the situation: I have a list of 250 items that are loading into a table view, each with an image. To optimize the image download, I followed along with Apple's LazyTableImages sample code... pretty much following it exactly. Really good system... for reference, here's the cell renderer within the Apple sample code: - (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath { // customize the appearance of table view cells // static NSString *CellIdentifier = @"LazyTableCell"; static NSString *PlaceholderCellIdentifier = @"PlaceholderCell"; // add a placeholder cell while waiting on table data int nodeCount = [self.entries count]; if (nodeCount == 0 && indexPath.row == 0) { UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:PlaceholderCellIdentifier]; if (cell == nil) { cell = [[[UITableViewCell alloc] initWithStyle:UITableViewCellStyleSubtitle reuseIdentifier:PlaceholderCellIdentifier] autorelease]; cell.detailTextLabel.textAlignment = UITextAlignmentCenter; cell.selectionStyle = UITableViewCellSelectionStyleNone; } cell.detailTextLabel.text = @"Loading…"; return cell; } UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier]; if (cell == nil) { cell = [[[UITableViewCell alloc] initWithStyle:UITableViewCellStyleSubtitle reuseIdentifier:CellIdentifier] autorelease]; cell.selectionStyle = UITableViewCellSelectionStyleNone; } // Leave cells empty if there's no data yet if (nodeCount > 0) { // Set up the cell... AppRecord *appRecord = [self.entries objectAtIndex:indexPath.row]; cell.textLabel.text = appRecord.appName; cell.detailTextLabel.text = appRecord.artist; // Only load cached images; defer new downloads until scrolling ends if (!appRecord.appIcon) { if (self.tableView.dragging == NO && self.tableView.decelerating == NO) { [self startIconDownload:appRecord forIndexPath:indexPath]; } // if a download is deferred or in progress, return a placeholder image cell.imageView.image = [UIImage imageNamed:@"Placeholder.png"]; } else { cell.imageView.image = appRecord.appIcon; } } return cell; } So – my implementation of Apple's LazyTableImages system has one crucial flaw: it starts all downloads for all images immediately. Now, if I remove this line: //[self startIconDownload:appRecord forIndexPath:indexPath]; Then the system behaves exactly like you would expect: new images load as their placeholders scroll into view. However, the initial view cells do not automatically load their images without that prompt in the cell renderer. So, I have a problem: with the prompt in the cell renderer, all images load at once. Without the prompt, the initial view doesn't load. Now, this works fine in Apple sample code, which got me wondering what was going on with mine. It's almost like it was building all cells up front rather than just the 8 or so that would appear within the display. So, I got looking into it, and this is indeed the case... my table is building 250 unique cells! I didn't think the UITableView worked like this, I guess I thought it only built as many items as were needed to populate the table. Is this the case, or is it correct that it would build all 250 cells up front? Also – related question: I've tried to compare my implementation against the Apple LazyTableImages sample, but have discovered that NSLog appears to be disabled within the Apple sample code (which makes direct behavior comparisons extremely difficult). Is that just a simple publish setting somewhere, or has Apple somehow locked down their samples so that you can't log output at runtime? Thanks!

  • HTML/jQuery/CSS Drop Down Menu Issue / Safari

    - by mmundiff
    I have a drop down menu that is coded in HTML, CSS, and jQuery and it works fine in Firefox and IE but not in Safari, and also not in Firefox on Mac. The drop down displays inline as opposed to list-item for the drop down in Safari.

  • JQuery checkbox state is updated differently between group click() and $.each(obj.click())

  • Change an Image while using JCrop

    - by Bathan
    Hi guys! Im working on a new feature in my site and I got stucked really bad. Im using JCrop obviously to crop an Image on my website. The new feature that I've been asked to Implement is to allow the user to change the colors of the Image being cropped. I have now 3 images , Color, GrayScale and Sepia. I can change the source of the image tag using javascript so the image gets changed without reload but I cannot do this once the JCrop has been enabled because it replaces the original Image for a new one. I thought I could disable JCrop, Replace the Image and then Re-Enable, but i couldnt do such thing. The example I found where the JCrop gets destroyed (example5 in Demo zip) uses an object : jcrop_api = $.Jcrop('#cropbox'); But Im enabling JCrop in a different manner,more like Example 3 : jQuery('#cropbox').Jcrop({ onChange: showPreview, onSelect: showPreview, aspectRatio: 1 }); How can I destroy JCrop so I can replace te Image? Is there another way to do this? Please help! I Could easily reload the page each time the user changes de color of the image but we all know that's not cool. Any comments will be apreciated. Thanks

  • $HTTP_RAW_POST_DATA and Wordpress media_handle_upload

    - by BaronVonKaneHoffen
    Hi there! So I'm making something for which users need to upload images from a canvas element (on the front end) using Wordpress's in-built Media Upload API. I've successfully uploaded images with the API from a file input in a form: <input type="file" name="async-upload" id="async-upload" size="40" /> ... <?php $new_attach_id = media_handle_upload( 'async-upload', $new_id ); ?> and I've saved images from the canvas using my own script: <script type="text/javascript"> ... var img = canvas.toDataURL("image/png"); ... ajax.send(img ); </script> ... <?php $imageData=$GLOBALS['HTTP_RAW_POST_DATA']; $filteredData=substr($imageData, strpos($imageData, ",")+1); $unencodedData=base64_decode($filteredData); $fp = fopen( 'saved_images/canv_save_test.png', 'wb' ); fwrite( $fp, $unencodedData); ... ?> Problem is, Wordpress's media_handle_upload() only accepts an index to the $_FILES array for the upload. So the question is: How can I pass the image data from HTTP_RAW_POST_DATA to it? Could I make the $_FILES['tmp-name'] point to it somehow? Could I use another script as an intermediate step somehow? Could I unleash the monkeys on the typewriter until they come up with the answer? Any help very very much appreciated! Thanks, Kane

  • AJAX Post Not Sending Data?

    - by Jascha
    I can't for the life of me figure out why this is happening. This is kind of a repost, so forgive me, but I have new data. I am running a javascript log out function called logOut() that has make a jQuery ajax call to a php script... function logOut(){ var data = new Object; data.log_out = true; $.ajax({ type: 'POST', url: 'http://www.mydomain.com/functions.php', data: data, success: function() { alert('done'); } }); } the php function it calls is here: if(isset($_POST['log_out'])){ $query = "INSERT INTO `token_manager` (`ip_address`) VALUES('logOutSuccess')"; $connection->runQuery($query); // <-- my own database class... // omitted code that clears session etc... die(); } Now, 18 hours out of the day this works, but for some reason, every once in a while, the POST data will not trigger my query. (this will last about an hour or so). I figured out the post data is not being set by adding this at the end of my script... $query = "INSERT INTO `token_manager` (`ip_address`) VALUES('POST FAIL')"; $connection->runQuery($query); So, now I know for certain my log out function is being skipped because in my database is the following data: if it were NOT being skipped, my data would show up like this: I know it is being skipped for two reasons, one the die() at the end of my first function, and two, if it were a success a "logOutSuccess" would be registered in the table. Any thoughts? One friend says it's a janky hosting company (hostgator.com). I personally like them because they are cheap and I'm a fan of cpanel. But, if that's the case??? Thanks in advance. -J

  • ASP.NET 2.0 + Firefox/Safari - UI Issues?

    - by Tejaswi Yerukalapudi
    I'm developing on a system that was originally developed five years ago. I don't have access to the complete source code of the system, but it is completely driven by XML and runs on ASP.NET 2.0. This was originally written for IE6, but since Microsoft has officially decided to dump it, we moved to IE7. Some javascript is added on the client side, but nothing that changes the UI has been done. (We had to integrate a credit card reader into the system) This code is accessed primarily on tablet PCs running windows, but I'd like to persuade my company to use the iPad. [The tablet somehow costs around 3k$. I think selling a 3000$ device to a client when you have the iPad for 500$ is ridiculous.] Now, my problem is if we open it in any other browser (Tested it on safari / firefox), the UI is completely messed up with elements completely out of place. Doesn't ASP.NET generate HTML that runs on any browser? My second question is if there are any credit card readers available in the market that integrate with the iPad. I don't really care about the software part as it's taken care by our company, I just need it to read the card details and post it to the server. Thanks, Teja.

  • trouble setting up anonymous login in ejabberd

    - by sofia
    Hi, In ejabberd.cfg I have the following {host_config, "thisislove-MacBook-2.local", [{auth_method, [internal, anonymous]}, {allow_multiple_connections, false}, {anonymous_protocol, both}]}. but when using speeqe javascript client (speeqe.com) to connect, I see it sends <body rid='1366284187' xmlns='http://jabber.org/protocol/httpbind' to='thisislove-macbook-2.local' xml:lang='en' wait='60' hold='1' window='5' content='text/xml; charset=utf-8' ver='1.6' xmpp:version='1.0' xmlns:xmpp='urn:xmpp:xbosh'/> and the server responds with <body xmlns='http://jabber.org/protocol/httpbind' sid='f89bf034b02fa6b884bb0c55be3f1f69e45e3866' wait='60' requests='2' inactivity='30' maxpause='120' polling='2' ver='1.8' from='thisislove-macbook-2.local' secure='true' authid='353072658' xmlns:xmpp='urn:xmpp:xbosh' xmlns:stream='http://etherx.jabber.org/streams' xmpp:version='1.0'><stream:features xmlns:stream='http://etherx.jabber.org/streams'><mechanisms xmlns='urn:ietf:params:xml:ns:xmpp-sasl'><mechanism>DIGEST-MD5</mechanism><mechanism>PLAIN</mechanism></mechanisms><register xmlns='http://jabber.org/features/iq-register'/></stream:features></body> Notice the mechanisms, DIGEST-MD5 & PLAIN. If I'm not mistaken it should have ANONYMOUS as a mechanism as well. So what happens is that speeqe simply terminates the connection. As such I'm thinking i must be missing something in the anonymous configuration or the muc config. In the mod_muc configg, I have {mod_muc, [ %%{host, "conference.@HOST@"}, {access, muc}, {access_create, muc}, {access_persistent, muc}, {access_admin, muc_admin}, {max_room_name, 190}, {max_room_desc, 190}, {max_users, 500} ]} So what am I missing?

  • jQuery/ajax working on IIS5.1 but not IIS6

    - by Mikejh99
    I'm running a weird issue here. I have code that makes jquery ajax calls to a web service and dynamically adds controls using jquery. Everything works fine on my dev machine running IIS 5.1, but not when deployed to IIS 6. I'm using VS2010/ASP.Net 4.0, C#, jQuery 1.4.2 and jQuery UI 1.8.1. I'm using the same browser for each. It partially works though. The code will add the controls to the page, but they aren't visible until I click them (they aren't visible though). I thought this was a css issue, but the styles are there too. The ajax calls look like this: $.ajax({ url: "/WebServices/AssetManager.asmx/Assets", type: "POST", datatype: "json", async: false, data: "{'q':'" + req.term + "', 'type':'Condition'}", contentType: "application/javascript; charset=utf-8", success: function (data) { res($.map(data.d, function (item) { return { label: item.Name, value: item.Name, id: item.Id, datatype: item.DataType } })) } }) Changing the content-type makes the autocomplete fail. I've quadruple checked and all the paths are correct, there is no document footer enabled in IIS, and I'm not using IIS compression. Any idea why the page will display and work properly in IIS 5 but only partially in IIS 6? (If it failed completely, that'd make more sense!). Is it a jQuery or CSS issue?

  • Passing jquery JSON from Codeigniter controller to view

    - by dede
    I've been struggling to make it work, but cannot pass the inserted data from the controler to the view in CI using JSON. The input value from the form is successfully inserted into the database, but cannot make it appear in the view. This is my view file ajax_view.php: <script type="text/javascript" src="<?php echo base_url(); ?>js/jquery-1.4.2.min.js"></script> $(document).ready(function(){ $("#submit").click(function(){ var inp = $('#inp').val(); $.post("ajax/ajax_input", { 'send' : inp }, function(data){ alert(data.input_text); }, "json"); }); }); </script> </head> <body> <form id="form1" method="post" action=""> <label for="inp">Text</label> <input type="text" name="inp" id="inp" /> <label for="submit"></label> <input type="submit" name="submit" id="submit" value="Submit" /> And this is the ajax_input method of the ajax.php controller: <?php // Initializing controller ..... // ............................. //ajax method function ajax_input(){ $var_1 = trim($this->input->post('send')); $array = array('input_text' => $var_1); echo json_encode($array); $this->db->insert('ajax',$array); } Trying to debug it with Firebug, it gives me that data.input_text is empty. What am I doing wrong? EDIT: I'm using XAMPP on Win, so is it posible that json configuration is the problem?

  • Semantically correct nested anchors

    - by Blackie123
    I am working on a web applicaton. And what we also create is something that could be described as inline editing. Just to portray thing I am trying to solve I use example of Facebook post. You have post like. Steve Jobs added 5 new photos Steve Jobs is link that redirects to his profile so in HTML, that would be: <div class="post-block"> <p><a href="stevejobs/" title="#">Steve Jobs</a> added 5 new photos.<p> </div> But what I want is the whole post "block" to be clickable although I want only that name to appear to be link. Normally in HTML logic would say to to this: <a href="stevejobs/" title="#"><div class="post-block"> <p><a href="stevejobs/" title="#">Steve Jobs</a> added 5 new photos.<p> </div></a> But this isn't semantically correct. Quick look to HTML 4.01 or any other standard says something like this: Links and anchors defined by the A element must not be nested; an A element must not contain any other A elements. How to create it semantically correct other than using javascript and defining div:hover state for the whole "div anchor"?

  • Why is my PHP upload script not working?

    - by Turner
    Hello all, I am doing some simple work with uploading a file. I am ignoring error checking and exceptions at this point just to get my uploads working. I have this HTML form: <form action='addResult.php' method='post' enctype='multipart/form-data' target='results_iFrame' onsubmit='startUpload();'> Entry: <input type='text' id='entry' /> Stop: <input type='text' id='stop' /> Final: <input type='text' id='final' /> Chart: <input type='file' id='chart' /> <input type='submit' value='Add' /></form> As you can see, it calls 'addResult.php' within the iFrame 'results_iFrame'. The Javascript is just for animation purposes and to tell me when things are finished. addResult.php has this code in it (along with processing the other inputs): $upload_dir = "../img/"; $chart_loc = $upload_dir.basename($_FILES['chart']['name']); move_uploaded_file($_FILES['chart']['tmp_name'], $chart_loc); print_r($_FILES); It uses the 'chart' input from the form and tries to upload it. I have the print_r() function to display some information on $_FILES, but the array is empty, thus making this fail. What could I be doing wrong?

  • Can't get jQuery to wokr with Prototype - tried everything....

    - by thinkfuture
    Ok so here is the situation. Been pulling my hair out on this one. I'm a noob at this. Only been using rails for about 6 weeks. I'm using the standard setup package, and my code leverages prototype helpers heavily. Like I said, noob ;) So I'm trying to put in some jQuery effects, like PrettyPhoto. But what happens is that when the page is first loaded, PrettyPhoto works great. However, once someone uses a Prototype helper, like a link created with link_to_remote, Prettyphoto stops working. I've tried jRails, all of the fixes proposed on the JQuery site to stop conflicts... http://docs.jquery.com/Using_jQuery_with_Other_Libraries ...even done some crazy things likes renaming all of the $ in prototype.js to $$$ to no avail. Either the prototype helpers break, or jQuery breaks. Seems nothing I do can get these to work together. Any ideas? Here is part of my application.html.erb <%= javascript_include_tag 'application' %> <%= javascript_include_tag 'tooltip' %> <%= javascript_include_tag 'jquery' %> <%= javascript_include_tag 'jquery-ui' %> <%= javascript_include_tag "jquery.prettyPhoto" %> <%= javascript_include_tag 'prototype' %> <%= javascript_include_tag 'scriptalicious' %> </head> <body> <script type="text/javascript" charset="utf-8"> jQuery(document).ready( function() { jQuery("a[rel^='prettyPhoto']").prettyPhoto(); }); </script> If I put prototype before jquery, the prototype helpers don't work If I put the noconflict clause in, neither works. Thanks in advance! Chris

  • htmlspecialchars() - How and when to use and avoid multiple use

    - by naescent
    Hi, I'm building a PHP intranet for my boss. A simple customer, order, quote system. It will be denied access from the Internet and only used by 3 people. I'm not so concerned with security as I am with validation. Javascript is disables on all machines. The problem I have is this: Employee enters valid data into a form containing any of the following :;[]"' etc. Form $_POSTS this data to a validationAndProcessing.php page, and determines whether the employee entered data or not in to the fields. If they didn't they are redirected back to the data input page and the field they missed out is highlighted in red. htmlspecialchars() is applied to all data being re-populated to the form from what they entered earlier. Form is then resubmitted to validationAndProcessing.php page, if successful data is entered into the database and employee is taken to display data page. My question is this: If an employee repeatedly enters no data in step 1, they will keep moving between step 1 and 4 each time having htmlspecialchars() applied to the data. So that:- & becomes:- &amp; becomes:- &amp;amp; becomes:- &amp;amp;amp; etc.. How can I stop htmlspecialchars() being applied multiple times to data that is already cleaned? Thanks, Adam

  • jQuery noobie can't make a checked checkbox show an alert.

    - by Kyle Sevenoaks
    I found this answer before, to fire an alert if the button is pressed but the checkbox isn't checked. Why won't this work? <input value="1" type="checkbox" name="salgsvilkar" ID="checkbox2" style="float:left;" onclick="document.getElementById('scrollwrap').style.cssText='border-color:#85c222; background-color:#E5F7C7;';" /><label for="checkbox2" class="akslabel">Salgs og leveringsvilkår er lest og akseptert</label> </span> {literal} <script type="text/javascript"> $(function() { //checkbox $("#checkbox2").click(function(){ //if this... //alert("this")... if($("#checkbox2").is(':checked')) { alert("im checked"); } }); //button $("#fullfor_btn").click(function(e){ if(!$("#checkbox2").is(':checked')) { alert("you did not check the agree to terms..."); e.preventDefault(); } }); } </script> {/literal} This on another .tpl: <label></label> <button type="submit" class="submit" name="{$method}" id="fullfor_btn" title="Fullfør bestillingen nå" value="">&nbsp;</button> What could be going wrong? The jQuery doesn't fire anything at all.

  • Asp.net Hidden field not having value in code behind, but *is* retaining value after postbacks

    - by KallDrexx
    In my ASCX, I have an asp.net hidden field defined as <asp:HiddenField ID="hdnNewAsset" runat="server" />. In the Code Behind I have the following code: protected void Page_Load(object sender, EventArgs e) { _service = new ArticleDataService(PortalId); if (!IsPostBack) { string rawId = Request[ArticleQueryParams.ArticleId]; DisplayArticleDetails(rawId); } if (hdnNewAsset.Value.Trim() != string.Empty) ProcessNewAsset(); } Now, in my frontend, I have a javascript function to react to an event and set the hidden field and trigger a postback: function assetSelected(assetGuid) { $('input[id*="hdnNewAsset"]').val(assetGuid); __doPostBack() } What's happening is that my hidden field is being set in the markup (chrome shows [ <input type=?"hidden" name=?"dnn$ctr466$Main$ctl00$hdnNewAsset" id=?"dnn_ctr466_Main_ctl00_hdnNewAsset" value=?"98d88e72-088c-40a4-9022-565a53dc33c4">? ] for $('input[id*="hdnNewAsset"]')). However, when the postback occurs, hdnNewAsset.Value is an empty string. What's even more puzzling is that at the beginning of Page_Load Request.Params["dnn$ctr466$Main$ctl00$hdnNewAsset"] shows 98d88e72-088c-40a4-9022-565a53dc33c4, and after the postback my hidden field has the same value (so the hidden field is persisting across postbacks), yet I cannot access this value via hdnNewAsset.Value. Can anyone see what I"m doing wrong?

  • Is there a max recommended size on bundling js/css files due to chunking or packet loss?

    - by George Mauer
    So we all have heard that its good to bundle your javascript. Of course it is, but it seems to me that the story is too simple. See if my logic makes sense here. Obviously fewer HTTP requests is fewer round trips and hence better. However - and I don't know much about bare http - aren't http responses sent in chunks? And if a file is larger than one of those chunks doesn't it have to be downloaded as multiple (possibly synchronous?) round trips? As opposed to this, several requests for files just under the chunking size would arrive much quicker since modern web browsers download resources like javascripts in parallel. Even if chunking is not an issue, it seems like there would be some max recommended size just due to likelyhood of packet loss alone since a bundled file must wait till it is entirely downloaded to execute, versus the more lenient native rule that scripts must execute in order. Obviously there's also matters of browser caching and code volatility to consider but can someone confirm this or explain why I'm off base? Does anyone have any numbers to put to it?

  • Need an Overview of Possibilities for multicolumn programming

    - by Sam
    Hi folks, From source1 and source2 i gather that IE9 will NOT support multi-column css3!! Since it is still the most popular browser (another thing i cannot understand), i am left but no other choice than to use Programming Power to make multi-columns work. Now, I use three divs that float to left, and which are manually filled with text. Please don't laugh i know its stupid! But I would wish to not to have to worry about the columns and just have a one piece of (un-interrupted) text which all goes into only 1 div, and then have a program smart enough to split it up into X equally wide columns. Question: before i start reinvent the wheel, what methods of programming power have you known that tackle this elegantly? Please suggest your best working multi-column layout sources so I can evaluate which option is the best (I will update the below table). Exploring all possibilities 2011 and further, to enable multi column text user experience: Language Author SourceCodeUsage WorksOnAllMajorBrowser? ================================================================================= html manual labour put text manually in separate left-floating divs "Y" // Upside: control!

  • jQuery e.stopPropagation() - how to use without breaking dropbox functionality altogether?

    - by Knut Ole
    Short story: stopPropagation() prevents a dropdown menu from closing - which is good. But it also prevents the dropbox from opening next time around - which is bad. Long story: I'm using Twitter-Bootstrap and I've put a search box inside the dropdown menu like so: <div id="search_word_menu" style="position:absolute;right:157px;top:60px;"> <ul class="nav nav-pills"> <li class="dropdown" id="menu200"> <a class="dropdown-toggle btn-inverse" data-toggle="dropdown" style="width:117px;position:relative;left:2px" href="#menu200"> <i class="icon-th-list icon-white"></i> Testing <b class="caret"></b> </a> <ul class="dropdown-menu"> <li><a href="#">Retweets</a></li> <li><a href="#">Favourites</a></li> <li class="divider"></li> <li><a href="#">A list</a></li> <li class="divider"></li> <li><a href="#">A saved search</a></li> <li><a href="#">A saved #hashtag</a></li> <li class="divider"></li> <li> <!-- HERE --> <input id="drop_search" type="text" class="search_box_in_menu" value="Search..."> </li> </ul> </li> </ul> When I click inside the searchbox, the default behaviour is obviously to close the dropdown - but that makes it rather hard to write in a search term. So I've tried with the e.stopPropagation(), which does indeed prevent the dropdown from closing. Then, when I press enter in the searchbox, I'm closing the dropdown with a .toggle() - also seems to work fine. The PROBLEM arises when I want to to it all again, because the e.stopPropagation() has now disabled the dropdown alltogether - ie. when I press the dropdown menu, it doesn't open anymore! This is because of stopPropagation(), no doubt - but how can I resolve this, so that I get the aforementioned functionality, but without breaking the rest altogether? jQuery below: $(document).ready(function() { console.log("document.ready - "); //clearing search box on click $(".search_box_in_menu").click(function(e) { e.stopPropagation(); // works for the specific task console.log(".search_box_in_menu - click."); if($(this).val() == 'Search...') { $(this).val(''); console.log(".search_box_in_menu - value removed."); }; //return false; //this is e.preventDefault() and e.stopPropagation() }); // when pressing enter key in search box $('.search_box_in_menu').keypress(function(e) { var keycode = (e.keyCode ? e.keyCode : e.which); if(keycode == '13') { console.log(".search_box_in_menu - enter-key pressed."); console.log($(this).val()); $(this).closest('.dropdown-menu').toggle(); //works } }); $('.dropdown').click(function() { console.log(".dropdown - click."); $(this).closest('.dropdown-toggle').toggle(); //does nothing }); Would greatly appreciate some help! I'm starting to suspect this might be a bootstrapped-only problem, or at least caused by their implementation - but it's beyond me atm.

  • Approaches for cross server content sharing?

    - by Anonymity
    I've currently been tasked with finding a best solution to serving up content on our new site from another one of our other sites. Several approaches suggested to me, that I've looked into include using SharePoint's Lists Web Service to grab the list through javascript - which results in XSS and is not an option. Another suggestion was to build a server side custom web service and use SharePoint Request Forms to get the information - this is something I've only very briefly looked at. It's been suggested that I try permitting the requesting site in the HTTP headers of the serving site since I have access to both. This ultimately resulted in a semi-working solution that had major security holes. (I had to include username/password in the request to appease AD Authentication). This was done by allowing Access-Control-Allow-Origin: * The most direct approach I could think of was to simply build in the webpart in our new environment to have the authors manually update this content the same as they would on the other site. Are any one of the suggestions here more valid than another? Which would be the best approach? Are there other suggestions I may be overlooking? I'm also not sure if WebCrawling or Content Scrapping really holds water here...
