  • element height after content change

    - by Neph
    I have a snippet of code that alters the contents of a DIV to match the contents of a textarea and then applies the height change in the DIV to the textarea element. function growTextArea(parameter) { $('div').find("[data-fieldid='1_description']").text($(parameter).val()); // No Works height = $('.hiddenDiv').find("[data-fieldid='1_description']").outerHeight(); alert(height); // Works heightDiv = $('.hiddenDiv').outerHeight(); alert(heightDiv); $(parameter).css('height', $('div').find("[data-fieldid='1_description']").outerHeight()); } The DIV contents change properly, so the search function is working properly, however the search function always returns the original height of the DIV. The function is called by onKeyUp in the textarea. If the .find is swapped out for a .hiddenDiv the height change is reflected properly.

  • Why is my long polling code for a notification system not updating in real time? PHP MYSQL

    - by tjones
    I am making a notification system similar to the red notification on facebook. It should update the number of messages sent to a user in real time. When the message MYSQL table is updated, it should instantly notify the user, but it does not. There does not seem to be an error inserting into MYSQL because on page refresh the notifications update just fine. I am essentially using code from this video tutorial: http://www.screenr.com/SNH (which updates in realtime if a data.txt file is changed, but it is not written for MYSQL like I am trying to do) Is there something wrong with the below code: **Javascript** <script type="text/javascript"> $(document).ready(function(){ var timestamp = null; function waitForMsg(){ $.ajax({ type: "GET", url: "getData.php", data: "userid=" + userid, async: true, cache: false, success: function(data){ var json = eval('(' + data + ')'); if (json['msg'] != "") { $('.notification').fadeIn().html(json['msg']); } setTimeout('waitForMsg()',30000); }, error: function(XMLHttpRequest, textStatus, errorThrown){ setTimeout('waitForMsg()',30000); } }); } waitForMsg(); </script> <body> <div class="notification"></div> **PHP*** <?php if ($_SERVER['REQUEST_METHOD'] == 'GET' ) { $userid = $_GET['userid']; include("config.php"); $sql="SELECT MAX(time) FROM notification WHERE userid='$userid'"; $result = mysql_query($sql); $row = mysql_fetch_assoc($result); $currentmodif = $row['MAX(time)']; $s="SELECT MAX(lasttimeread) FROM notificationsRead WHERE submittedby='$userid'"; $r = mysql_query($s); $rows = mysql_fetch_assoc($r); $lasttimeread = $rows['MAX(lasttimeread)']; while ($currentmodif <= $lasttimeread) { usleep(10000); clearstatcache(); $currentmodif = $row['MAX(time)']; } $response = array(); $response['msg'] = You have new messages; echo json_encode($response); } ?>

  • Overlapping elements stop overlapping in IE7 on class change

    - by Gazzer
    On this page http://zenchan.com/program/ When I rollover the right box 2nd from the top suddenly the overlapping (negative margin disappears). What's happening is that a 'hover' class is being added to shift the background sprite. The two yellow boxes are debugging: if the hover class is put their in advance there is no problem. So fundamentally the CSS is not a problem for IE7 but adding the class is. Any ideas what's causing this. I've tried adding haslayout to various elements but to little effect.

  • Unexpected token from webservice

    - by Kenneth B
    I got this little snippet where I call a Battlefield 3 stat server. If you visit this URL, which I'm calling, we'll be getting no errors: http://api.bf3stats.com/pc/server/?output=json&id=534f7035-cef8-48aa-b233-8d44a0956e68 But when I try to get the stats via Ajax call, I get: Uncaught SyntaxError: Unexpected token : ... In my console I can see that the response is coming in, as when I visit the url, but I can't get the data with the ajax call... Is there something wrong with my code??? $.ajax({ type: "GET", url: "http://api.bf3stats.com/pc/server/?output=json&id=534f7035-cef8-48aa-b233-8d44a0956e68", dataType: "jsonp", success: function(response) { console.log(response); } }); Thank you in advance...

  • Prevent hash navigation url

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

  • New Site : Showing first time visitors what the site offers

    - by PlanetUnknown
    The site I'm working on, is almost completed. I have a Demo page created as well, where people can try out the product. However for first time visitors to understand what service the site actually provides I'm brainstorming with the following ideas. Since a lot of folks have been through this a number of time, would like to get some advice on what they use and what generally works. Here is what I came up with - 1.) Plain Slideshow, showing various features. (Using jQquery, hence figuring out a simple BUT professional looking plugin).Simplest to implement. 2.) Flash - Will have to hire someone. 3.) JellyVision ? - I'm not sure if this is free though. But something free like this would be great !

  • add/delete image ID to/from textbox when image clicked

    - by Huseyin
    I am working on a simple news module. There is a form where user adds multiple image IDs to one textbox then submits it. To improve the usability, I listed all the images they can add (ID numbers displayed next to it) on one side. However, this still is little bit confusing. I want image IDs added/deleted to the textbox when user clicks on the images. Spare me codes, methods, ideas, examples... I will take anything.

  • Search and highlight in html with multiple keywords as a single string

    - by Qiusheng
    In JavaScript, by given a html string with tags like: This string has different fonts. <b>This</b> <i>string</i> <span style="background-color: rgb(212, 239, 181);">has</span> <b>different</b> <i>fonts</i>. When user searches for a search term with multiple words like "different fonts". How can I add highlighting to make the html string look like: <b>This</b> <i>string</i> <span style="background-color: rgb(212, 239, 181);">has</span> <span class="highlight"> <b>different</b> <i>fonts</i> </span>. Please note that the search term is treated as a single string as if the words are in a quote, so I cannot search and highlight each word individually.

  • JSON from $.each()

    - by Matthew
    I'm trying to get a list of the values of all checked checkboxes that looks like this: foo = { 'colors': ['blue', 'red', 'green'], 'flavors': ['vanilla', 'chocolate'] }; This is the approach I'm taking so far, but JS is saying that 'colors' doesn't exist when I try to push a new value to it. I'm assuming this is a scope issue but I don't know how to fix it. var foo = {}; foo.colors = []; $(".colors:checked").each(function(){ foo.colors.push($(this).val()); });

  • Refactor: Javascript block

    - by Shpigford
    Need some help refactoring this code: $("span[rel=color_content]").ColorPicker({ onChange: function (hsb, hex, rg) { $("span[rel=color_content]").css('background-color', '#' + hex); } }); $("span[rel=color_link]").ColorPicker({ onChange: function (hsb, hex, rg) { $("span[rel=color_link]").css('background-color', '#' + hex); } }); $("span[rel=color_selected]").ColorPicker({ onChange: function (hsb, hex, rg) { $("span[rel=color_selected]").css('background-color', '#' + hex); } }); $("span[rel=color_page]").ColorPicker({ onChange: function (hsb, hex, rg) { $("span[rel=color_page]").css('background-color', '#' + hex); } }); $("span[rel=color_player]").ColorPicker({ onChange: function (hsb, hex, rg) { $("span[rel=color_player]").css('background-color', '#' + hex); } }); The only thing changing between each is the contents of the rel attribute.

  • Reset after using a link with parameters

    - by CarolinaJay65
    I am using the window.location.search parameters (www.mysite.com?page=1) to direct the user to a specific page within the site. However, since those parameters are still in window.location (the browser) reset button continues to re-direct to the same page. I would like the reset button to re-direct to www.mysite.com How do I clear the .search parameters so the (browser) reset button re-directs where I want? Is it done after the page is loaded? or after the (browser) reset button has been clicked?

  • Slick PHP based image manager for managing user profile images

    - by franko75
    Hi, I'm just throwing this out there as I'm plodding my way through creating a Member Photo album on a site i'm working on, where they can login and upload their photos to a personal gallery. I want this to be nice and lightweight, but still slick and "modern" with a modal based interface for the user. I'm surprised though that there is seemingly nothing open source out there which fits the bill - I've done a few searches on Google to no avail and can't seem to find anything. Lots of bloated photo galleries out there but nothing looks like it has been developed using more recent technologies. Is anyone aware of anything which might suit what I'm looking for? I'm fully prepared to try and code it myself but I'd be delighted if I didn't have to! Pure laziness you might say, but there's no point reinventing the wheel.

  • save jQuerry changes to css file on server

    - by KrisRogo
    I'm developing a system that allows for changing some of the css parameters without accessing the code. To achieve that I have jQuerry objects like sliders and draggers which influence how the site looks user side, eg. $("#MainContent").css("width", "55%");. Now I need a way to append those changes to a .css file on the server. Let me clarify that this is sort of a CMS system, and only administrator of the system would have this option, not the visitors of user-end site. I realise that .css is one for all users. Ideal solution would connect to the server every time user makes a change, and replace only one line of css code. But I have no idea how to do it efficiently or if it at all possible.

  • Which browser versions do YouTube and Google Apps support?

    - by Alex
    Hi. We're building a site and wish to build for the same set of browsers Google Apps/Docs and YouTube support. Though not recommended, they seem to be detecting specific browsers/versions vs. features/functionality. What's the best way to support a minimum set of browsers while displaying a message to the users of older browsers to upgrade? What's the minimum set of browsers that the major sites are supporting? Thanks.
