  • Is there a workaround to Safari's/Opera's bug that you can't tab through hyperlinks?

    - by scunliffe
    In IE, Firefox, Chrome and most Windows-based interfaces that I've used, the Tab key can be used to navigate from one form field or hyperlink to the next (e.g. "actionable" items) (note: I have not tested on other Operating Systems) However Safari and Opera skip all hyperlinks in a web page when tabbing. IMHO its a usability bug but I digress. Is there a workaround/hack to make Safari and/or Opera navigate through these links? I've noticed that Opera will accept the tabindex attribute if set e.g. tabindex="0" thus maintaining the links "index" within the flow of the DOM on the page... but Safari does not want to accept this. For those interested, this bit of jQuery will make all the hyperlinks clickable. //Make links 'tab-able' in Opera $(document).ready(function(){ if($.browser.opera){ $('a[href]').attr('tabindex', 0); } }); ...and although this seems to work for Opera... is there a better workaround?

  • Android broswer crushes on Ajax calls, when viewport meta tag is defined

    - by Eran
    I am building a web app, which is intended to run on the Android browser. When I have a webpage that contains any kind of viewport meta tag, like this: <meta name="viewport" content="width=400"/> My webpage crushes on ajax calls. It happens when using the emulator, the actual browser on my nexus one, and on a droid (all running Android 2.1). Without the meta tag, the ajax calls run as they should. Any ideas?

  • Problem with detecting the value of the drop down list on the server (servlet) side

    - by Harry Pham
    Client code is pretty simple: <form action="DDServlet" method="post"> <input type="text" name="customerText"> <select id="customer"> <option name="customerOption" value="3"> Tom </option> <option name="customerOption" value="2"> Harry </option> </select> <input type="submit" value="send"> </form> Here is the code on the Servlet Enumeration paramNames = request.getParameterNames(); while(paramNames.hasMoreElements()){ String paramName = (String)paramNames.nextElement(); //get the next element System.out.println(paramName); } When I print out, I only see, customerText, but not customerOption. Any idea why guys? What I hope is, if I select Tom in my option, once I submit, on my servlet I should able to do this: String paramValues[] = request.getParameterValues(paramName); and get back value of 3

  • Upload large files via a webpage

    - by Hultner
    What way is the best way to let users upload large files from there webbrowser to a server. I'm talking 200MB+ possible up to a few gigatyes. I have been thinking of a few possible solutions to the problem (not tried them yet) and this is basically the things I came up with. Server download speed will not be a problem but the users connection possibly could. Having some sort of applet on the client side written in Java or Flash which sends the file in parts (is this possible with an applet) to a php/other script on the server and a checksum+ some other info about the file. On the server scripts all the parts and the info file is saved in a temporary directory wich has a unique name based on the checksum of the file and the ip of the user. When the last chunk is sent the applet sends a signal to the server saying it's finished and the server put the file together in the right location. If a chunk doesn't match the checksum for that part the server will send a response to the applet telling it to reupload that chunk. I don't know how important the checksum checking is since it's all tcpackages, someone with more insigth migth be able to answer on that. This is probably the worst way, changing the settings on your server to allow huge fileuploads via an inputfiel. Do it like a normal transfer. User an uploadmanager which does pretty much the same thing as applet i mentioned above. Pros of the first is probably that it would most likely be rather secure, you could show progress as well and possibly resume an upload if ip hasn't changed and do a threaded upload of the chunks. Cons of the first is that the user will need flash/java for it to work. Pros of the 2nd is that it will pretty much work for everyone but cons are big, first there's no way resuming an intruppted download and if something is wrong the whole file would have to be reuploaded is a few of cons. For the third one the pros is pretty muc the same as for the first but the cons is that the user would have to download an application to their computer and run and the application will have to be have to be compatible with their computer and OS. Another way may be a combination of two. Lets say an applet for bigger or more files and a simple input which is rather restricted to maybe max 10-20MB for smaller files and comability. There are probably other much smarter ways to tackle this and that's why I'm asking for advice here on SO.

  • Highlighting effect to text and/or image similar to be synchronized with audio

    - by Irfan Mulic
    I am looking how to approach following problem: We have application that displays text with audio recorded material. We use Browser Control (Internet Explorer) in Delphi App to do this. We respond to events in Delphi code setting innerHTML for elements if we have to update the style ... Now, request is to add option to dynamically move the cursor or dynamically highlight the words spoken from the paragraph. It doesn't need to match absolutely the exact word spoken so we will have to dynamically update the content of position of highlighted word based on some timer or something (because it is not text to speach). What should be the most practical and easy approach to this kind of problem, all answers are greatly appreciated. Thanks.

  • Should We Mask Passwords?

    - by Abi Noda
    From Jacob Nielson's "Stop Password Masking": Usability suffers when users type in passwords and the only feedback they get is a row of bullets. Typically, masking passwords doesn't even increase security, but it does cost you business due to login failures. What do you guys think?

  • jquery IE Fadein and Fadeout Opacity

    - by Tom
    Hi Guys, I am getting this weird problem in IE with a CSS Overlay I am applying for a lightbox. Basically, I use fadein and fadeout for jquery - the problem is that everything works fine EXCEPT in IE. In IE - I get no fadein - rather it just goes straight to opacity background. On fadeout - it removes the "opacity" for < 1 sec second and renders the page a "solid color" before removing the overlay. Anyone know how to fix this bug ? Its really annoying - I am using all the correct filters etc its just the fadein and fadeout in IE ? Thx

  • Give style attributes to sub-elements inside a <style> tag?

    - by Giffyguy
    My <style> for thumbnails currently looks like this: <style type="text/css"> img.TN { width: 100%; margin-bottom: 5.294%; cursor: pointer; } </style> This is annoying, because I have to apply this style to every single thumbnail image individually, when there could be any number of them on the screen at any given time. All of the thumbnails are inside a single <div> that groups them together, and I'd like to apply a single style to the <div> that will push the attributes I need down to all of the the <img> elements nested inside, regardless how many thumbnails there are. I'm using ASP.NET 2.0, and CSS 2.0 Does anyone know how to do this? Thanks!

  • CSS Transform offset varies with text length

    - by Mr. Polywhirl
    I have set up a demo that has 5 floating <div>s with rotated text of varying length. I am wondering if there is a way to have a CSS class that can handle centering of all text regardless of length. At the moment I have to create a class for each length of characters in my stylesheet. This could get too messy. I have also noticed that the offsets get screwd up is I increase or decrease the size of the wrapping <div>. I will be adding these classes to divs through jQuery, but I still have to set up each class for cross-browser compatibility. .transform3 { -webkit-transform-origin: 65% 100%; -moz-transform-origin: 65% 100%; -ms-transform-origin: 65% 100%; -o-transform-origin: 65% 100%; transform-origin: 65% 100%; } .transform4 { -webkit-transform-origin: 70% 110%; -moz-transform-origin: 70% 110%; -ms-transform-origin: 70% 110%; -o-transform-origin: 70% 110%; transform-origin: 70% 110%; } .transform5 { -webkit-transform-origin: 80% 120%; -moz-transform-origin: 80% 120%; -ms-transform-origin: 80% 120%; -o-transform-origin: 80% 120%; transform-origin: 80% 120%; } .transform6 { -webkit-transform-origin: 85% 136%; -moz-transform-origin: 85% 136%; -ms-transform-origin: 85% 136%; -o-transform-origin: 85% 136%; transform-origin: 85% 136%; } .transform7 { -webkit-transform-origin: 90% 150%; -moz-transform-origin: 90% 150%; -ms-transform-origin: 90% 150%; -o-transform-origin: 90% 150%; transform-origin: 90% 150%; } Note: The offset values I set were eye-balled. Update Although I would like this handled with a stylesheet, I believe that I will have to calculate the transformations of the CSS in JavaScript. I have created the following demo to demonstrate dynamic transformations. In this demo, the user can adjust the font-size of the .v_text class and as long as the length of the text does not exceed the .v_text_wrapper height, the text should be vertically aligned in the center, but be aware that I have to adjust the magicOffset value. Well, I just noticed that this does not work in iOS...

Which layout is best for usability, possible ad placements, widget integration?

  • Does form with enctype="multipart/form-data" cause problems accessing a hidden field

    I have created a hidden form element <form name="UploadImage" enctype="multipart/form-data" method="post" action="UploadImage"> <label> </label> <input name="imgUploadObjId" id="imgUploadObjId" value="52" type="hidden"> //rest of the form here </form> And I am trying to get the value with this line in a servlet (as I have done before): int objId = Integer.parseInt(request.getParameter("imgUploadObjId")); But I get this (line 33 is the line above): java.lang.NumberFormatException: null java.lang.Integer.parseInt(Unknown Source) java.lang.Integer.parseInt(Unknown Source) web.objects.UploadImage.doPost(UploadImage.java:33) javax.servlet.http.HttpServlet.service(HttpServlet.java:637) javax.servlet.http.HttpServlet.service(HttpServlet.java:717) Is there something different about a form with enctype="multipart/form-data"? Or can you see some other error.

  • Textarea to paragraphs

    - by zaf
    When I have to render textarea content to the front end I usually pass it thru a function that converts newlines to <br/> tags and double newlines signal paragraph tags so blocks of text get surrounded by <p> and </p> tags. To save time I usually use a ready made PHP function from the wordpress codebase. You can get the link from the man himself: http://ma.tt/scripts/autop/ If you check it out you'll see it does some heavy lifting with about 20 regular expressions. I know I could use a wysiwyg editor (like TinyMCE or CKEditor) that can format the data on the client and then send it to the server (most of them add <p>..</p> tags by default) but I want to know the experience of others in handling raw textarea input and then displaying it on the front end.
