  • how to create box with sliding linked images

    - by paracaudex
    Where can I read more about creating linked slides like at the top of nytimes.com, slate.com, yahoo.com, nyu.edu, etc. I assume it's javascript, but I'm not sure what it's called, so I'm not sure how to look it up. I want to create a box at the top of a website with blocks of html text which slide in sequence if the user clicks next or after a certain amount of time. Where can I read more about this?

  • CSS/JS: Evenly spreading elements across multiple lines

    - by David Lawson
    How would you go about evenly spreading elements across multiple lines, for example: wrapper div: <div style="text-align: center"> elements inside: <div style="display: inline-block; padding-left: 10px; padding-right: 10px;">Element</div> Instead of only having one element on the next line (wrapped): Element 1 Element 2 Element 3 Element 4 Element 5 Element 6 It does this, spreading out the elements: Element 1 Element 2 Element 3 Element 4 Element 5 Element 6

  • Selecting a date value from a dynamically generated listbox.

    - by ziggy
    Hi All, I have a listbox whose values are generated dynamically. The list box contains months and years and when generated looks like this. <select name="arr_dtm_mon_year" tabindex="150" class="input"> <option value=""></option> <option value="NOV 09">Nov 09</option> <option value="DEC 09">Dec 09</option> <option value="JAN 10">Jan 10</option> <option value="FEB 10">Feb 10</option> <option value="MAR 10">Mar 10</option> <option value="APR 10">Apr 10</option> <option value="MAY 10">May 10</option> <option value="JUN 10" selected>Jun 10</option> <option value="JUL 10">Jul 10</option> <option value="AUG 10">Aug 10</option> <option value="SEP 10">Sep 10</option> <option value="OCT 10">Oct 10</option> </select> The element in the listbox that is by default selected is the current month. When i use selenium IDE to select from this listbox it works fine. Here are example commands i use to select from the listbox. <tr> <td>select</td> <td>arr_dtm_mon_year</td> <td>label=Oct 10</td> </tr> <tr> <td>select</td> <td>arr_dtm_mon_year</td> <td>label=May 10</td> </tr> Now the problem i have is the values in the listbox is dynamically generated. In the above example i selected the option for "May 10". The values that are generated is a list of all previous six months and a list of all future six months. This basically means that if i rerun the test 6 months from now "May 10" will not be available from the list. Is it possible to select the value dynamically. For example can i first calculate the current month and select the value with that is current month + 1 (i.e. next month). And also how can i build the value to be selected after i have determined what the next month is. Any help will be greatly appreciated.

  • CI pagination, POST problem

    - by Gwood
    Okay, I am pretty new in CI and I am stuck on pagination. I am performing this pagination on a record set that is result of a query. Now everything seems to be working fine. But there’s some problem probably with the link. I am displaying 10 results per page. Now if the results are less than 10 then it’s fine. Or If I pull up the entire records in the table it works fine. But in case the result is more than 10 rows, then the first 10 is perfectly displayed, and when I click on the pagination link to get to the next page the next page displays the rest of the results from the query as well as, other records in the table. ??? I am confused.. Any help?? Here’s the model code I am using .... function getTeesLike($field,$param) { $this-db-like($field,$param); $this-db-limit(10, $this-uri-segment(3)); $query=$this-db-get(‘shirt’); if($query-num_rows()0){ return $query-result_array(); } } function getNumTeesfromQ($field,$param) { $this-db-like($field,$param); $query=$this-db-get(‘shirt’); return $query-num_rows(); } And here’s the controller code .... $KW=$this-input-post(‘searchstr’); $this-load-library(‘pagination’); $config[‘base_url’]=‘http://localhost/cit/index.php/tees/show/’; $config[‘total_rows’]=$this-T-getNumTeesfromQ(‘Title’,$KW); $config[‘per_page’]=‘10’; $this-pagination-initialize($config); $data[‘tees’]=$this-T-getTeesLike(‘Title’,$KW); $data[‘title’]=‘Displaying Tees data’; $data[‘header’]=‘Tees List’; $data[‘links’]=$this-pagination-create_links(); $this-load-view(‘tee_res’, $data); //What am I doing wrong here ???? Pls help ... I guess the problem is with the $KW=$this-input-post(‘searchstr’); .. Because if I hard code a value for $KW it works fine. May be I should use POST differently ..but how do I pass the value from the form without POSTING it , its CI so not GET ... ??????

  • How can I pre-compress files with mod_deflate in Apache 2.x?

    - by Otto
    I am serving all content through apache with Content-Encoding: zip but that compresses on the fly. A good amount of my content is static files on the disk. I want to gzip the files beforehand rather than compressing them every time they are requested. This is something that, I believe, mod_gzip did in Apache 1.x automatically, but just having the file with .gz next to it. That's no longer the case with mod_deflate.

  • Cocoa-Touch framework for speaking to a TCP socket?

    - by Coocoo4Cocoa
    I have a daemon running on a server that's latched onto a TCP/IP port. I'm looking to see if there's currently any support iPhone/Cocoa-touch frameworks that gives a nice OO wrapper for speaking to the daemon over an IP socket. I need to be able to interactively query the daemon with commands and retrieve back information. If there isn't any OO wrappers for such a task, what's the next best bet?

    - by CodeBuddy
    I've started experimenting with Hudson as a build server. I'm using subversion and have it configured to poll every minute. The issue I'm seeing is that if a build at revision 10 takes 5 minutes and there are 5 commits during that time, Hudson will next build revision 15. Is there a way to ensure every revision is built?

  • Make a Button Appear Focused When Not

    - by Bret
    The Find and Replace dialog in Visual Studio is a perfect example of what im trying to accomplish. Notice how the "Find what" text field has keyboard focus but the "Find Next" button appears bluish as if it has keyboard focus also even though it does not. How can I accomplish this myself? I've tried messing with FocusManager and Focus Scopes without much luck. I suspect i may be barking up the wrong tree? Any advice is appreciated! Thanks
