  • Form:has selector does not work on IE

    - by Joel
    Hey, I am trying to use "form:has" selector which works on Chrome but not on IE. http://jsbin.com/uvumu/2 Does anyone have any idea why it is not working on IE? (when pushing the Post button there should be an alert box) Edited: Here is the code: JS: $(document).ready(function() { $(".comment-link").live('click',function() { return false; }); $("#morefeeds-link").click(function () { return false; }); // Form submittion - doesnt work $("form:has(.commentBtn)").live('submit',function () { alert("a"); return false; }); return false; });? HTML <form> <a href="#" class="comment-link" style="font-size:12px;">Comment</a> <table border="0" cellpadding="0" cellspacing="0"> <tr> <td valign="middle"> <input type="hidden" name="commentkey" value="1"> <input type="text" name="commenttext" class="commentfocus" value="Express your opinion"> </td> <td valign="middle"><input type="submit" class="commentBtn" value="Post"></td> </tr> </table> </form>

  • Size of assosiation in Hibernate criteria.

    - by trnl
    Hello guys. I've faced with a problem when querying with Hibernate Criteria in Grails. Take a look: def visitors = Client.withCriteria{ visits{ use ( TimeCategory ) {between('date',date,date+1.month-1)} } sizeGe("visits",params.from) sizeLe("visits",params.to) fetchMode("visits", FM.JOIN) }; I need only those clients, which has number of visits in month between from and to bounds. But now size* restrictions is being applied to all visits. So if client has one visit in this month, and visit in previous month. And if I set from=2, this client will be in result. But it should not be there. Any help is appreciated. Thanks, Vova.

  • How to manipulate and print a chart in MS Excel from AppleScript?

    - by Stu Thompson
    With an existing chart in a MS Excel for Mac 2008, in AppleScript, I am trying to do two things: Rotate a 3D chart 1° Save the chart as a image (png) From what I've found on the Intertubes, it seems possible. But AppleScript's awkward verbosity and the lack of non-trivial MS Excel AppleScript examples on the web are too much for me to overcome. Just for the saving part, this is what I have so far: tell application "Microsoft Excel" activate object worksheet "iozone-16" set cht to chart object 1 of active sheet tell cht #save as chart object [picture type enumeration] [file name Unicode text] #Argh!!! end tell end tell The 'rotate 1°' task seems to involve "internal objects", but that is as far as I've gotten.

  • How do i write this jpql query? java

    - by Nitesh Panchal
    Hello, Say i have 5 tables, tblBlogs tblBlogPosts tblBlogPostComment tblUser tblBlogMember BlogId BlogPostsId BlogPostCommentId UserId BlogMemberId BlogTitle BlogId CommentText FirstName UserId PostTitle BlogPostsId BlogId BlogMemberId Now i want to retrieve only those blogs and posts for which blogMember has actually commented. So in short, how do i write this plain old sql :- Select b.BlogTitle, bp.PostTitle, bpc.CommentText from tblBlogs b Inner join tblBlogPosts bp on b.BlogId = bp.BlogId Inner Join tblBlogPostComment bpc on bp.BlogPostsId = bpc.BlogPostsId Inner Join tblBlogMember bm On bpc.BlogMemberId = bm.BlogMemberId Where bm.UserId = 1; As you can see, everything is Inner join, so only that row will be retrieved for which the user has commented on some post of some blog. So, suppose he has joined 3 blogs whose ids are 1,2,3 (The blogs which user has joined are in tblBlogMembers) but the user has only commented in blog 2 (of say BlogPostId = 1). So that row will be retrieved and 1,3 won't as it is Inner Join. How do i write this kind of query in jpql? In jpql, we can only write simple queries like say :- Select bm.blogId from tblBlogMember Where bm.UserId = objUser; Where objUser is supplied using :- em.find(User.class,1); Thus once we get all blogs(Here blogId represents a blog object) which user has joined, we can loop through and do all fancy things. But i don't want to fall in this looping business and write all this things in my java code. Instead, i want to leave that for database engine to do. So, how do i write the above plain sql into jpql? and what type of object the jpql query will return? because i am only selecting few fields from all table. In which class should i typecast the result to? I think i posted my requirement correctly, if i am not clear please let me know. Thanks in advance :).

  • Event to listen to attribute changes

    - by Luis
    I dont think this is possible but maybe someone knows a way to achieve this. I want to attach an event to an html element to listen to attribute change. So say for instance that I want something to happen when a visibility of a div changes. The reason is that I have no control over the javascript that is switching the visibility, hence the need for an event. Thanks

  • Ubuntu login takes 15 seconds, "I/O error dev fd0 sector 0"

    - by Dan
    After upgrading to Ubuntu 10.04, when I first login it takes 10+ seconds where it just sits at the gdm backgroup before taking me to gnome. By switching to a terminal window during this 10 seconds I saw the error message "I/O error /dev/fd0 sector 0" being outputted. I assume this has to do with the floppy drive... but I don't even have a floppy drive! How do I disable this device and make this error message go away (and hopefully fix the long wait)? Thanks.

  • PHP simplexml and xpath

    - by FFish
    I have an XML file like this: <?xml version="1.0" encoding="UTF-8"?> <gallery> <album tnPath="tn/" lgPath="imm/" fsPath="iml/" > <img src="001.jpg" /> <img src="002.jpg" /> </album> </gallery> I am reading the file with: $xmlFile = "xml.xml"; $xmlStr = file_get_contents($xmlFile . "?" . time()); $xmlObj = simplexml_load_string($xmlStr); Now I am rebuilding the XML file and would like to save the album node with it's attributes in a var I was thinking with xpath: // these all return arrays with the images... // echo $xmlObj->xpath('/gallery/album@tnPath'); // echo $xmlObj->xpath('//album[@tnPath]'); // echo $xmlObj->xpath('//@tnPath'); But that doesn't seem to work? Any help?

  • Problem with auto increment primary key (MySQL).

    - by mathon12
    I have 2 tables each using other's primary key as a foreign key. The primary keys for both are set to auto_increment. The problem is, when I try to create and entry into one of the tables, I have no idea what the primary key of the entry is and can't figure out what to put in the other table as a foreign key. What should I do? Do I drop auto_increment altogether and cook up a unique identifier for each entry so I can use it to address the created entries? I'm using PHP, if that's relevant. Thanks.

  • Using PHP interfaces in Codeigniter

    - by John Stewart
    I am trying to find out how can I used PHP interfaces in my MVC design. I want to make sure that the design enforces an interface so that any new module would follow that. For example: <?php interface BaseAPI { public function postMessage($msg); } class ServiceAPI implements BaseAPI { public function postMessage($msg) { return $msg; } } class Service_Two_API implements BaseAPI { public function postMessage($msg) { return "can't do this: ".$msg; } } ?> I want to do this in CI. Is it possible? how should I design it?

  • Where is the virtual function call overhead?

    - by Semen Semenych
    Hello everybody, I'm trying to benchmark the difference between a function pointer call and a virtual function call. To do this, I have written two pieces of code, that do the same mathematical computation over an array. One variant uses an array of pointers to functions and calls those in a loop. The other variant uses an array of pointers to a base class and calls its virtual function, which is overloaded in the derived classes to do absolutely the same thing as the functions in the first variant. Then I print the time elapsed and use a simple shell script to run the benchmark many times and compute the average run time. Here is the code: #include <iostream> #include <cstdlib> #include <ctime> #include <cmath> using namespace std; long long timespecDiff(struct timespec *timeA_p, struct timespec *timeB_p) { return ((timeA_p->tv_sec * 1000000000) + timeA_p->tv_nsec) - ((timeB_p->tv_sec * 1000000000) + timeB_p->tv_nsec); } void function_not( double *d ) { *d = sin(*d); } void function_and( double *d ) { *d = cos(*d); } void function_or( double *d ) { *d = tan(*d); } void function_xor( double *d ) { *d = sqrt(*d); } void ( * const function_table[4] )( double* ) = { &function_not, &function_and, &function_or, &function_xor }; int main(void) { srand(time(0)); void ( * index_array[100000] )( double * ); double array[100000]; for ( long int i = 0; i < 100000; ++i ) { index_array[i] = function_table[ rand() % 4 ]; array[i] = ( double )( rand() / 1000 ); } struct timespec start, end; clock_gettime(CLOCK_PROCESS_CPUTIME_ID, &start); for ( long int i = 0; i < 100000; ++i ) { index_array[i]( &array[i] ); } clock_gettime(CLOCK_PROCESS_CPUTIME_ID, &end); unsigned long long time_elapsed = timespecDiff(&end, &start); cout << time_elapsed / 1000000000.0 << endl; } and here is the virtual function variant: #include <iostream> #include <cstdlib> #include <ctime> #include <cmath> using namespace std; long long timespecDiff(struct timespec *timeA_p, struct timespec *timeB_p) { return ((timeA_p->tv_sec * 1000000000) + timeA_p->tv_nsec) - ((timeB_p->tv_sec * 1000000000) + timeB_p->tv_nsec); } class A { public: virtual void calculate( double *i ) = 0; }; class A1 : public A { public: void calculate( double *i ) { *i = sin(*i); } }; class A2 : public A { public: void calculate( double *i ) { *i = cos(*i); } }; class A3 : public A { public: void calculate( double *i ) { *i = tan(*i); } }; class A4 : public A { public: void calculate( double *i ) { *i = sqrt(*i); } }; int main(void) { srand(time(0)); A *base[100000]; double array[100000]; for ( long int i = 0; i < 100000; ++i ) { array[i] = ( double )( rand() / 1000 ); switch ( rand() % 4 ) { case 0: base[i] = new A1(); break; case 1: base[i] = new A2(); break; case 2: base[i] = new A3(); break; case 3: base[i] = new A4(); break; } } struct timespec start, end; clock_gettime(CLOCK_PROCESS_CPUTIME_ID, &start); for ( int i = 0; i < 100000; ++i ) { base[i]->calculate( &array[i] ); } clock_gettime(CLOCK_PROCESS_CPUTIME_ID, &end); unsigned long long time_elapsed = timespecDiff(&end, &start); cout << time_elapsed / 1000000000.0 << endl; } My system is LInux, Fedora 13, gcc 4.4.2. The code is compiled it with g++ -O3. The first one is test1, the second is test2. Now I see this in console: [Ignat@localhost circuit_testing]$ ./test2 && ./test2 0.0153142 0.0153166 Well, more or less, I think. And then, this: [Ignat@localhost circuit_testing]$ ./test2 && ./test2 0.01531 0.0152476 Where are the 25% which should be visible? How can the first executable be even slower than the second one? I'm asking this because I'm doing a project which involves calling a lot of small functions in a row like this in order to compute the values of an array, and the code I've inherited does a very complex manipulation to avoid the virtual function call overhead. Now where is this famous call overhead?

  • Why the vertical scroll bar moves automatically ?

    I don't understand why the vertical scroll bar moves automatically to the most top position when "Line 9" clicked, for example. Further clicks does not move the scroll bar.
