  • Javascript handling textarea

    - by bbenton
    Hi all, I'm a bit new to Javascript and am trying to create a delimited string from a textare. The problem is when passing in the textarea, it adds newlines for each row on the textarea. I need to have the entire textarea parsed into a string with a delimiter for each line (replacing the newline char). So for example, if you passed in a textarea with the following lines (which is also how it looks when using the alert function): abcd efgh ijkl It would look like: abcd-efgh-ijkl after parsing. function submitToForm(form) { var param_textarea = form.listofplugins.value; var test = param_textarea.replace(/\\r?\\n/, /:/) alert(test); } Thanks a lot!

  • JS / JQuery character problem

    - by Jimmy Farax
    I have a code which has a character that JS is not handling properly. $(document).ready(function(){ $.getJSON("http://sjama.tumblr.com/api/read/json?callback=?", function (data){ for (var i=0; i<data.posts.length; i++){ var blog = data.posts[i]; var id = blog.id; var type = blog.type; var photo = blog.photo-url-250; if (type == "photo"){ $("#blog_holder").append('<div class="blog_item_holder"><div class="blog_item_top"><img src='+photo+'/></div><div class="blog_item_bottom">caption will go here</div></div>'); } } }); <!-- end $.getJSON }); The problem is with this line: var photo = blog.photo-url-250; after "blog." it reads the "url" part weirdly because of the dash (-) in between. What can I do to sort this problem out?

  • Disable link with the prototype observe method...

    - by enyo
    I want to create a link like this: <a href="http://example.com">text</a> and replace the behavior so that the link downloads the content with Ajax instead when clicking. It is important for me not to replace the href attribute (so copying the link still works). One solution would be to do: $('link').onclick = function() { return false; }; but I would like to use the .observe method. But this doesn't work: $('link').observe('click', function() { return false; }); (which is quite logical). Any ideas on how I could achieve this? Thanks.

  • exportDocument() 'destination folder does not exist' error

    - by dvb
    I'm trying to make a script in photoshop that will modify some layers and than export them as a PNG image. I've copied the following code from another place: function SavePNG(saveFile){ var pngOpts = new ExportOptionsSaveForWeb; pngOpts.format = SaveDocumentType.PNG pngOpts.PNG8 = false; pngOpts.transparency = true; pngOpts.interlaced = true; pngOpts.quality = 100; activeDocument.exportDocument(saveFile,ExportType.SAVEFORWEB,pngOpts); } The function export the active document of photoshop to the file specified by the saveFile parameter. It's working fine with simple paths like 'C:\images\result.png' but when trying with different paths like '~/Desktop/' or paths with some special characters the file isn't exported, and a 'destination folder does not exist' error massage appear. Any idea how can I solve it?

  • How do I create a view with a picker on the bottom and a table view on the top?

    - by Andy
    Hi - first time asker, long-time lurker. I am trying to create an iPhone view that has a date/time picker on the bottom half of the screen, and a grouped, single-section, four-row table view on the top half of the screen (almost identical to the one Apple shows in Fig. 2-4 of their View Controller Programming Guide (but then never goes on to explain). Conceptually, I think I understand that what I need is a main view with a pair of subviews - one for the picker, and one for the table view. I'm pretty sure I can make the picker function once I have it on-screen, and I'm pretty sure I can make the table view function too. What I can't for the life of me figure out is how, programmatically speaking, to get the two views onto the screen simultaneously. I can lay it out perfectly in Interface Builder, but then it all goes to hell when I switch to Xcode...the view appears with the picker, but no table view. Thanks, in advance, for any help you can offer.

  • Python json memory bloat

    - by Anoop
    import json import time from itertools import count def keygen(size): for i in count(1): s = str(i) yield '0' * (size - len(s)) + str(s) def jsontest(num): keys = keygen(20) kvjson = json.dumps(dict((keys.next(), '0' * 200) for i in range(num))) kvpairs = json.loads(kvjson) del kvpairs # Not required. Just to check if it makes any difference print 'load completed' jsontest(500000) while 1: time.sleep(1) Linux top indicates that the python process holds ~450Mb of RAM after completion of 'jsontest' function. If the call to 'json.loads' is omitted then this issue is not observed. A gc.collect after this function execution does releases the memory. Looks like the memory is not held in any caches or python's internal memory allocator as explicit call to gc.collect is releasing memory. Is this happening because the threshold for garbage collection (700, 10, 10) was never reached ? I did put some code after jsontest to simulate threshold. But it didn't help.

  • dynamically embedding youtube videos with jquery

    - by danwoods
    Hello all, I'm trying to retrieve a listing of a user's youtube videos and embed them in a page using jQuery. My code looks something like this: $(document).ready(function() { //some variables var fl_obj_template = $('<object width="260" height="140">' + '<param name="movie" value=""></param>' + '<param name="allowFullScreen" value="true"></param>' + '<param name="allowscriptaccess" value="always"></param>' + '<embed src="" type="application/x-shockwave-flash" allowscriptaccess="always" allowfullscreen="true" width="260" height="140"></embed>' + '</object>'); var video_elm_arr = $('.video'); //hide videos until ready $('.video').addClass('hidden'); //pull video data from youtube $.ajax({ url: 'http://gdata.youtube.com/feeds/api/users/username/uploads?alt=json', dataType: 'jsonp', success: function(data) { $.each(data.feed.entry, function(i,item){ //only take the first 7 videos if(i > 6) return; //give the video element a flash object var cur_flash_obj = fl_obj_template; //assign title $(video_elm_arr[i]).find('.video_title').html(item.title.$t); //clean url var video_url = item.media$group.media$content[0].url; var index = video_url.indexOf("?"); if (index > 0) video_url = video_url.substring(0, index); //and asign it to the player's parameters $(cur_flash_obj).find('object param[name="movie"]').attr('value', video_url); $(cur_flash_obj).find('object embed').attr('src', video_url); //alert(cur_flash_obj); //insert flash object in video element $(video_elm_arr[i]).append(cur_flash_obj); //and show $(video_elm_arr[i]).removeClass('hidden'); }); } }); }); (of course with 'username' being the actual username). The video titles appear correctly but no videos show up. What gives? The target html looks like: <div id="top_row_center" class="video_center video"> <p class="video_title"></p> </div>

  • Is recursion preferred compare to iteration in multicore era?

    - by prM
    Or say, do multicore CPUs process recursion faster than iteration? Or it simply depends on how one language runs on the machine? like c executes function calls with large cost, comparing to doing simple iterations. I had this question because one day I told one of my friend that recursion isn't any amazing magic that can speed up programs, and he told me that with multicore CPUs recursion can be faster than iteration. EDIT: If we consider the most recursion-loved situation (data structure, function call), is it even possible for recursion to be faster?

  • Jquery, checkboxes and isChecked

    - by Ben
    When I bind a function to a checkbox element like: $("#myCheckbox").click( function() { alert($(this).is(":checked")); }); The checkbox changes it checked attribute before the event is triggered, it's it normal behavior, thus giving and inverse result. However, when I do: $("#myCheckbox").click(); The checkbox changes it checked attribute after the event is triggered. My question is, is there a way to trigger the click event from jquery like a normal click would do (first scenario)? PS: I've already tried with trigger('click');

  • Subtracting Delphi Time Ranges from a Date Range, Calculate Remaining Time

    - by Anagoge
    I'm looking for an algorithm that will help calculate a workday working time length. It would have an input date range and then allow subtracting partially or completely intersecting time range slices from that date range and the result would be the number of minutes (or the fraction/multiple of a day) left in the original date range, after subtracting out the various non-working time slices. For Example: Input date range: 1/4/2010 11:21 am - 1/5/2010 3:00 pm Subtract out any partially or completely intersecting slices like this: Remove all day Sunday Non-Sundays remove 11:00 - 12:00 Non-Sundays remove time after 5:00 pm Non-Sundays remove time before 8:00 am Non-Sundays remove time 9:15 - 9:30 am Output: # of minutes left in the input date range I don't need anything overly-general. I could hardcode the rules to simplify the code. If anyone knows of sample code or a library/function somewhere, or has some pseudo-code ideas, I'd love something to start with. I didn't see anything in DateUtils, for example. Even a basic function that calculates the number of minutes of overlap in two date ranges to subtract out would be a good start.

  • How do I use compiler intrinsic __fmul_?

    - by Eric Thoma
    I am writing a massively parallel GPU application. I have been optimizing it by hand. I received a 20% performance increase with _fdividef(x, y), and according to The Cuda C Programming Guide (section C.2.1), using similar functions for multiplication and adding is also beneficial. The function is stated as this: "_fmulrn,rz,ru,rd". __fdividef(x,y) was not stated with the arguments in brackets. I was wondering, what are those brackets? If I run the simple code: int t = __fmul_(5,4); I a compiler error about how _fmul is undefined. I have the CUDA runtime included, so I don't think it is a setup thing; rather it is something to do with those square brackets. How do I correctly use this function? Thank you.

  • Getting Postfix to process the mail queue on Mac OS X

    - by paperclip
    I'm in the process of getting Sendmail/Postfix setup so that I can send and test my PHP scripts when using the mail() function. I've got to the point that when I run the mail() function in PHP, the script executes without any errors and the mail is sent to my mailq but it then does not get processed and simply times-out with a message of: Operation timed out.

  • PHP - error when insert date into MySQL

    - by Michael Mao
    Hello everyone: I've got a typical problem when trying to insert a date into MySQL. The column defined in MySQL is of type DATE. My PHP version is 5.3.0 Apart from this date-related issue, the rest of my code works just fine. And this is my PHP script to do this: $tablename = BOOKS_TABLE; $insert = mysql_query("INSERT INTO $tablename (barcode, book_name, volume_num,". " author, publisher, item_type, buy_price, buy_date) VALUES ". "(". "'" . $barcode . "', ". "'" . $bookname . "', ". "'" . $volumenum . "', ". "'" . $author . "', ". "'" . $publisher . "', ". "'" . $itemtype . "', ". "'" . $buyprice . "', ". "'" . getMySQLDateString($buydate). //"'STR_TO_DATE('".$buydate ."', '%d/%m/%Y'))'". //nothing changes in MySQL ")"); And this is the faulty function : function getMySQLDateString($buydate) //typical buydate : 04/21/2009 { $mysqlDateString = date('Y-m-d H:i:s', $strtotime($buydate)); return $mysqlDateString; } The first commented out line wouldn't do anything, the script is executed with no error, however, there is nothing changed in datebase after this. The current approach will cause a Fatal error saying function name must be a string in this line. Actually I followed this thread on SO, but just cannot pass the date into MySQL... Can anyone help me figure out which part is not right? How would you do it, in this case, to get it right? Sorry about such a journeyman-like question, thanks a lot in advance.

  • dragging components in flex

    - by SuperString
    so I am trying to drag around some images in a canvas. I am adding eventlisteners to the components and calling startDrag() and stopDrag() to pick them up and stuff: component.addEventListener(MouseEvent.MOUSE_DOWN, component.startDrag) The problem is that it is selecting the image at its (0,0) location and not where I initially click on it. So there's a sudden "jump" when I click on the image. It is not smooth. I noticed that startDrag() has two default parameters, one of them is lockCenter and it is default to false. Maybe do I set it equal to true somehow? (I don't know how to pass arguments to my second parameter in addeventlistener) Another question: if I want to add more conditions to it, like make a new function that uses component.startDrag(), how do I pass the component to this function while adding event listener to it at the same time? for example: I want to do: component.addEventListener(MouseEvent.MOUSE_DOWN, some_other_function); where some_other_function uses component.startDrag(); Thanks!

  • Embedded C++, any tips to avoid a local thats only used to return a value on the stack?

    - by lisarc
    I have a local that's only used for the purposes of checking the result from another function and passing it on if it meets certain criteria. Most of the time, that criteria will never be met. Is there any way I can avoid this "extra" local? I only have about 1MB of storage for my binary, and I have several thousand function calls that follow this pattern. I know it's a minor thing, but if there's a better pattern I'd love to know! SomeDataType myclass::myFunction() { SomeDataType result; // do I really need this local??? // i need to check the result and pass it on if it meets a certain condition result = doSomething(); if ( ! result ) { return result; } // do other things here ... // normal result of processing return SomeDataType(whatever); }

  • Rails: Converting from MySQL to PostGres breaks Geokit Distance Calculations???

    - by Kevin
    I recently switched my database from MySQL to PostGres. I also use GeoKit. When I started my app up with the new database already seeded, I get the following error: PGError: ERROR: function radians(character varying) does not exist LINE 1: ...COS(0.661045389762993)*COS(-2.12957994527573)*COS(RADIANS(ti... ^ HINT: No function matches the given name and argument types. You might need to add explicit type casts. Anyone know why this is breaking now? I know GeoKit still works because it's still performing the geocoding in the model per ticket when the database is seeded, it just won't do the distance calculations correctly.

  • Why is passing a string literal into a char* arguament only sometimes a compiler error?

    - by Brian Postow
    I'm working in a C, and C++ program. We used to be compiling without the make-strings-writable option. But that was getting a bunch of warnings, so I turned it off. Then I got a whole bunch of errors of the form "Cannot convert const char* to char* in argmuent 3 of function foo". So, I went through and made a whole lot of changes to fix those. However, today, the program CRASHED because the literal "" was getting passed into a function that was expecting a char*, and was setting the 0th character to 0. It wasn't doing anything bad, just trying to edit a constant, and crashing. My question is, why wasn't that a compiler error? In case it matters, this was on a mac compiled with gcc-4.0.
