  • Unique element ID, even if element doesn't have one

    - by Robert J. Walker
    I'm writing a GreaseMonkey script where I'm iterating through a bunch of elements. For each element, I need a string ID that I can use to reference that element later. The element itself doesn't have an id attribute, and I can't modify the original document to give it one (although I can make DOM changes in my script). I can't store the references in my script because when I need them, the GreaseMonkey script itself will have gone out of scope. Is there some way to get at an "internal" ID that the browser uses, for example? A Firefox-only solution is fine; a cross-browser solution that could be applied in other scenarios would be awesome. Edit: If the GreaseMonkey script is out of scope, how are you referencing the elements later? They GreaseMonkey script is adding events to DOM objects. I can't store the references in an array or some other similar mechanism because when the event fires, the array will be gone because the GreaseMonkey script will have gone out of scope. So the event needs some way to know about the element reference that the script had when the event was attached. And the element in question is not the one to which it is attached. Can't you just use a custom property on the element? Yes, but the problem is on the lookup. I'd have to resort to iterating through all the elements looking for the one that has that custom property set to the desired id. That would work, sure, but in large documents it could be very time consuming. I'm looking for something where the browser can do the lookup grunt work. Wait, can you or can you not modify the document? I can't modify the source document, but I can make DOM changes in the script. I'll clarify in the question. Can you not use closures? Closuses did turn out to work, although I initially thought they wouldn't. See my later post. It sounds like the answer to the question: "Is there some internal browser ID I could use?" is "No."

  • How to get the project version description in Jira via the Soap api

    - by Benju
    Does anybody know how to get the version description field for a Jira project? Using the ProjectService.getVersions method we can get an Array of RemoteVersion objects but these RemoteVersion objects do not contain the description field. http://docs.atlassian.com/rpc-jira-plugin/latest/com/atlassian/jira/rpc/soap/service/ProjectService.html#getVersions(com.opensymphony.user.User, java.lang.String) Will I have to expose my own web web service via a Jira plugin to get this?

  • Try-Catch or Check Length? C# XNA

    - by Shaded
    I was just wondering which would be cheaper, using a try catch block for index out of bounds or checking the length of a multi dimensional array and comparing values? I have a feeling it's the length, since I can store the length in a variable and then just do if's which are relatively cheap. I'm just not sure how expensive try-catch is. Thanks!

  • How do you display a binary search tree?

    - by fakeit
    I'm being asked to display a binary search tree in sorted order. The nodes of the tree contain strings. I'm not exactly sure what the best way is to attack this problem. Should I be traversing the tree and displaying as I go? Should I flatten the tree into an array and then use a sorting algorithm before I display? I'm not looking for the actual code, just a guide where to go next.

  • Extracting attribute data from a raster

    - by user308827
    Hi, I have a raster file (basically 2D array) with close to a million points. I am trying to extract a circle from the raster (and all the points that lie within the circle. Using ArcGIS is exceedingly slow for this. Can anyone suggest any image processing library that is both easy to learn and powerful and quick enough for something like this? Thanks!

  • Need to optimize this PHP script for "recent posts". Fatal error when post count is high...

    - by Scott B
    The code below is resulting in an error on a site in which there are ~ 1500 posts. It performs fine when post count is nominal, however, this heavy load is exposing the weakness of the code and I'd like to optimize it. Interestingly, when I disable this menu and instead use the "Recent Posts" widget, the posts are drawn fine. So I'd probably do good to borrow from that code if I knew where to find it, or better yet, If I could call the widget directly in my theme, passing it a post count variable. Fatal error: Allowed memory size of 33554432 bytes exhausted (tried to allocate 16384 bytes) in /home1/est/public_html/mysite/wp-includes/post.php on line 3462 The code is below. Its purpose is to list "recent posts". global $post; $cat=get_cat_ID('myMenu'); $cathidePost=get_cat_ID('hidePost'); $myrecentposts = get_posts(array('post_not_in' => get_option('sticky_posts'), 'cat' => "-$cat,-$cathidePost",'showposts' => $count-of-posts)); $myrecentposts2 = get_posts(array('post_not_in' => get_option('sticky_posts'), 'cat' => "-$cat,-$cathidePost",'showposts' => -1)); $myrecentpostscount = count($myrecentposts2); if ($myrecentpostscount > 0) { ?> <div class="recentPosts"><h4><?php if ($myHeading !=="") { echo $myHeading; } else { echo "Recent Posts";} ?></h4><ul> <?php $current_page_recent = get_post( $current_page ); foreach($myrecentposts as $idxrecent=>$post) { if($post->ID == $current_page_recent->ID) { $home_menu_recent = ' class="current_page_item'; } else { $home_menu_recent = ' class="page_item'; } $myclassrecent = ($idxrecent == count($myrecentposts) - 1 ? $home_menu_recent.' last"' : $home_menu_recent.'"'); ?> <li<?php echo $myclassrecent ?>><a href="<?php the_permalink(); ?>"><?php the_title(); ?></a></li> <?php } ; if (($myrecentpostscount > $count-of-posts) && $count-of-posts > -1){ ?><li><a href="<?php bloginfo('url'); ?>/recent">View All Posts</a></li><?php } ?></ul></div>

  • java double[][] - display as image

    - by joe_shmoe
    Hi all, just wondering if there is a simple way in java to display the contents of say 16x16 array of doubles [0..1] as a greyscale image (ala matlab)? using an unfamiliar matrix library, so I'd like to check that I'm on the right track. don't really care if it is slow or ugly, or if it requires external library - it's just there for a quick look, so as long as it works, I'm fine.

  • Is factory method proper design for my problem?

    - by metdos
    Hello Everyone, here is my problem and I'm considering to use factory method in C++, what are your opinions ? There are a Base Class and a lot of Subclasses. I need to transfer objects on network via TCP. I will create objects in first side, and using this object I will create a byte array TCP message, and send it to other side. On the other side I will decompose TCP message, I will create object and I will add this object to a polymorphic queue.

  • Regex for multi-line HTML comments (preg_match_all)

    - by Ben
    I have an html document with multiple commented-out PHP arrays, e.g.: <!-- Array ( [key] => 0 ) --> Using PHP, I need to somehow parse the HTML for only these comments (there are other comments that will need to be ignored) and extract the contents. I've been trying to use preg_match_all but my regex skills aren't up to much. Could anyone point me in the right direction? Any help is much appreciated!

  • Method interception in PHP 5.*

    - by Rolf
    Hi everybody, I'm implementing a Log system for PHP, and I'm a bit stuck. All the configuration is defined in an XML file, that declares every method to be logged. XML is well parsed and converted into a multidimensionnal array (classname = array of methods). So far, so good. Let's take a simple example: #A.php class A { public function foo($bar) { echo ' // Hello there !'; } public function bar($foo) { echo " $ù$ùmezf$z !"; } } #B.php class B { public function far($boo) { echo $boo; } } Now, let's say I've this configuration file: <interceptor> <methods class="__CLASS_DIR__A.php"> <method name="foo"> <log-level>INFO</log-level> <log-message>Transaction init</log-message> </method> </methods> <methods class="__CLASS_DIR__B.php"> <method name="far"> <log-level>DEBUG</log-level> <log-message>Useless</log-message> </method> </methods> </interceptor> The thing I'd like AT RUNTIME ONLY (once the XML parser has done his job) is: #Logger.php (its definitely NOT a final version) -- generated by the XML parser class Logger { public function __call($name,$args) { $log_level = args[0]; $args = array_slice($args,1); switch($method_name) { case 'foo': case 'far': //case ..... //write in log files break; } //THEN, RELAY THE CALL TO THE INITIAL METHOD } } #"dynamic" A.php class A extends Logger { public function foo($log_level, $bar) { echo ' // Hello there !'; } public function bar($foo) { echo " $ù$ùmezf$z !"; } } #"dynamic" B.php class B extends Logger { public function far($log_level, $boo) { echo $boo; } } The big challenge here is to transform A and B into their "dynamic" versions, once the XML parser has completed its job. The ideal would be to achieve that without modifying the code of A and B at all (I mean, in the files) - or at least find a way to come back to their original versions once the program is finished. To be clear, I wanna find the most proper way to intercept method calls in PHP. What are your ideas about it ??? Thanks in advance, Rolf

  • Specifying Cell Format in CSV File

    - by Someone
    I am generating a csv file from a PHP array. It opens just fine in Excel and OpenOffice Calc, however the data in one of the column are zip codes. Excel makes the cell formats of the column number general by default. This results in the leading 0 getting dropped in zip codes. Is there any way I can specify the cell formats within the CSV file?
