  • How to access SVG elements with Javascript

    - by gargantaun
    I'm messing around with SVG and I was hoping I could create SVG files in Illustrator and access elements with Javascript. Here's the SVG file Illustrator kicks out (It also seems to add a load of junk to the beginning of the file that I've removed) <?xml version="1.0" encoding="utf-8"?> <!DOCTYPE svg PUBLIC "-//W3C//DTD SVG 1.1//EN" "http://www.w3.org/Graphics/SVG/1.1/DTD/svg11.dtd"> <svg version="1.1" id="Layer_1" xmlns="http://www.w3.org/2000/svg" xmlns:xlink="http://www.w3.org/1999/xlink" x="0px" y="0px" width="276.843px" height="233.242px" viewBox="0 0 276.843 233.242" enable-background="new 0 0 276.843 233.242" xml:space="preserve"> <path id="delta" fill="#231F20" d="M34.074,86.094L0,185.354l44.444,38.519l80.741-0.74l29.63-25.186l-26.667-37.037 c0,0-34.815-5.926-37.778-6.667s-13.333-28.889-13.333-28.889l7.407-18.519l31.111-2.963l5.926-21.481l-12.593-38.519l-43.704-5.185 L34.074,86.094z"/> <path id="cargo" fill="#DFB800" d="M68.148,32.761l43.704,4.445l14.815,42.963l-7.407,26.667l-33.333,2.963l-4.444,14.074 l54.074-1.481l22.222,36.296l25.926-3.704l25.926-54.074c0,0-19.259-47.408-21.481-47.408s-31.852-0.741-31.852-0.741 l-19.259-39.259L92.593,8.316L68.148,32.761z"/> <polygon id="beta" fill="#35FF1F" points="86.722,128.316 134.593,124.613 158.296,163.872 190.889,155.724 214.593,100.909 194.593,52.02 227.186,49.057 246.444,92.02 238.297,140.909 216.074,172.761 197.556,188.316 179.778,169.798 164.963,174.983 163.481,197.946 156.815,197.946 134.593,159.428 94.593,151.279 "/> <path class="monkey" id="alpha" fill="#FD00FF" d="M96.315,4.354l42.963,5.185l18.519,42.222l71.852-8.148l20.74,46.667l-5.926,52.593 l-24.444,34.074l-25.185,15.555l-14.074-19.259l-8.889,2.964l-1.481,22.222l-14.074,2.963l-25.186,22.963l-74.074,4.444 l101.481,4.444c0,0,96.297-17.777,109.63-71.852S282.24,53.983,250.389,20.65S96.315,4.354,96.315,4.354z"/> </svg> As you can probably see, each element has an ID, and I was hoping to be able to access individual elements with Javascript so I could change the Fill attribute and respond to events such as click. The HTML is bog basic <!DOCTYPE html> <html> <head> <title>SVG Illustrator Test</title> </head> <body> <object data="alpha.svg" type="image/svg+xml" id="alphasvg" width="100%" height="100%"></object> </body> </html> I guess this is two questions really. a) Is it possible to do it this way, as opposed to using something like Raphael or jQuery SVG. b) If it is possible, what's the technique?

  • Issue with dynamic array Queue data structure with void pointer

    - by Nazgulled
    Hi, Maybe there's no way to solve this the way I'd like it but I don't know everything so I better ask... I've implemented a simple Queue with a dynamic array so the user can initialize with whatever number of items it wants. I'm also trying to use a void pointer as to allow any data type, but that's the problem. Here's my code: typedef void * QueueValue; typedef struct sQueueItem { QueueValue value; } QueueItem; typedef struct sQueue { QueueItem *items; int first; int last; int size; int count; } Queue; void queueInitialize(Queue **queue, size_t size) { *queue = xmalloc(sizeof(Queue)); QueueItem *items = xmalloc(sizeof(QueueItem) * size); (*queue)->items = items; (*queue)->first = 0; (*queue)->last = 0; (*queue)->size = size; (*queue)->count = 0; } Bool queuePush(Queue * const queue, QueueValue value, size_t val_sz) { if(isNull(queue) || isFull(queue)) return FALSE; queue->items[queue->last].value = xmalloc(val_sz); memcpy(queue->items[queue->last].value, value, val_sz); queue->last = (queue->last+1) % queue->size; queue->count += 1; return TRUE; } Bool queuePop(Queue * const queue, QueueValue *value) { if(isEmpty(queue)) return FALSE; *value = queue->items[queue->first].value; free(queue->items[queue->first].value); queue->first = (queue->first+1) % queue->size; queue->count -= 1; return TRUE; } The problem lies on the queuePop function. When I call it, I lose the value because I free it right away. I can't seem to solve this dilemma. I want my library to be generic and modular. The user should not care about allocating and freeing memory, that's the library's job. How can the user still get the value from queuePop and let the library handle all memory allocs/frees?

  • Regex to match partial words (JavaScript)

    - by nw
    I would like to craft a case-insensitive regex (for JavaScript) that matches street names, even if each word has been abbreviated. For example: n univ av should match N University Ave king blv should match Martin Luther King Jr. Blvd ne 9th should match both NE 9th St and 9th St NE Bonus points (JK) for a "replace" regex that wraps the matched text with <b> tags.

  • Javascript data store solution using PhoneGap

    - by nickcartwright
    Hiya, Does anyone have any experience of storing data in JavaScript across all mobile platforms using PhoneGap? My ideal solution would be to use something like SQLite, but unfortunately SQLite isn't supported across all the platforms PhoneGap supports. I tried to ask this question a little while ago, but it got quite a few negative marks. If you think this is a bad / pointless question I would love to know as it will hopefully help me to understand the problem! Cheers, Nick.

  • Problem with first Windows 7 gadget getting javascript to run

    - by norlando02
    For my first windows gadget I'm trying to make one that displays the current time and date. The code below is what I have, but I can't figure out why the javascript is not running. Any ideas? <html> <head> http-equiv="Content-Type" content="text/html; charset=Unicode" /> <title>Clock</title> <style type="text/css"> body { width: 130px; height: 60px; margin: 1 1 1 2; } body { font-family: Segoe UI, Arial; font-size: 11px; font-weight: bold; white-space: nowrap; } </style> <script type="text/javascript"> var background; var interval; var connection_id; var timeZone; var now; function load() { try { interval = 1000; connection_id = 0; timeZone = System.Time.currentTimeZone; update(); } catch(e){} } function update() { try { now = new Date(Date.parse(System.Time.getLocalTime(timeZone))); curDate.innerHTML = now.format('M jS, Y'); curTime.innerHTML = now.format('h:i:s A'); clearTimeout(connection_id); connection_id = setTimeout("update()", interval); } catch(e) {} </script> </head> <body onload="load()"> <div id="curDate"> </div> <div id="curTime"> </div> </body> </html>

  • Fmylife javascript copy-paste into link

    - by davezor
    Fmylife.com has a nifty feature that when you copy the text from a post, it actually copies a LINK (html) so that when you paste it into your email/facebook/instant messenger/twitter/whatever it automatically will link to the post, giving them more traffic and more page views and more ad revenue, etc. I looked into their javascript files but can't seem to find how they do it. How would one go about copying this behavior?

  • javascript - multiple dependent/cascading/chained select boxes on same form

    - by Aaron
    I'm populating select box options via jquery and json but I'm not sure how to address multiple instances of the same chained select boxes within my form. Because the select boxes are only rendered when needed some records will have ten sets of chained select boxes and others will only need one. How does one generate unique selects to support the auto population of secondary select options? Here's the code I'm using, and I thank you in advance for any insight you may provide. <script type="text/javascript" src="jquery.js"></script> <script type="text/javascript"> function populateACD() { $.getJSON('/acd/acd2json.php', {acdSelect:$('#acdSelect').val()}, function(data) { var select = $('#acd2'); var options = select.attr('options'); $('option', select).remove(); $.each(data, function(index, array) { options[options.length] = new Option(array['ACD2']); }); }); } $(document).ready(function() { populateACD(); $('#acdSelect').change(function() { populateACD(); }); }); </script> <?php require_once('connectvars.php'); $dbc = mysqli_connect(DB_HOST, DB_USER, DB_PASSWORD, DB_NAME); $squery = "SELECT ACD1ID, ACD1 from ACD1"; $sdata = mysqli_query($dbc, $squery); // Loop through the array of ACD1s, placing them into an option of a select echo '<select name="acdSelect" id="acdSelect">'; while ($row = mysqli_fetch_array($sdata)) { echo "<option value=" . $row['ACD1ID'] . ">" . $row['ACD1'] . "</option>\n"; } echo '</select><br /><br />'; <select name="acd2" id="acd2"> </select> acd2json.php <?php $dsn = "mysql:host=localhost;dbname=wfn"; $user = "acd"; $pass = "***************"; $pdo = new PDO($dsn, $user, $pass); $rows = array(); if(isset($_GET['acdSelect'])) { $stmt = $pdo->prepare("SELECT ACD2 FROM ACD2 WHERE ACD1ID = ? ORDER BY ACD2"); $stmt->execute(array($_GET['acdSelect'])); $rows = $stmt->fetchAll(PDO::FETCH_ASSOC); } echo json_encode($rows); ?>

  • Get all Javascript Variables?

    - by Matrym
    Is there a way for javascript to detect all assigned variables? For example, if one js file creates a bunch of vars (globally scoped), can a subsequent file get all the vars without knowing what they're named and which might exist? Thanks in advance :)

  • Javascript crazy idea finding a node

    - by Louis
    I had a crazy (but so crazy that it just might work) idea where every element on a page is created in javascript but given an ID which is a hash of its path in the DOM. So instead of searching through the DOM to find an element, you hash the path and then getElementById() with that hash. Problem with this is getting the path might be more expensive than searching the DOM in the first place. Any ideas how this could be done or if it is just plain stupid?

  • Javascript to match a specific number using regular expressions

    - by ren33
    I was using javascript to detect for specific key strokes and while writing the method I thought I'd try regular expressions and the test() method and came up with: if (/8|9|37|38|46|47|48|49|50|51|52|53|54|55|56|57|96|97|98|99|100|101|102|103|104|105|110/.test(num)) { // do something if there's a match } This doesn't seem to work 100% as some values seem to make it past the regex test, such as 83. I've since moved on, but I'm still curious as to why this didn't work.

  • Add a marker to an image in javascript?

    - by Richard
    Hi, Anyone know how I can add a marker to an image (not a map) in Javascript? Ideally I'd like a handler that behaves much like adding a marker to a map - i.e. onclick causes a marker to be displayed at the point that was clicked, and returns the x/y pixel coordinates of the point that was clicked. Is this possible? Cheers Richard

  • Cut and Paste Code Reuse - JavaScript and C#

    - by tyndall
    What is the best tool(s) for tracking down "cut and paste reuse" of code in JavaScript and C#? I've inherited a really big project and the amount of code that is repeated throughout the app is 'epic'. I need some help getting handle on all the stuff that can be refactored to base classes, reusable js libs, etc... If it can plug into Visual Studio 2010, that would be an added bonus.

  • translating Ecmascript (Java,javascript,Actionscript) knowledge to Objective C

    - by eco_bach
    Hi Newcomer to Objective C and trying to translate concepts and sytax I know from ecmascript based languages to Objective C. Is it proper to think of the .h header file in ObjectiveC as an Interface in Actionscript? Lets take the following code example in Objective C which calls a method containing 2 arguments [myTextObject setString: @"Hello World" color: kWhiteColor]; In Actionscript(or javascript) would this be the same as calling 2 accessor methods on 'myTextObject'? ie myTextObject.setString("Hello World") myTextObject.color(kWhiteColor);
