  • Ext JS 4.2.1 loading controller - best practice

    - by Hown_
    I am currently developing a Ext JS application with many views/controlers/... I am wondering myself what the best practice is for loading the JS controllers/views/and so on... currently i have my application defined like this: // enable javascript cache for debugging, otherwise Chrome breakpoints are lost Ext.Loader.setConfig({ disableCaching: false }); Ext.require('Ext.util.History'); Ext.require('app.Sitemap'); Ext.require('app.Error'); Ext.define('app.Application', { name: 'app', extend: 'Ext.app.Application', views: [ // TODO: add views here 'app.view.Viewport', 'app.view.BaseMain', 'app.view.Main', 'app.view.ApplicationHeader', //administration 'app.view.administration.User' ... ], controllers: [ 'app.controller.Viewport', 'app.controller.Main', 'app.controller.ApplicationHeader', //administration 'app.controller.administration.User', ... ], stores: [ // stores in there.. ] }); somehow this forces the client to load all my views and controllers at startup and is calling all init methods of all controllers of course.. i need to load data everytime i chnage my view.. and now i cant load it in my controllers init function. I would have to do something like this i assume: init: function () { this.control({ '#administration_User': { afterrender: this.onAfterRender } }); }, Is there a better way to do this? Or just an other event? Though the main thing i am questioning myself is if it is the best practice to load all the javascript at startup. Wouldnt it be better to only load the controllers/views/... which the client does need right now? Or should i load all the JS at startup? If i do want to load the controllers dynamicly how could i do this? I assume a would have to remove them from my application arrays (views, controllers, stores) and create an instance if i do need it and mby set the view in the controllers init?! What's best practice??

  • jQuery issue with anchor tag using jqTransform

    - by James Helms
    I'm using jqtransform on my site. When the user is on a for them to be able to use hot keys to move through the selections. I added this function: $wrapper.find('a').keydown(function (e) { var Esc = 27; var code = (e.keyCode ? e.keyCode : e.which); if(code== Esc || (code>=65 &&code<=90)){ var letter = String.fromCharCode(code); if (code==Esc) keyCodes = ""; else{ if (keyCodes=='') keyCodes += letter; else keyCodes += letter.toLowerCase(); var item = $wrapper.find('a[text^=\'' + keyCodes + '\']:first'); item.click(); } } }); inside of $.fn.jqTransSelect. This code works fine in all browsers but IE. the only thing i can find is that IE doesn't like the click event. Can anyone please help me with this? If i debug into the code I can see that item is a select not an anchor like i would expect it to be, and that confuses me even more.

  • Ordering by formula fields in NHibernate

    - by Darin Dimitrov
    Suppose that I have the following mapping with a formula property: <class name="Planet" table="planets"> <id name="Id" column="id"> <generator class="native" /> </id> <!-- somefunc() is a native SQL function --> <property name="Distance" formula="somefunc()" /> </class> I would like to get all planets and order them by the Distance calculated property: var planets = session .CreateCriteria<Planet>() .AddOrder(Order.Asc("Distance")) .List<Planet>(); This is translated to the following query: SELECT Id as id0, somefunc() as formula0 FROM planets ORDER BY somefunc() Desired query: SELECT Id as id0, somefunc() as formula0 FROM planets ORDER BY formula0 If I set a projection with an alias it works fine: var planets = session .CreateCriteria<Planet>() .SetProjection(Projections.Alias(Projections.Property("Distance"), "dist")) .AddOrder(Order.Asc("dist")) .List<Planet>(); SQL: SELECT somefunc() as formula0 FROM planets ORDER BY formula0 but it populates only the Distance property in the result and I really like to avoid projecting manually over all the other properties of my object (there could be many other properties). Is this achievable with NHibernate? As a bonus I would like to pass parameters to the native somefunc() SQL function. Anything producing the desired SQL is acceptable (replacing the formula field with subselects, etc...), the important thing is to have the calculated Distance property in the resulting object and order by this distance inside SQL.

  • Flex NetConnection error: Property onDirtyList not found on flash.net.NetConnection

    - by David Wolever
    I'm having some trouble with NetConnection. The following code makes a connection without issue… var n:NetConnection = new NetConnection(); n.objectEncoding = ObjectEncoding.AMF0; n.addEventListener(NetStatusEvent.NET_STATUS, function(...args):void { trace("HERE"); }); n.connect("rtmp://...host...", ...args); But as soon as the NET_STATUS event handler finishes (ie, hitting "step into" with the debugger), I get this error: ReferenceError: Error #1069: Property onDirtyList not found on flash.net.NetConnection and there is no default value. Error #2044: Unhandled AsyncErrorEvent:. text=Error #2095: flash.net.NetConnection was unable to invoke callback onDirtyList. error=ReferenceError: Error #1069: Property onDirtyList not found on flash.net.NetConnection and there is no default value. at Test/___Test_Application1_creationComplete()[/Users/wolever/Workspace/Test/src/Test.mxml:13] at flash.events::EventDispatcher/dispatchEventFunction() at flash.events::EventDispatcher/dispatchEvent() at mx.core::UIComponent/dispatchEvent()[C:\autobuild\3.5.0\frameworks\projects\framework\src\mx\core\UIComponent.as:9440] at mx.core::UIComponent/set initialized()[C:\autobuild\3.5.0\frameworks\projects\framework\src\mx\core\UIComponent.as:1168] at mx.managers::LayoutManager/doPhasedInstantiation()[C:\autobuild\3.5.0\frameworks\projects\framework\src\mx\managers\LayoutManager.as:718] at Function/http://adobe.com/AS3/2006/builtin::apply() at mx.core::UIComponent/callLaterDispatcher2()[C:\autobuild\3.5.0\frameworks\projects\framework\src\mx\core\UIComponent.as:8744] at mx.core::UIComponent/callLaterDispatcher()[C:\autobuild\3.5.0\frameworks\projects\framework\src\mx\core\UIComponent.as:8684] Which is kind of scary because onDirtyList only yields two hits on Google.

  • How to post to a request using node.js

    - by Mr JSON
    I am trying to post some json to a URL. I saw various other questions about this on stackoverflow but none of them seemed to be clear or work. This is how far I got, I modified the example on the api docs: var http = require('http'); var google = http.createClient(80, 'server'); var request = google.request('POST', '/get_stuff', {'host': 'sever', 'content-type': 'application/json'}); request.write(JSON.stringify(some_json),encoding='utf8'); //possibly need to escape as well? request.end(); request.on('response', function (response) { console.log('STATUS: ' + response.statusCode); console.log('HEADERS: ' + JSON.stringify(response.headers)); response.setEncoding('utf8'); response.on('data', function (chunk) { console.log('BODY: ' + chunk); }); }); When I post this to the server I get an error telling me that it's not of the json format or that it's not utf8, which they should be. I tried to pull the request url but it is null. I am just starting with nodejs so please be nice.

  • jQuery .trigger() or $(window) not working in Google Chrome

    - by Jonathan
    I have this jQuery ajax navigation tabs plugin that I created using some help from CSS-Tricks.com and the jQuery hashchange event plugin (detects hash changes in browsers that don't support it). The code is little long to post it here but it goes something like this: Part 1) When a tab is clicked, it gets the href attribute of that tab and add it to the browsers navigation bar like '#tab_name': window.location.hash = $(this).attr("href"); Part 2) When the navigation bar changes (hash change), it gets the href change like this: window.location.hash.substring(1); (substring is to get only 'tab_name' without the '#'), and then call the ajax function to get the info to display. I want to automatically trigger the plugin to load the first tab when the page is accessed, so at the start of the code I put: if (window.location.hash === '') { // If no '#' is in the browser navigation bar window.location.hash = '#tab_1'; // Add #tab_1 to the navigation bar $(window).trigger('hashchange'); // Trigger a hashchange so 'Part 2' of the plugin calls the ajax function using the '#tab_1' added } The probles is that it works in FF but not in Chrome, I mean, everything works but it seems like the $(window).trigger('hashchange'); is not working because it doesnt get the first tab.. Any suggestions??

  • Save result of for loop in a vector

    - by hendrik
    i think I'm just too tired to see the mistake. i wrote a function to get the maximal value for two data sets from a for loop plot_zu <- function(x) {for (i in 1:x){ z=data_raw[grep(a[i], data_raw$Gene.names),] b=data_raw_ace[grep(a[i], data_raw_ace$Gene.names),] p<-vector("numeric", length(1:length(a))) p[i]<-max(z$t_test_diff) return(p)} } so picture: a is a vector of names and the data set (data_raw(_ace)) are filtered by it. In the end i would like to have all maxima values of column t_test_diff in a vector. After that i want to add the t_test_diff column values from data_raw_ace also. So the problem is, that i get this: [1] 1.210213 0.000000 0.000000 0.000000 0.000000 0.000000 0.000000 [8] 0.000000 0.000000 So there is a problem with brackets or something but i cannot see it ( first value fits). Sorry for no good example but i think it is understandable and an easy to solve question. If im to dumb to explain my problem right, i will add an example. !! Thx a lot !! grateful Hendrik

  • How To Share Information Between Django and Javascript?

    - by Randy
    So I am pretty new to both Django and Javascript (I am using JQuery) and I am wondering if I am doing a hack or if there are more slick ways to send client-side displayed database ids to the django server-side. Here is my process: I have a dataTable (http://datatables.net) that I am displaying rows of data by using the bProcessing option to use AJAX to retrieve records from the database. The URL in my urls.py is something like: url(r'^assets/activitylog/(?P<cid>.*)$', views.getActivityTable_ajax, name="activitylog_table"), and my dataTable ajax-relavant code is something like: "sAjaxSource": "/assets/activitylog/" + getIDFromHTML(), where the javascript function getIDFromHTML() grabs <cid> that is used by the Django view is simply: function getIDFromHTML(){ // Simply return the text in the #release_id div element from the HTML return $("#release_id").html(); }; This is the part that seems "hacky" to me. I am inserting into my template code the database id that I am using in the datatables URL (with display:none in the css) just so I can pass it back to the view. Most of this is necessitated because one cannot use django template tags in the javascript code unless the code is embedded into the HTML itself, which I am not (and will not) do. The only other thing that I have found is to change the URL to get rid of the parameter passed in to: url(r'^assets/activitylog', views.getActivityTable_ajax, name="activitylog_table"), and change the view code to: def getActivityTable_ajax(request): """Returns the activity for a given pid from HTTP GET ajax reqest""" pid = int(urlparse.urlparse(request.META['HTTP_REFERER']).path.split('/')[-1]) # rest of view code here... since the id that I need is on the end of this referer url. This way I don't have to monkey around with embedding the hidden database id into the HTML and passing it back to via ajax the the table population view code. Is it okay to use HTTP_REFERER in the request object in this manner? Am I going about this in the totally wrong way? Thanks in advance!

  • problem with fork()

    - by john
    I'm writing a shell which forks, with the parent reading the input and the child process parsing and executing it with execvp. pseudocode of main method: do{ pid = fork(); print pid; if (p<0) { error; exit; } if (p>0) { wait for child to finish; read input; } else { call function to parse input; exit; } }while condition return; what happens is that i never seem to enter the child process (pid printed is always positive, i never enter the else). however, if i don't call the parse function and just have else exit, i do correctly enter parent and child alternatingly. full code: int main(int argc, char *argv[]){ char input[500]; pid_t p; int firstrun = 1; do{ p = fork(); printf("PID: %d", p); if (p < 0) {printf("Error forking"); exit(-1);} if (p > 0){ wait(NULL); firstrun = 0; printf("\n> "); bzero(input, 500); fflush(stdout); read(0, input, 499); input[strlen(input)-1] = '\0'; } else exit(0); else { if (parse(input) != 0 && firstrun != 1) { printf("Error parsing"); exit(-1); } exit(0); } }while(strcmp(input, "exit") != 0); return 0; }

  • I want to request JSON inside of a WordPress page.

    - by gnucom
    Hello Everyone, For the last few hours I've been trying to set up this http://code.google.com/apis/books/docs/dynamic-links.html on a WordPress blog. Google's API sends back a JSON response (which is supposed to be "put" into _GBSBookInfo variable). However, that variable never is assigned so my javascript callback function explodes saying the variable doesn't exist. So far, all of my javascript is in the WordPress header. I tried this outside of WordPress and it works fine. This is the static page: <script src="http://books.google.com/books?bibkeys=0307346609&jscmd=viewapi&callback=response_handler"> This is the handler: function response_handler(data) { var bookInfo = _GBSBookInfo["0307346609"]; // the var that doesn't exist document.getElementById("test123").innerHTML = bookInfo.thumbnail_url; } Thanks for any help in advance, WordPress has been extremely frustrating by limiting so much! If I'm doing anything stupid please say so, I'm a new javascript programmer. EDIT: I've used firebug so far to identify the problem to be: the _GBSBookInfo variable never gets "created" or "exists". I'm not sure how javascript works at this level. Hopefully this helps. ERRORS: Error: _GBSBookInfo is not defined Line: 79

  • Jquery resizing image

    - by michele
    I'd like to start a discussion about the image resizing using jQuery. That's my contribution: But I think I'm far away from the solution. What about the cropping? Who can help me? $(document).ready(function() { $('.story-small img').each(function() { var maxWidth = 100; // Max width for the image var maxHeight = 100; // Max height for the image var ratio = 0; // Used for aspect ratio var width = $(this).width(); // Current image width var height = $(this).height(); // Current image height // Check if the current width is larger than the max if(width > maxWidth){ ratio = maxWidth / width; // get ratio for scaling image $(this).css("width", maxWidth); // Set new width $(this).css("height", height * ratio); // Scale height based on ratio height = height * ratio; // Reset height to match scaled image } // Check if current height is larger than max if(height > maxHeight){ ratio = maxHeight / height; // get ratio for scaling image $(this).css("height", maxHeight); // Set new height $(this).css("width", width * ratio); // Scale width based on ratio width = width * ratio; // Reset width to match scaled image } }); });

  • Javascript: Onload if checkbox is checked, change li class

    - by BoDiE2003
    I have this code on javascript side: function changeSelectionStyle(id) { if(document.getElementById(id).className != 'yes'){ document.getElementById(id).className = 'yes'; } else{document.getElementById(id).className = '';} } And this on html: <ul> <li id="selectedAuthorities-4_1li" class=""> <input type="checkbox" id="selectedAuthorities-4_1" name="selectedAuthorities" value="ROLE_ADD_COMMENT_TO_CV" checked="checked" onload="changeSelectionStyle(this.id + 'li');" onclick="changeSelectionStyle(this.id + 'li'); checkFatherSelection(this.id);"> <a href="#" onclick="document.getElementById('selectedAuthorities-4_1').click(); return false;"> Agregar comentario <samp><b></b>Permite agregar comentario en el detalle.</samp> </a> </li> Well what I cant get work is when the checkbox is selected, on load, the JS should check it, and assign class="yes" to the li, here: <li id="selectedAuthorities-4_1li" class=""> What should I add to my original JS function to make that possible. Note that li ids are not static, they are dynamic, the html li id is generated.

  • Do COM Dll References Require Manual Disposal? If so, How?

    - by Drew
    I have written some code in VB that verifies that a particular port in the Windows Firewall is open, and opens one otherwise. The code uses references to three COM DLLs. I wrote a WindowsFirewall class, which Imports the primary namespace defined by the DLLs. Within members of the WindowsFirewall class I construct some of the types defined by the DLLs referenced. The following code isn't the entire class, but demonstrates what I am doing. Imports NetFwTypeLib Public Class WindowsFirewall Public Shared Function IsFirewallEnabled as Boolean Dim icfMgr As INetFwMgr icfMgr = CType(System.Activator.CreateInstance(Type.GetTypeFromProgID("HNetCfg.FwMgr")), INetFwMgr) Dim profile As INetFwProfile profile = icfMgr.LocalPolicy.CurrentProfile Dim fIsFirewallEnabled as Boolean fIsFirewallEnabled = profile.FirewallEnabled return fIsFirewallEnabled End Function End Class I do not reference COM DLLs very often. I have read that unmanaged code may not be cleaned up by the garbage collector and I would like to know how to make sure that I have not introduced any memory leaks. Please tell me (a) if I have introduced a memory leak, and (b) how I may clean it up. (My theory is that the icfMgr and profile objects do allocate memory that remains unreleased until after the application closes. I am hopeful that setting their references equal to nothing will mark them for garbage collection, since I can find no other way to dispose of them. Neither one implements IDisposable, and neither contains a Finalize method. I suspect they may not even be relevant here, and that both of those methods of releasing memory only apply to .Net types.)

  • MySql Query lag time?

    - by Click Upvote
    When there are multiple PHP scripts running in parallel, each making an UPDATE query to the same record in the same table repeatedly, is it possible for there to be a 'lag time' before the table is updated with each query? I have basically 5-6 instances of a PHP script running in parallel, having been launched via cron. Each script gets all the records in the items table, and then loops through them and processes them. However, to avoid processing the same item more than once, I store the id of the last item being processed in a seperate table. So this is how my code works: function getCurrentItem() { $sql = "SELECT currentItemId from settings"; $result = $this->db->query($sql); return $result->get('currentItemId'); } function setCurrentItem($id) { $sql = "UPDATE settings SET currentItemId='$id'"; $this->db->query($sql); } $currentItem = $this->getCurrentItem(); $sql = "SELECT * FROM items WHERE status='pending' AND id > $currentItem'"; $result = $this->db->query($sql); $items = $result->getAll(); foreach ($items as $i) { //Check if $i has been processed by a different instance of the script, and if so, //leave it untouched. if ($this->getCurrentItem() > $i->id) continue; $this->setCurrentItem($i->id); // Process the item here } But despite of all the precautions, most items are being processed more than once. Which makes me think that there is some lag time between the update queries being run by the PHP script, and when the database actually updates the record. Is it true? And if so, what other mechanism should I use to ensure that the PHP scripts always get only the latest currentItemId even when there are multiple scripts running in parrallel? Would using a text file instead of the db help?

  • How do you detect when the Flowplayer has started playing the video?

    - by Alex
    Hi. I'm using the Flowplayer Flash video player to play MP4 videos inside an AnythingSlider. I need to detect when the user has clicked the start button on the video so to stop the slideshow and allow the user to view the video. I've tried using this code just to get an alert box but it doesn't do anything (the code is at the end of the page, before the closing </body> tag): <script type="text/javascript"> $f("player","global/js/flowplayer/flowplayer-3.1.5.swf",{ onStart: function(clip) { alert('player started'); } }); </script> The Flowplayer is implemented as part of the html5media library, which automatically detects whether the browser can handle the <video> tag; if not, it replaces the anchor tag below with the Flowplayer: <video id="vid" width="372" height="209" poster="global/vid/bbq-poster.jpg" controls preload> <source id="videoSource" src="global/vid/BBQ_Festival.mp4" type='video/mp4; codecs="avc1.42E01E, mp4a.40.2"' onerror="fallback(this.parentNode)" ></source> <a href="global/vid/BBQ_Festival.mp4" style="display:block;width:372px;height:209px; padding-left:5px; " id="player"> </a> </video> So the $f() function call is in a JavaScript block at the end of the page, to give the player a chance to load correctly. What am I doing wrong? Thanks.

  • asp.net mvc ajax helper/post additional data w/o jquery.

    - by Jopache
    I would like to use the ajax helper to create ajax requests that send additional, dynamic data with the post (for example, get the last element with class = blogCommentDateTime and send the value of that last one to the controller which will return only blog comments after it). I have successfully done so with the help of jQuery Form plugin like so: $(document).ready(function () { $("#addCommentForm").submit(function () { var lastCommentDate = $(".CommentDateHidden:last").val(); var lastCommentData = { lastCommentDateTicks: lastCommentDate }; var formSubmitParams = { data: lastCommentData, success: AddCommentResponseHandler } $("#addCommentForm").ajaxSubmit(formSubmitParams); return false; }); This form was created with html.beginform() method. I am wondering if there is an easy way to do this using the ajax.beginform() helper? When I try to use the same code but replace html.beginform() with ajax.beginform(), when i try to submit the form, I am issuing 2 posts (which is understandable, one being taken care of by the helper, the other one by me with the JS above. I can't create 2 requests, so this option is out) I tried getting rid of the return false and changing ajaxSubmit() to ajaxForm() so that it would only "prepare" the form, and this leads in only one post, but it does not include the extra parameter that I defined, so this is worthless as well. I then tried keeping the ajaxForm() but calling that whenever the submit button on the form gets clicked rather than when the form gets submitted (I guess this is almost the same thing) and that results in 2 posts also. The biggest reason I am asking this question is that I have run in to some issues with the javascript above and using mvc validation provided by the mvc framework (which i will set up another question for) and would like to know this so I can dive further in to my validation issue.

  • DSP - Filter sweep effect

    - by Trap
    I'm implementing a 'filter sweep' effect (I don't know if it's called like that). What I do is basically create a low-pass filter and make it 'move' along a certain frequency range. To calculate the filter cut-off frequency at a given moment I use a user-provided linear function, which yields values between 0 and 1. My first attempt was to directly map the values returned by the linear function to the range of frequencies, as in cf = freqRange * lf(x). Although it worked ok it looked as if the sweep ran much faster when moving through low frequencies and then slowed down during its way to the high frequency zone. I'm not sure why is this but I guess it's something to do with human hearing perceiving changes in frequency in a non-linear manner. My next attempt was to move the filter's cut-off frequency in a logarithmic way. It works much better now but I still feel that the filter doesn't move at a constant perceived speed through the range of frequencies. How should I divide the frequency space to obtain a constant perceived sweep speed? Thanks in advance.

    Hi! I've problem regarding GUI with one Menu and one Order Class. I've created a variable to store how many items have been selected in the Menu Class. private int totalSelected; The var totalSelected is live updated. It can be changed anytime depending on actionPerformed() function.(Exp: totalSelected will add up all the selected items) In the Order Class, how can I access to the live update variable totalSelected in order to retrieve the live update value? When I invoke getTotalSelected() function inside the Menu Class, I will only obtain a 0 value. Thanks for your help ^^! Please allow me to specify my question clearer. public class MenuTab extends JPanel { private JLabel display; private int totalSelected; public MenuTab() { .... } } public getTotalSelected(){ return totalSelected; } private class SelectedListener implements ActionListener { public void actionPerformed() { ....... //Assume that totalSelected has been updated! display = new JLabel("Total: " + totalSelected); // OK to display totalSelected live value here. } } // A new class is the confirmation of order public class OrderConfirmedTab extends JPanel{ private JLabel displayTotal; private MenuTab order = new MenuTab(); public OrderConfirmedTab() { ...... int totalSelected = order.getTotalSelected(); displayTotal = new JLabel("Total: " + totalSelected); // Problem to display totalSelected live value here. // Will obtain 0; // How can I obtain the live updated value from class MenuTab?

The script I have so far is: class Tests(): def function: result function.......... def errorHandle(self): return self.error def sudsPass(self): try: result = self.client.service.GetStreamUri(self.stream, self.token) except suds.WebFault, e: assert False except Exception, e: pass finally: if 'result' in locals(): self.error = True self.errorHandle() assert True else: self.error = False self.errorHandle() assert False def sudsFail(self): try: result = self.client.service.GetStreamUri(self.stream, self.token) except suds.WebFault, e: assert False except Exception, e: pass finally: if 'result' in locals() or self.error == False: assert False else: assert True class GetStreamUri(TestGetStreamUri): def runTest(self): self.sudsPass() class GetStreamUriProtocolFail(TestGetStreamUri): def runTest(self): self.stream.Transport.Protocol = "NoValue" self.errorHandle() self.sudsFail() if __name__ == '__main__': unittest.main() I am trying to get self.error to be set to False if the first test fail. I understand that it is being set in another test but I was hoping someone could help me find a solution to this problem using some other means. Thanks PS. Please ignore the strange tests. There is a problem with the error handling at the moment.

  • Substrings, timer and LED lights, as3

    - by VideoDnd
    How would I sync my timer with my LED lights? I don't understand how to to set up the strings and conditions, so that they are unique to each number space. Need a condition and values for each blinker var condition:Number = 5; if(condition==5){ blink.visible = !blink.visible; //blink_.visible = !box.visible; //blink__.visible = !box.visible; } } Complete code //MY TIMER var timer:Timer = new Timer(100); //INTEGER VALUES var count:int = 0; var fcount:int = 0; var oldcount:int = 0; //FORMATTING STRING function formatCount(i:int):String { var fraction:int = i % 100; var whole:int = i / 100; return ("00" + whole).substr(-2, 2) + "." + (fraction < 10 ? "0" + fraction : fraction); } //START TIMER timer.start(); timer.addEventListener(TimerEvent.TIMER, condition); //ANIMATION function condition(event:TimerEvent):void{ count++; fcount=int(count) var toText:String = formatCount(fcount); dec.text = toText.substr(4, 1); decimal.text = toText.substr(3, 1); ones.text = toText.substr(1, 1); //LED LIGHTS var condition:Number = 5; if(condition==5){ blink.visible = !blink.visible; //blink_.visible = !box.visible; //blink__.visible = !box.visible; } }

  • Why can't I extract a C++ type from a Python type using boost::python::extractor?

    - by Robin
    I've wrapped a C++ class using Py++ and everything is working great in Python. I can instantiate the c++ class, call methods, etc. I'm now trying to embed some Python into a C++ application. This is also working fine for the most-part. I can call functions on a Python module, get return values, etc. The python code I'm calling returns one of the classes that I wrapped: import _myextension as myext def run_script(arg): my_cpp_class = myext.MyClass() return my_cpp_class I'm calling this function from C++ like this: // ... excluding error checking, ref counting, etc. for brevity ... PyObject *pModule, *pFunc, *pArgs, *pReturnValue; Py_Initialize(); pModule = PyImport_Import(PyString_FromString("cpp_interface")); pFunc = PyObject_GetAttrString(pModule, "run_script"); pArgs = PyTuple_New(1); PyTuple_SetItem(pArgs, 0, PyString_FromString("an arg")); pReturnValue = PyObject_CallObject(pFunc, pArgs); bp::extract< MyClass& > extractor(pReturnValue); // PROBLEM IS HERE if (extractor.check()) { // This check is always false MyClass& cls = extractor(); } The problem is the extractor never actually extracts/converts the PyObject* to MyClass (i.e. extractor.check() is always false). According to the docs this is the correct way to extract a wrapped C++ class. I've tried returning basic data types (ints/floats/dicts) from the Python function and all of them are extracted properly. Is there something I'm missing? Is there another way to get the data and cast to MyClass?

  • How to bind to another event after ajax call in jquery

    - by robert
    Hi, I'm creating a graph using flot javascript library. I have enabled clickable event and the div is binded to plotclick event. So, when a datapoint is clicked, an ajax call is made and the result is used to replace the current div. After this i need to bind the div to a new event. I tried to call bind, but it is still bound to old callback. When i call unbind and bind, the new callback is not called. var handleTeacherClick = function( event, pos, item ) { if( typeof item != "undefined" && item ) { var user_id = jQuery( 'input[name="id' + item.datapoint[0] + '"]' ).val(); jQuery.ajax({ type: 'POST', url: BASEPATH + 'index.php/ajax/home/latest', data: { "user_id": user_id }, dataType: 'json', success: function ( result ) { jQuery.plot(jQuery('#stats_prog'), result.progress_data, result.progress_options); jQuery.plot(jQuery('#stats_perf'), result.performance_data, result.performance_options); jQuery('.stats_title'). html('<span class="stats_title">'+ ' >> Chapter '+Math.ceil(item.datapoint[0])+'</span>'); jQuery('#stats_prog')./*unbind("plotclick").*/ bind('plotclick', statClickHandler ); jQuery('#stats_perf')./*unbind("plotclick"). */ bind( 'plotclick', statClickHandler ); }, }); } }

  • Add class active when clicking the menu link with Jquery

    - by Adrian
    I have HTML <div id="top" class="shadow"> <ul class="gprc"> <li><a href="http://www.domain.com/">Home</a></li> <li><a href="http://www.domain.com/link1/">Text1</a></li> <li><a href="http://www.domain.com/link2/">Text2</a></li> <li><a href="http://www.domain.com/link3/">Text3</a></li> <li><a href="http://www.domain.com/link4">Text4</a></li> </ul> </div> and JQUERY $(function () { var url = window.location.pathname, urlRegExp = new RegExp(url.replace(/\/$/, '') + "$"); $('#top a').each(function () { if (urlRegExp.test(this.href.replace(/\/$/, ''))) { $(this).addClass('active'); } }); }); The problem is that when i click on the Home link all tabs are getting active class and don't understand why. I need it for the first link to not get any active class.
