  • MooTools Fx.Slide throwing this.element is null

    - by Brant
    The following code is throwing the error "this.element is null". However, the wid_cont is definitely grabbing an element. window.addEvent('domready',function(){ var min = $(document.body).getElements('a.widget_minimize'); min.addEvent('click', function(event){ event.stop(); //var box = ; var wid_cont = ($(this).getParents('.widget_box').getElement('.widget_box_content_cont')); var myVerticalSlide = new Fx.Slide(wid_cont); myVerticalSlide.slideOut(); } ); }); It's moo tools 1.2.4 and has the fx.slide included....

  • Confusion regarding laziness

    - by Abhinav Kaushik
    I have a function myLength = foldl (\ x _ -> x + 1) 0 which fails with stack overflow with input around 10^6 elements (myLength [1..1000000] fails). I believe that is due to the thunk build up since when I replace foldl with foldl', it works. So far so good. But now I have another function to reverse a list : myReverse = foldl (\ acc x -> x : acc) [] which uses the lazy version foldl (instead of foldl') When I do myLength . myReverse $ [1.1000000]. This time it works fine. I fail to understand why foldl works for the later case and not for former?

  • Python lambda returning None instead of empty string

    - by yoshi
    I have the following lambda function: f = lambda x: x == None and '' or x It should return an empty string if it receives None as the argument, or the argument if it's not None. For example: >>> f(4) 4 >>> f(None) >>> If I call f(None) instead of getting an empty string I get None. I printed the type of what the function returned and I got NoneType. I was expecting string. type('') returns string, so I'd like to know why the lambda doesn't return an empty string when I pass None as an argument. I'm fairly new to lambdas so I might have misunderstood some things about how they work.

  • Difference between 'scope' and 'namespace'?

    - by katriel
    What is the difference, in general, between the concepts of namespaces and scope? To my understanding, both describe the parts of a program in which a variable/object/method/function will be accessible. I understand that 'scope' tends to be a property of the variable (e.g., "This variable has global scope"), while a 'namespace' is a property of the program (e.g., "A Python function creates a local namespace"). Are there other differences? Global scope vs global namespace addresses a slightly narrower question: global namespaces in C++. http://www.alan-g.me.uk/tutor/tutname.htm states, There are a few very subtle differences between the terms but only a Computer Scientist pedant would argue with you, and for our purposes namespace and scope are identical. What are those subtle differences? Under what circumstances or with which kinds of languages do people use each concept?

  • Windows disassembler: looking for a tool...

    - by SigTerm
    Hello. I'm looking for a (preferably free) tool that can produce "proper" disassembly listing from a (non-.NET) windows PE file (*.exe or *.dll). Important requirement: it should be possible to run the listing through a windows assembler (nasm, masm or whatever) and get working exe again (not necessarily identical to original one, but it should behave in the same way). Intended usage is adding new subroutines into existing code, when source is not available. Ideally, tool should be able to detect function/segment boundaries, API calls, and generate proper labels for jumps (I can live without labels for loops/jumps, though, but function boundary detection would be nice), and keep program resources/segments in place. I'm already aware of IdaPRO(not free), OllyDBG (useful for in-place hacking, doesn't generate disassembly listing, AFAIK), ndisasm (output isn't suitable for assembler), dumpbin (useful, but AFAIK, output isn't suitable for assembler) and "proxy dll" technique. Ideas? Or maybe there is a book/tutorial that explains some kind of alternative approach?

  • jquery noConflict not working in IE8 only

  • Google Maps within a dynamically loaded jquery Accordion

    - by marr75
    I'm trying to load a google map within a jquery ui accordion with contents loaded by ajax. $("h2", "#accordion").click(function(e) { var contentDiv = $(this).next("div"); if (contentDiv.children().length == 1) { contentDiv.load($(this).find("a").attr("href")); contentDiv.ready(function(){ var latlng = new google.maps.LatLng(-34.397, 150.644); var myOptions = { zoom: 8, center: latlng, mapTypeId: google.maps.MapTypeId.ROADMAP }; var map = new google.maps.Map(document.getElementById("map_canvas"), myOptions); }) } }); That's my current code (Google Maps API V3), but it redirects to the url of the href when I click currently, obviously with no google map because there's no javascript in this response. If I comment out the map line everything works fine (except the map itself).

  • How can I make Swig correctly wrap a char* buffer that is modified in C as a Java Something-or-other

    - by Ukko
    I am trying to wrap some legacy code for use in Java and I was quite happy to see that Swig was able to handle the header file and it generate a great wrapper that almost works. Now I am looking for the deep magic that will make it really work. In C I have a function that looks like this DLL_IMPORT int DustyVoodoo(char *buff, int len, char *curse); This integer returned by this function is an error code in case it fails. The arguments are buff is a character buffer len is the length of the data in the buffer curse the another character buffer that contains the result of calling DustyVoodoo So, you can see where this is going, the result is actually coming back via the third argument. Also len is confusing since it may be the length of both buffers, they are always allocated as being the same size in calling code but given what DustyVoodoo does I don't think that they need be the same. To be safe both buffers should be the same size in practice, say 512 chars. The C code generated for the binding is as follows: SWIGEXPORT jint JNICALL Java_pemapiJNI_DustyVoodoo(JNIEnv *jenv, jclass jcls, jstring jarg1, jint jarg2, jstring jarg3) { jint jresult = 0 ; char *arg1 = (char *) 0 ; int arg2 ; char *arg3 = (char *) 0 ; int result; (void)jenv; (void)jcls; arg1 = 0; if (jarg1) { arg1 = (char *)(*jenv)->GetStringUTFChars(jenv, jarg1, 0); if (!arg1) return 0; } arg2 = (int)jarg2; arg3 = 0; if (jarg3) { arg3 = (char *)(*jenv)->GetStringUTFChars(jenv, jarg3, 0); if (!arg3) return 0; } result = (int)PemnEncrypt(arg1,arg2,arg3); jresult = (jint)result; if (arg1) (*jenv)->ReleaseStringUTFChars(jenv, jarg1, (const char *)arg1); if (arg3) (*jenv)->ReleaseStringUTFChars(jenv, jarg3, (const char *)arg3); return jresult; } It is correct for what it does; however, it misses the fact that cursed is not just an input, it is altered by the function and should be returned as an output. It also does not know that the java Strings are really buffers and should be backed by a suitably sized array. I think that Swig can do the right thing here, I just can't figure out from the documentation how to tell Swig what it needs to know. Any typemap masers in the house?

  • Code Profiling in the Windows Sidebar Environment

    - by Matt
    Does anyone know of a way I can code-profile my Windows Sidebar Gadget? I've played around with the code-profiling tool in IE8's "Developer Tools" and the code-profiling included in Visual Studio 2010, but I can't find a way to include the System.* API, which my gadget relies on (as it is standard in the Sidebar environment). The gadget also relies on cross-domain AJAX requests; which is normally permitted in the Sidebar environment. By code-profiling I primarily mean: Function call count Function execution time Any ideas would be much appreciated. Regards, Matt

  • Jquery Datepicker not selecting the default date

    - by Chirantan
    I have my datepicker set up like this $("#scheduled_date_163").datepicker({ onSelect: function(dateText, inst) { jQuery.get("/tasks/inplace_edit?id=scheduled_date_163&class_name=Task&value=" + dateText, function(data){ $('#scheduled_date_163').html(data); $('#scheduled_date_163').removeClass('hasDatepicker'); }) } }); $('#scheduled_date_163').datepicker( "option", "defaultDate", $.datepicker.parseDate("d m y", "31 8 2009") ); As you can see the date is hardcoded. It is supposed to be replaced with some code. However, the datepicker refuses to pick the date up! It always shows me the current date. Unable to figure out why. I even tried giving the date in string and +7 etc. But today's date itself is shown as the default date. What could be causing this?

  • jQuery Validation Engine with Mime

    - by Diego Pucci
    I have this custom rule with tje jQuery validation Engine: "validateMIME": { "func": function(field, rules, i, options){ var fileInput = field[0].files[0]; var MimeFilter = new RegExp(rules[3],'i'); if (fileInput) { return MimeFilter.test(fileInput.type); } else { return true;} }, "alertText": "* Estensione non supportata" }, The problem is that this is working ONLY if the field is required. But in my case the field is not required, but if filled then the Mime type needs to be checked. How do I edit this function to work with non required fields? what's wrong with it? Thanks

  • Parsing Serialized JSON DataSet using Jquery

    - by Zachary Carter
    Hello all, and thanks for reading. I wrote a web service which is called through jsonp, and returns a .Net 3.5 DataSet which I then want to parse using jquery. It appears that the getJson() method is working fine as far as parsing the json goes. The following request - $.getJSON("http://localhost:80/ws.asmx/Example?format=json&callback=?", function(data) { alert(data.d); }); results in - {"Tables": [ { "Rows": [ { "CASE_TYP_CD": "M", "CASE_TYP_DESC": "MOVING VIOLATION", "AUTO_GENERATE": "Y", "CONFIDENTIAL_FLG": "N" }, { "CASE_TYP_CD": "T", "CASE_TYP_DESC": "TRUANCY/FAILURE TO ATTEND SCHOOL", "AUTO_GENERATE": "Y", "CONFIDENTIAL_FLG": "N" }, { "CASE_TYP_CD": "J", "CASE_TYP_DESC": "JUVENILE", "AUTO_GENERATE": "Y", "CONFIDENTIAL_FLG": "N" }... Well I'm kind of new at this whole json thing and I can't figure out how to gain access to the values held in the nodes. I was thinking it would be something like - $.each("CASE_TYP_CD", function() { //code goes here }); But that doesn't seem to be working. Could anyone help me out with this? Thanks in advance!

  • referencing a WCF web service

    - by ErnieStings
    Our current project uses an asmx service. We want to keep this service for now, but would like to add an additional wcf service for ajax calls. I followed a procedure i found online to set up the service and it works fine with javascript in aspx files within that particular project but i'm unsure how to reference it in javascript files in a different project (in the same solution). If someone could point me in the right direction it would be much appreciated. Thanks, Shawn EDIT: i wish to make calls in javascript similar to the following: function Button1_onclick() { var service = new AjaxServices.TestService(); service.wcfTest(4, onSuccess, null, null); } function onSuccess(result){ document.getElementById("ajaxPlaceHolder").innerHTML = "<p>" + result + "</p>"; } // ]]> but i'm willing to explore the jQuery option as well.

  • CakePHP Accessing Dynamically Created Tables?

    - by Dave
    As part of a web application users can upload files of data, which generates a new table in a dedicated MySQL database to store the data in. They can then manipulate this data in various ways. The next version of this app is being written in CakePHP, and at the moment I can't figure out how to dynamically assign these tables at runtime. I have the different database config's set up and can create the tables on data upload just fine, but once this is completed I cannot access the new table from the controller as part of the record CRUD actions for the data manipulate. I hoped that it would be along the lines of function controllerAction(){ $this->uses[] = 'newTable'; $data = $this->newTable->find('all'); //use data } But it returns the error Undefined property: ReportsController::$newTable Fatal error: Call to a member function find() on a non-object in /app/controllers/reports_controller.php on line 60 Can anyone help.

  • How to hide Amazon webstore default toolbar with Prototype?

    - by melaos
    Hi Guys, after playing around this morning, i've found that there's this default chunk of html code in the amazon webstore which will add a toolbar on top of the page. the html looks like below: <td id="wba_logo_bg"> <table class="logo" border="0" cellpadding="0" cellspacing="0" width="100%"> <tbody><tr><td align="left"></td> <td class="wba_account" style="padding: 5px;" align="right" valign="top"> <table border="0" cellpadding="0" cellspacing="0"> <form action="#" id="searchForm" method="get" name="searchForm"></form> <tbody><tr><td class="wba_account_link"> <a xmlns:xhtml="http://www.w3.org/1999/xhtml" class="myAccountNav" href="#" onclick="return false;">home</a></td> <td class="myAccountDots"></td> <td class="wba_account_link"><a class="myAccountNav" href="#" onclick="return false;">view cart</a></td> <td class="myAccountDots"></td><td class="wba_account_link"><a class="myAccountNav" href="#" onclick="return false;">my account</a></td> <td class="myAccountDots"></td><td class="wba_account_link"><a class="myAccountNav" href="#" onclick="return false;">order status</a></td> <td><img src="pageEditor_files/1_pixel.gif" hspace="7"></td> <td><input name="keyword" tabindex="1" type="text"></td> <td><img alt="Search" class="wba_search_btn" onclick="return false;" onkeyup="if (13==event.keyCode) searchForm.submit();" src="pageEditor_files/btn_search.gif" style="cursor: pointer;" tabindex="2" title="Search" hspace="3"> </td></tr></tbody> </table> </td></tr></tbody> </table> </td> and thus far i was able to use prototype to find those with the class name of wba_account_link and hide them via the codes below: function hideAmazonToolbar() { $("wba_logo_bg").hide(); }//end function but what i really want to do is preferably to hide the whole tbody instead, but with my limited prototype skills, i don't really know how to do this. can anybody point me to the right resources on how to get this done? thanks! EDIT Went higher up and apparently there's a td with an id, and solve it using prototype hide function! man, i love javascript framework :) thanks :)
