  • Changing iframe visibility on Mozilla not working

    - by Honski
    I've got a simple iframe that I want hidden until an event from that iframe is fire via easyXDM. It's working fine on Chrome, but somehow not on Mozilla. The event is being fired on both browsers, but only shows the iframe on Chrome. The only way to show the iframe on Mozilla is to call the same code using an onclick event. HTML: <a href="#" onclick="shower(); return false;">show frame (always working)</a> <br> <iframe src="testsite.php" width="600" height="424" scrolling="no" border="0" id="my-iframe3" style="visibility: hidden;" onload="scrollIFrame();" name="my-iframe3"> Javascript: function shower() { document.getElementById("my-iframe3").style.visibility="visible"; } var socket = new easyXDM.Socket( { onMessage: function(message, origin) { if (message == "hi") { socket.postMessage("do something"); } else if (message == "ready") { shower(); } } }); Both browsers receive the "ready" message.

  • CURL request incomplete, suspect timeout but not sure.

    - by girlygeek
    I am currently using CURL via a php script running as daily cron to export product data in csv format from a site's admin area. The normal way of exporting data will be to go to the Export page in a browser, and set the configuration, then click on "export data" button. But as the number of products I am exporting is very large, and it takes more than 5-10 mins to export the data, I've decided to use php's curl function to mimic this on a daily basis via cron. Previously, it is working fine, but recently as I increased the number of products in the store by 500+, the script fails to return the exported data. Testing it manually via clicking on the "export" button in a browser, does return the data correctly. Thus there is no "timeout" issue with running the export in a browser manually. I've tested and by removing/decreasing the number of products (thus the time needed), the php-curl script works fine again when run from cron. So I suspect that it has something to do with timeouts issue, specifically with the curl function in php. I've set both CURLOPT_TIMEOUT and CURLOPT_CONNECTTIMEOUT to '0' respectively to try. In the php-curl script, I've also set "set_time_limit(3000)". But still it does not work, and the request will timeout, with the script failing to return with a complete set of csv data. Any help in helping me resolve/understand this issue will be much appreciated!

  • include ::before pseudo class in javascript

    - by user1955837
    Why is this thing not working? If I remove ::before from javascript and css it works. But due to the design needs there has to be a ::before. How do I point to the class + ::before? $(function () { var sections = $("section"); var navigation_links = $("nav a"); sections.waypoint({ handler: function (event, direction) { var active_section; active_section = $(this); if (direction === "up") active_section = active_section.prev(); var active_link = $('nav a[href="#' + active_section.attr("id") + '"]'); navigation_links.removeClass("selected::before"); active_link.addClass("selected::before"); }, offset: '25%' }) }); css: .selected::before { display: block; content: ""; margin-top: 6px; width: 8px; height: 8px; background: url(../img/sprite.png) -126px -196px; background-size: 400px 480px; float: left; margin-left: 20px; margin-right: 20px; }

  • Moving x,y position of all array objects every frame in actionscript 3?

    - by Dylan Gallardo
    I have my code setup so that I have an movieclip in my library a class called "block" being duplicated multiple times and added into an array like this: function makeblock(e:Event){ newblock=new block; newblock.x=10; newblock.y=10; addChild(newblock); myarray[counter] = newblock; //adds a newblock object into array counter += 1; } Then I have a loop with a currently primitive way of handling my problem: stage.addEventListener(Event.ENTER_FRAME, gameloop); function gameloop(evt:Event):void { if (moveright==true){ myarray[0].x += 5; myarray[1].x += 5; myarray[2].x += 5 -(and so on)- My question is how can I change x,y values every frame for new objects duplicated into the array, along with the previous ones that were added. Of course with a more elegant way than writing it out myself... array[0].x += 5, array[1], array[2], array[3] etc. Ideally I would like this to go up to 500 or more array objects for one array so obviously I don't want to be writing it out individually haha, I also need it to be consistent with performance so using a for loop or something to loop through the whole array and move each x += 5 wouldn't work would it? Anyway, if anyone has any ideas that'd be great!

  • Unknown reason for code executing the way it does in python

    - by Jasper
    Hi I am a beginner programmer, using python on Mac. I created a function as a part of a game which receives the player's input for the main character's name. The code is: import time def newGameStep2(): print ' ****************************************** ' print '\nStep2\t\t\t\tCharacter Name' print '\nChoose a name for your character. This cannot\n be changed during the game. Note that there\n are limitations upon the name.' print '\nLimitations:\n\tYou cannot use:\n\tCommander\n\tLieutenant\n\tMajor\n\t\tas these are reserved.\n All unusual capitalisations will be removed.\n There is a two-word-limit on names.' newStep2Choice = raw_input('>>>') newStep2Choice = newStep2Choice.lower() if 'commander' in newStep2Choice or 'lieutenant' in newStep2Choice or 'major' in newStep2Choice: print 'You cannot use the terms \'commander\', \'lieutenant\' or \'major\' in the name. They are reserved.\n' print time.sleep(2) newGameStep2() else: newStep2Choice = newStep2Choice.split(' ') newStep2Choice = [newStep2Choice[0].capitalize(), newStep2Choice[1].capitalize()] newStep2Choice = ' ' .join(newStep2Choice) return newStep2Choice myVar = newGameStep2() print myVar When I was testing, I inputted 'major a', and when it asked me to input another name, i inputted 'a b'. However, when it returned the output of the function, it returns 'major a'. I went through this with a debugger, yet I still can't seem to find where the problem occurred. Thanks for any help, Jasper

  • jQuery Code Only Fires On Hard Refresh?

    - by Rob Vanders
    The XFBML version of the Facebook Registration plugin only loads HTTPS. I need it to load HTTP so my form does not call a security error mismatch between domains. I wrote this code to get the SRC and rewrite it with out HTTPS It works fine on the first load, however on Chrome and Safari it only loads the first time and on HARD refreshes. It does not load on standard reloads or by pressing "enter" on the address bar. Here is the code $(window).load(function () { // Replace HTTPS with HTTP when frame has loaded $(".subscribe iframe").each(function(){ var source = $(this).attr("src"); //alert(source); var sourceNew = source.replace("https", "http"); // change https to http alert(sourceNew); $(this).attr("src", sourceNew); }); }); I have .HTACCESS set to disable server cache <Files *> Header set Cache-Control: "private, pre-check=0, post-check=0, max-age=0" Header set Expires: 0 Header set Pragma: no-cache </Files> What is causing this to not fire reliably? Thanks

  • Generics Java and Shadowing of type parameters

    - by rubixibuc
    This code seems to work fine class Rule<T> { public <T>Rule(T t) { } public <T> void Foo(T t) { } } Does the method type parameter shadow the class type parameter? Also when you create an object does it use the type parameter of the class? example Rule<String> r = new Rule<String>(); Does this normally apply to the type parameter of the class, in the situation where they do not conflict? I mean when only the class has a type parameter, not the constructor, or does this look for a type parameter in the constructor? If they do conflict how does this change? SEE DISCUSSION BELOW if I have a function call x = <Type Parameter>method(); // this is a syntax error even inside the function or class ; I must place a this before it, why is this, and does everything still hold true. Why don't I need to prefix anything for the constructor call. Shouldn't Oracle fix this.

  • Cancel text selection on textinput in Flex

    - by Michael
    So the real problem is the lack of an onReleaseOutside function. I found some examples of how to bypass this during a drag function but it was not applicable for a text input. The problem is that when a user selects some text in textinput and mouses off the application area and then mouses up, I'm getting a problem that the textinput keeps thinking that the mouse down is actively selecting text in the textinput and continually overwrites the characters being entered in the textinput. You can test this at http://palermo.infusedindustries.com [ in the search bar of the live store on the page, type some text, then highlight it all and don't let up on the mouse until you are outside the store. I finally hacked some junk together so I can tell if the mouse goes off the stage using some code like var x = stage.mouseX; var y = stage.mouseY; if(x < 0 || y <0 || x >stage.stageWidth || y > stage.stageHeight) I'd like to just make the textinput stop thinking it should be highlighting text so that even if the user scrolls out of the applet and mouses up that the text input still overwrites what is in the search bar and functions as normal. I can't seem to find any events or ways to tell the Flex text field to stop thinking that the mouse is down and that the user is done selecting text.

  • How to submit to the server with JQuery.UI Dialog and ASP.Net?

    Hi, I'm looking for a way to submit information captured in a JQuery Dialog to the server in ASP.Net.

  • Creating dynamic icons based on data entered into database from django forms

    - by John Hoke
    So I'm using Django to create a projects page with multiple forms for each project. Let's call them form 1, 2, 3, and 4. Once you create a project you can fill out any of these forms. I want to create "buttons" or links for each one of the forms that would show up on the main page. Now this is the part I need help with: Step 1. I want it so that if you click on a button for a form (say form 1) and none exists for that project yet a pop up would come up saying "This form does not exist yet, are you sure you want to create one?". And if you'd answer yes you would be directed to the form page. Step 2. But if that form does exist, I don't want any pop up to open and I want the link to take the user directly to that page. Step 3. My next problem is this. These forms are in order, so if you didn't create form 1 but created form 2, I don't want to give the user access to form 1. So in this scenario, if you click on form 1 I want a pop up to open and say "This form can no longer be created", and the link wouldn't function anymore. Basically the button will have 3 function. First it should look at the database and if data for that specific form exists it should do "Step 2", if data for that form and the proceeding forms don't exist it should do "Step 1", and if data for that form doesn't exist but data for proceeding form's does exist is should do "Step 3". Is this possible? Please help as I need to find a solution to this soon. Any help would be highly appreciated. Thank you

  • Using enum values to represent binary operators (or functions)

    - by Bears will eat you
    I'm looking for an elegant way to use values in a Java enum to represent operations or functions. My guess is, since this is Java, there just isn't going to be a nice way to do it, but here goes anyway. My enum looks something like this: public enum Operator { LT, LTEQ, EQEQ, GT, GTEQ, NEQ; ... } where LT means < (less than), LTEQ means <= (less than or equal to), etc - you get the idea. Now I want to actually use these enum values to apply an operator. I know I could do this just using a whole bunch of if-statements, but that's the ugly, OO way, e.g.: int a = ..., b = ...; Operator foo = ...; // one of the enum values if (foo == Operator.LT) { return a < b; } else if (foo == Operator.LTEQ) { return a <= b; } else if ... // etc What I'd like to be able to do is cut out this structure and use some sort of first-class function or even polymorphism, but I'm not really sure how. Something like: int a = ..., b = ...; Operator foo = ...; return foo.apply(a, b); or even int a = ..., b = ...; Operator foo = ...; return a foo.convertToOperator() b; But as far as I've seen, I don't think it's possible to return an operator or function (at least, not without using some 3rd-party library). Any suggestions?

  • Iphone -- maintaining a list of strings and a corresponding typedef enum

    - by William Jockusch
    Suppose I have the following: typedef enum functionType {ln, sin, sqrt} functionType; NSArray *functions = [NSArray arrayWithObjects: @"ln", @"sin", @"sqrt", nil]; Suppose further that *functions will not change at runtime. Question -- is there any way to set up a single structure which updates both of these? So that I only have to keep track of one list, instead of two. To explain what is going on -- the idea is that string input from the user will be stored in a variable of type functionType. Later on, I will have code like this: double valueOfFunction: (functionType) function withInput: (double) input switch (function) { case ln: return ln(input); case sin: return sin(input); case sqrt: return sqrt(input); //etc . . . could grow to include a lot of functions. } And valueOfFunction needs to be fast. So I don't want to be doing string comparisons there.

  • Performance difference between functions and pattern matching in Mathematica

    - by Samsdram
    So Mathematica is different from other dialects of lisp because it blurs the lines between functions and macros. In Mathematica if a user wanted to write a mathematical function they would likely use pattern matching like f[x_]:= x*x instead of f=Function[{x},x*x] though both would return the same result when called with f[x]. My understanding is that the first approach is something equivalent to a lisp macro and in my experience is favored because of the more concise syntax. So I have two questions, is there a performance difference between executing functions versus the pattern matching/macro approach? Though part of me wouldn't be surprised if functions were actually transformed into some version of macros to allow features like Listable to be implemented. The reason I care about this question is because of the recent set of questions (1) (2) about trying to catch Mathematica errors in large programs. If most of the computations were defined in terms of Functions, it seems to me that keeping track of the order of evaluation and where the error originated would be easier than trying to catch the error after the input has been rewritten by the successive application of macros/patterns.

  • How can I [simply] consume JSON Data in a Line of Business Web Application

    - by Atomiton
    I usually use JSON with jQuery to just return a string with html. However, I want to start to use Javascript objects in my code. What's the simplest way to get started using json objects on my page? Here's a sample Ajax call ( after $(document).ready( { ... }) of course: $('#btn').click(function(event) { event.preventDefault(); var out = $('#result'); $.ajax({ url: "CustomerServices.asmx/GetCustomersByInvoiceCount", success: function(msg) { // // Iterate through the json results and spit them out to a page? // }, data: "{ 'invoiceCount' : 100 }" }); }); My WebMethod: [WebMethod(Description="Gets customers with more than n invoices")] public List<Customer> GetCustomersByInvoiceCount(int? invoiceCount) { using (dbDataContext db = new dbDataContext()) { return db.Customers.Where(c => c.InvoiceCount >= invoiceCount); } } What gets returned: {"d":[{"__type":"Customer","Account":"1116317","Name":"SOME COMPANY","Address":"UNit 1 , 392 JOHN ST. ","LastTransaction":"\/Date(1268294400000)\/","HighestBalance":13922.34},{"__type":"Customer","Account":"1116318","Name":"ANOTHER COMPANY","Address":"UNIT #345 , 392 JOHN ST. ","LastTransaction":"\/Date(1265097600000)\/","HighestBalance":549.42}]} What I'd LIKE to know, is what are people generally doing with this returned json? Do you iterate through the properties and create an html table on the fly? Is there way to "bind" JSON data using a javascript version of reflection ( something like the .Net GridView Control ) Do you throw this returned data into a Javascript Object and then do something with it? An example of what I want to achieve is to have an plain ol' html page ( on a mobile device )with a list of a Salesperson's Customers. When one of those customers are clicked, the customer id gets sent to a webservice which retrieves the customer details that are relevant to a sales person. I know the SO talent pool is quite deep so I figured you all here would be able to guide in the right direction and give me a few ideas on the best way to approach this.

  • How to find sum of node's value for given depth in binary tree?

    - by masato-san
    I've been scratching my head for several hours for this... problem: Binary Tree (0) depth 0 / \ 10 20 depth 1 / \ / \ 30 40 50 60 depth 2 I am trying to write a function that takes depth as argument and return the sum of values of nodes of the given depth. For instance, if I pass 2, it should return 180 (i.e. 30+40+50+60) I decided to use breath first search and when I find the node with desired depth, sum up the value, but I just can't figure out how to find out the way which node is in what depth. But with this approach I feel like going to totally wrong direction. function level_order($root, $targetDepth) { $q = new Queue(); $q->enqueue($root); while(!$q->isEmpty) { //how to determin the depth of the node??? $node = $q->dequeue(); if($currentDepth == $targetDepth) { $sum = $node->value; } if($node->left != null) { $q->enqueue($node->left); } if($node->right != null) { $q->enqueue($node->right); } //need to reset this somehow $currentDepth ++; } }

  • Slowing Down mywindow.print()

    - by TraderY
    I'm using this nice printing script: <script type="text/javascript"> function PrintElem(elem) { Popup($(elem).text()); } function Popup(data) { var mywindow = window.open('', 'my div', 'height=400,width=600'); mywindow.document.write('<html><head><title>my div</title>'); /*optional stylesheet*/ //mywindow.document.write('<link rel="stylesheet" href="main.css" type="text/css" />'); mywindow.document.write('</head><body >'); mywindow.document.write(data); mywindow.document.write('</body></html>'); mywindow.document.close(); mywindow.print(); return true; } </script> </head> <body> It works fine except for two things: mywindow.print() is triggered before the page has completely loaded so you can't see the material in the window to be printed (if you select "Print" it prints correctly though). The print dialog box opens on top of the window blocking the contents (presuming #1 is an easy fix). How can it positioned? Thanks - TY

  • Portable way of counting milliseconds in C++ ?

    - by ereOn
    Hi, Is there any portable (Windows & Linux) way of counting how many milliseconds elapsed between two calls ? Basically, I want to achieve the same functionnality than the StopWatch class of .NET. (for those who already used it) In a perfect world, I would have used boost::date_time but that's not an option here due to some silly rules I'm enforced to respect. For those who better read code, this is what I'd like to achieve. Timer timer; timer.start(); // Some instructions here timer.stop(); // Print out the elapsed time std::cout << "Elapsed time: " << timer.milliseconds() << "ms" << std::endl; So, if there is a portable (set of) function(s) that can help me implement the Timer class, what is it ? If there is no such function, what Windows & Linux API should I use to achieve this functionnality ? (using #ifdef WINDOWS-like macros) Thanks !

    I did not forget to add name attributes as is a common problem and yet my serialized form is returning an empty string. What am I doing wrong? HTML/javascript: <head> <script src="http://ajax.googleapis.com/ajax/libs/jquery/2.1.0/jquery.min.js"></script> <script> $( document ).ready( function() { $('#word_form').submit(function(e) { e.preventDefault(); console.log($(this).serialize()); //returns an empty string }); }); </script> </head> <body> <div id="wrapper"> <form name="word_form" id="word_form" method="POST"> <input type="image" name="thumbsUp" id="thumb1" value="1" src="http://upload.wikimedia.org/wikipedia/commons/8/87/Symbol_thumbs_up.svg" style="width:50px;height:50px;"> <input type="image" name="thumbsDown" id="thumb2" value="2" src="http://upload.wikimedia.org/wikipedia/commons/8/84/Symbol_thumbs_down.svg" style="width:50px;height:50px;"> </form> </div> </body> Thanks!
