  • MapReduce programming system in java-actionscript

    - by eco_bach
    Just finished reading ch23 in the excellent 'Beautiful Code' http://oreilly.com/catalog/9780596510046 on Distributed Programming with MapReduce. I understand that MapReduce is a programming system designed for large-scale data processing problems, but I have a hard time getting my head around the basic examples given and how I might apply them in real world situations. Can someone give a simple example of MapReduce implemented using either java, javascript or actionscript?

  • no DOM in wordpress admin

    - by Chris
    I correctly inserted a javascript file into the wordPress admin with : wp_enqueue_script() I know that the script is loading. I tested it with an alert(). I then found that I am unable to access the DOM. When I tried : document.getElementsByTagName('body')[0].addEventListener('load', function() {}); This error was: Uncaught TypeError: Cannot call method 'addEventListener' of undefined This is the first time I have used 'settings api' or inserted scripts into the WordPress admin.

  • Is there a way to extend controllers in sails.js

    - by alarner
    Often times I will want to perform some action on every page of my web application or make some method available to all of my controllers. In the past with object oriented MVC frameworks I would have all of my controllers extend a root controller, placing everything I wanted done on every page in the constructor of that root controller. How would I accomplish something similar with sails.js / javascript?

  • C#: Label contains no text

    - by Vinzcent
    Hey I would like to get the text out of a label. But the label text is set with Javascript. On the page I can see that there is text in the label, but when I debug it shows this: "". So how do I get the text out of a label that is set with Javascript, at least that is what I think is the problem. My code: <asp:TextBox ID="txtCount" runat="server" Width="50px" Font-Names="Georgia, Arial, sans-Serif" ForeColor="#444444"></asp:TextBox> <ajaxToolkit:NumericUpDownExtender ID="NumericUpDownExtender1" runat="server" Minimum="1" TargetButtonDownID="btnDown" TargetButtonUpID="btnUp" TargetControlID="txtCount" Width="20" /> <asp:ImageButton ID="btnUp" runat="server" AlternateText="up" ImageUrl="Images/arrowUp.png" OnClientClick="setAmountUp()" ImageAlign="Top" CausesValidation="False" /> <asp:ImageButton ID="btnDown" runat="server" AlternateText="down" ImageUrl="Images/arrowDown.png" OnClientClick="setAmountDown()" ImageAlign="Bottom" CausesValidation="False" /> <asp:Label ID="lblKorting" runat="server" /> <asp:Label ID="lblAmount" runat="server" /> <asp:Button ID="btnBestel" runat="server" CssClass="btn" Text="Bestel" OnClick="btnBestel_Click1" /> JS function setAmountUp() { var aantal = document.getElementById('<%=txtCount.ClientID%>').value-0; aantal+=1; calculateAmount(aantal); } function setAmountDown() { var aantal = document.getElementById('<%=txtCount.ClientID%>').value-0; if(aantal > 1) aantal -=1; calculateAmount(aantal); } function calculateAmount(aantal) { var prijs = document.getElementById('<%=lblPriceBestel.ClientID%>').innerHTML -0; var totaal = 0; if(aantal < 2) { totaal = prijs * aantal; document.getElementById('<%=lblKorting.ClientID%>').innerHTML = ""; } else if(aantal >= 2 && aantal < 5) { totaal = (prijs * aantal)*0.95; document.getElementById('<%=lblKorting.ClientID%>').innerHTML = "-5%"; } else if(aantal >= 5) { totaal = (prijs * aantal)*0.90; document.getElementById('<%=lblKorting.ClientID%>').innerHTML = "-10%"; } document.getElementById('<%=lblAmount.ClientID%>').innerHTML = totaal; } C# private OrderBO bestelling; protected void btnBestel_Click1(object sender, EventArgs e) { bestelling = new OrderBO(); bestelling.Amount = Convert.ToInt32(lblAmount.Text); //<--- THIS IS "" in the debugger, but on the page 10 }

  • Calling a function when a scrollbar appears in an IFrame

    - by chris
    I got an IFrame, in the onload event i set the height of the frame: function resizeFrame() { $("#iframeID").height($("#iframeID").contents().find("body").outerHeight(true)); } Problem is: When the content of the frame is increasing without a postback (javascript or Async Postback with Ajax), a scrollbar appears. I found a solution for Firefox: document.getElementById("iframeID").contentWindow.addEventListener("overflow", resizeFrame, false); But i can't find a solution for IE 7+8 Anyone got an idea?

  • client generated double submit cookie, cross site request forgery prevention

    - by james
    in a double-submitted cookie csrf prevention scheme, is it necessary for the server to provide the cookie? it seems i could have javascript on the clients page generate and set a cookie "anti_csrf", then double submit that (once as a cookie, done by the browser, and once in the body of the request). a foreign domain would not be able to read or write the "anti_csrf" cookie to include it in the body of a request. is this secure, or am i overlooking something?

  • Math.min.apply(0, x) - why?

    - by Trevor Burnham
    I was just digging through some JavaScript code (Raphaël.js) and came across the following line (translated slightly): Math.min.apply(0, x) where x is an array. Why on earth would you do this? The behavior seems to be "take the min from the array x."

  • Suppress "Done, but with errors on page" in IE

    - by calebthorne
    I have a website using lots of jQuery and JavaScript that produces a "Done, but with errors on page" message in the footer of IE. Everything on the site works perfectly, so I don't want to spend the time troubleshooting the exact error. All I would like to do is suppress the "Done, but with errors on page" message so that clients don't freak out. I tried the following at the top of the page with no success: window.onerror = function() {return true;}

    I have a canvas element defined statically in the html with a width and height. If I attempt to use JavaScript to resize it dynamically (setting a new width and height - either on the attributes of the canvas or via the style properties) I get the following error in Firefox: uncaught exception: [Exception... "Illegal operation on WrappedNative prototype object" nsresult: "0x8057000c (NS_ERROR_XPC_BAD_OP_ON_WN_PROTO)" location: "JS frame :: file:///home/russh/Desktop/test.html :: onclick :: line 1" data: no] Is it possible to resize this element or do I have to destroy it and create a new element on the fly?

  • Why is this widely used script killing my processor

    - by zac
    I installed this popular, light-weight script on a website but it is running very poorly and maxing out my processor. http://www.leigeber.com/2008/12/javascript-slideshow/ This is for sure my problem and nothing wrong with that script which runs fine for me on the demo site, but I have no errors and do not understand where the conflict lies. Any ideas on how to root this out?

  • jQuery Accordion /Tabs - Call different function upon load of content

    - by Scott
    I have the following markup: <body> <div id="tabs" style="float: left"> <ul> <li><a href="ajax/question_0.html" title="Question 1"><span>Question 1</span></a></li> <li><a href="ajax/question_1.html" title="Question 2"><span>Question 2</span></a></li> <li><a href="ajax/question_2.html" title="Question 3"><span>Question 3</span></a></li> <li><a href="ajax/question_3.html" title="Question 4"><span>Question 4</span></a></li> <li><a href="ajax/question_4.html" title="Question 5"><span>Question 5</span></a></li> <li><a href="ajax/question_5.html" title="Question 6"><span>Question 6</span></a></li> </ul> <div id="dynamicContent"> </div> </div> <div class="demo-description"> <p>Click tabs to see answers to Questions</p> </div> </body> I would like to utilize an accordion or the tabs plugin from the UI. Upon completion of the load event, I'd like to call a JavaScript function, but a different function for each tab -- almost like calling onDocumentReady for a page. I have the following JavaScript: $(function() { $('#tabs').tabs().bind('tabsselect', function(event, ui) { console.log("Loading: ajax/question_" + ui.index + ".html"); return true; //Ensure that the tab gets selected }); ); That's properly loading the Ajax file and all, but whenever I attempt to do something such as evaluating a statement in the JS, it seems to be ignored. Is there any way I can do this, so that once the file is loaded my function is called -- needs to be a different function for each tab.
