  • Displaying unnecessary HTML when showing content from MySQL database.

    - by ThatMacLad
    My homepage pulls in content from my MySQL database to create a blog. I've got it so that it only displays an extract from the posts. For some reason it displays HTML tags as well rather than formatting it using the tags (See picture below). Any help is appreciated. Homepage: <html> <head> <title>Ultan Casey | Homepage</title> <link rel="stylesheet" href="css/style.css" type="text/css" /> </head> <body> <div class="wrapper"> <div id="upperbar"> <a href="#">Home</a> <a href="#">About Me</a> <a href="#">Contact Me</a> <a href="http://www.twitter.com/UltanKC">Twitter</a> <form id="search-form" action="/search" method="get"> <input type="text" id="textarea" size="33" name="q" value=""/> <input type="submit" id="submit" value="Search"/> </form> </div> <div id="banner"> <img src="images/banner.jpg"> </div> <div class="sidebar"></div> <div class="posts"> <?php mysql_connect ('localhost', 'root', 'root') ; mysql_select_db ('tmlblog'); $sql = "SELECT * FROM php_blog ORDER BY timestamp DESC LIMIT 5"; $result = mysql_query($sql) or print ("Can't select entries from table php_blog.<br />" . $sql .

  • What's wrong with this jQuery? It isn't working as intended

    - by Doug Smith
    Using cookies, I want it to remember the colour layout of the page. (So, if they set the gallery one color and the body background another color, it will save that on refresh. But it doesn't seem to be working. jQuery: $(document).ready(function() { if (verifier == 1) { $('body').css('background', $.cookie('test_cookie')); } if (verifier == 2) { $('#gallery').css('background', $.cookie('test_cookie')); } if (verifier == 3) { $('body').css('background', $.cookie('test_cookie')); $('#gallery').css('background', $.cookie('test_cookie')); } $('#set_cookie').click(function() { var color = $('#set_cookie').val(); $.cookie('test_cookie', color); }); $('#set_page').click(function() { $('body').css('background', $.cookie('test_cookie')); var verifier = 1; }); $('#set_gallery').click(function() { $('#gallery').css('background', $.cookie('test_cookie')); var verifier = 2; }); $('#set_both').click(function() { $('body').css('background', $.cookie('test_cookie')); $('#gallery').css('background', $.cookie('test_cookie')); var verifier = 3; }); }); HTML: <p>Please select a background color for either the page's background, the gallery's background, or both.</p> <select id="set_cookie"> <option value="#1d375a" selected="selected">Default</option> <option value="black">Black</option> <option value="blue">Blue</option> <option value="brown">Brown</option> <option value="darkblue">Dark Blue</option> <option value="darkgreen">Dark Green</option> <option value="darkred">Dark Red</option> <option value="fuchsia">Fuchsia</option> <option value="green">Green</option> <option value="grey">Grey</option> <option value="#d3d3d3">Light Grey</option> <option value="#32cd32">Lime Green</option> <option value="#f8b040">Macaroni</option> <option value="#ff7300">Orange</option> <option value="pink">Pink</option> <option value="purple">Purple</option> <option value="red">Red</option> <option value="#0fcce0">Turquoise</option> <option value="white">White</option> <option value="yellow">Yellow</option> </select> <input type="button" id="set_page" value="Page's Background" /><input type="button" id="set_gallery" value="Gallery's Background" /><input type="button" id="set_both" value="Both" /> </div> </div> </body> </html> Thanks so much for the help, I appreciate it. jsFiddle: http://jsfiddle.net/hL6Ye/

  • Segfault on copy constructor for string

    - by user2756569
    I'm getting a segfault on a line where I'm creating a c++ string with the copy constructor. I've looked at some of the similar issues, but they're all due to passing in a bad c++ string object. I'm just passing in a raw string, so I'm not sure what my issue is. I'll paste the relevant snippets of code (it's taken from several different files, so it might look a bit jumbled). The segfault occurs in the 4th line of the default constructor for the Species class. Species::Species(string _type) { program_length = 0; cout << _type << " 1\n"; cout << type << " 2\n"; type = string(_type); } Grid::Grid(int _width, int _height) { *wall = Species("wall"); *empty = Species("empty"); turn_number = 0; width = _width; height = _height; for(int a= 0; a < 100; a++) for(int b = 0; b< 100; b++) { Creature empty_creature = Creature(*empty,a,b,NORTH,this); (Grid::map)[a][b] = empty_creature; } } int main() { Grid world = Grid(8,8); } class Grid { protected: Creature map[100][100]; int width,height; int turn_number; Species *empty; Species *wall; public: Grid(); Grid(int _width, int _height); void addCreature(Species &_species, int x, int y, Direction orientation); void addWall(int x, int y); void takeTurn(); void infect(int x, int y, Direction orientation, Species &_species); void hop(int x, int y, Direction orientation); bool ifWall(int x, int y, Direction orientation); bool ifEnemy(int x, int y, Direction orientation, Species &_species); bool ifEmpty(int x, int y, Direction orientation); void print(); }; class Species { protected: int program_length; string program[100]; string type; public: species(string _type); void addInstruction(string instruction); bool isWall(); bool isEmpty(); bool isEnemy(Species _enemy); string instructionAt(int index); string getType(); };

  • Cutting large XML file into smaller pieces in C#

    - by NDraskovic
    I have a problem that I'm working on for quite some time now. I have an XML file with over 50000 records (one record has 3 levels). This file is used by one of my applications to control document sending (the record holds, among other informations, the type of document that has to be sent to a certain person). So in my application I load the XML file into a XmlDocument, and then by using SelectNodes method, I create a XmlNodeList from which I read the data I want. The process is like this - our worker takes the persons ID card (simple eith barcode) and reads it with barcode reader. When the barcode value has been read, my application finds the person with that ID in the XML file, and stores the type of the document into a string variable. Then the worker takes the document and reads its barcode, and if the value of documents barcode and the value in the value in the string variable match, the application makes a record that document of type xxxxxxxx will be sent to the person with ID yyyyyyyyy. This is very simple code, it works perfectly for now, and this is how it looks: On textBox1_TextChanged event (worker read persons ID): foreach(XmlNode node in NodeList){ if(String.Compare(node.Attributes.GetNamedItem("ID").Value.ToString(),textBox1.Text)==0) { ControlString = node.ChildNode[3].FirstChild.Attributes.GetNamedItem("doctype").Value.ToString(); break; } } textBox2.Focus(); And on textBox2_TextChanged event (worker read the documents barcode): if(String.Compare(textBox2.Text,ControlString)==0) { //Create a record and insert it into a SQL database } My question is - how will my application perform with larger XML files (I was told that the XML file might be up to 500,000 records large), will this approach be valid, or will I need to cut the file into smaller files. If I have to cut it, please give me an idea with some code samples, I've tried to do it like this: Reading entire record and storing it into a string: private void WriteXml(XmlNode record) { tempXML = record.InnerXml; temp = "<" + record.Name + " code=\"" + record.Attributes.GetNamedItem("code").Value + "\">" + Environment.NewLine; temp += tempXML + Environment.NewLine; temp += "</" + record.Name + ">"; SmallerXMLDocument += temp + Environment.NewLine; temp = ""; i++; } tempXML, temp and SmallerXMLDocument are all string variables. And then in button_Click method I load the XML file into a XmlNodeList (again by using XmlDocument.SelectNodes method) and I try to create one big string value that would hold all records like this: foreach(XmlNode node in nodes) { if(String.Compare(node.ChildNode[3].FirstChild.Attributes.GetNamedItem("doctype").Value.ToString(),doctype1)==0) { WriteXML(node); } } My idea was to create a string value (in this case called SmallerXmlDocument), and when I pass trough the entire XML file, to simply copy the value of that string into a new file. This works, but only for files that have up to 2000 records (and my has way more than that). So, if I need to cut the file into smaller pieces, what would be the best way to do it (keep in mind that there could be up to half a million records in a XML file)? Thanks

  • C#: The input stream is not a valid binary format.

    - by Mcoroklo
    I have a problem with deserializing in C#/ASP.NET, which gives the exact error: The input stream is not a valid binary format. The starting contents (in bytes) are: 41-41-45-41-41-41-44-2F-2F-2F-2F-2F-41-51-41-41-41 ... What I am trying to do I have a structure with 3 classes. I have a class A which is a base class, and then class B and C which are derived from A. I am trying to store random types of B and C in the database using LINQ to SQL, in a column with the type VARCHAR(MAX). I cannot use BINARY as the length is around 15.000. My code...

  • I'm trying to return text from a .txt file using ajax

    - by saad
    I'm trying to get my first ajax script to work. The five images are all side by side. Whenever the user hovers the mouse over any of them, it sends a request to a .txt file on the server and the caption is displayed in the div#image_caption. The problem is, even when I mouse over the image, the caption does not display. I'm not quite sure what could be causing this. Here is the code <!DOCTYPE html> <html> <head> <style type="text/css"> div#images{overflow: auto;} img{float: left; width: 200px; height: 200px; margin-right: 15px;} div#image_caption {width: 1040px; height: 300px; margin-top: 30px; border: 2px black solid;} </style> <script type="text/javascript" src ="jquery-2.0.3.js"></script> <script type="text/javascript"> $(document).ready(function() { function show_caption(url) { //shows the caption once the mouse hovers over the image var asyncreq; if(window.XMLHttpRequest) { //IE 7+ and other browsers asyncreq = new XMLHttpRequest(); //define the request } else { //for IE 7- asyncreq = new ActiveXObject("Microsoft.XMLHTTP"); } asyncreq.open("GET", url, true); //give it properties asyncreq.send(); //send the request to the server asyncreq.onreadystatechange = function() { if(asyncreq.readyState == 4 && asyncreq.status == 200) { $("div#image_caption").html(asyncreq.responseText); //add the caption (response text from the file) to the box } } } //end of show_caption(url) function hide_caption() { //hides the caption once the mouse is gone $("div#image_caption").html(""); } }); </script> </head> <body> <h1>Hover over an image for more information.</h1> <div id = "images"> <img src="images/backg.jpg" mouseover = 'show_caption("backg_caption.txt");' mouseout = 'hide_caption();'/> <img src="images/Desert.jpg"mouseover = 'show_caption("Desert_caption.txt");' mouseout = 'hide_caption();'/> <img src="images/Penguins.jpg" mouseover = 'show_caption("Penguins_caption.txt");' mouseout = 'hide_caption();'/> <img src="images/Tulips.jpg" mouseover = 'show_caption("Tulips_caption.txt");' mouseout = 'hide_caption();'/> <img src="images/odji1.jpg" mouseover = 'show_caption("Desert_caption.txt");' mouseout = 'hide_caption();'/> </div> <div id = "image_caption"> </div> </body> </html>

  • Sending Javascript variables.

    - by shinjuo
    I have a page that allows a user to choose some things in a form and it will calculate the weight using javascript. It breaks it up into 5 variables that I need to send to another page. Originally I was just having it put the variable into a text box and then I was posting that text box. However I dont want to have 5 text boxes. So now I need to somehow send or post the five variables to another page. Here is my javascript function. I need to post weightBoxOne - weightBoxFive js function function getWeight(){ var weightBoxOne; var weightBoxTwo; var totalWeight; var box = .5; var quantity = document.dhform.quantity.value; var cardSize = document.dhform.cardSize.value; if(cardSize == 0.0141){ if(quantity <= 1000){ weightBoxOne = (quantity * cardSize) + box; totalWeight = weightBoxOne; }else if(quantity > 1000 && quantity <= 2000){ weightBoxOne = (1000 * cardSize) + box; weightBoxTwo = ((quantity - 1000) * cardSize) + box; totalWeight = weightBoxOne + weightBoxTwo; }else if(quantity > 2000 && quantity <= 3000){ weightBoxOne = (1000 * cardSize) + box; weightBoxTwo = (1000 * cardSize) + box; weightBoxThree = ((quantity - 2000) * cardSize) + box; totalWeight = weightBoxOne + weightBoxTwo + weightBoxThree; }else if(quantity > 3000 && quantity <= 4000){ weightBoxOne = (1000 * cardSize) + box; weightBoxTwo = (1000 * cardSize) + box; weightBoxThree = (1000 * cardSize) + box; weightBoxFour = ((quantity - 3000) * cardSize) + box; totalWeight = weightBoxOne + weightBoxTwo + weightBoxThree + weightBoxFour; }else{ weightBoxOne = (1000 * cardSize) + box; weightBoxTwo = (1000 * cardSize) + box; weightBoxThree = (1000 * cardSize) + box; weightBoxFour = (1000 * cardSize) + box; weightBoxFive = ((quantity - 4000) * cardSize) + box; totalWeight = weightBoxOne + weightBoxTwo + weightBoxThree + weightBoxFour + weightBoxFive; } }else if(cardSize == 0.00949){ if(quantity <= 4000){ weightBoxOne = (quantity * cardSize) + box; totalWeight = weightBoxOne; }else{ weightBoxOne = (4000 * cardSize) + box; weightBoxTwo = ((quantity - 4000) * cardSize) + box; totalWeight = weightBoxOne + weightBoxTwo; } } document.rates.weight.value = totalWeight; } //--> this is the form that was originally posting <form action="getRates.php" name="rates" method="post" onSubmit="popupform(this, 'join')"> <table style="width: 216px"> <tr> <td style="width: 115px; height: 49px;"><span class="style16">Weight</span><br/> <input type="text" id="weight" name="weight" size="10" maxlength="4"/> </td> <td align="right" style="width: 68px; height: 49px;" valign="top"><span class="style16">Zip Code</span><br/> <input type="text" id="zip" name="zip" size="10" maxlength="5"/> </td> </tr> <tr> <td style="width: 115px"> <input name="submit" type="submit" value="Get Rate Costs" style="width: 138px" />

  • Problem with PHP; Posting Hidden Value!!?

    - by Derek
    Hi, I have a page which basically allows an admin user to create manager user types (basically a register function. So when the values are submitted, they are stored into the DB, very very basic stuff. However, I have a hidden variable type..reasons are I have 3 different user levels and I have declared they identification as an integer (e.g. 7 = manager, 8 =user etc.) Can someone help me out with how to correctly pass this hidden value so it stores in the database... Here is my form: <form id="userreg" name="userreg" method="post" action="adminadduser-process.php"> <label>Full Name:</label> <input name="fullname" size="40" id="fullname" value="<?php if (isset($_POST['fullname'])); ?>"/> <br /> <label>Username:</label> <input name="username" size="40" id="username" value="<?php if (isset($_POST['username'])); ?>"/> <br /> <label>Password:</label> <input name="password" size="40" id="password" value="<?php if (isset($_POST['password'])); ?>"/> <br /> <label>Email Address:</label> <input name="emailaddress" size="40" id="emailaddress" value="<?php if (isset($_POST['emailaddress'])); ?>"/> <br /> <input name="userlevel" type="hidden" size="1" id="userlevel" value="<?php $_POST[5]; ?>" /> <br /> <input value="Add User" class="addbtn" type="submit" /> </form></div> Next, here is the script that runs the query: <?php require_once "config.php"; $fullname = $_POST['fullname']; $username = $_POST['username']; $password = $_POST['password']; $emailaddress = $_POST['emailaddress']; $userlevel = $_POST[5]; $sql = "INSERT INTO users_tb VALUES('".$user_id."','".$fullname."','".$username."',MD5('".$password."'),'".$emailaddress."','".$userlevel."')"; $result = mysql_query($sql, $connection) or die("MySQL Error: ".mysql_error()); header("Location: adminhome.php"); exit(); ?> I'm basically trying to pass the hidden typem with a constant value of '5' just for this form, as it will not be changed...also while im here, for some reason, the 'fullname' is not stored in the DB either!!?? WTH?? all other fields are processed fine. Any help is much appreciated! Thank you.

  • Retreiving multiple rows from a loop-created form... Stuck.

    - by hangston
    Hi All, Let me start by saying that I'm new to PHP, but I'm here to learn and would really appreciate your help. I use the following code to pull in data and create a form. This creates up to 40 lines for a user to fill out. Each line consists of the same information: Description, Amount, and Frequency. The remainder of the information needed is generated by the database. (See hidden fields) <?php $row = 0; do { $optid = $row_options['option_id']; echo "<tr>\n\t<td>" . htmlentities($row_options['option']) . "</td>\n"; echo "\t<td>" . "<input name='description' type='text' size='40' maxlength='120'/>" . "</td>\n"; echo "\t<td>" . "<input name='option_id' type='hidden' value='$optid' />$<input name='amount' type='text' size='10' maxlength='7'/>" . "</td>\n"; echo "\t<td>" . "<select name='assisted_frequency'> <option value='Monthly'>Monthly</option> <option value='Weekly'>Weekly</option> <option value='Daily'>Daily</option> <option value='Hourly'>Hourly</option> <option value='One-Time'>One-Time</option> </select>" . "</td>\n</tr>\n"; $array[$row] = array( $arraydesc[$row] = $_POST['description'], $arrayamto[$row] = $_POST['amount'], $arrayoptid[$row] = $optid, $arrayfreq[$row] = $_POST['frequency'], ); $row ++; } while ($row_options = mysql_fetch_assoc($options)); $counter = $row - 1; ?> I'm having troubles retrieving the information that the user inputs. My intent is to loop through each row after the user has input their information, then upload the mix of my database information and the user's information into another database. For example, the user would see, albeit prettier: form1 Option 1: description [input box] amount [input box] frequency [option box] Option 2: description [input box] amount [input box] frequency [option box] Option 3: description [input box] amount [input box] frequency [option box] Option 4: description [input box] amount [input box] frequency [option box] submit Upon submitting the form above, I'm using a query similar to the following to input the data into the database: for($row=0; $row<=$counter; $row++){ $insertSQL2 = sprintf("INSERT INTO table (option_id, amount, description, frequency) VALUES (%s, %s, %s, %s)", GetSQLValueString($arrayoptid[$row], "int"), GetSQLValueString($arrayamto[$row], "int"), GetSQLValueString($arraydesc[$row], "text"), GetSQLValueString($arrayfreq[$row], "text")); // code to submit query } I've tried for, foreach, arrays (what feels like the everything I know) to post each row (row by row) into the database. I either get just the last row of data, or no data at all. I also worry that the [$row] technique is adding characters to my data. What is the best way to retrieve each row of the user's inputs, then upload this data (row by row) into the database? Also, I would really appreciate your suggestions for improving my coding technique and the approach I'm taking. Thank you, Hangston

  • REST WCF service locks thread when called using AJAX in an ASP.Net site

    - by Jupaol
    I have a WCF REST service consumed in an ASP.Net site, from a page, using AJAX. I want to be able to call methods from my service async, which means I will have callback handlers in my javascript code and when the methods finish, the output will be updated. The methods should run in different threads, because each method will take different time to complete their task I have the code semi-working, but something strange is happening because the first time I execute the code after compiling, it works, running each call in a different threads but subsequent calls blocs the service, in such a way that each method call has to wait until the last call ends in order to execute the next one. And they are running on the same thread. I have had the same problem before when I was using Page Methods, and I solved it by disabling the session in the page but I have not figured it out how to do the same when consuming WCF REST services Note: Methods complete time (running them async should take only 7 sec and the result should be: Execute1 - Execute3 - Execute2) Execute1 -- 2 sec Execute2 -- 7 sec Execute3 -- 4 sec Output After compiling Output subsequent calls (this is the problem) I will post the code...I'll try to simplify it as much as I can Service Contract [ServiceContract( SessionMode = SessionMode.NotAllowed )] public interface IMyService { // I have other 3 methods like these: Execute2 and Execute3 [OperationContract] [WebInvoke( RequestFormat = WebMessageFormat.Json, ResponseFormat = WebMessageFormat.Json, UriTemplate = "/Execute1", Method = "POST")] string Execute1(string param); } [AspNetCompatibilityRequirements(RequirementsMode = AspNetCompatibilityRequirementsMode.Allowed)] [ServiceBehavior( InstanceContextMode = InstanceContextMode.PerCall )] public class MyService : IMyService { // I have other 3 methods like these: Execute2 (7 sec) and Execute3(4 sec) public string Execute1(string param) { var t = Observable.Start(() => Thread.Sleep(2000), Scheduler.NewThread); t.First(); return string.Format("Execute1 on: {0} count: {1} at: {2} thread: {3}", param, "0", DateTime.Now.ToString(), Thread.CurrentThread.ManagedThreadId.ToString()); } } ASPX page <%@ Page EnableSessionState="False" Title="Home Page" Language="C#" MasterPageFile="~/Site.master" AutoEventWireup="true" CodeBehind="Default.aspx.cs" Inherits="RestService._Default" %> <asp:Content ID="HeaderContent" runat="server" ContentPlaceHolderID="HeadContent"> <script type="text/javascript"> function callMethodAsync(url, data) { $("#message").append("<br/>" + new Date()); $.ajax({ cache: false, type: "POST", async: true, url: url, data: '"de"', contentType: "application/json", dataType: "json", success: function (msg) { $("#message").append("<br/>&nbsp;&nbsp;&nbsp;" + msg); }, error: function (xhr) { alert(xhr.responseText); } }); } $(function () { $("#callMany").click(function () { $("#message").html(""); callMethodAsync("/Execute1", "hello"); callMethodAsync("/Execute2", "crazy"); callMethodAsync("/Execute3", "world"); }); }); </script> </asp:Content> <asp:Content ID="BodyContent" runat="server" ContentPlaceHolderID="MainContent"> <input type="button" id="callMany" value="Post Many" /> <div id="message"> </div> </asp:Content> Web.config (relevant) <system.webServer> <modules runAllManagedModulesForAllRequests="true" /> </system.webServer> <system.serviceModel> <serviceHostingEnvironment aspNetCompatibilityEnabled="true" multipleSiteBindingsEnabled="true" /> <standardEndpoints> <webHttpEndpoint> <standardEndpoint name="" helpEnabled="true" automaticFormatSelectionEnabled="true" /> </webHttpEndpoint> </standardEndpoints> </system.serviceModel> Global.asax void Application_Start(object sender, EventArgs e) { RouteTable.Routes.Ignore("{resource}.axd/{*pathInfo}"); RouteTable.Routes.Add(new ServiceRoute("", new WebServiceHostFactory(), typeof(MyService))); }

  • Is this a SEO SAFE anchor link

    - by Mayhem
    so... Is this a safe way to use internal links on your site.. By doing this i have the index page generating the usual php content section and handing it to the div element. THE MAIN QUESTION: Will google still index the pages using this method? Common sense tells me it does.. But just double checking and leaving this here as a base example as well if it is. As in. EXAMPLE ONLY PEOPLE The Server Side if (isset($_REQUEST['page'])) {$pageID=$_REQUEST['page'];} else {$pageID="home";} if (isset($_REQUEST['pageMode']) && $_REQUEST['pageMode']=="js") { require "content/".$pageID.".php"; exit; } // ELSE - REST OF WEBSITE WILL BE GENERATED USING THE page VARIABLE The Links <a class='btnMenu' href='?page=home'>Home Page</a> <a class='btnMenu' href='?page=about'>About</a> <a class='btnMenu' href='?page=Services'>Services</a> <a class='btnMenu' href='?page=contact'>Contact</a> The Javascript $(function() { $(".btnMenu").click(function(){return doNav(this);}); }); function doNav(objCaller) { var sPage = $(objCaller).attr("href").substring(6,255); $.get("index.php", { page: sPage, pageMode: 'js'}, function(data) { ("#siteContent").html(data).scrollTop(0); }); return false; } Forgive me if there are any errors, as just copied and pasted from my script then removed a bunch of junk to simplify it as still prototyping/white boarding the project its in. So yes it does look a little nasty at the moment. REASONS WHY: The main reason is bandwidth and speed, This will allow other scripts to run and control the site/application a little better and yes it will need to be locked down with some coding. -- FURTHER EXAMPLE-- INSERT PHP AT TOP <?php // PHP CODE HERE ?> <html> <head> <link rel="stylesheet" type="text/css" href="style.css" /> <script type="text/javascript" src="jquery.js"></script> <script type="text/javascript" src="scripts.js"></script> </head> <body> <div class='siteBody'> <div class='siteHeader'> <?php foreach ($pageList as $key => $value) { if ($pageID == $key) {$btnClass="btnMenuSel";} else {$btnClass="btnMenu";} echo "<a class='$btnClass' href='?page=".$key."'>".$pageList[$key]."</a>"; } ?> </div><div id="siteContent" style='margin-top:10px;'> <?php require "content/".$pageID.".php"; ?> </div><div class='siteFooter'> </div> </div> </body> </html>

  • Handling a Long Running jsp request on the server using Ajax and threads

    - by John Blue
    I am trying to implement a solution for a long running process on the server where it is taking about 10 min to process a pdf generation request. The browser bored/timesout at the 5 mins. I was thinking to deal with this using a Ajax and threads. I am using regular javascript for ajax. But I am stuck with it. I have reached till the point where it sends the request to the servlet and the servlet starts the thread.Please see the below code public class HelloServlet extends javax.servlet.http.HttpServlet implements javax.servlet.Servlet { protected void doGet(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException { } protected void doPost(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException { System.out.println("POST request!!"); LongProcess longProcess = new LongProcess(); longProcess.setDaemon(true); longProcess.start(); request.getSession().setAttribute("longProcess", longProcess); request.getRequestDispatcher("index.jsp").forward(request, response); } } class LongProcess extends Thread { public void run() { System.out.println("Thread Started!!"); while (progress < 10) { try { sleep(2000); } catch (InterruptedException ignore) {} progress++; } } } Here is my AJax call <!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd"> <html><head> <meta http-equiv="Content-Type" content="text/html; charset=ISO-8859-1"> <title>My Title</title> <script language="JavaScript" > function getXMLObject() //XML OBJECT { var xmlHttp = false; xmlHttp = new XMLHttpRequest(); //For Mozilla, Opera Browsers return xmlHttp; // Mandatory Statement returning the ajax object created } var xmlhttp = new getXMLObject(); //xmlhttp holds the ajax object function ajaxFunction() { xmlhttp.open("GET","HelloServlet" ,true); xmlhttp.onreadystatechange = handleServerResponse; xmlhttp.setRequestHeader('Content-Type', 'application/x-www-form-urlencoded'); xmlhttp.send(null); } function handleServerResponse() { if (xmlhttp.readyState == 4) { if(xmlhttp.status == 200) { document.forms[0].myDiv.value = xmlhttp.responseText; setTimeout(ajaxFunction(), 2000); } else { alert("Error during AJAX call. Please try again"); } } } function openPDF() { document.forms[0].method = "POST"; document.forms[0].action = "HelloServlet"; document.forms[0].submit(); } function stopAjax(){ clearInterval(intervalID); } </script> </head> <body><form name="myForm"> <table><tr><td> <INPUT TYPE="BUTTON" NAME="Download" VALUE="Download Queue ( PDF )" onclick="openPDF();"> </td></tr> <tr><td> Current status: <div id="myDiv"></div>% </td></tr></table> </form></body></html> But I dont know how to proceed further like how will the thread communicate the browser that the process has complete and how should the ajax call me made and check the status of the request. Please let me know if I am missing some pieces. Any suggestion if helpful.

  • Form gets submitted Multiple times

    - by rasika vijay
    While clicking inside the form , the form automatically tried to resubmit , I cannot figure out which part of the code causes it to behave like this . In the createTable function , a table is created after the domain is given . But I am unable to select any of the controls in the output . I have attached the jsfiddle code link here : http://jsfiddle.net/rasikaceg/S7kWM/ function createTable() { document.getElementById("table_container").innerHTML = ""; var input_domain = document.forms["form1"]["DomainName"].value; if (input_domain == null || input_domain == "") return; var table = document.createElement("table"), tablehead = document.createElement("thead"), theadrow = document.createElement("tr"), th1 = document.createElement("th"), th2 = document.createElement("th"), th3 = document.createElement("th"), th4 = document.createElement("th"); th1.appendChild(document.createTextNode("Website")); th2.appendChild(document.createTextNode("Enable/Disable Live Update for LM and CBD")); th3.appendChild(document.createTextNode("From Date")); th4.appendChild(document.createTextNode("To Date")); theadrow.appendChild(th1); theadrow.appendChild(th2); theadrow.appendChild(th3); theadrow.appendChild(th4); tablehead.appendChild(theadrow); table.appendChild(tablehead); var names = ["website1", "website2"]; var container = document.getElementById("table_container"); var tablebody = document.createElement("tbody"); for (var i = 0, len = names.length; i < len; ++i) { var row = document.createElement("tr"), column1 = document.createElement("td"), column2 = document.createElement("td"), column3 = document.createElement("td"), column4 = document.createElement("td"), checkbox = document.createElement('input'); checkbox.type = "checkbox"; checkbox.name = names[i]; checkbox.value = names[i]; checkbox.id = names[i]; var label = document.createElement('label') label.htmlFor = names[i]; label.appendChild(document.createTextNode(names[i])); column1.appendChild(checkbox); column1.appendChild(label); var dropdown = document.createElement("select"); dropdown.name = names[i] + "_select"; var op1 = new Option(); op1.value = "enable"; op1.text = "enable"; var op2 = new Option(); op2.value = "disable"; op2.text = "disable"; dropdown.options.add(op1); dropdown.options.add(op2); column2.appendChild(dropdown); var datetime_from = document.createElement('input'); datetime_from.type = "datetime-local"; datetime_from.name = names[i] + "_from"; column3.appendChild(datetime_from); var datetime_to = document.createElement('input'); datetime_to.type = "datetime-local"; datetime_to.name = names[i] + "_to"; column4.appendChild(datetime_to); row.appendChild(column1); row.appendChild(column2); row.appendChild(column3); row.appendChild(column4); tablebody.appendChild(row); } table.appendChild(tablebody); document.getElementById("table_container").appendChild(table); }

  • Haskell: monadic takeWhile?

    - by Mark Rushakoff
    I have some functions written in C that I call from Haskell. These functions return IO (CInt). Sometimes I want to run all of the functions regardless of what any of them return, and this is easy. For sake of example code, this is the general idea of what's happening currently: Prelude> let f x = print x >> return x Prelude> mapM_ f [0..5] 0 1 2 3 4 5 Prelude> I get my desired side effects, and I don't care about the results. But now I need to stop execution immediately after the first item that doesn't return my desired result. Let's say a return value of 4 or higher requires execution to stop - then what I want to do is this: Prelude> takeWhile (<4) $ mapM f [0..5] Which gives me this error: <interactive:1:22: Couldn't match expected type `[b]' against inferred type `IO a' In the first argument of `mapM', namely `f' In the second argument of `($)', namely `mapM f ([0 .. 5])' In the expression: takeWhile (< 4) $ mapM f ([0 .. 5]) And that makes sense to me - the result is still contained in the IO monad, and I can't just compare two values contained in the IO monad. I know this is precisely the purpose of monads -- chaining results together and discarding operations when a certain condition is met -- but is there an easy way to "wrap up" the IO monad in this case to stop executing the chain upon a condition of my choosing, without writing an instance of MonadPlus? Can I just "unlift" the values from f, for the purposes of the takeWhile? Is this a solution where functors fit? Functors haven't "clicked" with me yet, but I sort of have the impression that this might be a good situation to use them. Update: @sth has the closest answer to what I want - in fact, that's almost exactly what I was going for, but I'd still like to see whether there is a standard solution that isn't explicitly recursive -- this is Haskell, after all! Looking back on how I worded my question, now I can see that I wasn't clear enough about my desired behavior. The f function I used above for an example was merely an example. The real functions are written in C and used exclusively for their side effects. I can't use @Tom's suggestion of mapM_ f (takeWhile (&lt;4) [0..5]) because I have no idea whether any input will really result in success or failure until executed. I don't actually care about the returned list, either -- I just want to call the C functions until either the list is exhausted or the first C function returns a failure code. In C-style pseudocode, my behavior would be: do { result = function_with_side_effects(input_list[index++]); } while (result == success && index < max_index); So again, @sth's answer performs the exact behavior that I want, except that the results may (should?) be discarded. A dropWhileM_ function would be equivalent for my purposes. Why isn't there a function like that or takeWhileM_ in Control.Monad? I see that there was a similar discussion on a mailing list, but it appears that nothing has come of that.

  • What's my best approach on this simple hierarchy Java Problem?

    - by Nazgulled
    First, I'm sorry for the question title but I can't think of a better one to describe my problem. Feel free to change it :) Let's say I have this abstract class Box which implements a couple of constructors, methods and whatever on some private variables. Then I have a couple of sub classes like BoxA and BoxB. Both of these implement extra things. Now I have another abstract class Shape and a few sub classes like Square and Circle. For both BoxA and BoxB I need to have a list of Shape objects but I need to make sure that only Square objects go into BoxA's list and only Circle objects go into BoxB's list. For that list (on each box), I need to have a get() and set() method and also a addShape() and removeShape() methods. Another important thing to know is that for each box created, either BoxA or BoxB, each respectively Shape list is exactly the same. Let's say I create a list of Square's named ls and two BoxA objects named boxA1 and boxA2. No matter what, both boxA1 and boxA2 must have the same ls list. This is my idea: public abstract class Box { // private instance variables public Box() { // constructor stuff } // public instance methods } public class BoxA extends Box { // private instance variables private static List<Shape> list; public BoxA() { // constructor stuff } // public instance methods public static List<Square> getList() { List<Square> aux = new ArrayList<Square>(); for(Square s : list.values()) { aux.add(s.clone()); // I know what I'm doing with this clone, don't worry about it } return aux; } public static void setList(List<Square> newList) { list = new ArrayList<Square>(newList); } public static void addShape(Square s) { list.add(s); } public static void removeShape(Square s) { list.remove(list.indexOf(s)); } } As the list needs to be the same for that type of object, I declared as static and all methods that work with that list are also static. Now, for BoxB the class would be almost the same regarding the list stuff. I would only replace Square by Triangle and the problem was solved. So, for each BoxA object created, the list would be only one and the same for each BoxB object created, but a different type of list of course. So, what's my problem you ask? Well, I don't like the code... The getList(), setList(), addShape() and removeShape() methods are basically repeated for BoxA and BoxB, only the type of the objects that the list will hold is different. I can't think of way to do it in the super class Box instead. Doing it statically too, using Shape instead of Square and Triangle, wouldn't work because the list would be only one and I need it to be only one but for each sub class of Box. How could I do this differently and better? P.S: I could not describe my real example because I don't know the correct words in English for the stuff I'm doing, so I just used a box and shapes example, but it's basically the same.
