  • Terminate function on System.in .. possible?

    - by Ronald
    I am currently working on a project where I have to make an agent to interact with a server. Each 50ms, the server will receive the last thing I outputted to System.out and send me a new set of lines as a 'state' through the System.in printstream to analyze and send my next message to System.out. Also, if the server receives multiple outputs from me, it only regards the most recent one. .. As for my question: My program originally constructed a tree and then analyzed each leaf node to see which would be optimal, and then waited around for the next input, but I can recursively do a deeper tree search that would make my output 'better' (and again and again to keep returning a better result). Using this and the fact that if the server receives multiple outputs, it only takes the most recent one, I could do each level, print my result and start the next level. But here comes my problem... I can't be stuck in some complex algorithm while I am supposed to receiving the next input as I will then miss it. So I was wondering if there is a way to cancel anything else I am doing when I receive something via System.in and then go back to the beginning of the function and start the search again with the new set of input (and rinse and repeat..) I hope this all makes sense, Thank ye all

  • Why am I losing my characters from my html string when trying to add html dynamically using javascri

    - by Hamman359
    I have a page that I am trying to dynamically add some links to. The links are getting added to the page fine, but the '[' and ']' at either end of the line are getting dropped. The code from my .js file is: var html = "[ <a href='#'>Change</a>&nbsp;|&nbsp;<a href='#'>Remove </a> ]"; $(html).appendTo("#id123"); The result I want is: [ <a href='#'>Change</a>&nbsp;|&nbsp;<a href='#'>Remove</a> ] The result I'm getting is: <a href='#'>Change</a>&nbsp;|&nbsp;<a href='#'>Remove</a> If I wrap the line in a <span> tag like so: var html = "<span>[ <a href='#'>Change</a>&nbsp;|&nbsp;<a href='#'>Remove </a> ]</span>"; $(html).appendTo("#id123"); it renders as expected. I set a breakpoint on the code and checked the html var right before the .appendTo and it contains the '[' and ']'. Anyone know why this is happening? Are '[' and ']' special character that need escaped and I'm just forgetting that fact?

  • jQuery - I'm getting unexpected outputs from a basic math formula.

    - by OllieMcCarthy
    Hi I would like to start by saying I'd greatly appreciate anyones help on this. I have built a small caculator to calculate the amount a consumer can save annually on energy by installing a ground heat pump or solar panels. As far as I can tell the mathematical formulas are correct and my client verified this yesterday when I showed him the code. Two problems. The first is that the calculator is outputting ridiculously large numbers for the first result. The second problem is that the solar result is only working when there are no zeros in the fields. Are there some quirks as to how one would write mathematical formulas in JS or jQuery? Any help greatly appreciated. Here is the link - http://www.olliemccarthy.com/test/johncmurphy/?page_id=249 And here is the code for the entire function - $jq(document).ready(function(){ // Energy Bill Saver // Declare Variables var A = ""; // Input for Oil var B = ""; // Input for Storage Heater var C = ""; // Input for Natural Gas var D = ""; // Input for LPG var E = ""; // Input for Coal var F = ""; // Input for Wood Pellets var G = ""; // Input for Number of Occupants var J = ""; var K = ""; var H = ""; var I = ""; // Declare Constants var a = "0.0816"; // Rate for Oil var b = "0.0963"; // Rate for NightRate var c = "0.0558"; // Rate for Gas var d = "0.1579"; // Rate for LPG var e = "0.121"; // Rate for Coal var f = "0.0828"; // Rate for Pellets var g = "0.02675"; // Rate for Heat Pump var x = "1226.4"; // Splittin up I to avoid error var S1 = ""; // Splitting up the calcuation for I var S2 = ""; // Splitting up the calcuation for I var S3 = ""; // Splitting up the calcuation for I var S4 = ""; // Splitting up the calcuation for I var S5 = ""; // Splitting up the calcuation for I var S6 = ""; // Splitting up the calcuation for I // Calculate H (Ground Sourced Heat Pump) $jq(".es-calculate").click(function(){ $jq(".es-result-wrap").slideDown(300); A = $jq("input.es-oil").val(); B = $jq("input.es-storage").val(); C = $jq("input.es-gas").val(); D = $jq("input.es-lpg").val(); E = $jq("input.es-coal").val(); F = $jq("input.es-pellets").val(); G = $jq("input.es-occupants").val(); J = ( A / a ) + ( B / b ) + ( C / c ) + ( D / d ) + ( E / e ) + ( F / f ) ; H = A + B + C + D + E + F - ( J * g ) ; K = ( G * x ) ; if ( A !== "0" ) { S1 = ( ( ( A / a ) / J ) * K * a ) ; } else { S1 = "0" ; } if ( B !== "0" ) { S2 = ( ( ( B / b ) / J ) * K * b ) ; } else { S2 = "0" ; } if ( C !== "0" ) { S3 = ( ( ( C / c ) / J ) * K * c ) ; } else { S3 = "0" ; } if ( D !== "0" ) { S4 = ( ( ( D / d ) / J ) * K * d ) ; } else { S4 = "0" ; } if ( E !== "0" ) { S5 = ( ( ( E / e ) / J ) * K * e ) ; } else { S5 = "0" ; } if ( F !== "0" ) { S6 = ( ( ( F / f ) / J ) * K * f ) ; } else { S6 = "0" ; } I = S1 + S2 + S3 + S4 + S5 + S6 ; if(!isNaN(H)) {$jq("span.es-result-span-h").text(H.toFixed(2));} else{$jq("span.es-result-span-h").text('Error: Please enter numerals only');} if(!isNaN(I)) {$jq("span.es-result-span-i").text(I.toFixed(2));} else{$jq("span.es-result-span-i").text('Error: Please enter numerals only');} }); });

    I'm using JQuery and Prototype in this web application that I'm developing. I'm looking for a way to use Lightbox v2.04 by Lokesh Dhakar to play flash movies.

The reason I'm set on v2.04 is because I'm using it already as an image gallery. I'm using flv type flash files if that helps.

  • How to navigate to another html page?

    - by newbie
    In my application there's a usual login page sending username and password to the server script, where it needs to be authenticated, and in case of an authentic user, the server should redirect to a page student.html. This is my code var ports = 3000; var portt = 3001; var express = require('express'); var student = require('express')(); var teacher = require('express')(); var server_s = require('http').createServer(student); var server_t = require('http').createServer(teacher); var ios = require('socket.io').listen(server_s); var iot = require('socket.io').listen(server_t); var path = require('path'); server_s.listen(ports); server_t.listen(portt); student.use(express.static(path.join(__dirname, 'public'))); student.get('/', function(req,res){ res.sendfile(__dirname + '/login.html'); }); teacher.use(express.static(path.join(__dirname, 'public'))); teacher.get('/', function(req,res){ res.sendfile(__dirname + '/mytry.html'); }); ios.sockets.on('connection', function(socket){ var username, password; socket.on('check',function(data){ username = data[0]; password = data[1]; //************* Database connection and query ************* var mysql = require('mysql'); var connection = mysql.createConnection({ host : 'localhost', user : 'user', password: '*******', database: 'my_db' }); connection.connect(); var qstring = 'SELECT s_id FROM login_student WHERE username='+username+'AND password='+password; connection.query(qstring, function(err, rows, fields) { if (err) { console.log('ERROR: ' + err); socket.emit('login_failure','DB error'); return; } console.log('The solution is: ', rows[0].solution); if (rows>0) //***** Here i want redirection to another page ****** else socket.emit('login_failure','Invalid Username or password'); }); connection.end(); }); }); iot.sockets.on('connection', function(socket){ ; }); }); Can anyone suggest what should I do?

  • Understanding a skeleton of jQuery plugin

    - by TK
    At a website, I found the following code to make a jQuery plugin: (function($){ // Our code here... })(jQuery); I don't understand how the code above works. What I understand is that the code executes immediately because the very last () in function(){}(). So the entire code says that is an anonymous function that is run immediately. But I don't understand why the wrapping needs to pass jQuery and that inside it needs $ to be passed. From my understanding, $ is an alias to jQuery, meaning practically the same. What is the meaning of $ and jQuery here? How does the overall code work as a jQuery plugin?

  • Loop through Json object

    - by Tanmoy
    I have a JSON object like the following var p = { "p1": "value1", "p2": "value2", "p3": "value3" }; Now I want to loop through all p elements (p1,p2,p3...) and get their key and values. How can I do that? I can modify the Json object if necessary . My ultimate goal is to loop through some key value pairs. And if possible I want to avoid using eval.

  • jQuery-Ui Ajax Tabs bug?

    - by vsync
    I have a JSON that returns from the server which tabs to build, so I init them in my JS like this: $('#tabs').tabs( 'ajaxOptions', { timeout: 20000, error: function(xhr, status, index, anchor){ console.log( status, index, anchor ); } }) .tabs('add', item.CategoryLink, item.CategoryName); Thing is, when I click a tab, and before it is done loading I click another tab, the previous request is aborted and never called again when I click that first one again! this is very bad, because it obviously didn't fetch the request, so what gives? I tried bypassing this by setting: .tabs({ cache: false }) but this is a bad thing to do, because I don't want to have a request each time again... it should be cachced if response was sent. using jquery-ui 1.8.1

  • Word wrap in multiline textbox after 35 characters

    - by Kanavi
    <asp:TextBox CssClass="txt" ID="TextBox1" runat="server" onkeyup="CountChars(this);" Rows="20" Columns="35" TextMode="MultiLine" Wrap="true"> </asp:TextBox> I need to implement word-wrapping in a multi-line textbox. I cannot allow users to write more then 35 chars a line. I am using the following code, which breaks at precisely the specified character on every line, cutting words in half. Can we fix this so that if there's not enough space left for a word on the current line, we move the whole word to the next line? function CountChars(ID) { var IntermediateText = ''; var FinalText = ''; var SubText = ''; var text = document.getElementById(ID.id).value; var lines = text.split("\n"); for (var i = 0; i < lines.length; i++) { IntermediateText = lines[i]; if (IntermediateText.length <= 50) { if (lines.length - 1 == i) FinalText += IntermediateText; else FinalText += IntermediateText + "\n"; } else { while (IntermediateText.length > 50) { SubText = IntermediateText.substring(0, 50); FinalText += SubText + "\n"; IntermediateText = IntermediateText.replace(SubText, ''); } if (IntermediateText != '') { if (lines.length - 1 == i) FinalText += IntermediateText; else FinalText += IntermediateText + "\n"; } } } document.getElementById(ID.id).value = FinalText; $('#' + ID.id).scrollTop($('#' + ID.id)[0].scrollHeight); } Edit - 1 I have to show total max 35 characters in line without specific word break and need to keep margin of two characters from the right. Again, the restriction should be for 35 characters but need space for total 37 (Just for the Visibility issue.)

  • function returns after an XMLHttpRequest

    - by ashays
    Alright, I know questions like this have probably been asked dozens of times, but I can't seem to find a working solution for my project. Recently, while using jQuery for a lot of AJAX calls, I've found myself in a form of callback hell. Whether or not jQuery is too powerful for this project is beyond the scope of this question. So basically here's some code that shows what's going on: function check_form(table) { var file = "/models/"+table+".json"; var errs = {}; var xhr = $.getJSON(file, function(json) { for (key in json) { var k = key; var r = json[k]; $.extend(errs, check_item("#"+k,r)); } }); return errs; } And... as you can probably guess, I get an empty object returned. My original idea was to use some sort of onReadyStateChange idea that would return whenever the readyState had finally hit 4. This causes my application to hang indefinitely, though. I need these errors to decide whether or not the form is allowed to submit or not (as well as to tell the user where the errors are in the application. Any ideas? Edit. It's not the prettiest solution, but I've managed to get it to work. Basically, check_form has the json passed to it from another function, instead of loading it. I was already loading it there, too, so it's probably best that I don't continue to load the same file over and over again anyways. I was just worried about overloading memory. These files aren't absolutely huge, though, so I guess it's probably okay.

  • Permission denied to access property 'toString'

    I'm trying to find a generic way of getting the name of Constructors. My goal is to create a Convention over configuration framework for KnockoutJS My idea is to iterate over all objects in the window and when I find the contructor i'm looking for then I can use the index to get the name of the contructor The code sofar (function() { constructors = {}; window.findConstructorName = function(instance) { var constructor = instance.constructor; var name = constructors[constructor]; if(name !== undefined) { return name; } var traversed = []; var nestedFind = function(root) { if(typeof root == "function" || traversed[root]) { return } traversed[root] = true; for(var index in root) { if(root[index] == constructor) { return index; } var found = nestedFind(root[index]); if(found !== undefined) { return found; } } } name = nestedFind(window); constructors[constructor] = name; return name; } })(); var MyApp = {}; MyApp.Foo = function() { }; var instance = new MyApp.Foo(); console.log(findConstructorName(instance)); The problem is that I get a Permission denied to access property 'toString' Exception, and i cant even try catch so see which object is causing the problem Fiddle http://jsfiddle.net/4ZwaV/

  • Checking if radio buttons are checked in Firefox

    - by Andrew Song
    On my site, I have two checkboxes created in my ASP.NET MVC view like so: Html.RadioButton("check", "true", "true" == (string) ViewData["someKey"], new { id = "check1"}); Html.RadioButton("check", "false", "false" == (string) ViewData["someKey"], new { id = "check2"}); I am positive that ViewData["someKey"] has the value "true" in it. In my JS init function, I perform the following check: alert($('#check1').is(':checked') + " " + $('#check2').is(':checked')); In Firefox (and only Firefox), my alert dialog will show the following (it works as expected in every other browser): Initial page load: true false Normal refresh via Ctrl + R: false false Refresh skipping cache via Ctrl + Shift + R: true false I have tried many different methods of looking at the checkbox value, including $('#check1').attr('checked') without success. If I examine the HTML in Firebug, I can see that the first radio button has the property checked="checked" in it. Why is the checkbox value changing in FF when I refresh, and how can I mitigate this? Since this seems to be a FF-only bug, how can I change my code to make it work? This SO question seemed to ask something similar, but none of the proposed solutions seem to work in this case. Edit: I should also point out that when the radio button is rendered after the refresh in FF, it's not actually being displayed as checked either, despite what the HTML is telling me. Edit2: Adding raw HTML as per request <input id="check1" type="radio" value="True" name="check" checked="checked"/> <input id="check2" type="radio" value="False" name="check"/>

  • JSON.Stringify data including boolean values

    What I'm trying to do is to pass JSON object to a WebAPI ajax call and mapped to a strongly typed object on the server side. String values are being posted perfectly however when it comes to boolean values, they are not being passed at all. Below is my code: var gsGasolineField = $('.gsGasoline').val(); blData = { Gasoline: gsGasolineField }; var json = JSON.stringify(blData); $.ajax({ type: "POST", url: url, data: json, contentType: "application/json", dataType: "json", statusCode: { 201 /*Created"*/: function (data) { $("#BusinessLayerDialog").dialog("close"); ClearForm("#BusinessLayerForm"); }, 400: /*Bad request - validation error*/ function (data) { $("#BusinessLayerForm").validate().form(); }, 500: function (data) { alert('err'); } }, beforeSend: setHeader }); Gasoline property is of type boolean on the server side.
