  • Why does my table values return nil when i clearly initialized them?

    - by user3717078
    players = {} function newPlayer(name) players[name]={x = 200, y = 100} --assign each player their x and y coordinates, which is x: 200 and y: 100 end function checkPosition(name?) -- Do i need a parameter? if players[name].x == 200 and players[name].y == 100 then --says players[name].x is a nil value print("good") else print("bad") end end Error: attempt to index ?

  • Changing the href attribute on hover with jQuery

    - by AverageJoe
    Ok, I have an html page that is loaded into another html page via PHP (ok so its a PHP page, whatever). The page that is loaded is a list of hyperlinks. I need to change the href attribute to make the hyperlinks relative to the location of the stored images they refer too. When i load the page containing the hyperlinks the links are relative to the web host server, not the server that the page is actually hosted from. Somthing like this: <div #screenshots) <p><a href="image1.htm">Image1</a></p> <p><a href="image2.htm">Image2</a></p> <p><a href="image3.htm">Image3</a></p> <p><a href="image4.htm">Image4</a></p> <p><a href="image5.htm">Image5</a></p> </div> When I mouse over the links, the status bar shows the reference as "http://webHostServer.com/image1.htm". If I click it I get a 404 error. I need the href to change to something like this when I mouse over it: "http://www.actualImageHostServerIPaddress/image1.htm" I looked at this for assitance and came out with the following jQuery code, but for some reason none of it works: $(document).ready(function(){ $("button").click(function() { $("#screenshots a").addClass('ss'); }); $(".ss").each(function() { $(this).data("oldHref", $(this).attr("href")); orig = $(this).attr("href"); over = "http://208.167.244.33/208.167.244.33/"; $(this).hover(function() { $(this).attr("href", $(this).attr("href").replace(orig, over+orig)); }, function() { $(this).attr("href", $(this).data("oldHref")); }); }); When I click the button it dosen't add the class to the anchor tags, so when I hover over them nothing changes. Any help here would be great.

  • Understanding "this" keyword

    - by Raffaele
    In this commit there is a change I cannot explain deferred.done.apply( deferred, arguments ).fail.apply( deferred, arguments ); becomes deferred.done( arguments ).fail( arguments ); AFAIK, when you invoke a function as a member of some object like obj.func(), inside the function this is bound to obj, so there would be no use invoking a function through apply() just to bound this to obj. Instead, according to the comments, this was required because of some preceding $.Callbacks.add implementation. My doubt is not about jQuery, but about the Javascript language itself: when you invoke a function like obj.func(), how can it be that inside func() the this keyword is not bound to obj?

  • switch easily between different main()

    - by lezebulon
    I'm using VS2010 I have a project with several headers and one file with the main() function. For testing purposes I'd like to be able to easily another main() function that would instanciate different things than my original main. Is there an easy way to define 2 "main" function, and easily switch between them? The best would be to compile 2 binaries, one that starts at main1() and the other at main2(), or it can be a solution that requires to recompile some files, it doesn't matter

  • GEvent.addListener(...) return?

    - by user354436
    Hello, my Question is as follows: What does GEvent.addListener(map, "click" function(){...}) return into the callback function? I don't find any information in the GMaps reference at all, can you show me some? The only thing I found out was that there are two parameters, "overlay" and "latLng" that are passed. The name of these parameters should not be of interest right? I could also name them "foo" and "bar" as far as I know. But the parameter "overlay" seems to be empty anyway? Also I have problems passing these two parameters directly into a callback function I created myself which looks like that... GEvent.addListener(gmap, "click", generateMarker(overlay, latLng)); ... instead of writing the following, which actually works fine. GEvent.addListener(gmap, "click", function(overlay, latLng) { generateMarker(overlay, latLng); });

  • getJSON and variable scope in javascript

    - by nillls
    Hi! In order to make function calls to our back-end php code we've implemented something called an ActionProxy like this: function ActionProxy(action, input, callback){ $.post("ActionProxy.php?method="+action, { data: input}, function(data, textStatus, XMLHttpRequest){ //return data.ResponseWhatever } }); The problem we're having is that using data outside the ActionProxy is impossible due to variable scope limitations (we assume), setting var res = data.ResponseWhatever or return data.ResponseWhatever is pretty futile. How would one handle these responses most appropriately so that functions calling the actionproxy can access the response values?

  • Replacing certain words with links to definitions using Javascript

    - by adharris
    I am trying to create a glossary system which will get a list of common words and their definitions via ajax, then replace any occurrence of that word in certain elements (those with the useGlossary class) with a link to the full definition and provide a short definition on mouse hover. The way I am doing it works, but for large pages it takes 30-40 seconds, during which the page hangs. I would like to either decrease the time it takes to do the replacement or make it so that the replacement is running in the background without hanging the page. I am using jquery for most of the javascript, and Qtip for the mouse hover. Here is my existing slow code: $(document).ready(function () { $.get("fetchGlossary.cfm", null, glossCallback, "json"); }); function glossCallback(data) { $(".useGlossary").each(function() { var $this = $(this); for (var i in data) { $this.html($this.html().replace(new RegExp("\\b" + data[i].term + "\\b", "gi"), function(m) {return makeLink(m, data[i].def);})); } $this.find("a.glossary").qtip({ style: { name: 'blue', tip: true } }) }); } function makeLink(m, def) { return "<a class='glossary glossary" + m.replace(/\s/gi, "").toUpperCase() + "' href='reference/glossary.cfm' title='" + def + "'>" + m + "</a>"; } Thanks for any feedback/suggestions!

  • I am using jquery ajax using text() but any html written in the XML doesn't render?

    - by Xtian
    So I have Jquery Ajax working real nice, but an issue I am having is in my XML if I want to bold a work or Italicize a sentence, if I do it in the XML using HTML tags it will not show up. I am pretty sure it is due to using the .text(). Any suggestions on a work around for this? $(document).ready(function(){ $.ajax({ type: "GET", url: "xml/sites.xml", dataType: "xml", success: function(xml) { $(xml).find('site').each(function(){ $(this).find('desc').each(function(){ var brief = $(this).find('brief').text(); var long = $(this).find('long').text(); var url = $(this).find('url').text(); $('<div class="brief"></div>').html(brief).appendTo('#link_'+id);

  • jQuery Sales Tax

    - by CKallemeres
    Hello everyone! I have created a function (see below) that calculates a 7.5% sales tax. Now I need help doing the following: Have totalTax() take in 2 arguments one for the price and one for the tax. On submit (use the onSubmit event handler to call this function) have the function process the price and the tax by manipulating the arguments you passed in. Have the sales tax on the page update dynamically with what ever the sales tax is that you defined for the function 7.5 percent sales tax: Instead of using .innerHTML use jQuery to access these document elements and write to them: document.getElementById('requestedAmount' ).innerHTML = priceInput; document.getElementById('requestedTax' ).innerHTML = salesTax; document.getElementById('requestedTotal' ).innerHTML = totalAmount; Original Code: <script type="text/javascript"> $().ready(function() { // validate the comment form when it is submitted $("#inputForm").validate(); $("#priceInput").priceFormat({ prefix: '', limit: 5, centsLimit: 2 }); }); function totalTax(){ var priceInput = document.getElementById( 'priceInput' ).value; var salesTax = Math.round(((priceInput / 100) * 7.5)*100)/100; var totalAmount = (priceInput*1) + (salesTax * 1); document.getElementById( 'requestedAmount' ).innerHTML = priceInput; document.getElementById( 'requestedTax' ).innerHTML = salesTax; document.getElementById( 'requestedTotal' ).innerHTML = totalAmount; } </script> <body> <form class="cmxform" id="inputForm" method="get" action=""> <p> <label for="priceInput">Enter the price: </label> <input id="priceInput" name="name" class="required"/> </p> <p> <input class="submit" type="submit" value="Submit" onclick="totalTax();"/> </p> </form> <div>Entered price: <p id="requestedAmount"></p> </div> <div>7.5 percent sales tax: <p id="requestedTax"></p> </div> <div>Total: <p id="requestedTotal"> </p> </div>

  • PHP Access property of a class from within a class instantiated in the original class.

    - by Iain
    I'm not certain how to explain this with the correct terms so maybe an example is the best method... $master = new MasterClass(); $master->doStuff(); class MasterClass { var $a; var $b; var $c; var $eventProccer; function MasterClass() { $this->a = 1; $this->eventProccer = new EventProcess(); } function printCurrent() { echo '<br>'.$this->a.'<br>'; } function doStuff() { $this->printCurrent(); $this->eventProccer->DoSomething(); $this->printCurrent(); } } class EventProcess { function EventProcess() {} function DoSomething() { // trying to access and change the parent class' a,b,c properties } } My problem is i'm not certain how to access the properties of the MasterClass from within the EventProcess-DoSomething() method? I would need to access, perform operations on and update the properties. The a,b,c properties will be quite large arrays and the DoSomething() method would be called many times during the execuction of the script. Any help or pointers would be much appreciated :)

  • Full and Partial Matching of Sets

    - by jeffrey
    I have several sets of the same type [Y, M, D] and am trying to write a function to search these sets and return an array of the available sets that fit my parameters. ReturnedSets = return_matches(Y,M,D); I want the three parameters of the function return_matches to be optional. Which means any combination of values can be used to return the sets. For example, one could write - return_matches(13,null,2); - and the function would look for all sets that contain [13, anyValue, 2]; I'm writing this in PHP, to allow users to manage dated files on my website, but I'd like to be able to use this function again for other uses. Thanks! edit: (This, or variations of this, is all I can come up with so far... There is something extra that I don't understand, because this function ends up / would not work to return sets that contain y and d, but leaving m arbitrary. if(y == s[0]){ if(m == s[1]){ if(d == s[2]){ print "day match"; } } else {print "month match";} } else {print "year match";} } else {print "no match";}

  • C++ - checking if a class has a certain method at compile time

    - by jetwolf
    Here's a question for the C++ gurus out there. Is there a way to check at compile time where a type has a certain method, and do one thing if it does, and another thing if it doesn't? Basically, I have a template function template <typename T> void function(T t); and I it to behave a certain way if T has a method g(), and another way if it doesn't. Perhaps there is something that can be used together with boost's enable_if? Something like this: template <typename T> enable_if<has_method<T, g, void ()>, void>::type function(T t) { // Superior implementation calling t.g() } template <typename T> disable_if<has_method<T, g, void ()>, void>::type function(T t) { // Inferior implementation in the case where T doesn't have a method g() } "has_method" would be something that preferably checks both that T has a method named 'g', and that the method has the correct signature (in this case, void ()). Any ideas?

  • What is the best way to inject a javascript script from another domain into a page? (without using a

    - by lowellk
    Here is a snippet of javascript for loading a script onto a given page asynchronously. I was wondering if there was anything wrong with it? Can it be improved? I haven't played with this yet, but some things I'm worried about are: - cross browser support - when script.readyState is true, will the old version of that function get clobbered? - can i always count on there being a head or body element? Here it is: function injectScript(url, callback){ var script = document.createElement('script'); script.type = "text/javascript"; script.setAttribute('async', 'true'); script.src = url; (document.getElementsByTagName('head')[0] || document.getElementsByTagName('body')[0]).appendChild(script); if (callback) { if (script.readyState){ script.onreadystatechange = function(){ if(script.readyState === "loaded" || script.readyState === "complete"){ script.onreadystatechange = null; callback(); } }; }else{ script.onload = function() { callback(); } } } }

  • Create and define Vector

    - by zdmytriv
    I'm looking for method to create Vector and push some values without defining variable Vector. For example: I have function: public function bla(data:Vector.<Object>):void { ... } this function expects Vector as parameter. I can pass parameters this way var newVector:Vector.<Object> = new Vector.<Object>(); newVector.push("bla1"); newVector.push("bla2"); bla(newVector); Can I do it in one line in Flex? I'm looking for something like: bla(new Vector.<Object>().push("bla1").push("bla2")); I've also tried this: bla(function():Vector.<Object> { var result:Vector.<Object> = new Vector.<Object>(2, true); result.push("bla1"); result.push("bla2"); return result; }); But it complains: 1067: Implicit coercion of a value of type Function to an unrelated type __AS3__.vec:Vector.<Object>...

  • C++ code generation for repeted task

    - by sateesh
    Hi, I have something like below which will get repeated many times based on the function that get called for e.g acceptfunction() { inserter["quantity"] = sdd.getfloat(quantity); inserter["prodtype"] = sdd.getstring(prodtype); : : so on } Like accept above there are 20 more functions(reject,cancel etc) which will do the similar thing.But the parameteres they insert can differ based on function called. How can I automate this kind of code.So that I dont need to write new function from scratch.Basically what I need is if i provide parametres like ("quantity",prodtype) through some text file or xml, it should generate the required function with the input parametres. Is this task can be handled through C++ tempalte Meta programming or someother code generation tool will help me to do this?
