  • onPageLoad is not working properly in Firefox Extension Development

    - by Tharaka Deshan
    I am new to Firefox Extension Development and doing my 1st program. Simply I needed to pop up a alert once it loaded the page. My code was like this: var myExtension = { init: function() { if(gBrowser) gBrowser.addEventListener("DOMContentLoaded", this.onPageLoad, false); }, onPageLoad: function(aEvent) { alert("Loaded"); } } window.addEventListener("load", function load(event){ window.removeEventListener("load", load, false); myExtension.init(); },false); But I am getting the alert box for couple of times. Then I found about "#document" and then I added a IF condition: onPageLoad: function(aEvent) { if (aEvent.originalTarget.nodeName == '#document') { alert("Loaded"); } } Unfortunately still I am getting the same. Please advise me on this.

  • JavaScript OnClick Handler Not Invoking

    - by potatolicious
    I'm calling a javascript function in an inline onclick like so: <a href="#" onclick="removeAttribute('foo', 'bar');">Some Link</a> When I click on the link, though, nothing happens. I have other links (to other functions) tied to onclicks that work fine elsewhere on the same page. All links to this "removeAttribute" function fail. There are no errors in Firebug, and the onclick event handler is being invoked - but stepping into the removeAttribute function ends up, for some reason, somewhere in jQuery.js. At no point does removeAttribute ever get called. If I do: javascript:removeAttribute('foo', 'bar'); in Firefox's address bar. The function is called successfully. Anyone seen this?

  • dojo.connect won't connect 'onclick' with button

    - by Daniel
    I'm running into a problem using dojo.connect() to connect an 'onclick' event with this button: <button dojoType="dijit.form.Button" widgetId="inbox_button" id="inbox_button">Inbox</button> and the code making the connection is: var inbox_button=dojo.byId("inbox_button"); dojo.connect(inbox_button,'onclick',function(){ var container=dijit.byId("center"); container.addChild(new dijit.layout.ContentPane({region: "left", content: "...", style: "width: 100px;"})) }); However, instead of executing the function when the button is clicked, ANY onclick event triggers the function, and I end up with a lot of children containers. Even though I'm pretty certain the .connect() function should be available as part of dojo's base functionality, I've 'required' it explicitly: dojo.require("dojo._base.connect"); Any ideas as to why this might be happening?

  • JavaScript: How to create a new instance of a class without using the new keyword?

    - by Alessandro Vernet
    I think the following code will make the question clear. // My class var Class = function() { console.log("Constructor"); }; Class.prototype = { method: function() { console.log("Method");} } // Creating an instance with new var object1 = new Class(); object1.method(); console.log("New returned", object1); // How to write a factory which can't use the new keyword? function factory(clazz) { // Assume this function can't see "Class", but only sees its parameter "clazz". return clazz.call(); // Calls the constructor, but no new object is created return clazz.new(); // Doesn't work because there is new() method }; var object2 = factory(Class); object2.method(); console.log("Factory returned", object2);

  • Encrypt temporary password using public ssh key

    - by David M. Syzdek
    I manage a virtual office and our staff uses both SSH keys and passwords for authentication. If one of our staff forgets his password, is there a way to encrypt a temporary password using his public RSA ssh key so I can send it to him via e-mail? I've seen other questions related to this one, however the "answers" generally recommend against using the public/private SSH keys to perform general encryption/decryption and do not actually state if this is possible. I would like to know if it is indeed possible and what are the steps to encrypt and then decrypt the password.

  • Lifetime of javacript variables.

    - by The Machine
    What is the lifetime of a variable in javascript, declared with "var". I am sure, it is definitely not according to expectation. <script> function(){ var a; var fun=function(){ // a is accessed and modified } }(); </script> Here how and when does javascript garbage collect the variable a? Since 'a' is a part of the closure of the inner function, it ideally should never get garbage collected, since the inner function 'fun', may be passed as a reference to an external context.So 'fun' should still be able to access 'a', from the external context. If my understanding is correct, how does garbage collection happen then, and how does it ensure to have enough memory space, since keeping all variables in memory until the execution of the program might not be tenable ?

  • Making all variables accessible to namespace

    - by Gökhan Sever
    Hello, Say I have a simple function: def myfunc(): a = 4.2 b = 5.5 ... many similar variables ... I use this function one time only and I am wondering what is the easiest way to make all the variables inside the function accessible to my main name-space. Do I have to declare global for each item? or any other suggested methods? Thanks.

  • How to process events chain.

    - by theblackcascade
    I need to process this chain using one LoadXML method and one urlLoader object: ResourceLoader.Instance.LoadXML("Config.xml"); ResourceLoader.Instance.LoadXML("GraphicsSet.xml"); Loader starts loading after first frameFunc iteration (why?) I want it to start immediatly.(optional) And it starts loading only "GraphicsSet.xml" Loader class LoadXml method: public function LoadXML(URL:String):XML { urlLoader.addEventListener(Event.COMPLETE,XmlLoadCompleteListener); urlLoader.load(new URLRequest(URL)); return xml; } private function XmlLoadCompleteListener(e:Event):void { var xml:XML = new XML(e.target.data); trace(xml); trace(xml.name()); if(xml.name() == "Config") XMLParser.Instance.GameSetup(xml); else if(xml.name() == "GraphicsSet") XMLParser.Instance.GraphicsPoolSetup(xml); } Here is main: public function Main() { Mouse.hide(); this.addChild(Game.Instance); this.addEventListener(Event.ENTER_FRAME,Game.Instance.Loop); } And on adding a Game.Instance to the rendering queue in game constuctor i start initialize method: public function Game():void { trace("Constructor"); if(_instance) throw new Error("Use Instance Field"); Initialize(); } its code is: private function Initialize():void { trace("initialization"); ResourceLoader.Instance.LoadXML("Config.xml"); ResourceLoader.Instance.LoadXML("GraphicsSet.xml"); } Thanks.

  • How to create 2 different scripts for 2 browsers (IE+all the rest)

    - by Barnabas Nagy
    I'm trying to solve an IE CSS issue by using conditional tags. My jQuery that does the job of tabbed box effect calls an id that is inside the conditional tags. I've given new ids to IE so on IE the jQuery is not working. I tried to duplicate the script with the new id in one of the script but the 2 scripts seems to get in conflict. My jQuery (in between the head tags) is (for all all browsers except IE): <script> var currentTab = 0; // Set to a different number to start on a different tab. function openTab(clickedTab) { var thisTab = $(".tabbed-box .tabs a").index(clickedTab); $(".tabbed-box .tabs li a").removeClass("active"); $(".tabbed-box .tabs li a:eq("+thisTab+")").addClass("active"); $(".tabbed-box .tabbed-content").hide(); $(".tabbed-box .tabbed-content:eq("+thisTab+")").show(); currentTab = thisTab; } $(document).ready(function() { $(".tabs li:eq(0) a").css("border-left", "none"); $(".tabbed-box .tabs li a").click(function() { openTab($(this)); return false; }); $(".tabbed-box .tabs li a:eq("+currentTab+")").click() }); </script> And I would need this for IE: <script> var currentTab = 0; // Set to a different number to start on a different tab. function openTab(clickedTab) { var thisTab = $(".tabbed-box .tabs a").index(clickedTab); $(".tabbed-box ie-.tabs li a").removeClass("active"); $(".tabbed-box ie-.tabs li a:eq("+thisTab+")").addClass("active"); $(".tabbed-box .tabbed-content").hide(); $(".tabbed-box .tabbed-content:eq("+thisTab+")").show(); currentTab = thisTab; } $(document).ready(function() { $(".ie-tabs li:eq(0) a").css("border-left", "none"); $(".tabbed-box .ie-tabs li a").click(function() { openTab($(this)); return false; }); $(".tabbed-box .ie-tabs li a:eq("+currentTab+")").click() }); </script> Having the 2 scripts in the head conflicts with each other. Maybe there is a way to combine them?

  • Event type property lost in IE-8

    - by Channel72
    I've noticed a strange Javascript error which only seems to happen on Internet Explorer 8. Basically, on IE-8 if you have an event handler function which captures the event object in a closure, the event "type" property seems to become invalidated from within the closure. Here's a simple code snippet which reproduces the error: <html> <head> <script type = "text/javascript"> function handleClickEvent(ev) { ev = (ev || window.event); alert(ev.type); window.setTimeout(function() { alert(ev.type); // Causes error on IE-8 }, 20); } function foo() { var query = document.getElementById("query"); query.onclick = handleClickEvent; } </script> </head> <body> <input id = "query" type = "submit"> <script type = "text/javascript"> foo(); </script> </body> </html> So basically, what happens here is that within the handleClickEvent function, we have the event object ev. We call alert(ev.type) and we see the event type is "click". So far, so good. But then when we capture the event object in a closure, and then call alert(ev.type) again from within the closure, now all of a sudden Internet Explorer 8 errors, saying "Member not found" because of the expression ev.type. It seems as though the type property of the event object is mysteriously gone after we capture the event object in a closure. I tested this code snippet on Firefox, Safari and Chrome, and none of them report an error condition. But in IE-8, the event object seems to become somehow invalidated after it's captured in the closure. Question: Why is this happening in IE-8, and is there any workaround?

  • jQuery class adding and removing with click and mouseleave

    - by danixd
    I just want to control a div by toggling a class on click, as well as removing it when the mouse leaves the div. I had it working with mouseout, but when I entered over a child element, the mouseOut triggered, so I know I need to use mouseleave. I am just unsure how incorporate telling jQuery the mouse has entered. Yes I am new to this! Here is my code: $(function(){ $('.main').click(function() { $(this).toggleClass('activated'); }); }); $(function(){ $('.main').mouseleave(function() { $(this).removeClass('activated'); }); });

  • Temporary Onmouseover

    - by 2x2p1p
    Hi guys :) Css "over" selector applys a temporary style to an element, it isn't definitive: div:hover { background-color: red; } I can use the same thing with javascript but it is a bit complicate and impossible for several elements: var elem = document.getElementByTagName ("div")[0]; elem.onmouseover = function () { this.style.backgroundColor = "red"; } elem.onmouseout = function () { this.style.backgroundColor = "transparent"; } There is a better way ? Something like this: document.getElementByTagName ("div")[0].ontemporarymouseover = function () { // LoL this.style.backgroundColor = "red"; } Thanks

  • Overriding RPM public key database

    - by pilcrow
    Can rpm be persuaded to import and fetch public keys from an arbitrary pubkey database? On the same build machine I've got two automated users who each need to verify package signatures from different sources, signed under different keys. If I rpm --import pkg-source1.pub pkg-source2.pub, each user will be able to verify packages intended for the other. I'd rather each user not know about the other's public keyring. Is there a way I can specify an alternate or supplementary pubkey database on a per-user or per-rpm(8)-invocation basis?

  • Can I find out the return value before returning while debugging in Visual Studio

    - by doekman
    Take the following function: DataTable go() { return someTableAdapter.getSomeData(); } When I set a breakpoint in this function, is there a possibility to inspect the returned value? The "go" function is directly coupled to a datagrid in an aspx page. The only way to inspect the returned datatable, is to use a temporary variable... However, that's a bit inconvenient. Isn't there another way?

  • Display data requested by an ajax.load() call once complete, not during the call.

    - by niczoom
    My jQuery code (using ajax) request's data from a php script (pgiproxy.php) using the following function: function grabPage($pageURL) { $homepage = file_get_contents($pageURL); echo $homepage; } I then extract the html code i need from the returned data using jQuery and insert it into a div called #BFX, as follows: $("#btnNewLoadMethod1").click(function(){ $('#temp1').load('pgiproxy.php', { data : $("#formdata").serialize(), mode : "graph"} , function() { $('#temp').html( $('#temp1').find('center').html() ); $('#BFX').html( $('#temp').html() ); }); }); This works fine. I get the html data (which is a gif image) i need displayed on screen in the correct div. The problem is i can see the html data loading into the div (dependant on network speed), but what I want is to insert the extracted html code into #BFX ONLY when the ajax request has fully completed.

  • Threading and pcap issues.

    - by cftmon
    I have a GUI program that allows a user a scan a network, the issue is that when the pcap_loop function is called, my GUI program becomes unresponsive.(the pcap_loop blocks the current thread). When i try to use pthreads, i got a SIGSEGV fault at the pcap_loop function.Why?It's as if the thread can't see the procPacket function itself. void procPacket(u_char *arg, const struct pcap_pkthdr *pkthdr, const u_char *packet) { //show packets here } void* pcapLooper(void* param) { pcap_t* handler = (pcap_t*) param; pcap_loop(handler, 900 ,procPacket, NULL ); } //some function that runs when a button is pressed //handler has been opened through pcap_open_live pthread_t scanner; int t = pthread_create(&scanner,NULL,&pcapLooper, &handler ); if(t) { std::cout << "failed" << std::endl; } pthread_join(scanner,NULL); //do other stuff.

  • Why do I see MS jQuery samples use `$(domReady); `?

    - by Atomiton
    I don't know if anyone ELSE has noticed this, but I noticed the jQuery samples I see on MS tend to use a different format: <script type="text/javascript"> $( domReady ); function domReady() { $('#btn').click( showMessage ); } function showMessage() { $('#message').fadeIn('slow'); } </script> Isn't this the same as: $(document).ready( function() { $('#btn').click( showMessage ); function showMessage() { $('#message').fadeIn('slow'); } }); Is there any advantage of using one syntax over the other? I will admit, the MS way does look cleaner.

  • How to use keyword this in a mouse wrapper in right context in Javascript?

    - by MartyIX
    Hi, I'm trying to write a simple wrapper for mouse behaviour. This is my current code: function MouseWrapper() { this.mouseDown = 0; this.OnMouseDownEvent = null; this.OnMouseUpEvent = null; document.body.onmousedown = this.OnMouseDown; document.body.onmouseup = this.OnMouseUp; } MouseWrapper.prototype.Subscribe = function (eventName, fn) { // Subscribe a function to the event if (eventName == 'MouseDown') { this.OnMouseDownEvent = fn; } else if (eventName == 'MouseUp') { this.OnMouseUpEvent = fn; } else { alert('Subscribe: Unknown event.'); } } MouseWrapper.prototype.OnMouseDown = function () { this.mouseDown = 1; // Fire event $.dump(this.OnMouseDownEvent); if (this.OnMouseDownEvent != null) { alert('test'); this.OnMouseDownEvent(); } } MouseWrapper.prototype.OnMouseUp = function () { this.mouseDown = 0; // Fire event if (this.OnMouseUpEvent != null) { this.OnMouseUpEvent(); } } From what I gathered it seems that in MouseWrapper.prototype.OnMouseUp and MouseWrapper.prototype.OnMouseDown the keyword "this" doesn't mean current instance of MouseWrapper but something else. And it makes sense that it doesn't point to my instance but how to solve the problem? I want to solve the problem properly I don't want to use something dirty. My thinking: * use a singleton pattern (mouse is only one after all) * pass somehow my instance to OnMouseDown/Up - how? Thank you for help!

  • Creating Dynamic variables from json response

    - by c0mrade
    My JSON response looks like this : {"sample":[{"id":"2","name":"branch name"},{"id":"3","name":"branch name 2"}]} My function looks like this : function getJSONObjects(){ $.getJSON("http://localhost/api/branches", function(data){ $.each(data.sample, function(i,item){ var loc = "branch"; eval("var " + loc + item.id + "=123;"); alert(loc + item.id); }); }); } The idea is to create branch + id object so I can do something with it(create marker on a map), so I tried to assign it any value to see if this was working. I wanted both branch2 and branch3 to alert 123 so I have something to start with. But currently this alerts branch2 and branch3 instead of 123. I have little experience with creating dynamic variables/objects can someone tell me what I'm doing wrong or maybe another approach towards solving this?

  • jQuery timer, ajax, and "nice time"

    - by Mil
    So for this is what I've got: $(document).ready(function () { $("#div p").load("/update/temp.php"); function addOne() { var number = parseInt($("#div p").html()); return number + 1; } setInterval(function () { $("#div p").text(addOne()); }, 1000); setInterval(function () { $("#geupdate p").load("/update/temp.php");} ,10000); }); So this grabs a a UNIX timestamp from temp.php and puts into into #div p, and then adds 1 to it every second, and then every 10 seconds it will check the original file to keep it up to speed. My problem is that I need to format this UNIX timestamp into a format such as "1 day 3 hours 56 minutes and 3 seconds ago", while also doing all the incrementation and ajax calls. I'm not very experienced with jquery/javascript, so I might be missing something basic.

  • Retreive value stored in array with jquery index

    - by Dustin
    I am trying to retreive the stored value (div id) of an index stored in var "current" when it's div is clicked, so I can use it in a function to iterate through to the next index later. I want to store this stored value in a var so I can use it in a div show/hide function. my html is quite simple: <div class="gallerypreview" id="1"></div> <div class="gallerypreview" id="2"></div> <div class="gallerypreview" id="3"></div> my javascript is something like this: var images = new Array(); $(document).ready( function(){ $('.gallerypreview').each(function() { images.push($(this).attr("id")); }); $('.gallerypreview').click(function() { var current = $('.gallerypreview').index(this); }); }); how would I go about retrieving the div id from this clicked div? nothing I have tried has worked. I can get the index # fine, but I cannot find the value of the index using any functions that utilize the index # yet.
