  • Scope of This JavaScript Variable

    - by dkris
    I have a question and an issue wrt the code below: My question is what is the scope of the variable loaded here. The reason why i ask this is the onload="if(loaded==1)inittextarea() code is working fine on Firefox and not IE8. Why is this happening? Is there something specific i need to do here? Or is it not a valid practice? <html> <head> <title>Some Page</title> <link rel="stylesheet" href="../css/default.css" type="text/css"> <script type="text/javascript"> var loaded = 0; /*Point of interest*/ function jsLoaded() { loaded =1; } </script> <script type="text/javascript"> function inittextarea() { alert("test") tinyMCE.init({ elements : "content", theme : "advanced", readonly : true, mode : "exact", theme : "advanced", readonly : true, setup : function(ed) { ed.onInit.add(function() { tinyMCE.activeEditor.execCommand("mceToggleVisualAid"); }); } }); } </script> <script src="../js/tiny_mce/tiny_mce.js" onload="jsLoaded()" type="text/javascript"></script> </head> <body onload="if(loaded==1)inittextarea()"><!--Works on Firefox only--> *Usual stuff* </body></html> Any pointers please?

  • JavaScript: Very strange behavior with assigning methods in a loop

    - by Andrey
    Consider this code below: <a href="javascript:void(-1)" id="a1">a1</a> <a href="javascript:void(-1)" id="a2">a2</a> <script type="text/javascript"> var buttons = [] buttons.push("a1") buttons.push("a2") var actions = [] for (var i in buttons) { actions[buttons[i]] = function() { alert(i) } } var elements = document.getElementsByTagName("a") for (var k = 0; k < elements.length; k++) { elements[k].onclick = actions[elements[k].id] } </script> Basically, it shows two anchors, a1 and a2, and I expect to see "1" and "2" popping up in an alert when clicking on corresponding anchor. It doesn't happen, I get "2" when clicking on either. After spending an hour meditating on the code, I decided that it probably happens because dynamic onclick methods for both anchors keep the last value of "i". So I change that loop to for (var i in buttons) { var local_i = i.toString() actions[buttons[i]] = function() { alert(local_i) } } hoping that each dynamic function will get its own copy of "i" with immediate value. But after this change I get "1" popping up when I click on either link. What am I doing wrong? It's a huge show stopper for me.

    - by user1051505
    Hi I am trying to pass variables on the onclick event to a javascript function. I am trying the following way, I can't get the input value in the javascript function.(I am expecting an alert of 1.) Is it the right way of doing this? Please help. <head> <script> function submit_value(form) { alert(form.ip.value); } </script> </head> <table> <tr> <form> <td> <input id="ip" type="text" value="1"> </td> <td> <a href="javascript:;" onClick="submit_value(this)">Button</a> </td> </form> </tr> </table>

  • Javascript Noob Question. Need Help With Simple Script

    - by three3
    Hi everyone, I am new to JavaScript (only a couple of days of reading a book) and I am stuck on this code snippet. I have looked at it over and over again but cannot seem to figure out why it is not working. I am sure it is something really simple that I have just looked over but I really just need a fresh pair of eyes to look at this. The code is supposed to update a placeholder image on a page without the page having to reload. But when I am clicking on the link of an image, it is taking me to the link where the image is located instead of replacing the placeholder image. Here is my HTML code: <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"> <html xmlns="http://www.w3.org/1999/xhtml"> <head> <meta http-equiv="Content-Type" content="text/html; charset=UTF-8" /> <title>Image Gallery</title> <script type="text/javascript" src="scripts/showPic.js"></script> </head> <body> <h1>Snapshots</h1> <ul> <li> <a href="images/cat.jpg" onclick="showPic(this); return false;" title="A Cat">Cat</a> </li> <li> <a href="images/night.jpg" onclick="showPic(this); return false;" title="Night">Night</a> </li> <li> <a href="images/coke.jpg" onclick="showPic(this); return false;" title="Coke">Coke</a> </li> <li> <a href="images/sport.jpg" onclick="showPic(this); return false;" title="Sports">Sport</a> </li> <li> <a href="images/mnms.png" onclick="showPic(this); return false;" title="MnM's">MnM's</a> </li> <li> <a href="images/kid.jpg" onclick="showPic(this); return false;" title="A Kid">Kid</a> </li> </ul> <br /> <img id="placeholder" src="images/placeholder.jpg" alt="Place Holder Image" /> </body> </html> And here is the JavaScript function I am using to get this done: <script type="text/javascript"> function showPic(whichpic) { var source = whichpic.getAttribute("href"); var placeholder = document.getElementById("placeholder"); placeholder.setAttribute("src",source); } </script> Any help is greatly appreciated and thanks in advance for the help.

  • flash blocking javascript events

    - by jedierikb
    this is an edit of the original post now that I better understand the problem. now with source code! In IE, if body (or another html div has focus), then you keypress & click on flash at the same time, then release... a keyup event is never fired. It is not fired in javascript or in flash. Where is this keyup event? This is the order of event firing you get instead: javascriptKeyEvent:bodyDn ** currentFocuedElement: body javascriptKeyEvent:docDn ** currentFocuedElement: body actionScriptEvent::activate ** currentFocuedElement: [object] actionScriptEvent::mouseDown ** currentFocuedElement: [object] actionScriptEvent::mouseUp ** currentFocuedElement: [object] Subsequent keyup and keydown events are captured by flash, but that initial keyUp is never fired.. anywhere. And I need that keyup! Here is the html/javascript: <html> <head> <script type="text/javascript" src="p.js"></script> <script type="text/javascript" src="swfobject.js"></script> <script> function ic( evt ) { Event.observe( $("f1"), 'keyup', onKeyHandler.bindAsEventListener( this, "f1Up" ) ); Event.observe( $("f2"), 'keyup', onKeyHandler.bindAsEventListener( this, "f2Up" ) ); Event.observe( document, 'keyup', onKeyHandler.bindAsEventListener( this, "docUp" ) ); Event.observe( $("body"), 'keyup', onKeyHandler.bindAsEventListener( this, "bodyUp" ) ); Event.observe( window, 'keyup', onKeyHandler.bindAsEventListener( this, "windowUp" ) ); Event.observe( $("f1"), 'keydown', onKeyHandler.bindAsEventListener( this, "f1Dn" ) ); Event.observe( $("f2"), 'keydown', onKeyHandler.bindAsEventListener( this, "f2Dn" ) ); Event.observe( document, 'keydown', onKeyHandler.bindAsEventListener( this, "docDn" ) ); Event.observe( $("body"), 'keydown', onKeyHandler.bindAsEventListener( this, "bodyDn" ) ); Event.observe( window, 'keydown', onKeyHandler.bindAsEventListener( this, "windowDn" ) ); Event.observe( "clr", "mousedown", clearHandler.bindAsEventListener( this ) ); swfobject.embedSWF( "tmp.swf", "f2", "100%", "20px", "9.0.0.0", null, {}, {}, {} ); } function clearHandler( evt ) { clear( ); } function clear( ) { $("log").innerHTML = ""; } function onKeyHandler( evt, dn ) { logIt( "javascriptKeyEvent:"+dn ); } function AS2JS( wha ) { logIt( "actionScriptEvent::" + wha ); } function logIt( k ) { var id = document.activeElement; if (id.identify) { id = id.identify(); } $("log").innerHTML = k + " ** focuedElement: " + id + "<br>" + $("log").innerHTML; } Event.observe( window, 'load', ic.bindAsEventListener(this) ); </script> </head> <body id="body"> <div id="f1"><div id="f2" style="width:100%;height:20px; position:absolute; bottom:0px;"></div></div> <div id="clr" style="color:blue;">clear</div> <div id="log" style="overflow:auto;height:200px;width:500px;"></div> </body> </html> Here is the as3 code: package { import flash.display.Sprite; import flash.display.StageAlign; import flash.display.StageScaleMode; import flash.events.KeyboardEvent; import flash.events.MouseEvent; import flash.events.Event; import flash.external.ExternalInterface; public class tmpa extends Sprite { public function tmpa( ):void { extInt("flashInit"); stage.align = StageAlign.TOP_LEFT; stage.scaleMode = StageScaleMode.NO_SCALE; stage.addEventListener( KeyboardEvent.KEY_DOWN, keyDnCb, false, 0, true ); stage.addEventListener( KeyboardEvent.KEY_UP, keyUpCb, false, 0, true ); stage.addEventListener( MouseEvent.MOUSE_DOWN, mDownCb, false, 0, true ); stage.addEventListener( MouseEvent.MOUSE_UP, mUpCb, false, 0, true ); addEventListener( Event.ACTIVATE, activateCb, false, 0, true ); addEventListener( Event.DEACTIVATE, dectivateCb, false, 0, true ); } private function activateCb( evt:Event ):void { extInt("activate"); } private function dectivateCb( evt:Event ):void { extInt("deactivate"); } private function mDownCb( evt:MouseEvent ):void { extInt("mouseDown"); } private function mUpCb( evt:MouseEvent ):void { extInt("mouseUp"); } private function keyDnCb( evt:KeyboardEvent ):void { extInt( "keyDn" ); } private function keyUpCb( evt:KeyboardEvent ):void { extInt( "keyUp" ); } private function extInt( wha:String ):void { try { ExternalInterface.call( "AS2JS", wha ); } catch (ex:Error) { trace('ex: ' + ex); } } } }

  • Best server-side javascript servers.

    - by fmsf
    Hey, I've been wondering to try out server-side javascript for a while. And I'm finding a good amount of servers, like: Node.js Rhino SpiderMonkey among others. Could anyone with experience on server-side javascript, tell me which are the best engines? and why? I like the Node.js because it's based on Google's V8 engine. And seems easy to use. But some feedback on what you would choose would be great. Edit: Some benchmarks for Node. I'm thinking on going with this one but feedback is still welcome. Thanks

  • Ruby on Rails Mysterious Javascript Alert box with cookie information

    - by conorgil
    I have a problem in a Ruby on Rails app that I am working on. I have been working on the app for months and I have never had this problem before and after a bit of Google searches I think that somehow someone is trying to steal cookies with javascript. When I click on the link I get an alert box titled "the page at www.napkinboard.com says:" and contains the following message: __utmz=217223433.1270652009.59.3.utmcsr=localhost:3000|utmccn=(referral)|utmcmd=referral|utmcct=/; __utma=217223433.2133018314.1265749085.1271097412.1271125626.63; __utmc=217223433; __utmb=217223433.11.10.1271125626 I checked the database and all data associated with this 'food_item' looks completely normal and does not contain any javascript at all. How did this suddenly happen and how can I stop it? I appreciate any help. Thanks.

  • What is the `name` keyword in JavaScript?

    - by Joey Adams
    When I typed this apparently innocent snippet of code: values.name gedit highlighted name as a keyword. However, name is not listed by the pages linked to by an answer to a question about reserved keywords. I also did a couple trivial tests in SpiderMonkey, but name seemed to act like an ordinary identifier. A Google search didn't tell me much either. However, I did find a page listing name in "Other JavaScript Keywords". My guess is that name is a function or a member of some DOM element and does not intrude on the namespace. Is name really a keyword in JavaScript? If so, what does it do?

  • Hiding privates from Javascript Intellisense

    - by Robert Koritnik
    Is it possible to hide certain functions/fields from displaying in javascript intellisense drop down list in Visual Studio 2008? Either by javascript documentaion XML of by naming privates in a certain way? I've seen <private /> in jquery vsdoc file that implies exactly this behaviour, but doesn't meet my expectations { __hiddenField: 0, /// <private /> increment: function(){ /// <summary>Increments a private variable</summary> __hiddenField++; } } But since fields can't contain documentation (because they have no body) they have to be documented at the top. But still doesn't work: { /// <field name="__hiddenField" type="Number" private="true">PRIVATE USE</field> __hiddenField: 0, increment: function(){ /// <summary>Increments a private variable</summary> __hiddenField++; } } Impossible is a perfectly possible answer and will be accepted if you have the knowledge that it's actually not possible.

  • Dissapearing object function??

    - by WmasterJ
    Is there a reason for object functions to be unset or deleted or simply not applied for any reason at all that isn't intentional? I am maintaining someone elses code and gone through it many times. I use Google Chromes awesome debuger and also TextMate. These help me find the origin of error relatively fast. The problem I have now is that i have an object: types. This object conatains...types. And these types have functions and other variables attached to them. For some reason in the middle of the code, this type has been passed by reference millions of times probably. When it comes to a certain part of the code parts of it, seem to have dissapeared. Puff! And it's gone..! Anyone have a clue (other than it being removed somewhere else earlier in the code, I'm already looking for that)

  • Javascript timers

    - by resopollution
    I'm starting on a javascript MMORPG that will actually work smoothly. Currently, I created a demo to prove that I can move characters around and have them chat with each other, as well as see eachother move around live. http://set.rentfox.net/ Now Javascript timers are something I have not used extensively, but from what I know, correct me if I'm wrong, is that having multiple setIntervals happening at the same time doesn't really work well b/c it's all on a single thread. Lets say I wanted to have 10 different people nuking fireballs at a monster by using sprite background positioning with setInterval -- that animation would require 10 setIntervals doing repainting of the DOM for sprite background-position shifts. Wouldn't that be a big buggy? I was wondering if there was a way around all this, perhaps using Canvas, so that animations can all happen concurrently without creating an event queue and I don't have to worry about timers. Hope that makes sense, and please let me know if I need to clarify further.

  • Which JavaScript MVC framework to use for wysiwyg editing and floating context-sensitive settings pa

    - by ernests
    I'm developing a cms that allows editing everything on the page (generated server-side with a template engine) by just clicking on it — the area turns into input field, textarea or a full-featured tinyMCE editor, Template defines editable elements like "page heading", "copyright footer text", "image", "rich text block" etc. Along with that there's always a flotaing panel with several tabs, some of which contain general settings like page bacground color, font settings etc, but some are context sensitive (e.g., the clicking on "image" editable field triggers to display uploading/cropping/captioning interface in the floating panel). All settings in the panel are either simple inputs or sliders or checkboxes. I'm new to using MVC with javascript, and in fact haven't used it much before. jQuery is used as code library for the project. Should i use JavascriptMVC, SproutCore or anything else? Does any of them allow some kind of sandboxing (within bounds of commmon sense) to allow some javascript code by user-generated skins on my cms? thank you!

  • Why wont this JS code work if its all on the same line?

    - by culov
    I'm writing HTML code for a java servlet. i first write the code in html/js so i can debug what im working on, and then ill make it a java string and put it in my servlet. My problem is that the code is working fine when i view it in ff from a local html file, but when i view it on my java servlet, it doesnt work because the js isnt getting called. what I did was format the html that my servlet generated so that its not all on a single line and ran the code again. This time it worked. I copied this working code into a browser address bar so that it will all be on a single line, and copied that code back into the script in my html file. Now, when the previously working code is on a single line, it doesnt work. Here's the formatted JS: var sMax var holder; var preSet; var rated; var request; function rating(num){ sMax = 0; for(n=0; n<num.parentNode.childNodes.length; n++){ if(num.parentNode.childNodes[n].nodeName == "A"){ sMax++; } } if(!rated){ s = num.id.replace("_", ''); a = 0; for(i=1; i<=sMax; i++){ if(i<=s){ document.getElementById("_"+i).className = "on"; document.getElementById("rateStatus").innerHTML = num.title; holder = a+1; a++; }else{ document.getElementById("_"+i).className = ""; } } } } function off(me){ if(!rated){ if(!preSet){ for(i=1; i<=sMax; i++){ document.getElementById("_"+i).className = ""; document.getElementById("rateStatus").innerHTML = me.parentNode.title; } }else{ rating(preSet); document.getElementById("rateStatus").innerHTML = document.getElementById("ratingSaved").innerHTML; } } } function rateIt(me){ if(!rated){ document.getElementById("rateStatus").innerHTML = document.getElementById("ratingSaved").innerHTML + " "+me.title; preSet = me; rated=1; sendRate(me); rating(me); } } function sendRate(sel){ alert("Your rating was: "+sel.title); addRating("rating", "?truck=kogibbq?rating="+ sel.id); } function addRating(servletName, servletArguments){ var servlet = servletName; var arg = servletArguments var req = servlet + arg; alert(req); addrequest(req); request.onreadystatechange = function(){ alert("response received"); } } function addrequest(req) { try { request = new XMLHttpRequest(); }catch (e) { try { request = new ActiveXObject("Microsoft.XMLHTTP"); }catch (e) { alert("XMLHttpRequest error: " + e); } } request.open("GET", element, true); request.send(null); return request; } Thanks.

  • Javascript debugging: stopping/breaking at every javascript invocation

    - by portoalet
    I am dealing with a complex legacy javascript code base, and it's difficult to figure out where to put breakpoint (I have to find the files, put a breakpoint in firebug etc). Is there a way so that Firebug breaks on the first javascript execution that it encounters every time? In other words, every time I click on something on the page, and if a javascript code is executed, I want Firebug to break on that line? Of course I don't want Firebug to stop when it executes it's internal javascript. Is this possible?

  • Attaching events in JavaScript

    - by R0MANARMY
    As comment to one of the questions here a commenter wrote (emphasis mine): ... By using an inline "onclick" you are doing a similar thing, but it is harder to maintain and more prone to issues. The JavaScript community as a whole has been moving away from inline JavaScript for a while now. This was referring to attaching events to HTML elements using $("#someID").click(function(){ do something here...; }); rather than <a id="someID" onclick="someFunction();"> Has there really been a shift away from the old school way of declaring events inline, and if so, what are the benefits of one of the other?
