  • Attach my sprite with Box2d

    - by user919496
    I'm coding Javascript(HTML5) with Box2D. And I want to ask how to attach Sprite with Box2D. This is function My sprite: function My_Sprite() { this.m_Image = new Image(); this.m_Position = new Vector2D(0,0); this.m_CurFrame = 0; this.m_ColFrame = 0; this.m_Size = new Vector2D(0,0); this.m_Scale = new Vector2D(0,0); this.m_Rotation = 0; } My_Sprite.prototype.constructor = function (_Image_SRC) { this.m_Image.src = _Image_SRC; } My_Sprite.prototype.constructor = function (_Image_SRC,_Size,_Col) { this.m_Image.src = _Image_SRC; this.m_Size = _Size; this.m_ColFrame = _Col; this.m_Scale = new Vector2D(1, 1); } My_Sprite.prototype.Draw = function (context) { context.drawImage(this.m_Image, this.m_Size.X * (this.m_CurFrame % this.m_ColFrame), this.m_Size.Y * parseInt(this.m_CurFrame / this.m_ColFrame), this.m_Size.X, this.m_Size.Y, this.m_Position.X, this.m_Position.Y, this.m_Size.X * this.m_Scale.X, this.m_Size.Y * this.m_Scale.Y ); } and this is function Object : function Circle(type, angle, size) { // Circle.prototype = new My_Object(); // Circle.prototype.constructor = Circle; // Circle.prototype.parent = My_Object.prototype; this.m_den = 1.0; this.m_fri = 0.5; this.m_res = 0.2; fixDef.density = this.m_den; fixDef.friction = this.m_fri; fixDef.restitution = this.m_res; fixDef.shape = new b2PolygonShape; bodyDef.type = type; bodyDef.angle = angle; bodyDef.userData = m_spriteCircle; fixDef.shape = new b2CircleShape( Radius / SCALE //radius ); this.m_Body = world.CreateBody(bodyDef); this.m_Body.CreateFixture(fixDef); m_spriteCircle = new My_Sprite(); this.Init(); } Circle.prototype.Init = function () { m_spriteCircle.constructor("images/circle.png", new Vector2D(80, 80), 1); m_spriteCircle.m_CurFrame = 0; } Circle.prototype.Draw = function (context) { m_spriteCircle.Draw(context); } and I draw it : var m_Circle = new Circle(); m_Circle.Draw(context);

  • Bouncing off a circular Boundary with multiple balls?

    - by Anarkie
    I am making a game like this : Yellow Smiley has to escape from red smileys, when yellow smiley hits the boundary game is over, when red smileys hit the boundary they should bounce back with the same angle they came, like shown below: Every 10 seconds a new red smiley comes in the big circle, when red smiley hits yellow, game is over, speed and starting angle of red smileys should be random. I control the yellow smiley with arrow keys. The biggest problem I have reflecting the red smileys from the boundary with the angle they came. I don't know how I can give a starting angle to a red smiley and bouncing it with the angle it came. I would be glad for any tips! My js source code : var canvas = document.getElementById("mycanvas"); var ctx = canvas.getContext("2d"); // Object containing some global Smiley properties. var SmileyApp = { radius: 15, xspeed: 0, yspeed: 0, xpos:200, // x-position of smiley ypos: 200 // y-position of smiley }; var SmileyRed = { radius: 15, xspeed: 0, yspeed: 0, xpos:350, // x-position of smiley ypos: 65 // y-position of smiley }; var SmileyReds = new Array(); for (var i=0; i<5; i++){ SmileyReds[i] = { radius: 15, xspeed: 0, yspeed: 0, xpos:350, // x-position of smiley ypos: 67 // y-position of smiley }; SmileyReds[i].xspeed = Math.floor((Math.random()*50)+1); SmileyReds[i].yspeed = Math.floor((Math.random()*50)+1); } function drawBigCircle() { var centerX = canvas.width / 2; var centerY = canvas.height / 2; var radiusBig = 300; ctx.beginPath(); ctx.arc(centerX, centerY, radiusBig, 0, 2 * Math.PI, false); // context.fillStyle = 'green'; // context.fill(); ctx.lineWidth = 5; // context.strokeStyle = '#003300'; // green ctx.stroke(); } function lineDistance( positionx, positiony ) { var xs = 0; var ys = 0; xs = positionx - 350; xs = xs * xs; ys = positiony - 350; ys = ys * ys; return Math.sqrt( xs + ys ); } function drawSmiley(x,y,r) { // outer border ctx.lineWidth = 3; ctx.beginPath(); ctx.arc(x,y,r, 0, 2*Math.PI); //red ctx.fillStyle="rgba(255,0,0, 0.5)"; ctx.fillStyle="rgba(255,255,0, 0.5)"; ctx.fill(); ctx.stroke(); // mouth ctx.beginPath(); ctx.moveTo(x+0.7*r, y); ctx.arc(x,y,0.7*r, 0, Math.PI, false); // eyes var reye = r/10; var f = 0.4; ctx.moveTo(x+f*r, y-f*r); ctx.arc(x+f*r-reye, y-f*r, reye, 0, 2*Math.PI); ctx.moveTo(x-f*r, y-f*r); ctx.arc(x-f*r+reye, y-f*r, reye, -Math.PI, Math.PI); // nose ctx.moveTo(x,y); ctx.lineTo(x, y-r/2); ctx.lineWidth = 1; ctx.stroke(); } function drawSmileyRed(x,y,r) { // outer border ctx.lineWidth = 3; ctx.beginPath(); ctx.arc(x,y,r, 0, 2*Math.PI); //red ctx.fillStyle="rgba(255,0,0, 0.5)"; //yellow ctx.fillStyle="rgba(255,255,0, 0.5)"; ctx.fill(); ctx.stroke(); // mouth ctx.beginPath(); ctx.moveTo(x+0.4*r, y+10); ctx.arc(x,y+10,0.4*r, 0, Math.PI, true); // eyes var reye = r/10; var f = 0.4; ctx.moveTo(x+f*r, y-f*r); ctx.arc(x+f*r-reye, y-f*r, reye, 0, 2*Math.PI); ctx.moveTo(x-f*r, y-f*r); ctx.arc(x-f*r+reye, y-f*r, reye, -Math.PI, Math.PI); // nose ctx.moveTo(x,y); ctx.lineTo(x, y-r/2); ctx.lineWidth = 1; ctx.stroke(); } // --- Animation of smiley moving with constant speed and bounce back at edges of canvas --- var tprev = 0; // this is used to calculate the time step between two successive calls of run function run(t) { requestAnimationFrame(run); if (t === undefined) { t=0; } var h = t - tprev; // time step tprev = t; SmileyApp.xpos += SmileyApp.xspeed * h/1000; // update position according to constant speed SmileyApp.ypos += SmileyApp.yspeed * h/1000; // update position according to constant speed for (var i=0; i<SmileyReds.length; i++){ SmileyReds[i].xpos += SmileyReds[i].xspeed * h/1000; // update position according to constant speed SmileyReds[i].ypos += SmileyReds[i].yspeed * h/1000; // update position according to constant speed } // change speed direction if smiley hits canvas edges if (lineDistance(SmileyApp.xpos, SmileyApp.ypos) + SmileyApp.radius > 300) { alert("Game Over"); } // redraw smiley at new position ctx.clearRect(0,0,canvas.height, canvas.width); drawBigCircle(); drawSmiley(SmileyApp.xpos, SmileyApp.ypos, SmileyApp.radius); for (var i=0; i<SmileyReds.length; i++){ drawSmileyRed(SmileyReds[i].xpos, SmileyReds[i].ypos, SmileyReds[i].radius); } } // uncomment these two lines to get every going // SmileyApp.speed = 100; run(); // --- Control smiley motion with left/right arrow keys function arrowkeyCB(event) { event.preventDefault(); if (event.keyCode === 37) { // left arrow SmileyApp.xspeed = -100; SmileyApp.yspeed = 0; } else if (event.keyCode === 39) { // right arrow SmileyApp.xspeed = 100; SmileyApp.yspeed = 0; } else if (event.keyCode === 38) { // up arrow SmileyApp.yspeed = -100; SmileyApp.xspeed = 0; } else if (event.keyCode === 40) { // right arrow SmileyApp.yspeed = 100; SmileyApp.xspeed = 0; } } document.addEventListener('keydown', arrowkeyCB, true); JSFiddle : http://jsfiddle.net/gj4Q7/

  • Combining mousedown and mousemove events together with Javascript (JQUERY?)

    - by webzide
    Dear experts, I would like to combine a the mousedown and mousemove and mouseup events together. Basically the application of this would be making a UI for selecting elements. Like selecting icons in windows when the mouse is clicked down and as you move it, a dotted border dynamically moves with it. I know this is possible with the predefined UI of Jquery. But I am building a web application that requires the integration of this and would like to know the technique. I spend hours on this and it just doesn't work. here's is the code i have so far and the logic behind it: $(document).bind('mousedown', function (evt) { evt = (evt) ? evt : event; startX = evt.clientX; startY = evt.clientY; div = document.createElement("div"); div.style.position = "absolute"; div.style.left = startX + "px"; div.style.top = startY + "px"; div.style.border = "1px dotted #DDDDDD"; $(document).bind('mousemove', function(evt){ evt=(evt) ? evt: event; alert("TESTING OF THIS WORKS"); }); }); $(document).bind('mouseup',function(evt) { var evt = (evt) ? evt : event; var endX = evt.clientX; var endY = evt.clientY; difX = (endX - startX); difY = (endY - startY) if ((difX || difY) > 0) { div.style.width = difX + "px"; div.style.height = difY + "px"; document.body.appendChild(div); } $(this).unbind('mousemove'); }); As you can see I have placed an event binding of mousemove into the event function of mousedown so that it can only be invoked when the mouse is down. but the problem is, once that event is binded, it does not come off. The borders does not move dynamically as expected. Maybe my logic is entirely messed up. If anyone could point me the the right direction that would be great. THanks in advance.

  • nSticky/static variable references in for loops

    - by pthulin
    In this example I create three buttons 'one' 'two' 'three'. When clicked I want them to alert their number: <html> <head> <script type="application/javascript" src="jquery.js"></script> <script type="application/javascript"> $(document).ready(function() { var numbers = ['one', 'two', 'three']; for (i in numbers) { var nr = numbers[i]; var li = $('<li>' + nr + '</li>'); li.click(function() { var newVariable = String(nr); alert(i); // 2 alert(nr); // three alert(newVariable); // three alert(li.html()); // three }); $('ul').append(li); } }); </script> </head> <body> <ul> </ul> </body> </html> The problem is, when any of these are clicked, the last value of the loop's variables is used, i.e. alert box always says 'three'. In JavaScript, variables inside for-loops seem to be 'static' in the C language sense. Is there some way to create separate variables for each click function, i.e. not using the same reference? Thanks! Edit: The solution is to use jQuery.data to associate arbitrary data with each element: <html> <head> <script type="application/javascript" src="jquery.js"></script> <script type="application/javascript"> $(document).ready(function() { var numbers = ['one', 'two', 'three']; for (i in numbers) { var nr = numbers[i]; var li = $('<li>' + nr + '</li>'); li.data('nr', nr); li.click(function() { alert($(this).data('nr')); }); $('ul').append(li); } }); </script> </head> <body> <ul> </ul> </body> </html>

  • Javascript data parsing in IE vs other browsers... It seems kinda screwed up. What's the deal?

    - by Carter
    Firstly, when I say other browsers I really only mean Firefox because that's all I tested in. Internet Explorer can parse a date followed by a single character as a proper date. Whereas Firefox behaves as I'd expect. For example... var dateString = new Date("1/1/2010f"); alert(dateString); In IE it will alert... Thu Dec 31 21:00:00 UTC-0900 2009 Whereas in FF is will spit out... "Invalid Date" I first noticed this using the jquery validation plug in. http://docs.jquery.com/Plugins/Validation/Methods/date It seems like it just subtracts some amount of hours off the actual date in IE when a character is appended. I've tested in IE6 and IE8. Am I missing something?

  • Weird behavior in referring to global variable. Is this a bug in javascript? Surely it isn't!

    - by Chandan .
    Consider the following piece of code. <html> <body> <script> var x = 5; //globally declared function showX() { alert("x="+x); //trying to display global value var x=10; //trying to create and initialize a local x } </script> <input type = "button" value="Show X" onclick="showX()"> </body> </html> The alert statement shows 'x=undefined'. And doesn't print the global value of x as expected. An equivalent java code would display 5! So, is it a bug? If not then how does one explain that behavior?

  • Advanced Web Browsing: hitting next with keyboard (single keystroke)

    - by Dan
    I have a website for class that is literally 1000's of pages long, with a next button at the bottom like this: Prev 1 2 3 4 Next With the following code, if that helps: <a href="javascript:gotoModuleObjective(1,1,34,17, 1, 0);">Prev</a> </td> <td align="center" width="10"> <font color="CC0000">1</font> </td> <td align="center" width="10"> <a href="javascript:gotoModuleObjective(1,24,33,2,1,0);">2</a> </td> <td align="center" width="10"> <a href="javascript:gotoModuleObjective(1,24,33,3,1,0);">3</a> </td> <td align="center" width="10"> <a href="javascript:gotoModuleObjective(1,24,33,4,1,0);">4</a> </td> <td align="right" style="white-space:nowrap;" width="30"> <a href="javascript:gotoModuleObjective(1, 24,33,2, 1, 0);">Next</a> </td> The numbers change depending on where you are. I would like to be able to, from the keyboard, hit the next button. I am using windows, but can switch to any browser, if this is only possible is a given browser. If this can be done with just one keystroke that would be wonderful. Like just hitting the forward arrow would automatically bring click the button called next and bring me to the next page. Is this possible? Thanks, Dan

  • How do I debug this javascript -- I don't get an error in Firebug but it's not working as expected.

    - by Angela
    I installed the plugin better-edit-in-place (http://github.com/nakajima/better-edit-in-place) but I dont' seem to be able to make it work. The plugin creates javascript, and also automatically creates a rel and class. The expected behavior is to make an edit-in-place, but it currently is not. Nothing happens when I mouse over. When I use firebug, it is rendering the value to be edited correctly: <span rel="/emails/1" id="email_1_days" class="editable">7</span> And it is showing the full javascript which should work on class editable. I didn't copy everything, just the chunks that seemed should be operationable if I have a class name in the DOM. // Editable: Better in-place-editing // http://github.com/nakajima/nakatype/wikis/better-edit-in-place-editable-js var Editable = Class.create({ initialize: function(element, options) { this.element = $(element); Object.extend(this, options); // Set default values for options this.editField = this.editField || {}; this.editField.type = this.editField.type || 'input'; this.onLoading = this.onLoading || Prototype.emptyFunction; this.onComplete = this.onComplete || Prototype.emptyFunction; this.field = this.parseField(); this.value = this.element.innerHTML; this.setupForm(); this.setupBehaviors(); }, // In order to parse the field correctly, it's necessary that the element // you want to edit in place for have an id of (model_name)_(id)_(field_name). // For example, if you want to edit the "caption" field in a "Photo" model, // your id should be something like "photo_#{@photo.id}_caption". // If you want to edit the "comment_body" field in a "MemberBlogPost" model, // it would be: "member_blog_post_#{@member_blog_post.id}_comment_body" parseField: function() { var matches = this.element.id.match(/(.*)_\d*_(.*)/); this.modelName = matches[1]; this.fieldName = matches[2]; if (this.editField.foreignKey) this.fieldName += '_id'; return this.modelName + '[' + this.fieldName + ']'; }, // Create the editing form for the editable and inserts it after the element. // If window._token is defined, then we add a hidden element that contains the // authenticity_token for the AJAX request. setupForm: function() { this.editForm = new Element('form', { 'action': this.element.readAttribute('rel'), 'style':'display:none', 'class':'in-place-editor' }); this.setupInputElement(); if (this.editField.tag != 'select') { this.saveInput = new Element('input', { type:'submit', value: Editable.options.saveText }); if (this.submitButtonClass) this.saveInput.addClassName(this.submitButtonClass); this.cancelLink = new Element('a', { href:'#' }).update(Editable.options.cancelText); if (this.cancelButtonClass) this.cancelLink.addClassName(this.cancelButtonClass); } var methodInput = new Element('input', { type:'hidden', value:'put', name:'_method' }); if (typeof(window._token) != 'undefined') { this.editForm.insert(new Element('input', { type: 'hidden', value: window._token, name: 'authenticity_token' })); } this.editForm.insert(this.editField.element); if (this.editField.type != 'select') { this.editForm.insert(this.saveInput); this.editForm.insert(this.cancelLink); } this.editForm.insert(methodInput); this.element.insert({ after: this.editForm }); }, // Create input element - text input, text area or select box. setupInputElement: function() { this.editField.element = new Element(this.editField.type, { 'name':this.field, 'id':('edit_' + this.element.id) }); if(this.editField['class']) this.editField.element.addClassName(this.editField['class']); if(this.editField.type == 'select') { // Create options var options = this.editField.options.map(function(option) { return new Option(option[0], option[1]); }); // And assign them to select element options.each(function(option, index) { this.editField.element.options[index] = options[index]; }.bind(this)); // Set selected option try { this.editField.element.selectedIndex = $A(this.editField.element.options).find(function(option) { return option.text == this.element.innerHTML; }.bind(this)).index; } catch(e) { this.editField.element.selectedIndex = 0; } // Set event handlers to automaticall submit form when option is changed this.editField.element.observe('blur', this.cancel.bind(this)); this.editField.element.observe('change', this.save.bind(this)); } else { // Copy value of the element to the input this.editField.element.value = this.element.innerHTML; } }, // Sets up event handles for editable. setupBehaviors: function() { this.element.observe('click', this.edit.bindAsEventListener(this)); if (this.saveInput) this.editForm.observe('submit', this.save.bindAsEventListener(this)); if (this.cancelLink) this.cancelLink.observe('click', this.cancel.bindAsEventListener(this)); }, // Event Handler that activates form and hides element. edit: function(event) { this.element.hide(); this.editForm.show(); this.editField.element.activate ?

  • Implementing features in an Entity System

    - by Bane
    After asking two questions on Entity Systems (1, 2), and reading some articles on them, I think that I understand them much better than before. But, I still have some uncertainties, and mainly they are about building a Particle Emitter, an Input system, and a Camera. I obviously still have some problems understanding Entity Systems, and they might apply to a whole other range of objects, but I chose these three because they are very different concepts and should cover a pretty big ground, and help me understand Entity Systems and how to handle problems like these myself, as they come along. I am building an engine in Javascript, and I've implemented most of the core features, which include: input handling, flexible animation system, particle emitter, math classes and functions, scene handling, a camera and a render, and a whole bunch of other things that engines usually support. Then, I read Byte56's answer that got me interested into making the engine into an Entity System one. It would still remain an HTML5 game engine with the basic Scene philosophy, but it should support dynamic creation of entities from components. These are some of the definitions from the previous questions, updated: An Entity is an identifier. It doesn't have any data, it's not an object, it's a simple id that represents an index in the Scene's list of all entities (which I actually plan to implement as a component matrix). A Component is a data holder, but with methods that can operate on that data. The best example is a Vector2D, or a "Position" component. It has data: x and y, but also some methods that make operating on the data a bit easier: add(), normalize(), and so on. A System is something that can operate on a set of entities that meet the certain requirements, usually they (the entities) need to have a specified (by the system itself) set of components to be operated upon. The system is the "logic" part, the "algorithm" part, all the functionality supplied by components is purely for easier data management. The problem that I have now is fitting my old engine concept into this new programming paradigm. Lets start with the simplest one, a Camera. The camera has a position property (Vector2D), a rotation property and some methods for centering it around a point. Each frame, it is fed to a renderer, along with a scene, and all the objects are translated according to it's position. Then the scene is rendered. How could I represent this kind of an object in an Entity System? Would the camera be an entity or simply a component? A combination (see my answer)? Another issues that is bothering me is implementing a Particle Emitter. For what exactly I mean by that, you can check out my video of it: http://youtu.be/BObargIMQsE. The problem I have with this is, again, what should be what. I'm pretty sure that particles themselves shouldn't be entities, as I want to support 10k+ of them, and creating that much entities would be a heavy blow on my performance, I believe. Or maybe not? Depends on the implementation, but anyone with experience: please, do answer. The last bit I wan't to talk about, which is also bugging me the most, is how input should be handled. In my current version of the engine, there is a class called Input. It's a handler that subscribes to browser's events, such as keypresses, and mouse position changes, and also it maintains an internal state. Then, the player class has a react() method, which accepts an input object as an argument. The advantage of this is that the input object could be serialized into JSON and then shared over the network, allowing for smooth multiplayer simulations. But how does this translate into an Entity System?

  • Why is jQuery so widely adopted versus other Javascript frameworks?

    - by Andrew Moore
    I manage a group of programmers. I do value my employees opinion but lately we've been divided as to which framework to use on web projects. I personally favor MooTools, but some of my team seems to want to migrate to jQuery because it is more widely adopted. That by itself is not enough for me to allow a migration. I have used both jQuery and MooTools. This particular essay tends to reflect how I feel about both frameworks. jQuery is great for DOM Manipulation, but seem to be limited to helping you do that. Feature wise, both jQuery and MooTools allow for easy DOM Selection and Manipulation: // jQuery $('#someContainer div[class~=dialog]') .css('border', '2px solid red') .addClass('critical'); // MooTools $('#someContainer div[class~=dialog]') .setStyle('border', '2px solid red') .addClass('critical'); Both jQuery and MooTools allow for easy AJAX: // jQuery $('#someContainer div[class~=dialog]') .load('/DialogContent.html'); // MooTools (Using shorthand notation, you can also use Request.HTML) $('#someContainer div[class~=dialog]') .load('/DialogContent.html'); Both jQuery and MooTools allow for easy DOM Animation: // jQuery $('#someContainer div[class~=dialog]') .animate({opacity: 1}, 500); // MooTools (Using shorthand notation, you can also use Fx.Tween). $('#someContainer div[class~=dialog]') .set('tween', {duration: 500}) .tween('opacity', 1); jQuery offers the following extras: Large community of supporters Plugin Repository Integration with Microsoft's ASP.NET and VisualStudio Used by Microsoft, Google and others MooTools offers the following extras: Object Oriented Framework with Classic OOP emulation for JS Extended native objects Higher consistency between browsers for native functions support. More easy code reuse Used by The World Wide Web Consortium, Palm and others. Given that, it seems that MooTools does everything jQuery does and more (some things I cannot do in jQuery and I can in MooTools) but jQuery has a smaller learning curve. So the question is, why did you or your team choose jQuery over another JavaScript framework? Note: While I know and admit jQuery is a great framework, there are other options around and I'm trying to take a decision as to why jQuery should be our choice versus what we use right now (MooTools)?

  • Javascript/CSS rollover menus are patented and subject to licensing?

    - by Scott B
    Very interesting finding that a client brought to my attention today regarding javascript style rollover menus. They got a call from their legal dept that they need to change the manner in which their rollover menu is activated (at the risk of having to pay license to continue using the navigation technique). Its no April fools joke, apparently this is really happening. Apparently a company named Webvention LLC has obtained enforcement rights to a patent, U.S. Patent No. 5,251,294 - "Accessing, assembling, and using bodies of Information." A menu link, that when rolled over, expands to show a list of categorized, related links. Dropdown menus and slide-out menus are examples of this patented navigational methodology. A key component of this patent is that the dropdown/slide-out action must be initiated by a rollover or mouseover event. If the dropdown/slide-out action is initiated by any other event, such as a mouse-click event, then this behavior is not in violation of the patent. Anyone ever heard of this or know of the validity of its claims? Website is here: http://www.webventionllc.com/

  • JavaScript: Is there a way to get Chrome to break on all errors?

    - by Alessandro Vernet
    I am looking for an equivalent in Chrome to the "break on all errors" functionality of Firebug. In the Scripts tab, Chrome has a "pause on all exceptions", but this is not quite the same as breaking on all errors. For instance, when loading a page with the following code, I would like Chrome to break on the line foo.bar = 42. Instead, even when enabling the "Pause on all exceptions", I don't get the expected result. <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Strict//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-strict.dtd"> <html xmlns="http://www.w3.org/1999/xhtml" xml:lang="en" lang="en"> <head> <script type="text/javascript"> function doError() { foo.bar = 42; } window.onload = function() { try { doError(); } catch (e) { console.log("Error", e); } } </script> </head> <body> </body> </html> You can try the code pasted above on this page.

  • IE7 - visited links revert to unvisted after page refresh

    - by Gerald
    Hello, A number of our users have just upgraded from IE6 to IE7. the upgreaded users are reporting an issue with visited links reverting to their unvisited color after a page refresh. This only happens to links that are using javascript instead of a hard coded URL: <script lang="JavaScript"> <!-- function LoadGoogle() { var LoadGoogle = window.open('http://www.google.com'); } --> </script> <a href="javascript:LoadGoogle()">Google using javascript</a> <a href="#" OnClick="javascript:LoadGoogle()">Google using javascript OnClick</a> The above links will revert back to the unvisited color whenever the page is refreshed. It doesn't matter if the page is refreshed because of a post back, manually hitting the refresh or f5 button, or from an auto-refresh function. Please note, the above code is an over simplification of what is actually happening, but I believe it illustrates the issue well enough. This is causing a problem for our users because we are providing them with a list of items that are all opened into new windows via javascript when they are clicked; and refresh the parent page when the users are finished with them. Each time the parent page is refreshed all of these links revert back to their unvisited color, so our users are losing track of which items they've worked on. I've been digging around and it looks like this is intended behavior. IE7 doesn't register these links with the browsers history. Does anyone know a work around that will allow us to keep these javascript links in the visited state without having to do a major overhaul of the apps code? Thank you.

  • OnmouseMove not work with SetTimeOut and Alerts in Chome

    - by Diogo Fernandes
    What's wrong with this code? It works in IE and FireFox, but Chrome does not work. The idea is that the function fnTimeOut will be triggered in 5 seconds after onmousemove. It´s ok. But when, in Chrome, I click on the button "ok" to function fnAlert is triggered instantly. It should be shot just 5 seconds after I move the mouse ... help me please. <input type="button" onclick="alert(1);" value="ok"> <script> document.onmousemove = fnTimeOut; var t = null; function fnAlert() { alert(2); } function fnTimeOut() { clearTimeout( t ); t = setTimeout( fnAlert, 5000 ); } </script>

  • Why would javascript click-areas not be working in IE8?

    - by Edward Tanguay
    I'm trying to find a bug in an old ASP.NET application which causes IE8 to not be able to click on the following "button" area in our application: <td width="150px" class="ctl00_CP1_UiCommandManager1i toolBarItem" valign="middle" onmouseout="onMouseOverCommand(this,1,'ctl00_CP1_UiCommandManager1',0,0);" onmouseover="onMouseOverCommand(this,0,'ctl00_CP1_UiCommandManager1',0,0);" onmousedown="onMouseDownCommand(this, 'ctl00_CP1_UiCommandManager1', 0, 0);" onmouseup="onMouseUpCommand(this, 'ctl00_CP1_UiCommandManager1', 0, 0);" id="ctl00_CP1_UiCommandManager1_0_0"> <span style="width:100%;overflow:hidden;text-overflow:ellipsis;vertical-align:middle;white-space:nowrap;"> NEW </span> </td> When we switch IE8 to IE7 compatibility mode, the problem disappears, IE7 is able to click on it. Since the above HTML is generated by a third party control (Janus, http://www.janusys.com/controls), we don't have the source code. has anyone experienced any similar problems with IE8? I've determined that it actually fires the onMouseDownCommand command also the CSS of the button area is different in IE8, it doesn't have color shading that it does in IE7. I can imagine that somewhere the HTML is not valid and IE8 being stricter is not playing along, but where? any advice on how to narrow in on this bug welcome ANSWER: Turned out to be that the application was not checking the navigator.agent for "MSIE 8.0" and was thus treating IE8 has a non-Internet-Explorer browser. Thanks Lazarus for the tip, the IE8 Javascript debugger is very nice, like a Firebug for IE, will be using it more!

  • Writing to a new window with javascript... get access denied

    - by Søren
    Hello gurus :) I have been struggling with this for a while now, and decided it was time to ask for help. I am trying to create a print function on an aspx page, and I am using javascript to do this: function PrintContentCell() { var display_setting = "toolbar=yes, location=no, directories=yes, menubar=yes,"; display_setting += "scrollbars=yes, width=750, height=600, left=100, top=25"; var content_innerhtml = document.getElementById("testTable").innerHTML; var document_print = window.open("Loading.htm", "", display_setting); document_print.document.open(); document_print.document.write('<html><head><title>Print</title></head>'); document_print.document.write('<body style="font-family:verdana; font-size:12px;" onLoad="self.print();self.close();" >'); document_print.document.write(content_innerhtml); document_print.document.write('</body></html>'); document_print.print(); document_print.document.close(); return false; } I get "Access Denied" when the script tries to write to the new window. The Loading.htm file is just a very slim html document writing out the text "Loading...". I had hoped this would work after reading this thread: http://stackoverflow.com/questions/735136/ie-6-7-access-denied-trying-to-access-a-popup-window-document Anybody can help?

  • Is Annotation in Javascript? If not, how to switch between debug/productive modes in declarative way

    - by Michael Mao
    Hi all: This is but a curious question. I cannot find any useful links from Google so it might be better to ask the gurus here. The point is: is there a way to make "annotation" in javascript source code so that all code snippets for testing purpose can be 'filtered out' when project is deployed from test field into the real environment? I know in Java, C# or some other languages, you can assign an annotation just above the function name, such as : // it is good to remove the annoying warning messages @SuppressWarnings("unchecked") public class Tester extends TestingPackage { ... } Basically I've got a lot of testing code that prints out something into FireBug console. I don't wanna manually "comment out" them because the guy that is going to maintain the code might not be aware of all the testing functions, so he/she might just miss one function and the whole thing can be brought down to its knees. One other thing, we might use a minimizer to "shrink" the source code into "human unreadable" code and boost up performance (just like jQuery.min), so trying to match testing section out of the mess is not possible for plain human eyes in the future. Any suggestion is much appreciated.
