Firing a Keyboard Event at the Body - JavaScript (?)

- by user317985

I've done a lot of research on this but have come up empty handed. What I would like to do is invoke or create an event for the right arrow key (Key Code 39). I was planning on using an onclick event inside an tag to go to a function where this event could be 'fired'. Any help would be appreciated. If anyone needs context, I have a jQuery content slider that's functionality is very hard to alter and currently the functionality I need to emulate only occurs when a user hits the right arrow on their keyboard. What I would like to do is tie an onclick() event to a image that when clicked on fires the right keyboard event and the content will slide. Please let me know if I can provide further details or explanation. My working demo for this is: http://greenplanet3d.com

Inserting a newline into a pre tag (IE, Javascript)

- by Itay

In IE when I insert text into a <pre> tag the newlines are ignored: <pre id="putItHere"></pre> <script> function putText() { document.getElementById("putItHere").innerHTML = "first line\nsecond line"; } </script> Using \r\n instead of a plain \n does not work. <br/> does work but inserts an extra blank line in FF, which is not acceptable for my purposes.

Record/playback keystrokes in textfield using Javascript

- by James

Is it possible to record a user's input into an HTML textfield, and playback at a later date in realtime? One way I can think of would be to capture each keyDown event and the time delta (accurate to a few hundred ms), and store the pairs together. Can you think of a better/more efficient way?

JavaScript: Replacement for XMLSerializer.seralizeToString()?

- by NRaf

I'm developing a website using the Seam framework and the RichFaces AJAX library (these isn't really all that important to the problem at hand - just some background). I seem to have uncovered a bug, however, in RichFaces which, in certain instances, will cause AJAX-based updating to fail in IE8 (see here for more info: http://community.jboss.org/message/585737). The following is the code where the exception is occurring: var anchor = oldnode.parentNode; if(!window.opera && !A4J.AJAX.isWebkitBreakingAmps() && oldnode.outerHTML && !oldnode.tagName.match( /(tbody|thead|tfoot|tr|th|td)/i ) ){ LOG.debug("Replace content of node by outerHTML()"); if (!Sarissa._SARISSA_IS_IE || oldnode.tagName.toLowerCase()!="table") { try { oldnode.innerHTML = ""; } catch(e){ LOG.error("Error to clear node content by innerHTML "+e.message); Sarissa.clearChildNodes(oldnode); } } oldnode.outerHTML = new XMLSerializer().serializeToString(newnode); } The last line (the one with XMLSerializer) is where the exception is occurring in IE. I was wondering if anyone knows of any replacement method / library / etc I could use there (only on IE is fine). Thanks.

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?

How to make this JavaScript much faster?

- by Ralph

Still trying to answer this question, and I think I finally found a solution, but it runs too slow. var $div = $('<div>') .css({ 'border': '1px solid red', 'position': 'absolute', 'z-index': '65535' }) .appendTo('body'); $('body *').live('mousemove', function(e) { var topElement = null; $('body *').each(function() { if(this == $div[0]) return true; var $elem = $(this); var pos = $elem.offset(); var width = $elem.width(); var height = $elem.height(); if(e.pageX > pos.left && e.pageY > pos.top && e.pageX < (pos.left + width) && e.pageY < (pos.top + height)) { var zIndex = document.defaultView.getComputedStyle(this, null).getPropertyValue('z-index'); if(zIndex == 'auto') zIndex = $elem.parents().length; if(topElement == null || zIndex > topElement.zIndex) { topElement = { 'node': $elem, 'zIndex': zIndex }; } } }); if(topElement != null ) { var $elem = topElement.node; $div.offset($elem.offset()).width($elem.width()).height($elem.height()); } }); It basically loops through all the elements on the page and finds the top-most element beneath the cursor. Is there maybe some way I could use a quad-tree or something and segment the page so the loop runs faster?

jquery javascript error using $(...) selector

- by waitinforatrain

Hi, I'm migrating some old code to jquery: xmlHttp.onreadystatechange = function() { if (xmlHttp.readyState == 4) { $("#" + ajaxArea).html (xmlHttp.responseText); $("#" + ajaxArea).attr('title', 'Login'); $("#" + ajaxArea).dialog({ height : 140, modal : true }); } }; where ajaxArea is the ID of a DIV in the HTML. The dialog bit is basically adapted from the jQuery example here: http://jqueryui.com/demos/dialog/#modal All of it works fine up until the last line. Firefox throws an error that simply says "$(" for that line. Anyone know what might be causing this?

transform file/directory structure into 'tree' in javascript

- by dave

I have an array of objects that looks like this: [{ name: 'test', size: 0, type: 'directory', path: '/storage/test' }, { name: 'asdf', size: 170, type: 'directory', path: '/storage/test/asdf' }, { name: '2.txt', size: 0, type: 'file', path: '/storage/test/asdf/2.txt' }] There could be any number of arbitrary path's, this is the result of iterating through files and folders within a directory. What I'm trying to do is determine the 'root' node of these. Ultimately, this will be stored in mongodb and use materialized path to determine it's relationships. In this example, /storage/test is a root with no parent. /storage/test/asdf has the parent of /storage/test which is the parent to /storage/test/asdf/2.txt. My question is, how would you go about iterating through this array, to determine the parent's and associated children? Any help in the right direction would be great! Thank you

How to access a variable outside a function in Javascript

Am I missing something here?

Selecting an option with javascript

- by Fibericon

I have a drop down menu that I want to have selected on page load. This is what I'm using at the moment: var selector = document.getElementById("action_person").firstChild; var n = 0; while(selector.options[n] != null) { if(selector.options[n].value == "person") { selector.options.selectedIndex = n; } n++; } I've also tried replacing selector.options.selectedIndex = n with selector.options[n].selected = true. However, it never selects for me. It always shows the item at the top of the drop down. I've verified that the value "person" does exist in the drop down, and that the variable "selector" does point to a valid drop down. What am I doing wrong here?

Javascript: move the "view point" of the browser

- by ArchJ

I have a page with many out-of-bounds contents and since I set body{overflow:hidden}, they are not outside the viewport. So I want to attach a function to a button which would move the PoV of the browser so that the out-of-bounds contents would come into the viewport. What I can think of now is to set body{position:relative} and use jQuery to animate() the body instead. But in terms of performance, is there a better way to achieve that?

Implementing zoom on a fixed point, javascript/canvas

I want to implement zooming on the mouse pointer with the mouse wheel. That is scaling the image while the point under the mouse pointer stays fixed. Here is my code, which doesn't work very well var scala = 1 + event.wheelDelta / 1000; canvas.context.translate(-canvas.mouse.x * ( scala - 1 ) / canvas.scale,-canvas.mouse.y * ( scala - 1 ) / canvas.scale); canvas.context.scale(scala,scala); canvas.scale *= scala; //canvas.scale is my variable that is initially set to 1. //canvas.mouse is my variable that represents the mouse position relative to the canvas

javascript pop-up menu help

- by baiano

I am working on a project similar to a table where the user will be able to add rows. Right now there is just one row type available but I would like to give the user the ability to select from a list without changing the layout of the page. So, I put together a menu that appears on mouseover of the 'add row' link and disappears on mouseout (with a slight delay and fade in/out) using mootools event listeners. It looks like: I am now trying to figure out an easy way to make it so that the list stays available when the user's mouse leaves the 'add a row' link to go to select an item from the list. I looked through various mootools add-ons and tutorial but didn't find anything all that helpful. Does anyone know of a good tutorial guide me through this or can otherwise point me in the right direction here?
