  • Issue editing class style properties using js - issue is with IE

    - by Nick
    I have a function to edit the style properties of a class Unfortunately IE does not seem to like it but it does not give me an error. Does anyone know what the issue is? Thanks in advance function myRemoveElement(id) { var Node = document.getElementById(id); Node.parentNode.removeChild(Node); } function boolyChangeFoo(width1, width2, width3, width4) { if(typeof style == 'undefined') { var append = true; myStyle = document.createElement('style'); } else { while (myStyle.hasChildNodes()) { myStyle.removeChild(myStyle.firstChild); } } if (document.getElementById('my_custom_styles')) { myRemoveElement('my_custom_styles'); } var head = document.getElementById('myltd_popup_1'); var rules = document.createTextNode('.my_price_comp_inner { width: ' + width1 + '}' + '.merch_coupons_summary { width: ' + width2 + '}' + '.merch_coupons_data { width: ' + width3 + '}' + '.my_coupon_prod_item { width: ' + width4 + '}' ); myStyle.setAttribute('type','text/css'); myStyle.setAttribute('id', 'my_custom_styles'); if(myStyle.styleSheet) { myStyle.styleSheet.cssText = rules.nodeValue; } else { myStyle.appendChild(rules); } //alert(myStyle); if(append === true) head.appendChild(myStyle); }

  • Open source / commercial alternative for jiffy.js?

    - by Marcel
    Hi, we'd like to measure "client side web site performance". i.e. we would like to have answers to the following questions: how long did it takt to load and render a webpage (including alle graphics scripts etc.) this bundled with additional informations like user-agent, operating system etc. a graphical tool to analyze the data would be perfect I know jiffy ( http://code.google.com/p/jiffy-web/wiki/Jiffy_js ) but that isn't maintained anymore. I would prefer either a hosted solution (like google analytics) or a java based solution that we deploy for ourselves. Do you know something like that? Thanks, Marc

  • Significant new inventions in computing since 1980

    - by Alan Kay
    This question arose from comments about different kinds of progress in computing over the last 50 years or so. I was asked by some of the other participants to raise it as a question to the whole forum. Basic idea here is not to bash the current state of things but to try to understand something about the progress of coming up with fundamental new ideas and principles. I claim that we need really new ideas in most areas of computing, and I would like to know of any important and powerful ones that have been done recently. If we can't really find them, then we should ask "Why?" and "What should we be doing?"

  • Need help with cycle in JS

    - by antiarchitect
    I have such function, that adds a grid of droppables: function AddClassroomDrops(grid, weeks, days, times) { for(week = 1; week <= weeks; week++) { for (day = 1; day <= days; day++) { for (time = 1; time <= times; time++ ) { Droppables.add('container_grid'+ grid + '_week' + week + '_day' + day + '_time' + time, { accept: 'pair', hoverclass : 'hovered_receiver', onDrop: function(pair, receiver) { new Ajax.Request( '/pairs/'+pair.id+'/update_on_drop', { method : 'put', parameters : { classroom : grid, week : week, day : day, time : time, container : receiver.id } } ); } }); } } } } The problem is that params of Ajax.Request (week, day, time) are always equal to weeks + 1, times + 1, days + 1. But they must vary according to the cycle.

  • Client/JS Framework for "Unsaved Data" Protection?

    - by Kevin Dostalek
    Hey all- we have a typical web application that is essentially a data entry application with lots of screens some of which have some degree of complexity. We need to provide that standard capability on making sure if the user forgets to click the "Save" button before navigating away or closing their browser they get a warning and can cancel (but only when there is unsaved or dirty data). I know the basics of what I've got to do-- in fact I'm sure I've done it all before over the years (tie in to onbeforeunload, track the "dirty" state of the page, etc...) but before I embark on coding this YET AGAIN, does anyone have some suggestions for libraries already out there (free or otherwise) that will help out? Thanks!

  • Who in the software world do you admire the most?

    - by David McGraw
    In an effort to spark some discussion and to find interesting people that I didn't know about, is there anybody around the software industry that you really admire? Perhaps admire is the wrong choice of word, but I'm sure there is somebody out there that has impacted you in a minor way. What did you learn from this individual that defines what you try to achieve today?

  • Anyone familiar with CurvyCorners JS?

    - by Kyle Sevenoaks
    I am trying to implement the CurvyCorners script onto the site: euroworker.no. It reports back that certain CSS values don't exist on the page, how I can I turn off this alert? Found the alert code: if (j === null) curvyCorners.alert("No object with ID " + arg + " exists yet.\nCall curvyCorners(settings, obj) when it is created.");

  • Why do C compilers prepend underscores to external names?

    - by Michael Burr
    I've been working in C for so long that the fact that compilers typically add an underscore to the start of an extern is just understood... However, another SO question today got me wondering about the real reason why the underscore is added. A wikipedia article claims that a reason is: It was common practice for C compilers to prepend a leading underscore to all external scope program identifiers to avert clashes with contributions from runtime language support I think there's at least a kernel of truth to this, but also it seems to no really answer the question, since if the underscore is added to all externs it won't help much with preventing clashes. Does anyone have good information on the rationale for the leading underscore? Is the added underscore part of the reason that the Unix creat() system call doesn't end with an 'e'? I've heard that early linkers on some platforms had a limit of 6 characters for names. If that's the case, then prepending an underscore to external names would seem to be a downright crazy idea (now I only have 5 characters to play with...).

  • Seeking through a streamed MP3 file with HTML5 <audio> tag

    - by Kyle Slattery
    Hopefully someone can help me out with this. I'm playing around with a node.js server that streams audio to a client, and I want to create an HTML5 player. Right now, I'm streaming the code from node using chunked encoding, and if you go directly to the URL, it works great. What I'd like to do is embed this using the HTML5 <audio> tag, like so: <audio src="http://server/stream?file=123"> where /stream is the endpoint for the node server to stream the MP3. The HTML5 player loads fine in Safari and Chrome, but it doesn't allow me to seek, and Safari even says it's a "Live Broadcast". In the headers of /stream, I include the file size and file type, and the response gets ended properly. Any thoughts on how I could get around this? I certainly could just send the whole file at once, but then the player would wait until the whole thing is downloaded--I'd rather stream it.

  • jquery js how to avoid massive onmouseover onmouseout firing

    - by stephan
    i have a table with some columns. in each of them is a picture where i have a onmouseover onmouseout event on it, which show a message in a div and hide the msg. my problem is - after a user goes quick from left to right (and moving) over a lot o images. all mouseover/out events of the images where executed, which looks stupid... is it possible to rearrange the internal event stack to avoid this? so that he executes only the current (mostly the first event) - and than the last one, if it is not same type eg. if mouseover over first image is executed and mouse moving position stops over an image 3times next the first one. i can avoid all other events firing, because the mouse stopped over an image and the mouseover is like the one where i stopped with the mouse. how can i avoid this multiple event firing?!

  • Ember multiple property changes but want to trigger single event

    - by Ankur Agarwal
    I have a ArrayController for date picker with properties to and from. Now when user selects a new date range from the UI both to and from value changes. So a function which observers on to and from is trigger twice for a single change in date range. I want to trigger the function only one every date range change. Any suggestions how to do that with ember app = Ember.Application.create(); app.Time = Ember.ArrayController.create({ to: null, from: null, rootElement: "#time", debug1: function() { this.set('to', 1); this.set('from', 2); }, debug2: function() { this.setProperties( { 'to': 3, 'from': 4 }); }, debug3: function() { this.beginPropertyChanges(); this.set('to', 5); this.set('from', 6); this.endPropertyChanges(); }, search: function() { alert('called'); }.observes('to', 'from') }); View in JS Fiddle

  • Django, CSRF protection and js generated form

    - by Neewok
    I have to create a form dynamically via javascript (yeah, that sounds ugly, but read this for the reason) and wants to make its submission CSRF proof. Usually, I use the @csrf_protect decorator in my views, and the {% csrf_token %} tag in my templates, as recommanded in the doc. But what should I do with a client-side generated form ? If I add a '/get_token/' view to generate a token on the server and obtain its value (say, via JSONP), then that means that I'm creating a backdoor an attacker could use to bypass the protection. Kinda head-scratching. What would you recommand ?

  • keep HTMLformat after replace some text (using PHP and JS)

    - by Sadi
    I would like modify HTML like I am <b>Sadi, novice</b> programmer. to I am <b>Sadi, learner</b> programmer. To do it I will search using a string "novice programmer". How can I do it please? Any idea? Thank you Sadi More clarification: I get some nice reply with possible solution. But please keep posting if you have any idea in mind. I would like to more clarify the problem just in case anyone missed it. Main post shows the problem as an example scenario. 1) Now the problem is find and replace some string without considering the tags. The tags may shows up within a single word. String may contain multiple word. Tag only appear in the content string or the document. The search phrase never contain any tags. We can easily remove all tags and do some text operation. But here the another problem shows up. 2) The tags must be preserve, even after replacing the text. That is what the example shows. Thank you Again for helping

  • Why is the software world full of status codes?

    - by David V McKay
    Why did programmers ever start using status codes? I mean, I guess I could imagine this might be useful back in the days when a text string was an expensive resource. WAYYY back then. But even after we had megabytes of memory to work with, we continued to use them. What possible advantage could there be for obfuscating the meaning of an error message or status message behind a status code?

  • explanation about prototype.js function binding code

    - by resopollution
    From: http://ejohn.org/apps/learn/#2 Function.prototype.bind = function(){ var fn = this, args = Array.prototype.slice.call(arguments), object = args.shift(); return function(){ return fn.apply(object, args.concat(Array.prototype.slice.call(arguments))); }; }; Can anyone tell me why the second return is necessary (before fn.apply)? Also, can anyone explain why args.concat is necessary? Why wouldn't it be re-written as: fn.apply(object, args) instead of return fn.apply(object, args.concat(Array.prototype.slice.call(arguments)));

  • Why has anybody ever used COBOL?

    - by sarzl
    I know: You and me hate COBOL. I took a look at a lot of code examples and it didn't take me long to know why everybody tries to avoid it. So I really have no idea: Why was COBOL ever used? I mean: Hey - there was Fortran before it, and Fortran looks like a jesus-language compared to COBOL. This isn't argumentative but historical as I'm young and didn't even know about COBOL before 4 months.

  • Cobol: science and fiction

    - by user847
    There are a few threads about the relevance of the Cobol programming language on this forum, e.g. this thread links to a collection of them. What I am interested in here is a frequently repeated claim based on a study by Gartner from 1997: that there were around 200 billion lines of code in active use at that time! I would like to ask some questions to verify or falsify a couple of related points. My goal is to understand if this statement has any truth to it or if it is totally unrealistic. I apologize in advance for being a little verbose in presenting my line of thought and my own opinion on the things I am not sure about, but I think it might help to put things in context and thus highlight any wrong assumptions and conclusions I have made. Sometimes, the "200 billion lines" number is accompanied by the added claim that this corresponded to 80% of all programming code in any language in active use. Other times, the 80% merely refer to so-called "business code" (or some other vague phrase hinting that the reader is not to count mainstream software, embedded systems or anything else where Cobol is practically non-existent). In the following I assume that the code does not include double-counting of multiple installations of the same software (since that is cheating!). In particular in the time prior to the y2k problem, it has been noted that a lot of Cobol code is already 20 to 30 years old. That would mean it was written in the late 60ies and 70ies. At that time, the market leader was IBM with the IBM/370 mainframe. IBM has put up a historical announcement on his website quoting prices and availability. According to the sheet, prices are about one million dollars for machines with up to half a megabyte of memory. Question 1: How many mainframes have actually been sold? I have not found any numbers for those times; the latest numbers are for the year 2000, again by Gartner. :^( I would guess that the actual number is in the hundreds or the low thousands; if the market size was 50 billion in 2000 and the market has grown exponentially like any other technology, it might have been merely a few billions back in 1970. Since the IBM/370 was sold for twenty years, twenty times a few thousand will result in a couple of ten-thousands of machines (and that is pretty optimistic)! Question 2: How large were the programs in lines of code? I don't know how many bytes of machine code result from one line of source code on that architecture. But since the IBM/370 was a 32-bit machine, any address access must have used 4 bytes plus instruction (2, maybe 3 bytes for that?). If you count in operating system and data for the program, how many lines of code would have fit into the main memory of half a megabyte? Question 3: Was there no standard software? Did every single machine sold run a unique hand-coded system without any standard software? Seriously, even if every machine was programmed from scratch without any reuse of legacy code (wait ... didn't that violate one of the claims we started from to begin with???) we might have O(50,000 l.o.c./machine) * O(20,000 machines) = O(1,000,000,000 l.o.c.). That is still far, far, far away from 200 billion! Am I missing something obvious here? Question 4: How many programmers did we need to write 200 billion lines of code? I am really not sure about this one, but if we take an average of 10 l.o.c. per day, we would need 55 million man-years to achieve this! In the time-frame of 20 to 30 years this would mean that there must have existed two to three million programmers constantly writing, testing, debugging and documenting code. That would be about as many programmers as we have in China today, wouldn't it? Question 5: What about the competition? So far, I have come up with two things here: 1) IBM had their own programming language, PL/I. Above I have assumed that the majority of code has been written exclusively using Cobol. However, all other things being equal I wonder if IBM marketing had really pushed their own development off the market in favor of Cobol on their machines. Was there really no relevant code base of PL/I? 2) Sometimes (also on this board in the thread quoted above) I come across the claim that the "200 billion lines of code" are simply invisible to anybody outside of "governments, banks ..." (and whatnot). Actually, the DoD had funded their own language in order to increase cost effectiveness and reduce the proliferation of programming language. This lead to their use of Ada. Would they really worry about having so many different programming languages if they had predominantly used Cobol? If there was any language running on "government and military" systems outside the perception of mainstream computing, wouldn't that language be Ada? I hope someone can point out any flaws in my assumptions and/or conclusions and shed some light on whether the above claim has any truth to it or not.

    Let me explain what I'm trying to do. I want to make a simple box which counts down numbers at intervals I specify. For example, I'd like to set it to start at 150, and then I want to set it to drop by 15 every 30 seconds. Is this possible with AJAX/Javascript? If so, could someone point me in the right direction? Would really appreciate any help on this script, been Googling for hours now! :( Cheers Kieran

  • how to run javascript from c# code ?

    - by dotnetcoder
    I have a webrequest that returns a html response which has form inside with hidden fields with some javascript that submits the form automatically on pageload ( if this was run in a browser). If I save this file as *.html and run this file in browser , the java script code automatically posts the form and the output is excel file. I want to be able to generate this file from a c# code which is not running in broswer. I tried mocking thr form post but its complicated and has various scenarios based on the original webrequest querystring. any pointers.... i know its not possible to probably run JS code that posts the form - from within c# code but still thought of chekcing if someone has done that.

  • Selecting and inserting text at cursor location in textfield with JS/jQuery

    - by IceCreamYou
    Hello. I have developed a system in PHP which processes #hashtags like on Twitter. Now I'm trying to build a system that will suggest tags as I type. When a user starts writing a tag, a drop-down list should appear beneath the textarea with other tags that begin with the same string. Right now, I have it working where if a user types the hash key (#) the list will show up with the most popular #hashtags. When a tag is clicked, it is inserted at the end of the text in the textarea. I need the tag to be inserted at the cursor location instead. Here's my code; it operates on a textarea with class "facebook_status_text" and a div with class "fbssts_floating_suggestions" that contains an unordered list of links. (Also note that the syntax [#my tag] is used to handle tags with spaces.) maxlength = 140; var dest = $('.facebook_status_text:first'); var fbssts_box = $('.fbssts_floating_suggestions'); var fbssts_box_orig = fbssts_box.html(); dest.keyup(function(fbss_key) { if (fbss_key.which == 51) { fbssts_box.html(fbssts_box_orig); $('.fbssts_floating_suggestions .fbssts_suggestions a').click(function() { var tag = $(this).html(); //This part is not well-optimized. if (tag.match(/W/)) { tag = '[#'+ tag +']'; } else { tag = '#'+ tag; } var orig = dest.val(); orig = orig.substring(0, orig.length - 1); var last = orig.substring(orig.length - 1); if (last == '[') { orig = orig.substring(0, orig.length - 1); } //End of particularly poorly optimized code. dest.val(orig + tag); fbssts_box.hide(); dest.focus(); return false; }); fbssts_box.show(); fbssts_box.css('left', dest.offset().left); fbssts_box.css('top', dest.offset().top + dest.outerHeight() + 1); } else if (fbss_key.which != 16) { fbssts_box.hide(); } }); dest.blur(function() { var t = setTimeout(function() { fbssts_box.hide(); }, 250); }); When the user types, I also need get the 100 characters in the textarea before the cursor, and pass it (presumably via POST) to /fbssts/load/tags. The PHP back-end will process this, figure out what tags to suggest, and print the relevant HTML. Then I need to load that HTML into the .fbssts_floating_suggestions div at the cursor location. Ideally, I'd like to be able to do this: var newSuggestions = load('/fbssts/load/tags', {text: dest.getTextBeforeCursor()}); fbssts_box.html(fbssts_box_orig); $('.fbssts_floating_suggestions .fbssts_suggestions a').click(function() { var tag = $(this).html(); if (tag.match(/W/)) { tag = tag +']'; } dest.insertAtCursor(tag); fbssts_box.hide(); dest.focus(); return false; }); And here's the regex I'm using to identify tags (and @mentions) in the PHP back-end, FWIW. %(\A(#|@)(\w|(\p{L}\p{M}?))+\b)|((?<=\s)(#|@)(\w|(\p{L}\p{M}?))+\b)|(\[(#|@).+?\])%u Right now, my main hold-up is dealing with the cursor location. I've researched for the last two hours, and just ended up more confused. I would prefer a jQuery solution, but beggars can't be choosers. Thanks!
