  • Making Sense of DNS

    <b>Begin Linux:</b> "Domain Name Service (DNS) was created in 1983 out of the necessity to convert IP Addresses like 192.168.9.2 to domain names like example.com. DNS is a distributed database, what this means is that no one computer is used to maintain a complete database of all of the domains on the Internet. Instead this information is distributed across many computers."

    - by Kemrop
    Ok this will be quick. I am collecting data in div by inserting hidden input boxes before i eventually submit to the server. here is Javascript code. function appendToDiv() { var mydiv=document.getElementById("somediv"); var mydata=document.getElementsByName("description")[0].value; var myurl=document.getElementsByName("url")[0].value; var data=mydata+myurl; mydiv.innerHTML="<input type='hidden' name='sUrl[]'value='"+data+"'/" } I have an onchange event that keeps calling the above guy until i am satisfied that i have all i need to send to the server.Problem is only one input get appended to the div.What could i be missing.

  • jquery Troubles with binding to an element by id

    - by Alonzo
    Hi What im trying to do is that when the esc key is pressed on the text input field (id = txtSearch), some code will run. this is my code: $(document).ready(function() { $('#txtSearch').bind('keyup', function(e) { var characterCode; // literal character code will be stored in this variable if (e && e.which) { //if which property of event object is supported (NN4) e = e; characterCode = e.which; } else { characterCode = e.keyCode; } if (characterCode == 27) //if esc key { //do stuff } }); } It doesnt work for me. however, if i would change that line: $('#txtSearch').bind('keyup', function(e) { with: $(document).bind('keyup', function(e) { everything works. but i dont want to bind the keyup with esc to the whole document... any suggestions on how i can bind the the keyup only with the specific text search element? (or its containing div or something) Thanks!

  • print to Flash in C#

    - by Reinhard
    I need an easy way to show different document-types (.doc, .xls, .jpg...) in webpages. Ideally a user prints or saves that document and that document is automatically converted to Adobe-Flash. I know there are existing solutions to this. However, I would like to implement them in my own application, written in C#. Can anyone point me in a direction how to write a "Printer" in C#, where printable documents can be printed to, and that outputs a SWF-File? Thanks, Reinhard

  • jquery UI slider not working in Safari.

    - by Joe
    so i have the below code, which I think is fine: jQuery( function() { jQuery("#slider-vertical").slider( { orientation :"vertical", range :"min", min :0, max :100, value :50, slide : function(event, ui) { jQuery("#amount").val(ui.value); var movie = thisMovie('ClusterFlash'); fromScroll = jQuery("#amount").val(); if (movie) { currentSentiment = ((100 - fromScroll) / 100); movie.sentimentChange(currentSentiment); } } }); }); the 'movie' var above calls the following function, which seems to be where my problem is. function thisMovie(movieName) { if (navigator.appName.indexOf("Microsoft") != -1) { return window[movieName]; } if(document[movieName].length != undefined) { return document[movieName][1]; } return document[movieName]; } Any help would be appreciated.

  • How to find out where my memory is going

    - by the_mandrill
    I've got the situation where the cycle of loading and then closing a document eats up a few Mb of RAM. This memory isn't being leaked as something owns it and cleans it up when the app exits (Visual Leak Detector and the Mac Leaks tool show agreement on this). However, I'd like to find out where it's going. I'm assuming it's some sort of cache in the application that gets populated when the document loads but not freed when the document is closed. Which methods or tools could I use to find out where these allocations are being made?

  • Conditional Statements - If Then vs. Select Case

    - by cloyd800
    I'm a bit new to programming, and based on the few sources I've read both on the web and the books I'm learning to teach myself they are able to define what IF THEN and SELECT CASE conditional statements are, but have failed to give a comparison as to why I would use one over the other and what best practices decide this. If I'm understanding these conditional statements correctly, then both are based on a set of conditions with an outcome based around meeting these conditions, and if no conditions are met then an alternative outcome can be defined. I'm having trouble in understanding when I would use an IF THEN statement, and when I'd use a SELECT CASE statement, and what best practices are used to define this decision. Any insight on this would be greatly appreciated!

  • Is this time related process accounting stats gathering appropriate?

    - by Ceko Cakata
    Based on sys/acct.h (V1, not V3) I need to gather some user usage statistics based on a parser that parser the acct file line by line. The parser will run and parse the entire file every N seconds and I need to gather user statistics accumulated since the last run (N seconds back). I'm not sure what will be the most appropriate way to do it based on the info provided by sys/acct.h. Maybe something like this: if ((ac_btime + ac_etime) < (current_time - N)) { gather; } Also comp_t is said to be "floating-point value consisting of a 3-bit, base-8 exponent, and a 13-bit mantissa", but I think u_int16_t is just a unsigned short int. Should I be converting it to long it with the provided formula or not?

  • what's the javascript "var _gaq = _gaq || []; " for ?

    - by parvas
    The Async Tracking in google analytics looks like this: var _gaq = _gaq || []; _gaq.push(['_setAccount', 'UA-XXXXX-X']); _gaq.push(['_trackPageview']); (function() { var ga = document.createElement('script'); ga.type = 'text/javascript'; ga.async = true; ga.src = ('https:' == document.location.protocol ? 'https://ssl' : 'http://www') + '.google-analytics.com/ga.js'; var s = document.getElementsByTagName('script')[0]; s.parentNode.insertBefore(ga, s); })(); About The first line var _gaq = _gaq || []; I think it ensures that if _gaq is already defined we should use it otherwise we should an array. Can anybody explain what this is for ? Also, does it matter if _gaq gets renamed ? in other words does google analytics rely on a global object named _gaq ? Thanks Parvas

  • IE8 $('body').width() is 0 on $(window).load()

    - by allicarn
    On $(document).ready I run through a for loop twice and alert out the body's width ($('body').width();) each time through. I get a value I would expect (ex. 1092). On $(window).load I run through another for loop twice, also alerting out the body's width each time through. I get 0 the first time through (and the page looks completely blank behind the alert), and then a value I would expect the second time through (ex. 1092). This is an issue I am not able to replicate in a stripped-down example, nor any other browser (Chrome, Safari, Firefox, IE9, IE10). Does anyone have any ideas, or other things that I could test for? I am using $(window).load to cut up some divs based on their width, which is based on their font size, which is based on a webfont (which isn't necessarily loaded by the time $(document).ready fires).

  • How would one dynamically load Javascript that has been parsed as PHP?

    - by beatsforthemind
    I am looking to dynamically load javascript that has been parsed as PHP so that I will be able to pass PHP variables to javascript, and then load this file into the primary PHP document. I have a document called myscript.js.php that includes the javascript and PHP. I attempted to load it into the primary document using jQuery's getScript like this: $.getScript("myscript.js.php", function() { alert('loaded script.'); }); This attempt failed - I am assuming because of the .php extension on the file. Is there anyway to dynamically load javascript that includes PHP? I have a few session variables that I am looking to pass through javascript that will be updated frequently, creating a need for the javascript to be reloaded.

  • Why isn't this working - using :not() with an event handler

    - by james emanon
    I seem to have another issue that I am not conquering. Real simple premise. I have a mousedown event, and basically IF one particular element on the page is clicked, I want nothing to happen, else I want hide() some div. $(function(){ $("document :not(#_ignorelement)").mousedown(function(event){ if($('#_hidethiselement').length){ $('#_hidethiselement').hide(); } }) }) That is not working at all. I also tried the following: $(document).not($("#_ignorelement")).mousedown(function(event){ $(document).not("_ignorelement").mousedown(function(event){ IF I can solve that, curious how I would actually have ":not" encompass the parent div, like so: $().not("_ignoreelement").parent().closest('div').mousedown(function Because the element "_ignorelement" is an anchor tag that is in a div. Wonder how I can use the parent div perhaps, instead of the anchor tag. Anyways, any help would be appreciated.
