  • How to run Javascript code before document is completely loaded (using jQuery)

    - by eliza sahoo
    Hi all, I am sahring atip with you all.Please add on to this discussion. JQuery helps faster page load than javascript. JQuery functions are fired when the related elements are loaded, instead of complete pageload. This is a common practice to call a javascript function when page is loaded like window.onload = function(){ alert("Mindfire") } or Inside of which is the code that we want to run right when the page is loaded. Problematically, however, the Javascript code isn't run until all images are finished downloading (this includes banner ads). The reason for using window.onload in the first place is due to the fact that the HTML 'document' isn't finished loading yet, when you first try to run your code. To circumvent both problems, jQuery has a simple statement that checks the document and waits until it's ready to be manipulated, known as the ready event $(document).ready(function() { // Your code here });

  • javafx 2, CSS and focus disappearing

    - by AgostinoX
    I've created a very simple CSS that styles two buttons. To the first has just been added a padding. To the second has been set the -fx-background-color, but the value is taken from caspian.css, that is the value it should have before it had been set. .first-style { -fx-padding: 20 5 1 5; } .second-style { -fx-background-color: -fx-shadow-highlight-color, -fx-outer-border, -fx-inner-border, -fx-body-color; } At this point i experience a strange behavior: the focus decoration stops working, and the second button doesn't get its blue border when focused. What's happening?

  • Javascript timer in parent window is cancelled on child window close

    - by Tom Carter
    I have a user UserControl on a web page. There is a javascript timer started by the control on the client that causes a web service to be called every few seconds. If the user clicks on the control a new browser window is opened (with window.open() ) to show a different page. Note the onclick returns false so there is no postback to the page. The page displayed in the second window also has a timer that operates in the same way as the first (calls a WebService at intervals). Upto this point everything is fine - each of the timers continue to run in their respective window. However, when I close the second window (either by clicking on the cross of the window or by calling self.close() ) the timer in the first stops. I've no idea why. Is there some relationship between the opener and opened window that I'm missing ?

  • Using an array in embedded x86 assembly??

    - by Mark V.
    Hey all I have a method (C++) that returns a character and takes an array of characters as its parameters. I'm messing with assembly for the first time and just trying to return the first character of the array in the dl register. Here's what I have so far: char returnFirstChar(char arrayOfLetters[]) { char max; __asm { push eax push ebx push ecx push edx mov dl, 0 mov eax, arrayOfLetters[0] xor edx, edx mov dl, al mov max, dl pop edx pop ecx pop ebx pop eax } return max; } For some reason this method returns a ? Any idea whats going on? Thanks

  • Rails app is prepending tunnlr web address when using link helpers

    - by mathee
    I set up facebooker to tunnel my Ruby on Rails application. The issue is that I would like to test locally. That is, I don't want to have to start a tunnel every time I want to see my changes. Right now, when I start the application using ruby script/server (not calling rake facebooker:tunnel:background_start beforehand), links created by helpers (e.g., stylesheet_link_tag, javascript_include_tag, image_tag) are prepended with my tunnlr address: http://web1.tunnlr.com:myPort/. (For example, a CSS link looks like this in the page source: http://web1.tunnlr.com:myPort//stylesheets/appName.css?1234567890.) I don't want that functionality; I can't see my CSS or JavaScript changes without starting the tunnel first. I want the links to be relative to what's running on my machine, not the tunnel. So, stylesheet_link_tag should produce /stylesheets/appName.css?1234567890. Does anyone know why it's doing that in the first place and how to fix it? Thanks in advance.

  • VB.Net variable declaration

    - by dcp
    I notice that both of these compile without any compiler warnings or errors, even with Option Strict and Option Explicit both turned on: Dim x As Exception = New Exception("this is a test") Dim y = New Exception("this is another test") My question is, is it more proper to use the first way (see variable x) or the second way (see variable y)? My guess is that VB doesn't need the As clause since the variable is being initialized in place, so the compiler can infer the type. I tend to like the first way as it just "feels" right and is more consistent with other languages like C#, just wondered if there was some good reason for one way over the other. I guess it's really personal choice.

  • Not able to delete list which dynamically created with jquery.

    - by shin
    I have two html here. The first one is dynamically generated by php and second one is just html to test. I also have the following jquery. When I click a cross with class delete in the second ones(plain html), it works nicely. However when I click a cross in the first ones, it does not work. It redirect me to the home page with # at the end. I am hoping someone point out what I am doing wrong. Thank in advance. HTML First part (dyanmicall generated) <ul style="display: block;" id="message"> <li class="41"> <span class="user"><strong>shin</strong></span> <span class="msg"> delete this as well</span> <span class="date">2010-01-15 07:47:31</span> <a href="#" id="41" class="delete">x</a> <div class="clear"></div></li> <li class="40"> <span class="user"><strong>shin</strong></span> <span class="msg"> delete me as well</span> <span class="date">2010-01-14 16:01:44</span> <a href="#" id="40" class="delete">x</a> <div class="clear"></div></li> ... ...</ul> Second part which is plain html <ul id="another"> <li><a href="#">you can't delete me</a></li> <li><a href="#" class="delete">delete this</a></li> <li><a href="#" class="delete">delete this</a></li> </ul> Here is jquery $(".delete").click(function(event) { event.preventDefault(); loading.fadeIn(); var commentContainer = $(this).parent(); var id = $(this).attr("id"); // var string = 'id='+ id ; $.ajax({ type: "POST", url: "index.php/admin/messages/changestatus/"+id, // data: string, cache: false, success: function(){ commentContainer.slideUp('slow', function() {$(this).remove();}); loading.fadeOut(); } }); return false; }); I am using CodeIgniter by the way.

  • How to cache and store objects and set an expire policy in android?

    - by virsir
    I have an app fetch data from internet, for better performance and bandwidth, I need to implement a cache layer. There are two different data coming from the internet, one is changing every one hour and another one does not change basically. So for the first type of data, I need to implement an expire policy to make it self deleted after it was created for 1 hour, and when user request that data, I will check the storage first and then goto internet if nothing found. I thought about using a SharedPrefrence or SQLDatabase to store the json data or serialized object string. My question is: 1) What should I use, SharedPrefrence or SQLDatabase or anything else, a piece of data is not big but there are maybe many instances of that data. 2) How to implement that expire system.

  • What does SQL Server execution plan show?

    - by tim
    There is the following code: declare @XmlData xml = '<Locations> <Location rid="1"/> </Locations>' declare @LocationList table (RID char(32)); insert into @LocationList(RID) select Location.RID.value('@rid','CHAR(32)') from @XmlData.nodes('/Locations/Location') Location(RID) insert into @LocationList(RID) select A2RID from tblCdbA2 Table tblCdbA2 has 172810 rows. I have executed the batch in SSMS with “Include Actual execution plan “ and having Profiler running. The plan shows that the first query cost is 88% relative to the batch and the second is 12%, but the profiler says that durations of the first and second query are 17ms and 210 ms respectively, the overall time is 229, which is not 12 and 88.. What is going on? Is there a way how I can determine in the execution plan which is the slowest part of the query?

  • Getting started with XSD validation with .NET

    - by Rosarch
    Here is my first attempt at validating XML with XSD. The XML file to be validated: <?xml version="1.0" encoding="utf-8" ?> <config xmlns="Schemas" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="config.xsd"> <levelVariant> <filePath>SampleVariant</filePath> </levelVariant> <levelVariant> <filePath>LegendaryMode</filePath> </levelVariant> <levelVariant> <filePath>AmazingMode</filePath> </levelVariant> </config> The XSD, located in "Schemas/config.xsd" relative to the XML file to be validated: <?xml version="1.0" encoding="utf-8" ?> <xs:schema xmlns:xs="http://www.w3.org/2001/XMLSchema" elementFormDefault="qualified"> <xs:element name="config"> <xs:complexType> <xs:sequence> <xs:element name="levelVariant"> <xs:complexType> <xs:sequence> <xs:element name="filePath" type="xs:anyURI"> </xs:element> </xs:sequence> </xs:complexType> </xs:element> </xs:sequence> </xs:complexType> </xs:element> </xs:schema> Right now, I just want to validate the XML file precisely as it appears currently. Once I understand this better, I'll expand more. Do I really need so many lines for something as simple as the XML file as it currently exists? The validation code in C#: public void SetURI(string uri) { XElement toValidate = XElement.Load(Path.Combine(PATH_TO_DATA_DIR, uri) + ".xml"); // begin confusion // exception here string schemaURI = toValidate.Attributes("xmlns").First().ToString() + toValidate.Attributes("xsi:noNamespaceSchemaLocation").First().ToString(); XmlSchemaSet schemas = new XmlSchemaSet(); schemas.Add(null, schemaURI); XDocument toValidateDoc = new XDocument(toValidate); toValidateDoc.Validate(schemas, null); // end confusion root = toValidate; } Running the above code gives this exception: The ':' character, hexadecimal value 0x3A, cannot be included in a name. Any illumination would be appreciated.

  • Why is zIndex not working from IE/Javascript?

    - by Vilx-
    <!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" /> <meta http-equiv="X-UA-Compatible" content="IE=7" /> <title>Problem demo</title> </head> <body> <div style="background:red; position:relative;" id='div1'>1. <div style="background:lime; position: absolute; width: 300px;height: 300px; top: 3px; left: 30px" id="div2">3.</div> </div> <div style="background:blue;position:relative;color: white" id="div3">2.</div> <script type="text/javascript">/*<![CDATA[*/ window.onload= function() { // The container of the absolute DIV document.getElementById('div1').style.zIndex = 800; // The lowest DIV of all which obscures the absolute DIV document.getElementById('div2').style.zIndex = 1; // The absolute DIV document.getElementById('div3').style.zIndex = 1000; } /*]]>*/</script> </body> </html> In a nutshell, this script has two DIV elements with position:relative and the first of them has a third DIV with position:absolute in it. It's all set to run on IE-7 standards mode (I'm targeting IE7 and above). I know about the separate z-stacks of IE, so by default the third DIV should be beneath the second DIV. To fix this problem there is some Javascript which sets the z-orders of first and third DIV to 1000, and the z-order of the second DIV to 999. Unfortunately this does not help. If the z-indexes were set in markup, this would work, but why not from JS? Note: This problem does not exist in IE8 standards mode, but I'm targetting IE7, so I can't rely on that. Also, if you save this to your hard drive and then open it up, at first IE complains something about ActiveX and stuff. After you wave it away, everything works as expected. But if you refresh the page, the problem is there again.

  • Emacs enum indentation

    - by Masterofpsi
    I'm having a problem with Emacs's indentation of Java enums. While it indents the first member OK, it wants to give all of the rest of the static enum members an additional level of indentation. It looks like this: class MyClass { public enum MyEnum { ONE(1), //good TWO(2), // not good! THREE(3), FOUR(4); private final int value; } } When I run C-c C-s on the line that opens the enum, it gives me ((inclass 1) (topmost-intro 1)), which doesn't seem quite right -- it seems like it should be giving brace-list-open. When I run it on the first enum member, it gives me ((defun-block-intro 21)), which is definitely not right. Every subsequent member gives (statement-cont 50). I'm in java-mode and I'm using the java style of indentation. Does anyone know what the problem might be?

  • Need help on Coda slider tabs to move inside an overflow:hidden div

    - by Reden
    I'm not too good at javascript. and hope I can get a bit of help. I'm using Coda Slider 2.0, and have designed it to where the tabs are another slider to the right of the main slider, and each item. Basically like this mootools plugin http://landofcoder.com/demo/mootool/lofslidernews/index2.1.html Problem is the items will not scroll. How do I make the items (or tabs to the right) scroll down as the slider rotates? Otherwise the slider will show the 4th slide but not scroll to the 4th item on the right, but Thanks everyone. Here is the Coda-Slider plugin: // when the DOM is ready... $(document).ready(function () { var $panels = $('#slider .scrollContainer > div'); var $container = $('#slider .scrollContainer'); // if false, we'll float all the panels left and fix the width // of the container var horizontal = true; // float the panels left if we're going horizontal if (horizontal) { $panels.css({ 'float' : 'left', 'position' : 'relative' // IE fix to ensure overflow is hidden }); // calculate a new width for the container (so it holds all panels) $container.css('width', $panels[0].offsetWidth * $panels.length); } // collect the scroll object, at the same time apply the hidden overflow // to remove the default scrollbars that will appear var $scroll = $('#slider .scroll').css('overflow', 'hidden'); // apply our left + right buttons $scroll .before('<img class="scrollButtons left" src="images/scroll_left.png" />') .after('<img class="scrollButtons right" src="images/scroll_right.png" />'); // handle nav selection function selectNav() { $(this) .parents('ul:first') .find('a') .removeClass('selected') .end() .end() .addClass('selected'); } $('#slider .navigation').find('a').click(selectNav); // go find the navigation link that has this target and select the nav function trigger(data) { var el = $('#slider .navigation').find('a[href$="' + data.id + '"]').get(0); selectNav.call(el); } if (window.location.hash) { trigger({ id : window.location.hash.substr(1) }); } else { $('ul.navigation a:first').click(); } // offset is used to move to *exactly* the right place, since I'm using // padding on my example, I need to subtract the amount of padding to // the offset. Try removing this to get a good idea of the effect var offset = parseInt((horizontal ? $container.css('paddingTop') : $container.css('paddingLeft')) || 0) * -1; var scrollOptions = { target: $scroll, // the element that has the overflow // can be a selector which will be relative to the target items: $panels, navigation: '.navigation a', // selectors are NOT relative to document, i.e. make sure they're unique prev: 'img.left', next: 'img.right', // allow the scroll effect to run both directions axis: 'xy', onAfter: trigger, // our final callback offset: offset, // duration of the sliding effect duration: 500, // easing - can be used with the easing plugin: // http://gsgd.co.uk/sandbox/jquery/easing/ easing: 'swing' }; // apply serialScroll to the slider - we chose this plugin because it // supports// the indexed next and previous scroll along with hooking // in to our navigation. $('#slider').serialScroll(scrollOptions); // now apply localScroll to hook any other arbitrary links to trigger // the effect $.localScroll(scrollOptions); // finally, if the URL has a hash, move the slider in to position, // setting the duration to 1 because I don't want it to scroll in the // very first page load. We don't always need this, but it ensures // the positioning is absolutely spot on when the pages loads. scrollOptions.duration = 1; $.localScroll.hash(scrollOptions); /////////////////////////////////////////////// // autoscroll /////////////////////////////////////////////// // start to automatically cycle the tabs cycleTimer = setInterval(function () { $scroll.trigger('next'); }, 2000); // how many milliseconds, change this to whatever you like // select some trigger elements to stop the auto-cycle var $stopTriggers = $('#slider .navigation').find('a') // tab headers .add('.scroll') // panel itself .add('.stopscroll') // links to the stop class div .add('.navigation') // links to navigation id for tabs .add("a[href^='#']"); // links to a tab // this is the function that will stop the auto-cycle function stopCycle() { // remove the no longer needed stop triggers clearInterval(cycleTimer); // stop the auto-cycle itself $buttons.show(); // show the navigation buttons document.getElementById('stopscroll').style.display='none'; // hide the stop div document.getElementById('startscroll').style.display='block'; // block the start div } // bind stop cycle function to the click event using namespaces $stopTriggers.bind('click.cycle', stopCycle); /////////////////////////////////////////////// // end autoscroll /////////////////////////////////////////////// // edit to start again /////////////////////////////////////////////// // select some trigger elements to stop the auto-cycle var $startTriggers_start = $('#slider .navigation').find('a') // tab headers .add('.startscroll'); // links to the start class div // this is the function that will stop the auto-cycle function startCycle() { // remove the no longer needed stop triggers $buttons.hide(); // show the navigation buttons $scroll.trigger('next'); // directly to the next first cycleTimer = setInterval(function () { // now set timer again $scroll.trigger('next'); }, 5000); // how many milliseconds, change this to whatever you like document.getElementById('stopscroll').style.display='block'; // block the stop div document.getElementById('startscroll').style.display='none'; // hide the start div } // bind stop cycle function to the click event using namespaces $startTriggers_start.bind('click.cycle', startCycle); /////////////////////////////////////////////// // end edit to start /////////////////////////////////////////////// });

  • ASP.Net Cross Page Posting

    - by John
    Currently I have two pages: The first page contains an input form, and the 2nd page generates an excel document. The input form's button posts to this 2nd page. What I'd like to do is add a second button which also posts to the 2nd page; however, I'll need requests created from this new button to act differently, which brings me to my question: Is there a way I can tell, from the 2nd page, which button was pressed to submit the request? The main reason I'm asking is I'd like to re-use the 2nd page's logic in parsing the information from the first page if possible; I'd rather not have to copy it to a new page and have the new button post to that. Thanks!

  • Powershell $LastExitCode=0 but $?=False . Redirecting stderr to stdout gives NativeCommandError

    - by Colonel Panic
    Can anyone explain Powershell's surprising behaviour in the second example below? First, a example of sane behaviour: PS C:\> & cmd /c "echo Hello from standard error 1>&2"; echo "`$LastExitCode=$LastExitCode and `$?=$?" Hello from standard error $LastExitCode=0 and $?=True No surprises. I print a message to standard error (using cmd's echo). I inspect the variables $? and $LastExitCode. They equal to True and 0 respectively, as expected. However, if I ask Powershell to redirect standard error to standard output over the first command, I get a NativeCommandError: PS C:\> & cmd /c "echo Hello from standard error 1>&2" 2>&1; echo "`$LastExitCode=$LastExitCode and `$?=$?" cmd.exe : Hello from standard error At line:1 char:4 + cmd <<<< /c "echo Hello from standard error 1>&2" 2>&1; echo "`$LastExitCode=$LastExitCode and `$?=$?" + CategoryInfo : NotSpecified: (Hello from standard error :String) [], RemoteException + FullyQualifiedErrorId : NativeCommandError $LastExitCode=0 and $?=False My first question, why the NativeCommandError ? Secondly, why is $? False when cmd ran successfully and $LastExitCode is 0? Powershell's docs about_Automatic_Variables don't explicitly define $?. I always supposed it is True if and only if $LastExitCode is 0 but my example contradicts that. Here's how I came across this behaviour in the real-world (simplified). It really is FUBAR. I was calling one Powershell script from another. The inner script: cmd /c "echo Hello from standard error 1>&2" if (! $?) { echo "Job failed. Sending email.." exit 1 } # do something else Running this simply .\job.ps1, it works fine, no email is sent. However, I was calling it from another Powershell script, logging to a file .\job.ps1 2>&1 > log.txt. In this case, an email is sent! Here, the act of observing a phenomenon changes its outcome. This feels like quantum physics rather than scripting! [Interestingly: .\job.ps1 2>&1 may or not blow up depending on where you run it]

  • How much should I charge for Rails programming?

    - by Oskar Gantt
    I have been asked to quote an hourly rate for freelance programming for a Rails project. Although it would be my first paid project on Rails, I know the technology well from personal projects and have a decade of professional programming experience. This would be my first freelance project ever, so I have no idea how to find out what the going rate for my services should be. Obviously, if I quote a rate that is too high, they may choose someone else - too low and I may feel cheated later on. Any suggestions? Update: I am in NYC and the project is scheduled for 6 months to a year (but this seems unrealistic - I think it will be a multi-year project). I would develop on site (at a corporate location) with one other developer and the project would consist of about 200 custom-built pages initially. 10 hour days with weekends and additional overtime as required. The customer has given no information about how much they will pay - "a competitive rate" - they want me to start the discussion.

  • Setting the initial value of a property when using DataContractSerializer

    - by Eric
    If I am serializing and later deserializing a class using DataContractSerializer how can I control the initial values of properties that were not serialized? Consider the Person class below. Its data contract is set to serialize the FirstName and LastName properties but not the IsNew property. I want IsNew to initialize to TRUE whether a new Person is being instantiate as a new instance or being deserialized from a file. This is easy to do through the constructor, but as I understand it DataContractSerializer does not call the constructor as they could require parameters. [DataContract(Name="Person")] public class Person { [DataMember(Name="FirstName")] public string FirstName { get; set; } [DataMember(Name = "LastName")] public string LastName { get; set; } public bool IsNew { get; set; } public Person(string first, string last) { this.FirstName = first; this.LastName = last; this.IsNew = true; } }

  • CSS border and the :hover dynamic pseudo-class

    - by dbasch
    Hi All, I have built a persistent dropline menu with two levels using only CSS. It is pretty standard. It is a nested set of UL's and the UL's :hover state is what shows and hides the sub menu levels. Something like this: | *Pets* | Colors | Cars | | Cats | Dogs | Birds| Goats | Sheep | | Pets | *Colors* | Cars | | Red | Orange | Green | Blue| Yellow | I then added a 1px border at the bottom of the first level UL element. Like this: | *Pets* | Colors | Cars | -------------------------------------- | Cats | Dogs | Birds| Goats | Sheep | When I hover over a first level item (Pets), and then move the mouse down to the second level (Cats), the entire second level disappears. I finally figured out that the UL's 1px border is not included in the hover area for the UL. Can I add a border to the bottom of a dropline menu level without messing up the menu hovering? Thanks!

  • What's the (hidden) cost of lazy val? (Scala)

    - by Jesper
    One handy feature of Scala is lazy val, where the evaluation of a val is delayed until it's necessary (at first access). Ofcourse a lazy val must have some overhead - somewhere Scala must keep track of whether the value has already been evaluated and the evaluation must be synchronized, because multiple threads might try to access the value for the first time at the same time. What exactly is the cost of a lazy val - is there a hidden boolean flag associated with a lazy val to keep track if it has been evaluated or not, what exactly is synchronized and are there any more costs? And a follow-up question: Suppose I do this: class Something { lazy val (x, y) = { ... } } Is this the same as having two separate lazy vals x and y or do I get the overhead only once, for the pair (x, y)?
