  • Jquery return element html instead of content

    - by jim smith
    I have something like this <ul> <li class="aclass" id="a">content</li> <li class="aclass" id="b">content</li> <li class="aclass" id="c">content</li> <li class="aclass" id="d">content</li> <li class="aclass" id="e">content</li> <li class="aclass" id="f">content</li> </ul> I have code like $(".aclass").live("mousedown",function() { alert($this.html()); }); This will alert the content, what I would like to do is alert the entire element like <li class="aclass" id="f">content</li> I've tried $(this).parent() but that returns the whole UL

  • Write XML File from a flex application back to a rails Server

    - by Markus
    Hi everybody, I have a XML-file, which I want to send to a rails server. To do so I use the following code: <mx:HTTPService id="dataService" result="resultHandler(event)" resultFormat="e4x"/> In a Function triggered by a save button, I do the following: var params:Object = {}; params["xml_file"] = xmlDoc; dataService.method = "POST"; dataService.url = "http://localhost:3000/containers"; dataService.send(params); Unfortunately there is always the Problem (see below) appearing. If I remove the params var, it runs a GET Request... [RPC Fault faultString="HTTP request error" faultCode="Server.Error.Request" faultDetail="Error: [IOErrorEvent type="ioError" bubbles=false cancelable=false eventPhase=2 text="Error #2032: Stream-Fehler. URL: http://localhost:3000/containers"]. URL: http://localhost:3000/containers"] what could be the problem? Thanks for any hints! Markus

  • jQuery: how to handle empty return from getJSON

    - by Gee
    Alright so I have a php script which gets results from a DB, and to get those results I'm using a jQuery script to pull the results via getJSON. It works perfectly but now I want to do something if the php script returns no results (empty). I tried: $.getJSON('path/to/script'), {parameter:parameter}, function(data){ if (data) { alert('Result'); } else { alert('Empty); } }); But it's no good. I've tried different things like if (data.length) but still nothing. I've noticed that if there is no returned data the callback will never fire at all. So if that's the case, how do I handle a empty return?

  • In Birt Reports - Displaying the most common string value in group.

    - by Ben
    For this example data: Index, State, Food 1, CA, Hamburger 2, NY, Lettuce 3, CA, Cheese 4, NY, Lettuce 5, NY, Cheese 6, AR, Cheese I would like to group by State and show the most common food for each state. So the result for the example should be: State, Popular Food CA, Hamburger NY, Lettuce AR, Cheese The problem is I can't find an aggregation that would return the most common string. There is the 'mode' function but it only works on integers. Am I missing Something? Thanks!

  • typeof === "undefined" vs. != null

    - by Thor Thurn
    I often see JavaScript code which checks for undefined parameters etc. this way: if (typeof input !== "undefined") { // do stuff } This seems kind of wasteful, since it involves both a type lookup and a string comparison, not to mention its verbosity. It's needed because 'undefined' could be renamed, though. My question is: How is that code any better than this approach: if (input != null) { // do stuff } As far as I know, you can't redefine null, so it's not going to break unexpectedly. And, because of the type-coercion of the != operator, this checks for both undefined and null... which is often exactly what you want (e.g. for optional function parameters). Yet this form does not seem widespread, and it even causes JSLint to yell at you for using the evil != operator. Why is this considered bad style?

  • Getting a unix timestamp as a string in C++

    - by wyatt
    I'm using the function time() in order to get a timestamp in C++, but, after doing so, I need to convert it to a string. I can't use ctime, as I need the timestamp itself (in its 10 character format). Trouble is, I have no idea what form a time_t variable takes, so I don't know what I'm converting it from. cout handles it, so it must be a string of some description, but I have no idea what. If anyone could help me with this it'd be much appreciated, I'm completely stumped. Alternately, can you provide the output of ctime to a MySQL datetime field and have it interpreted correctly? I'd still appreciate an answer to the first part of my question for understanding's sake, but this would solve my problem.

  • django form creation on init

    - by John
    Hi, How can I add a field in the form init function? e.g. in the code below I want to add a profile field. class StaffForm(forms.ModelForm): def __init__(self, user, *args, **kwargs): if user.pk == 1: self.fields['profile'] = forms.CharField(max_length=200) super(StaffForm, self).__init__(*args, **kwargs) class Meta: model = Staff I know I can add it just below the class StaffForm.... line but I want this to be dynamic depending on what user is passed in so can't do it this way. Thanks

  • ShGetFileInfo called for directory oddity

    - by Axarydax
    Hello, I have a simple file browser and there I display files and folders, obtained by (for directory) SHFILEINFO info = new SHFILEINFO(); SHGetFileInfo(filename, FILE_ATTRIBUTE_DIRECTORY, ref info,Marshal.SizeOf(info), SHGFI_ICON | SHGFI_USEFILEATTRIBUTES | SHGFI_SMALLICON | SHGFI_ADDOVERLAYS); It works 100% fine, but I have noticed an oddity - if I try to obtain an icon for directory, but specify FILE_ATTRIBUTE_NORMAL instead of FILE_ATTRIBUTE_DIRECTORY but it does weird stuff for directories - normal folders have "unknown file type white paper" icons, recycle bin has VLC icon, etc. Directories under SVN have proper overlay, but base file icon (white sheet of paper). I understand that base icon for directory would now be the one of unknown file, but why do some folders have totally strange icon? Config.MSI has installer icon, recycle bin has VLC icon (wtf?!), etc. What does the shell function do with this parameters? Exactly what icon does it obtain? Again, this is not a problem, I'm just curious.

  • How to get the id of Updatepanel which initiated a postback

    - by Voice
    Hi I need to intercept server callback after udate panel async post back and determine which panel initiated the request. The code is pretty simple: Sys.WebForms.PageRequestManager.getInstance().add_pageLoaded(InterceptUpdateCallback); function InterceptUpdateCallback(sender, args) { var updatedPanels = args.get_panelsUpdated(); for (idx = 0; idx < updatedPanels.length; idx++) { if (updatedPanels[idx].id == "myUpdatePanel") { StartSmth(); break; } } } And it works when UpdatePanel is not inside another UpdatePanel. But when it is inside another UpdatePanel updatedPanels[idx].id has parent Updatepanel id. So how can I get the id of UpdatePanel which initiated the request (the inner UpdatePanel)? Thanx

  • C# Generics Casting

    - by Nippysaurus
    Visual sutdio 2008 has the ability to automatically create unit test stubs. I have used this to create some basic unit tests, but I am confused by something: private class bla : BaseStoreItem { // } /// <summary> ///A test for StoreData ///</summary> public void StoreDataTestHelper<T>() where T : BaseStoreItem { FileStore<T> target = new FileStore<T>(); // TODO: Initialize to an appropriate value BaseStoreItem data = new bla(); target.StoreData(data); } [TestMethod()] public void StoreDataTest() { //Assert.Inconclusive("No appropriate type parameter is found to satisfies the type constraint(s) of T. " + // "Please call StoreDataTestHelper<T>() with appropriate type parameters."); StoreDataTestHelper<bla>(); } Why do I get "Error: Cannot convert type 'StorageUnitTests.FileStoreTest.bla' to 'T'" when T is type "bla"? I know "bla" is not a good function name, but its just an example.

  • Jquery UI autocomplete header

    - by Kanaka
    I have a jQuery UI autocomplete (with custom styling) where I added an header. You can see it at work here: http://jsfiddle.net/fbonomi/wJWGV/ the header is added like this: function cComboboxOpen( event) { var s='.... header .....'; $("ul.ui-autocomplete[style*='block']").prepend(s); } it works, and it keeps the column-like form I need (the real data will also be in columns) BUT, I would like to have the header NOT scrolling away when you have a long, scrollable list (e.g if you type "a" in the list) I have seen another very similar question here: jQuery UI Autocomplete with fixed header But it hasn't been answered, and in its current form it does not work properly (the header is "fixed" even when one scrolls the page, for example) How can I avoid the header to scroll away?

  • php include file issue using document root

    - by nithi
    I have used the following code to get the document root. $path = get_file_dir(); function get_file_dir() { global $argv; return realpath($argv[0]); } Below code includes config.php and config.php has the $setuprun variable with a value. if((file_exists("$path/admin/config.php"))) { include_once "$path/admin/config.php"; } if($setuprun=="true") { //do some code } In my system, it takes the document root like /home/myname/myfolder and the variable $setuprun has the value and the code works perfectly. But in another user's system, it shows the following error. Notice: Undefined variable: setuprun in /usr/local/www/chat/setup.php on line 22. He is using FreeBSD 8.2 Stable with MySQL 5, PHP5 and Apache 2.2. Can anyone please help me to solve this error?

  • How to implement "drag n drop" user interface on website?

    - by Nikkeloodeni
    Hello, I was wondering what would be the best way to implement some kind of "drag n drop" user interface? What i mean is that there would be one main page and every link click (eg. other sections like about, gallery, contact form) would open a new drag n drop element on top of that main page. Something like windows desktop where you can move your application windows around the screen. Would it be best to call different functions with AJAX when a link is clicked? Like "gallery" link would call gallery-function and retrieve dynamically generated contents of that "window" with AJAX call and then just load that stuff on some div? Or would some other type of approach suit better for this? I hope I was able to explain this clearly enough. I'm looking for a proper "design pattern" to implement this. All suggestions are wellcome! :)

  • Possible to bind an event listener to a (hypothetical) onChangeInnerHTML event?

    - by DustMason
    In my app, I have an OL tag whose contents are changed by various other dynamic events. Is there some way to put a listener on that OL so that I can execute a function whenever its contents are altered in any way? In this example I need to update a count of items in the list which appears in another spot in the interface. I am using jQuery if that helps. The contents of the OL are being changed with OL.append() and LI.remove(), in case those methods have some special events that I don't know about Thanks!

  • Importing a spreadsheet, but having trouble.

    - by Chris Phelps
    I have a form that allows a user to import a spreadsheet. This spreadsheet is generally static when it comes to column headers, but now the users want to be able to include an optional column (called Notes). My code crashes when I try to read the column from the spreadsheet if it doesn't exist. Dim objCommand As New OleDbCommand() objCommand = ExcelConnection() 'function that opens spreadsheet and returns objCommand Dim reader As OleDbDataReader reader = objCommand.ExecuteReader() While reader.Read() Dim Employee As String = Convert.ToString(reader("User")) Dim SerialNUM As String = Convert.ToString(reader("serialno")) **Dim Notes As String = Convert.ToString(reader("notes"))** If the spreadsheet contains a Notes column, all goes well. If not, crash. How can I check to see if the Notes column exists in the spreadsheet to avoid the crash?

  • library interposition with dlsym

    - by ZeeGeek
    I'm writing an interposition library to track the usage of some library functions in libc, such as open(), close(), connect(), etc. It works generally well on most of the applications. However, when I try it with PHP, using PHP's MySQL module in particular, none of the function calls to libc inside this module is been tracked (so no connect(), no socket(), etc.). 'strace' told me that the system calls socket(), connect(), etc., took place. Running 'file' on the module and libmysqlclient.so.16.0.0 said that they are all dynamically linked. So it shouldn't be a problem caused by static linkage. What might be the problem? I'm using Fedora 11 64-bit version. Thank you.

  • How can I close a SimpleModal dialog when the user clicks the Back button?

    - by Wally Hartshorn
    When a user clicks on a button or link, I use the SimpleModal jQuery plugin to display a dialog to overlay the entire page, preventing the user from clicking another button or link during the delay before the next page loads. (I'd like to avoid this, but that's an issue for another day.) After the next page displays, if the user clicks the Back button, the previous page still has the SimpleModal overlay displayed, preventing them from using the page. This is a problem. How can I cause the SimpleModal dialog to close automatically either when the leaves the page or when the user clicks the Back button to return to the page? I tried this without success: $("body").unload(function() { $.modal.close(); }); Thanks! Wally

  • Extjs 3.4 - Button Icon does not show or does not center

    - by Chris
    I want to fill a button with an icon I created but whatever I have tried just seems to put the icon either half cut off and way left, or it doesn't show at all. I've been trying different combinations of CSS and the icon, iconcls, cls button options. I was following the Ext 3 buttons example page but that doesn't seem to display anything for me... This code is an item inside my form panel (I try to replicate this with different buttons in the panel) { xtype: 'container', layout: { type: 'table', columns: 2, tableAttrs: { cellspacing: 5 } }, // padding: 5, pack: 'center', align: 'middle', items: [{ xtype: 'button', width: 40, // scale: 'medium', ref: '../drawToolsBtn', tooltip: 'Drawing Tools', icon: 'img/draw.png', iconAlign: 'top', baseCls: 'x-plain', // iconCls: 'drawBtn', enableToggle: true, // padding: 3, toggleHandler: function(btn, state) { this.showDrawToolsWin(state); }, scope: this },{ xtype: 'label', // columnWidth: 1, // remainder of container padding: 3, text: 'Click button to open Drawing Tools Menu' }] } CSS -------------------- .drawBtn{ background: url(../img/draw.png) !important; } Thank you for any help!

  • jQuery: move window viewport to show freshly toggled element

    - by k00k
    I have a simple bit of jQuery in doc ready which toggles a div containing a textarea: $('div#addnote-area').hide(); // hide the div $('a#addnote-link').click(function() { // click event listener on link $('div#addnote-area').toggle(); // toggle the hidden div }); The toggle works fine when clicking the link. The problem I'm having is that if div#addnote-area is below the browser's current viewport, it remains there when it's shown. I'd like the user's cursor to go to the textarea and for the whole textarea to be viewable in the window. Click here to see an image for more context

  • Trick to getting initWithNibFile to be invoked?

    - by PhazeZero
    I've implemented a View Controller, and I'm trying to do some very basic initialization in initWithNibFile...which I understand to be the designated initializer for View Controller objects. I've tried to put breakpoints on the code, and have put very simple NSLog statements into it as well. Regardless...I'm not seeing it be executed (and the object i'm attempting to alloc/init inside the function is also not being allocated - so I'm about 99% sure I'm not hitting the code. Is there something I need to do elsewhere to cause this method to be invoked? I'm getting a clean build, no warnings or errors. And the app successfully loads up the View, and I can invoke a ButtonClick method I've coded and connected to this same View Controller. Any suggestions would be appreciated. TC

  • App stays in splash screen in iOS 7.0.3

    - by Sathish
    Recently in iOS 7.0.3, my app stays in the splash screen and was not going into the app at all. If i kill the app, and launch it again it opens up without any issues. Can anyone help me on this issue?. I think the application -didFinishLaunchingWithOptions was not returning yes. Note: I have a lot of stuffs like deleting database, initializing a dozen of buttons in appdelegate's *init* function. I know that it is a bad practice to have things in init but since its been there for more than 4 years and was working fine with previous OS versions i didn't find a good reason to change it. Also this issue is not happening all the time. My app size is 40 MB. Thanks in advance...

  • Sprintf equivalent in Mathematica?

    - by jxy
    I don't know why Wikipedia lists Mathematica as a programming language with printf. I just couldn't find the equivalent in Mathematica. My specific task is to process a list of data files with padded numbers, which I used to do it in bash with fn=$(printf "filename_%05d" $n) The closest function I found in Mathematica is PaddedForm. And after some trial and error, I got it with "filename_" <> PaddedForm[ Round@#, 4, NumberPadding -> {"0", ""} ]& It is very odd that I have to use the number 4 to get the result similar to what I get from "%05d". I don't understand this behavior at all. Can someone explain it to me? And is it the best way to achieve what I used to in bash?

  • MochaUI: 'A is null' when adding columns

    - by Richard John
    I've just downloaded MochaUI, and I'm playing around trying to build an interface. I've successfully created windows, but I'm having trouble when it comes to layouts with columns. I've included all of the libraries in the same order as the demo, and this is in my init code: window.addEvent('domready', function(){ new MochaUI.Column({ id: 'sideColumn1', placement: 'left', width: 200, resizeLimit: [100, 300] }); }); When run, no column is created and I get the error: A is null Does anyone have any ideas? Thanks!

  • IE 8 prompts user on "slow" jQuery script

    - by Jason
    I have a form with over 100 list items that I must reorder on submit. The following code works to reorder my list without any apparent problems in Firefox; however, IE prompts with the message "A script on this page is causing Internet Explorer to run slowly. If it continues to run, your computer may become unresponsive. Do you want to abort the script?" If the user clicks 'No', the script will work as expected. var listitems = $(form).find('li').get(); listitems.sort(function(a, b) { var compA = $(a).attr('id'); var compB = $(b).attr('id'); return (compA - compB); }); Any ideas on how to make this more efficient?
