  • question about jQuery droppable/draggable.

    - by FALCONSEYE
    I modified a sample photo manager application. photo manager application Instead of photos, I have employee records coming from a query. My version will let managers mark employees as on vacation, or at work. One of the things I did is to include employee ids like <a href="123">. I get the ids from event.target. This works for the click function but not for the "droppable" function. This is what I have for the click function: $('ul.gallery > li').click(function(ev) { var $item = $(this); var $unid = ev.target; var $target = $(ev.target); if ($target.is('a.ui-icon-suitcase')) { deleteImage($item,$unid); } else if ($target.is('a.ui-icon-arrowreturnthick-1-w')) { recycleImage($item,$unid); } return false; }); ev.target correctly gives the employee id. when i try the same in one of the droppable functions: $gallery.droppable({ accept: '#suitcase li', activeClass: 'custom-state-active', drop: function(ev, ui) { var $unid = ev.target; alert($unid); recycleImage(ui.draggable,$unid); } }); the alert(ui) gives me [object]. What's in this object? How do i get the href out of this? thanks

  • Setting objct literal property value via asynchronous callback.

    - by typeof
    I'm creating a self-contained javascript utility object that detects advanced browser features. Ideally, my object would look something like this: Support = { borderRadius : false, // values returned by functions gradient : false, // i am defining dataURI : true }; My current problem deals with some code I'm adapting from Weston Ruter's site which detects dataURI support. It attempts to use javascript to create an image with a dataURI source, and uses onload/onerror callbacks to check the width/height. Since onload is asynchronous, I lose my scope and returning true/false does not assign true/false to my object. Here is my attempt: Support = { ... dataURI : function(prop) { prop = prop; // keeps in closure for callback var data = new Image(); data.onload = data.onerror = function(){ if(this.width != 1 || this.height != 1) { that = false; } that = true; } data.src = "data:image/gif;base64,R0lGODlhAQABAIAAAAAAAP///ywAAAAAAQABAAACAUwAOw=="; return -1; }(this) }; I'm executing the anonymous function immediately, passing this (which I hoped was a reference to Support.dataURI), but unfortunately references the window object -- so the value is always -1. I can get it to work by using an externally defined function to assign the value after the Support object is created... but I don't think it's very clean that way. Is there a way for it to be self-contained? Can the object literal's function reference the property it's assigned to?

  • How to develop a Jquery plugin to find the first child that match with a selector?

    - by Ivan
    I'm trying to make a Jquery plugin (findFirst()) to find the first child with a given characteristics (something in the middle of the find() and children() functions. For instance, given this markup: <div id="start"> <div> <span>Hello world</span> <ul class="valid-result"> ... </ul> <ul class="valid-result"> <li> <ul class="not-a-result"> ... </ul> </li> </ul> <div> <ul class="valid-result"> ... </ul> </div> </div> </div> If you ask for $("#start").findFirst('ul') it should return all ul lists that I have tagged with the valid-result class, but not the ul with class not-a-result. It is, this function has to find the first elements that matches with a given selector, but not the inner elements that match this selector. This is the first time I try to code a Jquery function, and what I've already read doesn't helps me too much with this. The function I have developed is this: jQuery.fn.findFirst = function (sel) { return this.map(function() { return $(this).children().map(function() { if ($(this).is(sel)) { return $(this); } else { return $(this).findFirst(sel); } }); }); } It works in the sense it tries to return the expected result, but the format it returns the result is very rare for me. I suppose the problem is something I don't understand about Jquery. Here you have the JFiddle where I'm testing. EDIT The expected result after $("#start").findFirst('ul') is a set with all UL that have the class 'valid-result' BUT it's not possible to use this class because it doesn't exist in a real case (it's just to try to explain the result). This is not equivalent to first(), because first returns only one element!

  • How can I pass methods in javascript?

    - by peterjwest
    I often need to pass methods from objects into other objects. However I usually want the method to be attached to the original object (by attached I mean 'this' should refer to the original object). I know a few ways to do this: a) In the object constructor: ObjectA = function() { var that = this; var method = function(a,b,c) { that.abc = a+b+c }} b) In objectA which has been passed objectB: objectB.assign(function(a,b,c) { that.method(a,b,c) }) c) Outside both objects: objectB.assign(function(a,b,c) { objectA.method(a,b,c) }) I want to know if there is a simpler way to pass methods attached to their original objects.

  • Problem Passing Variable to Submit Form in Firefox

    - by George
    In the following example, I have a link that sends a variable to a function which checks if the variable is true and, if so, submits a form on the page. This has been tested and works in IE, Safari, and Chrome, but not Firefox. Trying to figure out what's wrong in Firefox. The function which checks 'action' and then submits form 'login' : function submit(action) { if (action == "submit") { document.login.submit(); } } Link to pass action variable and submit form: <a href="javascript:submit('submit');">SEND FORM</a> When I remove the check and just have the following, it works fine in Firefox: function submit() { document.login.submit(); } <a href="javascript:submit();">SEND FORM</a>

  • Display data requested by an ajax.load() call once complete, not during the call.

    - by niczoom
    My jQuery code (using ajax) request's data from a php script (pgiproxy.php) using the following function: function grabPage($pageURL) { $homepage = file_get_contents($pageURL); echo $homepage; } I then extract the html code i need from the returned data using jQuery and insert it into a div called #BFX, as follows: $("#btnNewLoadMethod1").click(function(){ $('#temp1').load('pgiproxy.php', { data : $("#formdata").serialize(), mode : "graph"} , function() { $('#temp').html( $('#temp1').find('center').html() ); $('#BFX').html( $('#temp').html() ); }); }); This works fine. I get the html data (which is a gif image) i need displayed on screen in the correct div. The problem is i can see the html data loading into the div (dependant on network speed), but what I want is to insert the extracted html code into #BFX ONLY when the ajax request has fully completed.

  • Oracle Unique Indexes

    - by Melvin
    I was creating a new table today in 10g when I noticed an interesting behavior. Here is an example of what I did: CREATE TABLE test_table ( field_1 INTEGER PRIMARY KEY ); Oracle will by default, create a non-null unique index for the primary key. I double checked this. After a quick check, I find a unique index name SYS_C0065645. Everything is working as expected so far. Now I did this: CREATE TABLE test_table ( field_1 INTEGER, CONSTRAINT pk_test_table PRIMARY KEY (field_1) USING INDEX (CREATE INDEX idx_test_table_00 ON test_table (field_1))); After describing my newly created index idx_test_table_00, I see that it is non-unique. I tried to insert duplicate data into the table and was stopped by the primary key constraint, proving that the functionality has not been affected. It seems strange to me that Oracle would allow a non-unique index to be used for a primary key constraint. Why is this allowed?

    I have been looking for an answer for almost a week now, but having read all the stackoverflow items i can't seem to find a solution that is working for me. The error that i'm having is : Port: Could not establish connection. Receiving end does not exist. lastError:30 set lastError:30 dispatchOnDisconnect messaging:277 folder layout : img developer_icon.png js sidebar.js main.js jquery-2.0.3.js manifest.json my the manifest.json file looks something like this (it is version 2) :` "browser_action": { "default_icon": "./img/developer_icon.png" }, "content_scripts": [ { "matches": ["*://*/*"], "js": ["./js/sidebar.js"], "run_at": "document_end" } ], "background" : { "scripts" : ["./js/main.js","./js/jquery-2.0.3.js"] }, I want to handle the user clicking the extension icon so i could inject a sidebar in the existing website (because the extension i would like to develop requires that amount of space). So in main.js : chrome.browserAction.onClicked.addListener(function(tab) { chrome.tabs.getSelected(null, function(tab){ chrome.tabs.sendMessage( //Selected tab id tab.id, //Params inside a object data {callFunction: "toggleSidebar"}, //Optional callback function function(response) { console.log(response); } ); }); }); and in sidebar.js : chrome.runtime.onMessage.addListener(function(req,sender,sendResponse){ console.log("sidebar handling request"); toggleSidebar(); }); but i'm never able to see the console.log in my console because of the error. Does someone know what i did wrong? Thanks in advance!

  • Memory release from local variable in javascript

    - by Bob
    Quick question. I have a js function which gets called on the page every few seconds. It's an ajax update thing. Being a function, I declare local variables. I don't want to use closures or global variables for various reasons. I'd never considered this, but do I need to release/clear the variables at the end of the function to release memory or will js do this for me automatically ? Thanks

  • SSH is looking in the wrong place for the public/private key pair on Windows

    - by Michael Morisy
    I'm trying to configure GIT on my Windows XP machine, but SSH keeps creating and looking for the public/private key pair in non-sensical places, e.g. /.ssh/id_rsa Is there a configuration file in the GIT Installation for Windows where I can switch this to my home directory, or another user defined place? By default, it offers to create new key pairs at //.ssh/id_rsa but that gives me the error "Could not create directory '//.ssh'." And when I'm able to find a directory I can create it in, GIT won't look there.

  • GUI Agent accepts statuses from Daemon and shows it using progress indicator

    - by Pavel
    Hi to all! My application is a GUI agent, which communicate with daemon through the unix domain socket, wrapped in CFSocket.... So there are main loop and added CFRunLoop source. Daemon sends statuses and agent shows it with a progress indicator. When there are any data on socket, callback function begin to work and at this time I have to immediately show the new window with progress indicator and increase counter. //this function initiate the runloop for listening socket - (int) AcceptDaemonConnection:(ConnectionRef)conn { int err = 0; conn->fSockCF = CFSocketCreateWithNative(NULL, (CFSocketNativeHandle) conn->fSockFD, kCFSocketAcceptCallBack, ConnectionGotData, NULL); if (conn->fSockCF == NULL) err = EINVAL; if (err == 0) { conn->fRunLoopSource = CFSocketCreateRunLoopSource(NULL, conn->fSockCF, 0); if (conn->fRunLoopSource == NULL) err = EINVAL; else CFRunLoopAddSource(CFRunLoopGetCurrent(), conn->fRunLoopSource, kCFRunLoopDefaultMode); CFRelease(conn->fRunLoopSource); } return err; } // callback function void ConnectionGotData(CFSocketRef s, CFSocketCallBackType type, CFDataRef address, const void * data, void * info) { #pragma unused(s) #pragma unused(address) #pragma unused(info) assert(type == kCFSocketAcceptCallBack); assert( (int *) data != NULL ); assert( (*(int *) data) != -1 ); TStatusUpdate status; int nativeSocket = *(int *) data; status = [agg AcceptPacket:nativeSocket]; // [stWindow InitNewWindow] inside [agg SendUpdateStatus:status.percent]; } AcceptPacket function receives packet from the socket and trying to show new window with progress indicator. Corresponding function is called, but nothing happens... I think, that I have to make work the main application loop with interrupting CFSocket loop... Or send a notification? No idea....

  • Can't register 32bit dll under 64bit windows

    - by Wodzu
    Hi guys. I try to create a COM object from my JS script like this: function main() { var MyApplication = new ActiveXObject("Base.Application"); } main(); I am getting error: "Automation server can't create object". This error occurs on Windows 2003 64 bit. The dll is 32 bit and it works fine on 32 bit systems. I've tried both versions of Regsvr32.exe on the 64 bit system and both versions told me that dll registered succesfully. Unfortunatelly the error message does not tell me why it can not create object. The reason is unknown, it might be that it can't create object because it is still not registered or it might be something totally different... I've also add full permisions to this dll. I don't know what else I can do, do you have any ideas?

  • PHP - JSON Steam API query

    - by Hunter
    First time using "JSON" and I've just been working away at my dissertation and I'm integrating a few features from the steam API.. now I'm a little bit confused as to how to create arrays. function test_steamAPI() { $api = ('http://api.steampowered.com/ISteamUser/GetPlayerSummaries/v0002/?key='.get_Steam_api().'&steamids=76561197960435530'); $test = decode_url($api); var_dump($test['response']['players'][0]['personaname']['steamid']); } //Function to decode and return the data. function decode_url($url) { $decodeURL = $url; $data = file_get_contents($url); $data_output = json_decode($data, true); return $data_output; } So ea I've wrote a simple method to decode Json as I'll be doing a fair bit.. But just wondering the best way to print out arrays.. I can't for the life of me get it to print more than 1 element without it retunring an error e.g. Warning: Illegal string offset 'steamid' in /opt/lampp/htdocs/lan/lan-includes/scripts/class.steam.php on line 48 string(1) "R" So I can print one element, and if I add another it returns errors. EDIT -- Thanks for help, So this was my solution: function test_steamAPI() { $api = ('http://api.steampowered.com/ISteamUser/GetPlayerSummaries/v0002/?key='.get_Steam_api().'&steamids=76561197960435530,76561197960435530'); $data = decode_url($api); foreach($data ['response']['players'] as $player) { echo "Steam id:" . $player['steamid'] . "\n"; echo "Community visibility :" . $player['communityvisibilitystate'] . "\n"; echo "Player profile" . $player['profileurl'] ."\n"; } } //Function to decode and return the data. function decode_url($url) { $decodeURL = $url; $json = file_get_contents($decodeURL); $data_output = json_decode($json, true); return $data_output; } Worked this out by taking a look at the data.. and a couple json examples, this returns an array based on the Steam API URL (It works for multiple queries.... just FYI) and you can insert loops inside for items etc.. (if anyone searches for this).

  • jquery events on input submit fields

    - by dfilkovi
    I have a problem with jquery submit button onclick and default event. What I want to do is replace an click event on submit button if it has one, and get an dialog box to show up, on clicking yes the dialog should start that default onclick event if submit button has one defined, if it hasn't than the default event should happen (button submits form), .submit() function does not work for me in any case cause I need to send this button also through a form and if button wasn't clicked .submit() sends form data without submit data. Bellow code has a problem, alert('xxx') is always called and it shouldn't, and on clicking yes button alert and dialog creation is called again, also if I remove alert button, I cannot call default submit button event (form submitting with a button). $('input.confirm').each(function() { var input = this; var dialog = document.createElement("div"); $(dialog).html('<p>AREYOUSHURE</p>'); $(input).click(function(event) { event.preventDefault(); var buttons = {}; buttons['NO'] = function() { $(this).dialog("close"); }; buttons['YES'] = function() { $(input).trigger('click'); $(this).dialog("close"); }; $(dialog).dialog( { autoOpen: false, width: 200, modal: true, resizable: false, buttons: buttons }); $(dialog).dialog('open'); return false; }); }); <form method="post" action=""> <input type="hidden" value="1" name="eventId" /> <input type="submit" value="Check" name="checkEvent" class="confirm" onclick="alert('xxx');" /> </form>

  • Having trouble wrapping functions in the linux kernel

    - by Corey Henderson
    I've written a LKM that implements Trusted Path Execution (TPE) into your kernel: https://github.com/cormander/tpe-lkm I run into an occasional kernel OOPS (describe at the end of this question) when I define WRAP_SYSCALLS to 1, and am at my wit's end trying to track it down. A little background: Since the LSM framework doesn't export its symbols, I had to get creative with how I insert the TPE checking into the running kernel. I wrote a find_symbol_address() function that gives me the address of any function I need, and it works very well. I can call functions like this: int (*my_printk)(const char *fmt, ...); my_printk = find_symbol_address("printk"); (*my_printk)("Hello, world!\n"); And it works fine. I use this method to locate the security_file_mmap, security_file_mprotect, and security_bprm_check functions. I then overwrite those functions with an asm jump to my function to do the TPE check. The problem is, the currently loaded LSM will no longer execute the code for it's hook to that function, because it's been totally hijacked. Here is an example of what I do: int tpe_security_bprm_check(struct linux_binprm *bprm) { int ret = 0; if (bprm->file) { ret = tpe_allow_file(bprm->file); if (IS_ERR(ret)) goto out; } #if WRAP_SYSCALLS stop_my_code(&cs_security_bprm_check); ret = cs_security_bprm_check.ptr(bprm); start_my_code(&cs_security_bprm_check); #endif out: return ret; } Notice the section between the #if WRAP_SYSCALLS section (it's defined as 0 by default). If set to 1, the LSM's hook is called because I write the original code back over the asm jump and call that function, but I run into an occasional kernel OOPS with an "invalid opcode": invalid opcode: 0000 [#1] SMP RIP: 0010:[<ffffffff8117b006>] [<ffffffff8117b006>] security_bprm_check+0x6/0x310 I don't know what the issue is. I've tried several different types of locking methods (see the inside of start/stop_my_code for details) to no avail. To trigger the kernel OOPS, write a simple bash while loop that endlessly starts a backgrounded "ls" command. After a minute or so, it'll happen. I'm testing this on a RHEL6 kernel, also works on Ubuntu 10.04 LTS (2.6.32 x86_64). While this method has been the most successful so far, I have tried another method of simply copying the kernel function to a pointer I created with kmalloc but when I try to execute it, I get: kernel tried to execute NX-protected page - exploit attempt? (uid: 0). If anyone can tell me how to kmalloc space and have it marked as executable, that would also help me solve the above problem. Any help is appreciated!

  • Is there a best practice for concatenating MP3 Files, adjusting sample rates to match, while preserving original files?

    - by Scott
    Hello overflow community! Does anyone know if there is a "best practice" to concatenate mp3 files to create new files, while preserving the original files? I am working on a CentOS Linux machine, in command line. I will eventually call the command line from a PHP script. I have been doing research and I have come up with a process that I think could work. It combines general advice from different forums, blogs, and sources like this one. So here I go: Create a temporary folder Loop through files to create a new, converted copy, of file into a "raw" format (which one, I don't know. I didn't know "raw" files existed before too long ago. I could use some suggestions on this) Store the path to the temporary files, in the temporary folder, and then loop through the files to concatenate them and then put the new merged file the final "processed directory" Delete the contents of the temporary file with the temporary raw files inside. Convert the final file from "raw" to mp3 and enjoy the finished result I'm thinking that this course of action might be best because I can't necessarily control the quality of the original "source" mp3s. The only other option I could think of would be to create a script that would perform a similar process upon files being added to the system leaving only the files with the "proper" format and removing the original "erroneous" file. Hopefully you can see that I have put some thought into this and that I'm trying to leverage the collective knowledge of this community to choose the best direction. Perhaps there is a better path that I could take? By concatenate, I mean to join together in sequence to create a new audio file from the "concatenated files."

  • A standard event messaging system with AJAX?

    Is there any standards or messaging framework for AJAX? Right now I have a single page that loads content using Ajax. Because I had a complex form for data entry as part of my content, I need to validate certain events that can occur in my form. So after some adjustments driven by my tests: asyncShould("search customer list click", 3, function() { stop(1000); $('#content').show(); var forCustomerList = newCustomerListRequest(); var forShipAndCharge = newShipAndChargeRequest(forCustomerList); forCustomerList.page = '../../vt/' + forCustomerList.page; forShipAndCharge.page = 'helpers/helper.php'; forShipAndCharge.data = { 'action': 'shipAndCharge', 'DB': '11001' }; var originalComplete = forShipAndCharge.complete; forShipAndCharge.complete = function(xhr, status) { originalComplete(xhr, status); ok($('#customer_edit').is(":visible"), 'Shows customer editor'); $('#search').click(); ok($('#customer_list').is(":visible"), 'Shows customer list'); ok($('#customer_edit').is(":hidden"), 'Does not show customer editor'); start(); }; testController.getContent(forShipAndCharge); }); Here is the controller for getting content: getContent: function (request) { $.ajax({ type: 'GET', url: request.page, dataType: 'json', data: request.data, async: request.async, success: request.success, complete: request.complete }); }, And here is the request event: function newShipAndChargeRequest(serverRequest) { var that = { serverRequest: serverRequest, page: 'nodes/orders/sc.php', data: 'customer_id=-1', complete: errorHandler, success: function(msg) { shipAndChargeHandler(msg); initWhenCustomer(that.serverRequest); }, async: true }; return that; } And here is a success handler: function shipAndChargeHandler(msg) { $('.contentContainer').html(msg.html); if (msg.status == 'flash') { flash(msg.flash); } } And on my server side I end up with a JSON structure that looks like this: $message['status'] = 'success'; $message['data'] = array(); $message['flash'] = ''; $message['html'] = ''; echo json_encode($message); So now loading content consists of two parts: HTML, this is the presentation of the form. DATA, this is any data that needs be loaded for the form FLASH, any validation or server errors STATUS tells client what happened on server. My question is: Is this a valid way to handle event messaging on the client-side or am I going down a path of heartache and pain?

    Hi, I have a sqlite table with following fields: Langauge level hours German 2 50 French 3 40 English 1 60 German 1 10 English 2 50 English 3 60 German 1 20 French 2 40 I want to loop through the records based on language and other conditions and then pass the current selected record to a different function. So I have the following mixture of actual code and psudo code. I need help with converting the psudo code to actual code, please. I am finding it difficult to do so. Here is what I have: Private sub mainp() Dim oslcConnection As New SQLite.SQLiteConnection Dim oslcCommand As SQLite.SQLiteCommand Dim langs() As String = {"German", "French", "English"} Dim i as Integer = 0 oslcConnection.ConnectionString = "Data Source=" & My.Settings.dbFullPath & ";" oslcConnection.Open() oslcCommand = oslcConnection.CreateCommand Do While i <= langs.count If langs(i) = "German" Then oslcCommand.CommandText = "SELECT * FROM table WHERE language = '" & langs(i) & "';" For each record selected 'psudo code If level = 1 Then 'psudo code update level to 2 'psudo code minorp(currentRecord) 'psudo code: calling minorp function and passing the whole record as a parameter End If 'psudo code If level = 2 Then 'psudo code update level to 3 'psudo code minorp(currentRecord) 'psudo code: calling minorp function and passing the whole record as a parameter End If 'psudo code Next 'psudo code End If If langs(i) = "French" Then oslcCommand.CommandText = "SELECT * FROM table WHERE language = '" & langs(i) & "';" For each record selected 'psudo code If level = 1 Then 'psudo code update level to 2 'psudo code minorp(currentRecord) 'psudo code: calling minorp function and passing the whole record as a parameter End If 'psudo code If level = 2 Then 'psudo code update level to 3 'psudo code minorp(currentRecord) 'psudo code: calling minorp function and passing the whole record as a parameter End If 'psudo code Next 'psudo code End If Loop End Sub Many thanks for your help.
