  • How should I do custom sort in Python 3?

    - by S.Mark
    In Python 2.x, I could pass custom function to sorted and .sort functions >>> x=['kar','htar','har','ar'] >>> >>> sorted(x) ['ar', 'har', 'htar', 'kar'] >>> >>> sorted(x,cmp=customsort) ['kar', 'htar', 'har', 'ar'] Because, in My language, consonents are comes with this order "k","kh",....,"ht",..."h",...,"a" But In Python 3.x, looks like I could not pass cmp keyword >>> sorted(x,cmp=customsort) Traceback (most recent call last): File "<stdin>", line 1, in <module> TypeError: 'cmp' is an invalid keyword argument for this function Is there any alternatives or should I write my own sorted function too?

  • How to get Jquery form plugin and Jquery validation to work together.

    - by Matthew
    Hello guys, I was hoping someone can shed some light on what might be occurring on my page. Okay what I currently have on my page is a simple form that collects first name, last name, city, state and email. Once submitted it will hit a PHP page that updates our DB and echo's back to the designted div with a class of .response. I am using jquery.validation and placing that dynamic function within the submitHandler like so: submitHandler: function(form) { $(form).ajaxSubmit({ target: '.response', // target element(s) to be updated with server response resetForm: true, success: function() { $('#commentform').hide(); $('.response').show(); } }); So what I am getting is a div that is not being populated with the echo from my php file in FF and in IE I am getting the message of thank you but the page is taking me to the update.php script in which I have the form action pointing to. I am not sure what I am missing... Thanks, Matt

  • image hover animate

    - by Ryan Max
    Hello. I have the following jQuery script that makes an orange transparent hover effect cover the image when it's rolled over. How do I make it so this script will animate in and out (with a fade?) $(document).ready(function() { $('#gallery a').bind('mouseover', function(){ $(this).parent('li').css({position:'relative'}); var img = $(this).children('img'); $('<div />').text(' ').css({ 'height': img.height(), 'width': img.width(), 'background-color': 'orange', 'position': 'absolute', 'top': 0, 'left': 0, 'opacity': 0.5 }).bind('mouseout', function(){ $(this).remove(); }).insertAfter(this); }); });

  • Run JavaScript after a DropDownList is DataBound

    - by Daniel Coffman
    I need to trigger a JavaScript function to be called AFTER a DropDownList on my ASP.NET WebForms page is DataBound, because the SelectedIndex of this DropDownList is the parameter to the JavaScript function. I've tried this various ways, but it seems that if I do it with pure JavaScript onload by using ClientScript.RegisterStartUpScript, the control can be found (because it hasn't been assigned a clientID yet?). If I use jQuery (document).ready { } it says that the DropDownList has no selectedIndex.value. So I need some JavaScript to run AFTER the control has a value set by the DataBind. How can I accomplish this? onChanged won't work because I need the function to fire on the first page load, with no user input. DataBinding the SelectedIndex of the DropDownList doesn't cause the JavaScript onChanged event to fire.

  • Javascript ajax asynchronous question...

    - by Polaris878
    Hello, I'm wondering if anyone can help me understand some asynchronous javascript concepts... Say I make an asynch ajax call like so: xmlhttp=new XMLHttpRequest(); xmlhttp.onreadystatechange= myFoo; xmlhttp.open("GET",url,true); Here is my callback function: function myFoo() { if (xmlhttp.readyState==4) { if (xmlhttp.status==200) { // Success message } else { // some error message } } } Now, where and when does the execution path start again? Once I make the call to open(), does execution continue directly below the open() and another "thread" enters the asynch function once the ajax request has been completed? Or, does the browser wait for the request to complete, make the Asynch call, and then execution continues right after the open? Thanks!

  • spl_object_hash for PHP < 5.2 (unique ID for object instances)

    - by Rowan
    I'm trying to get unique IDs for object instances in PHP 5+. The function, spl_object_hash() is available from PHP 5.2 but I'm wondering if there's a workaround for older versions. There are a couple of functions in the comments on php.net but they're not working for me. The first (simplified): function spl_object_hash($object){ if (is_object($object)){ return md5((string)$object); } return null; } does not work with native objects (such as DOMDocument), and the second: function spl_object_hash($object){ if (is_object($object)){ ob_start(); var_dump($object); $dump = ob_get_contents(); ob_end_clean(); if (preg_match('/^object\(([a-z0-9_]+)\)\#(\d)+/i', $dump, $match)) { return md5($match[1] . $match[2]); } } return null; } looks like it could be a major performance buster! Does anybody have anything up their sleeve?

  • Using PHP variables inside SQL statements?

    - by Homer
    For some reason I can't pass a var inside a mysql statement. I have a function that can be used for multiple tables. So instead of repeating the code I want to change the table that is selected from like so, function show_all_records($table_name) { mysql_query("SELECT * FROM $table_name"); etc, etc... } And to call the function I use show_all_records("some_table") or show_all_records("some_other_table") depending on which table I want to select from at the moment. But it's not working, is this because variables can't be passed through mysql statements?

  • iPhone: UIImageView not showing images

    - by George
    Hello, I've got UIImageView drawn in my nib-file and it's connected to a imageView iboutlet. I can load single pictures which will show up very nicely, but when it comes to drawing many images separately as like an animation, images won't show. I've got drawImage() function which takes NSData-objects(image data) and draws it to a screen(imageView). Main function has got for loop which loops 300 times as quickly as it can and each time it calls that drawImage function and passes different image data to it. Sometimes when I execute this code, last picture from that "animation" shows up, sometimes not at all. Maybe I need to schedule enough time for imageView so that the image can be shown? Hope someone has some clues. Thanks in advance!

  • Making element draggable with Android WebView (ideally, just with Javascript) ?

    - by GJTorikian
    I'm building an app with a build target of 1.5 . I have a variable, WebView browser, that is calling loadUrl to load a static HTML page from my assets folder. In that HTML page, the following JavaScript is defined: var supportsTouch = ('createTouch' in document); ... var w = $('wrapper'); w[supportsTouch ? 'touchmove' : 'onmousemove'] = move; w[supportsTouch ? 'touchend' : 'onmouseup'] = function(event){ dragging = false; }; where move is another function that handles the dragging. Unfortunately, this doesn't seem to work. I cannot figure out a concise list of which touch events are available to Android--is it ontouchmove, or touchmove? Am I supposed to set up an onTouchEvent call back in my Java code, which then launches the JavaScript function?

  • Communicate between content script and options page

    - by Gaurang Tandon
    I have seen many questions already and all are about background page to content script. Summary My extension has an options page, and a content script. The content script handles the storage functionality (chrome.storage manipulation). Whenever, a user changes a setting in the options page, I want to send a message to the content script to store the new data. My code: options.js var data = "abcd"; // let data chrome.tabs.query({ active: true, currentWindow: true }, function (tabs) { chrome.tabs.sendMessage(tabs[0].id, "storeData:" + data, function(response){ console.log(response); // gives undefined :( }); }); content script js chrome.runtime.onMessage.addListener(function(request, sender, sendResponse) { // not working }); My question: Why isn't the approach not working? Is there any other (better) approach for this procedure.

How can I define: $ = jQuery?

  • Flash Hates Me. Error #1009: Cannot access a property or method of a null object reference

    - by sol
    I simply create a movie clip, put it on the stage and give it an instance name of char. Here's my document class, simple as can be: public class Test extends MovieClip { public function Test() { char.x = 1315; char.y = 459; addEventListener(Event.ENTER_FRAME, mouseListen); } private function mouseListen(e:Event) { char.x = mouseX; char.y = mouseY; } } And I get this error: TypeError: Error #1009: Cannot access a property or method of a null object reference. at com.me::Test/::mouseListen() How in the world is it possible that it knows what "char" is in the constructor but not in the mouseListen function? What else could it be?

  • PhoneGap's vibrate() and beep() functions break in iPhone, Android emulators

    - by Steve Nay
    I have a PhoneGap app that I'm testing on webOS, Android, and iPhone. I'm using physical devices as well as emulators (the ones that come with their respective SDKs, not the PhoneGap emulator). Part of the code uses the navigator.notification.vibrate() and navigator.notification.beep() functions. All the physical devices I'm using either perform the behavior or ignore it if they're not capable (e.g., the iPod can't vibrate). However, the emulators behave differently. The Android emulator kills the app whenever the beep() function is called. The iPhone emulator causes the app to hang whenever the vibrate() function is called. Is there any way to get the emulators to ignore those function calls when they are unable to execute them? That is, is there a way to get them to degrade gracefully so I can test the app both places without having to modify the code specifically for the emulators?

  • jQuery live change problem

    - by Milos
    When I click an element from list, jQuery get class from clicked element and write it in input field. Then value from input need to be written in div#content without any action. HTML: <ul> <li class="NewYork">New York</li> <li class="Paris">Paris</li> <li class="Moscow">Moscow</li> </ul> <input type="text" id="city" value="" /> <div id="content"></div> jQuery: $(document).ready(function() { $('ul li').live('click', function() { var select_value = $(this).attr('class'); $('input#city').val(select_value); return false; }); $('input#city').live('change', function() { var content = $(this).val(); $('#content').text(content+' is beautiful city'); }); });

  • Modifying all HTTP requests on iPhoneOS with MobileSubstrate?

    - by Yifan
    I want to write a MobileSubstrate (http://www.iphonedevwiki.net/index.php/MobileSubstrate) addon that takes every HTTP request and modifies the URL. (The reason is very complicated and would take a while to explain, so just trust me that there's not an alternative). Basically, I need to know what's the best Objective-C message or C function that I should overwrite to intercept any HTTP request, modify the URL, and send the request back to the original function (this shouldn't be just the first request sent by an application, but any redirects too). I think it may be in NSURL or CFNetwork, but am not sure where exactly. This function should, when replaced, work with any apps and the OS itself.

  • Why does an onclick property set with setAttribute fail to work in IE?

    - by Aeon
    Ran into this problem today, posting in case someone else has the same issue. var execBtn = document.createElement('input'); execBtn.setAttribute("type", "button"); execBtn.setAttribute("id", "execBtn"); execBtn.setAttribute("value", "Execute"); execBtn.setAttribute("onclick", "runCommand();"); Turns out to get IE to run an onclick on a dynamically generated element, we can't use setAttribute. Instead, we need to set the onclick property on the object with an anonymous function wrapping the code we want to run. execBtn.onclick = function() { runCommand() }; BAD IDEAS: You can do execBtn.setAttribute("onclick", function() { runCommand() }); but it will break in IE in non-standards mode according to @scunliffe. You can't do this at all execBtn.setAttribute("onclick", runCommand() ); because it executes immediately, and sets the result of runCommand() to be the onClick attribute value, nor can you do execBtn.setAttribute("onclick", runCommand);

  • jQuery AJAX converting variable string to html styled text

    - by sadmicrowave
    I've got an AJAX transmission of a variable string in my primary coding language (Visual FoxPro 9) that looks like this: AjaxResponse = CREATEOBJECT("Custom") lcMessage = "<li class='hello'>Hello</li>" AjaxResponse.AddProperty("Reply", lcMessage) Response.ContentType = "text/html" Response.Write(AjaxResponse.Reply) While using the jQuery function .ajax() I've created a success: function that looks like this: $.ajax({ url: 'index?Proc=GetUuserHistory', dataType: "html", success: function(data){ $("div#history-text").text(data); }; }); My problem is that the text inserting into 'div#history-text' is unformatted and contains the li tags still. I've tried substituting the .text for .prepend, .append, and .html with no luck...is there a way to convert this string back to html format after its been received using Ajax?

  • Accessing HTML 5 Video Progress Event with jQuery

    - by jnolte
    Hello All, The below is for an HTML5 video player event. My partner and I have been stumped for a very large portion of the day on this issue and hope someone can lend some insight on the issue. We have been able to access the progress event with plain js as seen below but when trying to access this with jQuery we get undefined in console. Any help/ recommendations are greatly appreciated. //JS - Works like a charm document.addEventListener("DOMContentLoaded", init, false); function init() { var v = document.getElementById('test-vid'); console.log(v) v.addEventListener('progress', progress, false); } function progress(e) { console.log(e.lengthComputable + ' ' + e.total + ' ' + e.loaded); } // jQuery - NO BUENO - Undefined rendered in console var vid = $('#test-vid'); $(vid).bind("progress", function(e){ console.log(e.total + ' ' + e.loaded + ' ' + e.lengthComputable ); }); Thanks in advance, JN

  • Jquery live not working in IE

    - by Kaskade
    Hi, I have some code that works fine in FF but not in IE. I have read other posts saying that the Jquery live method does not support change events but I am using a click event. Here is my code, it is inside $(document).ready(function(): $("a").live("click", function(e) { alert("link clicked"); //do stuff }); If FF the alert is fired but not in IE. When I use $("a").click it works fine, the problem is that I need to the function to be applied to links that do not exist when the page is first loaded (they will be created via ajax calls at a later stage). Do I have any options here. We are using jquery-1.4.1.min.js. Thanks in advance

  • LINQ DataLoadOptions - Retrieval of data via Fulltext/Broken Foreign Key Relationship

    - by Alex
    I've hit a brick wall: I have an SQL Function: FUNCTION [dbo].[ContactsFTS] (@searchtext nvarchar(4000)) RETURNS TABLE AS RETURN SELECT * FROM Contacts INNER JOIN CONTAINSTABLE(Contacts, *, @searchtext) AS KEY_TBL ON Contacts.Id = KEY_TBL.[KEY] which I am calling via LINQ public IQueryable<ContactsFTSResult> SearchByFullText(String searchText) { return db.ContactsFTS(searchText); } I am projecting the ContactsFTSResult collection into a List<Contact> which is then given to my viewmodel. Here is the problem: My Contacts table (and therefore the Contact object created via LINQ to SQL) has multiple FK relationships to other information, such as Contact.BillingAddressId is an FK to an Address.Id. That information is missing after I do the fulltext search (e.g. if I try to access Contact.BillingAddress it is null). Can I add this information somehow via DataLoadOptions? I tried LoadWith<Contact>(c => c.BillingAddress) but this doesn't work, I assume because of the fact that I'm calling the function instead of doing the whole query via LINQ.

If I move it out it will restore the original background color. Why?

  • Class as an Event Observer

    - by emi
    I want to do something like this... var Color = Class.create({ initialize: function() { this._color = "white"; this.observe("evt: colorChanged", this.colorChanged.bind(this)); }, changeColor: function(color) { this._color = color; this.fire("evt: colorChanged"); }, colorChanged: function(event) { alert("You change my color!"); } }); var a = new Color().changeColor("blue"); Why the colorChange custom event will never be dispatched and I need to use, instead of this, a DOM element like document.observe? In my code I'd like to know which class dispatches the event using event.target and I can't if I must use document or some other DOM element. :( I've been working in Actionscript 3 and that's the methodology I learned to work with custom events in classes. What about Javascript?
