  • $("body").scrollTop() doesn't update in safari

    - by Kristoffer Nolgren
    I'm working on a website: http://beta.projektopia.se/ the body has several background-images that are updated on scroll like this: $(document).ready(function(){ $(document).scroll(function(){ var scrollfactor=$("body").scrollTop()*0.2; var centerscrollpos =scrollfactor+613; var docheight = $(document).height(); var windowheight = $(window).height(); var bottompos = (docheight-980)-((docheight-windowheight)*0.2)+scrollfactor; var scrollpos = 'center '+scrollfactor+'px,center '+bottompos+'px, center '+ centerscrollpos+'px,center 0px'; $("body").css("background-position", scrollpos); }); }); Lots of calculations, but the important thing is that a scrollpos is created that should change the position of the background when you scroll, to create a parallax-effect. It works great in chrome, but in firefox, the variable scrollfactor, that is suppose to get the current scroll-position, doesn't update. ps, some people have this issue due to lack of correct doctype. I believe i have declared it correctly like this: <!DOCTYPE html>

  • Iframe auto-height not working when page changes in IE

    - by DisgruntledGoat
    I have an iframe in a page, with the following auto-height script. function autoHeight(e) { if ( e.contentDocument ) { e.height = e.contentDocument.body.offsetHeight + 35; } else { e.height = e.contentWindow.document.body.scrollHeight + 35; } } document.domain = "totalstudents.co.uk"; var ifr = document.getElementById('housingdata'); ifr.onload = function() { autoHeight(ifr); } The iframe resizes fine when the outer page is loaded, but when I go to a new page in the iframe, scrollbars appear and the page does not get resized in Internet Explorer. In other browsers the iframe gets resized, because the onload event fires each time. I'm using IE8 but the outer page is setting it to IE7 compatibility mode. Is there a workaround for IE?

  • Rendering of graphics different depending on position

    - by jedierikb
    When drawing parallel vertical lines with a fixed distance between them (1.75 pixels) with a non-integer x-value-offset to both lines, the lines are drawn differently based on the offset. In the picture below are two pairs of very close together vertical lines. As you can see, they look very different. This is frustrating, especially when animating the sprite. Any ideas how ensure that sprites-with-non-integer-positions' graphics will visually display the same? package { import flash.display.Sprite; import flash.display.StageAlign; import flash.display.StageScaleMode; import flash.events.Event; public class tmpa extends Sprite { private var _sp1:Sprite; private var _sp2:Sprite; private var _num:Number; public function tmpa( ):void { stage.align = StageAlign.TOP_LEFT; stage.scaleMode = StageScaleMode.NO_SCALE; _sp1 = new Sprite( ); drawButt( _sp1, 0 ); _sp1.x = 100; _sp1.y = 100; _num = 0; _sp2 = new Sprite( ); drawButt( _sp2, _num ); _sp2.x = 100; _sp2.y = 200; addChild( _sp1 ); addChild( _sp2 ); addEventListener( Event.ENTER_FRAME, efCb, false, 0, true ); } private function efCb( evt:Event ):void { _num += .1; if (_num > 400) { _num = 0; } drawButt( _sp2, _num ); } private function drawButt( sp:Sprite, offset:Number ):void { var px1:Number = 1 + offset; var px2:Number = 2.75 + offset; sp.graphics.clear( ); sp.graphics.lineStyle( 1, 0, 1, true ); sp.graphics.moveTo( px1, 1 ); sp.graphics.lineTo( px1, 100 ); sp.graphics.lineStyle( 1, 0, 1, true ); sp.graphics.moveTo( px2, 1 ); sp.graphics.lineTo( px2, 100 ); } } } edit from original post which thought the problem was tied to the x-position of the sprite.

  • Is the a pattern for iterating over lists held by a class (dynamicly typed OO languages)

    - by Roman A. Taycher
    If I have a class that holds one or several lists is it better to allow other classes to fetch those lists(with a getter) or to implement a doXList/eachXList type method for that list that take a function and call that function on each element of the list contained by that object. I wrote a program that did a ton of this and I hated passing around all these lists sometimes with method in class a calling method in class B to return lists contained in class C, B contains a C or multiple C's (note question is about dynamically typed OO languages languages like ruby or smalltalk) ex. (that came up in my program) on a Person class containing scheduling preferences and a scheduler class needing to access them.

  • How to retrieve the real height of a #div (including overflowed parts)

    - by Toni Michel Caubet
    The same way i use this to detect when user scolled down the whole page: $(window).scroll(function(){ var diff = $(window).scrollTop() + $(window).height() - $(document).height(); if ($(window).scrollTop() == $(document).height() - $(window).height() || (diff < 5 && diff > -5)){ console.log('yay!'); } }); I wanted to do the same inside a dialog, I am trying like this: $('#dialog').dialog(); $('#dialog').scroll(function(){ var scroll = $('#dialog').scrollTop(); var height = $('#dialog ul').outerHeight(true); if(scroll == height){ $('#dialog').css('background','#999'); }else{ console.log('scrolltop is '+scroll+' and height is: '+height); } }) DEMO: http://jsfiddle.net/AgFXz/ The problem i guess is that i am not retrieving the whole #dialog size but the visible (CSS Defined property) size.. How can i know when user scrolled till the end of the dialog's scroll? Thanks!!

  • handle json request in PHP

    - by wo_shi_ni_ba_ba
    When making an ajax call, when contentType is set to application/json instead of the default x-www-form-urlencoded, server side (in PHP) can't get the post parameters. in the following working example, if I set the contentType to "application/json" in the ajax request, PHP $_POST would be empty. why does this happen? How can I handle a request where contentType is application/json properly in PHP? $.ajax({ cache: false, type: "POST", url: "xxx.php", //contentType: "application/json", processData: true, data: {my_params:123}, success: function(res){ }, complete: function(XMLHttpRequest, text_status) { } });

  • Saving JQuery Draggable Sitemap Values Correctly

    - by mdolon
    I am trying to implement Boagworld's Sitemap tutorial, however I am running into difficulty trying to correctly save the child/parent relationships. The HTML is as follows, however populated with other items as well: <input type="hidden" name="sitemap-order" id="sitemap-order" value="" /> <ul id=”sitemap”> <li id="1"> <dl> <dt><a href=”#”>expand/collapse</a> <a href=”#”>Page Title</a></dt> <dd>Text Page</dd> <dd>Published</dd> <dd><a href=”#”>delete</a></dd> </dl> <ul><!–child pages–></ul> </li> </ul> And here is the JQuery code: $('#sitemap li').prepend('<div class="dropzone"></div>'); $('#sitemap li').draggable({ handle: ' > dl', opacity: .8, addClasses: false, helper: 'clone', zIndex: 100 }); var order = ""; $('#sitemap dl, #sitemap .dropzone').droppable({ accept: '#sitemap li', tolerance: 'pointer', drop: function(e, ui) { var li = $(this).parent(); var child = !$(this).hasClass('dropzone'); //If this is our first child, we'll need a ul to drop into. if (child && li.children('ul').length == 0) { li.append('<ul/>'); } //ui.draggable is our reference to the item that's been dragged. if (child) { li.children('ul').append(ui.draggable); }else { li.before(ui.draggable); } //reset our background colours. li.find('dl,.dropzone').css({ backgroundColor: '', backgroundColor: '' }); li.find('.dropzone').css({ height: '8px', margin: '0' }); // THE PROBLEM: var parentid = $(this).parent().attr('id'); menuorder += ui.draggable.attr('id')+'=>'+parentid+','; $("#sitemap-order").val(order); }, over: function() { $(this).filter('dl').css({ backgroundColor: '#ccc' }); $(this).filter('.dropzone').css({ backgroundColor: '#aaa', height: '30px', margin: '5px 0'}); }, out: function() { $(this).filter('dl').css({ backgroundColor: '' }); $(this).filter('.dropzone').css({ backgroundColor: '', height: '8px', margin: '0' }); } }); When moving items into the top-level (without parents), the parentid value I get is of the first list item (the parent container), so I can never remove the parent value and have a top-level item. Is there a no-brainer answer that I'm just not seeing right now? Any help is appreciated.

  • jquery animating different img widths

    - by romeozor
    Hi there, I've been searching for an answer for a long time with no avail, so it's time to ask. I'm trying to use .animate() to change the size of an image once clicked. The first state of the image would be a thumbnail size, which would animate to the image's original size, then to a thumbnail again. The problem is, not all the images have the same "original" size so I need a way to tell one generic function to switch to the current image's original size. This is my current code which loads on $(window).load: $('img[class=resize]').click(function (){ if ($(this).width() != 150) { $(this).animate({width: '150px'}, 400); } else { $(this).animate({width: ''}, 400); } }); Now this obviously doesn't work the way I want it, because .animate() thinks when I say width: '' I want to make the width = 0. Any suggestions how I should go about this?

  • namespacing large javascript like jquery

    - by frenchie
    I have a very large javascript file: it's over 9,000 lines. The code looks like this: var GlobalVar1 = ""; var GlobalVar2 = null; function A() {...} function B(SomeParameter) {...} I'm using the google compiler and the global variables and functions get renamed a,b,c... and there's a good change that there might be some collision later with some outside code. What I want to do is have my code organized like the jquery library where everything is accessible with $. Is there a way to namespace my code so that everything is behind a # character for example. I'd like to have this to call my code: #.GlobalVar #.functionA(SomeParameter) How can I do this? Thanks.

  • [Ruby] How can I randomly iterate through a large Range?

    - by void
    I would like to randomly iterate through a range. Each value will be visited only once and all values will eventually be visited. For example: (0..9).sort_by{rand}.map{|x| f(x)} where f(x) is some function that operates on each value. A Fisher-Yates shuffle could be used to increase efficiency, but this code is sufficient for many purposes. My problem is that sort_by will transform the range into an array, which is not cool because I am working with astronomically large numbers. Ruby will quickly consume a large amount of RAM trying to create a monstrous array. This is also why the following code will not work: tried = {} # store previous attempts bigint = 99**99 bigint.times { x = rand(bigint) redo if tried[x] tried[x] = true f(x) # some function } This code is very naive and quickly runs out of memory as tried obtains more entries. What sort of algorithm can accomplish what I am trying to do?

  • When to delete newly deprecated code?

    - by John
    I spent a month writing an elaborate payment system that handles both credit card payments and electronic fund transfers. My work was used on production server for about a month. I was told recently by the client that he no longer wants to use the electronic fund transfer feature. Because the way I had to interface and communicate with the credit card gateway is drastically different from the electronic fund transfer api (eg. the cc company gives transaction responses immediately after an http request, while the eft company gives transaction responses 5 business days after an http request), I spent a lot of time writing my own API to abstract common function calls like function payment(amount, pay_method,pay_freq) function updateRecurringSchedule(user_id,new_schedule) etc.. Now that the client wants to abandon the EFT feature, all my work for this abstracted payments API is obsolete. I'm deliberating over whether I should scrap my work. Here's my pro vs. con for scrapping it now: PRO 1: Eliminate code bloat PRO 2: New developers do not need to learn MY API. They only need to read the CC company's API PRO 3: Because the EFT company did not handle recurring payment schedules, refunds, and validation, I wrote my own application to do it. Although the CC company's API permitted this functionality, I opted to use mine instead so that I could streamline my code. now that EFT is out of the picture, I can delete all this confusing code and just rely on the CC company's sytsem to manage recurring billing, payment schedules, refunds, validations etc... CON 1: Although I can just delete the EFT code, it still takes time to remove the entire framework consolidates different payment systems. CON 2: with regards to PRO 3, it takes time to build functionality that integrates the payment system more closely with the CC company. CON 3: I feel insecure deleting all this work. I don't think I'll ever use it again. But, for some inexplicable reason, I just don't feel comfortable deleting this work "right now". So my question is, should I delete one month's worth recent development? If yes, should I do it immediately or wait X amount of time before doing so?

Also I'd like to check the server response and perform some actions if the right conditions meet , but I ' m unsure of how and when the server send back the response . My guess is that the response is gotten in a blocking function, or in an asynchronous function . Could you provide code or information on this as well ?

  • Custom business object comparer

    - by gruber
    Hello, I need to implement mechanism that compares two business objects and return the list of differences (past value, new value, isDifferenceBetter). Because not all fields of class has to be compared and one fields need to be compared with different function then the other (sometimes < is better sometimes is better ... ) I figured out that I need to implelemnt custom attribute and give it to each field that has to be compared in this object. This attribute must have: - name - delegate or sth to point to the function which would be applied for comparision (dont know how to do it so far) So could anyone suggest me if its a good idea? Maybe any other ideas. Using attributes I would be able to use refflection to iterate through each field with attribute and invoke needed delegate. thanks for help bye

  • What's void *userData exactly?

    - by mystify
    In a C function declaration, I have seen this parameter definition: void *userData so, what exactly is that? My guess: the void says it can be anything arbitrary, or even nothing. Almost similar to id of objective-c. It just allows to pass in whatever data structure you like. The star in front of userData says, that the argument must be passed in by reference. So when using this stuff in the function body, typically it must be casted and dereferenced. So if I pass in an pointer to SomeClass instance, I would get that like this: SomeClass *myObj = (SomeClass*)userData; In the case I had nothing special to pass along, I would provide NULL as argument. Are my assumptions correct? Or did I get something wrong?
