  • How to Use Images as Navigation with innerfade Slideshow?

    - by Katie
    I am very new to JavaScript and only have the most basic understanding of how it works, so please bear with me. :) I'm using the jquery.innerfade.js script to create a slideshow with fade transitions for a website I'm developing, and I have added navigation buttons (which are set as background-images) that navigate between the “slides”. The navigation buttons have three states: default/off, hover, and on (each state is a separate image). I created a separate JavaScript document to set the buttons to “on” when they are clicked. The “hover” state is achieved through the CSS. Both the slideshow and the navigation buttons work well. There is just one thing I want to add: I would like the appropriate navigation button to display as “on” while the related “slide” is “playing”. Here's the HTML: <div id="mainFeature"> <ul id="theFeature"> <li id="the1feature"><a href="#" name="#promo1"><img src="_images/carousel/promo1.jpg" /></a></li> <li id="the2feature"><a href="#" name="#promo2"><img src="_images/carousel/promo2.jpg" /></a></li> <li id="the3feature"><a href="#" name="#promo3"><img src="_images/carousel/promo3.jpg" /></a></li> </ul> <div id="promonav-con"> <div id="primarypromonav"> <ul class="links"> <li id="the1title" class="promotop"><a rel="1" href="#promo1" class="promo1" id="promo1" onMouseDown="promo1on()"><strong>Botox Cosmetic</strong></a></li> <li id="the2title" class="promotop"><a rel="2" href="#promo2" class="promo2" id="promo2" onMouseDown="promo2on()"><strong>Promo 2</strong></a></li> <li id="the3title" class="promotop"><a rel="3" href="#promo3" class="promo3" id="promo3" onMouseDown="promo3on()"><strong>Promo 3</strong></a></li> </ul> </div> </div> And here is the jquery.innerfade.js, with my changes: (function($) { $.fn.innerfade = function(options) { return this.each(function() { $.innerfade(this, options); }); }; $.innerfade = function(container, options) { var settings = { 'speed': 'normal', 'timeout': 2000, 'containerheight': 'auto', 'runningclass': 'innerfade', 'children': null }; if (options) $.extend(settings, options); if (settings.children === null) var elements = $(container).children(); else var elements = $(container).children(settings.children); if (elements.length > 1) { $(container).css('position', 'relative').css('height', settings.containerheight).addClass(settings.runningclass); for (var i = 0; i < elements.length; i++) { $(elements[i]).css('z-index', String(elements.length-i)).css('position', 'absolute').hide(); }; this.ifchanger = setTimeout(function() { $.innerfade.next(elements, settings, 1, 0); }, settings.timeout); $(elements[0]).show(); } }; $.innerfade.next = function(elements, settings, current, last) { $(elements[last]).fadeOut(settings.speed); $(elements[current]).fadeIn(settings.speed, function() { removeFilter($(this)[0]); }); if ((current + 1) < elements.length) { current = current + 1; last = current - 1; } else { current = 0; last = elements.length - 1; } this.ifchanger = setTimeout((function() { $.innerfade.next(elements, settings, current, last); }), settings.timeout); }; })(jQuery); // **** remove Opacity-Filter in ie **** function removeFilter(element) { if(element.style.removeAttribute){ element.style.removeAttribute('filter'); } } jQuery(document).ready(function() { jQuery('ul#theFeature').innerfade({ speed: 1000, timeout: 7000, containerheight: '291px' }); // jQuery('#mainFeature .links').children('li').children('a').attr('href', 'javascript:void(0);'); jQuery('#mainFeature .links').children('li').children('a').click(function() { clearTimeout(jQuery.innerfade.ifchanger); for(i=1;i<5;i++) { jQuery('#the'+i+'feature').css("display", "none"); //jQuery('#the'+i+'title').children('a').css("background-color","#226478"); } // if(the_widths[(jQuery(this).attr('rel')-1)]==960) { // jQuery("#vic").hide(); // } else { // jQuery("#vic").show(); // } // jQuery('#the'+(jQuery(this).attr('rel'))+'title').css("background-color", "#286a7f"); jQuery('#the'+(jQuery(this).attr('rel'))+'feature').css("display", "block"); clearTimeout(jQuery.innerfade.ifchanger); }); }); And the separate JavaScript that I created: function promo1on() {document.getElementById("promo1").className="promo1on"; document.getElementById("promo2").className="promo2"; document.getElementById("promo2").className="promo2"; } function promo2on() {document.getElementById("promo2").className="promo2on"; document.getElementById("promo1").className="promo1"; document.getElementById("promo3").className="promo3"; } function promo3on() {document.getElementById("promo3").className="promo3on"; document.getElementById("promo1").className="promo1"; document.getElementById("promo2").className="promo2"; } And, finally, the CSS: #mainFeature {float: left; width: 672px; height: 290px; margin: 0 0 9px 0; list-style: none;} #mainFeature li {list-style: none;} #mainFeature #theFeature {margin: 0; padding: 0; position: relative;} #mainFeature #theFeature li {position: absolute; top: 0; left: 0;} #promonav-con {width: 463px; height: 26px; padding: 0; margin: 0; position: absolute; z-index: 900; top: 407px; left: 283px;} #primarypromonav {padding: 0; margin: 0;} #mainFeature .links {padding: 0; margin: 0; list-style: none; position: relative; font-family: arial, verdana, sans-serif; width: 463px; height: 26px;} #mainFeature .links li.promotop {list-style: none; display: block; float: left; display: inline; margin: 0; padding: 0;} #mainFeature .links li a {display: block; float: left; display: inline; height: 26px; text-decoration: none; margin: 0; padding: 0; cursor: pointer;} #mainFeature .links li a strong {margin-left: -9999px;} #mainFeature .links li a.promo1 {background: url(../_images/carouselnav/promo1.gif); width: 155px;} #mainFeature .links li:hover a.promo1 {background: url(../_images/carouselnav/promo1_hover.gif); width: 155px;} #mainFeature .links li a.promo1:hover {background: url(../_images/carouselnav/promo1_hover.gif); width: 155px;} .promo1on {background: url(../_images/carouselnav/promo1_on.gif); width: 155px;} #mainFeature .links li a.promo2 {background: url(../_images/carouselnav/promo2.gif); width: 153px;} #mainFeature .links li:hover a.promo2 {background: url(../_images/carouselnav/promo2_hover.gif); width: 153px;} #mainFeature .links li a.promo2:hover {background: url(../_images/carouselnav/promo2_hover.gif); width: 153px;} .promo2on {background: url(../_images/carouselnav/promo2_on.gif); width: 153px;} #mainFeature .links li a.promo3 {background: url(../_images/carouselnav/promo3.gif); width: 155px;} #mainFeature .links li:hover a.promo3 {background: url(../_images/carouselnav/promo3_hover.gif); width: 155px;} #mainFeature .links li a.promo3:hover {background: url(../_images/carouselnav/promo3_hover.gif); width: 155px;} .promo3on {background: url(../_images/carouselnav/promo3_on.gif); width: 155px;} Hopefully this makes sense! Again, I'm very new to JavaScript/JQuery, so I apologize if this is a mess. I'm very grateful for any suggestions. Thanks!

  • How to implement "circular side-scrolling" in my game?

    - by Mr.Gando
    I'm developing a game, a big part of this game, is about scrolling a "circular" background ( the right end of the Background Image can connect with the left start of the Background image ). Should be something like this: ( Entity moving and arrow to show where the background should start to repeat ) This happens in order to allow to have an Entity walking, and the background repeating itself over and over again. I'm not working with tile-maps, the background is a simple Texture (400x300 px). Could anyone point me to a link , or tell me the best way I could accomplish this ? Thanks a lot.

  • How can I instantiate a base class and then convert it to a derived class?

    - by Eric
    I was wondering how to do this, consider the following classes public class Fruit { public string Name { get; set; } public Color Color { get; set; } } public class Apple : Fruit { public Apple() { } } How can I instantiate a new fruit but upcast to Apple, is there a way to instantiate a bunch of Fruit and make them apples with the name & color set. Do I need to manually deep copy? Of course this fails Fruit a = new Fruit(); a.Name = "FirstApple"; a.Color = Color.Red; Apple wa = a as Apple; System.Diagnostics.Debug.Print("Apple name: " + wa.Name); Do I need to pass in a Fruit to the AppleCTor and manually set the name and color( or 1-n properties) Is there an better design to do this?

  • How do I execute a shell-command in background?

Here's a script I'm running if it might be of help: bk-konsoles.bash

  • How to use custom color for each textview in listview that extends SimpleAdapter in Android ?

    - by mob-king
    I have a listview with custom rows and that extends SimpleAdapter. Each row consist of two linear layouts : 1st having two textviews of which one is hidden in horizontal orientation, second having two textviews in horizontal orientation. Now depending on the value in hidden textview , I want to setcolor for the remaining items for the row. To put it as simple: each listview item has some custom colors the value of which comes from the hidden field. I have done this by overriding getview() for the simpleadapter and returning view for each, but this makes list very slow to render (and that I think is obvious as so much of work for each view before showing it). Can I do this in some more efficient way ? like making views and then add up to list instead of using xml layout maybe one solution OR any other ? Any help ? Thanks.

  • Can I update an iOS Enterprise App in the background like an App Store app can?

    - by lehn0058
    I have an iOS enterprise app that we are wirelessly distributing to our devices. Currently the app polls our server once a day to see if there is an app update. If there is, we try to install it by having the app call the following code: NSURL *installUrl = [NSURL URLWithString:[NSString stringWithFormat:@"itms-services://?action=download-manifest&url=%@", plistUrl]]; [[UIApplication sharedApplication] openURL:installUrl]; This causes the app to prompt the user with an alert dialog to install the update. If they click install, the app closes and the update is downloaded and installed. I am wondering if there is anything for enterprise apps for iOS 7 similar to the AppStore's automatic updates? I would like to be able to update our app without the user having to press an update button and be able to update at a time when the user won't have to wait for it to install.

  • Cocoa accessibility API, can I click a window in the background without activating it?

    - by Winawer
    I've been searching forever for a solution to this, so I thought I'd seek out the brainpower of greater minds than mine. I'm developing a Cocoa app that uses the Accessibility API to manipulate another program (it's a hotkey app). The app I'm controlling typically has multiple windows open, with some hidden behind others. What I would like to do, if it's possible, is to send mouse events to windows using the Accessibility API in a way that presses a button in the window without bringing it to the foreground (interact with the window but don't activate it). The reason I'm trying to do this is that sending the mouse event to this other window will force it to the foreground and disrupt the user's interaction with the foremost window. This is possible on Windows - apparently, because apps similar to mine do it there - but I'm getting the feeling that this isn't possible with Cocoa, given the way the window manager works. Am I mistaken?

  • XSLT Transforming sequential XML to hierarchical XML

    - by Jean-Paul Smit
    I have a requirement to transform a sequential XML node list into a hierarchical, but I run into some XSLT specific knowledge gap. The input XML contains articles, colors and sizes. In the sample below 'Record1' is an article, 'Record2' represents a color and 'Record3' are the sizes. The number of colors and sizes (record2 and record3) elements can vary. <root> <Record1>...</Record1> <Record2>...</Record2> <Record3>...</Record3> <Record3>...</Record3> <Record2>...</Record2> <Record3>...</Record3> <Record3>...</Record3> <Record3>...</Record3> <Record3>...</Record3> <Record1>...</Record1> <Record2>...</Record2> <Record3>...</Record3> <Record3>...</Record3> <Record2>...</Record2> <Record3>...</Record3> <Record3>...</Record3> <Record3>...</Record3> <Record3>...</Record3> </root> All fields are on the same hierarchical level, but still I have to create this structure as output: <root> <article> -> Record1 <color> -> Record2 <size>...</size> -> Record3 <size>...</size> -> Record3 </color> <color> -> Record2 <size>...</size> -> Record3 <size>...</size> -> Record3 <size>...</size> -> Record3 <size>...</size> -> Record3 </color> </article> <article> -> Record1 <color> -> Record2 <size>...</size> -> Record3 <size>...</size> -> Record3 </color> <color> -> Record2 <size>...</size> -> Record3 <size>...</size> -> Record3 <size>...</size> -> Record3 <size>...</size> -> Record3 </color> </article> </root> I've tried to iterate the nodes sequentially but for example the 'article' (=record1) node tag needs to remain unclosed while 'color' (=record2) nodes are processed. The same counts for processing 'size' (=record3) having 'color' unclosed, but that is not allowed by XSLT. My next idea was to call a template for every article, color and size level, but I don't know how to select for example all 'record3' nodes between the current 'record2' and the next article represented by 'record1'. I've also got a limitation on the XSLT version because I need this transformation in BizTalk Server which only supports XSLT 1.0 Can someone push me in the right direction?

  • How to allow click-through and a cursor in a background app while not taking the active appearance a

    - by Peter Hosey
    Here are my goals: My application displays an overlay window above all applications' window. The user can draw in the overlay window. The mouse cursor changes to a specific cursor while in the overlay window. The application that has the active appearance before summoning the overlay window still has it while the overlay window is up and usable. The user does not need to click on the overlay window to activate it before they can draw. Drawing in the window does not steal the active appearance away from the application that has it. With LSUIElement, I get #1, #2, #3, and #5. With LSBackgroundOnly, I get #1, #2, #4, and #6. How can I satisify all of these goals without installing an event tap and processing the mouse events myself? Things I've tried: [NSApp preventWindowOrdering] in mouseDown: [NSApp activateIgnoringOtherApps:YES] in applicationWillFinishLaunching: [myWindow orderFront:nil] in applicationWillFinishLaunching: [myWindow makeKeyAndOrderFront:nil] in applicationWillFinishLaunching: [myWindow orderFrontRegardless] in applicationWillFinishLaunching: [myWindow makeMainWindow] in applicationWillFinishLaunching: (this caused failure of point 4 even with LSBackgroundOnly) SetThemeCursor in applicationWillFinishLaunching: (With LSUIElement) Implementing canBecomeMainWindow in my NSPanel subclass to return NO Except where otherwise noted, none of these made any difference. So, with LSUIElement, goals #4 and #6 remain; with LSBackgroundOnly, goals #3 and #5 remain. Any suggestions?

  • Using colon syntax and variables in Sass

    I am still using the old colon syntax (I prefer it more than the bracket syntax) and this particular code: a.button-link +box($main-color) +border-radius(5px) :background :color $main-color :color #fff :padding 5px generates a warning like so: DEPRECATION WARNING: On line 12, character 3 of '/Users/eumir/rails_apps/dxconnect/app/ stylesheets/partials/utilities/_link-styles.sass' Setting properties with = has been deprecated and will be removed in version 3.2. Use "background: $main-color" instead. I tried that but my background color still doesn't show up. Any help on this please? Thanks!

  • What Kind of Knowledge is Necessary For a Permon Who Does Not Have IT Background? [closed]

    - by skyflyer
    One of my colleagues joined our company, which by the way is a internet company, months ago as an on-line marketing specialist. He majored English in his college and has never deeply touched IT before. He says that to be a good on-line marketing specialist he needs to lean some basic IT skills in order to deliver superb work. According to him, things like Search Engine Optimization, monitoring competitors' web sites, design some functionality on web site and so on require IT entree-level knowledge. And he asks me what kind knowledge is helpful for him to do his job. I am stunted by his question. It is easy enough to answer, things like HTML, CSS, even Photo-shop are required in some job descriptions. Also, I believe some basic understanding of dynamic web site, static web site is helpful to him. On the other hand, as a techie I still feel my answer is awkward. What is your opinion on this? Always lot of thanks to you guys on SO.

  • What is the benefit of using int instead of bigint in this case?

  • Blending pixels from Two Bitmaps

    - by MarkPowell
    I'm beating my head against a wall here, and I'm fairly certain I'm doing something stupid, so time to make my stupidity public. I'm trying to take two images, blend them together into a third image using standard blending algorithms (Hardlight, softlight, overlay, multiply, etc). Because Android does not have such blend properties build in, I've gone down the path of taking each pixel and combine them using an algorithm. However, the results are garbage. Any help would be appreciated. Below is the code, which I've tried to strip out all the "junk", but some may have made it through. I'll clean it up if something isn't clear. Bitmap src = BitmapFactory.decodeResource(getResources(), R.drawable.base, options); Bitmap mutableBitmap = src.copy(Bitmap.Config.RGB_565, true); int imageId = getResources().getIdentifier("drawable/" + filter, null, getPackageName()); Bitmap filterBitmap = BitmapFactory.decodeResource(getResources(), imageId, options); float scaleWidth = ((float) mutableBitmap.getWidth()) / filterBitmap.getWidth(); float scaleHeight = ((float) mutableBitmap.getHeight()) / filterBitmap.getHeight(); IntBuffer buffSrc = IntBuffer.allocate(src.getWidth() * src.getHeight()); mutableBitmap.copyPixelsToBuffer(buffSrc); buffSrc.rewind(); IntBuffer buffFilter = IntBuffer.allocate(resizedFilterBitmap.getWidth() * resizedFilterBitmap.getHeight()); resizedFilterBitmap.copyPixelsToBuffer(buffFilter); buffFilter.rewind(); IntBuffer buffOut = IntBuffer.allocate(src.getWidth() * src.getHeight()); buffOut.rewind(); while (buffOut.position() < buffOut.limit()) { int filterInt = buffFilter.get(); int srcInt = buffSrc.get(); int alphaValueFilter = Color.alpha(filterInt); int redValueFilter = Color.red(filterInt); int greenValueFilter = Color.green(filterInt); int blueValueFilter = Color.blue(filterInt); int alphaValueSrc = Color.alpha(srcInt); int redValueSrc = Color.red(srcInt); int greenValueSrc = Color.green(srcInt); int blueValueSrc = Color.blue(srcInt); int alphaValueFinal = convert(alphaValueFilter, alphaValueSrc); int redValueFinal = convert(redValueFilter, redValueSrc); int greenValueFinal = convert(greenValueFilter, greenValueSrc); int blueValueFinal = convert(blueValueFilter, blueValueSrc); int pixel = Color.argb(alphaValueFinal, redValueFinal, greenValueFinal, blueValueFinal); buffOut.put(pixel); } buffOut.rewind(); mutableBitmap.copyPixelsFromBuffer(buffOut); BitmapDrawable drawable = new BitmapDrawable(getResources(), mutableBitmap); imageView.setImageDrawable(drawable); } int convert (int in1, int in2) { //simple multiply for example return in1 * in2 / 255; }

By way of example, I get data for a fruitbowl with an array of fruit objects which in turn contain an array of seeds thus: {"fruitbowl": [{ "name": "apple", "color": "red", "seeds": [] },{ "name": "orange", "color": "orange", "seeds": [ {"size":"small","density":"hard"}, {"size":"small","density":"soft"} ]} } That's all nice and good but down on the client we do stuff with this fruit, like eat it and plant trees... var fruitbowl = [] function Fruit(name, color, seeds){ this.name = name this.color = color this.seeds = seeds this.eat = function(){ // munch munch } } function Seed(size, density){ this.size = size this.density = density this.plant = function(){ // grow grow } } My ajax's success routine currently is currently looping over the thing and constructing each object in turn and it doesn't handle the seeds yet, because before I go looping over seed constructors I'm thinking Is there not a better way? success: function(data){ fruitbowl.length = 0 $.each(data.fruitbowl, function(i, f){ fruitbowl.push(new Fruit(f.name, f.color, f.seeds)) }) I haven't explored looping over the objects as they are and attaching all the methods. Would that work?
