  • Division of text follow the cursor via Javascript/Jquery

    - by webzide
    Dear experts, I wanted have a dynamic division of content follow you with the cursor in the web browser space. I am not a pro at JS so I spent 2 hours to finally debugged a very stupid way to accomplish this. $(document).ready(function () { function func(evt) { var evt = (evt) ? evt : event; var div = document.createElement('div'); div.style.position = "absolute"; div.style.left = evt.clientX + "px"; div.style.top = evt.clientY + "px"; $(div).attr("id", "current") div.innerHTML = "CURSOR FOLLOW TEXT"; $(this).append($(div)); $(this).unbind() $(this).bind('mousemove', function () { $('div').remove("#current"); }); $(this).bind('mousemove', func); } $("body").bind('mousemove', func) }); As you can see this is pretty much Brute force and it slows down the browser quite a bit. I often experience a lag on the browser as a drag my mouse from one place to another. Is there a way to accomplish this easier and faster and more intuitive. I know you can use the cursor image technique but thats something I'm looking to avoid. Thanks in advance.

  • CSS3 Transitions in PhoneGap: Div Width issues

    - by MeltingDog
    I am building a PhoneGap/Cordova app and have a simple code that uses http://ricostacruz.com/jquery.transit/ to display a div when another div is clicked. <style> #hiddendiv { top: -2000px; position:absolute; } </style> <script> $('#clickme').click( function() { //SHOW DIV $('#hiddendiv').transition({ y: '2100px' }); }); </script> <!--HTML--> <div id="hiddendiv"> Lorem Ipsum blah blah blah Loooong piece of text </div> <div id="clickme"> Click Me </div> And it works fine. The issue is that I cannot scroll on my device once the #hiddendiv is displayed. I this is partly because the page is only about 500px height (not actually set anywhere) whilst the #hiddendiv is about 1500px height Does anyone know of a work around for this?

  • Flash AS3: How to Make scroll bar react to dynamic textfield movement?

    - by HeroicNate
    I've been looking for a tutorial and answer to this for a while but can't find what I'm looking for. I am loading html text into a dynamic textfield, and I have a scrollbar controlling the scroll using the code below. What I want to do is also add scroll up/down buttons and have the scroll bar move in relation to the text scroll. I was just going to use "tracklistingtext.scrollV -- " for the scroll buttons, but right now the scroll bar doesn't recognize the text movement. What do I need to do to get the scroll bar to listen to the text scroll position? var listTextreq:URLRequest=new URLRequest("tracklist.txt"); var listTextLoader:URLLoader = new URLLoader(); var bounds:Rectangle=new Rectangle(scrollMC.x,scrollMC.y,0,300); var scrolling:Boolean=false; function fileLoaded(event:Event):void { tracklistingtext.htmlText=listTextLoader.data; tracklistingtext.multiline=true; tracklistingtext.wordWrap=true; scrollMC.addEventListener(MouseEvent.MOUSE_DOWN, startScroll); stage.addEventListener(MouseEvent.MOUSE_UP, stopScroll); addEventListener (Event.ENTER_FRAME, enterHandler); } listTextLoader.addEventListener(Event.COMPLETE, fileLoaded); listTextLoader.load(listTextreq); function startScroll(e:Event):void { scrolling=true; scrollMC.startDrag(false,bounds); } function stopScroll(e:Event):void { scrolling=false; scrollMC.stopDrag(); } function enterHandler (e:Event):void { if (scrolling == true) { tracklistingtext.scrollV = Math.round(((scrollMC.y - bounds.y)/300)*tracklistingtext.maxScrollV); } } Any help is greatly appreciated.

  • Which way to store this data is effective?

    - by Tattat
    I am writing a game, which need a map, and I want to store the map. The first thing I can think of, is using a 2D-array. But the problem is what data should I store in the 2D-array. The player can tap different place to have different reaction. So, I am thinking store a 2D-array with objects, when player click some position, and I find it in the array, and use the object in that array to execute a cmd. But I have a concern that storing lots of object may use lots of memory. So, I am think storing char/int only. But it seems that not enough for me. I want to store the data like that: { Type:1 Color:Green } No matter what color is, if they are all type 1, the have same reactions in logic, but the visual effect is based on the color. So, it is not easy to store using a prue char/int data, unless I make something like this: 1-5 --> all type 1. 1=color green , 2=color red, 3 = color yellow.... ... 6-10 --> all type 2. 2 = color green, 2 = color red ... ... So, do you have any ideas on how to minimize the ram use, but also easy for me to read... ...thx

  • js loading page message not working on php file

    - by eggman20
    Merry Christmas guys, I found a code that displays a loading message using a gif. It uses the onLoad="init()" in the body tag. It works fine on an HTML file but it doesn't when the file is in PHP. Do I need to change anything in here or this just won't work in a PHP file? here's the code: <body onLoad="init()"> <div id="loading" style="position:absolute; width:100%; text-align:center; top:300px;"> <img src="loading.gif" border=0></div> <script> var ld=(document.all); var ns4=document.layers; var ns6=document.getElementById&&!document.all; var ie4=document.all; if (ns4) ld=document.loading; else if (ns6) ld=document.getElementById("loading").style; else if (ie4) ld=document.all.loading.style; function init() { if(ns4){ld.visibility="hidden";} else if (ns6||ie4) ld.display="none"; } </script> <!-- Content here --> </body> Thanks in advance!!!

  • Why initialize an object to empty

    - by ProgEnthu
    I am learning windows programming with the help of MSDN.Why would somebody initialize an object like the following? WNDCLASS wc = { }; Will this zero all the memory of the object? Whole source code is following: #ifndef UNICODE #define UNICODE #endif #include <windows.h> LRESULT CALLBACK WindowProc(HWND hwnd, UINT uMsg, WPARAM wParam, LPARAM lParam); int WINAPI wWinMain(HINSTANCE hInstance, HINSTANCE, PWSTR pCmdLine, int nCmdShow) { // Register the window class. const wchar_t CLASS_NAME[] = L"Sample Window Class"; WNDCLASS wc = { }; wc.lpfnWndProc = WindowProc; wc.hInstance = hInstance; wc.lpszClassName = CLASS_NAME; RegisterClass(&wc); // Create the window.

  • Attempting to calculate width of Map Overlays on the fly

    - by Bloudermilk
    Hey all- I am working on an Android app that utilizes the Google Maps API MapView, MapController, MapActivity, and ItemizedOverlay. I am basically trying to recreate certain functionalities of the Maps app (damn Google for not providing speech bubbles—for lack of a better name—for items!), particularly those speech bubbles. I have an invisible XML structure for the speech bubble in the XML layout file containing my MapView. The first time I show a speech bubble I grab that XML and remove it from it's current parent, applying some ItemizedOverlay.LayoutParams to it, and add it to the MapView as an Overlay. I position it above the item that was selected, fill it with the proper text, then set it to visible. This all works great. The goal here, though, is to also automatically animate the map to reveal any parts of a speech bubble that may be off-screen when it opens. So I'm trying popup.getWidth() (popup is the instance of my LinearLayout that is the speech bubble) after I do all the manipulation to the bubble, even after I display it to the user. Problem is, popup.getWidth() is returning me the width of the previously displayed popup, not the currently displayed one. I can't figure out why this would be happening if I'm fetching the width after I set it to visible with its new dimensions (which, by the way, are relative when I'm setting them with LayoutParams: fill_content for both width and height).. I have even tried forcing both the MapView and the "popup" to invalidate() before trying to fetch the width. Any ideas why this may be happening? How can I force the View to settle into its new dimensions before trying to fetch them? Thanks! Nick

  • Event consumption in WPF

    - by webaloman
    I have a very simple app written in Silverlight for Windows Phone, where I try to use events. In my App.xaml.cs code behind I have implemented a GeoCoordinateWatcher which registers a gCWatche_PositionChanged method. This works ok, method is called after the position has been changed. What I want to do is fire an other event lets say DBUpdatedEvent after DB has been updated in the gCWatche_PositionChanged method. For this i delclared in the App.xaml.cs public delegate void DBUpdateEventHandler(object sender, EventArgs e); and I have in my App class: public event DBUpdateEventHandler DBUpdated; the event is fired like this in the end of gCWatche_PositionChanged method like this: OnDBUpdateEvent(new EventArgs()); and also I have declared : protected virtual void OnDBUpdateEvent(EventArgs e) { if (DBUpdated != null) { DBUpdated(this, e); } } Now I need to consume this event in my other Windows Phone app page which is a separate class PhoneApplicationPage. So I declared this method in this other Phone Page: public void DBHasBeenUpdated(object sender, EventArgs e) { Debug.WriteLine("DB UPDATE EVENT CATCHED"); } And in the constructor of this page I declared: DBUpdateEventHandler dbEH = new DBUpdateEventHandler(DBHasBeenUpdated); But when I test the application event is fired (OnDBUpdateEvent is called, but DBUpdated is null, therefore DBUpdated is not called - strange) and I have a problem that the other Phone Page is not catching the event at all... Any suggestions? How to catch that event. Thanks.

  • .Net in HTML tp return true if reader object not null, otherwise return false

    - by Phill Healey
    I'm using a DataList to show some data from the database and populating the fields on the html side. I now have a requirement to change the visibility of a panel based on whether or not a db field has data or not. I need to be able to show the panel if the relevant data field has content, and hide it if it doesn't. Eg: <asp:Panel ID="pnlNew" runat="server" Style="margin:0; padding:0; width:42px; height:18px; bottom:5px; right:10px; float:right; position:relative; background:url(../_imgVideoBadge.png) no-repeat;" Visible='<%# Eval("cheese") != null %>' ToolTip="available"></asp:Panel> Obviously this doesn't work in terms of the visible property. But hopefully it gives an idea of what I'm trying to achieve. Any help would be greatly appreciated. I've seen examples previously of doing something along the lines of: a ?? b:c How could this be applied to the above requirement?? Thanks in advance.

  • How to join multiple tables using LINQ-to-SQL?

    - by user603245
    Hi! I'm quite new to linq, so please bear with me. I'm working on a asp.net webpage and I want to add a "search function" (textbox where user inputs name or surname or both or just parts of it and gets back all related information). I have two tables ("Person" and "Application") and I want to display some columns from Person (name and surname) and some from Application (score, position,...). I know how I could do it using sql, but I want to learn more about linq and thus I want to do it using linq. For now I got two main ideas: 1.) var person = dataContext.GetTable<Person>(); var application = dataContext.GetTable<Application>(); var p1 = from p in Person where(p.Name.Contains(tokens[0]) || p.Surname.Contains(tokens[1])) select new {Id = p.Id, Name = p.Name, Surname = p.Surname}; //or maybe without this line //I don't know how to do the following properly var result = from a in Application where a.FK_Application.Equals(index) //just to get the "right" type of application //this is not right, but I don't know how to do it better join p1 on p1.Id == a.FK_Person 2.) The other idea is just to go through "Application" and instead of "join p1 ..." to use var result = from a in Application where a.FK_Application.Equals(index) //just to get the "right" type of application join p from Person on p.Id == a.FK_Person where p.Name.Contains(tokens[0]) || p.Surname.Contains(tokens[1]) I think that first idea is better for queries without the first "where" condition, which I also intended to use. Regardless of what is better (faster), I still don't know how to do it using linq. Also in the end I wanted to display / select just some parts (columns) of the result (joined tables + filtering conditions). I really want to know how to do such things using linq as I'll be dealing also with some similar problems with local data, where I can use only linq. Could somebody please explain me how to do it, I spent days trying to figure it out and searching on the internet for answers. Thank you for your time.

  • How do I avoid killing the native controls on a html5-video when i've started it programmaticly?

    - by Nils
    OK, so the deal is I've started making a little videoplayer, that works by clicking a div with an image, expanding the div and the image, and then exchanges the image with a html5-videotag. the code is as below. (It's very early on, so i know theres a lot that need improving, as in not using javascript to set styles and so on, but nevertheless, any insigts and tips are welcome, besides the answer to the main question) /*Begin Expander*/ var $videoplayer = $('<video width="640" height="360" preload="none" controls="" tabindex="0" style="position: relative;"><source type="video/mp4" src="/restalive/movies/big_buck_bunny.mp4"></source><source type="video/ogg" src="/restalive/movies/big_buck_bunny.ogv"></source></video>').appendTo('body'); $videoplayer.hide(); $(".ExpandVideo").each(function(i){ var $trigger = $(this); var $image = $trigger.find("img"); $image.css({ "width" : "100%" ,"height" : "auto" }) $trigger.css({ "display" : "block" ,"overflow" : "hidden" ,"width" : "200px" ,"float" : "left" }); $trigger.bind("click", function(e){ $trigger.animate({"width" : "640px"}, "fast", function(){ $image.replaceWith($videoplayer); $videoplayer.show(); $videoplayer.attr("id", "video" + i); var video = document.getElementById("video" + i); video.play(); }) }) }); However, the main problem is that when i've fired of the video like this (video.play()), the native controls stop working, i can no longer pause the video, even though the controls are there, and clickable, the video just starts playing immidiatley again when i trie to pause it. Which is a shame, because i want to use the native controls for simplicity.

  • dojo.parser.parse only working first time it's called.

    - by crazymerlin
    I have a page that when a user clicks on a link for some reporting tools, it first asks them to enter some report parameters. I get the parameters dialog as a form using AJAX, based on the id of the link. Each dialog has some dojo controls on it, so I need to parse them when the dialog appears, because it is not originally part of the page. The first dialog when called works fine, but subsequent calls to dialogs fails to parse the dojo controls. Example: showParametersDialog : function(doc) { var content = doc.firstChild.firstChild.data; var container = document.createElement('div'); container.id = 'dialog'; container.innerHTML = content; container.style.background = 'transparent'; container.style.position = 'absolute'; container.style.top = (document.body.clientHeight / 2) - 124 + "px"; container.style.left = (document.body.clientWidth / 2) - 133 + "px"; container.style.display = 'block'; document.body.appendChild(container); // set up date fields var date_from = dojo.byId('date_from'); var date_to = dojo.byId('date_to'); try { date_from.value = dojo.date.locale.format(new Date(), {selector: 'date'}); date_to.value = dojo.date.locale.format(new Date(), {selector: 'date'}); } catch(e) { var now = new Date(); date_from.value = String(now.getMonth() + "/" + now.getDate() + "/" + now.getFullYear()); date_to.value = String(now.getMonth() + "/" + now.getDate() + "/" + now.getFullYear()); } dojo.parser.parse(); } All dialogs have the common date fields. So when I call this dialog the first time, and dojo.parser.parse() is called, it parses the controls on the dialog, but only the first time...after than, no dojo. Any thoughts? Thanks, Paul.

  • Binary serialization and deserialization without creating files (via strings)

    - by the_V
    Hi, I'm trying to create a class that will contain functions for serializing/deserializing objects to/from string. That's what it looks like now: public class BinarySerialization { public static string SerializeObject(object o) { string result = ""; if ((o.GetType().Attributes & TypeAttributes.Serializable) == TypeAttributes.Serializable) { BinaryFormatter f = new BinaryFormatter(); using (MemoryStream str = new MemoryStream()) { f.Serialize(str, o); str.Position = 0; StreamReader reader = new StreamReader(str); result = reader.ReadToEnd(); } } return result; } public static object DeserializeObject(string str) { object result = null; byte[] bytes = System.Text.Encoding.ASCII.GetBytes(str); using (MemoryStream stream = new MemoryStream(bytes)) { BinaryFormatter bf = new BinaryFormatter(); result = bf.Deserialize(stream); } return result; } } SerializeObject method works well, but DeserializeObject does not. I always get an exception with message "End of Stream encountered before parsing was completed". What may be wrong here?

  • GUnload is null or undefined using Directions Service

    - by user1677756
    I'm getting an error using Google Maps API V3 that I don't understand. My initial map displays just fine, but when I try to get directions, I get the following two errors: Error: The value of the property 'GUnload' is null or undefined, not a Function object Error: Unable to get value of the property 'setDirections': object is null or undefined I'm not using GUnload anywhere, so I don't understand why I'm getting that error. As far as the second error is concerned, it's as if something is wrong with the Directions service. Here is my code: var directionsDisplay; var directionsService = new google.maps.DirectionsService(); var map; function initialize(address) { directionsDisplay = new google.maps.DirectionsRenderer(); var geocoder = new google.maps.Geocoder(); var latlng = new google.maps.LatLng(42.733963, -84.565501); var mapOptions = { center: latlng, zoom: 15, mapTypeId: google.maps.MapTypeId.ROADMAP }; map = new google.maps.Map(document.getElementById("map_canvas"), mapOptions); geocoder.geocode({ 'address': address }, function (results, status) { if (status == google.maps.GeocoderStatus.OK) { map.setCenter(results[0].geometry.location); var marker = new google.maps.Marker({ map: map, position: results[0].geometry.location }); } else { alert("Geocode was not successful for the following reason: " + status); } }); directionsDisplay.setMap(map); } function getDirections(start, end) { var request = { origin:start, destination:end, travelMode: google.maps.TravelMode.DRIVING }; directionsService.route(request, function(result, status) { if (status == google.maps.DirectionsStatus.OK) { directionsDisplay.setDirections(result); } else { alert("Directions cannot be displayed for the following reason: " + status); } }); } I'm not very savvy with javascript, so I could have made some sort of error there. I appreciate any help I can get.

  • OpenGL Mipmapping: how does OpenGL decide on map level?

    - by Droozle
    Hi, I am having trouble implementing mipmapping in OpenGL. I am using OpenFrameworks and have modified the ofTexture class to support the creation and rendering of mipmaps. The following code is the original texture creation code from the class (slightly modified for clarity): glEnable(texData.textureTarget); glBindTexture(texData.textureTarget, (GLuint)texData.textureID); glTexSubImage2D(texData.textureTarget, 0, 0, 0, w, h, texData.glType, texData.pixelType, data); glTexParameteri(texData.textureTarget, GL_TEXTURE_MAG_FILTER, GL_LINEAR); glTexParameteri(texData.textureTarget, GL_TEXTURE_MIN_FILTER, GL_LINEAR); glDisable(texData.textureTarget); This is my version with mipmap support: glEnable(texData.textureTarget); glBindTexture(texData.textureTarget, (GLuint)texData.textureID); gluBuild2DMipmaps(texData.textureTarget, texData.glTypeInternal, w, h, texData.glType, texData.pixelType, data); glTexParameteri(texData.textureTarget, GL_TEXTURE_MAG_FILTER, GL_LINEAR_MIPMAP_LINEAR); glTexParameteri(texData.textureTarget, GL_TEXTURE_MIN_FILTER, GL_LINEAR_MIPMAP_LINEAR); glDisable(texData.textureTarget); The code does not generate errors (gluBuild2DMipmaps returns '0') and the textures are rendered without problems. However, I do not see any difference. The scene I render consists of "flat, square tiles" at z=0. It's basically a 2D scene. I zoom in and out by using "glScale()" before drawing the tiles. When I zoom out, the pixels of the tile textures start to "dance", indicating (as far as I can tell) unfiltered texture look-up. See: http://www.youtube.com/watch?v=b_As2Np3m8A at 25s. My question is: since I do not move the camera position, but only use scaling of the whole scene, does this mean OpenGL can not decide on the appropriate mipmap level and uses the full texture size (level 0)?

  • Should I go to school and get my degree in computer science?

    - by ryan
    I'll try and keep this short and simple. I've always enjoyed programming and I've been doing it since high school. Right after I graduated from high school (2002), I opted to skip college because I was offered a software engineer position. I quit after a couple of years later to team up on various startup companies. However, most of them did not launch as well as expected. But it honestly did not matter to me because I've learned so much from that experience. So fast forwarding to today, now turned 25, I need a job due to this tough economic climate. Looking on Craigslist, a lot of the listings require computer science degrees. It's evident now that programming is what I want to do because I seem to never get enough of it. But just the thought of having to push 2 years without attending any real computer class for an Associates at age 25 is very, very discouraging. And the thought of having to learn from basic (Hello WOOOOORRLLLD) just does not seem exciting. I guess I have 3 questions to wrap this up: Should I just suck it up and go back to school while working at McDonalds at age 25? Is there a way where I can just skip all the boring stuff and just get tested with what I know? From your experience, how many jobs use computer science degrees as prerequisites? Or am I screwed and better pray that my next startup will be the next big thing?

  • Javascript style variables with "-" in their name aren't able to be changed?

    Okay, so this bug has cost me quite a bit of time and embarrassment. It seems that any style variable with a - in it's name can't be modified by javascript. As seen here: <!DOCTYPE html> <html lang="en"> <head> <title>Class Test</title> <meta charset="utf-8" /> <style> body { text-align: center; background-color: #ffffff;} #box { position: absolute; left: 610px; top: 80px; height: 50px; width: 50px; background-color: #ff0000; color: #000000;} </style> <script type="text/javascript"> var box = 0; </script> </head> <body> <div id="box" ></div> <script type="text/javascript"> box = document.getElementById('box'); box.style.background-color = "#0000ff"; </script> </body> </html> The box in said example will just remain red. So how do I change a style variable with a - in it's name?

Here is a screenshot: The footer (brown bar) is supposed to be at the bottom... Here is the CSS : /* footer */ #footer{ background:url(../images/bg-footer.png) no-repeat; height:26px; overflow:hidden; padding:35px 0 0 55px; font-size:11px; } #footer p{ margin:0; display:inline; color:#766623; } #footer ul{ margin:0; padding:0; list-style:none; display:inline; } #footer li{ display:inline; background:url(../images/sep-f-nav.gif) no-repeat 100% 55%; padding:0 6px 0 0; position:relative; } * html #footer li{ padding:0 3px 0 3px; } *+html #footer li{ padding:0 3px 0 3px; } #footer a{ color:#30481f; text-decoration:none; } #footer a:hover{ text-decoration:underline; /*Facebook badge Holder*/ .fb-area{ width:287px; padding:0 0; margin:0 0; min-height:100%; }

  • std::ifstream buffer caching

    - by ledokol
    Hello everybody, In my application I'm trying to merge sorted files (keeping them sorted of course), so I have to iterate through each element in both files to write the minimal to the third one. This works pretty much slow on big files, as far as I don't see any other choice (the iteration has to be done) I'm trying to optimize file loading. I can use some amount of RAM, which I can use for buffering. I mean instead of reading 4 bytes from both files every time I can read once something like 100Mb and work with that buffer after that, until there will be no element in buffer, then I'll refill the buffer again. But I guess ifstream is already doing that, will it give me more performance and is there any reason? If fstream does, maybe I can change size of that buffer? added My current code looks like that (pseudocode) // this is done in loop int i1 = input1.read_integer(); int i2 = input2.read_integer(); if (!input1.eof() && !input2.eof()) { if (i1 < i2) { output.write(i1); input2.seek_back(sizeof(int)); } else input1.seek_back(sizeof(int)); output.write(i2); } } else { if (input1.eof()) output.write(i2); else if (input2.eof()) output.write(i1); } What I don't like here is seek_back - I have to seek back to previous position as there is no way to peek 4 bytes too much reading from file if one of the streams is in EOF it still continues to check that stream instead of putting contents of another stream directly to output, but this is not a big issue, because chunk sizes are almost always equal. Can you suggest improvement for that? Thanks.

  • Java Recursion Triangle Standing on Tip

    - by user1629075
    I was wondering how to create triangle out of asterisks on its tip rather than on its base. I have the code for making it stand on its base: public static String printTriangle (int count) { if( count <= 0 ) return ""; String p = printTriangle(count - 1); p = p + "*"; System.out.print(p); System.out.print("\n"); return p; } But then I'm stuck on how to have the greatest number of stars on the top, and then the next least, and so on. I was thinking something along the terms of having (count - p) to have the input of rows be subtracted from the amount of decrease, but then i was confused by this idea because p is string. EDIT: I tried changing the position of printTriangle(count - 1) using my original method without iterations and got 1 star per each line; how can I fix this? public class triangles { public static void main(String[] args) { printTriangle(5); } public static String printTriangle (int count) { if( count <= 0 ) return ""; String p = ""; p = p + "*"; System.out.print(p); System.out.print("\n"); p = printTriangle(count - 1); return p; } }

  • alter prettyphoto to pull from div or span, not title

    - by Jason
    Here's the section of code from prettyphoto.js that I need to alter. What I am trying to achieve is have each photo have a following hidden div or span that holds the description for the photo. This way I can include html in the description. Possible? Thanks! var images = new Array(), titles = new Array(), descriptions = new Array(); if(theGallery){ $('a[rel*='+theGallery+']').each(function(i){ if($(this)[0] === $(_self)[0]) setPosition = i; // Get the position in the set images.push($(this).attr('href')); titles.push($(this).find('img').attr('alt')); descriptions.push($(this).attr('title')); }); }else{ images = $(this).attr('href'); titles = ($(this).find('img').attr('alt')) ? $(this).find('img').attr('alt') : ''; descriptions = ($(this).attr('title')) ? $(this).attr('title') : ''; } $.prettyPhoto.open(images,titles,descriptions); return false; });
