  • codeigniter avoiding html div's

    - by rabidmachine9
    Hello there!Is there a proper syntax to avoid div's in codeigniter? I don't really like opening and closing tags all the time... <div class="theForm"> <?php echo form_open('edit/links');//this form uploads echo "Enter the Name: ". form_input('name','name'); echo "Enter the Link: ". form_input('url','url'); echo " ".form_submit('submit', 'Submit'); echo form_close(); if (isset($linksQuery) && count($linksQuery)){ foreach($linksQuery as $link){ echo anchor($link['link'], $link['name'].".", array("class" => "links")); echo form_open('edit/links',array('class' => 'deleteForm')); echo form_hidden('name',$link['name']); echo " ".form_submit('delete','Delete'); echo form_close(); echo br(2); } } ?> </div>

  • Can anyone help with this (Javascript arrays)?

    - by Rich
    Hi I am new to Netui and Javascript so go easy on me please. I have a form that is populated with container.item data retuned from a database. I am adding a checkbox beside each repeater item returned and I want to add the container item data to an array when one of the checkboxes is checked for future processing. The old code used Anchor tag to capture the data but that does not work for me. <!--netui:parameter name="lineupNo" value="{container.item.lineupIdent.lineupNo}" /> here is my checkbox that is a repeater. <netui:checkBox dataSource="{pageFlow.checkIsSelected}" onClick="checkBoxClicked()" tagId="pceChecked"/> this is my Javascript function so far but I want to a way to store the container.item.lineupIdent.lineupNo in the array. function checkBoxClicked() { var checkedPce = []; var elem = document.getElementById("PceList").elements; for (var i = 0; i < elem.length; i ++) { if (elem[i].name == netui_names.pceChecked) { if (elem[i].checked == true) { //do some code. } } } } I hope this is enough info for someone to help me. I have searched the web but could not find any examples. Thanks.

  • PasswordFiled char[] to String in Java connection MySql?

    - by user1819551
    This is a jFrame to connect to the database and this is in the button connect. My issue is in the passwordField NetBeans make me do a char[], but my .getConnection not let me insert the char[] ERROR: "no suitable method found for getConnection(String,String,char[])". So I will change to String right? So when I change and run the jFrame said access denied. when I start doing the System.out.println(l) " Give me the right answer" Like this: "Alex". But when I do the System.out.println(password) "Give me the Array spaces and not the value" Like this: jdbc:mysql://localhost/home inventory root [C@5be5ab68 <--- Array space . What I doing wrong? try { Class.forName("org.gjt.mm.mysql.Driver"); //Load the driver String host = "jdbc:mysql://"+tServerHost.getText()+"/"+tSchema.getText(); String uName = tUsername.getText(); char[] l = pPassword.getPassword(); System.out.println(l); String password= l.toString(); System.out.println(host+uName+l); con = DriverManager.getConnection(host, uName, password); System.out.println(host+uName+password); } catch (SQLException | ClassNotFoundException ex) { JOptionPane.showMessageDialog(this, ex.getMessage()); } }

  • Custom punctuation function making script run over the php's 60s runtime limit

    - by webmasters
    I am importing allot of product data from an XML file (about 5000 products). When I run the script I can make it work in about 10-12 seconds. Now, when I add this punctuation function which makes sure each product description ends with a punctuation sign, the code runs until the php 60 seconds loadtime on my server but I'm not getting any errors. I have error reporting turned on. I just get a final error that the script could not load in 60 seconds. The question is, looking at this function, is it that resource consuming? What can I do to make it faster? function punctuation($string){ if(strlen($string) > 5){ // Get $last_char $desired_punctuation = array(".",",","?","!"); $last_char = substr($string, -1); // Check if $last_char is in the $desired_punctuation array if(!in_array($last_char, $desired_punctuation)){ // strip the $mytrim string and get only letters at the end; while(!preg_match("/^[a-zA-Z]$/", $last_char)){ $string = substr($string, 0, -1); $last_char = substr($string, -1); } // add "." to the string $string .= '.'; } } return $string; } If the function is ok, the long runtime must come from something else which I'll have to discover. I just want your input on this part.

  • Is there any well-known paradigm for iterating enum values?

    - by SadSido
    I have some C++ code, in which the following enum is declared: enum Some { Some_Alpha = 0, Some_Beta, Some_Gamma, Some_Total }; int array[Some_Total]; The values of Alpha, Beta and Gamma are sequential, and I gladly use the following cycle to iterate through them: for ( int someNo = (int)Some_Alpha; someNo < (int)Some_Total; ++someNo ) {} This cycle is ok, until I decide to change the order of the declarations in the enum, say, making Beta the first value and Alpha - the second one. That invalidates the cycle header, because now I have to iterate from Beta to Total. So, what are the best practices of iterating through enum? I want to iterate through all the values without changing the cycle headers every time. I can think of one solution: enum Some { Some_Start = -1, Some_Alpha, ... Some_Total }; int array[Some_Total]; and iterate from (Start + 1) to Total, but it seems ugly and I have never seen someone doing it in the code. Is there any well-known paradigm for iterating through the enum, or I just have to fix the order of the enum values? (let's pretend, I really have some awesome reasons for changing the order of the enum values)...

  • matching images inside a link in regex

    - by user225269
    What is wrong with regex pattern that I created: $link_image_pattern = '/\<a\shref="([^"]*)"\>\<img\s.+\><\/a\>/'; preg_match_all($link_image_pattern, $str, $link_images); What I'm trying to do is to match all the links which has images inside of them. But when I try to output $link_images it contains everything inside the first index: <pre> <?php print_r($link_images); ?> </pre> The markup looks something like this: Array ( [0] = Array ([0] = " <p>&nbsp;</p> <p><strong><a href="url">Title</a></strong></p> <p>Desc</p> <p><a href="{$image_url2}"><img style="background-image:none;padding-left:0;padding-right:0;display:inline;padding-top:0;border-width:0;" title="image" border="0" alt="image" src="{$image_url2}" width="569" height="409"></a></p> But when outputting the contents of the matches, it simply returns the first string that matches the pattern plus all the other markup in the page like this: <a href="{$image_url}"><img style="background-image:none;padding-left:0;padding-right:0;display:inline;padding-top:0;border-width:0;" title="image" border="0" alt="image" src="{$image_url}" width="568" height="347"></a></p> <p>&nbsp;</p> <p><strong><a href="url">Title</a></strong></p> <p>Desc</p> <p><a href="{$image_url2}"><img style="background-image:none;padding-left:0;padding-right:0;display:inline;padding-top:0;border-width:0;" title="image" border="0" alt="image" src="{$image_url2}" width="569" height="409"></a></p>")

  • Removing random object from parent CCprite

    - by Natty
    probably this is a simple problem to solve, since I'm quite new. I have a scene with a waiter holding a tray of food (the food is a random CCSprite choosen from an array) each time he comes onscreen he holds a new piece of food (the user touches the food and the waiter walks off to return again with a new piece of food however I cant seem to delete the old peice of food from the screen as it says the child is already added... any help would be great -(id) init { ///other code then... waiterOnSCreen = [CCSprite spriteWithSpriteFrameName:@"CatUP.png"]; waiterOnSCreen.position = ccp(CatOffSCreenPosX, catXpos); [self addChild:waiterOnSCreen z:0]; //moving the waiter // the random food sprite is added later to the waiter // [waiterOnSCreen addChild:myRandomSprite]; } -(void)LoadRandomFood { ///I make my array here then... int i = arc4random() % [RandomFood count]; myRandomSprite = (CCSprite *)[RandomFood objectAtIndex:i]; //waiterOnSCreen is a CCSprite added on the init [waiterOnSCreen addChild:myRandomSprite]; myRandomSprite.position=ccp(290,220); myRandomSprite.tag = RandomFoodTag; } } later in if(CGRectContainsPoint(waiterOnSCreen.boundingBox, location)) { //trying to remove the food here //Ive already tried to remove the sprite using [self removeChildByTag:RandomeObjectTag]; //and also CCSprite *wantedSprite = (CCSprite *)[self getChildByTag:RandomFoodTag]; [wantedSprite removeFromParentAndCleanup:YES]; } }

  • Variable wont echo

    - by jonnnnnnnnnie
    I have the following code, where the var $username doesn't echo, when you type in a value. //TODO: SET AUTH TOKEN as random hash, save in session $auth_token = rand(); if (isset($_POST['action']) && $_POST['action'] == 'Login') { $errors = array(); //USED TO BUILD UP ARRAY OF ERRORS WHICH ARE THEN ECHOED $username = $_POST['username']; if ($username = '') { $errors['username'] = 'Username is required'; } echo $username; // var_dump($username) returns string 0 } require_once 'login_form.html.php'; ?> login_form is this: <form method="POST" action=""> <input type="hidden" name="auth_token" value="<?php echo $auth_token ?>"> Username: <input type="text" name="username"> Password: <input type="password" name="password1"> <input type="submit" name="action" value="Login"> </form> The auth token part isn't important, it just when I type in a value in username textbox and press the login button, the username wont echo, var_dump returns string (0) and print_r is just blank.

  • When to pass pointers in functions?

    - by yCalleecharan
    scenario 1 Say my function declaration looks like this: void f(long double k[], long double y[], long double A, long double B) { k[0] = A * B; k[1] = A * y[1]; return; } where k and y are arrays, and A and B are numerical values that don't change. My calling function is f(k1, ya, A, B); Now, the function f is only modifying the array "k" or actually elements in the array k1 in the calling function. We see that A and B are numerical values that don't change values when f is called. scenario 2 If I use pointers on A and B, I have, the function declaration as void f(long double k[], long double y[], long double *A, long double *B) { k[0] = *A * *B; k[1] = *A * y[1]; return; } and the calling function is modified as f(k1, ya, &A, &B); I have two questions: Both scenarios 1 and 2 will work. In my opinion, scenario 1 is good when values A and B are not being modified by the function f while scenario 2 (passing A and B as pointers) is applicable when the function f is actually changing values of A and B due to some other operation like *A = *B + 2 in the function declaration. Am I thinking right? Both scenarios are can used equally only when A and B are not being changed in f. Am I right? Thanks a lot...

  • Reverse wildcard search in codeigniter

    - by Andy Platt
    I am implementing a snippet-based content management system into my current project. Snippets can be associated with a page either by exact match of the full url falling back to a wildcard match on a partial url or finally a default snippet. To implement this I have a created table of page associations with a wildcard flag, the system first checks the current url against the non-wildcard associations and if it doesn't find a match it checks against the partial url's where the wildcard flag is set. In order to achieve this I am getting all the partial url's from the database and putting them into an array then walking the array to check for a match against the current url: protected function _check_wildcard($url = NULL) { if($url) { $q = $this->db->where('wildcard' ,'Y') ->from('content') ->get(); $wildcards = $q->result_array(); foreach($wildcards AS $wildcard) { if(strpos($url,$wildcard['url']) > 0) { return $wildcard['snipppet_id']; } } } else { return NULL; } } Can anyone suggest a better way to do this - preferably one that doesn't involve having to constantly download the full list of all the wildcards each time I load a page as I am afraid that this will have a negative effect on the scalability of the system down the line?

  • HTML + Button with text and image on it.

    - by lucky
    Hello, I have a problem in creating a Button with text and image on it. <td> <button type="submit" name="report" value="Report" <?php if($tab == 'Excel') echo "id=\"tab_inactive\""; else echo "id=\"tab_active\"" ; ?>> <img src="images/report.gif" alt="Report"/>Report </button> <button type="submit" name="excel" value="Excel" <?php if($tab == 'Excel' ) echo "id=\"tab_active\""; else echo "id=\"tab_inactive\"" ; ?>> <img src="images/Excel.gif" alt="Excel" width="16" height="16" /> Excel </button> </td> Here $tab is $tab = strlen(trim($_POST[excel]))>0 ? $_POST[excel] : $_POST[report]; I tried this way, but this is behaving so strangely. On click the button:- The submit function is working properly in firefox, but not in IE. Instead of submitting the value(in this example values are 'Report' and 'Excel'), indeed it is submitting the label of the button. That is if i am checking the value of array PRINT_R($_POST). The value of it is Array ( [report] =>(Icon that i used) Report [excel] => (Icon that i used) Excel [frm_analysis] => [to_analysis] => ) Here i have more than 1 button, then all the labels are submitted eventhough one of them is pressed. i dont how to capture which button is pressed. I even tried changing button type=button and onclick="document.formname.submit()" Even this is resulting in the same. Can you please help me to solve this.

  • Is there an Easier way to Get a 3 deep Panel Control from a Form in order to add a new Control to it programmatically?

    - by Mark Sweetman
    I have a VB Windows Program Created by someone else, it was programmed so that anyone could Add to the functionality of the program through the use of Class Libraries, the Program calls them (ie... the Class Libraries, DLL files) Plugins, The Plugin I am creating is a C# Class Library. ie.. .dll This specific Plugin Im working on Adds a Simple DateTime Clock Function in the form of a Label and inserts it into a Panel that is 3 Deep. The Code I have I have tested and it works. My Question is this: Is there a better way to do it? for instance I use Controls.Find 3 different times, each time I know what Panel I am looking for and there will only be a single Panel added to the Control[] array. So again Im doing a foreach on an array that only holds a single element 3 different times. Now like I said the code works and does as I expected it to. It just seems overly redudant, and Im wondering if there could be a performance issue. here is the code: foreach (Control p0 in mDesigner.Controls) if (p0.Name == "Panel1") { Control panel1 = (Control)p0; Control[] controls = panel1.Controls.Find("Panel2", true); foreach (Control p1 in controls) if (p1.Name == "Panel2") { Control panel2 = (Control)p1; Control[] controls1 = panel2.Controls.Find("Panel3", true); foreach(Control p2 in controls1) if (p2.Name == "Panel3") { Control panel3 = (Control)p2; panel3.Controls.Add(clock); } } }

  • Win conditions for a connect-4 like game

  • How do I get a reference to a rootViewController to a sub-view?

    - by Andy
    An answer posted for one of my previous questions brings up another question; I am calling a new view controller, "RuleBuilder," from my rootViewController. The rootViewController holds a reference to a contacts array. How do I get a reference to that array into the RuleBuilder? I tried adding UITableViewController *rootViewController; ... @property (nonatomic, retain) UITableViewController *rootViewController; to RuleBuilder.h, and then @synthesize rootViewController; in RuleBuilder.m. When I instantiate and push the RuleBuilder from within rootViewController, I do this: ruleBuilder.rootViewController = self; But when I try this [rootViewController.contacts addObject:newContact]; from within RuleBuilder, I get a compiler error to the effect of "request for 'contacts' in something not a struct" (or very similar; I haven't implemented this exact snippet of code, but I tried an identical approach not an hour ago for a couple of different references that I never was able to get working). Thanks, again, for your help.

  • C Map String to Function

    - by Scriptonaut
    So, I'm making a Unix minishell, and have come to a roadblock. I need to be able to execute built-in functions, so I made a function: int exec_if_built_in(char **args) It takes an array of strings(the first being the command, and the rest being arguments). For non built-in commands I simply use something like execvp, however I need to find a way to map the first string to a function. I was thinking of making two arrays, one of strings, and another with their corresponding function pointers. However, since many of these functions will be different(return and accept different things), this approach won't work. I also thought of making an array of structs with a name property and a function pointer property, however once again due to the varied nature of the functions I'll be using, this won't work. So, what's the best way to execute a function based on the input of a string? How do I map a string to a certain function? I'm not very familiar with function pointers so I may be missing something. Thank you guys for the help :)

  • Java: GatheringByteChannel advantages?

    - by Jason S
    I'm wondering when the GatheringByteChannel's write methods (taking in an array of ByteBuffers) have advantages over the "regular" WritableByteChannel write methods. I tried a test where I could use the regular vs. the gathering write method on a FileChannel, with approx 400KB/sec total in ByteBuffers of between 23-27 bytes in length in both cases. Gathering writes used an array of 64. The regular method used up approx 12% of my CPU, and the gathering method used up approx 16% of my CPU (worse than the regular method!) This tells me it's NOT useful to use gathering writes on a FileChannel around this range of operating parameters. Why would this be the case, and when would you ever use GatheringByteChannel? (on network I/O?) Relevant differences here: public void log(Queue<Packet> packets) throws IOException { if (this.gather) { int Nbuf = 64; ByteBuffer[] bbufs = new ByteBuffer[Nbuf]; int i = 0; Packet p; while ((p = packets.poll()) != null) { bbufs[i++] = p.getBuffer(); if (i == Nbuf) { this.fc.write(bbufs); i = 0; } } if (i > 0) { this.fc.write(bbufs, 0, i); } } else { Packet p; while ((p = packets.poll()) != null) { this.fc.write(p.getBuffer()); } } }

  • HTML5 card game [closed]

    - by ChrisCa
    I created a card game in silverlight a year or so ago in order to learn a bit about Silverlight. I am now wanting to make a HTML5 version of the game in an effort to learn a little bit more about that. I am thinking I'd like to take advantage of stuff like Knockout.js and WebSockets and the canvas element. Now what I'm confused about is how to lay out the cards on the screen. With Silverlight I was able to make a "Hand" control, which was made up of two sub controls - the cards the player has in their hand and the ones they have on the table. And they in turn were made up of Card controls. Now I don't believe there is the concept on a User Control in javascript. So I am possibly thinking about this in entirely the wrong way. So my question is - how could I lay out some cards on the table and perhaps make reuse of something for each player? I have a client side JSON object called game, which contains an array of players. Each player has a hand which is made up of an array of in-hand cards and on-table cards. Ideally I would like to bind these to something using Knockout.js - but I don't know what I could bind to. Would I simply position images (of cards) on a canvas? Is there a way to make some kind of Hand object that each player could have and that I could bind to? Any advice? Or sample code you've seen elsewhere?

  • How to iterate & retrieve values from NSArray of NSArrays of NSDictionaries

    - by chinjazz
    I'm stumpped on how iterate and get values for an Array of Arrays of NSDictionaries (different classes/entities). Here's what I'm currently doing: 1) Constructing two separate arrays of NSDictionaries (different entities) 2) Combining both arrays with: NSMutableArray *combinedArrayofDicts = [[NSMutableArray alloc] initWithObjects: sizesArrayOfDicts, wishListArrayOfDicts , nil]; 3) Then archive combinedArrayofDicts : NSData *dataToSend = [NSKeyedArchiver archivedDataWithRootObject:combinedArrayofDicts]; 4) Transmit over GameKit [self.session sendDataToAllPiers:dataToSend withDataMode: GKSendDataReliable error:nil]; 5) How would I manage traversing thru this array on the receiving end? I want to fetch values by for each class which is key'ed by classname: Here's how it looks via NSLog (2 Sizes Dicts, and 1 Wishlist Dict) Printing description of receivedArray: <__NSArrayM 0xbc65eb0>( <__NSArrayM 0xbc651f0>( { classname = Sizes; displayOrder = 0; share = 1; sizeType = Neck; value = "13\" or 33 (cm)"; }, { classname = Sizes; displayOrder = 0; share = 1; sizeType = Sleeve; value = "34\" or 86 (cm)"; } ) , <__NSArrayM 0xbc65e80>( { classname = Wishlist; detail = ""; displayOrder = 0; imageString = ""; latitude = "30.33216666666667"; link = "http://maps.google.com/maps?q=loc:30.332,-81.41"; longitude = "-81.40949999999999"; name = bass; share = 1; store = ""; } ) ) (lldb) In my for loop I'm issuing this: NSString *value = [dict objectForKey:@"classname"]; and get an exception: * Terminating app due to uncaught exception 'NSInvalidArgumentException', reason: '-[__NSArrayM objectForKey:]: unrecognized selector sent to instance 0xbc651f0' Is this frowned upon as far as mixing object types in arrays of arrays?

  • How do I remove 3 characters from the end of an NSURL?

    - by saywhatman
    Hey, my first question! I've been able to code up most of this RSS reader without enlisting help (through a lot of searches through stackoverflow!) but I'm stumped here. NSString *urlbase = [[NSString alloc] initWithFormat:[links3 objectAtIndex:indexPath.row]]; [[UIApplication sharedApplication] openURL:[NSURL URLWithString:urlbase]]; NSCharacterSet *whitespaces = [NSCharacterSet whitespaceCharacterSet]; NSPredicate *noEmptyStrings = [NSPredicate predicateWithFormat:@"SELF != ''"]; NSArray *parts = [urlbase componentsSeparatedByCharactersInSet:whitespaces]; NSArray *filteredArray = [parts filteredArrayUsingPredicate:noEmptyStrings]; urlbase = [filteredArray componentsJoinedByString:@" "]; NSLog(@"%@ %i" , urlbase, 4353); [[UIApplication sharedApplication] openURL:[NSURL URLWithString:urlbase]]; The links3 array is a NSMutableArray with strings. The first few lines work flawlessly in eliminating the space at the beginning each string from that array, which is stored in 'urlbase' so they look fine when they come out. When we NSLog urlbase, we see: http://www.feedzilla.com/r/D7E6204FEDBFE541314B997AAB5D2DF9CBA2EFEE But, when we use: [[UIApplication sharedApplication] openURL:[NSURL URLWithString:urlbase]] We see: http://www.feedzilla.com/r/D7E6204FEDBFE541314B997AAB5D2DF9CBA2EFEE%0A How can I fix this? Can I remove those tail elements somehow? Thanks!

  • Is there command-line tool to extract typedef, structure, enumeration, variable, function from a C or C++ file?

    - by FooF
    I am desiring a command-line tool to extract a definition or declaration (typedef, structure, enumeration, variable, or function) from a C or C++ source file. Also a way to replace an existing definition/declaration would be handy (after transforming the extracted definition by a user-submitted script). Is there such generic tool available, or is some resonably close approximation of such a tool? Scriptability and ability to hook-up with user created scripts or programs is of importance here, although I am academically curious of GUI programs too. Open source solutions for Unix/Linux camp are preferred (although I am curious of Windows and OS X tools too). Primary language interests are C and C++ but more generic solution would be even better (I think we do not need super accurate parsing capabilities for finding, extracting and replacing a definition in a program source file). Sample Use Cases (extra - for the curious mind): Given deeply nested structs and variable (array) initializations of these types, suppose there is a need to change a struct definition by adding or reordering fields or rewriting the variable/array definitions in more readable format without introducing errors resulting from manual labor. This would work by extracting the old initializations, then using a script/program to write the new initializations to replace the old ones. For implementing a code browsing tool - extract a definition. Decorative code generation (e.g. logging function entries / returns). Scripted code structuring (e.g. extract this and that thing and put in different place without change - version control commit comment could document the command to perform this operation to make it evident and verifiable that nothing changed). Note about tags: More accurate tag than code-generation would be code-transformation but it does not exist.

This mapping operation seems like a good beginning. function(doc) { var type = doc.type; var groups = doc.groups; if(type == "user" && groups.length > 0) { for(var i = 0; i < groups.length; i++) { emit(groups[i], doc); } } } But there's obviously something very wrong with my attempt at a reduce: function(key, values, rereduce) { var set = []; var seen = []; for(var i = 0; i < values.length; i++) { var _id = values[i]._id; if(seen.indexOf(_id) == -1) { seen.push(_id); set.push(values[i]); } } return set; } I'm running CouchDB 0.10dev. Any help appreciated.

  • JQUERY - how to get updated value after ajax removes data from within it?

    - by Brian
    I have a an element with thumbnails. I allow users to sort their display order (which fires off an update to the DB via ajax). I also allow them to delete images (which, after deletion, fires off a request to update the display order for all remaining images). My problem is with binding or live I think, but I don't know where to apply it. The array fired off upon delete contains ALL the ids for the images that were there on page load. The issue is that after they delete an image the array STILL contains the original ids (including the one that was deleted) so it is obviously not refreshing the value of the element after ajax has removed things from inside it. I need to tell it to go get the refreshed contents... From what I have been reading, this is normal but I don't understand how to tie it into my routine. I need to trigger the mass re-ordering after any deletion. Any ideas gurus? $('a.delimg').click(function(){ var parent = $(this).parent().parent(); var id = $(this).attr('id'); $.ajax({ type: "POST", url: "../updateImages.php", data: "action=delete&id=" + id, beforeSend: function() { parent.animate({'backgroundColor':'#fb6c6c'},300); $.jnotify("<strong>Deleting This Image & Updating The Image Order</strong>", 5000); }, success: function(data) { parent.slideUp(300,function() { parent.remove(); $("#images ul").sortable(function() { //NEEDS TO GET THE UPDATED CONTENT var order = $(this).sortable("serialize") + '&action=updateRecordsListings'; $.post("../updateImages.php", order, function(theResponse){ $.jnotify("<strong>" + theResponse + "</strong>", 2000); }); }); }); } }); return false; }); Thanks for any help you can be.

  • Fade in and out a div contains video embedHTML in jquery

    - by Ahmy
    I have a div and three links when a link is clicked the div is set its innerHTML with an embedHTML of video and i need to cause some effects when the current div video is changed on clicking the link Example : <a id="Link1" onClick="ChangeVideo(1)">Link1</a> <a id="Link2" onClick="ChangeVideo(2)">Link2</a> <a id="Link3" onClick="ChangeVideo(3)">Link3</a> <div id="CurrVideo"></div> <script type="text/javascript" language="javascript"> //The ArrEmbed is an array that is set on the load of the page:: var ArrEmbed = new Array(); function ChangeVideo(index) { $('#CurrVideo).fadeTo(1000,0.25,function(){ document.getElementById("CurrVideo").innerHTML = ArrEmbed[index-1]; }); $('#CurrVideo).fadeTo(500,1.25); } </script> The effect is not noticeable and fading with opacity diminshing is not noticed even if the duration time is increased (e.g. 'slow') and when i replace the EmbedHTML with image this code is applicable and the effect of fading is noticed but with the video it is not noticeable so how can i solve this problem ? Thanks in advance for any try Note: The embedHTML differ as it may come from youtube or any server or from my JWPlayer.
