  • Notice Undefined index url

    - by user1906992
    I'm doing youtube mvc tutorial http://www.youtube.com/watch?v=Aw28-krO7ZM and have stopped on the best first step: my index.php file: <?php $url = $_GET['url']; require 'controllers/' . $url . '.php'; My .htaccess file: RewriteEngine On RewriteCond %{REQUEST_FILENAME} !-d RewriteCond %{REQUEST_FILENAME} !-f RewriteCond %{REQUEST_FILENAME} !-l RewriteRule ^(.+)$ index.php?url=$1 [QSA,L] so, the question is next: when i go on any other url except 'index' it works good. So what's wrong with 'index' url? Notice: Undefined index: url in /var/www/sadman/index.php on line 2 Warning: require(controllers/.php) [function.require]: failed to open stream: No such file or directory in /var/www/sadman/index.php on line 4 Btw, i have LAMP, and i think my settings are wright.

  • Is there a way to use jquery without using the $ - accessor?

    - by ManBugra
    I'am dealing here with a web application that defines somewhere in a java script file: $ = function() { return document.getElementById(arguments[0]); } Every other script, jsp page and dynamic content loaded from db depends on the semantic of the $ - sign working as 'document.getElementById'. Now i would like to start using jqery. So i think i have 2 options: refactor the existing application (all script files, jsp's, dynamic content etc.) somehow introduct jquery as something differnt than '$' (not really an option) don't start using jquery Are there any other solutions? What would you do?

  • Is it possible for a parent to use a child's constant or static variables from inside a static metho

    - by ryeguy
    Below is an example of what I'm trying to do. The parent can't access any of the child's variables. It doesn't matter what technique I use (static or constants), I just need some kind of functionality like this. class ParentClass { public static function staticFunc() { //both of these will throw a (static|const) not defined error echo self::$myStatic; echo self::MY_CONSTANT; } } class ChildClass extends ParentClass { const MY_CONSTANT = 1; public static $myStatic = 2; } ChildClass::staticFunc();

  • How do i resolve method Overlapping in java/Processing [duplicate]

    - by user3718913
    This question already has an answer here: How do I compare strings in Java? 24 answers I have two methods/function in a class, called, Qestion1 and Question2, i want it in such a way that after the user has answered Question one correctly, the Question 2 method is called. Whenever i call the method 2, it displays both of them together instead exiting the first method first. Here's a dummy code to illustrate what i'm saying: void Question1() { String question="What is the capital of England?"; String Answer="London"; if(Answer=='London') { Question2(); } } void Question2() { String question="What is the capital of California?"; String Answer="Sacramento"; if(Answer=='Sacramento') { Question3(); } } Pls, this question is in no way related to that other question. Pls peruse the thread again.

  • jQuery can't get if statement to work

    - by jstacks
    I'm looking help with an If Statement. I'm trying to finalize this horizontal scrolling I have and the last bit is to not just disable scrolling when the end is reached, but to also disable (well, change color) the scroll buttons at that point as well. And change back when they are scrollable again. http://jsfiddle.net/stfzy/83/ EDIT* I've updated the JQuery and have everything working except just one if statement: $('div#arrowL').click(function(){ if(index < 0 ){ //can't scroll $('div#arrowL').addClass('active'); } }); I need to add this class back when you can't scroll left anymore. And I think the issue is with the "index < 0" portion but I don't see what I need to change it to to get it to work. Any help is appreciated.

  • How do I "step over" jQuery code while debugging?

    - by Scott Rippey
    While stepping through a script that uses jQuery, I just want to test the code I wrote. I don't want to step into the jQuery file -- I'm not debugging jQuery, just my own file. Are there any ways to tell a debugger to not step into the jQuery file? I use Visual Studio + Internet Explorer, as well as Firefox + Firebug for stepping through code ... and both seem to love to step through dozens of jQuery statements. For example, say I have a script like this: $("div").each(function() { $(this).hide(); }); I would like to press "step into" and not see the implementation of ".each()" etc... In C#, this is possible by using the [DebuggerStepThrough()] attribute on a class. But that doesn't help with JavaScript.

  • How to access constant defined in child class from parent class functions?

    - by kavoir.com
    I saw this example from php.net: <?php class MyClass { const MY_CONST = "yonder"; public function __construct() { $c = get_class( $this ); echo $c::MY_CONST; } } class ChildClass extends MyClass { const MY_CONST = "bar"; } $x = new ChildClass(); // prints 'bar' $y = new MyClass(); // prints 'yonder' ?> But $c::MY_CONST is only recognized in version 5.3.0 or later. The class I'm writing may be distributed a lot. Basically, I have defined a constant in ChildClass and one of the functions in MyClass (father class) needs to use the constant. Any idea?

  • Pulling .live() functionality out of jQuery

    - by Daniel
    I am writing a Firefox Add-On that currently is depending on jQuery for the following things: Selectors Animations A special .live("focus") hail-mary event-catching maneuver that happens to work with jQuery 1.4.2 (but not 1.4.4) jQuery isn't well suited for functioning inside XUL, and it's a miracle we've gotten this far with it. We're trying to remove the jQuery requirements, the first two are easy (animations are simple, and we can use .querySelector() instead of jQuery), but the .live has proven impossible to do on our own. I've tried reading the source code, but I haven't been able to piece it apart. What is the jQuery .live function doing? There's clearly a lot more going on than document.addEventListener("focus"/"focusin",function_to_pick_apart_events). What else is going on here?

  • Background position image overlay (Works in IE, not in Mozilla/Chrome/Safari)

    - by amm229
    Hi all, I am having an issue positioning a background image using the following jquery background position command in Firefox, Google Chrome, and Safari. The code works correctly in IE 8. $('#element).css({ backgroundPosition: 'xpx ypx' }); The x position of the image is calculated dynamically based on window size and the y position is static. The css appears to be modified correctly, however, the background image I am attempting to overlay is absent. See jscript code below: $(window).resize(function () { // image positioning variables var windowwidth = $(window).width(); var imgwidth = $('#imgFluid').width(); var offset = $('#divFluidBlur').offset(); // calculate and implement position blurPositionLeft = (windowwidth - imgwidth) - offset.left; $('#divFluidBlur').css({ backgroundPosition: blurPositionLeft + 'px' + ' 30px' }); // debug: display actual css Background Position of element to text box $("#txtActualBackgroundpos").val(document.getElementById ("divFluidBlur").style.backgroundPosition); Thanks in advance for your help, Andrew

  • No class def find error

    - by John Smith
    I have the following piece of code which helps me to read the paths of all the files in a directory and its subdirectories : File dir = new File("directory path"); try { System.out.println("Getting all files in " + dir.getCanonicalPath() + " including those in subdirectories"); } catch (IOException e1) { // TODO Auto-generated catch block e1.printStackTrace(); } List<File> files = (List<File>) FileUtils.listFiles(dir, TrueFileFilter.INSTANCE, TrueFileFilter.INSTANCE); for (File file : files) { try { System.out.println("file: " + file.getCanonicalPath()); } catch (IOException e1) { // TODO Auto-generated catch block e1.printStackTrace(); } } The problem is that I get a java.lang.NoClassDefFoundError: org/apache/commons/io/filefilter/TrueFileFilter error. I've imported the necessary libraries. I mention that I work on a plugin project. This code runs in a class with main function. I don't understand why it gave me this error. Thank you !

  • JavaScript prototype(ing) question

    - by OneNerd
    Trying to grasp Prototyping in Javascript. Trying to create my own namespace to extend the String object in JavaScript. Here is what I have so far (a snippet): var ns { alert: function() { alert (this); } } String.prototype.$ns = ns; As you can see, I am trying to place what will be a series of functions into the ns namespace. So I can execute a command like this: "hello world".$ns.alert(); But the problem is, the this doesn't seem to reference the text being sent (in this case, "hello world"). What I get is an alert box with the following: [object Object] Not having a full grasp of the object-oriented nature of JavaScript, I am at a loss, but I am guessing I am missing something simple. Does anyone know how to achieve this? Thanks -

  • Analog of Java Form Layout in Qt

    - by Narek
    Once I have programmed GUI with Java and have used Form Layouts. Form layout (if I am not mistaken that is from SWT library) made possible to give right, left, top and bottom adges of any GUI element (widget) with respect to other widgets in the same widget (parent widget) or with respect to the adges of parent widget. So it was possible to control the future of widgets that are inside of another one, when that "another widget" is being resized. In Qt I have find the QFormLayout which is similar to Java one, but seems I can't handle with widgets as flexible in terms of relative positioning, as it was with Java's Form Layout. So are there any other means to give a widget position with respect to the others (without overloading resizeEvent function) as that was in Java? Thanks.

  • Parsing through Arabic / RTL text from left to right

    - by Dan W
    Let's say I have a string in an RTL language such as Arabic with some English chucked in: string s = "Test:?????;?????;?????;a;b" Notice there are semicolons in the string. When I use the Split command like string[] spl = s.Split(';');, then some of the strings are saved in reverse order. This is what happens: ??Test:????? ????? ????? a b The above is out of order compared to the original. Instead, I expect to get this: ?Test: ????? ????? ????? a b I'm prepared to write my own split function. However, the chars in the string also parse in reverse order, so I'm back to square one. I just want to go through each character as it's shown on the screen.

  • Java Wicket - Calling javascript ( JQuery ) before AJAX

    - by user1428051
    I got this thing i'm trying to solve: I got a ListView created using Wicket ( 1.5 ) with a lot of elements and a scroll. When new items are available, the user is asked if he would like to refresh the list via a message backed by an AjaxLink: public void onClick(AjaxRequestTarget ajaxTarget) { /* do something ... */ ajaxTarget.addComponent(_list); } So on click the list gets reloaded and the scroll position is reset to zero. Is there any way i can call JavaScript before the list reloads the save the scroll position? (I know how to get/save the scroll position ( .scrollTop() ) , i just don't know how to call a function right before AJAX ).

  • nextSibling issue, should be simple

    - by SoLoGHoST
    Ok, I'm trying to come to grips with this nextSibling function in JS. Here's my issue within the following code... var fromRow = document.getElementById("row_1"); while(fromRow.nodeType == 1 && fromRow.nextSibling != null) { var fRowId = fromRow.id; if (!fRowId) continue; // THIS ONLY gets done once and alerts "row_1" ONLY :( alert(fRowId); fromRow = fromRow.nextSibling; } Ok can someone please tell me what is wrong with this code? There are siblings next to this document.getElementById("row_1"); element for sure as I can see them, and they all have id attributes, so why is it not getting the id attributes of the siblings?? I don't get it. row_1 is a TR element, and I need to get the TR elements next to it within this table, but for some reason, it only gets the 1 element that I can already get using document.getElementById, arggg. Thanks guys :)

However, I don't think I can set the array size after I have declared it. I need it global as some other functions will need to access the device names. Many thanks for any suggestions, /* global */ char *devices_names[]; void fill_devices(size_t num_devices) { devices_names[num_devices]; /* start filling */ }

  • jQuery - Why doesn't combining has() and gt() work in some cases?

    - by KatieK
    I wanted to select any ul which contains more than 3 lis. This code worked with the 1.2.6 jQuery library: $("ul:has(li:gt(2))") .each( function() { $(this).css("border", "solid red 1px"); }); But not 1.3.2 or 1.4.2. This code worked with the 1.4.2 jQuery library: $('ul').has('li:nth-child(3)').css('border', 'solid red 1px'); But not v1.2.6. Why does each version work with one library version, but not the other? Am I encountering some kind of bug, or am I doing something wrong? Any help understanding , or differences to be aware of between different versions of the jQuery libraries, would be much appreciated. Thanks!
