  • jquery mouseover animation jumping

    - by Sylph
    Hi all, I have a table which is looped in <li>. On mouseover each row, there will be a border shown, and the row id="resFunc" will be displayed. However, in IE, the animation jumps up and down. Anyone has similar experience or solution to solve this? Thanks in advance! <div id="resDetails" align="left"> <table width="400px" class="resBox"> <tr> <td><b>{creator}</b></td> </tr> <tr> <td colspan="2"><div class="edit{_id}" id="{_id}"> {title}</div></td> </tr> <tr style="display:none" class="url{_id}"> <td colspan="2" class="edit_url{_id}" id="{_id}">{url}</td> </tr> <tr> <td colspan="2" class="edit_area{_id}" id="{_id}">{description}</td> </tr> <tr id="resFunc{_id}" style="display:none"> <td colspan="2" align="right"><b><a href="#" id="{_id}" class="editRes">Edit</a>&nbsp;&nbsp; <a href="#" class="deleteResource" id="{_id}">Delete</a></b> </td> </tr> </table><br> </div> This is the onClick function :- $(".resBox").mouseover(function(){ var id = $(this).attr("id"); $(this).addClass('highlight'); $('#resFunc'+id).show(); }); $(".resBox").mouseout(function(){ var id = $(this).attr("id"); $(this).removeClass('highlight'); $('#resFunc'+id).hide(); });

  • Override default javascript functionality with jQuery

    - by deth4uall
    I am trying to overwrite a JavaScript on change event in the below code with jQuery however I believe that the inline JavaScript is taking priority over the jQuery functionality declared. Essentially I am trying to have an AJAX version of my site which includes an additional JavaScript file. I need this functionality to still work without the additional AJAX version, but I am not sure as to whether I should include it in the main JavaScript file or leave it inline like it is right now. Any suggestions and information regarding them would be greatly appreciated! Thanks! <form action="/cityhall/villages/" method="post" name="submit_village"> <select name="village" onchange="document.submit_village.submit();"> <option value=""></option> </select> </form> I am trying to use the jQuery Form Plugin to submit the posts to the PHP to handle the requests as follows: var bank_load_options = { target: '#content', beforeSubmit: showRequest, success: showResponse }; $('form.get_pages').livequery(function(){ $(this).ajaxForm(bank_load_options); return false; }); I modified the code as following: <form action="/cityhall/villages/" method="post" id="submit_village" name="submit_village"> <select name="village" class="get_pages" rel="submit_village"> <option value=""></option> </select> </form> <script> # main JavaScript $('.get_pages').live('change',function(e){ var submit_page = $(this).attr('rel'); $("#"+submit_page).submit(); }); # ajax JavaScript var bank_load_options = { target: '#content', beforeSubmit: showRequest, success: showResponse }; $('.get_pages').live('change',function(){ var submit_page = $(this).attr('rel'); $("#"+submit_page).ajaxForm(get_pages_load_options); return false; }); </script> However now it only runs every other option when I change it.

  • PHP Sessions Error

    - by Andrei Korchagin
    I'm new to PHP sessions and I've come across the following error: Warning: session_start() [function.session-start]: Cannot send session cookie - headers already sent by (output started at somefile:someline). As well as this one: Warning: session_start() [function.session-start]: Cannot send session cache limiter - headers already sent by (output started at somefile:someline). The session_start(); is the very first thing in all of my code. I'm not sure what the problem is. It gave me line numbers but all I do on those lines is start the session. Also - I have a portion of code whose POST action is another PHP page. How can I set a $_SESSION variable pertaining to this page within that action page?

  • numpy arange with multiple intervals

    - by Heiko Westermann
    Hi, i have an numpy array which represents multiple x-intervals of a function: In [137]: x_foo Out[137]: array([211, 212, 213, 214, 215, 216, 217, 218, 940, 941, 942, 943, 944, 945, 946, 947, 948, 949, 950]) as you can see, in x_foo are two intervals: one from 211 to 218, and one from 940 to 950. these are intervals, which i want to interpolate with scipy. for this, i need to adjust the spacing, e.g "211.0 211.1 211.2 ..." which you would normaly do with: arange( x_foo[0], x_foo[-1], 0.1 ) in the case of multiple intervals, this is not possible. so heres my question: is there a numpy-thonic way to do this in array-style? or do i need to write a function which loops over the whole array and split if the difference is 1? thanks!

  • How to use unset() for this Linear Linked List in PHP

    - by Peter
    I'm writing a simple linear linked list implementation in PHP. This is basically just for practice... part of a Project Euler problem. I'm not sure if I should be using unset() to help in garbage collection in order to avoid memory leaks. Should I include an unset() for head and temp in the destructor of LLL? I understand that I'll use unset() to delete nodes when I want, but is unset() necessary for general clean up at any point? Is the memory map freed once the script terminates even if you don't use unset()? I saw this SO question, but I'm still a little unclear. Is the answer that you simply don't have to use unset() to avoid any sort of memory leaks associated with creating references? I'm using PHP 5.. btw. Unsetting references in PHP PHP references tutorial Here is the code - I'm creating references when I create $temp and $this-head at certain points in the LLL class: class Node { public $data; public $next; } class LLL { // The first node private $head; public function __construct() { $this->head = NULL; } public function insertFirst($data) { if (!$this->head) { // Create the head $this->head = new Node; $temp =& $this->head; $temp->data = $data; $temp->next = NULL; } else { // Add a node, and make it the new head. $temp = new Node; $temp->next = $this->head; $temp->data = $data; $this->head =& $temp; } } public function showAll() { echo "The linear linked list:<br/>&nbsp;&nbsp;"; if ($this->head) { $temp =& $this->head; do { echo $temp->data . " "; } while ($temp =& $temp->next); } else { echo "is empty."; } echo "<br/>"; } } Thanks!

  • Which event to catch for application shut down?

    - by xueru
    I am using jQueryMobile and phoneGap for a cross-device mobile application. I use html 5 local storage to persist records that worked on by user. I don't know which phoneGap event to catch just before application shut-down so I can make sure data is saved before shutdown completes. Base on suggestion from naughtur, I tried both unload and beforeunload events, neither of them got fired during app shutdown. Following is my code snip: function persistTasks(){ alert ("is unloading the app"); offlineTasklist.set("tasks", tasklist); } function init() { document.addEventListener("unload", persistTasks, false); login(); } $(document).ready(init);

  • Prevent auto scrolling when clicking tab anchor

    - by JohnCrossy
    On my page I have some tabs that I've added some javascript so when they're clicked the page loads the tab's anchor URL instead of simply changing the view with AJAX, but I now want to stop the browser from auto scrolling to the anchor location. Having done some research, I'm pretty sure I just need to add a couple of lines so that when clicked it returns false or prevents default but, being a noob, I've no idea where to put them!?! I know it's cheeky, but if any answers could include the full script (ie. the below) with the solution, that way I'll understand better and hopefully learn some valuable lessons also :) Here's the code I'm using: jQuery( function() { jQuery('.ui-tabs').bind( 'tabsselect', function( e, ui ) { window.location.hash = ui.tab.hash }); });

  • dojo TimeTextBox don't listen to on blur event

    - by kawtousse
    Hi everyone, I want to add an on blur event to a dojo timetextbox but the event never been runned so the declaration of the timetextbox is like this: <label>End</label><input id="endp" name="endp" onBlur="calculateTimeSpent2(startp,endp,output);" /> the javascript function is like this: function calculateTimeSpent2(startp,endp,outputp) { var tmp0=document.getElementById('startp').value.split(':'); var tmp1=document.getElementById('endp').value.split(':'); if (tmp0[0]!='' && tmp1[0]!='') { var val1= findtime(tmp0[0],tmp0[1],tmp1[0],tmp1[1]); var tmp=val1.split(':'); if (tmp[0].indexOf('-')==-1) document.getElementById('outputp').value=val1; else { alert ("Start Time must be lower than End Time "); document.getElementById('endp').focus(); } } } I don't understand why dojo didn't execute the event correctly while loosing the focus. I tried to put the type=text but it does'nt work. Thanks for help.

  • Haskell: Problems with overloading: Interpreter can´t tell which + to use

    - by Ben
    Hi, I want to make functions Double - Double an instance of the Num typeclass. I want to define the sum of two functions as sum of their images. So I wrote instance Num Function where f + g = (\ x - (f x) + (g x)) Here the compiler complains he can´t tell whether I´m using Prelude.+ or Module.+ in the lambda expression. So I imported Prelude qualified as P and wrote instance Num Function where f + g = (\ x - (f x) P.+ (g x)) This compiles just fine, but when I try to add two functions in GHCi the interpreter complains again he can´t tell whether I´m using Prelude.+ or Module.+. Is there any way I can solve this problem?

  • What is the most efficient algorithm for reversing a String in Java?

    - by Hultner
    I am wondering which way to reverse a string in Java that is most efficient. Should I use some sort of xor method? The easy way would be to put all the chars in a stack and put them back into a string again but I doubt that's a very efficient way to do it. And please do not tell me to use some built in function in Java. I am interested in learning how to do it not to use an efficient function but not knowing why it's efficient or how it's built up.

  • Javascript, how do you sort an array on multiple columns?

    - by flavour404
    Hi, I have a multidimensional array, the primary array is an array of [publicationID][publication_name][ownderID][owner_name]. What I am trying to do is sort the array by owner name and then by publication_name. I know in JavaScript you have Array.sort(), into which you can put a custom function, in my case i have: function mysortfunction(a, b) { var x = a[3].toLowerCase(); var y = b[3].toLowerCase(); return ((x < y) ? -1 : ((x > y) ? 1 : 0)); } This is fine for just sorting on the one column, namely owner_name, but how do I modify it to sort on owner_name, then publication_name? Thanks, R.

  • getjson alternative method for variable

    - by Florian Stanek
    I made a script which gets the data from a json file and parse it. It worked on a webserver. But now I have to find a solution to get it work on a local file (file:///C:/xampp/htdocs/script/index.html) instead on a server. It only works in FF: $.getJSON('data2.json', function(data) { $.each(data.selection_form.entities, function(i,name){ ...do something }); }); Any ideas? A local webserver is not a solution.

  • C++ static virtual members?

    - by cvb
    Is it possible in C++ to have a member function that is both static and virtual? Apperantly, there isn't a straight-forward way to do it (static virtual member(); is a complie error), but at least a way to acheive the same effect? I.E: struct Object { struct TypeInformation; static virtual const TypeInformation &GetTypeInformation() const; }; struct SomeObject : public Object { static virtual const TypeInformation &GetTypeInformation() const; }; It makes sence to use GetTypeInformation() both on an instance (object->GetTypeInformation()) and on a class (SomeObject::GetTypeInformation()), which can be useful for comparsions and vital for templates. The only ways I can think of involves writing two functions / a function and a constant, per class, or use macros. Any other solutions?

  • Stopping jQuery Jumping to Newly Loaded Content.

    - by Damien
    I have a div with is replaced upon certain user actions. These actions are performed under the div that is being replaced and in the case that the div is too large to fit completely into the view window, along with the buttons used to change it underneath, the browser will jump to the top of the newly loaded div. Which is annoying. Does anyone know of a way to stop these? Cheers. Here is the jQuery code. ChartContent is a small blob of html function UpdateChartImage(ChartContent) { //do updates on div here var existingChart = $("#" + $(ChartContent).attr("id")); existingChart.fadeOut("fast", function() { existingChart.replaceWith(ChartContent); }).fadeIn("fast"); } Incidentally I have prevented the button from doing it's default behaviour so I don't think it's related to that.
