  • send javaScript variable to php variable

    - by mrbunyrabit
    First i thought that i had to convert javascript to php, but then i found out that cant because of server and client side executions. So now I simply want to send ONE variable <script type="text/javascript"> function scriptvariable() { var theContents = "the variable"; } </script> to a php variable <?php $phpvariable ?> That function in the javascript executes when lets say i click on a button. Now i have Nooo idea how to get that phpvariable Equal to the javascript one so i can use that phpvariable to look up stuff in my Database. I know i can add it to my url or some thing, and just refresh the page.. But id like to do it with AJAX as further in my webpage i might have to use this Ajax method.. So is there an easy way to do this without having to dump pages of code on my page to do one simple thing?

  • returning null or throwing an exception?

    - by MoKi
    I have the following types: typedef QPair < QTime , QTime > CalculatedTimeSlotRange; typedef QList < CalculatedTimeSlotRange > CalculatedTimeSlotRangeList; typedef QHash < quint8 , CalculatedTimeSlotRangeList > TimeSlotsTable; I have a function like the following: const CalculatedTimeSlotRangeList* TimeSlots::getCalculatedTimeSlotRangeList(const quint8 id) const { QHashIterator<quint8,CalculatedTimeSlotRangeList> it(mTimeSlotsTable); while (it.hasNext()) { it.next(); if(it.key() == id) { return &it.value(); } } return NULL; } as you can see my function returns a null if it fails to find a key that matches id. Is this correct? or should I just throw an exception if the key does not exist? how should i throw an exception for this situation?

  • Extract data from uint8 to double

    - by HADJ AMOR HASSEN
    I have a C function receiving a uint8 pointer with another parameter which is its size (number of bytes). I want to extract double data from this buffer. Here is my code: Write(uint8* data, uint8 size) /* data and size are given by a callback to my function)*/ { double d; for (i = 0; i < size; i++) { d = ((double*)&data)[i]; printf(" d = %d\n"); } } The problem is that I am not receiving what I am sending within an external hardware. I guess that my cast is wrong. I tried other methods but without any good result. I am still not able to get what I send.

  • overriding callbacks avoiding attribute pollution

    - by pygabriel
    I've a class that has some callbacks and its own interface, something like: class Service: def __init__(self): connect("service_resolved", self.service_resolved) def service_resolved(self, a,b c): ''' This function is called when it's triggered service resolved signal and has a lot of parameters''' the connect function is for example the gtkwidget.connect, but I want that this connection is something more general, so I've decided to use a "twisted like" approach: class MyService(Service): def my_on_service_resolved(self, little_param): ''' it's a decorated version of srvice_resolved ''' def service_resolved(self,a,b,c): super(MyService,self).service_resolved(a,b,c) little_param = "something that's obtained from a,b,c" self.my_on_service_resolved(little_param) So I can use MyService by overriding my_on_service_resolved. The problem is the "attributes" pollution. In the real implementation, Service has some attributes that can accidentally be overriden in MyService and those who subclass MyService. How can I avoid attribute pollution? What I've thought is a "wrapper" like approach but I don't know if it's a good solution: class WrapperService(): def __init__(self): self._service = service_resolved # how to override self._service.service_resolved callback? def my_on_service_resolved(self,param): ''' '''

  • Visibility of elements by ID

    - by dragonfly
    Hi, how come that when I attach onchange by attribute and call it onchange="validateDate(FPR_CURR_FROM);" it works, but when I use a ASP .NET validator, and my attached function is called like : function anonymous() { ValidatorOnChange(event); validateDate(FPR_CURR_FROM); } I get error: FPR_CURR_FROM is undefined. First off: I know that using FPR_CURR_FROM to access element is BAD, and I should use getElementByID etc... And I will change it eventually. But as I bumped into that code, I'm curious what caused it - propably visibility of variables I guess.

  • Why is order important in moving from tab to tab programmatically (and new in 1.8.10

    - by Bruce
    Hi folks, Up until I updated to jquery-ui-1.8.10 (already using jQuery 1.5), the following code has worked as expected: case 'baseeditor': $('#tab1').html(responseText).fadeIn(500, function() { ... load the contents of the tab and stuff... }); $("#prolearn").tabs("select",1); break; case ... The tab is fueled and then focus is moved from tab0 (from where the ajax call is initiated) to tab1. Now, that code won't work, but this version does: case 'baseeditor': $("#prolearn").tabs("select",1); $('#tab1').html(responseText).fadeIn(500, function() { ... load the contents of the tab and stuff... }); break; case ... Can someone explain the difference - have I just been lucky getting away with my original version? Thanks/Bruce

  • Prevent Excel from evaluating unneeded expressions in OR()

    - by Wesley
    IF(OR(ISNA(MATCH(8,B10:B17,0)),MATCH(8,B10:B17,0)>8),"",...BLAH...) I understand how to fix this problem by rearranging my formula. I have it the way it is to show this point. You can see the OR() statement checks to see if the first MATCH() returns NA. When it does, OR() should automatically return TRUE and not evaluate the second MATCH() because conditions have been met for the OR() to return true no matter what other arguments there are. You'll notice that the first and second MATCH() functions do the same thing. What's happening is the entire function is returning NA because the second MATCH() is executing even though it doesn't have to, the OR() has been satisfied with one TRUE, therefore the function should return "". Is this a bug or is this intentional?

  • Changing cell class on radio button change

    - by Nick
    Huge thanks for the help in this thread - Click td, select radio button in jQuery But now I'm having trouble that it won't change the class of the cell, even though I have binded the 'change' trigger in jQuery like so: $("td input[type=radio]").bind('change click', function () { $('td').removeClass('selected'); $(this).parent('td').addClass('selected'); }); $("td").click(function () { $('input:radio', this).attr('checked', true); }); Hope that makes sense. If you click the radio button, or move between them using the keyboard, the cell's class changes just fine. However if you trigger this by clicking the cell it doesn't change the class :( Thanks

  • How to pass a const unsigned char * from c++ to c#

    - by tzup
    So I have a function in unmanaged c++ that gets called when some text happens to have "arrived": #using <MyParser.dll> ... void dump_body(const unsigned char *Body, int BodyLen) { // Need to pass the body to DumpBody, but as what type? ... lMyParser::Parser::DumpBody(???); } DumpBody is a function defined in a C# DLL that should take one parameter of type? Body holds an array of characters (text) of length BodyLen. There's obviously some marshalling to be done here but I have no idea how. Please help.

  • Python: How to use code.InteractiveConsole?

    - by Rosarch
    I'm trying to use InteractiveConsole to create a new front-end for a Python interpreter. These code fragments are from me playing around with InteractiveConsole in IDLE: >>> ses = code.InteractiveConsole() >>> ses.runsource("def foo():") True >>> ses.runsource(" return 2") File "<input>", line 1 SyntaxError: 'return' outside function (<input>, line 1) False Why does it raise a syntax error? How else can I finish writing the function? Also, for something like this: >>> ses.runsource("x = 1") False >>> ses.runsource("x") 1 False How can I capture the 1 value from above? False is the return value, but 1 is written to some stream.

  • Defautlt Contoller in CodeIgniter

    - by gregavola
    Hello everyone, I am wondering if there is any other configuration options for a default controller. For example - if I have a controller called "site" and I set the default controller in the following file: application/config/routes.php to: $route['default_controller'] = "site"; I should be able to go to http://localhost and that brings up the index(); function in the site controller. However, if I try to do go to http://localhost/index.php/index2 to load the index2(); function I get a 404 error. If i change the URL to http://localhost/index.php/site/index2 it works fine - but I thought already set the default controller. Is there any way around this? Any thoughts?

  • jQuery animate slidding background image using mouse position wont stop... just keeps going

    - by simian
    I have a neat little jQuery script I am working on. Goal: parent div with overflow hidden holds a larger div with image. When I move the mouse to the left or right of the parent div, the div with image changes margin-left to move left or right. Problem is... if I move the mouse out of the parent div (left or right), the image keeps going. I need the image to stop when the mouse is not on the inside left or right edge of the parent div. Any ideas? <!DOCTYPE html> <html xmlns="http://www.w3.org/1999/xhtml"> <head> <meta http-equiv="Content-Type" content="text/html; charset=utf-8" /> <script type="text/javascript" src="http://code.jquery.com/jquery-latest.js"></script> <script type="text/javascript"> //<![CDATA[ jQuery.noConflict (); jQuery(document).ready(function(){ jQuery('#container').mousemove(function(e){ var parentWidth = jQuery('#container').width(); var parentWidthLeft = Math.round(.1 * jQuery('#container').width()); var parentWidthRight = Math.round(jQuery('#container').width() - parentWidthLeft); var parentHeight = jQuery('#container').height(); var parentOffset = jQuery('#container').offset(); var X = Math.round(e.pageX - parentOffset.left); var Y = Math.round(e.pageY - parentOffset.top); if (X<parentWidthLeft) { jQuery('#image').animate({'left': '-' + parentWidth }, 5000); } if (X>parentWidthRight) { jQuery('#image').animate({'left': parentWidth }, 5000); } if (X<=parentWidthRight && X>=parentWidthLeft) { jQuery('#image').stop(); } if (X<1) { jQuery('#image').stop(); } }); jQuery('#container').mouseleave(function(){ jQuery('#image').stop(); }); }); // ]]> </script> </head> <body> <div id="container" style="width: 500px; height: 500px; overflow: hidden; border: 10px solid #000; position: relative; margin: auto auto;"> <div id="image" style="position: absolute; left: 0; top: 0;"><img src="http://dump4free.com/imgdump/1/Carmen-Electra_1wallpaper1024x768.jpg" alt="" /></div> </div> </body> </html>

  • Tabs.url is undefined

    - by Notionwork
    I have no clue what I'm doing wrong here! This should be working I believe. I'm writing a chrome extension and this should get the current tab's url and set the html of #current-tab to the url (for testing purposes). The code successfully gets to the callback, but it says that tab.url is undefined when I put it in an alert box, and it does not put it's value in #current-tab. Here's the code I have: $('#get-tab').click(function(){ chrome.tabs.query({"active" : true}, function(tab){ for (var i = 0; i < tab.length; i++) { alert(tab.url); $('#current-tab').append(tab.url); }; }); });

  • refactor this javascript code

    - by nathanvda
    I have two click-events, that are nearly similar, but not quite. I am wondering how to refactor them best: $('.remove_fields.dynamic').live('click', function(e) { var $this = $(this); var after_removal_trigger_node = $this.closest(".nested-fields").parent(); trigger_removal_callback($this); e.preventDefault(); $this.closest(".nested-fields").remove(); trigger_after_removal_callback(after_removal_trigger_node); }); $('.remove_fields.existing').live('click', function(e) { var $this = $(this); var after_removal_trigger_node = $this.closest(".nested-fields").parent(); trigger_removal_callback($this); e.preventDefault(); $this.prev("input[type=hidden]").val("1"); $this.closest(".nested-fields").hide(); trigger_after_removal_callback(after_removal_trigger_node); }); As you can tell there is a fair bit of overlap. I am wondering what the best/nicest way would be to refactor this code.

  • What's the deal with a leading underscore in PHP class methods?

    - by nocash
    While looking over various PHP libraries I've noticed that a lot of people choose to prefix some class methods with a single underscore, such as public function _foo() ...instead of... public function foo() I realize that ultimately this comes down to personal preference, but I was wondering if anyone had some insight into where this habit comes from. My thought is that it's probably being carried over from PHP 4, before class methods could be marked as protected or private, as a way of implying "do not call this method from outside the class". However, it also occurred to me that maybe it originates somewhere (a language) I'm not familiar with or that there may be good reasoning behind it that I would benefit from knowing. Any thoughts, insights and/or opinions would be appreciated.

  • Simple Search and Replace use of Regular Expression

    - by nunos
    So, I am adapting some code I found online to suit my needs. However, my set_pixel function has two more parameters. Since there are lots of calls to this function even doing a quick paste over would be very tedious. So, I thought this would be a good time for me to learn some simple regular expressions. So, I have calls of this type: set_pixel(arg1, arg2); which I want to change to something like: set_pixel(arg1, arg2, arg3, arg4); Note: arg1 and and 2 should be preserved, whereas arg3 and arg4 are most of the time the same. How can I achieve this?

  • Can I get.seed() somehow?

    - by a different ben
    In reference to the statement set.seed(), can I get the seed instead after running some code if I didn't set it explicitly? I've been re-running some code containing a function that randomises some sample of the input data (the function is part of the kohonen package). After playing with it for some time to see the variety of output (it was an 'unstable' problem), I noticed one result that was pretty interesting. I of course had not used set.seed(), but wondered if I could get the seed after running the code to reproduce the result? In ?set.seed I see .Random.seed saves the seed set for the uniform random-number generator But I don't know how that helps.

    It takes about minute to achieve 3000 in my comp but I need to know the millionth number in the serie. The definition is recursive so I cannot see any shortcuts except to calculate everything before the millionth number. How can you fast calculate millionth number in the serie? Serie Def n_{i+1} = \floor{ 3/2 * n_{i} } and n_{0}=2. Interestingly, only one site list the serie according to Goolge: this one. Too slow Bash code #!/bin/bash function serie { n=$( echo "3/2*$n" | bc -l | tr '\n' ' ' | sed -e 's@\\@@g' -e 's@ @@g' ); # bc gives \ at very large numbers, sed-tr for it n=$( echo $n/1 | bc ) #DUMMY FLOOR func } n=2 nth=1 while [ true ]; #$nth -lt 500 ]; do serie $n # n gets new value in the function throught global value echo $nth $n nth=$( echo $nth + 1 | bc ) #n++ done
