  • How do I load the background image from another page?

    - by bbeckford
    Hi all, I'm creating a page that loads content from other pages using jQuery like this: $('#newPage').load('example.html' + ' #pageContent', function() { loadComplete(); }); That all works fine. Now what I want to do is change the background image of the current page to the background image of the page I'm loading from. This is what I'm doing now but I can't for the life of me get it to work: $.get('example.html', function(data) { var pageHTML = $(data); var pageBody = pageHTML.$('body'); alert(pageBody.attr("background")); }); What am I doing wrong?? Thanks, -Ben

  • Javascript/jQuery: remove shape/path from canvas

    - by bobsoap
    I can't seem to find the function to remove a shape or path from the canvas after it has been created. So I'm creating a bezier curve between 2 points with beginPath(); bezierCurveTo(); stroke(); closePath(); . How can I remove this from the canvas once it's been created? I need to be able to call the remove function via toggle() and blur(). I'm sure something exists for this... Thanks in advance for any help!

  • How to recover from a fatal error "Allowed memory size exhausted"

    - by Matthieu
    Hi everybody, Do you know any solution to recover from the PHP fatal error : "Allowed memory size ... exhausted" I have a shutdown function that is called when a fatal error appear. This function create an ErrorException from it, and logs it. The problem is : when there is no more memory available, it can't log the error (I log in Firebug, via FirePHP, with Zend Framework). So what i mean by "how to recover from it", is how to perform basic error log, and let Zend Framework send the Headers, so that the error is logged (in Firebug in my case) as any other error ? Thanks

  • jQuery - Animation flicker using hover()

    - by Chris
    I have a setup as described in this question which works perfectly. Essentially a drop down menu grows when you move your mouse over it to expose more options. There is, however, a small issue. If you move the mouse outside of the #dropdown div and then back in again quickly it constantly fires the mouseenter and mouseleave events causing a never ending cycle of flickering. How can I get around it? Here is my current jQuery code $("#dropdown").hover(function() { $(this).stop(true,true).fadeTo('fast',1); $("#options").stop(true,true).slideDown(); }, function() { $(this).stop(true,true).fadeTo('fast',0.1); $("#options").stop(true,true).slideUp(); } );

  • Cookie is setting twice (dublicated)

    - by Erik Larsson
    I'm new to cookies, and im trying to set a cookie where to store the referer (the org ref). But when i try this function: function do_it_cookie() { // Check if cookie exists if (isset($_COOKIE['ref'])) { // It dose exist, do nothing or anything... } else { setcookie ('ref', $_SERVER['HTTP_REFERER'], time() + 60, '/'); header ("Location: http://www.nyttforetag.com/mind-your-own-business/"); } } I want to store the cookie on the user computer for 30 days, if the return i want to know the initial refereeing url. But when i use this and lets say i go to another page in my site and then go back to the homepage its sets a new cookie with the exact same name and with the ref of the previous page. Is there away to avoid this?

  • Syntax error while copying an multidimensional array to another in C

    - by mantuko
    We are programming a ST269 microcontroller which has two IR distance sensors. To calibrate these sensors we made one table for each sensor with the distance we measured and the corresponding value we get from the ADC. Now we want to use one function to approximate the values in between. So we defined two two-dimensional arrays (one for each sensor) as global variables. In our function we then want to copy the one array we want to work with to a working array and approximate our values. So here's the code: ... unsigned int ir_werte_re[][] = { {8,553}, ... {83,133} }; unsigned int ir_werte_li[][] = { {8,566}, ... {83,147} }; ... unsigned int geradenaproximation(unsigned int messwert, unsigned int seite) { unsigned int working_array[16][16]; unsigned int i = 0; if (seite == 0) { for (i = 0; i < sizeof(working_array); i++) { working_array[i][0] = ir_werte_li[i][0]; i++; } } else { for (i = 0; i < sizeof(working_array); i++) { working_array[i][0] = ir_werte_re[i][0]; i++; } } i = 0; unsigned int y1 = 0; unsigned int x1 = 0; ... } This code is in a file called sensor.c. We didn't write anything about our global arrays in the sensor.h should we? The sensor.h of course is included in our main.c and there the function is called. We also tried to copy the arrays via memcpy(working_array, ir_werte_li, sizeof(working_array)); And in every way we do this we get a syntax error near unsigned in the line where we're declaring unsigned int y1 = 0; and I'm pretty sure that there is no syntax error in this line : ) The last time I spend coding in C is a few years away so I'm not sure if the way we try to do this is good. Perhaps we can solve this by using a pointer instead of really copying the array or something. So please help me out I'll appreciate your bits on this.

  • MooTools Problem in IE with Request

    - by trobrock
    I have this class method in a mootools class: getData : function(){ var r = new Request.JSON({ url : this.container.getAttribute('data-url'), method : 'post', onSuccess : function(j){ this.cards = j; this.prepareQuiz(); }.bind(this) }).send(); }, In any browser aside from IE this works fine, but in IE I get a this.cards is not defined in a method that occurs after the this.prepareQuiz method does it's stuff. I narrowed the problem to this section by adding an if ($defined(this.cards)) before the this.prepareQuiz call and if I just keep refreshing the page 1 out of every 5 or so times it will work. So the this.cards variable is not being set some of the time for some reason. Why would this happen?

  • Image Preloading in Canvas

    - by smokinguns
    I'm drawing an Image on the canvas using the drawImage function. This is how Im setting the src property of the image: var img = new Image(); // Create new Image object img.src = 'test.php?filename=myfile.jpg' and then oCanvas.width = 600; oCanvas.height = 400; oContext.drawImage(img, 0, 0, 600, 400); The problem is that if the src isn't set then I get the foll error:"uncaught exception: [Exception... "Component returned failure code: 0x80040111 (NS_ERROR_NOT_AVAILABLE) [nsIDOMCanvasRenderingContext2D.drawImage]" . I know I get this error coz the image hasnt finished loading. I added an alert just before the call to drawImage function to let the image finish loading and it seems to work. But it's a pain in the neck. How do I check if the image has finished loading? BTW I have to set the src property by calling a php file.

  • Parse Domain from a given URL in T-SQL

    - by Adam N
    I fount this answer, but wanted to expand on the question and couldn't find any solutions here on stack or through searching google. Substring domainname from URL SQL Basically the link above solves my problem with a simple URL like parsing "www.google.com" with the result of google. What I am looking for to expand on that is the solution from the link above doesn't help with url's like 'www.maps.google.com' that just returns maps. WHat I would like is to have it return 'google' from the url 'www.maps.google.com' or return 'example' from 'www.test.example.com'. If anyone has a solution to this, I would greatly appreciate it. Update: To be more specific I will also need parsing on second level domains etc. 'www.maps.google.com.au' to return 'google' Here is my Sql function. CREATE FUNCTION [dbo].[parseURL] (@strURL varchar(1000)) RETURNS varchar(1000) AS BEGIN IF CHARINDEX('.', REPLACE(@strURL, 'www.','')) > 0 SELECT @strURL = LEFT(REPLACE(@strURL, 'www.',''), CHARINDEX('.',REPLACE(@strURL, 'www.',''))-1) Else SELECT @strURL = REPLACE(@strURL, 'www.','') RETURN @strURL END

  • show the list of usernames inside a div

    - by Mr_Green
    I am new to jQuery. In my project, I created one Class User in which the code is as shown below: static ConcurrentDictionary<string, User> _users = new ConcurrentDictionary<string, User>(); // // some function to add values to _users list // public List<User> GetConnectedUsers() { return _users.Values.ToList(); } I want to show this list of values in div #showUsernames. How to do this by using jQuery? I tried the below which is not showing anything /*display your contacts*/ $('#showUsernames').append(function(){ chat.server.getConnectedUsers(); }); where chat.server(signalr) calls the server-side code(Chat class).. I think the solution has nothing to do with signalr. If the above description is not enough then you can go through my code here

    - by aspdotnetuser
    Hi, I want to call a webservice using jQuery.ajax() but the webervice doesn't get called. - If I change the url: to reference a .ashz file it gets called but not .asmx? Here's the code I'm using: jQuery.ajax({ type: "POST", url: "/services/CheckUsername.asmx/CheckUsername", // this doesn't get called //url: "/services/CheckUsername.ashx/ProcessRequest", this gets called data: '{ "context": "' + "username" + '"}', contentType: 'application/json; charset=utf-8', dataType: 'json', success: function (msg) { alert("Result: " + msg); }, error: function (XMLHttpRequest, textStatus, errorThrown) { alert("Error: " + textStatus) } The .ashz file gets called but a parsererror is retuned because it's returning http context - how can I modify this to get a string return type from a webservice? Thanks,

  • How to determine the inner context node within an XSLT select

    - by Marcus Rickert
    Hi there! I'm trying to determine a subset of nodes stored in the variable objs by using a user defined function cube:is_active: <xsl:variable name="active_cubes" select="$objs[cube:is_active(XXX) = 'TRUE']"/ Since the function does not allow a local context I'm required to pass it as a parameter (denoted by XXX). However, the usual suspects "." or "current()" do not work since they refer to context node of the surrounding block and NOT to the current element of objs which is evaluated. The only solution so far which DOES work is: XXX=SOME_CHILD_TAG/.. But this is really ugly since it depends on the existence of the child tag for the parent node to work correctly. Is there any other way? Thanks!

  • How do I use Declarations (type, inline, optimize) in Scheme?

    - by kunjaan
    How do I declare the types of the parameters in order to circumvent type checking? How do I optimize the speed to tell the compiler to run the function as fast as possible like (optimize speed (safety 0))? How do I make an inline function in Scheme? How do I use an unboxed representation of a data object? And finally are any of these important or necessary? Can I depend on my compiler to make these optimizations? thanks, kunjaan.

  • search submitbutton in all forms with textareas with jquery

    - by domueni
    Hi there i'm working on a ff-plugin which searchs a webpage for all textareas and places a warning before the submit button. my code looks like this var submitWarning = content.document.createElement("div"); submitWarning.innerHTML = "Fancy Message"; $('textarea', window.content.document).each(function() { var form = $(this, window.content.document).parents('form:first'); $(form, window.content.document).children('input[type=submit]').each(function() { form.insertBefore(submitWarning, this); }); }); if i search all submits with $('input[type=submit]'.each... it works fine but since i added the thing with the textarea and the form:first i got problems (nothing happens) p.s. i use the window.content.document thingy because its a ff-plugin and it won't work nothing without it

  • Referencing other modules in atexit

    - by Dmitry Risenberg
    I have a function that is responsible for killing a child process when the program ends: class MySingleton: def __init__(self): import atexit atexit.register(self.stop) def stop(self): os.kill(self.sel_server_pid, signal.SIGTERM) However I get an error message when this function is called: Traceback (most recent call last): File "/usr/lib/python2.5/atexit.py", line 24, in _run_exitfuncs func(*targs, **kargs) File "/home/commando/Development/Diploma/streaminatr/stream/selenium_tests.py", line 66, in stop os.kill(self.sel_server_pid, signal.SIGTERM) AttributeError: 'NoneType' object has no attribute 'kill' Looks like the os and signal modules get unloaded before atexit is called. Re-importing them solves the problem, but this behaviour seems weird to me - these modules are imported before I register my handler, so why are they unloaded before my own exit handler runs?

  • Modulation of adding new Strings -> Method calls.

    - by guesswork
    If I have a program that does the following: if(input=='abc'){do x} if(input=='def'){do y} In the future, I may want to add another piece of code like so: if(input=='ghy'){do x} As you can see, I am adding a new 'if' statement for a different conditional BUT using the SAME function X. The code in future has potential to have lots of different IF statements (or switches) all of which are comparing a string vs a string and then performing a function. Considering the future expansion, I was wondering if there is a possible 'neater', 'modular' way of achieving the same results. It's a shame I can't combine the String with a Method call in a hashtable (String, method) in Java. That way I could just store any new procedures inside a hashtable and grab the relevant method for that String. Any ideas? Thank you

  • validation functions in google apps script is not working properly

    - by chocka
    I create a i/p form in google site using Apps Script and i did the validation using the Apps Script coding. Validation functions available in Apps script is not satisfying all the possibility of checking the error. function validate(e) { var app = UiApp.getActiveApplication(); var flag=0; var text = app.getElementById('name'); var textrequired = app.getElementById('namerequired'); var number = app.getElementById('number'); var numberrequired = app.getElementById('numberrequired'); var email = app.getElementById('email'); var emailrequired = app.getElementById('emailrequired'); var submit = app.getElementById('submit_button'); var valid = app.createClientHandler() .validateNumber(number) .validateNotInteger(text) .validateEmail(email) .forTargets(submit).setEnabled(true) .forTargets(number,text,email).setStyleAttribute("color","black") .forTargets(numberrequired,textrequired,emailrequired).setText('*').setStyleAttribute("color", "red").setVisible(true); var invalidno = app.createClientHandler().validateNotNumber(number).validateMatches(number, '').forTargets(number).setStyleAttribute("color", "red").forTargets(submit).setEnabled(false).forTargets(numberrequired).setText('Please Enter a Valid No.').setStyleAttribute("color", "red").setVisible(true); var validno = app.createClientHandler().validateNumber(number).forTargets(number).setStyleAttribute("color","black").forTargets(numberrequired).setText('*').setStyleAttribute("color", "red").setVisible(true); var invalidText=app.createClientHandler().validateNumber(text).validateMatches(text, '').forTargets(text).setStyleAttribute("color", "red").forTargets(submit).setEnabled(false).forTargets(textrequired).setText('Please Enter a Valid Name.').setStyleAttribute("color", "red").setVisible(true); var validText=app.createClientHandler().validateNotNumber(text).forTargets(text).setStyleAttribute("color","black").forTargets(textrequired).setText('*').setStyleAttribute("color", "red").setVisible(true); var invalidemail=app.createClientHandler().validateNotEmail(email).validateMatches(email, '').forTargets(email).setStyleAttribute("color", "red").forTargets(submit).setEnabled(false).forTargets(emailrequired).setText('Please Enter a Valid Mail-Id.').setStyleAttribute("color", "red").setVisible(true); var validemail=app.createClientHandler().validateEmail(email).forTargets(email).setStyleAttribute("color","black").forTargets(emailrequired).setText('*').setStyleAttribute("color", "red").setVisible(true); number.addKeyPressHandler(invalidno).addKeyPressHandler(validno).addKeyPressHandler(valid).addKeyPressHandler(invalidText).addKeyPressHandler(invalidemail); text.addKeyPressHandler(invalidText).addKeyPressHandler(validText).addKeyPressHandler(valid).addKeyPressHandler(invalidno).addKeyPressHandler(invalidemail); email.addKeyPressHandler(invalidemail).addKeyPressHandler(validemail).addKeyPressHandler(valid).addKeyPressHandler(invalidno).addKeyPressHandler(invalidText); if (text == ''){flag = 1;} if (email == ''){flag = 1;} if (number == ''){flag = 1;} if(flag == 1){submit.setEnabled(false);} return app; } I just placed my Validation function using Apps Script. I don't know why its not satisfying all the possibilities of the validation. And also i have to do is to enable the submit button after all the fields satisfy the validation. After once it enabled, if i make any error in any field it will not get disable correctly. I wrote the coding correctly i think so. Please take a look at my validation function and give me some suggestion to make it possible. Please guide me, Thanks & Regards, chocka.

  • How to I count key collisions when using boost::unordered_map?

    - by Nikhil
    I have a data structure with 15 unsigned longs, I have defined a hash function using hash_combine as follows: friend std::size_t hash_value(const TUPLE15& given) { std::size_t seed = 0; boost::hash_combine(seed, val1); boost::hash_combine(seed, val2); ... return seed; } I insert a large number of values into a boost::unordered_map but the performance is not good enough. Probably, I could do better with an alternative hashing function. To confirm this, I need to check how many collisions I am getting. How do I do this?

  • Pushing notifications to a JavaScript?

    - by Michael Stum
    I'm just wondering if there is a way to have a server push information to a JavaScript function. Essentially I have a Dashboard-type page that has a javaScript function to get updates from the server and update the dashboard. I would like my server to be able to "ping" the JS. I don't even know how that could be possible (I'm guessing Twitter and Facebook use polling?), but I'd thought I ask. I heard of Comet, but I don't know if that works with a plain standard IIS 7 installation? (It's a SharePoint 2010 site if that matters in any way) If I understand it correctly, Comet is essentially a constantly open connection, so it seems like it's actually the opposite of what I want (reducing # of requests and therefore load)

  • how to handle exceptions/errors in php?

    - by fayer
    when using 3rd part libraries they tend to throw exceptions to the browser and hence kill the script. eg. if im using doctrine and insert a duplicate record to the database it will throw an exception. i wonder, what is best practice for handling these exceptions. should i always do a try...catch? but doesn't that mean that i will have try...catch all over the script and for every single function/class i use? Or is it just for debugging? i don't quite get the picture. Cause if a record already exists in a database, i want to tell the user "Record already exists". And if i code a library or a function, should i always use "throw new Expcetion($message, $code)" when i want to create an error? Please shed a light on how one should create/handle exceptions/errors. Thanks

  • PHP: How to overwrite values in one array with values from another

    - by Svish
    I have an array with default settings, and one array with user-specified settings. I want to merge these two arrays so that the default settings gets overwritten with the user-specified ones. I have tried to use array_merge, which does the overwriting like I want, but it also adds new settings if the user has specified settings that doesn't exist in the default ones. Is there a better function I can use for this than array_merge? Or is there a function I can use to filter the user-specified array so that it only contains keys that also exist in the default settings array? (PHP version 5.3.0)
