  • Jquery Google Maps Problem

    - by Matias
    Here is the problem: Lets say a Jquery toggle button which loads a Google Map upon request and hides its later when toggled: $('#showmeMap').toggle(function() { var map = new GMap2($("#map").get(0)); var mapCenter = new GLatLng(-2, 20); map.setCenter(mapCenter, 12); $('#map').show(); } }, function() { $('#map').hide(); }); Then I add some random markers and later another function which removes markers from the map: $('#destroyMarkersButton').click(function() { for (var i=0; i<gmarkers.length; i++) { map.removeOverlay(gmarkers[i]); } }); When clicking on the button I´ve got the error Map is undefined. My thought was defining Google Map object globally: map = new GMap2($("#map").get(0)); Which works perfectly in Firefox, however, map fails to load on internet explorer!! Any suggestions ?

  • JQuery transition animation

    - by kk-dev11
    This program randomly selects two employees from a json-object Employees array, winnerPos is already defined. For better user experience I programmed these functions to change pictures one by one. The animation stops when the randomly selected person is shown on the screen. The slideThrough function will be triggered when the start button is pressed. function slideThrough() { counter = 0; start = true; clearInterval(picInterval); picInterval = setInterval(function () { changePicture(); }, 500); } function changePicture() { if (start) { if (counter > winnerPos) { setWinner(); start = false; killInterval(); } else { var employee = Employees[counter]; winnerPic.fadeOut(200, function () { this.src = 'img/' + employee.image; winnerName.html(employee.name); $(this).fadeIn(300); }); counter++; } } } The problem is the animation doesn't work smoothly. At first it works, but not perfect. The second time the transition happens in an irregular way, i.e. different speed and fadeIn/fadeOut differs from picture to picture. Could anyone help me to fine-tune the transition?

  • Javascript: setTimeout() - help needed

    - by ilkin
    Hi guys, I'm currently doing a highlighting function on a webpage and im using the jquery plugin for that. My code looks like this: var input = function() { var matchword = $('#searchbox').val(); if(matchword != "") { $('body').removeHighlight(); $('body').highlight($('#searchbox').val()); } } $(document).ready(function() { $('#searchbox').keyup(function() { setTimeout("input()", 2000); }); }); It works fine if there is not so large amount of data on the page. But in case of large amount of data on the page the whole process is slowing down which causes that inputbox is freezing untill the letter is hightlighted. So the typing is not smooth. I tryed to use a setTimeout but it seems doesnt help. Any ideas?

  • Jquery: Incrimentation for each set of elements in more than 1 div

    - by Jack
    I'm making a Jquery slideshow. It lists thumbnails, that when clicked on, reveal the large image as an overlay. To match up the thumbs with the large images I'm adding attributes to each thumbnail and large image. The attributes contain a number which matches each thumb to its corresponding large image. It works when one slideshow is present on a page. But I want it to work if more than one slideshow is present. Here's the code for adding attributes to thumbs and large images: thumbNo = 0; largeNo = 0; $(this + '.slideshow_content .thumbs img').each(function() { thumbNo++; $(this).attr('thumbimage', thumbNo); $(this).attr("title", "Enter image gallery"); }); $(this + '.slideshow_content .image_container .holder img').each(function() { largeNo++; $(this).addClass('largeImage' + largeNo); }); This works. To make the incrementation work when there are two slideshows on a page, I thought I could stick this code in an each function... $('.slideshow').each(function() { thumbNo = 0; largeNo = 0; $(this + '.slideshow_content .thumbs img').each(function() { thumbNo++; $(this).attr('thumbimage', thumbNo); $(this).attr("title", "Enter image gallery"); }); $(this + '.slideshow_content .image_container .holder img').each(function() { largeNo++; $(this).addClass('largeImage' + largeNo); }); }); The problem with this is that the incrimenting operator does not reset for the second slideshow div (.slideshow), so I end up with thumbs in the first .slideshow div being numbered 1,2,3 etc.. and thumbs in the second .slideshow div being numbered 4,5,6 etc. How do I make the numbers in the second .slideshow div reset and start from 1 again? This is really hard to explain concisely. I hope someone gets the gist.

  • Doubt about a particular pattern of Javascript class definition

    - by fenderplayer
    Recently i saw the following code that creates a class in javascript: var Model.Foo = function(){ // private stuff var a, b; // public properties this.attr1 = ''; this.attr2 = ''; if(Model.Foo._init === 'undefined'){ Model.Foo.prototype = { func1 : function(){ //...}, func2 : function(){ //... }, //other prototype functions } } Model.Foo._init = true; } // Instantiate and use the class as follows: var foo = new Model.Foo(); foo.func1(); I guess the _init variable is used to make sure we don't define the prototypes again. Also, i feel the code is more readable since i am placing everything in a function block (so in oop-speak, all attributes and methods are in one place). Do you see any issues with the code above? Any pitfalls of using this pattern if i need to create lots of classes in a big project?

  • jquery "this" binding issue on event handler

    - by clyfe
    In jquery an event hadler's binding is the event generating DOM element (this points to the dom element). In prototype to change the binding of an event handler one can use the bindAsEventListener function; How can I access both the instance and the DOM element from a event handler? Similar to http://stackoverflow.com/questions/117361/how-can-i-bind-an-event-handler-to-an-instance-in-jquery function Car(){ this.km = 0; $("#sprint").click(this.drive); //setup event handler } // event handler // in it I need to access both the clicked element // and the binding object (instance of car) Car.prototype.drive = function(){ this.km += 10; // i'd like to access the binding (but jq changes it) this.css({ left: this.km }); // also the element // NOTE that is inside this function I want to access them not elsewhere } var car = new Car();

  • Name lookup for names not dependent on template parameter in VC++2008 Express. Is it a bug?

    - by Maciej H
    While experimenting a bit with C++ templates I managed to produce this simple code, for which the output is different, than I expected according to my understanding of C++ rules. void bar(double d) { std::cout << "bar(double) function called" << std::endl; } template <typename T> void foo(T t) { bar(3); } void bar(int i) { std::cout << "bar(int) function called" << std::endl; } int main() { foo(3); return 0; } When I compile this code is VC++2008 Express function bar(int) gets called. That would be the behaviour I would expect if bar(3);in the template body was dependent on the template parameter. But it's not. The rule I found here says "The C++ standard prescribes that all names that are not dependent on template parameters are bound to their present definitions when parsing a template function or class". Am I wrong, that "present definition" of bar when parsing the template function foo is the definition of void bar(double d);? Why it's not the case if I am wrong. There are no forward declarations of bar in this compilation unit.

  • jQuery load to multiple divs

  • How can I use "IF statements" in a postgres trigger

    - by Dan B
    I have a trigger function that I only want to fire on certain instances of INSERTS, in this case, if do_backup = true. If it fires in all instances, I get an infinite loop. The logic seems pretty simple to me, and the rest of the function works. But the trigger function does not seem to register my conditional and always runs, even when backup = true. CREATE OR REPLACE FUNCTION table_styles_backup() RETURNS TRIGGER AS $table_styles_backup$ DECLARE ... do_backup boolean; BEGIN SELECT backup INTO do_backup FROM table_details WHERE id=NEW.table_meta_id; IF (do_backup = true) THEN ... INSERT INTO table_styles_versions ( ... ) VALUES ( ... ); END IF; RETURN NULL; END; $table_styles_backup$ LANGUAGE plpgsql; CREATE TRIGGER table_styles_backup AFTER INSERT ON table_styles FOR EACH ROW EXECUTE PROCEDURE table_styles_backup();

  • Why is `goog.Disposable.call(this);` necessary?

Doesn't Foo already inherit from Disposable with goog.inherits(foo, goog.Disposable);? goog.provide('foo'); /** * @constructor */ foo = function(){ goog.Disposable.call(this); } goog.inherits(foo, goog.Disposable); foo.prototype.doSomething = function(){ ... } foo.prototype.disposeInternal = function(){ ... }

  • Linux signals with extra information parameter

    - by Tester
    I was to have some extra information in the callback to sa_sigaction handler, it does not seems possible. So I was wondering if you could suggest me alternatives. Basic requirements: Function A raises an signal/event with a pointer to a struct Handler function tackles the event. The handler function would only be called on an event and a loop to wait for the event, as in select() , is undesirable. TIA

  • Processing data from an AJAX request

    - by Josh K
    I have a PHP API I'm working with that outputs everything as JSON. I need to call one of the API methods and parse it out using an AJAX request. I am using jQuery (though it shouldn't matter). When I make the request it errors out with a "parsererror" as the textStatus and a "Syntax Error: invalid label" when I make the request. Simplified code: $.ajax ({ type: "POST", url: "http://mydomain.com/api/get/userlist/"+mid, dataType: "json", dataFilter: function(data, type) { /* Here we assume and pray */ users = eval(data); alert(users[1].id); }, success: function(data, textStatus, XMLHttpRequest) { alert(data.length); // Should be an array, yet is undefined. }, error: function(XMLHttpRequest, textStatus, errorThrown) { alert(textStatus); alert(errorThrown); }, complete: function(XMLHttpRequest, textStatus) { alert("Done"); } }); If I leave off the eval(data) then everything works fine. Well, except for data still being undefined in success. Note that I'm taking an array of objects in PHP and then passing them out through json_encode. Would that make any difference? There has been no progress made on this. I'm willing to throw more code up if someone believes they can help. Here is the PHP side of things private function _get_user_colors($id) { $u = new User(); $u->get_where(array('id' => $id)); $bar = array(); $bar['user'] = $u->stored; foreach($user->colors as $color) { $bar['colors'][] = $color; } echo(json_encode($bar)); } I have had zero issues using this with other PHP based scripts. I don't know why Javascript would take issue with it.

  • Class Template Instantiation: any way round this circular reference?

    - by TimYorke34
    I have two classes that I'm using to represent some hardware: A Button and an InputPin class which represent a button that will change the value of an IC's input pin when it's pressed down. A simple example of them is: template <int pinNumber> class InputPin { static bool IsHigh() { return ( (*portAddress) & (1<<pinNumber) ); } }; template <typename InputPin> class Button { static bool IsPressed() { return !InputPin::IsHigh(); } }; This works beautifully and by using class templates, the condition below will compile as tightly as if I'd handwritten it in assembly (a single instruction). Button < InputPin<1> > powerButton; if (powerButton.IsPressed()) ........; However, I am extending it to deal with interrupts and have got a problem with circular references. Compared to the original InputPin, a new InputPinIRQ class has an extra static member function that will be called automatically by the hardware when the pin value changes. I'd like it to be able to notify the Button class of this, so that the Button class can then notify the main application that it has been pressed/released. I am currently doing this with function pointers to callbacks. In order for the callback code to be inlined by the compiler, I need to pass the function pointers as template parameters. So now, both of the new classes have an extra template parameter that is a pointer to a callback function. Unfortunately this gives me a circular reference because to instantiate a ButtonIRQ class I now have to do something like this: ButtonIRQ< InputPinIRQ< A1, ButtonIRQ<....>::OnPinChange, OnButtonChange > pB; where the <...... represents the circular reference. Does anyone know how I can avoid this circular reference? I am new to templates, so might be missing something really simple. It's important that the compiler knows exactly what code will be run when the interrupt occurs as it then does some very useful optimisation - it is able to inline the callback function and literally inserts the callback function's code at the exact address that is called on a h/w interrupt.

  • JavaScript Prototype and Encapsulation

    - by Adam Davies
    Sorry I'm probably being a realy noob here...but: I have the following javascript object: jeeni.TextField = (function(){ var tagId; privateMethod = function(){ console.log("IN: privateMethod"); } publicMethod = function(){ console.log("IN: publicMethod: " + this.tagId); } jeeni.TextField = function(id){ console.log("Constructor"); this.tagId = id; } jeeni.TextField.prototype = { constructor: jeeni.TextField, foo: publicMethod }; return jeeni.TextField; }()); Now when I run the following code I get the corresponding result: var textField1 = new jeeni.TextField(21); // Outputs: Constructor textField1.foo(); // Outputs: IN: publicMethod: 21 console.log(textField1.tagId); // Outputs: 21 console.log(textField1.privateMethod); // Outputs: undefined So my question is why is privateMethod hidden and tagId is not. I want them both to be private scope. Please help a noob. Thanks

  • Python, lambda, find minimum

    - by qba
    I have foreach function which calls specified function on every element which it contains. I want to get minimum from thise elements but I have no idea how to write lambda or function or even a class that would manage that. Thanks for every help. I use my foreach function like this: o.foreach( lambda i: i.call() ) or o.foreach( I.call ) I don't like to make a lists or other objects. I want to iterate trough it and find min. I manage to write a class that do the think but there should be some better solution than that: class Min: def __init__(self,i): self.i = i def get_min(self): return self.i def set_val(self,o): if o.val < self.i: self.i = o.val m = Min( xmin ) self.foreach( m.set_val ) xmin = m.get_min() Ok, so I suppose that my .foreach method is non-python idea. I should do my Class iterable because all your solutions are based on lists and then everything will become easier. In C# there would be no problem with lambda function like that, so I though that python is also that powerful.
