Object required error in javascript even when calling the function correctly
change <asp:TextBox ID="fromtxtbox" runat="server"></asp:TextBox> to: <asp:TextBox ID="fromtxtbox" ClientIDMode="Static" runat="server"></asp:TextBox> If you look at the source of the page you will see that the Id property of the span control is not "fromtxtbox"

Using the same instance of an object as the argument and as the calling object in calling a function
This will not be a problem functionally, but logically if the function must take an object as an argument, you should make this function static. In addition, since you are not modifying the incoming object, you should make the argument const. Finally, since copying the object may be more expensive than copying a reference, you may want to change the argument to be passed by reference. static void Complex::magnitude(const Complex &c); ... Complex myComplex(...); Complex::magnitude(myComplex);

calling function should return default value, if object (or any function result) is null
Not really, any code you would write this way would look horrible and/or use very slow reflection. Unless you use an actual Java preprocessor that can understand and change the code you've written. A better (but associated with quite a bit of refactoring) approach would be to make sure that the values in question cannot possibly be null. For example, you could modify the individual accessors (getSubObject(), getDesiredValue()) to never return null in the first place: make them return default values. The accessors on the default values return default values in turn.

JavaScript: why use prototype to call a function instead of just calling the function?
The key benefits are realized when "arr" is not an array, but something like an array; specifically, something with a "length" property and numerically-keyed properties. Good examples are the arguments object and NodeList objects from a DOM. Those things won't have a "slice" method, but they do have numerically-keyed properties and a "length" property. The trick works because the "slice" method is pretty forgiving. If you see it being used with something that's definitely an array already, then you're looking at code written by a confused person :) Oh, and note also that a short-cut is: var foo = [].slice.call(arguments, 0); You don't have to go to the prototype directly if you don't want to; you can get at it from an array instance just as easily. (Yes, it costs a dummy allocation,

Calling a function as a function in javascript/jQuery
If I understood everything correct: function bodyOnClick( e, optionalId ) { var nodeRef = optionalId ? document.getElementById( optionalId ) : this; if( typeof e === 'object' ) e.preventDefault(); var self = $(this); var id = nodeRef.data("id"); var url = $("#manufacturers_table").data("infourl"); var data_array = { id : id }; ajaxCall(url, data_array, "rhs_info"); } // --- $('body').on("click", ".manufacturer_details_link", bodyOnClick ); // --- bodyOnClick( 'someNodeID' ); But actually, calling bodyOnClick plain doesn't make much sense, since this would not reference any HTMLElement. So it only makes sense if you re-use the method on other event handlers, or explicitly call it like bodyOnClick.call( someNodeReference );

using std::transform for calling object's function
std::transform is fine for this: std::vector<std::string> string_vec; const int magic_number = 42; std::transform(std::begin(vec), std::end(vec), std::back_inserter(string_vec), [magic_number](std::shared_ptr<A> a){ return a->foo(magic_number); } ); Obviously, you need to figure out which int you want to pass to A::foo(int). In C++03, you can replace the lambda by a functor or function: struct get_foo { get_foo(int n) : n_(n) {} bool operator() (std::shared_ptr<A> a) const { return a->foo(n); } private: int n_; }; const int magic_number = 42; std::vector<std::string> string_vec; std::transform(std::begin(vec), std::end(vec), std::back_inserter(string_vec), get_foo(m

Calling function in C++ without creating an object
The call should be Controller::AlbumOps::SayHey(); // ^^ // double-colon You should put static on the in-class function declaration, not the out-of-class function definition (where it means something completely different, "internal linkage"). That is: in the header (AlbumOps.hpp): // ... namespace Controller { class AlbumOps { public: // ... static void SayHey(); // Note: 'static' here }; } // ... and in the implementation file (AlbumOps.cpp): either: // ... void Controller::AlbumOps::SayHey() // Note: no 'static' { cout << "Hey "; } // ... or: // ... namespace Controller { // ... void AlbumOps::SayHey() // Note: no 'static', no repeated 'Controller::' { cout <&

calling a function again in javascript
You haven't set any case for when no = 1. You have a case for when no != 1 and when no%2 != 0 both of which are false when no = 1. There isn't any increment logic in here to find the next number and return it. I think you are missing a } at the end of the no%2==0 clause. Also I fail to see why you have two identical buttons here, next and submit do the same thing. Moreover I would advice more descriptive IDs. div1 isn't a good name for a div.

calling function in a loop in javascript
The function is being executed 3 times just like you requested, the problem is that both delay and fadeIn use timers: they set a timer in the future when the function will be executed and return immediately: they are non-blocking calls. So, in your case, because you're calling the function 3 times at, let's say, 0.0001s, 0.0002s, and 0.0003s, the three kick in at, let's say, 5.0001, 5.0002 and 5.0003. What you had in mind were blocking calls to these functions. You expected the whole execution to stop until the animations were finished. This would stop the whole browser Javascript engine for the duration, meaning no other animation or user javascript interaction would be possible. To solve it, you have to use callbacks. You can supply a function to fadeIn that will be called once the ani

calling another frame ASP.NET C# function with javascript
That's not C#. It's Javascript. I doubt that the problem is with Mono, I suspect the problem is with the browser. Since the iframe is created by Ext.Net you have to reference it with the name Ext.Net gives to it. To get the name just use the developer tools of the browser, but it should be pnlAjax_IFrame. Or, if it's the only iframe in the parent page you'd better reference it by id: frmAjax = parent.frames[0].LoadVehStore2();

Run Javascript function before calling Servlet
What you need is just form validation with Javascript. First you need to include a call to a Javascript validation function into the onsubmit attribute of your form. Something like: <form name="myForm" action="YourServlet" onsubmit="return validateForm()"> ... </form> Then, if you're really familiar with Javascript, your validation function should be easy to create... Basically it's something like: function validateForm() { //Check form fields: //If they're are correct return true, //otherwise return false... } If the validation function validateForm() returns false, the form won't never be submitted, that's to say, the servlet won't be called... Note: usually you will have a validation function that actually calls other functions to check different parameter

Calling javascript function from Jquery
You need to load the script1.js file before the mywidget.js file (ie. place one before the other in the HTML). From there you should be able to call myFunction with no problems. If after this you're still having issues, you can use $.fn.myFunction() to extend jQuery's prototype. In essence by doing this you'll be adding functionality to jQuery.

Trouble with calling javascript function within another using D3
What's happening is that, in jsfiddle, the default is to encapsulate everything in a function that runs on window load. The code looks like this: window.onload=function(){your stuff} When you try to set the onload, the code structure is then structured like this: function firstFunction(){ function secondFunction(){ do stuff } } onload = secondFunction; The issue is that secondFunction is not accessible outside the scope of firstFunction. This is called variable scoping, and coding would suck without it. The way to solve this issue is to move your onload assignment to the javascript block. I'd recommend the built in d3 way of doing this: d3.select('button').on('click',newScatter); here I'm selecting the button and adding a click event handler. This works because there

What problem are you trying to solve?

How to write an R function which assigns to the object of the calling environment?
With the caveat that this is generally frowned upon, you can use the following: From the target environment, set a variable to the environment and then pass that as an argument to your function which you can use in assign, get etc en <- environment() myfunc <- function(..., en=en) { . etc . assign("varname", envir=en) } Note that if you are simply changing attributes, the setattr function of the data.table package already implements this quote nicely: setattr(x,name,value)

Calling a C# library function with out parameters in javascript
Out parameters used in this fashion is not a good idea. If you call a method you would expect it to do its job, if it can't it should throw, however if you really need that bool then you can wrap your output into a class and return that. In this case you can use an anonymous type if your using dot net 4.0 or later. public class Test { public object doSomething(string txt) { ... return new { text = "some return value", success = true }; } } var result = testInstance.doSomething("instr"); // result.text // result.success

JavaScript: self-calling function returns a closure. What is it for?
Declaring the variable outside the function makes the function use the same object every time. An example (with an integer instead of an object, for simplicity's sake): var c = { theMethod: function () { var m1 = 0; return function (theParameter) { m1++; console.log( m1 ); } }() }; c.theMethod(); c.theMethod(); // output: 1 2 var d = { theMethod: function () { return function (theParameter) { var m1 = 0; m1++; console.log( m1 ); } }() }; d.theMethod(); d.theMethod(); // output: 1 1 The self-invoking function works like this: var c = { theMethod: function () { var m1 = 0; return function (theParameter) { m1++; console.l

Objective-C method/function calling. (from javascript example)
this is not a full translation as there are some pieces of your code that seem to be missing (see my comment above).. but this will at least give you a starting point: var doSomething = function (callback) { //some work } in obj-c this is more or less the same as a block so you can write something like this: void (^doSomething)(id) = ^(callback) { // some work } I won't explain the syntax, that's what the link above is for. Since javascript is loosely typed, and you haven't specified what datatype callback is.. i set the callback parameter as a generic id in obj-c, which can stand for any class (including a block) var start = function (interval, other, cb) { setInterval(doSomething(function(result){ total = result + other cb(total) }), interval) } here you are b
