parameter-passing

I have this bit of code that works great: function displayVals() { var phonevals = $("#bphonesel").val(); $('#bphone').val(phonevals); } $("select").change(displayVals); displayVals(); I want to be able to reuse it for all the other select boxes I have on my site. So, I thought I'd use parameters to do it. However, I've so far been unable to get the syntax correct. Here's what I've got, but it doesn't work. Any help would be appreciated. function displayVals(inputfld, boundfld) { var nvenval = $(inputfld).val(); $(boundfld).val(nvenval); } $("select").change(displayVals()); displayVals('

I am new to CDI, tried to find solution for this question, but, couln't found any. Question is Suppose I have one class which is being injected(A) from, where some value(toPass) is getting injected, now I want to pass this same value(toPass) to class B, which is getting injected from class A. public class A { String toPass = "abcd"; // This value is not hardcoded @Inject private B b; } public class B { private String toPass; public B(String toPass) { toPass = toPass; } } Can anybody please help me in this? Note: we cannot initialize the toPass variable of B in the same way as we have

From ?match.call : match.call is most commonly used in two circumstances: […] To pass most of the call to another function […] After reading that, I expected I could use match.call when I want to pass all arguments of one function to another function without listing these arguments one by one. Example: outer1 passes arguments one by one, outer2 uses match.call . outer1 <- function(a, b, c) { inner1(a, b, c) } inner1 <- function(a, b, c) { return(a + b + c$first + c$second) } outer2 <- function(a, b, c) { mycall <- match.call() inner2(mycall) } inner2 <- function(call) { return(call$a + call$b

I'm fairly new to php and I am trying to figure how do I set an optional parameter after the first optional parameter? For example I have the following code: function testParam($fruit, $veg='pota',$test='default test'){ echo '<br>$fruit = '.$fruit; echo '<br>$veg = '.$veg; echo '<br>Test = '.$test; } If i make the following calls: echo 'with all parama'; testParam('apple','carrot','some string'); //we get: //with all parama //$fruit = apple //$veg = carrot //Test = some string echo '<hr> missing veg'; testParam('apple','','something'); //we get: //missing veg //$fruit = apple //$veg = //Test =

For my programming languages course, I'm trying to write some code snippets in languages that use pass by name or pass by value-result, preferably by default, but any language that even supports either of those would be fine. However, I haven't been able to find a single language that supports either of them. Does anyone know of a language that uses pass by value-result or pass by name? Preferably an imperative language. The wikipedia article on evaluation strategy suggests that call-by-value-result is supported by fortran. Call-by-name is supported by algol 68. I think C Macros are Pass-by

I'm a newbie in the JavaScript world, and I came up with this weird problem when i was attempting prototype chaining inheritence. I have 3 classes //class parent function parent(param_1){ this.param = param_1; this.getObjWithParam = function(val){ console.log("value in parent class "+val); console.log("Constructor parameter : "+this.param); }; }; //class child function child(param_1){ this.constructor(param_1); this.getObjWithParam = function(val){ console.log("value in child class "+val); val = Number(val)+1; child.prototype.getObjWithParam.call(this, [val]); }; }; child.prototype = new

In a GLSL shader, I want to create a function that looks a bit like this : void MyFunction(out float results[9]) { float value0 = 3.1546; float value1 = 42; // whatever value /* ... long, complicated code ... */ results[0] = value0; results[1] = value1; results[2] = value2; ... } Can such a function signature be used and compiled in GLSL ? If no, are there any alternatives ? Yes, this is legal GLSL code. That doesn't mean it will certainly compile, but it is legal code. That being said, it's probably better to just return the array (which you can also do), rather than pass it as an output

I have a function called "tryMe" and I'm calling it without the parenthesis not precisely this but the idea is like what you would do here: setTimeout(tryMe,200); how can I pass parameters that I need? I am using a jquery plugin that enables me to call a function but I have to call it withou the parenthesis or it executes itself upon loading. setTimeout(function() { tryMe(parm1, parm2); }, 200); A more robust offering, to ensure that the values of parm1 , parm2 don't change before the timeout fires (per @lincolnk's comment): setTimeout(function() { var p1 = parm1; var p2 = parm2; tryMe(p1, p2)

The structure of my project is as follow: Proj Proj.pro --subProj --subProj.pro ----subsubProj ----subsubProj.pro Is there a way i can instance a global variable in subProj.pro and call it en e.g. subsubProj.pro like: Proj.pro: GLOBAL_VAR = true subsubProj.pro: message($$GLOBAL_VAR) Update Maybe I should more precise with my problem. The usual behavior in Qt Creator when you right-click on Proj and choose "Build project"Proj"" is that qmake Proj.pro gets invoked then qmake subProj.pro and then subsubProj.pro What I want to achieve is: When i build the project "Proj" only Proj.pro and subProj
