jQuery pass more parameters into callback

Or, more simply using ES6 Arrow Functions:

As for your specific example, I haven't used t...
How does origin/HEAD get set?
... HEAD branch (remote HEAD is ambiguous, may be one of the following):
foo
master
Oddly, although the notion of HEAD printed this way will change if things change on the remote (e.g. if foo is removed), it doesn't actually update refs/remotes/origin/HEAD. This can lead to really odd situat...

Why is Class.newInstance() “evil”?
... this very simple class (does not matter that it is broken):
static class Foo {
public Foo() throws IOException {
throw new IOException();
}
}
And you try to create an instance of it via reflection. First Class::newInstance:
Class<Foo> clazz = ...

Why does flowing off the end of a non-void function without returning a value not produce a compiler
... as a curiosity, look what this code does:
#include <iostream>
int foo() {
int a = 5;
int b = a + 1;
}
int main() { std::cout << foo() << std::endl; } // may print 6
This code has formally undefined behaviour, and in practice it's calling convention and architecture depe...
How to flush output of print function?
...ust provide flush=True as a keyword argument to the print function:

What would be C++ limitations compared C language? [closed]
...itrary subset of C++. C is not a subset of C++ at all.
This is valid C:
foo_t* foo = malloc ( sizeof(foo_t) );
To make it compile as C++ you have to write:
foo_t* foo = static_cast<foo_t*>( malloc ( sizeof(foo_t) ) );
which isn't valid C any more. (you could use the C-style cast, it wh...
