user-defined

I am trying to call a user defined function in jQuery: $(document).ready(function() { $('#btnSun').click(function() { myFunction(); }); $.fn.myFunction = function() { alert('hi'); } }); <script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script> <button id="btnSun">Say hello!</button> I tried the following as well: $(document).ready(function() { $('#btnSun').click(function() { myFunction(); }); }); function myFunction() { alert('hi'); } <script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script> <button id="btnSun">Say hello!</button>

Is there a way to list all the user-defined variables & function in a Notebook ? I would like this for the comfort it brings to a notebook overview as well as to spot potential multiple use of a variable name (thus redefining it accidental) To find names in a context, say in the Global context, try Names["Global`*"] --Nasser 来源： https://stackoverflow.com/questions/6166027/list-all-user-defined-variables-functions-in-a-notebook-in-mathematica

Since Python does not provide left/right versions of its comparison operators, how does it decide which function to call? class A(object): def __eq__(self, other): print "A __eq__ called" return self.value == other class B(object): def __eq__(self, other): print "B __eq__ called" return self.value == other >>> a = A() >>> a.value = 3 >>> b = B() >>> b.value = 4 >>> a == b "A __eq__ called" "B __eq__ called" False This seems to call both __eq__ functions. Just looking for the official decision tree. The a == b expression invokes A.__eq__ , since it exists. Its code includes self.value == other
