local

I can imagine 3 type of visibility for variables (but I think there are more): Variable is used within a method and any changes of the value of this variable are not visible from outside of the method (so it is local for a particular method). A variable is local to the class meaning that it is unvisible from outisde of the class. However, any method of the class can easily see and change value of this variable without necessity to give the variable in the list of arguments of methods (so it is kind of global within the class). Variable can be accessed by "objectName.variableName". How do I

I am trying to save selected option in localStorage in HTML, so if you refresh page, the selection stays selected. I have try this: HTML: <select id="edit"> <option>1</option> <option>2</option> <option>3</option> </select> jQuery: $(function() { $('#edit').change(function() { localStorage.setItem('todoData', this.innerHTML); }); if(localStorage.getItem('todoData')){ localStorage.getItem('todoData'); } }); But this seems not to work, any ideas, realy thanks for help... Live Demo here: http://jsfiddle.net/nwk1g6vp/ Store and set the value, not the entire HTML of the select $(function() { $('

This was asked as a comment in Cython - copy constructors . The following code doesn't compile in Cython: def bar(int i): if i == 0: return i else: cdef int j j = i+1 return j whereas this one is perfectly correct: def foo(int i): cdef int j if i == 0: return i else: j = i+1 return j The question is: why does Cython forces to declare j at the beginning of the function and not in the else block ? The reason is scoping rule in Python vs C/C++. Cython is trying to get the better of both Python and C/C++ world. But there are some incompatibilities between those two worlds. Scoping rule is one.

I've googled this extensively to no avail. I cannot seem to wrap my head around this concept. Why are static final fields accepted in local classes? Such as the following example below: public void sayGoodbyeInEnglish() { class EnglishGoodbye { public static final String farewell = "Bye bye"; public void sayGoodbye() { System.out.println(farewell); } } System.out.println(EnglishGoodbye.farewell); EnglishGoodbye myEnglishGoodbye = new EnglishGoodbye(); myEnglishGoodbye.sayGoodbye(); } In class EnglishGoodbye the variable farewell is allowed? Why? I'm confused. Why is that allowed but no static

For some reason this jQuery code I have in my site will work on jsFiddle but not locally. The code is the same. I have just copied and pasted it. Can anyone explain to me what is going on? jsFiddle Local Using Chrome's developer tools, you get an error in the console: Uncaught SyntaxError: Unexpected token ILLEGAL Taking a look at the code, you see: $(document).ready(function() { $('#workclick').click(function() { $("#header").height($("#headwrapper").height()); }); $('#workclick').click(); $('#aboutclick, #contactclick, #introclick').click(function() { $("#header").height('0'); });​ // here

This is a simple question. I know global variables are created when they are declared outside a function (says w3schools.com). My question is, if I create a global variable and edit it in a function, does it become local? Does the new value given by the function become the global value? In general, no, editing a global does not make it local: var myglob = 5; function incGlob() { myglob = myglob + 1; } incGlob(); console.log(myglob); // is 6 now However, if you pass the global variable as an argument, the argument is a local copy: var myglob = 5; function incArg(myloc) { myloc = myloc + 1; }

I need to ship a collection of Python programs that use multiple packages stored in a local Library directory: the goal is to avoid having users install packages before using my programs (the packages are shipped in the Library directory). What is the best way of importing the packages contained in Library ? I tried three methods, but none of them appears perfect: is there a simpler and robust method? or is one of these methods the best one can do? In the first method, the Library folder is simply added to the library path: import sys import os sys.path.insert(0, os.path.join(os.path.dirname(_

e.g. x = 123 p = Proc.new { x = 'I do not want change the value of the outer x, I want to create a local x' } In Ruby Is there something the same as "my" keyword in Perl ? As per the Perl documentation of my ,I think you are looking for something like below in Ruby:- x = 123 p = Proc.new {|;x| x = 'I do not want change the value of the outer x, I want to create a local x' } p.call # => "I do not want change the value of the outer x, I want to create a local x" x # => 123 ChrisPhoenix Beware!
