  • How to import php with javascript?

    - by dcp3450
    I know JavaScript is client side and PHP is server-side. I also know this is an odd question. However, the CMS editor I'm using will not allow php to be stored to the database (it's the same editor used by Dupral). I can store JavaScript though. Can I import a php file with JavaScript. Or rather read the php file, store the content in a variable then out put the content to the screen?

  • String literals in python

    - by kjakeb
    Hello, Is there a way to declare a string variable in python such that everything inside of it is automatically escaped, or has its literal character value? I'm NOT asking how to escape the quotes with slashes, that's obvious. What I'm asking for is a general purpose way for making EVERYTHING in a string literal so that I don't have to manually go through and escape everything for very large strings. Anyone know of a solution? Thanks!

  • Exact cin equivalent function in python

    - by gkt.pro
    Suppose user enter this string at terminal 123 456 456 //then hit enter How do I scan these three (could be more) numbers in different variables in python Could be something like this: for i in range(1,n) m[i]=#WHAT FUNCTION SHOULD I PUT HERE In c++ we can easily use cin>>m[i] inside above loop to scan the variables. If i use input() or raw_input() , they would scan whole line in single variable.

  • Is there a better way to declare an empty, typed matrix in MATLAB?

    - by Arthur Ward
    Is there a way to "declare" a variable with a particular user-defined type in MATLAB? zeros() only works for built-in numeric types. The only solution I've come up with involves using repmat() to duplicate a dummy object zero times: arr = repmat(myClass(), [1 0]) Without declaring variables this way, any code which does "arr(end+1) = myClass()" has to include a special case for the default empty matrix which is of type double. Have I missed something a little more sensible?

  • Quick question about jQuery selector content efficiency

    - by serg
    I am loading HTML page through ajax and then doing a bunch of searches using selectors: $.ajax({ ... dataType: "html", success: function(html) { $("#id1", html); $(".class", html); //... } } Should I extract $(html) into a variable and use it as a content, or it doesn't matter (from performance point)? success: function(html) { $html = $(html); $("#id1", $html); $(".class", $html); //... }

  • extract variables from an expression using javascript regexp

    - by powerboy
    For example, here is a string representing an expression: var str = 'total = sum(price * qty) * 1.09875'; I want to extract variables (i.e., 'total', 'price' and 'qty' but not 'sum' since 'sum' is a function name) from this expression. What is the regexp pattern in javascript? Variable name consists of letters, digits, or the underscore, beginning with letters or the underscore.

  • iPhone memory management (with specific examples/questions)

    - by donkim
    Hey all. I know this question's been asked but I still don't have a clear picture of memory management in Objective-C. I feel like I have a pretty good grasp of it, but I'd still like some correct answers for the following code. I have a series of examples that I'd love for someone(s) to clarify. Setting a value for an instance variable. Say I have an NSMutableArray variable. In my class, when I initialize it, do I need to call a retain on it? Do I do fooArray = [[[NSMutableArray alloc] init] retain]; or fooArray = [[NSMutableArray alloc] init]; Does doing [[NSMutableArray alloc] init] already set the retain count to 1, so I wouldn't need to call retain on it? On the other hand, if I called a method that I know returns an autoreleased object, I would for sure have to call retain on it, right? Like so: fooString = [[NSString stringWithFormat:@"%d items", someInt] retain]; Properties. I ask about the retain because I'm a bit confused about how @property's automatic setter works. If I had set fooArray to be a @property with retain set, Objective-C will automatically create the following setter, right? - (void)setFooArray:(NSMutableArray *)anArray { [fooArray release]; fooArray = [anArray retain]; } So, if I had code like this: self.fooArray = [[NSMutableArray alloc] init]; (which I believe is valid code), Objective-C creates a setter method that calls retain on the value assigned to fooArray. In this case, will the retain count actually be 2? Correct way of setting a value of a property. I know there are questions on this and (possibly) debates, but which is the right way to set a @property? This? self.fooArray = [[NSMutableArray alloc] init]; Or this? NSMutableArray *anArray = [[NSMutableArray alloc] init]; self.fooArray = anArray; [anArray release]; I'd love to get some clarification on these examples. Thanks!

  • c++ volatile multithreading variables

    - by anon
    I'm writing a C++ app. I have a class variable that more than one thread is writing to. In C++, anything that can be modified without the compiler "realizing" that it's being changed needs to be marked volatile right? So if my code is multi threaded, and one thread may write to a var while another reads from it, do I need to mark the var volaltile? [I don't have a race condition since I'm relying on writes to ints being atomic] Thanks!

  • Tracing memory leaks

    - by iFloh
    My favorite candidate again. I am in the process of identifying memory leaks in my app (a puzzling challenge for a newbe like me). I am using the xCode leak analyzer, but what puzzles me is how to trace back a memory leak to its variable or value. Is there a pointer to the instances that have reserved a memory address where a leak is identifyed? How do I best go about it?

    - by MarcoB
    Using python and wsgiref.handlers, I can get a single variable from a form with self.handler.request.get(var_name), but how do I iterate through all form variables, be they from GET and POST? Is it something like this? for field in self.handler.request.fields: value = self.handler.request.get(field) Again, it should include both fields included in the POST and fields from the query string, as in a GET request.

  • Selecting all elements

    - by Eelke
    This should be really simple but I'm a javascript/jQuery rookie, so here we go: With the following code I can select a certain element var user = $(".ui-selected .user-name").html(); But if there are multiple elements with the above classes, only the first value gets selected. What I would like to accomplish is a variable with all the elements seperated by a , like: user1,user2,user3 ... etc. Any help would be greatly appreciated, thanks in advance!
