问题 I have created a plugin to convert an HTML select box into a custom drop down using DIV's. All works well, but i'd like to make it a little better. see my jsFiddle At the end of the plugin I have 2 methods, slideDownOptions & slideUpOptions, I would like to make these available outside of the plugin so other events can trigger the action. Im getting a little confused how to do this and more specifically how to call the methods from both within the plugin AND from outside of the plugin. Any

问题 I'd like to do something like this: public static function createDynamic(){ $mydynamicvar = 'module'; self::$mydynamicvar = $value; } and be able to access the property from within the class with $value = self::$module; 回答1: I don't know exactly why you would want to do this, but this works. You have to access the dynamic 'variables' like a function because there is no __getStatic() magic method in PHP yet. class myclass{ static $myvariablearray = array(); public static function createDynamic

问题 I'm starting learning JAXB, so my question can be very silly. Now I have classes and want generate XML Schema. Going after this instruction I get exception IllegalAnnotationExceptions ... does not have a no-arg default constructor. Yeah. My classes haven't default no-arg constructors. It's too easy.

问题 Scenario: When I photograph an object, I take multiple images, from several angles. Multiplied by the number of objects I "shoot", I can generate a large number of images. Problem: Camera generates images identified as, 'DSCN100001', 'DSCN100002", etc. Cryptic. I put together a script that will prompt for directory specification (Windows), as well as a "Prefix". The script reads the file's creation date and time, and rename the file accordingly. The prefix will be added to the front of the

Like when should I do NSString *aString = @"Hello"; of should it be: NSString *aString = [[NSString alloc] initWithString:@"Hello"]; But then its different when you're assigning a value to an NSString property isn't it? Can someone clear this up for me? Thanks!! 回答1: In general you should do the first, but they are mostly functionally the same. You can treat constant NSStrings just like normal NSString string objects, for instance: [@"Hello" length] will

问题 So I know how to use .wrap , .wrapInner and .wrapAll but I am wondering how to use the quick creation syntax introduced in jQuery 1.4 and the wrap function together. Basically I want to be able to use var targetUl = $(this), // would be populated by script maxWidth = 1400; // would be populated by script $('<div />', { 'id':'wrap', 'css': { 'width': maxWidth, 'overflow':'hidden' } }).wrapAround(targetUl); Kinda like the .appendTo method works but for wrapping stuff… Can this be done? Thanks.
