  • const_get but for variables

    - by aharon
    So I know you can say Kernel.const_get("ClassName") and you'll get back the class to which the string corresponds in name. But what about for variables? Is there a way to do: test = "heyas" some_method_here("test") #=> "heyas" Thanks so much

  • define method for instance of class

    - by aharon
    Let there be class Example defined as: class Example def initialize(test='hey') self.class.send(:define_method, :say_hello, lambda { test }) end end On calling Example.new; Example.new I get a warning: method redefined; discarding old say_hello. This, I conclude, must be because it defines a method in the actual class (which makes sense, from the syntax). And that, of course, would prove disastrous should there be multiple instances of Example with different values in their methods. Is there a way to create methods just for the instance of a class from inside that instance? Thanks so much.

  • stick element to top of page until next element of that type appears

    - by aharon
    I'm having a hard time giving a good description of this, but bear with me: If I have a page structed like this <h2>Chapter 1</h2> <p>Lots of text that has mutiple screen worths of content</p> <h2>Chapter 2</h2> <p>Lots of text...</p> I'd like to have "Chapter 1" absolutely positioned or whatever at the top of the page until the user scrolls down to where "Chapter 2" starts, at which point now "Chapter 2" is displayed at the top of the page. We can add wrapper classes and divs if needed. Solutions that use JQuery would be great.
