jquery background from image to color and back again -

-

I have an html page in which jquery is loaded. There is no CSS at this time.

The background image is set to: 

  & lt; Body background = "image1.gif" & gt;   
 I'm trying to convert it to a color (say black) and again by returning the image using onclick.  
 I have been able to set up Dives and all colors are used to change the color:  
  jQuery ('body'). CSS ('background color', 'black');   
 On any other page, but it does not work here because I want to color the image again and again.  
 Then, I can use CSS to change the background and change the square instead:    
 
 
 P> 
 HTML:  
  & lt; Body class = "image" & gt;   
 CSS:  
  body.image {background-image: url ('image.gif'); } Body.colour {background color: black; }   
 For more scripting:  
  $ ('body'). AddClass ('color'). RemoveClass ('image');   
 and back again:  
  $ ('body'). AddClass ('image'). RemoveClass ('color');

qt - switch/case statement in C++ with a QString type -

-
I want to use switch-case in my program but the compiler generates an error. How can I use the switch statement with QString ? The compiler gives me this error: The expression of the switch type 'QString' is invalid My code is as follows : boolStopWord (the word QString) {bool flag = false; Switch (word) {case "the": flag = true; break ; "On" case: flag = true; break ; Case "in": flag = true; break ; Case "your": flag = true; break ; Case "near": flag = true; break ; Case "all": flag = true; break ; Case "this": flag = true; break ; } Return flag; } How do I use the switch statement with a Caststring ? You can not use the switch statement in C ++ language with integral or enum types. You can formally enter the square type of object in the switch statement, but this means that the compiler will look for a user-defined conversion to convert it to an integral or enum type.

What is a Python equivalent for Ruby's define_method , which is the dynamic generation of class methods will allow? (As can be seen in Wikipedia) Functions are first-class objects in Python and assign them The properties of a class or an example can be a way of doing the same thing as a Wikipedia example: colors = {"black": "000", "red": "F00", "green": "0f0", "yellow": "ff0", "blue": "00f", "magenta": "fff", "cyan": "0ff", "white": " FFF "} Class MyStream (ARR): Pass for Name, Code in colors.iteritems (): def _in_colour ( W code = code): return '& lt; Span style = "color:% s" & gt;% s & lt; / Span & gt; ' % (Code, self) setter (histrive, "in_" + name, _in_ color)
