php - JQuery removing and adding classes -


I am trying to use JQuery to add / remove classes as part of a function that is main

Here is my javascript: 

  $ (document) .ready (function () {var clickHandler = function ( $ ('. (' 'Selected'). $ ('Selected'); $ (this) .addClass ('selected' '($.' 1 '), clickhandler); $ (' link2 ' ). Bind ('click', {id: '2'}, clickhandler); $ ('link3'). I have divs HTML (this part works):   
  
 
  & lt; div id = "options_1" class = "tab" & gt; & lt; h3 & gt; your feed & lt; / h3 & gt; & lt;? = $ UserFeed? & Gt  
  All recent activity  $ Feed? & Gt; & lt; / div & gt; & lt; div id = "options_3" class = "tab" & gt; & lt; h3 & gt; Trends & lt; / H3 & gt; coming soon! & Lt; / Div & gt;  
 
 And here's the HTML of the link in the sidebar section of the page that controls the div switching. The "selected" category should be removed from Option 1 and added to all the user selected links, but this is not happening. The square is not being changed at all. 
 
  & lt; Ul id = "feedOptions" & gt; & Lt; Li & gt; & Lt; A href = "#" id = "1" class = "link 1" class = "selected" & gt; Your feed & lt; / A & gt; & Lt; / Li & gt; & Lt; Li & gt; & Lt; A href = "#" id = "2" square = "link 2" & gt; All activity & lt; / A & gt; & Lt; / Li & gt; & Lt; Li & gt; & Lt; A href = "#" id = "3" square = "link 3" & gt; Trends & lt; / A & gt; & Lt; / Li & gt; & Lt; / Ul & gt;  
 
 As I said above, I can not change the 'selected' square at all. Any suggestions?

You have multiple classes attributes on the same element, rather than its: 

  & lt; A href = "#" id = "1" class = "link1" class = "selected" & gt; Your feed & lt; / A & gt;

You should have it (a feature, different classes with location): 

  & lt; A href = "#" id = "1" class = "link 1 selected" & gt; Your feed & lt; / A & gt;

Eclipse CDT variable colors in editor -

I hope this is a good question to ask here. This programming is related, so I thought it would be better than the superuser, so I am using the CDT C ++ Eclipse plugin. I know how the editor changes colors for some things But is there a way to do that all the variables are different colors? For example in KDEValue, it sets the local variables and square variables in different colors and bold square squares. Can I copy it to CDT? Eclips provides some level of color customization for text editor syntax You can see it on the following: There are many elements, including the Window> Preferences> C / C ++> Editor> Syntax color code that can be changed, assembly, Comments, Preprocessor and Doxian Under the code, it is possible to change the color of some variable types, such as global variables, local variable announcements, local variable references, and parameter variables. But I do not think the code is capable of changing the color of each variable declared....
