jQuery selector -


How can I select and add a square to the previous and next tags. 

  & lt; Div class = "sub" & gt; & Lt; Ul & gt; & Lt; Li & gt; & Lt; A href = "#" & gt; A & lt; / A & gt; & Lt; Ul & gt; & Lt; Li & gt; & Lt; A href = "#" & gt; B & lt; / A & gt; & Lt; Ul & gt; & Lt; Li & gt; & Lt; A href = "#" & gt; C & lt; / A & gt; & Lt; / Li & gt; & Lt; Li & gt; & Lt; A href = "#" & gt; D & lt; / A & gt; & Lt; / Li & gt; & Lt; Li & gt; & Lt; A href = "#" & gt; E & lt; / A & gt; & Lt; / Li & gt; & Lt; / Ul & gt; & Lt; / Li & gt; & Lt; Li & gt; & Lt; A href = "#" & gt; F & lt; / A & gt; & Lt; / Li & gt; & Lt; Li & gt; & Lt; A href = "#" & gt; G & lt; / A & gt; & Lt; / Li & gt; & Lt; / Ul & gt; & Lt; / Li & gt; & Lt; Li & gt; & Lt; A href = "#" & gt; H & lt; / A & gt; & Lt; / Li & gt; & Lt; Li & gt; & Lt; A href = "#" & gt; I & lt; / A & gt; & Lt; / Li & gt; & Lt; Li & gt; & Lt; A href = "#" & gt; Jammu & lt; / A & gt; & Lt; / Li & gt; & Lt; / Ul & gt; & Lt; / Div & gt; Example: Now I want to add 2 css classes (.preview and nxt), such as element elements that accept the mouse   li & gt; ; A href = "#" & gt; G & lt; / A & gt; & Lt; / Li & gt; , so I have 2 squares to  & lt; Li & gt; & Lt; A href = "#" & gt; I want to add to  and  & lt; Li & gt; & Lt; A href = "#" & gt; H & lt; / A & gt; & Lt; / Li & gt;  
   
 snipp: 
 
  $ (document) .ready (function () {$ ('li'). CSS ({'Border-top': '1px solid green', 'border (' 1px solid green '')); $ ('lia') each (function (intindex) {$ (this). Mouse over (function $ (This) .css ({'border-top': '1px solid red', 'border bottom': '1px solid red'}); $ (this) .prev () Find ('li' CSS ({'border-bottom': 'none'}); $ (this) .next (). ('Li'). CSS ({'border-top': 'none'})}}. MouseOut (function {$ (this) .css ({'border-top': '1 px solid green', 'border bottom': '1 px solid green'});});});});  
 
 thanks In advance,

Try it out: 

  var $ a = $ ( '. Sub li & gt; a'); $ A.mouseenter (function () {var index = $ a.index (this); var prev = (index - 1> = 0)? $ A.eq ( Index - 1) .addClass ('prev'): $ next ($); var next = $ a.eq (index + 1) .addClass ('next'); $ a.not (prev) .No (forward) .removeClass ('Prev next');});

Edit: A minor improvement. First, if you were on the first item, then the .prev category will be added to the last item in the list. This has been done right.

Edit: Here is a version that uses the user's .each () . It's a bit more efficient to do this in this way because it eliminates the need to call $ a.index (this); for each mousecenter

Try it: 

  var $ a = $ ('. Sub li & gt; a '); $ A.each (function (index) {$ .mouseenter (function () {var prev = (index - 1> = 0)? $ A.eq (index -1) .addClass ('prev'): $ (); Var next = $ a.eq (index + 1) .addClass ('next'); $ a.not (prev) .No (forward) .removeClass ('prev next');})}} ; Edit   Edit:  If you are having any issues with the continuous deletion of the appropriate class, get rid of this line of code:  < Pre>  $ a.not (prev). No (forward) .removeClass ('prev next'); Change it to

and handler on : 

  $ a.removeClass ('Previous Next');

or: 

  $ a.filter ('., Prev, .next'). RemoveClass ('Previous Next');

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....
