javascript - How to expand height of the container div whenever child divs are expanded -

-

In my HTML page I have some & lt; Div & gt; s, which is also my requirement if I click on that link, its original container size is & lt; Div & gt; should be expanded (simply spreads as an andarean).

This is what I have tried to do: 

  $ ('add-comment'). Height ($ ('div. Height () + $ (' div.stream-widgets-block-comment-box ') height ());}) ;   
 The above statement adds the height of  
 , but the problem is that unless the code is executed,  The altitude of 
 -1 ends. 1. Edit <1: This is JSFiddle Link - I've added a div to it, which is the height on the extension Uses the page (click on Add a comment to check extension  
 
 
 
  
 
 
  $ ('height. Click on 'stream-widgets-block-comment-box') (function () {var vHight = $ ('div.extra'). Height (); $ ('Div.extra'). CSS ('height' You can use .css () and var.

c++ - Redefined variable in the other module -

-
Why do we redefine the variable in other modules, so it is OK to add this module together? I have written two modules main.cpp and module.cpp as the following: // - main.cpp-- // # include & lt; Stdio.h & gt; Int main () {int i = 5; Printf ("I value is% d", i); } and // - module.cpp - // int i = 7; I am now compiling and adding g ++ as the following: g ++ -c main .cpp g ++ - c module. cao g ++ - o bin main.o module.o and it's okay. But I hope the compilation will be successful, while the linker will throw an exception like redefining varaible when I'm running .bin output then the value of i is 5 . UPD: I understand that if we use I as global variable module main.cpp that linker will throw an error. The main variable in the function is a local variable of i function. It is not visible and is present outside the function is. Consider the following example #include & lt; Iostream & gt; Int i = 3; Int main (...
