javascript - bootstrap collapse, jquery active -

-

hi have made collapsible accordion menu bootstrap javascript plugin, menu works great know if possible use jquery active class keep menu opened @ current position when loading new page menu. learning javascript , therefore not sure how go doing this.

this of html of menu:

     <div id="nav">                               <div id="accordion">                         <div class="heading">                <a class="accordion-toggle nav-main-item" data-toggle="collapse" data-parent="#accordion" href="#collapseone">about</a>              </div><!--ends heading-->               <div id="collapseone" class="collapse">                  <ul>                  <li><a class="nav-sub-item" href="about.html">me</a></li>                  <li><a class="nav-sub-item" href="articles.html">articles</a></li>             </ul>              </div><!--ends collapseone-->          </div>      </div>

"me" , "articles" open when clicking on "about", both of link new page. menu stay open when clicking on links.

adding in class on collapseone make accordion open default.

<div id="nav">     <div id="accordion">         <div class="heading"> <a id="about" class="accordion-toggle nav-main-item" data-toggle="collapse" data-parent="#accordion" href="#collapseone">about</a>          </div>         <!--ends heading-->         <div id="collapseone" class="collapse">             <ul>                 <li><a class="nav-sub-item" href="about.html">me</a>                  </li>                 <li><a class="nav-sub-item" href="articles.html">articles</a>                  </li>             </ul>         </div>         <!--ends collapseone-->     </div> </div>  <script>     $(function() {        $('#collapseone').addclass('in');      }); </script>

java - Copying object fields -

-
what best way of copying classes when need have 2 independent variables? have simple class: public class myclass { boolean = false; string b= "not empty"; } do need make method : assign(myclass data ) { a= data.a; b= data.b; } is there automatic method copy (duplicate) objects in java? do need make method : pretty close. instead of making method, should make constructor. such constructors called copy constructor , , create them this: myclass(myclass data) { = data.a; b = data.b; } and create copy of instance, use constructor this: myclass obj1 = new myclass(); myclass obj2 = new myclass(obj1); copy constructor can tedious : using copy constructor create deep-copy can tedious, when class has mutable fields. in case, assignment create copy of reference, , not object itself. have create copy of fields (if want deep copy). can go recursive. a better way create deep copy serialize , deserialize object. why not use clone()? ...

c++ - Clear the memory after returning a vector in a function -

-
i have function processes , stores lot of data in , returns results vector of class. amount of data stored in function tremendous , want clear storage memory of function after finished job. necessary (does function automatically clear memory) or should clear memory function? update: vector<customers> process(char* const *filename, vector<int> id) { vector<customers> list_of_customers; (perform actions) return list_of_customers; } variables defined locally within function automatically released @ end of function scope. destructors objects called, should free memory allocated objects (if objects coded correctly). example of such object std::vector . anything you've allocated new must have corresponding delete release storage. try avoid doing own allocation , use raii instead, i.e. containers or smart pointers.
