i have tried see if can @ least start getting somewhere on getting started. 

function myfunction() { // create new, plain <span> element var sp1 = document.createelement("div");  // reference element, before want insert element var sp2 = document.getelementbyid("commentinblog"); // reference parent element var parentdiv = sp2.parentnode;  // insert new element dom before sp2 parentdiv.insertbefore(sp1, sp2); }

but can't seem quite wrap head around how works. w3schools site helped me understand basic it's still difficult concept trying wrap head around. can me figure out how clone user inputted comments , text , update it. also, if can me understand better.

you mixing default javascript , jquery in code not work. try this:

function myfunction() {      var $newdiv = $('<div class="panel panel-default comment"><div class="panel-heading">' + $('#comment_name').val() + '</div><div class="panel-body">' + $('#comment').val() + '</div></div>');      // if want new comment on top of old ones, use line     $newdiv.prependto('#comment_list');      // if want new comment below old ones, use line     $newdiv.appendto('#comment_list');  }

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.
