make onmouseenter and onmouseleave to work in chrome - html, javascript, jquery -

- 

<div style="position: relative; left: 50px; top: 30px; width: 300px; height: 150px; background: #222222;" onmouseenter="this.style.background='#aaaaaa'" onmouseleave="this.style.background='#222222';"></div>

http://jsfiddle.net/z8kue/1/

onmouseenter , onmouseleave events works in firefox , opera, apparently doesn't work @ in chrome...

how can simple basic div in fiddle become functional in chrome, without changing it's content (beside assigning class)?

the ideal solution, if possible, somehow register onmouseenter , onmouseleave events chrome users, without assigning class.

edit: know onmouseover , onmouseout, out of question - need workaround code have practical reasons.

edit 2: right have jquery specific class - http://jsfiddle.net/z8kue/6/. have lot of divs it's events written in html, inside of <div></div>

so example, have 2 divs these (http://jsfiddle.net/z8kue/8/). imagine there 200 divs instead , lot more variety in events. how can handled work in chrome jquery in practical way? (definitely not erasing content 200 divs , writing jquery 200 or more lines)

working demo

you jquery

code

$('div').mouseenter(function () {     $(this).css('background', '#aaaaaa'); }); $('div').mouseleave(function () {     $(this).css('background','#222222'); });

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.
