javascript - fadeOut dynamically loaded div using jquery -

-

im writing small app, , im having problems deleting (as in fading out) dynamically loaded div using jquery.

the problem presents when add new content box, if reload page , content box gets rendered not dynamically (as in database query), deletes fine(as in fade out), when div added anew, cant out.

$result = '<div class="my-music-item">'. $app['twig']->render('soundcloud-player.twig', array(             'url'=>$mix->geturl(),             'player_type'=>'artwork',             'url'=>$mix->geturl(),             'color'=>'ff0948',             'height'=>'200',             'width'=>'200'         )) . '<p class="delete-mix-wrapper"><a class="delete-mix" data-mix-id="'.$mix->getid().'" data-post-to="'.$app['url_generator']->generate('delete-mix-post').'" href="javascript:;">delete</a></p>' . '</div>';          return new response(json_encode(array(             'html'=>$result,             'status'=>'true'         )));

thats code creates div dynamically.

yet when click delete, nothing happens.

here comes code handles post request through js.

$('a.delete-mix').on('click', function() {     var parent = $(this).closest('div.my-music-item');     $.post($(this).attr('data-post-to'), { mix_id: $(this).attr('data-mix-id') })     .done(function(data) {         parent.css('background-color', 'pink');         parent.fadeout('fast');     }); });

i have been reading lot, without luck! first code looked bit differently, didnt had 

.on('click', function() {

but rather was

.click(function() {

thanks in advance input!

@psl correct. common problem adding event handlers using jquery element not exist on page when js run, means event handler not bound element, , nothing happens.

if change line

$('a.delete-mix').on('click', function() { ... } )

to

$( document ).on( 'click', 'a.delete-mix', function() { ... } )

then shouldn't have trouble.

the second argument being passed on() method acts filter original selector bind event handler to. explain example provided in plain english, telling browser listen clicks everywhere on page, , check if clicked happens <a> element class of delete-mix. if did happen click on a.delete-mix, callback function run. if didn't, nothing happen.

this not best solution. adding global click handler document can cause problems. better solution replace document more specific, such container element wrapping dynamic boxes adding. without more code i'm not entirely sure selector should be.

for more information, should read jquery documentation on() method.

hope helps.

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.
