Jquery ajax search debounce -

-

i building live search website return results based on user types. want request sent when user has finished typing.

i have tried few implementations using timers , debounce method underscore.js seem getting similar result.

while typing, request delayed until have finished typing. seems fire inputs if queued. example, if type in "bikes" results come like:

b  bi  bik  bikes

as such, stream of results search.

this current implementation using underscore js

$('#search_term').on('keyup', _.debounce(function (e) {         $.ajax({             type: "get",              url: "quicksearch.php",             data: { search_term:$('#search_term').val()},             success: function(msg){               $('#quick_search_results').html(msg).slidedown();             }     });  }, 100));

anyone have ideas?

maybe users cannot type fast enough. set wait parameter of _.debounce function longer 100ms in example: (see specs: _.debounce(function, wait, [immediate]). 

$('#search_term').on('keyup', _.debounce(function (e) {    $.ajax({         type: "get",         url: "quicksearch.php",         data: { search_term:$('#search_term').val()},         success: function(msg){$('#quick_search_results').html(msg).slidedown();}    }); }, 300)); // < try 300 rather 100

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.
