javascript - Event on one element to trigger event on another -

-

i'll use specific example apply any event on 1 element triggering any event on another. suppose want focus <input> when click <span>. can using directive like:

<div ng-controller="ctrl">     <span ng-focus-other>focus</span><input> <div>  app.directive("ngfocusother", function () {     return function (scope, element) {         element.bind("click", function () {             this.nextsibling.focus();         });     }; });

however not seem angular. not work there changes dom (e.g. if <input> moved before <span>). nice if same code work on multiple groups of <span>-<input> combinations perhaps each different dom layout.

what angular way of using 1 event trigger event on element?

why not have clicking span set boolean called "inputfocused" true , let input pay attention scope variable. i.e.

<span ng-click="inputfocused = true">focus</span> <input ng-focus="inputfocused" value="give me focus">

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.

erlang - Saving a digraph to mnesia is hindered because of its side-effects -

-
updated the digraph library in erlang implements data type side-effectful. each operation on data type saves new state in ets table -- instead of returning altered version of itself, more common in functional languages. the problem usage perspective, impedes effort store or pass around state in convenient way requiring me first "collect" state before can start juggle around. the closest solution have seen far serializer/deserializer , these have drawback tied current structure of digraphs instead of operating on abstract type -- prevents future proof solution. update pascal pointed out serializer utilizes interface of digraph, , hence eliminates drawback mentioned above. better, albeit still inconvenient, see no better alternative. what recommendation on how store digraphs? should go different data type altogether? thanks. i not sure understand concern. fact digraph stored in ets transparent in user interface, might want chnge either exchange digr...
