javascript - How do I properly show/hide elements after an AJAX call using jQuery? -

-

what i'm using requires 2 clicks each action:

  • first click: logs nothing, nothing
  • second: logs doesn't exist, element displays
  • third: (2) exists, element doesn't toggle
  • fourth: (5) exists, element toggles
  • fifth: (9) exists, element doesn't toggle
  • sixth: (14) exists, element toggles

what's causing weird behavior?

# views/articles/description.js.erb $(function() {     return $("#link-<%= @article.id %>").on("click", function(e, data, status, xhr) {       e.preventdefault();        var description = '<p class="article__description"><%= j @article.description %></p>';        if ($("#article-<%= @article.id %> .article__description").length) {         console.log("exists");         $("#article-<%= @article.id %> .article__description").toggle();       } else {         console.log("doesn't exist");         $("#article-<%= @article.id %> .article__info").prepend(description);       }     }); });  # views/articles/_article.html.erb <div id="article-<%= article.id %>">   <div class="article__expand">     <%= link_to "show description", description_article_path(article), remote: true, id: "link-#{article.id}" %>   </div>   <div class="article__info"></div> </div>

here's html output, first element without.

<div id="article-5">   <div class="article__expand">     <a id="link-5" data-remote="true" href="articles/5/description">       show description     </a>   </div>   <div class="article__info">   </div> </div>  <div id="article-5">   <div class="article__expand">     <a id="link-5" data-remote="true" href="articles/5/description">       show description     </a>   </div>   <div class="article__info">     <p class="article__description">lorem ipsum</p>   </div> </div>

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.
