jquery - How to interact with a javascript element -


I am using AC editor (via jquery-ace-rails gem) to convert textarea into code editor I am 

  & lt; Textarea class = "my-code-area" rows = "4" style = "width: 100%" & gt; Puts 'foo' & lt; / Textarea & gt; & Lt; Script & gt; $ (Document) .ready (function () {$ ('. My-code-area'). Ace ({subject: 'twilight,' lang: 'ruby'})}}; & lt; / script & gt;   
 I want to create a link on the page to insert text in the editor:  
  & lt;% = link_to 'Insert', '# ',: Onclick =>' ace.insert ("some good"); '& gt%;   
 Any help appreciated - I did not work with Javascript before  
 This can be relevant: especially in the "Access to ACE Code Editor Examples" section.   
 
 
 You can use  ace  by using the property of the data in the  Ace  example  
 Then try jquery ('. My-code-area'). Data ('ace'). Ace.insert ("some good"); Ace.Instant ("some cool");  
 Instead of using inline event handlers, try using jQuery event handlers so add a class or id to the link, then remove the inline event handler  
  jQuery ( Function ($) {$ ('. My-code-area '). Ace ({subject: 'twilight', lang: 'ruby'}); Var decorator = $ ('.my-code-area'). Data ('Ace') Editor; // ACE code editor example var ace = decorator.ac; // Enter the id in the link -international $ ('# insert-link'). Click (function () {ace.insert ("some good");})});

ios - Does Core Data autoupdate a many to many relationship on saving -

I have used 2 database tables and core data / NSManagedObjects in SQLite: User is user_id name group (multiple groups) Group group_id title group members (multiple users) By using core data to save a group and adding users ( Add to group) as follows: group * cordata = zero; Cordata = [NSEntityDescription insertNewObjectForEntityForName: @ Managed Object Contains in "Groups": Reference]; Request = [NSFetchRequest fetchRequestWithEntityName: @ "user"]; Request.predicate = [NSPredicate predicateWithFormat: @ "user_id =% @", user_id]; Result = [reference executeFetchRequest: request error: & amp; Error]; CoreData.group_id = group_id Cordettitle = Title [Cordata AdGroupMailersObject: [Last objections result]]; Is it right to say that core data manages a user with multiple users and groups with the code above? Yes, if the relationships are in the form of each other's inverse relationship The inverse relationships are updated automaticall...

Calling a C++ function from C# by passing a string with variable size to it -

I am calling a string with a C + code and calling from the C # code. The C ++ function is responsible for filling the string material. The following code is: C #party: var abc = new string builder (4096); // will have to change this var result = Basic methods. SignCrcFile (ABC); C ++: bool __cdecl SignCrcFile (char * abc) {... char * tempStr = "hello all"; // for example // copy it to ABC string strcpy (ABC, tempStr); Back true; } The problem is that tempStr's size in the C ++ function is dynamic (the above assignment for TempStr is only an example). In such a case, it is not a hard code that the size of ABC string is in the size of 4096 bytes on the C #. The first solution can be a solution to create 2 functions on the C ++ side to get the size of the string. Then allocate that size using StringBuilder in the C # side then use the next function to bring the entire string from C ++ to the C #. But no suggestion this may not be the most optimal way? ...
