javascript - Change radio model on button click [angularjs] -


What do I want to achieve, when I click on the button change input, the model of the radio changed "value" goes . Why do I need to double click, so that the model can be updated and the radio is checked? 

  & lt; Div ng-app ng-controller = "Ctrl" & gt; & Lt; Input type = "radio" ng-model = "value" ng-value = "33" & gt; & Lt; Input type = "radio" ng-model = "value" ng-value = "22" & gt; {{Value}} & lt; Button onclick = "changeInput ()" & gt; Input input & lt; / Button & gt; & Lt; / Div & gt;   
 JS  
  function Ctrl ($ scope) {} function changeInput () {$ ('input: eq (0)'). Click () .click (); } 
 
 The probability is because the value is updated before your onclick function. Why do not you update the value in your onclick function and use only one click?

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? ...
