jquery - Change Css Class of Same Id which is more than one Id with same name in html page -

-

i want change css class same id appear more 1 in page. try when there 2 id same name reflect first id not other.

i try:

view page : <i id="{{obj.id}}"></i>

controller

$(getjson.id).removeclass('busy b-white bottom');

$(getjson.id).addclass('on b-white bottom');

so, how can achieve ?

► first of id must unique.

when ever using id same name , try use class instead of that.

your solution 

$('[id='+getjson.id+']').removeclass('busy b-white bottom').addclass('on b-white bottom');

this simple method tho select elements same id.

$('[id=test]').removeclass('yellow').addclass('red')
.yellow{    background-color:yellow;  }  .red{    background-color:red;  }
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>  <p id="test" class="yellow">q</p>  <p id="test" class="yellow">w</p>  <p id="test" class="yellow">e</p>

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()? ...

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.
