instance name of components created dynamically

Hi,

i try to put 2 or more radiobuttons on the stage dynamically (but the problem is the same for any sort of component : Input text, check boxes ...).

I've made a movieClip with the radiobutton inside, with the name bouton for the component.The link to the MC in the library is Radio. 

So, i've displayed components with :

 

var caseH = new lib.Radio();
var caseF = new lib.Radio();

this.addChild(caseH);
this.addChild(caseF);

 

That works but, after, i try to access one of them : 

caseH = document.getElementById("bouton");
caseF = document.getElementById("bouton"); 
caseH.checked = true;

and, of course, it does'nt work cause all the instances have the same name : bouton ! So, caseH and caseF refere to the same last child added, caseF! 

How can I access to each component  instance ?

 

Thanks for your reply.

    That's great!

     

    Please try:

    alert("caseChg "+evt.target.id);

    thanks for your reply :

    I don't understand what you mean exactly.

    My components are already in a MovieClip in the Library.

    You mean that instead of adding them to stage, i have to add them in one different MC each ?

    Hi.

     

    As you're adding components dynamically, it will be better to rely on the ids that Animate generates automatically for each kind of component. For example:

     

    RadioButton: radiobutton0, radiobutton1, and so on.

    CheckBox: checkbox0, checkbox1, and so on.

     

    So instead of assigning a instance name manually in the IDE, leave that field alone and just reference the components like this:

    var radio0 = document.getElementById("radiobutton0");
var radio1 = document.getElementById("radiobutton1");

     

    I hope it helps.

     

    Regards,

    JC

    thanks Joao,

    effectively, it allows me to do what i want! I did'nt know that animate calls the components with these name, by default.

    And do you know how i can recover this name when an event is called.

    for (i = 0; i <8; i++) {
   var caseacoche= document.getElementById("radiobutton"+i);
   caseacoche.addEventListener("change", caseChg);
}
function caseChg(evt) {
   alert("caseChg "+evt.target.name);
}

    evt.target doesn't work neither this.name neither many other tryings!
