I can't get the checked values of the dynamic check box. What am I doing wrong? http://jsfiddle.net/hxfsB/17/

Markup:

<html>

    <body>

      one<input type=checkbox name='checkbox0' value=one_name checked>

     two<input type=checkbox name='checkbox1' value=one_name1>

     three<input type=checkbox name='checkbox2' value=one_name2>

         <input type=button id=envoyer value=Envoyer Reponse  /> 

    </body>

</html>

Javascript:

$('#envoyer').click(function(e){

    var myArray=new Array(4);

    for ( var j = 0; j < 3; j++){ 

        var check=$('input:checkbox[name=checkbox'+j+']').is(':checked');

        if(check==true)

            myArray[j]=$('input:checkbox[name=checkbox'+j+']').val();

    }

    alert('check '+ +myArray[i]);

});

You had an Uncaught ReferenceError: i is not defined; I've updated your fiddle here:

http://jsfiddle.net/hxfsB/24/

$('#envoyer').click(function(e){

    var myArray = new Array(3);

    for ( var j = 0; j < 3; j++) { 

        var check=$('input:checkbox[name=checkbox'+j+']').is(':checked');

        if(check==true)

            myArray[j]=$('input:checkbox[name=checkbox'+j+']').val();



        // Alert Current Selection //

        alert('check ' +   + myArray[j] );

    }    

});

Keep in mind: undefined means the checkbox is NOT selected.

I hope this helps!
