Javascript / PHP Add Checkbox Values to Input Text

Question

I have a Loop with checkbox values from database and when I check some box I need that the value passes to the input (without submit button);

<?php

        while($row = $sth->fetch()) {

              echo("<input type='checkbox' value='".$row['name']."'>".$row['name']."</option>");
        }
        echo('<input type="text" name="modelos" />');

?>

Thanks

Answer 1

$(":checkbox").click(function(){
    var options="";
    $(":checkbox:checked").each(function(){
        options += $(this).val()+";"; 
    });

    $("input[name='modelos']").val(options);
});
