javascript bucle a través de una cadena delimitada
var str = 'Hello, World, etc';
var str_array = str.split(',');
for(var i = 0; i < str_array.length; i++) {
// Trim the excess whitespace.
str_array[i] = str_array[i].replace(/^\s*/, "").replace(/\s*$/, "");
// Add additional code here, such as:
alert(str_array[i]);
}
