Question

What I want to achieve is populating many form fields with the same value. I can do it for an element that has an id:

function selectDateAndArendeSearch(year, month, day, field, number, numberfield) {
    var m = parseInt(month)+1;

    if(m<10)
        month="0"+m;
    else
        month=m;
    if(day.length==1)
        day="0"+day;

    document.actionForm.all(field).value = year+"-"+month+"-"+day;
    document.actionForm.all(numberfield).value = number;
    document.getElementById('popupF').style.display = 'none';
}

But how do I do it for many elements i.e. a class?

Answer 1

document.getElementsByClassName('myclassname').value = 'New Value';
