Simple way to clear the value of any input inside a div?

Question

Is there a simple way to iterate over the child elements in an element, say a div, and if they are any sort of input (radio, select, text, hidden...) clear their v

Answer 1

Oh boy, this would be a one liner with jQuery:

$(':input:not(:button)', div).val([])

Without jQuery you've got to account for <select> fields, text fields, password fields and radio/checkbox fields:

function clearFields(container) {
    var selects = container.getElementsByTagName('select');

    for(var i=0, len=selects.length; i < len; i++) {
        selects[i].selectedIndex = -1;
    }

    var fields = container.getElementsByTagName('input');
    for(var i=0, len=fields.length; i < len; i++) {
        var field = fields[i];
        switch(field.type)
        {
            case 'radio':
            case 'checkbox':
                field.checked = false;
                break;

            case 'text':
            case 'password':
            case 'hidden':
                field.value = ''
        }
    }

    var fields = container.getElementsByTagName('textarea');
    for(var i=0, len=fields.length; i < len; i++) {
        fields[i].value = ''
    }
}

$('#div_id input[type=textbox], #div_id select, #div_id textarea').val(''); 
$('#div_id input[type=radio], #div_id input[type=checkbox]').prop('checked', false);

for jquery.
