表单筛选核心函数

function Filter(a, b) {
    var $ = function(e) {
        return document.getElementById(e);
    }
    var ipts = $('filterForm').getElementsByTagName('input'), result = [];
    for (var i = 0, l = ipts.length; i < l; i++) {
        if (ipts[i].getAttribute('to') == 'filter') {
            result.push(ipts[i]);
        }
    }
    if ($(a)) {
        $(a).value = b;
        for (var j = 0, len = result.length; j < len; j++) {

            if (result[j].value == '' || result[j].value == '0') {
                result[j].parentNode.removeChild(result[j]);
            }
        }
        document.forms['filterForm'].submit();
    }
    return false;
