为什么这段js在本地正常，发布都服务器上就出错了呢！求解
代码如下：

JScript code


 <script language="javascript">
        var getFromParent = window.dialogArguments;
        function CheckSelect() {
            var aaaa = "";
            for (var i = 0; i < window.document.formfoo.elements.length; i++) {
                var e = this.formfoo.elements[i];
                if (e.checked) {
                    if (aaaa == "") {
                        aaaa = e.value;
                    }
                    else {
                        aaaa = aaaa + "," + e.value;
                    }
                }
            }
            return aaaa;
        }

        function sendFromChild() {
            window.returnValue = CheckSelect();
            window.close();
        }

        function CCC() {
            window.returnValue = "";
            window.close();
        } 
    </script>

放到服务器上会出现window.document.formfoo 为空或不是对象的错误，这个页面是弹出层，弹出这个网页的那种弹出层

整个页面代码如下
