代码 如下: <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<html>
<head>

解决方案 »

  1.   


    <form id="formfoo" name="formfoo" method="post" runat="server">少个name 属性  name="formfoo"
      

  2.   

    按照标准写法试试。
    function CheckSelect() {
        var tmp = [],
            form = document.getElementById("formfoo"),
            items = form.getElementsByTagName("input");
            
        for(var i = 0,len = items.length;i < len;i++){
            var input = items[i];
            if(input.checked) tmp.push(input.value);
        }
        
        return tmp.join(",");
    }
