js遍历页面所有控件（部分控件）

到最后 ，终于在后台无法遍历出来控件在前台遍历了出来

  <script type="text/javascript">

 

        function delMessage() {

            //            var e = document.getElementsByTagName("input");

            var flag = 0;

            var e = document.all;

上边这一句是遍历所有的的控件

            //            for (i = 0; i < arrAll.length; i++) {

            //               

            //                if (arrAll[i].id == '... ') {

            //                    //   do   something  

            //                }

            //            }

            for (var i = 0; i < e.length; i++) {

                if (e[i].type == "checkbox") {

                    if (e[i].checked == true) {

                        var id = e[i].id.toString();

                        document.getElementById("myValue").value += id+"|";

                    }

                }

                if (e[i].type == "radio") {

                    if (e[i].checked == true) {

我的JS很弱，需要强硬的补上来，共同努力，共同进步，只是希望做网页和编程的我们，少走一点弯路。多一些灵感

 

                        var id = e[i].id.toString();

                        document.getElementById("myValue").value += id+"|";

                    }

                }

            }

            //            document.getElementById("Label1").val() = e[i].id.toString();

            document.getElementById("Label1").text = document.getElementById("myValue").value;

        }

       

    </script>
