1)在这里我正在克隆一行......但是这段代码只在eclipse中工作[即,克隆工作]而且它也不能在任何浏览器中工作。
2)如何获取克隆行中文本框的值,并使用jsp和servlet插入数据库?我怎样才能获得具有相同名称的那些值
3)我有servlet代码从jsp只获取单个值
String address_seq_num =request.getParameter("address_seq_num");
how can i get the value of address seq number in the cloned row fromjsp to servlet to insert into the next row of a table in the database.
4)如果我在这段代码中提到“文档类型”,它在eclipse中也不起作用.....请指导我......
JavaScript
function clonetable() {
var x=document.getElementById("main_table"); //get the table
var rowCount = x.rows.length;
var row = document.getElementById("table_row_clone"); // find row to copy
var table = document.getElementById("table_body"); // find table to append to
var clone = row.cloneNode(true); // copy children too
var tb1 = clone.document.getElementById("asn");//here i'm incrementing the value
tb1.value=rowCount+1;//of "address seq num " in the cloned row
clone.id = "abc"; // change id or other attributes/contents
table.appendChild(clone); // add new row to end of table
}
function deltable() {
var x = document.getElementById("main_table"); //get the table
var rowCount = x.rows.length;
if (rowCount > 1) {
x.deleteRow(rowCount - 1);
} //delete the last row
}
