js无刷新操作table的行和列_javascript技巧

代码仅供参考 如果强行复制请修改页面id

复制代码 代码如下:

//查询数据库符合条件的数据
function SelectAlterNativeVenues(field)
{
var xmlhttp;
var pid = document.getElementById("nameandaddress").value;
var url = "${RetrieveURL}?accessorType=${AccessorType}";
url = url "&method=RetrieveSelectResult&NameAndAddress=" escape(pid);
if (window.XMLHttpRequest)
{
xmlhttp = new XMLHttpRequest();
}
else if (window.ActiveXObject)
{
xmlhttp = new ActiveXObject("Microsoft.XMLHTTP"); //IE
}
if (xmlhttp != null)
{
xmlhttp.open("GET", url, true);
xmlhttp.setRequestHeader("If-Modified-Since", "0");
xmlhttp.send(null);
xmlhttp.onreadystatechange = function processRefreshUsers() //注册方法
{
if (xmlhttp.readyState == 4)
{
if (xmlhttp.status == 200)
{
//responseXML获取执行RetrieveCitiesByProvinceId方法的返回值
var datas = xmlhttp.responseXML.documentElement.getElementsByTagName("AlterNativeVenues");
var nname = document.getElementById("table1");
var pchildren = nname.childNodes;//清空表中的行和列
