贴两个关于 treeview的
<script language="javascript">
<!--
//初始化选中节点
function initchecknode()
{
var node=TreeView1.getTreeNode("1");
node.setAttribute("Checked","true");
setcheck(node,"true");
FindCheckedFromNode(TreeView1);
}
//oncheck事件
function tree_oncheck(tree)
{
var node=tree.getTreeNode(tree.clickedNodeIndex);
var Pchecked=tree.getTreeNode(tree.clickedNodeIndex).getAttribute("checked");
setcheck(node,Pchecked);
document.all.checked.value="";
document.all.unchecked.value="";
FindCheckedFromNode(TreeView1);
}
//设置子节点选中
function setcheck(node,Pc)
{
var i;
var ChildNode=new Array();
ChildNode=node.getChildren();
if(parseInt(ChildNode.length)==0)
return;
else
{
for(i=0;i<ChildNode.length;i++)
{
var cNode;
cNode=ChildNode[i];
if(parseInt(cNode.getChildren().length)!=0)
setcheck(cNode,Pc);
cNode.setAttribute("Checked",Pc);
}
}
}
//获取所有节点状态
function FindCheckedFromNode(node) {
var i = 0;
var nodes = new Array();
nodes = node.getChildren();
for (i = 0; i < nodes.length; i++) {
var cNode;
cNode=nodes[i];
if (cNode.getAttribute("Checked"))
AddChecked(cNode);
else
AddUnChecked(cNode);
if (parseInt(cNode.getChildren().length) != 0 ) {
FindCheckedFromNode(cNode);
}
}
}
//添加选中节点
function AddChecked(node) {
document.all.checked.value += node.getAttribute("NodeData");
document.all.checked.value += ',';
}
//添加未选中节点
function AddUnChecked(node) {
document.all.unchecked.value += node.getAttribute("NodeData");
document.all.unchecked.value += ',';
}
//-->
</script>
treeview 中如何在服务器端得到客户端设置后的节点选中状态
<script language="C#" runat="server">
private void Button1_Click(object sender, System.EventArgs e)
{
Response.Write(TreeView1.Nodes[0].Checked);
}
</script>
<script language="javascript">
function set_check()
{
var nodeindex = "0";
var node=TreeView1.getTreeNode(nodeindex);
node.setAttribute("Checked","True");
TreeView1.queueEvent('oncheck', nodeindex);
}
</script>
三個實用的小技巧 :關閉輸入法.禁止貼上.禁止複製
關閉輸入法
//================================
//Cookie 操作
//================================
function getCookieVal (offset)

var endstr = document.cookie.indexOf (";", offset);
if (endstr == -1)
endstr = document.cookie.length;
return unescape(document.cookie.substring(offset, endstr));
}
function deleteCookie(cname) {

var d= new Date(r[1], r[3]-1,r[4],r[5],r[6],r[7]);
return (d.getFullYear()==r[1]&&(d.getMonth()+1)==r[3]&&d.getDate()==r[4]&&d.getHours()==r[5]&&d.getMinutes()==r[6]&&d.getSeconds()==r[7]);
}
2.4 只有年和月。形如(2003-05,或者2003-5)
2.5 只有小时和分钟,形如(12:03)
3、表单类
3.1 所有的表单的值都不能为空
<input onblur="if(this.value.replace(/^\s+|\s+$/g,'')=='')alert('不能为空!')">
3.2 多行文本框的值不能为空。
3.3 多行文本框的值不能超过sMaxStrleng
3.4 多行文本框的值不能少于sMixStrleng
3.5 判断单选框是否选择。
3.6 判断复选框是否选择.
3.7 复选框的全选，多选，全不选，反选
3.8 文件上传过程中判断文件类型
4、字符类
4.1 判断字符全部由a-Z或者是A-Z的字字母组成
<input onblur="if(/[^a-zA-Z]/g.test(this.value))alert('有错')">
4.2 判断字符由字母和数字组成。
<input onblur="if(/[^0
4.3 判断字符由字母和数字，下划线,点号组成.且开头的只能是下划线和字母
/^([a-zA-z_]{1})([\w]*)$/g.test(str)
4.4 字符串替换函数.Replace();
5、浏览器类
5.1 判断浏览器的类型
window.navigator.appName
5.2 判断ie的版本
window.navigator.appVersion
5.3 判断客户端的分辨率
window.screen.height; window.screen.width;
6、结合类
6.1 email的判断。
function ismail(mail)
{
return(new RegExp(/^\w+((-\w+)|(\.\w+))*\@[A-Za-z0-9]+((\.|-)[A-Za-z0-9]+)*\.[A-Za-z0-9]+$/).test(mail));
}
6.2 手机号码的验证
6.3 身份证的验证
function isIdCardNo(num)
{
if (isNaN(num)) {alert("输入的不是数字！"); return false;}
var len = num.length, re;
if (len == 15)
re = new RegExp(/^(\d{6})()?(\d{2})(\d{2})(\d{2})(\d{3})$/);
else if (len == 18)
re = new RegExp(/^(\d{6})()?(\d{4})(\d{2})(\d{2})(\d{3})(\d)$/);
else {alert("输入的数字位数不对！"); return false;}
var a = num.match(re);
if (a != null)
{
if (len==15)
{
var D = new Date("19"+a[3]+"/"+a[4]+"/"+a[5]);
var B = D.getYear()==a[3]&&(D.getMonth()+1)==a[4]&&D.getDate()==a[5];
}
else
{
var D = new Date(a[3]+"/"+a[4]+"/"+a[5]);
var B = D.getFullYear()==a[3]&&(D.getMonth()+1)==a[4]&&D.getDate()==a[5];
}
if (!B) {alert("输入的身份证号 "+ a[0] +" 里出生日期不对！"); return false;}
}
return true;

範例： <input type="text" name="textfield" style="ime-mode:disabled">
禁止貼上
本文字框禁止貼上文字：
語法：onpaste="return false"
範例：<input type="text" name="textfield" onpaste="return false">
語法：onpaste="return false"
範例：<input type="text" name="textfield" onpaste="return false">
禁止複製
本文字框禁止複製：
語法：oncopy="return false;" oncut="return false;"
