treeview中如何在服務器端得到客戶端設置后的節點選中狀態
<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);
}

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


本文字框輸入法被關閉：
語法： style="ime-mode:disabled"
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：οnpaste="return false"
範例：<input type="text" name="textfield" οnpaste="return false">


禁止複製


本文字框禁止複製：
語法：οncοpy="return false;" oncut="return false;"
範例：<input name="textfield" type="text" value="不能複製裡面的字" οncοpy="return false;" oncut="return false;">


//================================
//Cookie操作

function getCookieVal (offset)
{
var endstr = document.cookie.indexOf (";", offset);
if (endstr == -1)

return unescape(document.cookie.substring(offset, endstr));
}


function GetCookie (name)
{
var arg = name + "=";
var alen = arg.length;
var clen = document.cookie.length;
var i = 0;
while (i < clen)
{
var j = i + alen;
if (document.cookie.substring(i, j) == arg)

return getCookieVal (j);
i = document.cookie.indexOf(" ", i) + 1;
if (i == 0)

}
return null;
}


function deleteCookie(cname) {


var expdate = new Date();
expdate.setTime(expdate.getTime() - (24 * 60 * 60 * 1000 * 369));


// document.cookie =" ckValue="ok"; expires="+ expdate.toGMTString();
setCookie(cname,"",expdate);


}


function setCookie (name, value, expires) {

}
