名站网址导航为大家提供关于网站网页设计设计相关的的教程知识。
- 本篇文章具体介绍如下
具体代码如下:
<script src="js/jquery-1.4.2.min.js" type="text/javascript"></script>
<script src="js/jquery.mytree.js" type="text/javascript"></script>
<link href="second.css" rel="stylesheet" type="text/css" />
<script type="text/javascript">
$(function(){
var o = { showcheck: true};
o.data =<%=treeNodes %>;
$("#tree").treeview(o);
})
</script>
后台
具体代码如下:
public string GetFirJson()
{
string mystr = "[";
DataTable dt = DBUtility.db.ExecuteTable("select * from class where parientid=0");
int a = dt.Rows.Count;
for (int i = 0; i <= dt.Rows.Count - 1; i )
{
mystr = GetOtherJson(Convert.ToInt32(dt.Rows[i]["classid"].ToString())) ",";
}
mystr = mystr.Substring(0, mystr.Length - 1);
mystr = "]";
mystr = mystr.Replace("'", "\"");
return mystr;
}
//递归
private string GetOtherJson(int pid)
{
DataTable dt = DBUtility.db.ExecuteTable("select * from class where classid=" pid);
string strjson = "";
bool haschild = IshasChild(pid);
strjson = "{";
strjson = "'id':'" pid "',";
strjson = "'text':'" dt.Rows[0]["classname"].ToString() "',";
strjson = "'value':'" dt.Rows[0]["classid"].ToString() "',";
strjson = " 'showcheck':true,";
strjson = " 'complete':true,";
strjson = "'checktate':0,";
strjson = "'hasChildren':" haschild.ToString().ToLower() ",";
strjson = "'ChildNodes':";
if (!IshasChild(pid))
{
strjson = "null}";
}
else
{
strjson = "[";
DataTable mydt = DBUtility.db.ExecuteTable("select * from class where parientid=" pid);
for (int i = 0; i <= mydt.Rows.Count - 1; i )
{
strjson = GetOtherJson(Convert.ToInt32(mydt.Rows[i]["classid"].ToString())) ",";
}
strjson = strjson.Substring(0, strjson.Length - 1);
strjson = "]}";
}
return strjson;
}
private bool IshasChild(int pid)
{
DataTable dt = DBUtility.db.ExecuteTable("select * from class where parientid=" pid);
if (dt.Rows.Count == 0)
{
return false;
}
else
{
return true;
}
}
最后数据库 大家看着建就行了 再次 感谢 不正经哥哥
