Aspx.cs代码
复制代码 代码如下:
protected void Page_Load(object sender, EventArgs e)
{
SoLe.Common.StringFormat sft = new SoLe.Common.StringFormat();
string AreaId = sft.Html_Fn(Request.QueryString["AreaId"].ToString());
StringBuilder AreaString = new StringBuilder();
AreaString.Append("");
if (!Page.IsPostBack)
{
//Response.Write(AreaIdValid(AreaId.ToString()));
SoLe.BLL.AreaTable bll = new SoLe.BLL.AreaTable();
DataSet ds = new DataSet();
ds = bll.GetList(" PaterId=" + AreaId.ToString()+" ");
if (!object.Equals(ds, null) && ds.Tables[0].Rows.Count > 0) {
for (int i = 0; i < ds.Tables[0].Rows.Count; i++) {
if (string.IsNullOrEmpty(AreaString.ToString()))
{
AreaString.Append(ds.Tables[0].Rows[i]["Title"].ToString() + "," + ds.Tables[0].Rows[i]["Id"].ToString());
}
else {
AreaString.Append("|" + ds.Tables[0].Rows[i]["Title"].ToString() + "," + ds.Tables[0].Rows[i]["Id"].ToString());
}
}
}
}
Response.Write(AreaString.ToString());
}
JavaScript分割字符串装载到DropDownList
假设变量str存放着几组对应的数据，DropDownList名为ddlType，把字符分隔后的数据装载到ddlType，具体代码如下：
程序代码
复制代码 代码如下:
<script language="javascript">
function LoadType() {
var str = "1|网页|2|图片|3|企业|4|资讯|";
var temp = str.split("|");
var count = (temp.length - 1) / 2;
for (var i = 0; i <= count; i++) {
document.all("ddlType").options.add(new Option(temp[i], temp[i + 1]));
}
return;
}
<script>
