以下为从不同部门ddlSsbm中选择不同的责任人ddlZrr
1.新建类
public Cfunction()
{
//
// TODO: 在此处添加构造函数逻辑
//
}
public static DataSet getSsbm(string strYgid)//得到所属部门,其它页面可直接用,见后面的调用
{
pub mpub = new pub();
return mpub.getBm1(strYgid);
}
public static DataSet getZrr(string strZrr)//得到责任人.
{
pub mpub = new pub();
return mpub.getBmyg1("0",strZrr);
}
[Ajax.AjaxMethod(Ajax.HttpSessionStateRequirement.Read)]
public DataSet getBmZrr(string strBmdm,string strYgid)//根据所属部门值返回责任人
{
pub mpub = new pub();
return mpub.getBmyg1(strBmdm,strYgid);
}
}
2.在使用的页面后台中加入
private void Page_Load(object sender, System.EventArgs e)
{
Ajax.Utility.RegisterTypeForAjax(typeof(Cfunction));
if(!this.IsPostBack)
{
this.ddlSsbm.DataSource = Cfunction.getSsbm(strYgid);
this.ddlSsbm.DataTextField = "BMMC";
this.ddlSsbm.DataValueField = "BMDM";
this.ddlSsbm.DataBind();
this.ddlZrr.DataSource = Cfunction.getZrr(strYgid);
this.ddlZrr.DataTextField = "YGXM";
this.ddlZrr.DataValueField = "YGID";
this.ddlZrr.DataBind();
this.ddlSsbm.Attributes.Add("onclick","ssbmResult();");
}
}
3.页面的前台加入
<1>对应后台的红字,并在事件后新增事件参数get_bmZrr
function ssbmResult()
{ var bm=document.getElementById("ddlSsbm");
var ygid=document.getElementById("ygid");
Cfunction.getBmZrr(bm.value,ygid.value,get_bmZrr); }
<2>从取得的值加入ddlZrr
function get_bmZrr(response)
{ if (response.value != null) { document.all("ddlZrr").length=0; var ds = response.value; if(ds != null && typeof(ds) == "object" && ds.Tables != null) { for(var i=0;i<ds.tables[0].rows.length;i++)
var name=ds.tables[0].rows[i].YGXM;
var id=ds.tables[0].rows[i].YGID;
document.all("ddlZrr").option.add(new option(name,id));
}
