using System.Web.UI.WebControls;
namespace Web
{
public partial class getDepartment : System.Web.UI.Page
{
protected void Page_Load(object sender, EventArgs e)
{
string result = null;
result = "{rows:[{'Name':'开发部', 'Code':'1'}, {'Name':'销售部', 'Code':'2'}, {'Name':'行政部', 'Code':'3'}, {'Name':'质检部', 'Code':'4'}]}";
HttpContext.Current.Response.ContentType = "text/plain";
HttpContext.Current.Response.Write(result);
// Response.Write(result);
}
}
}
下拉框得不到数据，请问这段代码哪里有错误?
------解决方案--------------------
代码应该没有问题 确定store里面有数据吗？
加这句试试看有没有数据返回
dstore.load({callback:function(){
alert("Test the return record num", "共获得" + dstore.getCount() + "条数据");
}});
