试试用javascrpt调用按钮的click，在按钮的click事件里调用你类里的方法

楼主要干嘛？用javascript直接调是不可能的。即使用2.0里带的异步回调，也要你的页面类里有相应的代码才行

何不尝试js+xmlhttp+handler

我是这样做的,但没用
<%@ Page Language="C#" AutoEventWireup="true" CodeFile="pic.aspx.cs" Inherits="pic" %>

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.

<html xmlns="http://www. >
<head runat="server">
    <title>宜春</title>

</head>
<body>
    <form id="form1" runat="server">
    <div>
       <script type="text/javascript"  src="js/flash.js"></script>

    </div>
    </form>
</body>
</html>

页面代码:

using System;
using System.Data;
using System.Configuration;
using System.Collections;
using System.Web;
using System.Web.Security;
using System.Web.UI;
using System.Web.UI.WebControls;
using System.Web.UI.WebControls.WebParts;
using System.Web.UI.HtmlControls;
using System.Data.SqlClient;

public partial class pic : datacon
{
    protected void Page_Load(object sender, EventArgs e)
    {

        AjaxPro.Utility.RegisterTypeForAjax(typeof(pic));
    }

    [AjaxPro.AjaxMethod]
    public string GET_TYPE_ID(int id, string ids, string tables, string feildname)
    {
        //Open();
        string SQL = "select " + feildname + " from [" + tables+ "]  where " + ids + " = " + id+"";
        return Convert.ToString(parameter_sql.ExecuteScalar(datacon.strcnn, CommandType.Text, SQL, null));
        //SqlCommand cmd = new SqlCommand(SQL, conn);
        //string va = cmd.ExecuteScalar().ToString();
       // return va;
    }
}

js文件

var pic_width=580; //图片宽度

帮忙看看这句哪里有问题:
imag[1]=pic.GET_TYPE_ID(1,"typeid","pic","img");
link[1]="http://www.
text[1]="标题 1";
imag[2]=pic.GET_TYPE_ID(2,"typeid","pic","img");
link[2]="http://www.
text[2]="标题 2";
imag[3]=pic.GET_TYPE_ID(3,"typeid","pic","img");
link[3]="http://www.
text[3]="标题 3";
imag[4]=pic.GET_TYPE_ID(4,"typeid","pic","img");
link[4]="http://www.
text[4]="标题 4";
imag[5]=pic.GET_TYPE_ID(5,"typeid","pic","img");
link[2]="http://www.
text[5]="标题 5";

是不是这个啊
var arr="<%= GET_TYPE_ID（）%>";

#9

ycbbg2008-08-22 15:59

我试了,没用,我用的是ajax调用类的方法

#10

xuezihanfd2008-08-22 16:04

也可以返回个xml
再从中读取出想要的信息不是一样么

#11

tomtory2008-08-25 17:27

不知道是不是你要的：
比如有个类 ResourceBase 此中有一个GetUIText的方法此类的命名控件是

首先在页面上<%@ Import Namespace=" %> 这个表示ResourceBase这个类所在的命名控件
然后调用方法
<%=ResourceBase.GetUIText("参数")%>
这样可以用

#12

ycbbg2008-08-25 17:53

不是呀兄弟，我要的是在javascript中调用，如果要在.net页中调用直接<%=ResourceBase.GetUIText("参数")%>
就可

#13

ycbbg2008-08-27 10:11

问题解决了：pic.GET_TYPE_ID(1,"typeid","pic","img").value

尝试用Ajax 或者觉得麻烦，直接用AjaxPro.dll来做
