Ajax中调用javaScript

原文地址：http://www.cnblogs.com/carekee/articles/1740124.html

因为用的是Ajax的  ScriptManager +　UpdatePanel控件

所以调用Response.Write(),Page.RegisterStartScript()等方法，就不行了

需要调用Ajax本身的ScriptManager.RegisterStartupScript（）方法；

具体格式为：

System.Web.UI.ScriptManager.RegisterStartupScript（Control control, Type type, string key,string script, bool addScriptTags）

调用方式为：

System.Web.UI.ScriptManager.RegisterStartupScript（this,this.GetType(),"KEY","alert('ss')",true);

 

现在项目中用到的列出几个，以后可能用到的：

AjaxFunc.cs

 

/// <summary>
/// MSG 的摘要说明
/// </summary>
public static class AjaxFunc
{
    /// <summary>
    /// 弹出对话框
    /// </summary>

    /// <param name="strName"></param>
    /// <param name="strMsg"></param>
    public static void MessageBox(Page ps, string strName, string strMsg)
    {
        ScriptManager.RegisterClientScriptBlock(ps, ps.GetType(), strName, "alert('" + strMsg + "')", true);
    }

    /// <summary>

    }

        System.Web.UI.ScriptManager.RegisterStartupScript(ps, ps.GetType(), strName, "window.showModalDialog ('" + strUrl + "', 'newwindow', 'dialogHeight:" + height.ToString() + "px; dialogWidth:" + width.ToString() + "px; toolbar:no; resizable:no; location:no; status:no;help:no;scroll:no;');", true);
    }

    {

    }

 

方法的调用：

AjaxFunc.ResponseWrite(this, this.GetType(), "alert('请登录后再使用该系统！');parent.document.location.href('../default.aspx');", true);

JS解释：

alert('请登录后再使用该系统！');弹出消息框

parent.document.location.href('../default.aspx');打开指定页

 

AjaxFunc.MessageBox(this, "Error", "输入旧密码不能为空！");

JS解释：弹出消息框

 

AjaxFunc.OpenModelUrl_EX(this.Page, "", "ShowCurveLine.aspx", 840, 550);

JS解释：打开模式页面

 

AjaxFunc.OpenModelUrl_EX(this.Page, "", "ShowCurveLine.aspx", 840, 550);

JS解释：打开非模式页面
