防止主页重定向

Question

我点击一个按钮使用此javascript

protected void btn_----_Click(object sender, EventArgs e) 
{ 
    string response = ""; 
    for (int i = 0; i < mylist.Count; i++) 
    { 
     if (mylist[i].id == ddl_idList.SelectedValue) 
     { 
      Session["selectedidObj"] = mylist[i]; 
      response = "<script>window.open('../folder/mypage.aspx','_blank');</script>"; 
      break; 
     } 
    } 

    Response.Write(response); 
} 

的代码工作与物体传递到页面预期（在新窗口中打开），打开一个新窗口

但是，当新窗口关闭，它会导致主页进行快速刷新，这是很烦人看到。

如何防止页面在新窗口页面关闭后刷新？

Answer 1

使用registerclientscriptblock;

protected void btn_----_Click(object sender, EventArgs e) 
{ 
    string response = ""; 
    for (int i = 0; i < mylist.Count; i++) 
    { 
     if (mylist[i].id == ddl_idList.SelectedValue) 
     { 
      Session["selectedidObj"] = mylist[i]; 
      response = "window.open('../folder/mypage.aspx','_blank');"; 
      break; 
     } 
    } 

    ClientScript.RegisterClientScriptBlock(GetType(), "Comment", response, true); 
}
