javascript警报asp.net中的服务器端变量

Question

I want to access the server side variable in javascript alert.

 <asp:Button id="btnDelete" runat="server" class="deleteicon" Text='<%# Eval("iuser_id") %>' OnClick="deleteclick" onclientclick="return confirm('Are you sure you want to delete this record?'+<%# Eval("struser_name") %>);"/>

This is a delete button in a gridview. On click of it I want to alert the message and the user name. I am getting server tag is not formattted error.

Thanks,

Answer 1

EDIT

Attach javascript click function in rowDataBound event of the gridview safest and easy way to do it...code is as below

protected void GridView1_RowDataBond(object source, GridViewRowEventArgs e) 
    { 
        if (e.Row.RowType == DataControlRowType.DataRow) 
        { 
            Button btnAlertStatus = (Button)e.Row.FindControl("btnAlertStatus"); 

            DataRowView drv = (DataRowView)e.Row.DataItem; 

            string username = drv["User_name"].ToString(); 

            btnAlertStatus.Attributes.Add("onclick", "return confirm('Are you sure you want to delete this record?"+ username + "')"); //error because of javascript left one bracket
        } 
    }

PRE

Try

JavaScript

function confirmMsg()
{

  var Variable = '<%= ServerVaraible %>';
  return confirm('Are you sure you want to delete this record?'+ Variable );
}

HTML

 <asp:Button id="btnDelete" runat="server" class="deleteicon" Text='<%# Eval("iuser_id") %>' OnClick="deleteclick" onclientclick="return confirmMsg();"/>

 <asp:Button id="btnDelete" runat="server" class="deleteicon" Text='<%# Eval("iuser_id") %>' OnClick="deleteclick" onclientclick='return confirm("Are you sure you want to delete this record? <%# Eval("struser_name") %>");'/>
