c# - javascript警报asp.net中的服务器端变量

Question

我想在 javascript 警报中访问服务器端变量。

 <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") %>);"/>

这是网格视图中的删除按钮。单击它时，我想提醒消息和用户名。我收到服务器标签未格式化错误。

谢谢，

在gridview的rowDataBound事件中附加javascript单击功能最安全，最简单的方法...代码如下

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
        } 
    }

预

尝试

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();"/>

Answer 2

 <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") %>");'/>

更新。尝试更改引号
