我有一个动态表,其中包含来自asp.net应用程序的用户(使用成员资格类)。
我试图在每个角色单元格内添加一个控件,以便使用javascript打开弹出窗口。现在,我只检查该功能是否启动。但是当我单击该单元格时,会发生错误:“未捕获的SyntaxError:意外的令牌}”。

这是我的aspx:

<head runat="server">
    <title></title>
    <script type="text/javascript">
       function alert_function(id)
       {
        alert(id);
       }
    </script>
</head>
<body>
    <form id="form1" runat="server">
    <div>

        <asp:placeholder ID="Placeholder1" runat="server"></asp:placeholder>

    </div>

    </form>
</body>

</html>


和我的代码后面:

protected void Page_Load(object sender, EventArgs e)
    {
        MembershipUserCollection users = Membership.GetAllUsers();

        Table tbl = new Table();

        TableRow h_row = new TableRow();
        TableCell c1 = new TableCell();
        TableCell c2 = new TableCell();
        TableCell c3 = new TableCell();
        TableCell c4 = new TableCell();
        TableCell c5 = new TableCell();
        TableCell c6 = new TableCell();

        c1.Text = "משתמש מחובר?";
        c2.Text = "התחבר לאחרונה";
        c3.Text = "נוצר ב";
        c4.Text = "דואר אלקטרוני";
        c5.Text = "תפקיד";
        c6.Text = "שם משתמש";

        h_row.Controls.Add(c1);
        h_row.Controls.Add(c2);
        h_row.Controls.Add(c3);
        h_row.Controls.Add(c4);
        h_row.Controls.Add(c5);
        h_row.Controls.Add(c6);

        tbl.Controls.Add(h_row);


        foreach (MembershipUser u in users)
        {
            TableRow row1 = new TableRow();
            TableCell cell1 = new TableCell();
            TableCell cell2 = new TableCell();
            TableCell cell3 = new TableCell();
            TableCell cell4 = new TableCell();
            TableCell cell5 = new TableCell();
            TableCell cell6 = new TableCell();

            cell1.Text = u.IsOnline.ToString();
            cell2.Text = u.LastLoginDate.ToString();
            cell3.Text = u.CreationDate.ToString();
            cell4.Text = u.Email;
            string user_name=u.UserName;
            string[] role = Roles.GetRolesForUser(user_name);
            if (role.Length < 1)
                cell5.Text = "אין תפקיד";
            **else
            {
                LiteralControl lc=new LiteralControl("<a onclick='alert_function('"+u.UserName.ToString()+"')'>" + role[0] + "</a>");
                cell5.Controls.Add(lc);
            }**

            cell6.Text = u.UserName;

            row1.Controls.Add(cell1);
            row1.Controls.Add(cell2);
            row1.Controls.Add(cell3);
            row1.Controls.Add(cell4);
            row1.Controls.Add(cell5);
            row1.Controls.Add(cell6);

            tbl.Controls.Add(row1);
        }

        Placeholder1.Controls.Add(tbl);

    }


**这很奇怪,因为当我将代码中的高亮行更改为:

LiteralControl lc=new LiteralControl("<a onclick='alert_function("+u.UserName.ToString()+")'>" + role[0] + "</a>");


(删除“''”),它可以工作,但是用户名不会以字符串形式发送,因此只提醒数字。**

最佳答案

用您的文字转义引号。

LiteralControl lc =
    new LiteralControl("<a onclick='alert_function(\""
        + u.UserName.ToString() + "\")'>" + role[0] + "</a>");


要么

LiteralControl lc =
    new LiteralControl("<a onclick=\"alert_function('"
        +u.UserName.ToString()+"')\">" + role[0] + "</a>");

关于c# - LiteralControl出现意外的 token “}”错误,我们在Stack Overflow上找到一个类似的问题:https://stackoverflow.com/questions/17731148/
