我有一个动态表与用户从我的asp.net应用程序(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打开一个弹出窗口。现在我只检查功能是否启动。但是当我单击单元格时发生错误:“未捕获的SyntaxError:意外的令牌}”。意外的令牌“}”与LiteralControl错误
这里是我的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>
和我的代码背后:
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,因为当我改变加亮后行代码:
LiteralControl lc=new LiteralControl("<a onclick='alert_function("+u.UserName.ToString()+")'>" + role[0] + "</a>");
(移除在“”““)它的工作原理,但用户名不派作为一个字符串,因此只有数字被警告。**
如果你使用一个字符串,它需要被引用。数字不需要被引用,否则,JavaScript将它解释为一个变量的引用......这可能没有被定义为 – Ian
但它被引用..这个错误很奇怪.. – Dvirski
你需要看看源代码实际上在浏览器中结束了,从中可以看出问题的原因,很容易。 – Pointy
