                        <td>{{$val.Jid}}</td>
                        <td>{{.LoginTimeMap[$val.Jid]}}
                    </tr>

it saids the [] in {{.LoginTimeMap[$val.Jid]}} is unexpected bad character U+005B '[' in command

Answer 1

In templates, use index instead of [].

http://golang.org/pkg/text/template/#hdr-Functions

index

Returns the result of indexing its first argument by the following arguments. Thus "index x 1 2 3" is, in Go syntax, x[1][2][3]. Each indexed item must be a map, slice, or array.
