Announcement banner depending on page visited Edited

[Leirbag_Assuab]

Hi! I have developed a custom announcement banner depending on page visited using an easy frontend coding (html+js+jquery). In my case, I wanted to advise users about login issues on login page. And once logged, advise them about programmed Jira reboot but only on dashboard pages.

This is how I coded announcement banner:

<script type="text/javascript">
(function($) {
.....
    AJS.toInit(function(){
        // init on load
        .....
        if (($('#login-form').length === 1) || ($('#loginform').length === 1)) {
            $('#alert-ACME-ldap').fadeIn(2500);
        } else if ($(location).attr('pathname').indexOf("Dashboard.jspa") !== -1) {
            $('#alert-ACME-reboot').show();
        }
    });
    .....
})(AJS.$);
</script>
<div id="alert-ACME-ldap" style="display: none;">
  <div id="aui-flag-container"><div class="aui-flag" aria-hidden="false" id="upgrade-notification" application="JIRA" severity="warning"><div class="aui-message aui-message-warning warning closeable shadowed"><div class="body">We are working to solve intermittent problems with the Active Directory. That is why JIRA may not let you authenticate. If so, try again in a few minutes and apologize for any inconvenience!</div></div></div></div>
</div>
<div id="alert-ACME-reboot" style="display: none;">
  <div id="aui-flag-container"><div class="aui-flag" aria-hidden="false" id="upgrade-notification" application="JIRA" severity="warning"><div class="aui-message aui-message-warning warning closeable shadowed"><div class="body">Today <b>OCT-9th</b> at <b>16:15h</b> JIRA will be restarted due to maintenance tasks. The downtime will last about 15 minutes. Sorry for any inconvenience caused.</div></div></div></div>
</div>

I would like to share it with this community because maybe could be useful to someone. I also would like to know the opinion of you experts and any advices to correct or improve this code will be welcome.
