Site settings JavaScipt

Question

I have included some javascript to a master page of a site collection. The script makes a clickable button directs to two sites which when an internal user click on it user directs to a internal accessible site while an external user click it directs to a external accessible site.

This button appears in all the sites except when I go to the site settings page of a particular site page.

Does that means the script is not working in site settings page? It works in site settings when I activate SharePoint Server Publishing feature in site features.

I'll add the code below you to clarify the issue

<script type="text/javascript">
var clientContext;
var user;

SP.SOD.executeFunc('sp.js', 'SP.ClientContext', sharePointReady);

function sharePointReady() {


    clientContext = SP.ClientContext.get_current();

    user = clientContext.get_web().get_currentUser();

    clientContext.load(user);
    clientContext.executeQueryAsync(onQuerySucceeded, onQueryFailed);
}
function onQuerySucceeded() {

var cuser = user.get_email();
userem = cuser.replace(/.*@/, "");


if (userem == "xxx.com") {

document.getElementById("homehelp").innerHTML = "<a id='bookmarkmy' href='site url for internal users' title='Click here for help with this portal' target='_blank'><img src='image url' width='20px' height='20px' style='margin-bottom:-5px;'>&nbsp;&nbsp;HELP</a>";

} else { 
  document.getElementById("homehelp").innerHTML = "<a id='bookmarkmy' href='site url for external users' title='Click here for help with this portal' target='_blank'><img src='image url' width='20px' height='20px' style='margin-bottom:-5px;'>&nbsp;&nbsp;HELP</a>";
}


}
function onQueryFailed(sender, args) {
    alert('Error: ' + args.get_message());
}
</script>

Answer 1

Yes. You are needed to activate this feature to achieve your goal. It is clearly mentioned in that feature. Have a look on the description of this feature.

SharePoint Server Publishing Infrastructure:

Provides centralized libraries, content types, master pages and page layouts and enables page scheduling and other publishing functionality for a site collection.

Moreover check this answer

if (userem == "xxx.com") {

document.getElementById("homehelp").innerHTML = "<a id='bookmarkmy' href='site url for internal users' title='Click here for help with this portal' target='_blank'><img src='image url' width='20px' height='20px' style='margin-bottom:-5px;'>&nbsp;&nbsp;HELP</a>";

} else { 
  document.getElementById("homehelp").innerHTML = "<a id='bookmarkmy' href='site url for external users' title='Click here for help with this portal' target='_blank'><img src='image url' width='20px' height='20px' style='margin-bottom:-5px;'>&nbsp;&nbsp;HELP</a>";
}

homehelp may not exist in Site Settings page. Check it.

Answer 2

It looks like the Site Settings page doesn't load sp.js.

Try adding this before your script:

<script type="text/javascript" src="_layouts/15/sp.runtime.js"></script>
<script type="text/javascript" src="_layouts/15/sp.js"></script>
