Answer 1

To Get Page Title

You can use (SP.js) to Get Web Site Properties like Title, Description, Language ....etc.

<script src="http://ajax.googleapis.com/ajax/libs/jquery/1.9.1/jquery.min.js"></script>
<script type="text/javascript">

$(document).ready(function () {
    // Wait until SP.JS has loaded before calling getWebUserData 
    ExecuteOrDelayUntilScriptLoaded(retrieveWebSite, "sp.js");
});

function retrieveWebSite() {
   var clientContext = new SP.ClientContext("http://epm/workflow");
   this.oWebsite = clientContext.get_web();
   clientContext.load(this.oWebsite);
   clientContext.executeQueryAsync(
      Function.createDelegate(this, this.onQuerySucceeded), 
      Function.createDelegate(this, this.onQueryFailed)
    );
}

function onQuerySucceeded(sender, args) {
   alert('Title: ' + this.oWebsite.get_title());
}

function onQueryFailed(sender, args) {
  alert('Request failed. ' + args.get_message() + 
      '\n' + args.get_stackTrace());
} 
</script>
