Update Title Tag Using Javascript

I've had help from StackOverflow to generate this JavaScript to use in a GreaseMonkey script, which replaces an image with an H1 tag, to use on an Oracle E-Business Suite system where the instance name is held in an H1 tag:

// current page
var url_loc = window.location.href;

if (url_loc.indexOf("http://this.site:0123") == 0) { var env_label = "LIVE";}
if (url_loc.indexOf("http://this.site:1234") == 0) { var env_label = "TEST1";}
if (url_loc.indexOf("http://this.site:2345") == 0) { var env_label = "TEST2";}
if (url_loc.indexOf("http://this.site:3456") == 0) { var env_label = "TEST3";}
if (url_loc.indexOf("http://this.site:4567") == 0) { var env_label = "TEST4";}
if (url_loc.indexOf("http://this.site:5678") == 0) { var env_label = "TEST5";}

var imgs=document.getElementsByTagName('img');
for(var i=imgs.length-1;i>=0;i--){
    if(imgs[i].title == 'NEW_UNI_LOGO.png' || imgs[i].title == 'Oracle') {
      var h1 = document.createElement('h1');
      h1.innerHTML = env_label;
      imgs[i].parentNode.insertBefore( h1, imgs[i] );
      imgs[i].parentNode.removeChild(imgs[i]);
      h1.style.color = "red";
    }
}

It would be really useful to also update the Title tag on the page to start with the env_label value. I don't want to replace all of the content of the Title tag, so that e.g. if the Title is:

<title>Oracle Applications Home Page</title>

I'd like to change it to e.g. for the Live Site:

<title>LIVE: Oracle Applications Home Page</title>

Basically just append env_label to the start of whatever is held in the title tag.

Thanks

Try this..

 document.title = "Oracle Applications Home Page";

Appending the label to the title..

document.title =env_label  + ": Oracle Applications Home Page";

Did you even try something before asking to it ? I can't think about a more simple problem ...

document.title = env_label + ": " + document.title;
