I am using some nested layouts in Ruby on Rails, and in one of the layouts i have a need to read in a string from a div and set that as the title of the document. What is correct way (if any) to set the title of the document?
<script type="text/javascript">
$(document).ready(function() {
// ???
});

Javascript Solutions
Solution 1 - Javascript
The following should work but it wouldn't be SEO compatible. It's best to put the title in the title tag.
<script type="text/javascript">
$(document).ready(function() {
document.title = 'blah';
});
</script>
Solution 2 - Javascript
Do not use $('title').text('hi'), because IE doesn't support it.
It is better to use document.title = 'new title';
Solution 3 - Javascript
This works fine in all browser...
$(document).attr("title", "New Title");
Works in IE too
Solution 4 - Javascript
Like this:
$(document).ready(function ()
{
document.title = "Hello World!";
});
Be sure to set a default-title if you want your site to be properly indexed by search-engines.
A little tip:
$(function ()
{
// this is a shorthand for the whole document-ready thing
// In my opinion, it's more readable
});

<script type="text/javascript">
$(document).ready(function() {
$(this).attr("title", "sometitle");
});
</script>

document.title was not working for me.
Here is another way to do it using JQuery
$('html head').find('title').text("My New Page Title");

The correct way to do this is on the server side.
In your layout, there at some point will be some code which puts the text in the div. Make this code also set some instance variable such as @page_title, and then in your outer layout have it do <%= @page_title || 'Default Title' %>
Solution 8 - Javascript
If you have got a serverside script get_title.php that echoes the current title session this works fine in jQuery:
$.get('get_title.php',function(*respons*){
title=*respons* + 'whatever you want'
$(document).attr('title',title)
})
