How to get inner text of a DIV controller using java script?
The short answer:
document.getElementById("id-of-div").innerText
The long answer, given that you've tagged the question with asp.net-mvc-3, is that this will be run in the browser, not on the server (where ASP.NET runs). There is no immediate way to get content from the browser to the server without sending a request. I'm guessing that you may want to make an ajax call to a new controller action from the page, but this depends on when the text changes, and what you want to do with it.
Suppose you have a div declared as:
<div id="someDiv">
some content goes here
</div>
You can get its value by:
// javascript
document.getElementById("someDiv").innerHTML
// jquery
$("#someDiv").html()

execute function after complete page load [duplicate]

I am in need of some JS assistance.
I need to run some code after the DOM was updated.
For example: when I click a button, it fires a function. I need to run that function code and when the DOM is fully updated, run some more code. How could I go about doing this in a clean fashion?
I am sure this is relatively simple but I am drawing blanks. I am using jQuery.
$('.btn').click(function() {
do some stuff
// then ensure dom has fully updated and do some more????
})
DOM updates are synchronous. Just put the code where your comment is.

The comment by Sico refers to an existing question on stack that answers this as not possible. How to change style of iframe content cross-domain?
If you are looking to do this in Javascript or JQuery that answer is correct, basically. You Cannot. It is not possible to alter the content of another domain.
A solution however, would be to use PHP to fetch the content of the target page and make it your own, there are several ways to do this such as curl http://php.net/manual/en/book.curl.php. You can then redisplay that content in any manner you like and apply any style you like. You can even ditch the iframe and inline it right into the rest of your content.
Be warned however, depending on the source domain, they may not approve of their content being re-used in this manner.

How to dynamically change a web page's title?
I am trying to set the title of my web page using JavaScript because I want something that is stored in localStorage to be part of the title. The approach that I am trying is to use document.createElement('title'), but I cannot set the text of the title when I do that. Is there a way to set the text of the title this way or is there a different way that I should be doing this?
Use
document.title = 'Your desired title';
Your site should have a <title> element
If it does, you simply add this to your scripts and call it
function changeTitle(title) { document.title = title; }
The question is why are you doing it?
You can just do something like, document.title = "This is the new page title.";, but this would not work for seo etc, as most crawlers do not support JavaScript.
If you want this to be compatible with most of the important crawlers, you're going to need to actually change the title tag itself, on the server side which would involve (PHP, or the like).

How do I change the text of a span element in javascript
Well, I've searched a lot for the answer to this, but still I couldn't find it. What I did find didn't work.
What I'm trying to do is, basically, using JavaScript: At the browser's bar, not via Greasemonkey or something else, edit a span's text .
This' the span that contains the text I want to edit:
<span id="serverTime">5:46:40</span>
The time within is just random, don't pay attention to it, it's what I want to edit using javascript..
I'm a newbie so yeah :\
document.getElementById("serverTime").innerHTML = ...;
Replace whatever is in the address bar with this:
javascript:document.getElementById('serverTime').innerHTML='[text here]';
Example.
