How do I scroll to the very top of a page?

Using the scrollTo() method which accepts two arguments. Horizontal and vertical pixel positions. Eg. to scrol to the very top :

<a href="javascript:scrollTo(0,0);">

Or to scroll to any part of a page, enter the pixel co-ordinates. scrollTo(10,175)

How do I make a link void of any action?

By using the void() function. Using it in a href tag will cause the link to do nothing, you could then use the onclick event handler to execute another function. Eg.

<a href="void(0);" onclick="alert('Hello')">

How do I nest quotes without JavaScript causing a runtime error?

You must escape them or alternate between single and double quotes. Take a look at the first example which uses alternating quotes.

<a href='#' onclick="alert('Hello')">About </a>

The following example uses the escape character (\) to let the JavaScript engine know that we want the quote printed and is not part of the syntax.

<a href='#' onclick="alert('How\'s your day?')">About </a>

Quotes can be escaped numerous times in any one statement. If you forget to escape your quotes, your scripts will fail. Take a look at this stipped down example :

'You\'re day\'s going well?'

Sometimes you need to print double quotes, in this case, you'd use something like the following :

"Click the link that says \"Start\""
