Controlling where a script is placed

Nathan Sokalski · Mar 15, 2009

We all know that Page.ClientScript has several ways to register scripts, but
none of them seem to do what they should. For example, how do I put at
script in the <head> section using Page.ClientScript? Shouldn't stuff added
using RegisterStartupScript be executed before stuff added using
RegisterClientScriptBlock? Can someone give me a summary or good reference
as to where the different methods actually put the scripts? Thanks.

its pretty simple. RegisterScriptBlock, goes right after the <form>.
RegisterStartupScript goes right before the </form>. there is no support
for placing script in the <head>.

A startup-script should fire on startup and be able to access all
controls on the page (if required), so it must be fired *after* all
controls on the page are loaded. That is why it is rendered ar the
*end* of the page, instead of (as you would expect) at the start of the
page.

RegisterClientScript is meant for blocks of javascript that should be
"available" when needed, therefore it is rendered first on the page.

Look at this class Nathan [1] and if push comes to shove put a literal, a
label or a ContentPlaceHolder into the head and then reference and write to
it. This can get really ugly if you made the mistake to use Themes.

Remember, you are the organ grinder and sometimes you have to fool the
monkey.
