I am having a hard time understanding why a script is running correctly
when a debugging *alert*() statement is present, but no longer functions
when I remove it.
Below, I have reduced the problem to its essence. On Google searches, the
script attempts to insert "Hey there!" just above the search results (div
id *sprvd*).
This works perfectly when I run a search from the Firefox search bar (which
passes the query parameters via GET). But when I run the search by first
opening Google.com, and post the query in the search box, the *Hey there! *is
not displayed... Unless I uncomment the *alert() *line, which confirms that
the script is running, then correctly shows the results preceded by
*Hey there!*(Even when *Hey there!* does not display, Firebug confirms that
the sprvd div is present.)
Why does adding an *alert()* cause the script to work? Does it have
something to do with giving more time to the page to load completely? If so
how can I do the same without an alert
*?*Would be much grateful for any insights!

var start_of_results = /(?=<div id="sprvd")/;
document.body.innerHTML= document.body.innerHTML.replace(start_of_results,
'hey there' + '$&' );
})();
