The value of location.search is "?pg=q&kl=XX&stype=stext&q=free+javascript". Note that you can set the search property at any time, although it is safer to set the href property to change a location.

In order to retrieve the actual query string, we must get rid of the preceding question mark. The following expression chops the question mark:

var str = location.search.substring(1, location.search.length);
