2)$sel->run_script($script)
Creates a new "script" tag in the body of the current test window, and
+ adds the specified text into the body of the command. Scripts run in
+this way can often be debugged more easily than scripts executed usin
+gSelenium's "getEval" command. Beware that JS exceptions thrown in th
+ese scripttags aren't managed by Selenium, so you should probably wra
+p your scriptin try/catch blocks if there is any chance that the scri
+pt will throwan exception.
