The following JavaScript function runs the test object method GoToUsedBookPage (on the Web Extensibility sample Book object) and calls the _util.LogLine method to add an entry to the Microsoft Windows event log indicating that the method ran. 

function GoToUsedBooksPage()
{ // Click the link in the first cell of the third row.
   _elem.rows[3].cells[0].children[1].click();
   _util.LogLine("Running GoToUsedBooksPage.", LogSeverity_Information, 752, 2);
