Refreshing a Large Block of the Page
There is often the need to refresh a section of the page without a full page refresh. In this case there are some helpful javascript functions. In particular, the getElementHtml function is optimized to replace the innerHTML of the given div id with the response from the given url. If the div id is in the response, only the innerHTML of the div will be used as the replacement. See the jsDoc for more information about this function:.
getElementHtml( params, divId, true, url)
