Since at the moment there is no way to 'permanently' delete a page from scripts (see this thread http://www.google.com/support/forum/p/apps-script/thread?tid=31e4f73ae642c2b6&hl=en ) a mechanism is needed for those of us that wish to delete a page and then re-use that same url for a new page (as discussed above). I've written the function below and would appreciate any advice as to whether there is a more elegant way of achieving what I'm trying to do. I can see no (easy/efficient) way of finding out if a given page url has been used so I rely on the fact that renaming a page to a url that is 'deleted' but not 'permanently' throws an error. But this feels wrong - there ought to be a way of checking whether an operation will fail before actually doing it. Any suggestions for a better way of doing this ?
function removePage(page) { // renames page before deleting it so thet the URL can be re-used // returns true if successful, false if not var pageSuffix = 1; var pageRenamed = false; var pageName = page.getName(); // pageSuffix check is get out in case error trap fails which would leave us in endless loop while (!pageRenamed && pageSuffix < 100) { try { // rename the page before deleting it so that we can keep the original url // this will fail if the name has been used before - we catch this using the error trap var page = page.setName(pageName+"-"+pageSuffix); // if we get here, page renaming succeeded , so set flag var pageRenamed = true; } catch(err) { // Tried to rename a page to one that has previously been deleted, so keep trying till we succeed pageSuffix++; } } if (pageRenamed) { page.deletePage(); } return pageRenamed; } |
