Does Opera support Javascript?
Yes, it currently supports Javascript 1.1 in it’s entirety apart from the functions to open new windows. As Opera 3.62 for EPOC doesn’t support multiple windows these functions aren’t recognised. Links which only use Javascript to open another window will not work, even though they still appear as links in the page. Depending on the way the page was written, it is sometimes possible to disable Javascript from the Multimedia menu and then follow the link successfully, however some links totally rely on Javascript and won’t work at all. If you do really need to follow these links you’ll have to look at the source and find the name of the linked-to file.
Yes, Opera has an excellent implementation of ECMA-232 (3rd edition), the standardised form of Javascript. ECMAscript 3 is loosely aligned with Javascript 1.4 so most scripts should be compatible with Opera. Problems can arise however, when scripting uses a proprietary Document Object Model rather than the standard W3C DOM, or if the Javascript tries to do something which the Opera 5 browser engine does not support (such as inserting a new row into a table once the page has finished loading).
