I just uploaded a new version of my JavaScript plugin for jEdit. The new version is compiled with Java 1.5 and is compatible with the latest version of jEdit. Also new in this version is support for validating JavaScript that is embedded in an XML document — there is support for XHTML, XUL, and XBL. Note that you will have to manually set the parser to “xmljavascript” (rather than just “javascript”) to get it to work. See the download page for more information:
any plans for adding javascript code completion in this plugin.
