The main purpose of this script is to show only the main content or page article. It is designed to be used with a bookmarklet whose URL is (no quote) "javascript:void(PCVM())". There can be up to 5 to 7 view modes depending on the layout of the web page.
目前为
The first time the bookmarklet is clicked, the script will try to show only the main content (i.e. without page header & footer, top menu, sidebar, etc.). Depending on the web page layout, it may not show all of the main content. So, subsequent click to the bookmarklet will widen the visibility of the content. e.g. content title, then content footer, then sidebars, etc.
