JavaScript is usually enabled by default, but if it’s disabled, it can be enabled through browser settings. Enabling JavaScript can affect browsing experience, but specific settings can control its actions. It’s an advanced setting usually found under “scripts and plug-ins” in the browser’s advanced setup submenu.
The best advice for enabling JavaScript® is to realize that it is almost always enabled by default, so that no web browser user action is required for scripts written in this language to run. If JavaScript® has been disabled for some reason, however, enabling it isn’t difficult. These tips are helpful in enabling JavaScript®: a familiarity with how to change settings in your web browser, an understanding that functionality on some web sites will be lost, and an understanding that scripts written in this popular programming language behave differently in various web browsers. Even when JavaScript® is enabled, it can still be controlled through specific optional settings in your browser.
Enabling JavaScript® opens a menu in your browser, usually offering the ability to edit and might be called “edit”. After the menu has been activated, there is usually another option called “preferences” that the user would have to click on to bring up a window with even more options. These options are categorized into the many settings that can be changed. The options are almost always presented in a hierarchical order consisting of sub-menus which may need to be opened by clicking on or next to the main header or possibly holding the mouse pointer over the title. The “edit” and “preferences” titles might have different names in different browsers, but the names usually indicate what options are offered to the user.
Most web browsers consider enabling JavaScript® an advanced setting and place that option under a header that might say “advanced”. An advanced setup submenu will typically list “scripts and plug-ins” as an option that users can click to see the actual place where JavaScript® is being enabled. Some very specific options that can also be enabled or disabled are usually present at this point. Browser users should understand that enabling JavaScript® is not necessarily an all-or-nothing decision. You can allow scripts encoded in this language to run while maintaining control over some of the ways JavaScript® scripts can affect your browsing experience.
For example, depending on the specific web browser you are running, JavaScript® may be enabled for your browser as well as mail and newsgroups. Actions allowed or forbidden for scripts include moving or resizing existing windows, raising or lowering windows, and hiding the status bar. Other actions that settings can allow or block include changing the text that appears in the status bar, changing images, and disabling or replacing context menus. If you’re not sure what a status bar is, it might not be a good idea to change these settings, because it might not be able to do certain things on websites that run scripts that affect the status bar.
