How can I turn on JavaScript ?

Answer 1

While asking a question you should ask clearly such as for which Browser and for which OS you are expecting.
I am giving you all the details for different browsers in different OS:

Click the "OK" button. Close this window and click the "Refresh" button of the page requiring Javascript.

Find the "Preferences" option in the menubar of your browser (it's probably located in the Edit menu). Select the "Advanced" arrow in the list on the left side of the window. Make sure that the checkbox next to "Enable JavaScript" is checked. Click the "OK" button. Close this window and click the "Reload" button of the page requiring Javascript.

Note to AOL 4.0 & 5.0 users

When using the use AOL browser, you may get a Javascript error but, when using an external browser (i.e., Netscape or Internet Explorer) this does not occur. AOL uses compressed graphics by Default. This doesn't allow Java to work while browsing inside AOL. (Additionally, this makes photos you view on web pages look less than optimal.)

Do the following:

1. Click My AOL.
2. Click Preferences.
3. Click the WWW icon.
4. Click Web Graphics tab.
5. Uncheck the box next to Use Compressed Graphics.
6. Click OK Restart the computer.

Note that there are both 16-bit and 32-bit versions of AOL 4.0. Only the 32-bit version has full Java capabilites.
