How to Install Javascript

By Gigi Starr

Javascript is actually part of the Sun Microsystems Java Runtime Environment; it's not a program in and of itself. It's a programming language that Web designers use in order to add dynamic content to a Web page. Installing Java is a simple procedure, and is completely free.

Things You'll Need

  • Windows, Solaris, MacOS or Linux operating system

Step 1

Visit the Java website listed in the Resources below. "Java Downloads for All Operating Systems," will open in your browser.

Step 2

Make certain that your browser allows Java and Javascript to run. To confirm this, check your browser's "Preferences" or "Options" menu. Under the Content or Page Options menu, there will be several check boxes for Java. Make sure each is filled. For Firefox users running the No Script plug-in, make sure that "" is selected as a permitted site.

Step 3

Find your operating system on the page. Included systems are Windows, Solaris, Linux and MacOS. Click on the link that coincides with your operating system type. A dialog box will pop up asking if you'd like to save the file. Click "OK." Close all open applications at this time.

Step 4

A Java icon will be on the desktop. Double click this to begin installation. The installer will unpack, and you'll be prompted to read the License Agreement. Click "Accept" or "Decline." If you select the latter, the install will cancel, and you won't be able to run Java.

Step 5

Accept or decline any third-party software that the installer offers as desired. Click "Next" to proceed with the install.

Step 6

Wait for a message to pop up saying, "Thank You!" The install is complete. To test the installation, open your browser once again and return to the download page. Scroll down to the appropriate download location and click "Verify Java has been installed correctly." You'll then see a blue button that says, "Verify Java version." This will tell you that you've successfully installed the program. If not, repeat this tutorial to reinstall.
