How Do You Enable Javascript on a Phone?

Javascript is a simple programming code that Web developers use to make interactive widgets and Web pages. According to Boutell.com, it was known as Livescript before Netscape and Sun Microsystems agreed to change its name. Since it lets you run powerful Web applications--notably Gmail--it's a necessary component of any smartphone. To enable it, a smartphone user needs to adjust the settings on her browser program--Safari on the iPhone, Blackberry browser on Blackberry and the Android browser on Android phones. The latter class of smartphones have Javascript enabled by default.

How to Enable Javascript On Other Popular Phones

Step

If you have a Windows Mobile phone, download a version of the Opera browser. According to Microsoft, since the default browser for Windows Mobile phones, Internet Explorer, can run only a small subset of Javascript functions, you will need a new browser to run most Javascript applications. A writer at Boutell.com suggests that you download Opera's free browser, use it to open up a new Web page and then click on the "Tools" tab. Open the "Quick Preferences" menu and check the "Enable Javascript" box.

Step

If you're an Android user, open up the "Options" menu and search for the "Set Javascript Enabled" prompt. By default, it should be enabled; if it isn't, set it to “True.”

Step

If you use another smartphone, enter the preferences menu of your browser and search for the Javascript option. Older phones--especially phones sold before the advent of 3G networks--may not support the language. If your phone does not support Flash or Java, there's a good chance that it doesn't have the processing power to support Javascript.
