问题
At work, We use a pretty old browser(symbol's pocket browser) that supports only JS 1.2. Deploying code to the test device running that browser is a bit painful. Is there any open source/free tool available that would allow me to check locally in a PC (running Windows XP/Firefox 3.6.8) whether the code written is compatible with JS 1.2? Thanks in advance.
回答1:
You could try using <script language="JavaScript1.2">.
