Chapter 12. Behaviors and JavaScript > Browser JavaScript Support

12.1. Browser JavaScript Support

Dreamweaver's behaviors are implemented in JavaScript and therefore require a JavaScript-capable browser. Table 12-1 lists the JavaScript versions supported by the major browsers. (Microsoft's implementation of JavaScript is called JScript. Although JScript is very similar to JavaScript, it is not identical. If you create your own behaviors, test them in both Internet Explorer and Netscape.) Note that Dreamweaver's JavaScript debugger works with NN4.5+ (Macintosh and Windows) and IE4+ on Windows, but not earlier browsers, IE for Macintosh, NN6, or Opera.
