Finally, getURL() can also be used to execute JavaScript code. Here we invoke a simple

JavaScript alert using getURL():

getURL ("javascript: alert('hello world');");

Note that execution of JavaScript code from a URL does not work in Internet Explorer 4.5

for Macintosh.

Example

Here’s the code for a standard button that links to a web page:

link_btn.onRelease = function () {

getURL("http://www.macromedia.com/");

}

Bugs

Internet Explorer 4.5 (IE 4.5) and older versions on Macintosh do not support the "POST"

method of a getURL( ) call. To service those browsers, use "GET" instead of "POST" (subject

to the length limitations cited earlier).

In most browsers, relative URLs passed to getURL( ) are resolved relative to the HTML file

that contains the .swf file. In IE 4.5 and older versions on Macintosh, relative links are

resolved relative to the location of the .swf file, not the HTML file, which causes problems

when the two are in different directories. To avoid the problem, either place the .swf and

.html files in the same directory or use absolute URLs when invoking getURL( ), such as:

getURL ("http://www.someserver.com/")
