Example #1

Example of using the body tag's events:  onLoad() & onUnload().

Click here - if you came to this page from a search engine. This page was designed to be viewed in a series of training pages.

This pages functionality: (Look at the HTML source's JavaScript)

• Look at the HTML source.  The body tag calls fonLoad() when the page loads and fonUnload() when the page unloads.
• fonLoad() function creates a popup message using the alert() function.
• fonUnload() function creates a popup message using the alert() function, then creates a new window with ex_window_bodytab_load2.htm as the web page.

Differences using IE vs Netscape:  (I'm using IE 5.5 & NS 4.7)

• onLoad() event's alert() function works in both IE & Netscape.
• onUnload()
  • If browser window is closing,  event's  work in IE, but do not  work in Netscape.
  • If browser is changing URL's but is still open, event's work with IE & Netscape.
    • Netscape note - as long as the window is open, when pages are unloaded Netscape will call the onUnload() event.

Do the following to test:

• Close the browser window by clicking on the "X" in the upper right corner.
• Goto another URL by typing in your favorite site.
• Goto another URL by clicking on this link:  www.yahoo.com
