Embedding Sound in Web Pages, Part I: A Plugin Object Example - Doc JavaScript


A Plugin Object Example

We'll round up this section about plug-ins and Plugin objects, by an example that prints the list of plug-ins. Our list resembles the output of the "About Plug-ins" option in the "Help" menu entry of Netscape Navigator. The script is a straightforward loop through the plugins array, creating a separate row for each plug-in. We extract the number of plug-ins from the plugins.length property. Here is the code for the loop:

for (var i = 0; i < navigator.plugins.length; i++) {
  document.write("<TR VALIGN='top'><TD>", i, "</TD>",
    "<TD>", navigator.plugins[i].name, "</TD>",
    "<TD>", navigator.plugins[i].description, "</TD>",
    "<TD>", navigator.plugins[i].filename, "</TD>",
    "<TD>", navigator.plugins[i].length, "</TD></TR>");
}

And here is a sample output:
