You connect to the
window
object's
onload
event handler by adding an attribute to the opening
<body>
tag.
<body onload=”displayLinks()”>
On the
onload
event fi ring, this will run the script in quotes calling the
displayLinks()
function.
In this function you use a
for
loop to cycle through each
a
object in the
document
object's
links
collection.
function displayLinks()
{
var linksCounter
for (linksCounter = 0; linksCounter < document.links.length; linksCounter++)
{
alert(document.links[linksCounter].href);
}
}
You used the
length
property of the
links
collection in your condition to determine how many times
you need to loop. Then, using an alert box, you display each
a
object's
href
property. You can't use
document.write()
in the
load
event because it occurs when the page has fi nished loading.
