Im new to Javascript.
Im trying to code these four buttons. I'm currently on the second one. I've coded an array. But when I click on the button, it replaces the page. I want to display the array in an alert box.
<html>
<head>
<script type="text/javascript">
function SayHello()
{
alert("Hello World!");
}
function DumpCustomers()
{
var aCustomers=new Array();
aCustomers[0]="Frank Sinatra ";
aCustomers[1]="Bob Villa ";
aCustomers[2]="Kurt Cobain ";
aCustomers[3]="Tom Cruise ";
aCustomers[4]="Tim Robbins ";
aCustomers[5]="Santa Claus ";
aCustomers[6]="Easter Bunny ";
aCustomers[7]="Clark Kent ";
aCustomers[8]="Marry Poppins ";
aCustomers[9]="John Wayne ";
document.write(aCustomers[0]);
document.write(aCustomers[1]);
document.write(aCustomers[2]);
document.write(aCustomers[3]);
document.write(aCustomers[4]);
document.write(aCustomers[5]);
document.write(aCustomers[6]);
document.write(aCustomers[7]);
document.write(aCustomers[8]);
document.write(aCustomers[9]);
}
function DisplayFishCounts()
{
}
function FindJonGalt()
{
}
</script>
</head>
<body>
<form name="Main">
<input type="button" id=1 onclick="SayHello();" value="Say Hi"/>
<input type="button" id=1 onclick="DumpCustomers();" value="Dump Customers"/>
<input type="button" id=1 onclick="DisplayFishCounts();" value="Display Fish Counts"/>
<input type="button" id=1 onclick="FindJonGalt();" value="Where is Jon Galt?"/>
</form>
</body>
</html>

javascript
arrays
popup
alert
If you want to see the array as an array, you can say
alert(JSON.stringify(aCustomers));
instead of all those document.writes.
However, if you want to display them cleanly, one per line, in your popup, do this:
alert(aCustomers.join("\n"));
