store prompt input in array, display array help.

**jonblaze87** · 04-30-2007 10:08 PM

This is what I'm trying to figure out. User inputs as many names as they want in a prompt until they input nothing. The names are stored in an array and displayed.

ok, so I know how to display the stored names if I know how many prompts there are going to be, like this:

var name= new Array(5);
var y=0;
for (y=0; y<5; y++)
{
name[y]=prompt('Enter a name!',' ');
}
var x=0;
for (x=0; x<5; x++)
{
document.write(name[x] + "<br>");
}

And I know how to keep asking for prompt until the user enters nothing, like this:

do
{
name = prompt("Enter some names");
}
while (name != ' ');

Thats the problem, I can't figure out how to prompt and store since I have no idea how many prompts there will be and I dont know if I can combine these 2 codes or some other way to do it.
Any help is apreciated.

Does pushing the elevator button more than once make it arrive faster?

Of course it does.....just like hitting a submit button multiple times makes the data process faster!
