JavaScript: Array Objects - Join() Hands
(Page 2 of 5 )
As stated in our nifty table, join() places all of the elements in an array inside of a string. The values are separated by a delimiter of your choosing. This parameter is optional, however; you can choose to not specify a delimiter. Here is the method in action:
<html>
<body>
<script type="text/javascript">
var bboys = new Array(3);
bboys[0] = "Greg";
bboys[1] = "Bobby";
bboys[2] = "Peter";
document.write("Behold the Brady Boys: " + "<br />");
document.write(bboys.join() + "<br />");
document.write(bboys.join(".") + "<br />");
document.write(bboys.join("|") + "<br />");
document.write(bboys.join("-----") + "<br />");
document.write(bboys.join("[]") + "<br />");
document.write(bboys.join(""));
</script>
</body>
</html>
This gives us the result:
Behold the Brady Boys:
Greg,Bobby,Peter
Greg.Bobby.Peter
Greg|Bobby|Peter
Greg-----Bobby-----Peter
Greg[]Bobby[]Peter
GregBobbyPeter
As you can see, we can practically use anything (or nothing at all) as a delimiter. The comma is the default delimiter when using the join() method.
