一个函数，它返回一个字符串，该字符串在数组中包含指定数目的子字符串。这与拆分方法完全相反。
Join(List[,delimiter])
<!DOCTYPE html>
<html>
<body>
<script language = "vbscript" type = "text/vbscript">
' Join using spaces
a = array("Red","Blue","Yellow")
b = join(a)
document.write("The value of b " & " is :" & b & "<br />")
' Join using $
b = join(a,"$")
document.write("The Join result after using delimiter is : " & b & "<br />")
</script>
</body>
</html>
结果：
The value of b is :Red Blue Yellow The Join result after using delimiter is : Red$Blue$Yellow
