Menu
i have to create a website that has javascript that inputs a password, and checks for three things:
1)must be at least 8 characters
2)must contain one capital letter
and 3) must contain at least one number.
below is my code so far, but i cant seem to get the alert windows to pop up telling whether or not the password is valid. Any help is greatly appreciated.
[code=php]

<script type=”text/javascript”>

function Start()
{
var password;
var passwordArray = new Array(password.length);
var has8charicters = false;
var numeric = false;
var upperCase = false;
for(var i=0; i<password.length; i++)
{
passwordArray[i] =password.substring(i, i+1);
}
if(password.lenght>=8)
{
has8charicters = true;
numeric = checkNumeric(passwordArray);
upperCase = checkUpperCase(passwordArray);
}
if(has8chariters && numeric && upperCase)
{
alert(“vaild”)
}
else
{
alert(“not vaild”)
}
}
function checkNumeric(anArray)
{
for (var i =0; i<anArray.length; i++)
if(anArray[i]>=”0″ && anArray[i]<=”9″)
return true;
}
function checkUpperCase(anArray)
{
for(var i = 0; i<anArray.lenght; i++)
if(anArray[i]>=”A” && anArray[i]<=”z”)
return true;
}
