Hello,
I want to write a program.
in the program i need to generate a password that contain 8 - 10 charachters.
i did it, but without regex, Can any one help me, how to do this with the regular exp ?
the criterias for the pass are:
1- the length 8 -10 chars.
2- the pass must contain just [a-z] or [A-Z] or [0-9].
3- i must use the char just once in the all pass
sorry for myweak eng
I hope that u understand me, and i hope that u help me.

A regex is typically for checking/replacing a string, not creating one.
Yes, exactly
I write the code.
<html>
<head>
<title>password generaton</title>
</head>
<BODY>
<SCRIPT LANGUAGE="JavaScript">
function randomPassword()
{
var repeats = /(.)\1/;
var length = randomFromTo(8,12);
chars = "abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ1234567890";
pass = "";
for(x=0;x<length;x++)
{
i = Math.floor(Math.random() * 62);
pass += chars.charAt(i);
}
if(repeats.test(pass)){
randomPassword();
}
return pass;
}
function formSubmit()
{
passform.passbox.value = randomPassword();
return false;
}
function randomFromTo(from, to){
return Math.floor(Math.random() * (to - from + 1) + from);
}
// End -->
</script>
<table align="center" border="1">
<tr>
<td valign="middle" align="center">
<center>Random Password Generator</center>
<form name="passform">
Password: <input name="passbox" type="text" size="50" tabindex="1"></p>
<p>
<input type="button" value="Generate" onClick="javascript:formSubmit()" tabindex="2"> <input type="reset" value="Clear" tabindex="3"></p>
</form>
</td>
</tr>
</table>
</html>but it doesn't work, it's check if the are two cahrs repeating, i.g if the pass is hello, so can to match it.
but i want to check all the pass not only every two chars
i.g: welcome, i want to match it because it's contains the lchar "e" more than once.
