This code will create passwords randomly using simple Javascript. It also contains an option to provide the length of the password.
By default I have given length of the password as 8 but it is up to your use case on what that value should be.
Change it inside onclick="password(8)"
We can also pass a value to the function as password(8,true) or password(8,false). If value is true then you can get special characters in your password.
<script type="text/javascript">
//script from Mistonline.in (Please dont remove this line)
function password(length, special) {
var iteration = 0;
var password = "";
var randomNumber;
if(special == undefined){
var special = false;
}
while(iteration < length){
randomNumber = (Math.floor((Math.random() * 100)) % 94) + 33;
if(!special){
if ((randomNumber >=33) && (randomNumber <=47)) { continue; }
if ((randomNumber >=58) && (randomNumber <=64)) { continue; }
if ((randomNumber >=91) && (randomNumber <=96)) { continue; }
if ((randomNumber >=123) && (randomNumber <=126)) { continue; }
}
iteration++;
password += String.fromCharCode(randomNumber);
}
document.getElementById('pwd').innerHTML=password;
}
</script>
The above Javascript will simple display some random characters according to the length and we update the div element with ID = PWD
We are calling the Javascript function by triggering a button.
The New Password is <font color="red"><div id="pwd"></div></font>
<form>
<input onclick="password(8)" type='button' value="Generate Random Password Now" id="submit"/>
<input onclick="password(8,true)" type='button' value="Generate Random Password With Special Char" id="submit"/>
</form>
