Random Password Generator using Javascript


Welcome to I am going to teach you how to make a random password generator that you can use in you projects or systems. Just follow the instructions below.


First, let's create our html code, just copy the code below.

  1. <form name="pgenerate">
  2. <input type="text" size=18 name="output">
  3. <input type="button" value="Generate Password" onClick="populateform(this.form.thelength.value)"><br />
  4. <b>Password Length:</b> <input type="text" name="thelength" size=3 value="7">
  5. </form>

Lastly, we will be creating our javascript code.

  1. <script>
  2. var keylist="abcdefghijklmnopqrstuvwxyz123456789"
  3. var temp=''
  5. function generatepass(plength){
  6. temp=''
  7. for (i=0;i<plength;i++)
  8. temp+=keylist.charAt(Math.floor(Math.random()*keylist.length))
  9. return temp
  10. }
  12. function populateform(enterlength){
  13. document.pgenerate.output.value=generatepass(enterlength)
  14. }
  15. </script>

Virus note: All files are scanned once-a-day by for viruses, but new viruses come out every day, so no prevention program can catch 100% of them.


1. Re-scan downloaded files using your personal virus checker before using it.
2. NEVER, EVER run compiled files (.exe's, .ocx's, .dll's etc.)--only run source code.
