代码:


<!DOCTYPE html>
<html lang="en">
<head>
 <meta charset="UTF-8">
 <meta name="viewport" content="width=device-width, initial-scale=1.0">

 <input type="text">
 <button>生成</button>
 <div class="end"></div>
 <script>
 var oTn = document.getElementsByTagName("input")[0];
 var oBtn = document.getElementsByTagName("button")[0];
 var oDiv = document.querySelector(".end");
 var password = ["a","b","c","d","e","f","g","h","i","j","k","l","m","n","o",
 "p","q","r","s","t","u","v","w","x","y","z","A","B","C","D",

 "T","U","V","W","X","Y","Z","0","1","2","3","4","5","6","7","8","9"
 ]; 
 function pass(length){
 var Str = "";
 for(var i = 0 ; i<length;i++){
 Str += password[Math.floor(Math.random()*password.length)];
 }
 return Str;
 }
 oBtn.onclick = function(){
 oDiv.innerHTML = pass(oTn.value);
 }
