this working code you.

function validate(event) {    event.preventdefault();    var pattern = /^(?=.*[a-z].*[a-z])(?=.*[a-z])(?=.*\d)[a-za-z\d]{8,32}$/;    var pwd = document.form.password.value;    var confpwd = document.form.confpass.value;    if (!pwd.match(pattern)) {      alert("password must between 8 32 characters,\n have @ least 1 digit \n 2 lower , 1 upper case letters.");      document.form.password.focus();      return false;    } else if (pwd != confpwd) {      alert("passwords not match. please try again.");      document.form.password.focus();      document.form.confpass.focus();      return false;    } else {      document.form.submit();    }  }

<form name="form" method="post" action="registerpath" onsubmit="return validate(event);">    <table class="box">      <tr>        <td class="left">password:</td>        <td><input type="password" name="password" placeholder="enter password" required /></td>      </tr>      <tr>        <td class="left">confirm password:</td>        <td><input type="password" name="confpass" placeholder="re-enter password" required /></td>      </tr>      <tr>        <td colspan="2"><button type="submit">submit</button></td>      </tr>    </table>  </form>
