Imitate the password input box implementation Code _JAVASCRIPT skill

Examples are as follows:

function Hiddenpass (event) {
  var password0 = document.getElementById ("password0");
  var password1 = document.getElementById ("Password1");

  if (Event.keycode = =) {
  }

  var keycode;
  if (window.event) {//IE
    keycode = Event.keycode
  } else if (Event.which) {//Netscape/firefox/opera
    keycod E = Event.which
  }
  var Keychar = String.fromCharCode (keycode);
  Password1.value = Password1.value + Keychar;
  Password1.value = password1.value.substring (0, password0.length);
}

function Clearpass () {
  $ ("#password0"). Val ("");
  $ ("#password1"). Val ("");


<li class= "ba" ><label> password:</label>
  <input type= "text" id= "password0" onfocus= "
      Javascript:clearpass (); "
      Onkeyup= "This.value=this.value.replace (/./g, ' * ')"
      onkeypress= "Javascript:hiddenpass (event);" />
  <input type= "hidden" id= "Password1" name= "Password1"/>
</li>

The above simulation of the Password input box implementation code is a small series to share all the content, hope to give you a reference, but also hope that we support the cloud habitat community.
