javascript - getting html and jscript to validate a password? -

just quick question im unsure why not working

html:

<label>password </label> <input type="password" id="pword"><br> <label>confirm password </label>  <input type="password" id="confpword"><br> 

js:

function passwordvalidation(){      var username = document.getelementbyid("unamem");     var password1 = document.getelementbyid("pword");     var confpword1 = document.getelementbyid("confpword");      if (password1 != confpword1){         window.alert("passwords don't match")     }else{         window.alert("well done match")     }      } 

surely code should work? whatever type in, never hits else block. ideas?

thanks

change if

 if (password1.value != confpword1.value){    window.alert("passwords don't match") }
