html and javascript password: how to change display of an element if the password is correct? -


i need make password protected image in html of javascript, means, if enter correct password, image appear.i'm beginner, can't find error in this. don't know if if code written, thankful if help.

html:

    <img src="..." id="smiley"/>      <form>          picture password protected<br>enter password:<br>          <input type="password" name="password" id="password">          <input type="button" onclick="funcpass( );" value="ok">      </form>

javascript:

    var password = getelementbyid("password").value;     function funcpass(password.value) {         if (password.value == "smiley")         {             document.getelementbyid("smiley").style.display = "block";         }         else         {             password.value = " ";         }      }

in css changed image display property none

your code password needs in function itself. you're getting value twice (the value of value). try this:

function funcpass() {     var password = document.getelementbyid("password").value;     if (password == "in darkened room")     {         document.getelementbyid("smiley").style.display = "block";     }     else     {         password = "";     }  }
