    <!doctype html>      <html>      <head>      	<title>more events</title>      </head>      <body>      	<form>      		<input type="text" value="your email" name="email" id="email" />      	</form>            	<script>      		var emailfield = document.getelementbyid('email');      		 emailfield.onfocus = function(c) {      		 	if (emailfield.value == 'your email')      		 		{      		 			emailfield.value == '';      		 		}      		 	}      		 emailfield.onblur = function(c) {      		 	if (emailfield.value == '')      		 		{      		 			emailfield.value == 'your email';      		 		}      		 	      		 }      	</script>            </body>      </html>

you using comparison operator(==) instead of assignment operator(=) here:

emailfield.value == '';

change to

emailfield.value = '';

in code:

var emailfield = document.getelementbyid('email');          emailfield.onfocus = function(c) {             if (emailfield.value == 'your email')                 {                     emailfield.value = '';                 }             }          emailfield.onblur = function(c) {             if (emailfield.value == '')                 {                     emailfield.value = 'your email';//also here                 }           }
