when i submit form using enter key code example

Example 1: javascript submit form when enter key pressed

//submit form when 'Enter' key is pressed while in myInputID
document.getElementById("myInputID").addEventListener("keyup", function(event) {
    if (event.keyCode === 13) {
    	document.getElementById("myFormID").submit();
		return false;
    }
});

Example 2: how to send a form when you hit the enter key

use the "submit" feature instead of the "button" feature, I.E.

<input type="submit" value="login" onclick="password(this.password)">
