Question

I have an input field and a login button. I want to allow users to hit the “enter” key to click the button when the input field is focused. How would I do this with jQuery?

<input type="text" size="10" id="loginUserID" name="username">
<input type="button" value="Login" name="loginBtn" id="loginBtn">

Answer 1

$('#loginUserID').keypress(function(event){
  if(event.keyCode == 13){
    $('#loginBtn').click();
  }
});
