javascript - Does something like jQuery.toggle(boolean) exist?

I write something similar to the following code a lot. It basically toggles an element based on some condition.

In the following made-up example, the condition is "If the agree checkbox is checked and the name field isn't empty".

$("button").click(function() {
  if ($("#agree").is(":checked") && $("#name").val() != "" ) {
    $("#mydiv").show();
  } else {
    $("#mydiv").hide();
  }
});

I wish there was some sort of jQuery function that would work like this.

$("button").click(function() {
  var condition = $("#agree").is(":checked") && $("#name").val() != "" );
  $("#mydiv").toggle(condition);
});

Is there something like this out there? Or are there other ways besides the first example to do this in a less if-else-ish way?

Ok, so I am an idiot and need to RTM before I ask questions.

jQuery.toggle() allows you to do this out of the box.

$("button").click(function() {
  var condition = $("#agree").is(":checked") && $("#name").val() != "" );
  $("#mydiv").toggle(condition);
});
