JQuery :: Click To Create Text Box

I have written code that achieves three things: Once the user clicks (1) A text box is created (2) It is positioned based on the position of the cursor (3) The focus is set to the text box. It works great, but the problem is if you click somewhere else, in addition to creating a new text box it also moves the previous text box.

$(document).click(function(e){
$("body").append("<input />");
$("input").css({ left: + e.pageX, top: + e.pageY });
$('input').focus();
});
