Access $(this) from a .toggle

$('element').toggle(
    function() {开发者_开发技巧
        alert($(this).offset.top);
    },
    function() {

You need to call the offset() function in order to retrieve the top property:

$('div').toggle(
    function() {
        alert($(this).offset().top);
    },
    function() {

    }
);

offset is a function. That should be

alert($(this).offset().top);
