Question

Here’s my code:

   $('#details').hover(function() {
    var tag = 'div.cds'
    var offset = $(this).position();
    var width = $(tag).outerWidth();
    var height = $(tag).outerHeight();
    $(tag).show();
    $(tag).css('left', offset.left - width + 'px');
    $(tag).css('top', offset.top - height + 'px');
}, function() {
    $(tag).hide();
});

When I “mouseout”, the variable “tag” does not hide.

Thanks!

Answer 1

Learn about scope

var tag = 'div.cds'
 $('#details').hover(function() {
    var offset = $(this).position();
    var width = $(tag).outerWidth();
    var height = $(tag).outerHeight();
    $(tag).show();
    $(tag).css('left', offset.left - width + 'px');
    $(tag).css('top', offset.top - height + 'px');
}, function() {
    $(tag).hide();
});

The tag variable did not exist in the second function’s scope. So i added tag to the global scope. and it should work now.
