问题

I have a image and in it wants to be fadein fadeout automatically when the document is loaded and it should be done till the document is closed .. help me plzz

回答1:

this'll do it:

$(function () {
    $('#fader').fadeIn('slow', function () {
        fadeItOut();
    });
});

function fadeItIn() {
    $('#fader').fadeIn('slow', function () {
        fadeItOut();
    });
}

function fadeItOut() {
    $('#fader').fadeOut('slow', function () {
        fadeItIn();
    });
}

with

fader being the id of your image

回答2:

$( function() {
    var t = 500;
    setInterval( function(){
        $('#id').fadeOut( t, function(){ $(this).fadeIn( t ); } );
    }, 2*t);
});

id is the image id and t is the interval.
